This week, AMD officially announces its updated family of RDNA2 GPUs. Radeon 6950 XT, Radeon 6750 XT and Radeon 6650 XT are substitutes and / or additions to Radeon 6900 XT, 6700 XT and 6600 XT. The minimum prices for each card are $ 1099, $ 549 and $ 399 each. Radeon 6800 XT is not updated, but it does not change and will remain on the market, as well as Radeon 6700 XT. Radeon 6600 XT will be retired.
The 6950 XT is $ 100 more expensive than the Radeon 6900 XT, while the Radeon 6750 XT is 1.15 times more expensive (than $ 479). The Radeon 6650 XT is only $ 20 more. Clock and memory bandwidth have been slightly improved, although the TBP (total board power) has increased, respectively, to 35W to 335W for the Radeon RX 6950 XT and 20W to 250W and 180W for the 6750 XT and 6650 XT.
The clock speeds of the GPU are almost identical between the 6 × 00 and 6 × 50 models. The Radeon RX 6950 XT has a base clock speed of 2.1 GHz and an accelerated frequency of 2.31 GHz, which is an increase of 4.2% and 2.6%, respectively. The 6750 XT is 2.9% and 0.07% faster than the 6700 XT (don’t be surprised), and the 6650 XT is 2.2% and 1.7% faster than its predecessor. VRAM’s capabilities are identical between the refreshed RDNA2 and the original taste. While AMD partners have some leeway to sell their own custom overclocked cards, AMD vendors don’t usually push their GPUs too hard. AMD tends to aggressively clock its reference cards and doesn’t leave much room for the clock.
VRAM speeds, by contrast, have increased slightly. All three cards now have 18Gbps VRAM instead of 16Gbps VRAM, a gain of 1.125x. However, it is not clear how RDNA2 GPUs with limited memory bandwidth are. Our tests showed only limited evidence of memory bottlenecks in the resolutions that people are likely to target with these cards. A 12.5% VRAM clock can be expected to provide between 1.05x – 1.1x extra performance depending on how limited the bandwidth of the title is. The distribution of Infinity Cache is unchanged on these chips. The 6950 XT has 128MB L3, the 6750 XT uses 96MB L3, and the 6650 XT has 32MB L3.
The 6600 XT was not our favorite GPU when it debuted, and the 6650 XT does nothing to solve its problems. The 6750 XT and 6950 XT are better positioned from the start. As for the best balance between affordability and performance for AMD at the moment, it will probably be either the 6700 XT or the 6750 XT. Although I have expressed dissatisfaction with AMD’s prices in the past, more than a year of incredibly high prices suggests that anyone who can find one of these cards at or near MSRP should take it. The good news is that with each passing day, this is becoming less and less true. Overall, markets appear to be normalizing.
AMD also gave brief details about the new launch, called Raise the Game. Titles such as Saints Row and Sniper Elite 5 (yet to be announced) will be bundled with qualifying cards from various OEMs. According to AMD, anyone who purchases a GPU from a participating retailer will receive a code that can be redeemed once full details of the promotion are available later this quarter.
If you’ve been watching an RDNA2-based GPU for a while, these new refreshes may be worth checking out. While not dramatically faster than the first models that AMD debuted, they offer the same benefits with a little more watch on top. If you are not selling RDNA2 as a solution for you at the moment, these cards are unlikely to change your mind. We’ll see a more exciting match later this year when Nvidia’s RDNA3 and Lovelace face off.
