Hey, guys!

Welcome to the first test of our new AMD RX6000 card series. We won’t go into the details of the appearance of these two new cards. If you want to know more, please watch our previous unpacking video.

In this video, we’re going to talk about the performance of the RX6800XT and 6800 CARDS. Let’s start with the test platform we prepared for this test.

The CPU is AMD’s latest 9 5900X, coupled with ASUS ROG’s C8G WiFi main board and two Pirate ships’ 4000MHz high frequency bars, aiming to eliminate the CPU bottleneck on graphics card performance.

In terms of power supply, we choose Jinhetian A+ 750W for power supply,80PLUS gold certification, active PFC, full-day capacitor, +12V output power up to 744W, conversion efficiency up to 90%, to meet the power supply requirements of the new 5000 series U and THE new RX6000 series card.

Before we announce the results, the new RX6800XT video card comes with a preset rage mode, which allows the 6800XT to run at higher frequencies and at higher fan speeds. As the name suggests, this is to squeeze all the performance out of a GPU. This feature is currently unique to the 6800XT, not the 6800.

Without further discussion, let’s look directly at the 3DMark theoretical performance test results. To tell the truth, at first run FireStrike Ultra/Extreme both made me a little surprised, because these two scores higher than the 3080 6800 XT to many, even more than we had previously tested 3090 high, but detect TimeSpy this item when I calm down, and 6800XT performance and RTX3080 balanced view of both performance in the DX12 performance should be the same, and in the light after performance test of the Port Royal, the score of 6800XT is 8950, which is still a little short of 3080.

It seems that in the light of this piece, NV has early admission for a few years which does better.

In addition, after turning on the rage mode, the overall performance of 6800XT in all aspects has a small increase. As for the increase in power consumption, let’s press no table here.

Looking at the performance of the 6800, the FireStrike Ultra score is 10,560 and Extreme score is 21,362, which is basically the same as the 3080, while the Time Spy DX12 performance test is about 20% less than the 6800XT performance test, as is the Port Royal performance test.

In terms of games, we tested several representative works: Tomb 11, Tomb 10, Galaxy Breakers and The Territorial Blockade 2; Tomb 11 supports ray tracing, and Galaxy Breaker is one of AMD’s main co-developers of this new RDNA2 card. Let’s start with the regular game frames when you turn off the ray tracing.

It’s not hard to see that RX6800XT is already on par with the 3080, playing in the same game series as tomb Raider, even outperforming the Galaxy Ripper, which is heavily involved in its own development, and not so good in Blockade 2. This is in the past, it is really unthinkable that AMD’s sub-flagship, has been able to face the NV’s sub-flagship. It can be said that AMD’S RDNA 2 new card has made this great progress.

In terms of raytracing, the latest 3DMark version also adds a project called DirectX raytracing function test, which is used to test the performance of dedicated raytracing hardware in graphics CARDS (such as RT Core). AMD RX6800XT and 6800 achieved 27 and 22 frames respectively under this benchmark test. The 3080 got 45 frames. It seems that the NV is doing better. AMD still needs to improve itself.

However, in the actual game experience, the average frame number of 6800 fell to 88.5 immediately after the Galaxy Ripper turned on the light tracking option.

The 6800XT also dropped to 99.9 frames, compared with 178,191 frames. However, such a frame table is still ideal at 4K resolution.

Tomb 11 we went straight to ultra-high ray trace shadow quality, and the result was 6800XT went from 86 to 46,

The 6800 fell from 72 frames to 39 frames, and instantly went back to before liberation. In the end, it was 4K ultra high image quality, and it was estimated that it could go back to 60 frames with high and medium special effects.

Meanwhile, along with new card like the 6800XT, there is Smart Access Memory (SAM) technology, which aims to enable the CPU to Access more video Memory data at once, take full advantage of PCIe4.0 bandwidth, achieve faster data transmission, and eliminate bottlenecks to improve platform performance.

But in actual application, after switching on this function, games in my hand except for the games like The Tomb, there is a visible to the naked eye, killer 2 frames increase (though increased modestly), other games are ascension is not obvious, estimates that remains to be optimized in many ways, this is a blessing AMD the official game of the SAM technology table, a form of latest 3 a platform user might as well open it, but, in general, it is a very good technology.

In terms of power consumption, the single-card power consumption of 6800XT can reach about 257W under AIDA64 full-load copy machine state, and the core temperature can be stabilized at 71℃ (room temperature 27℃) at the highest.

Public version of fan noise is 45DB.

When the rage mode is turned on, the power consumption is further increased to 272W, and the frequency is further increased to 2328MHz.

The fan is noticeably faster and more noisy (57 decibels), but the core temperature is much lower than in automatic mode, at just 67 ° C.

At this time, the total power consumption of the platform reaches about 425W. In short, to drive this card perfectly, you need at least a power source of about 750W.

 

In terms of the 6800, the full load copy machine single card power consumption is 194W, the core temperature highest to 68℃, the fan noise 49DB, the whole machine power consumption in 315W fluctuation, here or suggest you with a 600W above power supply.

Conclusion: Whoever has the better product wins

By the time this article is released, AMD RX6800XT and RX6800 graphics cards had been pre-sold on various e-commerce platforms, and they were all sold out. I found several familiar dealer friends who also said they were out of stock.

There is no doubt that combined with the performance of RX6800XT and RX6800 and the price of 779 and 699 dollars, these two new cards are very nice. The former performance is comparable to RTX3080 (although in light chase aspect still shows a slight decline), but cheaper than 3080 152 dollars , and the current 3080 spot just want 988 dollars upward, it is impossible to buy with the price of the first, the low 3080 basically all depend on the reservation all depend on rob (refers to 835 dollars upward).

It is not hard to imagine that such shortages will continue for some time. Even with AMD’s new cards, the situation will not change much. High-end graphics cards are still hard to find (or pay more for). Basically, I can say with certainty that the AMD and NV will be the biggest winners, both to make money and to get the trusts of consumers.

However, it is not hard to imagine that with the new RDNA 5000 series U in front of AMD, now with a new RDNA 2 card, and a lot of exclusive technology bonus (such as Smart Access Memory), in the future the 3A platform will be more and more, it is expected that more people will say: “AMD, Yes!”.
