Samsung RU8000 vs NU8000 Review

Samsung RU8000 is the highest flat model of Samsung’s non QLED TVs that released in 2019. It sits between the Q6FN and RU7100, and in the market, it sits on middle class TV.  It is launched in to market to replace the Samsung NU8000 its predecessor. In the market, they come with the same variant of screen sizes. From the smallest, there is 49 inches (UN49RU8000 vs UN49NU8000), 55 inches (UN55RU8000 vs UN55NU8000), 65 inches (UN65RU8000 vs UN65NU8000), 75 inches (UN75RU8000 vs UN75NU8000), and the largest is 82 inches (UN82RU8000 vs UN82NU8000). But just some models of Samsung’s 2019 lineup, their 49 inch model (UN49RU8000 and UN49NU8000) comes with a bit difference in specs than the bigger size model. Their difference is on their native refresh rate panel where their 49 inch model has native 60 Hz refresh rate panel while the bigger model has native 120 Hz refresh rate panel. Additionally, their 49 inches model also doesn’t support Variable Refresh Rate while the bigger model already supports FreeSync VRR.

The interesting among them, even though the RU8000 is the successor of NU8000, but with the same screen sizes RU8000 is precisely sold cheaper than its predecessor. Now the question, “Is performance of the Samsung RU8000 as the newer model better than the NU8000?

The differences between Samsung RU8000 and NU8000

As we see on the comparison table above, even though the Samsung RU8000 is the successor of the Samsung NU8000, but in specs, the level of its technologies is precisely lower than the successor or even it lacks some technologies in comparison to its predecessor. Some of their differences may not have a significant impact on their performance, but some others have a significant impact. Below are some difference between the Samsung NU8000 and RU8000.

Local Dimming Technology

Local dimming becomes one of the main differences between the Samsung RU8000 and NU8000. They may use the same panel technology, which is VA panel. Additionally, they also use the same backlight technology, which is Edge-lit LED backlight. But even so, as the newer model, Samsung RU8000 precisely lacks local dimming technology in comparison with the NU8000 predecessor. A little much, this certainly will have an impact on their performance, particularly in their contrast, color vibrancy, peak brightness, and their performance in handling blooming. But even so, since the RU8000 has edge-LED lit backlight, can be ascertained, the performance of its local dimming is not as powerful as FALD (Full Array Local Dimming) we found on the series above it like the Q70R, Q80R or higher model.

The Level of Dimming Technology

This is not about the “real” local dimming, but about their software based dimming technology. For this case, the Samsung NU8000 is powered by “Supreme UHD Dimming” while the RU8000 is powered by “UHD Dimming”. We don’t surely know what their differences, but can be ascertained, the level of Supreme UHD Dimming is higher than UHD Dimming.

Depth Enhancing Technology

As we see on comparison table above, the Samsung NU8000 has a depth enhancing technology called “Contrast Enhancer”, while the RU8000 successor lacks this technology. We don’t surely know, whether the RU8000 really lacks this technology or Samsung just doesn’t list this feature as its specs on its official website.

Smart TV Version

Tizen 2019

Samsung RU8000 and NU8000 may runs the same smart TV platform, which is Tizen OS that powered by a quad core processor. But as a newer model, the RU8000 also comes with newer version of Tizen OS which is 2019 version while the NU8000 comes with 2018 version. At a glance, on their user interface, there is almost no difference between these versions. But even so, the 2019 version is faster and more responsive than the older version. Additionally, there are also some additional features offered by the newer version.

Remote Control

As their controller, Samsung NU800 and RU8000 both come with Samsung’s smart controller, but their version is different. Samsung RU8000 comes with the TM1950A models while the NU8000 comes with the TM1850A model. A glance their remote is similar. They have the same button layout, design, material, and also color. But even so, a bit difference between these remotes, the 2019 model has 3 additional buttons dedicated for Amazon, Netflix, and Hulu.

