Samsung Q80T vs Q70T Review

Samsung Q80T and Q70T are parts of the Samsung’s 2020 QLED TV Lineup. In this lineup, they sit between the Q90T and Q60T. If we see their series number, can be ascertained that the Samsung Q70T is the successor of the Q70R while Q80T is the successor of the Q80R. But you need to know, if we see their performance, in this year, the lineup of the QLED TV has been downgraded from their predecessor.  This means, the Q70T is the successor of the Q60R while the Q80T is the successor of the Q70R.

In the market, both of them come in 5 screen sizes options. The difference, the Q70T is available on 82 inch but the Q80T is not, while the Q80T is available on 49 inches while the Q70T is not. Meanwhile, except these sizes, they come in the same screen sizes, which are 55 inches (QN55Q80T vs QN55Q70T), 65 inches (QN55Q80T vs QN65Q70T), 75 inches (QN75Q80T vs QN75Q70T), and 85 inches (QN85Q80T vs QN85Q70T. And with the same screen sizes, the Q80T as the higher model is sold hundreds dollar more expensive than the Q70T, depending on the screen sizes. So, what are the main differences between the Q80T and Q70T and which is a better choice based on the value/price?

The Main Differences of Samsung Q70T and Q80T

Backlight Technology

Direct LED vs Edge Lit

Nevertheless, although they use the same panel technology but their backlight technology is different. If the Q70T uses Edge-LED Lit backlight, the Q80T use Direct LED backlight. Additionally, the Q80T has full array local dimming while the Q70T doesn’t have any local dimming feature. As we have known, local dimming feature can improve the TV’s performance in a dark room by improving contrast ratio and minimizing blooming.

Additionally, to dim their backlight, they both may use the same PWM (Pulse-Width-Modulation) dimming system. But in most picture mode, they use different dimming frequency. In most picture modes, the dimming frequency of the Q80T is 960 Hz while the Q70T is 600 Hz. And since their dimming frequency is equally very, this makes their backlight flicker should not be noticeable for most people. But in certain setting where their Black Frame Insertion (BFI) mode is enabled, their dimming frequency will change to 120 Hz or 60 Hz, depending on setting.

Ultra Viewing Angle

As we see on comparison table above, except the 49 inches variant (QN49Q80T), the Samsung Q80T already has Ultra Viewing Angle technology. This technology is designed to improve side viewing angle of Samsung TV. Unlike IPS panel that has good side viewing angle but its native contrast ratio is poor, the Ultra Viewing Angle improve side viewing angle coverage while native contrast ratio is still maintained. The result, the Samsung Q70T has both good side viewing angle and at the same time also has excellent native contrast ratio.

Sound Output

Their sound system becomes the other difference between the Samsung Q70T and Q80T. As we see on comparison table above, the Q80T is equipped with 2.2.2 channel speaker system with total sound output 40 watts. Meanwhile, special for the 49 inches model of the Q80T (QN49Q80T), it has 2.2 channels system with 40 watts of sound output. On the other hand, the Q70T is only equipped with standard sound system for most TVs, which is 2.0 channel system with 20 watts of total sound output.

HDR Numerical Index

This is a result of measurement made by Samsung to find out the HDR output of each model of their model. We don’t know for sure the parameters that be used. But for sure, the higher HDR Numerical Index of Samsung TV, the better HDR performance of this TV. And as we see on comparison above, the Samsung Q70T has HDR Output Quantum HDR while the Q80T has Quantum HDR 12X, except its 49 inches model (QN49Q80T) that has Quantum HDR 8x. Can be ascertained, HDR performance of the Q80T is better than the Q70T.

Similarities

Panel Technology

Quantum Dot Technology

Both Samsung Q70T and Q80T may use the same panel technology, which is VA Panel that supported by Quantum Dot Technology. Since they both use VA panel, can be ascertained, they both have excellent native contrast ratio. This certainly makes them can produce deep black, as is typical of LED TV with VA panel. But this doesn’t mean the VA panel doesn’t have a shortcoming. The main shortcoming of the VA Panel is side viewing angle where a TV with VA panel usually has poor side viewing angle coverage. While the support of the Quantum Dot technology make them can produce wide color gamut that is required to show HDR images colorfully.

