The specifications of AMD’s budget RDNA 2 graphics cards, namely the RX 6700 and the 6700 XT have been leaked out by Patrick Schur over at Twitter. These parts will succeed the existing Navi 10 based RX 5700 and the 5700 XT, respectively.
We already had an idea about the bus width and shader count of these cards, but now we know the memory size and TGP as well. The shader counts of these parts are expected to stay the same as their RDNA 1 counterparts, 2560 cores (40 CUs) for the 6700 XT and 2,304 cores (36 CUs) for the 6700. The memory bus is getting reducing for both the cards, from 256-bit to 192-bit. This deficit will be compensated by the Infinity Cache. Considering the pricey nature of SRAM, these GPUs will likely feature half as much Infinity Cache compared to the Big Navi parts: ~around 64MB.

The VRAM buffers are getting a massive upgrade, from 8GB to 12GB on the RDNA 2 parts. This falls in line with AMD’s strategy of offering nearly twice as much memory as competing NVIDIA offerings. As far as the TGP goes, the RX 6700 XT is expected to draw close to 200W while the 6700 will be limited to under 160W.

Comparing the Radeon RX 6700 XT against the GeForce RTX 3060 Ti, you can see that the shader strength is roughly the same (4,864/2= 2,432 cores), but the latter has a wider bus paired with a smaller VRAM buffer. This means that the RTX 3060 Ti will likely have an advantage at 1440p and 4K while the RX 6700 XT will be optimal for 1080p gaming. In terms of the pricing, both the cards should be priced around $400, but we reckon the 6700 XT will be a bit more expensive on account of the Infinity Cache.
