AMD announced their Radeon RX 7900 XTX and XT last year and today we have a leak from RedGamingTech that appears to have the full specification of AMD's upcoming mig-high end lineup. We already covered the RX 7800 XT and 7700 XT in a previous story but RGT is also leaking the specifications of the 4070 Ti-equivalent RX 7800 XTX.
The RX 7800 XTX is going to be based on the same Navi 31 chip and will have a 16GB GDDR6 vRAM connected to a 256-bit bus. It will have a total board power of 300 watts and performance targets "will roughly compete with the 4070 Ti". In a somewhat contradictory statement however, RGT also claims at the same time that this particular SKU might end up getting cancelled - so we are not entirely sure whats happening here.
According to RGT, the RX 7800 XT will be slightly slower than the NVIDIA RTX 4070 Ti. This particular card has 60 CUs and a game clock of 2.6 GHz and a boost clock of 2.8 GHz. This means you are looking at a peak FP32 TFLOPs performance of 43 TFLOPs and a sustained TFLOPs performance of 40 TFLOPs. The card will consume only 285W (this is the total board power by the way) and have 16 GB of VRAM across a 256 bit bus.
The RX 7700 XT on the other hand will have a peak TFLOPs performance of 32 TFLOPs and a sustained TFLOPs performance of 29.4 TFLOPs. The card will have a TBP of just 225W. The RX 7800 XT and 7700 XT will have a cache size of 64 MB and 48 MB respectively. RGT also notes that the smaller 54 CU variant has been cancelled.
The RX 7600 XT is going to have the performance target of replacing the 6650/6700 XT GPUs while as the RX 7600 will be replacing the 6600 XT and 6650XT cards. Pretty standard, really. Not surprisingly, Navi 33 is going to bee the high volume segment of AMD and they are going to go for mass production in this segment. Depending on the exact quality of silicon you get - mileage could vary. AMD has historically struggled a bit to maintain its boost clocks (NVIDIA typically does not have this problem) so hopefully they will be able to improve upon this with Navi 32 and 33.
