Main Features

The TVs from both series can offer a Multi Voice with two built-in voice assistants: Alexa and Bixby voice assistant. Just like most Samsung TVs from the non-budget range, the models from series 7 and series 8 run on Tizen operating system. It’s much more convenient and faster than Android OS, for example, as it was developed specifically for Samsung Smart TVs.

The QLED TVs from both series use Active Voice Amplifier which automatically increases the volume level in order to silence the background noises. They both also can offer a Multi View feature. It allows you to mirror the screen of your smartphone to the TV and divide TV’s display into two parts to watch two videos simultaneously or browse the web while watching a movie, for example.

They both also boast an Auto Motion Plus feature which is designed to reduce a soap opera effect, making fast motion scenes look smoother. In other words, the picture on the screen changes faster compared to other displays. This feature is very helpful when watching sports programs, action movies, and playing video games.

As for games particularly, both series use either Auto Game Mode or Real Game Enhancer in order to adapt the TV for games. The last one is used in more expensive models, but, to be honest, these technologies are quite similar, and it’s hard to say which one is actually better. However, TVs from series 8 are more suitable for gaming as most of them have 240Hz native refresh rate while TVs from series 7 bring you 120Hz.

Being more advanced, series 8 naturally provides more features compared to series 7. For example, it offers a Q-Symphony that plays the sound from your soundbar and TV’s speakers simultaneously. The Q-Engine optimizes poor-quality content not only to 4K but to HDR as well.

Let’s compare two identical mid-priced TVs from both series, the Samsung UN50RU7100FXZA and the Samsung UN55TU8000FXZA. The first one has quite standard features, such as compatibility with Alexa and Google Assistant, 4K AI Upscaling, and Universal Guide. The second model, in its turn, has two built-in voice assistants and Multi Voice feature, Universal Guide, Auto Game Mode, and 4K AI Upscaling.

So, if you need more advanced features in your TV, you will consider the Samsung UN55TU8000FXZA as a better option in this part of the 7 series vs 8 series Samsung comparison.

Design

First of all, both series offer TVs with a slim, modern design. They have very thin borders around the display (0.55 inches or less) and wide viewing angles, so the picture looks equally good from any angle. They both also have an anti-glare coating. Most of them are VESA mountable. The series 7 has such a range of screen sizes: 43, 50, 55, 58, 65, and 75 inches. The series 8 of TVs of such sizes: 43, 50, 55, 65, 75, and 85 inches.

However, considering the fact that series 8 TVs have thicker profiles. So, if we compare 43-inch models from both series, the Samsung UN43RU7100FXZA and the Samsung UN43TU8000FXZA, the first model appears to be thinner (2.3 inches vs 2.4 inches).

So, if you need a slimmer TV that will look better when mounted on the wall, for example, your choice should fall on the Samsung UN43RU7100FXZA.

Picture Quality

The UHD TVs from either series aren’t very similar. The models from series 7 are plainer. They use simple UHD, HDR, and PurColor technology to enhance brightness. Such TVs are built on 4K UHD processor which upscales non-4K video content to 4K. The UHD TVs from series 8 are more advanced. They are equipped with Crystal UHD which works better in providing a clear and more natural picture. Such TVs work on Crystal Processor 4K that has the same working principle as 4K UHD Processor, but it works faster. The UHD TVs from both series use standard HDR. Series 8 also presents a range of high-end UHD TVs. They use Premium UHD and Dynamic Crystal Color technology which provide a more cinematic picture and reveal more shades of color than other UHD TVs.

The QLED models from both series are based on Quantum Processor 4K. It uses AI to transform content into 4K. Both of them also use an Adaptive Picture technology which automatically regulates the picture brightness for your convenience. The series 7 QLED TVs use Quantum HDR which provides a more expanded color range compared to standard HDR. There is also a Dual LED system for enhanced contrast. A special Quantum Dot Technology makes colors look more lifelike, providing an immersive viewing experience. The QLED TVs from series 8 are much more advanced. They use such innovative technologies as Direct Full Array 8X, Quantum HDR 8X, etc. As a result, TVs from series 8 generally have better contrast and a more vivid, realistic picture.

If we put into comparison two QLED models from both series, the Samsung QN50Q80TAFXZA and the Samsung QN75Q70RAFXZA, there will be no doubt that the first model provides a more clear and lifelike picture.

