AMD Radeon RX 6800 XT PCIe 4.0 Gaming Graphics Card Review

AMD_Radeon_RX_6800_XT_Gaming_Graphics_Card_Review

The AMD Radeon RX 6800 XT is AMD’s first Graphics Card in years that actually challenge Nvidia in the high end. However, working here does not remove Nvidia from her throne, especially in today’s DX12 games.

AMD Radeon RX 6800 XT is AMD’s biggest return to the high GPU market. This impressive graphics card takes even Nvidia’s GeForce RTX 3080 with compatible performance, performing better on some games – like the Resident Evil Village at 1440p without tracking the ray – while worse than others while offering a less attractive price. Finally, AMD now has a different and more attractive approach in its hands-on Nvidia’s heavy hitter.

With the new AMD Radeon RX 6800 XT, gamers get 4K game power and advanced features like ray track for $ 649 (possibly £ 649, AU $ 960). It means an affordable 4K playback option for those who want to save a few buckets. It also means that choosing the best 4K graphics card to play has never been this difficult since 4K games first came to the forefront.

Nvidia may not be dethroned, but we are also expecting more gamers, especially those with budget experience, to rely on the AMD Radeon RX 6800 XT.

Price & Availability

The AMD Radeon RX 6800 XT is available on November 18, starting at $ 649 (approximately £ 649, AU $ 960), with the price going up from there with the rear version of the graphics card. This is less than the $ 699 (£ 649, approximately AU $ 960) Nvidia GeForce RTX 3080.

What kind of absorbing this AMD Radeon RX 6800 XT, however, is the low-end RX 6800, which is a bit slow, but comes at a low price of $ 579 (about £ 440, OR $ 800). You pay 12% more with a graphics card that is between 5-10% faster – than the numbers don’t add up.

This makes it difficult to recommend the Radeon RX 6800 XT in terms of the price range. Either that, or it just makes the Radeon RX 6800 look so important – which is exactly what happened with the Radeon RX 5700 XT and Radeon RX 5700 when those started in July 2019.

Features & Chipset

The AMD Radeon RX 6800 XT is based on the design of Team Red’s RDNA 2, which is based on a 7nm (nanometer) production process. Instead of reducing deaths, AMD has worked on some new features and improved efficiency, making these graphics cards more powerful than ever.

The biggest one is the new Infinity Cache, which is very important considering that the Radeon RX 6800 XT uses 16GB of GDDR6 memory, rather than the GDDR6X memory available on the Nvidia GeForce RTX 3080 and RTX 3090.

AMD_Radeon_RX_6800_XT_Gaming_Graphics_Card_Review

Infinity Cache is basically 128MB of the global archive, certified by AMD to be 3.25x faster than GDDR6 VRAM on a 256-bit bus. This helps feed data from a large 16GB VRAM pool to a GPU, and this combination of fast storage and GDDR6 memory results in 2.4x more bandwidth per watt than VRAM will be able to gain on its own. This helps to reduce the gap that AMD could otherwise find if it contradicted the GDDR6X memory on Nvidia class flagship cards.

Another great addition to the architecture is the Ray Accelerators which is directly related to DirectX 12. There is one of the 72 Compute Units, which allows the AMD Radeon RX 6800 XT to be able to manage real-time tracking in the play frame. We’ll get into how they work later, but expect performance to improve as AMD drivers grow – like the improvements seen by Nvidia’s RTX cards throughout the life of Turing cards.

With the exception of the new Ray Accelerators, each Compute Unit (CU) is listed as the first RDNA card. Each CU has 64 Stream Processors (SPs), a total of 4,608 SPs on the Radeon RX 6800 XT. Of course, because we have not seen a process decline, this comes with very high mortality, with 26.8 billion transistors across the 519mm² die.

AMD_Radeon_RX_6800_XT_Gaming_Graphics_Card_Review

This larger death is accompanied by a higher clock speed, too. The Radeon RX 6800 XT has a Game Clock of 2,015MHz and a Boost Clock of up to 2,250MHz. Game Clock is something you’ll probably see most of the time while playing games, and Boost Clock is basically how fast it can go up to huge explosive loads, instead of continuous loads like the best PC games.