Audio System

As we see on comparison table above, for delivering sound, the Samsung NU8000 is equipped with 2.1 channel speaker system. It has 40 watts of total sound output and also has a built-in woofer for boosting the low frequency or bass. On the other hand, the Samsung RU8000 is only equipped with standard 2.0 channel speaker system with 20 watts of total sound outputs. This means, it doesn’t also have a built-in woofer. This certainly makes the sound delivered by RU8000 is not as steady as the NU8000, particularly in low frequency or bass.

Samsung RU8000 and NU8000 Performance

Contrast and Black Level

The Samsung RU8000 has a bit stronger native contrast ratio than the NU8000. However, their difference actually is not too significant that of course makes the impact resulted is also not too significant. Nevertheless, ignoring their difference, the native contrast ratio of the RU8000 and NU8000 is equally excellent, makes black produced by them looks really black, even when they are set in a dark room. The result, dark scene looks excellent on their screen, even in a dark room. Black produced by both NU800 and RU8000 actually is also deep enough to show shadow details of HDR images so looks excellently.  But even so, lacks of local dimming makes dark scene displayed on the screen of RU8000 doesn’t look as good as NU8000. The performance of the local diming of NU8000 may be not as powerful as FALD in boosting contrast ratio, but at least, its local dimming can minimize blooming, particularly when it is showing a highlight in a dark scene.  Meanwhile, without local dimming, when RU8000 showing small highlight in a dark scene, some unwanted adjacent light or blooming are visible at everywhere, particularly around small bright objects. So, when they are showing small highlight in a dark scene, blooming may be still visible on the screen of NU8000, but not as many as on the screen RU8000.  Overall, thanks to their deep black level, their performance in a dark room can be said excellent in their price range.

Winner: NU8000

Peak Brightness

In term of peak brightness, as a newer model, performance of Samsung RU8000 is precisely worse than the NU8000 predecessor. Whether it is playing SDR or HDR content, the peak brightness of the RU8000 is similar and very consistent regardless of the content it shows, except 2% windows that is dimmed by CE dimming feature. Peak brightness reached by RU8000 is around 350 nits where this actually is fairly bright to fight the glare. But as we have mentioned, when it is showing a small highlight around 2% of the scene, its peak brightness is dimmed to below 200 nits by TV’s CE dimming system. For SDR content, peak brightness of RU8000 might be fairly good, makes it suitable for most bright rooms. But for HDR content, its peak brightness is still far from what required, even still under expectation. As we know, to show HDR images like the intended, a HDR TV should have peak brightness brighter than 1000 nits. Meanwhile, with around 350 nits of peak brightness, the highlight will not look out standing and you will not get a lot of benefit offered by HDR over SDR content, particularly in showing highlight or bright scene.

On the other hand, the Samsung NU8000 can brighter than RU8000. With real SDR content, its peak brightness is around 500 nits where it is bright enough to overcome the glare in most bright rooms. Just like the RU8000, its peak brightness tends to be consistent regardless the size of bright object, except when it showing around bright area around 2% of screen.  The difference is when they are showing a bright object around 2% of screen, if on RU8000, its peak brightness is by CE dimming feature to below 200 nit, on the screen of NU8000, its peak brightness is even brighter, which is around 700 nits. Meanwhile, with HDR contents, the Samsung NU8000 can get a bit brighter, makes HDR images can be shown fairly bright. It may not be able to show HDR images at 1000 – 4000 nits of brightness range intended by the content creator, but at least, HDR images looks fairly bright on its screen and bright enough for almost all rooms. With HDR content, NU8000 can also get brighter than RU8000.

Winner: NU8000

Color Performance

Both Samsung RU8000 and NU8000 can display a wide color gamut. But even so, as newer model, the color gamut of RU8000 is precisely a bit worse than NU8000.If color gamut of the Samsung NU8000 can cover around 92% of DCI P3 uv or around 86% of DCI P3 xy, the color gamut of RU8000 only can cover around 90% of DCI P3 uv or around 84% of DCI P3 xy. The result, NU8000 can show some certain colors more accurate than RU8000. And since the color gamut that recommend for showing HDR images fully like the intended is 90% of DCI P3, although not as good as QLED TV lineup, a least, HDR images still looks colorful on its screen. Additionally, the color volume of NU8000 is also a bit better. But even so, this is more caused it has a bit wider color gamut than RU8000. But in general, they both can display most of its color gamut at their entire brightness range fairly well, except very bright blues. Overall, for their price range, their color reproduction is equally excellent. But since NU8000 has a bit wider color gamut and better color volume, on some certain colors, it can show them better than RU8000.