Image Processors

Both Samsung Q80T and Q70T are powered by the same image processor, which is a powerful images processor called Quantum Processor 4K. In addition it is able to process images excellently, their image processor also allow them have some AI-Related features such as 4K AI Up-Scaling, Adaptive Brightness, Adaptive Sound, and Adaptive Volume. Additionally, their image processor also allows their smart TV runs smoothly.

Motion Technology

Except the 49 inches model of the Q80T (QN49Q80T), both of the Samsung Q70T and Q80T are powered by the same motion technology. To improve their performance in handling motion, they both are powered by Motion Rate 240 technology. Additionally, they both also have the same native refresh rate panel, which is 120 Hz. Not only that, they both also already support Variable Refresh Rate technology that compatible with FreeSync and HDMI Forum VRR. At 1080p and 1440p, their refresh rate can change between 20 – 120 Hz while at 4K resolution, their refresh rate can change between 48-60 Hz. As we have known, the VRR technology can improve their game experience by reducing screen tearing.

Additionally, both of the Samsung Q80T and Q70T also have an optional BFI (Black Frame Insertion) mode that help motion smoother, particularly when they are playing 60 fps content. As we have discussed a bit above, in most mode, the dimming frequency of the Q80T is 960 Hz while Q70T is 600 Hz. Their dimming frequency will change to 120 Hz. To change their dimming frequency to 120 Hz, you must make certain setting. On Q80T, entering in “Standard”, “Natural”, “Dynamic”, and “Game” mode will change its dimming to 120 Hz. Additionally, entering in “Movie” mode while the “Picture Clarity” is set to “Custom” or “Auto” also will make its dimming frequency drops to 120 Hz.  Meanwhile, on Q70T, entering in “PC” mode (without Game mode) and entering in “Game” mode with “Game Motion Plus” enabled makes its dimming frequency drops to120 Hz. Keep in mind, entering in “PC” mode while “Game” mode is still enabled makes its dimming frequency is still 600 Hz.

Meanwhile, to change their dimming frequency to 60 Hz, you just need to turn on “LED Clear Motion”. But keep in mind, not in all modes when you enable “LED Clear Motion” their dimming frequency will change to 60 Hz. In Game mode, on q70T, although you enable “LED Clear Motion” their dimming frequency is still 120 Hz.

Inputs

Both of them also have the same outputs/inputs. As their major connectivity, both Samsung Q70T and Q80T are equipped with 4 HDMI ports where their HDMI ports support most of formats. In addition CEC, HDCP 2.2, HDMI 2.0, ARC (HDMI 3), they both also already support HDMI 2.1 Full bandwidth and eARC (enhanced Audio Return Channel). But for a while, their HDMI port that supports HDMI 2.1 is only 1, which is HDMI 4. Meanwhile, resolution that supported by them are also similar where they support most of resolution like 1080p @ 60Hz, 1080p @ 120 Hz, 1440p @ 60Hz, 1440p @ 120 Hz,  4K @ 60 Hz, 4K @ 60 Hz with HDR, and others. But keep in mind, although they both already support HDMI 2.1, it seems they don’t support HFR (High Frame Rate) content like 4K @ 120HZ. Samsung may be going to fix this in future software update.

IN addition to HDMI ports, they both also have 2 HDMI ports. But just like other models of Samsung TVs, their USB ports are only support USB 2.0 and don’t support USB 3.0. They both also have 1 RF Input (Tuner In), Digital Audio Out (optical), and 1 Ethernet ports. Lastly, for wireless connection, they both are equipped with built-in Bluetooth and Wi-Fi. They both don’t have Composite In and Component In.

Smart TV Platform

Both Samsung Q70T and Q80T run the same smart TV platform, which is Tizen 2020 and their smart TV performance is also similar. As we have known, Tizen OS has intuitive, simple and easy to use interface which runs smoothly. Compare previous model, there is not many changes on the layout and interface. Just like previous version, it has also has attractive and interesting pre-installed apps. There are VoD Service such as YouTube, Netflix, Amazon Videos, and others, Web Browser, Games, Live TVs, and others. Additionally, its smart TV also has an apps store called Samsung Apps Store that has excellent selections of apps where you can download them directly from your Samsung TV. Not only that, it also already supports some Smart Home Apps like Amazon Alexa, Google Home, Smart Thing, and others. And to make navigation further easier, it has built-in voice navigation that supported by Samsung’s Bixby.

