AMD today released the Radeon RX 6950 XT, RX 6750 XT and RX 6650 XT graphics cards. They are updated Radeon RX 6900 XT, RX 6700 XT and RX 6600 XT but with slightly faster GPUs, faster memory and higher TDP. In the current reality, we have to rely on the experience of our Western colleagues who have already familiarized themselves with these cards. In this article we will review the flagship Radeon RX 6950 XT based on resource ratings Tom’s hardware, Guru3D and TechPowerUp.
The Radeon RX 6950 XT model is based on the same 7nm Navi 21 GPU as the regular Radeon RX 6900 XT, only it’s labeled KXTX instead of XTX. It consists of 80 processing units with 5120 stream processors, 320 texture units, 128 rasterization units and 80 ray tracing acceleration units. The gaming reference frequency of the GPU is 2100 MHz (85 MHz higher than the RX 6900 XT) and increases to 2310 MHz (60 MHz higher than the predecessor) in boost mode. The novelty is equipped with 16 GB of GDDR6 RAM with a 256-bit bus. The data transfer rate is 18 Gbps per contact. Because of this, its bandwidth isn’t 512GB/s like the regular Radeon RX 6900 XT, but 576GB/s. There’s also a 128MB infinity cache buffer. The graphics card’s rated power consumption (TGP) at reference frequencies is 335 W, which is 35 W higher than the Radeon RX 6900 XT.
The novelty came out both in the reference version of AMD, and in the form of proprietary solutions from the company’s partners. Tom’s Hardware journalists studied the Sapphire Radeon RX 6950 XT Nitro + Pure model (on the first photo), Guru3D received the MSI Radeon RX 6950 XT Gaming X model trio (second photo). The TechPowerUp portal could get a graphics card in several versions at once. For coverage, let’s take the Gigabyte Radeon RX 6950 XT Gaming OC specs (in the third photo). All of them are equipped with massive and efficient cooling systems and have an optional factory overclocking of the GPU. Although the latter adds several frames per second in games, depending on the version of the graphics card, it does not affect the overall picture. The Radeon RX 6950 XT proved to be very fast even with reference specifications in games. But only without ray tracing, in which it is even inferior to the two classes lower model – GeForce RTX 3080 10GB. But more on that below.
According to TechPowerUp colleagues who tested the Radeon RX 6950 XT in 25 games, the new product was an average of 9% faster than its predecessor. The resource Tom’s Hardware, which tested the accelerator in 8 games, had a difference of 10% in favor of the new card. Guru3D reports similar results for 9 games.
Speaking directly about competitors, the Radeon RX 6950 XT is on average 1-2% faster than the GeForce RTX 3090, but about 7% slower than the GeForce RTX 3090 Ti. Of course, in this case we are talking about the performance of the accelerator in games with 4K resolution and maximum graphics settings.
The card was also tested at 1440p. In this case, Tom’s Hardware notes that the Radeon accelerator was on average 3% faster than the GeForce RTX 3090 Ti and 9% faster than the regular Radeon RX 6900 XT.
The data from their peers at TechPowerUp and Guru3D are similar. The Radeon RX 6950 XT only outperformed its competitors on a few gaming titles.
Also in gaming tests with a resolution of 1080p, the new “red” overtook everyone. The average frame rate was 184.8, while the Radeon RX 6900 XT model had 173.2 and the GeForce RTX 3090 Ti 177.9 (according to TechPowerUp).
In turn, the Tom’s Hardware resource states that at this resolution, the Radeon RX 6950 XT is on average 5% faster than the GeForce RTX 3090 Ti and 6% faster than the Radeon RX 6900 XT.
But with ray tracing, the novelty, as with all representatives of the Radeon RX 6000 series, things are not exactly the best. In some games you can of course also enjoy the rays at a fairly high frame rate (over 100). But in general the situation is not the most impressive. Especially at 4K resolution. On average, the Radeon RX 6950 XT’s beam performance is 50-56% less than the GeForce RTX 3090 Ti. The closest competitor here for Radeon RX6950XT is GeForce RTX 3080 10GB. However, the latter also overtakes the Radeon model.
In terms of power consumption, temperature and noise level. The Gigabyte Radeon RX 6950 XT Gaming OC was the coldest, but at the same time the second quietest in the tests. Portal TechPowerUp notes that he has not seen temperatures above 70 degrees Celsius. At the same time, the maximum noise level of the graphics card was 36 dBA. The maximum power consumption in games is 398 watts. And the peak (duration 20 ms) was 533 watts.
The version of the MSI Radeon RX 6950 XT Gaming X Trio tested by the Guru3D resource heated up to 75 degrees Celsius. At the same time, the noise level was 35 dBA. The maximum measured power consumption in games was 430 watts. Peak – 460 watts.
The Sapphire Radeon RX 6950 XT Nitro+ Pure model at Tom’s Hardware warmed up to 72.5 degrees. Its maximum noise level was 39.8 dBA and its power consumption was 401 watts. The source did not give the peak consumption.
