Update: See our buy location page for information on the latest AMD GPU:

. So the main discoveries of AMD 6000 series graphics cards have come and gone. The general reaction from the technical community is: We are impressed and still a bit skeptical before we get there, but quietly full of hope. We think the response from the folks at Nvidia is a little less positive. "Rage Mode" and "Smart Access Memory" are two special features that everyone talks about. Quickly read our overview of these two features here.

Now that we have some data, we can compare the two heavyweights in the 6000 series: 6800 XT and 6900 XT, also known as "Big Navi". In terms of specifications, there is not much difference between the two cards, but we will check the improvements AMD has made since the previous generation.

The main focus here will be the difference in FPS performance. There has been discussion about whether the FPS displayed by AMD represents the average FPS or the maximum FPS, because this does not seem to be clearly stated in the presentation. For consumers and AMD, we expect these figures to actually be average FPS; otherwise, once third-party benchmarks are released, they may be strongly opposed. For this reason, we believe that these concerns are unfounded, but, as always, we have reservations about the official FPS data. Our recommendation is to always wait for an independent benchmark test before deciding which card is right for you. We will keep you informed of the latest leaks in a timely manner.

Now, it goes without saying, let's go straight.

As the above leak implies, the 6800 XT and 6900 XT specification list is very similar, except that the main difference between the two cards in the key area of "computing unit" is.

As the leak above implies, the 6800 XT and 6900 XT specification list is very similar, and the main difference between the two cards is only in the critical "compute unit" area.

For those running higher resolution displays, especially 4K, the memory bottleneck proved to be an increasingly serious performance issue. Regardless of the main frequency of the graphics card, if the video memory bandwidth is not enough, the minimum FPS will often be low in comparison, even if the average FPS is high, causing the game to freeze. The fluctuation is obvious. Both the 6800 XT and 6900 XT are equipped with an impressive 16GB GDDR6 VRAM, 16Gbps memory speed and a 256-bit memory bus.

Although this means that the VRAM of these two AMD cards is higher than Nvidia's 10GB GDDR6 3080 RTX, but compared to 19Gbps memory speed and 320-bit memory bus, they are lower. In addition, they are inferior to the Green Team’s flagship model 3090 RTX in these three aspects, because it is equipped with 24GB of VRAM, 19.5Gbps memory speed and 384-bit memory bus.

Overall, this shows that this means that the 3090 RTX can still be a winner in 4K performance compared to the more powerful AMD card, but AMD claims it has the ability. Based on the technology developed for its Ryzen CPU, AMD's "unlimited cache" clearly allows the CPU to run at 2.17 times the bandwidth, which is 2.17 times greater than what you would normally expect from a memory bus. 256-bit. This means that you can use a smaller bus that is "significantly" better than Nvidia cards in this regard, saving power consumption and heat generation. In any case, the two higher-end AMD cards have the same memory specs.

For those using higher resolution displays, especially 4K, the memory bottleneck has proven to be an increasingly serious performance issue. Regardless of the graphics card clock speed, if the memory bandwidth is not enough, this often results in a low minimum FPS during benchmarks, even if the average FPS is high, leading to possible game freezes due to significant frame rate fluctuations. Both the 6800 XT and 6900 XT are equipped with an impressive 16GB GDDR6 VRAM, a 16Gbps memory speed, and a 256-bit memory bus.

Although this means that these two AMD cards have higher VRAM than Nvidia's 3080 RTX with less than 10GB of GDDR6, but compared to the 19Gbps memory speed and 320-bit memory bus, their memory video is less. Also, in all three respects, it is lower than the green team's flagship 3090 RTX because it is equipped with 24GB of VRAM, 19.5Gbps of memory speed, and 384-bit memory bus.

In any case, the two higher-end AMD cards have the same memory specs.

is similar to its Ryzen processor, AMD managed to get great efficiency out of its next-gen graphics card. Part of the reason is that using the aforementioned infinite cache allows for a smaller memory bus. Additionally, improvements in computer unit manufacturing and other developments have increased performance per watt by 54% over the previous generation.