Remote

Samsung TM 2050C

As their controller, they are equipped with Samsung Smart Controller, which is TM 2050C. Their remote is similar to previous model found on the Q70R, Q80R and other last year models, but with a bit change on a button. If in last year, there is shortcut to Hulu, in this model, its function is changed to Samsung TV Plus. Except that, there is no change. As we have known, their remote is small and only has few buttons. Nevertheless, their remote has a lot of smart features and built-in microphone for voice navigation. Its remote also has a feature called OneRemote that allow it can act as universal remote. The excellently, not only devices that supports HDMI CEC that can be controlled by this remote, but also other devices that don’t support HDMI CEC. But even so, to control non CEC device, it need direct line of sight because it works over IR.

Samsung Q80T vs Q70T Performance

Black Level and Contrast Ratio

Samsung Q70T has higher native contrast ratio than the Q80T. If the native contrast ratio of the Samsung Q70T is around 3000:1, the native contrast ratio of the Q70T is around 7000:1. This may be caused the use of Ultra Viewing Angle optical layer reduce the native contrast ratio of the Q80T. This certainly makes the Q70T can produce deeper black than the Q80T. But even so, this is just not about native contrast ratio. Even though the Q80T has lower native contrast ratio, but it has local dimming that can boost its contrast ratio to around 4000:1. Not only that, local dimming of the Q80T is also able to reduce intense blooming around bright object, so some highlights like subtitle in films can be handled better than the Q70T. On the other hand, although Q70T has higher native contrast ratio but it doesn’t have any local dimming feature that can improve its dark room performance. Meanwhile, to minimize intense blooming, it exploits its frame dimming by lowering its peak brightness in small window.

Ignoring their difference, black produced by them is deep enough to show black of image looks really black. Their black level is also deep enough to reveal details in shadow of HDR images so looks excellently. Overall, the Samsung Q70T may be able to produce deeper black, but without local dimming feature, its performance in a dark room is not as good as the Q80T.

Winner: Q70T

Peak Brightness

Both Samsung Q70T and Q80T have good SDR peak brightness and overall, their SDR peak brightness is not much different. But even so, their characteristic in producing peak brightness at each window is different. Since the Q70T doesn’t have local dimming, its peak brightness is relatively consistent at any windows size, which is around 500 nits. But in 2% window (2% of the screen is white while the rest is black), its peak brightness is lowered by its frame dimming to around 250 nits. On the other hand, the peak brightness of the Q80T is depending on the window sizes. The brightest peak brightness is reached at 10 % window, which is around 700 nits and the lower peak brightness is reached on 100% window, which is around 400 nits. Nevertheless, ignoring their difference, peak brightness of the Samsung Q80T and Q70T is actually bright enough to fight the glare, allow you to watch TV in most bright room without any serious issue.

Meanwhile, when they come with HDR content, peak brightness of the Q80T is better than the Q70T. The peak brightness of the Q70T behaves the same way as when displaying SDR content, where its peak brightness is relatively consistent at any windows sizes at around 500 nits, except 2% windows is at around 250 nits. Its peak brightness may bright enough to show SDR content fairly bright in most bright rooms, but it is not bright enough to show HDR content they should be. Let alone its peak brightness at 2% window is much darker, this makes it cannot show HDR images with small highlight that pops. On the screen of the Q70T, HDR images don’t look much different from SDR content.

Meanwhile, the Q80T has better HDR peak brightness where with real content, it can hit around 700 nits. Just like with SDR content, on 10% window, it can hit brighter than 700 nits that means HDR images can be shown with highlight pop. Meanwhile, on 100% window, its peak brightness drops to around 450 nits. This means, the Q80T can show HDR images with good peak brightness with highlight pops, particularly in a dark to moderately-lit room. However, since its peak brightness is still less than 1000 nits, it certainly cannot show HDR images as bright as the target 1000-4000 nits intended by the content creator.