Dynamic Crystal Color

Not just in term of color gamut and color volume NU8000 is superior, in term of color gradient, Samsung NU8000 is also superior to RU8000. On some certain shades, NU8000 can show them smoother than RU8000, particularly in dark green and reds. But even so, ignoring their difference, overall, they both have good color banding. Most of shades of colors can be shown fairly smooth on their screen. Some color bandings may still be visible in certain colors, particularly in darker colors, but this should not be a problem for normal usage. But even so, if you find the bandings bothering you, you can set the “Digital Clean View” to “Auto” to eliminate most of them. But on the other hand, in certain scenes, this will makes the images lose some fine details.

Winner: NU8000

Side Viewing Angle

As usual of an LED TVs with VA Panel technology, both Samsung RU8000 and NU8000 also have poor side viewing angle. This means, when viewed from the side, the picture displayed on their screen looks less accurate, even from small angle off center. You need to know, started less than 25 degrees off center and front, color will shift and brightness will drop. The black level degradation is even more severe where started at around 15 degrees, their black level will fade. And from the wider angle you watch the TV, the picture displayed on their screen will look more inaccurate. This will be a problem when you watch TV with a group of your family or friend, particularly for you who sit further off center. If you are bothered with their poor viewing angle, an LED TVs with IPS panel will be a good solution for you.

Winner: Draw

Motion Handling

As we know, the most major aspect that has a significant impact on the TV’s performance in handling motion blur is pixel response time. The lower pixel response time of the TV, its performance in handling motion blur is better.  Samsung RU8000 may have a bit lower pixel response time than NU8000, but their difference is not so significant and doesn’t have a significant impact to the picture produced. However, ignoring their difference, their pixel response time actually is equally excellent, which is less than 15 ms. The result, when they are playing fast moving images like fast movies, fast games or sports, the picture displayed on their screen looks very smooth without a lot of visible motion blur. Following fast moving object, there is only a short ghosting trail where most people may not notice this much. Meanwhile, the blur that may be visible is more due to backlight flicker.

Low pixel response time

Meanwhile, for dimming their backlight, both Samsung NU8000 and RU8000 use PWM (Pulse Width Modulation) dimming system. Their dimming frequency is depending on the setting, but their highest dimming frequency is also same, which is 240 Hz and this will be reached when they are set on “Movie” mode and the “Auto Motion Plus” is disabled. With high dimming frequency, this will make the backlight flicker is almost no visible, but on the other hand, this will makes some unwanted duplications. But even so, their dimming frequency also can be changed by changing the setting. As example, even though you stills set them in “Movie” mode, but if the “Auto Motion Plus” is set to “Custom” or Auto”, this will makes their dimming frequency drops to 120 Hz. Additionally, enabling “Game” mode also makes their dimming frequency is always 120 Hz.

As we have mentioned above, the blur that may be visible particularly when they are playing 60 fps content like sports or video games is more due to backlight flicker. To overcome this issue, both Samsung RU8000 and NU8000 have an optional BFI (Black Frame Insertion) mode called “LED Clear Motion”.  You can find this feature on the “Auto Motion Plus” Menu.  By enabling “LED Clear Motion”, this will make its dimming frequency drops to 60 Hz and this will very helpful to reduce blurs that caused by backlight flicker or persistence, particularly when you are playing 60 fps content. But on the other hand, since their dimming frequency change to lower, this will makes the backlight flicker is more noticeable. If you feel the backlight flicker bothersome to you, you can disable this feature. Otherwise, if you feel bothered by persistence blur, you can enable this feature.

One of the advantages of Samsung’s TVs including NU8000 and RU8000 is that they are already support FreeSync Variable Refresh Rate. By default, they both have native 120 Hz refresh rate panel. But it does not rule out the possibility that their refresh rate panel change depending on the input device’s output. On 4k resolution, their refresh rate can change between 48 Hz to 60Hz while on 1080p resolution, their refresh rate can change between 20 Hz to 120 Hz. This will be very helpful to remove the screen tearing when you are playing a game with compatible game consoles like Xbox One or others. But keep in mind, this is only for the 55 inches model or bigger while for the 49 inches model or smaller, they don’t support VRR.