Now claims to have improved performance between 6800 XT and 6900

The heat. In fact, the smaller of the two cards, the recommended power supply for the 6800 XT is 750W, while the 6900 XT requires 850W. However, through some unknown mysterious scientific methods, the two cards have the same "TDP" (Thermal Design Capability). Although TDP is a problematic metric and cannot really be used when comparing AMD and Nvidia, it is usually an accurate representation between cards in the same series, so the same number between the two cards is interesting. In any case, it is recommended to wait until independent testers use these two components to see if this is indeed the case, or if the 6900 XT requires an improved cooling solution compared to the 6800 XT.

In addition, its computing unit manufacturing and other development improvements have increased the performance per watt by 54% over the previous generation.

Now, with the performance improvement between 6800 XT and 6900 XT (more on that later), I expect power consumption to increase at the same time, and considering that the two GPUs use the same cooling solution, increased heat generation. In fact, the smaller of the two cards, the 6800 XT is equipped with the recommended 750 W power supply, while the 6900 XT requires 850 W.

Although there is news that the Big Navi card will be equipped with a higher 2,040MHz game clock and a 2,330MHz boost clock, the 6900XT and 6800XT actually both have a 2,015 MHz game clock and a 2,250 MHz boost clock. AMD does not provide us with the traditional "basic" clock speed measurement. Similar to increasing speed is a fairly technical measure, it rarely represents the frequency at which the GPU completes most processes, and the "base" clock is a very low rate, even an idle computer rarely does this. It will reach. The "game" clock is AMD's way of trying to give an indication of how fast the GPU is expected to reach during a typical game; obviously how this will translate into reality is still somewhat undecided for most people before a third party can prove. that.

Similarly, before we look at more test data, how long any card can keep the boost clock is unknown. Some previous generation AMD graphics cards rarely achieve the speed boost and cannot be sustained for a period of time to impact performance. It is hoped that the speed of these two new cards is not just marketing techniques. The number of

Compute Units is the difference between the specifications of the two cards, from the 72 cores of the 6800 RX to the 80 cores of the 6900 RX, there is a significant increase (more than 11%). This is the source of the extra power of the most expensive cards.

As far as we know, both cards have the same software. The Rage mode and smart memory access mentioned above will be functions that the owners of these two cards can use. They also have the latest Ryzen 5000 series processors and AM4 motherboards. Both GPUs will use the new "Radeon Boost" and "Radeon AntiLag" technologies to increase response time and reduce latency. These two graphics cards will also be fully compliant with the "DirectX 12 Ultimate" standard-which means compatibility means they will support mesh shading, variable speed shading and sampler feedback. Although DLSS (Deep Learning Super Sampling) will still be Nvidia’s exclusive technology, AMD has revealed that they have developed their own ray tracing technology. More details will appear in the near future. You can expect both cards to take advantage of this A little feature. Although it remains to be seen how it compares to Nvidia's own implementation.

In the final analysis, regardless of the technical similarities between the two cards, people care about performance. At this stage, we only have AMD's own benchmark tests based on FPS. It is expected that there will be more technical benchmarks from third parties next month.

is unusual in that AMD did not display 1080p performance on any graphics card released on October 28, using 1440p as the minimum resolution. Whether you're trying to hide the poor performance compared to Nvidia products at this resolution, or just acknowledging that the next-gen GPU will bring the normal baseline gaming display to 1440p next year, there's only time ( and third-party independent benchmarks).

According to AMD, below we can see the 1440p performance of the RX 6800 XT calculated at FPS in many games. The Nvidia RTX 3080, which is priced at over $ 50, was used as a comparison. According to the final notes, both cards were tested with Ryzen 5900 X and AM4 motherboards.