With more die space and higher clock speeds, power consumption is obviously increasing sharply. The AMD Radeon RX 6800 XT is rated at 300W, but we have never seen the power of the ASIC (total card-drawn value) exceed 294W. And, most of the time in our tests, our MSI Afterburner overlay reported only between 230-250W games. That means there is too much room for this graphics card to press over.

Hopefully the new VBIOS (VGA BIOS) will be released, which will make the 6800 XT extend even further allowing it to truly reflect its RTX 3080. But without the box when it is released, it is not healthy.

Fortunately, that means temperatures remain low. In all of our tests, we recorded a maximum temperature of 78 ° C, which is much lower than the Radeon RX 6800 cut.

The hotspot temperature, which simply reports that the hottest half of mortality, is as high as 114 ° C high, slightly above 110 ° C recommended by AMD to be within the operation. It did not cause a hot explosion, but be aware that when you look at the temperatures, you may see very high numbers.

Most interestingly though, the Radeon RX 6800 XT is actually a GPU type installed inside the Xbox Series X and PS5. This could mean that games will be easily developed for this graphics card for the next generation of comfort. The benefits of this are demonstrated in games such as the Assassins Creed Odyssey and Far Cry 5, which are not next-generation games but are designed specifically for AMD hardware, and show how effective that functionality can be.

With the Radeon RX 6800 series, AMD brings two optional features to the table, which can help maximize performance. Both Smart Access Memory (SAM) and Rage Mode can help increase performance but return to expectations.

Rage mode is actually overulsive-sanctioned versions because they will not leave your warranty. Or, if you go into Radeon software to enable it, it will tell you that you are confusing arcane settings by risking it – don’t worry, if you use one of the AMD presets, you don’t have to worry about your warranty.

We tested Rage Mode in our 3DMark tests, and it actually led to lower scores – even though it was in error.

SAM is a completely different beast, however. Depending on AMD, this will result in an additional 10% performance, but it does require a combination of your BIOS, not to mention the latest AMD processors and motherboards. You will have to disable CSM, which means some users will have to install Windows 10 from scratch if they do not have UEFI compatible installation, then go into advanced settings and enable Above 4G Decoding and Re-Size BAR Support.

Because of the incredible complexity, we do not recommend anyone other than the very tech-savvy to play with this feature, so we have not tested this review. We’ll take a closer look at it later, though.

When it comes to software support, AMD still offers the same supporting features as they are temporarily now, led by Contrast Adaptive Sharpening (CAS) and Radeon Boost. The latter is especially useful for competing archery players, as it will reduce back-to-back resolution during fast-moving speeds, increasing the frame.

But for now, AMD has no real answer to DLSS, Nvidia Broadcast, or RTX I / O. DLSS and RTX I / O may be surprisingly important for the next generation of games, especially if developers learn to make the most of what SSDs do. on PS5 and Xbox Series X.

Design

Because this is the most powerful graphics card AMD has released in years, it had to rethink its cool. The cooling style of the blower in the Radeon RX 5700 XT would not only cut it to the graphics card for this feature, so AMD has opted for the 2.5-slot fan option three times. That’s why temperatures are always maintained under the default settings, and if you want to get into something like the MSI Afterburner, you can get the best temperatures in it by swinging and turning this fan.

There is also good availability of results on the Radeon RX 6800. You get two DisplayPorts, one HDMI and one USB-C, which should clearly integrate any modern display on the market. Thankfully, AMD did not abandon USB-C as did Nvidia. For power, there are two power-pin connectors that connect to the back of the card.

The AMD Radeon RX 6800 XT looks very much like the product of capital-g Gaming. The side of the graphics card, which you’ll actually see when it’s installed on your PC, is all black with a red color and the Radeon logo in white text – red-light text, obviously.

The front of the graphics card is silver surrounded by three fans, each with an ‘R’ symbol, representing Radeon. In the background, that silver is wide, and it leaves behind a GPU exposed on the backplate, something that doesn’t exactly sound “premium”, but in the end, it doesn’t matter much.