Sound

Such cinematic audio technologies as Dolby Atmos, Dolby Surround, and DTS are implemented in many TVs from both series. Most TVs from series 8 have 2.1-channel speakers and a sound output of 40W. They also feature an Object Tracking Sound technology which is designed to provide a realistic 3D sound. Meanwhile, TVs from series 7 usually have more simple 20W 2-channel speakers.

Let’s take two 55-inch UHD models from the comparable series. The Samsung UN55NU8000FXZA has 40W 2.1-channel speakers with integrated woofer and Dolby support. The Samsung UN55RU7100FXZA has 2-channel 20W speakers with Dolby support as well.

The Samsung UN55NU8000FXZA speakers win here as they are twice as powerful as those from Samsung UN55RU7100FXZA and have an inbuilt woofer.

  • Smart TV with Bixby Voice: A revolutionary way to help find streaming and live TV shows with a Universal Guide, one remote and voice assistance. Sound Output (RMS):40 Watt

TV Ports

The main difference between the series in this category lies in the number of HDMI ports. In most cases, series 8 provides 4 HDMI inputs while its competitor has 3. Series 7 usually has composite and component video inputs. In terms of other types of connectors, they are identical. As a rule, both series provide TVs with 2 USB ports, Ethernet, digital audio output, RF input for analog sources, etc. For instance, the Samsung QN50Q80TAFXZA has 4 HDMI, 2 USB 2.0 ports, Ethernet, digital audio out, RF input, and RS232C. The Samsung UN50RU7100FXZA features 3 HDMI, 2 USB ports, Ethernet, composite and component video inputs, RF input, digital audio out, RF input, and RS232C.

Since composite and component video inputs are less relevant for modern users than HDMI and USB 2.0 ports, it’s fair to say that the Samsung QN50Q80TAFXZA shows better results in this part of the Samsung series 7 vs 8 comparison.

  • AMBIENT MODE + TM: Blends into your space by turning a blank screen into enticing visuals or at a glance info.

TV Controls

As usual, the control buttons on Samsung TVs bodies find place beneath the front of the TV. However, series 8 is more focused on providing a minimalistic design. This way, the Samsung UN43TU8000FXZA has one multifunctional button that allows you to turn the TV on/off, change channels, volume, or inputs. The Samsung QN75Q70RAFXZA has 5 buttons: select button and arrow buttons that help you access and navigate the menu, change channels, volume, and input, and return to the home menu.

The Samsung QN75Q70RAFXZA appears to be better in this part of the Samsung TV 7 series vs 8 series comparison as its onboard buttons provide wider functionality.

Remote Control

TVs from either series may come with OneRemote or standard remote control. The last one is an old-fashioned remote with 42 buttons and without voice control. OneRemote is a sleek-looking, minimalistic remote control with 12 buttons (including quick-access buttons to Netflix, Amazon Prime Video, and Samsung TV Plus). It provides much simpler control over the TV’s smart features as it’s endowed with voice control and allows communicating with voice assistants. It also works through radio frequency, so you don’t have to direct it to the TV.

Obviously, more expensive and more advanced TVs come with OneRemote and you are more likely to get it when buying the series 8 model. This way, the Samsung UN50RU7100FXZA comes with a standard remote, the Samsung UN43TU8000FXZA kit includes OneRemote.

Thus, the Samsung UN43TU8000FXZA will be a better option if you don’t want to spend extra money on upgrading the remote control of your new TV.

Price

The prices for series 7 models start from around $300 while the TVs from series 8 are offered from around $400. However, as for advanced models, the difference in prices between the series is much more significant. For example, the Samsung UN65RU8000FXZA and the Samsung UN65RU7100FXZA have a double difference in their prices despite the fact that they both are 65-inch UHD TVs.

This way, the Samsung UN65RU7100FXZA wins in the Samsung 7 series vs 8 series price comparison as it’s more budget-friendly.

Samsung 8 Series vs 7 Series: Conclusions

The TVs from both series are able to offer 4K upscaling, Multi Voice, Auto Motion Plus, Active Voice Amplifier, and other common features. However, as it’s obvious from the information explained previously, series 8 is in the winning position in this Samsung 7 series vs 8 series 4K comparison. It gives you more modern features, a more natural picture, and a better sound. Series 7 TVs are cheaper, but can’t offer a lot of such advanced features.
