AMD Radeon RX 6800 XT review: the redness in the high-end PC segment has never been so bold

A new look at AMD graphics cards

The Radeon RX 6800 XT graphics card in the article is the reference version (reference card also known as the ref card), which carries the original design from AMD. The company has abandoned the squirrel cage-type heatsink design that has many disadvantages, replacing it with a pit system of three cooling fans that significantly improves performance and is as eye-catching as commercial card products.

The small pluses but show the sophistication of AMD as the backplate has been made of solid metal, the power supply port is still the popular 8-pin type instead of the strange 12-pin type as in the same product. prime. The appearance of USB-C next to two DisplayPort 1.4 and HDMI 2.0 ports is another great asset when not only outputting signals to this connected monitor easily, but also ready for a multi-dimensional visual experience. through virtual reality glasses.

The positive changes and genuine equipment in the reference card version of the Radeon RX 6800 XT will make an important contribution to the end users get better graphics card model. The tuning of this card model helps third-party companies somewhat reduce the cost and time to develop the commercial version. From there you can expect an even more pleasant price tag, especially given the announced number of the RX 6800 XT from AMD is already $ 50 cheaper than its rival.

New technology series

As the 2nd generation of RDNA architecture, the AMD Radeon RX 6800 XT delivers an impressive range of innovations. Still manufactured using 7nm process but in RDNA2, the processing clock can be 1.3 times higher in the same power consumption, the performance / watt index increases by 54% compared to the first generation.

In addition, AMD has introduced many new technologies to make an explosion of performance and experience in this generation of GPU. The first is that the RX 6000 series officially supports Ray Tracing at the hardware level. By integrating directly into each of the processing units (CU) a Ray Tracing processing unit, real-time computation and image processing promises to be impressive in optimized applications / games. . In the long run, this Ray Tracing approach offers a mutual advantage for “red team” users as game makers bring the technology to cross-platform games from Xbox X, PS5 to PC.

In addition, other improvements such as Infinity Cache provide large capacity caching to increase the computational efficiency of the GPU, Variable Rate Shading (VRS) improves rendering capabilities, FidelityFX Anti-Lag reduces signal latency. , … AMD is currently developing Super Resolution to significantly improve ray tracing performance and will soon update in the new GPU line in the near future.

Smart Access Memory (SAM) is equipped with “private parcel” of RX 6000 series GPU users on Ryzen 5000 series systems, motherboard X570 / B550 when increasing bandwidth access VGA memory, reducing bottleneck phenomenon, this can increase overall performance by up to 11%.

Red in the high-performance segment is “bold” than ever

Flashy of specs and excitement at the experience, that’s exactly what you feel in high-end graphics cards from AMD. Following the momentum after the blockbuster Ryzen 5000 series made fans admire, you can now own a high-end system “red” from the CPU to the GPU like the PC used for evaluation in the article. Test configurations include Ryzen 7 5800X CPU, Radeon RX 6800 XT GPU, 2x8GB of 3,200MHz DDR4 RAM, 480GB SSD M2 and 2K display.

The performance of the most anticipated RX 6800 XT is probably in the games. To produce enough land to unleash its full power will need AAA games such as Assassin’s Creed: Valhalla, Dirt 5, Borderlands 3 with graphics settings set to maximum with 2K resolution.

The default RX 6800 XT produces enough results that please every hardcore gamer when the average frame rate can reach between 80-100fps. Stability is also convincingly shown when looking at FPS numbers 1% Lowest are well above the 60fps mark. Especially the “full red” combo is empowered with Smart Access Memory technology. All three games recorded similar increases in FPS and 1% Lowest.

The power of high-end graphics cards from AMD is not only attractive to gamers but also impressive enough for professional users … AMD’s strong comeback in recent years is slowly changing people’s perception. use and get better support from software vendors. For example, with the latest Adobe Premiere Pro version 14.6 application, the dedicated PugetBench test includes post-production operations, effects, rendering on 4K & 8K clips, the machine brings red from AMD for the score. Overall on par with the PC system using rival components.

Reference score for 2 PC systems by Puget System

During a multi-hour review in a room with an average temperature of 30 degrees Celsius, the maximum temperature of the RX 6800 XT was around 90 degrees Celsius, a pretty good figure for the reference card model. The system’s stability is also recognized in its compatibility and smooth running of all copyrighted apps and games that have been updated to the latest version. AMD’s attempt to change can be seen in trying to deliver quality drivers to users (the product in our article uses driver version 25.20.14501.18003).

In just a few short years we saw a boom to return to the lead in AMD’s CPU segment with Ryzen processors. And now the same thing is happening with the RX 6000 series GPUs. The powerful breakthrough in performance, technology, and popularity spanning multiple hardware platforms of the RNDA2 architecture give AMD’s new generation of GPUs a huge advantage, including the RX 6800 XT. The red color in the high-end PC segment next time will also be more intense than ever.
