AMD’s Radeon RX 6×50 XT refresh is set to land later this month with increased boost clocks and faster memory. This additional performance will, of course, come at the cost of slightly higher power consumption. The top-end RX 6950 XT will retain the Navi 21 die in all its glory with 80 CUs or 5,120 shaders. The boost clock will be bumped up from 2,250 MHz to 2,310 MHz for an increase of 4% over the vanilla variant. The memory will also be replaced with faster 18Gbps modules for some additional frames at higher resolutions. The GPU will have a TGP of 335W, a 35W increase over the RX 6900 XT. The price will also likely go up by a notch, probably to $1,049 or $1,099.
Below the 6950 XT, we have the Radeon RX 6750 XT leveraging the Navi 22 die with 40 CUs and 2,560 stream processors. The boost clock will be raised by 3%, from 2,581 MHz to 2,600 MHz. The memory will get the same treatment with faster 18Gbps modules across a 192-bit bus along with 96MB of L3 cache. The bandwidth totals 432 GB/s, a healthy jump of 48 GB/s over the 6700 XT. The power draw will be upper to 250W, a marginal increase of 20W over the 6700 XT’s 230W.
Finally, there’s the RX 6650 XT which features the Navi 23 core with 32 compute units or 2,048 shaders. The GPU will be paired with 17.5Gbps memory chips across a 128-bit bus for an external bandwidth of 280GB/s, a neat bump over the 6600 XT’s 256GB/s. The Infinity Cache and memory buffer size are unchanged at 32MB and 8GB, respectively. The TGP has been raised by 20W to 180W (vs 160W for the RX 6600 XT). In tandem, the boost clocks have also gone up by 2%, from 2,589MHz on the 6600 XT to 2,636 MHz on the 6650 XT.
The prices for all three SKUs should be a smidge higher than their predecessors. The availability should be markedly better, allowing for consistent market pricing. The official launch is slated for next week, and that’s where we’ll know more about the exact performance gains and prices. If I had to guess, I’d say the RX 6x50s will be 5% faster than their contemporaries on average, with 1440p and 4K seeing larger gains due to the improved external bandwidth.