Winner: Q80T

Color Performance

Both Samsung Q70T and Q80T have great color gamut. This is inseparable from the role of the quantum dot technology on their panel. In DCI P3 uv color space, their color gamut is almost similar where their color gamut can cover around 92% of color space. But even so, in DCI P3 xy, the color gamut of the Q80T is a bit better. Color gamut of the Q80T can cover around 88% of color space while the Q70T cover around 85%. Nevertheless, even though the Q80T is a bit better, but their difference is not too significant and overall, their color gamut is equally great. The result, HDR images can be displayed colorfully on their screen.

While their color gamut of the Samsung Q80T and Q70T is almost similar, color volume of the Q80T is better than the Q70T. This is more due to the Q80T has higher peak brightness and local dimming feature that can expand its color gamut. But even so, separated from their difference, they both can produce deep dark colors fairly well. Additionally, they both also can produce their wide color gamut at their entire brightness range. But just like other LED TVs, they both cannot produce very bright blues. Combine to their wide color gamut makes colors of HDR images can be fairly accurate on their screen.

In addition to they both have great color gamut, they both also have excellent color gradient. When showing 10 bit content like HDR images, color gradient of images displayed on their screen looks very smooth with only minor banding that should not be noticeable. Nevertheless, if you feel banding still bother you, you can enable “Noise Reduction” to remove banding. But keep in mind, enabling this feature can cause the image in certain scenes lose some fine details.

Winner: Q80T

Side Viewing Angle

As we have mentioned above, the Samsung Q80T has an optical layer called “Ultra Viewing Angle” that can improve its side viewing angle coverage. As the result, side viewing angle of the Q80T is better than most LED TVs with VA panel including Q70T, but still worse than IPS panel.  If on the screen of the Q70T, black level will look start to rise at around 15 degrees off center and front, on the screen of the Q70T, black level can be maintained up to 70 degrees. Additionally, the panel of the Q80T also can better maintain color and brightness than the Q70T. On the screen of the screen of the Q70T, color will look washed out started at around 25 degrees, on the screen of the Q80T, color can be maintained at up to 40 degrees. As well as peak brightness, the Q70T will lose its peak brightness at around 30 degrees, the Q80T can maintain at up to around 45 degrees.  The result, when viewed from the side, the picture displayed on the screen of the Q80T will look much better than on the screen of the Q70T.

Winner: Q70T

Motion Handling

Even though they both are supported by the same Motion Rate 240 Hz technology, but the pixel response time of the Q80T is much faster than the Q70T. If pixel response time of the Q80T is around 10 ms, the pixel response time of the Q70T is around 15 ms. The result, when playing fast paced content, fast scenes looks clearer and smoother on the screen of the Q80T than Q70T. Nevertheless, although not as smooth as Q80T, fast scene also still looks smooth on the screen of the Q70T. Following fast moving object, there is only a short ghosting trail that should not be noticeable for most people. Blur that may be still visible is more caused by persistence or their backlight flicker.

Just we have mentioned above, both Samsung Q80T and Q70T have an optional BFI (Black Frame Insertion) mode. It is very helpful to make motion smoother, particularly when they are playing 60 fps content like sports or video games. But keep in mind, enabling BFI mode may make motion looks smoother, but on the other hand, since their backlight flicker change to 60 Hz, this may cause their backlight flicker is noticeable for some certain people, particularly for them who sensitive to flicker.

Meanwhile, when playing 24 movies, they both can do a great job when handling judder. No matter the source is native 24p content like DVD or Blu Ray Movies, via 60i signal like movies from satellite TV, via 60p signal like movies from streaming devices, or movies from native apps like YouTube, Netflix, and others, they both can show them with judder-free. To remove the judder, On Q80T, you just need set “Picture Clarity” to “Custom”, “Blur Reduction” to 10 for 60 fps content, and “Judder Reduction” to 10 for 30 fps content. Meanwhile on Q70T, you just need set “Picture Clarity” to “On”, “Remove Blur” to 10 for 60 fps content, and “DeJudder” to 10 for 30 fps content.

