WE NOW HAVE a new best ever Radeon graphics card, the RX 6950 XT. This three-fan monster has, AMD says, “been engineered to deliver the ultimate 4K gaming experience”. Basically a refreshed 6900 XT, it is built around the same 7nm Navi21 GPU with 5,120 Stream Processors and 80 Compute Units. It is clocked faster though, with the game clock jumping from 2,015MHz to 2,100MHz, a four percent bump.
The maximum boost speed gains 60Hz to 2,310MHz and although memory is the same, 16GB of GDDR6, it’s now 18Gbps rather than 16Gbps, while memory bandwidth rises from 512GB/s to 576GB/s. AMD quotes the ‘effective’ memory bandwidth using the Infinity cache, now 1,793.5GB/s, up from 1,664.2GB/s. That’s some useful extra bandwidth. All of these changes have pushed the power consumption to…