Some people will definitely find the divisive design of the AMD Radeon RX 6800 XT, especially if the black and red gaming art expires in 2020. PC cases these days probably have a side panel of glass, so a graphics card that looks like it came out straight in 2005 is a hard pill to swallow for anyone who wants to show their strength. This will depend entirely on your taste, however, and it probably won’t be as important to most people.

of AMD Radeon RX 6800 XT is a complex issue. There are some situations where it can wipe the floor with the RTX 3080, but most of the time, and it is likely to go further, it has a very tough matchup against Nvidia’s flagship.
Where the Radeon RX 6800 XT is stronger in DirectX 11. For example, in the 3DMark Fire Strike Ultra test, and the DX11 test for 4K performance, the RX 6800 XT adds 12,209 points to RTX 3080’s 11,034. That’s a 10% gain for AMD performance at the same price point.

There are other games where this difference is shown, too. In Grand Theft Auto V in 4K, the Radeon RX 6800 XT is almost 8% faster than the RTX 3080, and even 9% faster on Assassins Creed: Odyssey. However, that is not the same story across the board.

The Nvidia GeForce RTX 3080 beats the AMD Radeon RX 6800 XT with a whopping 12% off 4K with ray tracing off. Also, when you open the ray track, that difference extends to 34%. That radiation effect? That with DLSS is disabled. If you open DLSS with GeForce RTX 3080, you can get 65 fps in 4K with enabled ray tracing, from 47 fps on the same card without Nvidia’s AI enhancement technology. Suppose AMD needs a sensible response from DLSS if it wants to be truly competitive with Nvidia’s radiation tracking because it is clearly unable to solidify its approach to RT’s robust performance.

This is also reflected in the experiments conducted with 3DMark Port Royal. In this radiation-focused test, AMD whiffs hard, hitting 8,541 points on RTX 3080’s 11,344, a 33% difference. When it comes to tracking ray, Nvidia is just ahead of AMD, and there is no way around that. But, hey, at least the AMD Radeon RX 6800 XT supports tech, you’ll want to play at 1440p if you want the RT enabled.

All that is said, however, is that it is amazing that AMD is able to compete in this segment of the market. It’s been years since AMD has had this GPU level, and we’re excited to welcome it back to the fold. It’s important to remember that Nvidia didn’t beat Intel after one generation of Zen – it took a while.

If AMD is able to continue to press its high-quality graphics and improve performance as the 6800 XT upgrades to the 5700 XT just a year later, we think Nvidia could be sweating. This is not a graphics card that guides Nvidia’s performance, but it’s a graphics card that shows how much AMD is back in the game, and we’re very excited to see what the next generation of RDNA has to offer.

We even asked AMD, and he told us that he “expects gamers to see the powerful performance from the graphics cards of the Radeon RX 6800 Series in modern games”. So, we guess we’ll wait and see.

Buy it when …

You play a lot of DX11 Games
The AMD Radeon RX 6800 XT is very powerful in DirectX 11 games such as Assassins Creed Odyssey and Grand Theft Auto V. If your destination game is based on this API, you are likely to get stronger performance here than using the RTX 3080.

You are ready to have fun with your BIOS
With AMD Smart Access Memory (SAM) you can unlock up to 10% of additional functionality if you are willing to dig around your BIOS. Not everyone will be free to do this, however, and there is nothing wrong with that.

Don’t Buy it if …

You want radiation tracking in 4K
Tracking Ray’s performance on the RX 6800 XT is more than enough at 1440p, but if you want to unlock those brilliant effects in 4K, your money is better spent on Nvidia’s card right now.

You play many DirectX12 games
For current drivers, the AMD Radeon RX 6800 XT lags behind when it comes to DX12 performance, and it just so happens that it will be the API after most of the next few games.

Looking for Nvidia Broadcast or RTX I / O
Currently, Nvidia has a completely new software stack. While AMD has some useful features that can enhance image quality, lack of next-generation I / O API, or AI sound and background detector, Nvidia cards are better for people who use their gaming PC at work.