Winner: Q80T

Input Lags

The input lags of the Samsung Q70T and Q80T in PC and Game mode are equally great. With 60 fps content, their input lags are around 10 ms in almost all resolution whether at 1080p, 1440p, 4K, 4K with HDR and others.  This certainly makes them are very responsive when used for playing 60 fps games, even for fast paced games that required fast reflexes. Their input lags at 120 Hz are even greater, which is around 6 ms at both 1080p and 1440p resolution. But keep in mind, they both don’t support 4K @ 120 Hz, so there is no data for that. Furthermore, their input lags in VRR mode are also excellent, which is around 7 ms at 1080p and 1440p resolution and around 15 ms at 4K resolution. With their excellent input lags, regardless you are playing 60 fps or 120 fps games, casual or fast paced games, with HDR or not HDR, 1080p, 1440p, or 4K games, they are equally very responsive.

Conclusion

For Watching Movies

Both of the Samsung Q80T and Q70T are equally good TVs for watching movies in a dark room. They both have deep black and combine to their excellent black uniformity make shadow details of HDR images still look excellently in a dark room. Additionally, they both also have great 24p judder handling, allow you to watch movies with judder-free. Combination of good peak brightness, excellent color gradient, white color gamut and deep dark certainly makes any movies looks excellently on their screen. Meanwhile, comes with local dimming feature makes the Q80T is better than the Q70T, particularly when they are showing small highlights like subtitle. On the screen of the Q70T, blooming is more noticeable than on the screen of the Q80T that has local dimming feature.

Winner: Q80T

For Watching Sports

Actually, both of the Samsung Q70T and Q80T are also good TVs for watching sports. Combination of their good SDR peak brightness and good reflection handling allows you to watch sports in most bright room without serious issues. Nevertheless, The Q80T is a bit better since it has faster pixel response time than the Q70T. Additionally, side viewing angle is also an advantage of the Q80T, particularly when you are watching a big game with a group of your family of friend. Since the side viewing angle coverage of the Q70T is poor, when you are watching a big game with a group of your family or friend, some of you may not get the best viewing. On the other hand, with better side viewing angle coverage, this ensures all of you will get the best viewing when watching a big game.

Winner: Q80T

Video Games

When used for playing video games, their performance is also very satisfactory. They both have good pixel response time that makes fast paced games look smoothly on their screen. Additionally, they both also have excellent input lags that allow you to play game responsively. Not only that, the support of VRR technology, which are FreeSync and HDMI VRR will improve your experience in playing game with almost no screen tearing. Meanwhile, has faster pixel response time makes the Q80T is a bit superior to Q70T when used for playing video games, particularly for fast paced games.

Winner: Q80T

HDR Performance

HDR Performance of the Q80T is better than the Q70T. They both may have deep black that allows them can show shadow details excellently, but with local dimming feature, blooming can be minimized better, so highlight in a dark scene can be shown better on its screen than on the screen of the Q70T. Additionally, its local dimming also makes colors of HDR images can be shown better than the Samsung Q70T, albeit they have almost similar color gamut.  And lastly, that makes their HDR Performance is different is about their peak brightness. Peak brightness of the Q70T may be bright enough for SDR content in most bright room, but for HDR content, this will not give significant added value over SDR content.  Let alone, its peak brightness in very small windows is much darker, makes HDR images cannot be shown with highlights that pop. On the other hand, HDR peak brightness of the Q80T is better.  Although it is not able to show HDR images as bright as 1000-4000 nits of target, but at least, it is able to show HDR images with highlight pops.

Winner: Q80T

Summary

Overall, the Samsung Q80T is significantly better than the Q70T. They may be supported by the same images processor, but some other aspects makes its performance is better.  The Samsung Q70T may have higher native contrast ratio that makes it can produce deeper black, but the Q80T has local dimming performance that makes its dark room performance is better. Additionally, the Q80T also has much wider viewing angle, better color accuracy, and can get brighter in HDR content.  And lastly, the pixel response time of the Q80T is also faster, makes motion look smoother on its screen than on the Q70T. So, which is a better choice? If your main consideration in buying TV is performance or picture quality, of course the Q80T is better. But keep in mind, with the same screen size, it is also price more expensive than the Q70T. On the other hand, even though not as good as the Q80T, the Samsung Q70T has cheaper price and compare to other TVs in its class, its picture quality performance and picture quality is also great. Now, the decision comes back to you according to your budget and own preferences.