When playing 24p movies, Samsung RU8000 can do a better job than NU8000, particularly for 24p movies via 60i signals like movies from satellite TV. With this source type, the RU8000 can show it with judder-free while the NU8000 cannot remove the judder completely. But for other sources, whether it is native 24p videos like Blu-Ray or DVD movies, 24p movies via 60p signal like movies from streaming devices or PC, movies from native apps like Netflix, Amazon Videos, and others, their performance is similar and they both can show them with judder-free. For removing the judder, the “Auto Motion Plus” must be set to “Custom” and both the “Judder reduction” and “Blur Reduction” must be set to “0”.

Winner: RU8000


The Samsung NU8000 and RU8000 are equipped with the same inputs/outputs. They both have 4HDMI ports. But even so, the HDMI ports of Samsung RU8000 supports a bit more type of inputs than NU8000. At 60 Hz, they both support most type of inputs including 1080p, 1080p @4:4:4, 4K, and 4K @4:4:4. Bu even so, NU8000 doesn’t support 1440p resolution at 60 Hz while the RU8000 already support this input. At 120 Hz, the input types which supported by them are similar where they both support 1080p, 1440p and 4 resolution.  In addition to HDMI ports, they both also have 2 USB ports (USB 2.0), 1 RF In (Tuner In), Digital Audio Out (Optical), and 1 Ethernet port. The both don’t have Component In and Composite In.

In term of their input lags in PC and Game, which has a better input lags between them is depending on the sources. At 60 Hz, RU8000 has a bit better input lags than NU8000. Regardless the resolution, the input lags of NU8000 is around 18 ms while the input lags of RU8000 is around 15 ms. Meanwhile, at 120 Hz, the input lags of the Samsung NU8000 is better than RU8000. If the input lags of NU8000 are around 10 ms at both 1080p and 1440 resolution, the input lags of the Samsung RU8000 are higher. At 1080p resolution, its input lag is around 16 ms while at 1440p resolution, its input lags is around 20 ms.  Meanwhile, with VRR, their input lags are similar where at 1080p and 1440p, their input lags are around 15 ms while at 4K resolution, its input lags is around 15 ms. But ignoring their differences, their input lags actually are equally excellent. No matter you are playing 4K or 1080p games, casual or fast paced games, with HDR or not, they are very responsive.

Winner: RU8000

As we have discussed a lot above, although Samsung RU8000 is the successor of NU8000, buts its picture quality is not better than the predecessor. In term of contrast and black level, the RU8000 actually has a bit stronger native contrast ratio that makes it can produce deeper black than the NU8000 predecessor. But it lacks local diming that certainly makes its dark room performance is not as good as the predecessor, particularly in minimizing blooming that may be visible. Additionally, peak brightness of the RU8000 is also not as bright as NU8000, makes its picture quality is not as consistent as NU8000 in most bright rooms. Additionally, the limited peak brightness also makes HDR performance of RU8000 is not as good as the NU8000 predecessor.  Not only that, even though it also already supports wide color gamut, but the color gamut of RU8000 is also not as wide as the NU8000. Overall, the picture produced by Samsung NU8000 is better than RU8000.

Nevertheless, not on all factors the performance of Samsung RU8000 is worse than the predecessor. It has a bit better pixel response time that makes its performance in handling motion blur is also a bit better. Additionally, the RU8000 also supports more input types and in general, its input lags are better than NU8000. Not only that, the smart TV performance of RU8000 is also faster and more responsive than NU8000.

So, which is a better choice between them? Keep in mind, although the Samsung RU8000 is a newer model and its overall performance is also not as good as the predecessor, but in almost all screen sizes, its price is not also more expensive than the predecessor. Except the 82 inches model, the Samsung NU8000 as an older model is even priced hundred dollars more expensive than RU8000. Now, the decision comes back to you according to your own preferences and budget.