Although we wanted to compare this performance with the performance of the 6900 XT playing the same game at 1440p, we only saw the FPS performance of the RX 6900 XT at 4K resolution; we will have to wait for the arrival of the first independent benchmark

The intended use of the two GPU-6900 XTs, like its competitor Nvidia RTX 3090, was designed with 4K in mind; if you are a gamer who plays 1440p or 1080p of course use just one screen, then 6800 plus $ 350 XT seems like an unnecessary luxury. If you're considering operating two or more displays at 1440p, the 6900 XT may come in handy, but there are other factors at play here: sampling and supersampling efficiency determine performance across multiple displays. Rather than just the original specs, this may vary from game to game, application to application.

We can safely assume that the 6900 XT will outperform the 6800 XT at 1440p and 1080p because it has more compute units, but the question of how much is $ 350. If the earlier versions of AMD and Nvidia have any guiding significance, then the improvement between Big Navi and its younger brother will become less noticeable as their resolution ratio decreases, so their performance difference at 1440p may be less than your teenager in 4k, or even less at 1080p than 1440p.

Only time (and third-party independent benchmarks) will tell.

In the end, while this reinforces the difference in the intended use of the two GPUs, the 6900 XT, like its competitor Nvidia RTX 3090, was designed with 4K in mind, if you are a gamer playing 1440p or 1080p of course. .

Although 4K performance is not a feature of real interest to the vast majority of gamers in today's market, it is becoming a new standard for manufacturers to show the best performance of their hardware at its limits. This is an area where AMD is expected to compete with Nvidia in this regard. Nvidia's Ampere architecture and its large number of shaders do perform well on 4K resolution displays, although if AMD's results can be trusted, they seem to end up being less. , In the best case, outperforms its competitors.

The following is the performance data of the two graphics cards announced by AMD. According to the endnotes, both cards were tested using Ryzen 5900X CPU and AM4 motherboard. Unfortunately, AMD did not show the 6900 XT without Rage mode or smart memory access (disguise), which begs the question whether this indicates that its performance will be disappointing. For whatever reason, we cannot compare the performance of the two cards with these features disabled based on current information.

With some digital magic (basic math), we can get the six games FPS comparison chart with comparable data based on a certain percentage.

Unsurprisingly, the RX 6900 XT performs better of the two, although whether these FPS gains are enough to justify the cost increase is entirely up to the buyer.

You will notice that in the image above, there is no specific description of the RX 6800 XT's FPS with anger mode and smart memory access enabled. However, with some digital magic (basic math), we can get FPS comparison charts for six games with comparable data based on a certain percentage.

Unsurprisingly, the RX 6900 XT performs better of the two, although whether these FPS gains are enough to justify the cost increase is entirely up to the buyer.

"Big Navi", like its rival Nvidia, is the best card for enthusiasts. For those who are not a problem when buying a PC, if (still a big yes at this stage) this performance data is credible, then they must have successfully challenged the 3090 RTX at a low price of $ 500. Rage mode Smart memory access especially, means that to fully realize this gain, you have to pair the card with one of the latest Ryzen CPUs, but the current price of the Ryzen 5900X is $ 549, which is a total difference of $ US. 49 as claimed by AMD Superior performance (compared to Nvidia GPU and Intel CPU). When

compares the 6900 RX to the 6800 RX, it becomes a more personal choice. If your needs are purely for 1080p or 1440p gaming, it seems difficult to justify spending $ 350 compared to the 4K numbers we can get today, because it can show that FPS performance is less improved. Better to spend this money elsewhere for the full build, maybe for a new SSD or for a new display.

For 4K gamers, the question is: "Is the extra FPS gain at this resolution worth my money?" For those considering operating multiple 1440p displays, it may even be two 4K displays for workstations and games, then we highly recommend that you wait for independent testing online as this data is not currently available.

As always, the longer the time, the clearer the image. We always recommend waiting for an independent benchmark. However, if you have to buy now, or you may be worried about inventory issues and want to buy these cards before they run out - for those with deep pockets who must have the best of tech, the AMD Radeon 6900 RX looks like one of the best. notch card For others who want to buy an enthusiast card, we recommend AMD Radeon 6800 RX.
