Since last year, AMD has been teasing the Radeon RX 7900 XTX and XT, and now we have a leak from RedGamingTech that purports to give the entire specifications of AMD’s next mid-high-end lineup. RGT is disclosing the specifications of the RTX 4070 Ti equivalent RX 7800 XTX and the RX 7800 XT and 7700 XT.
The RX 7800 XTX, according to the leak, will be built on the same Navi 31 processor and will have 16GB GDDR6 vRAM coupled to a 256-bit bus. It will have 300 watts of total board power and performance aims that “roughly compete with the 4070 Ti.” However, RGT also claims that this particular SKU may be canceled, so the situation remains somewhat ambiguous.
The RX 7800 XT, on the other hand, is claimed to be slightly slower than the NVIDIA RTX 4070 Ti. This card has 60 CUs, a 2.6 GHz game clock, and a 2.8 GHz boost clock. This translates to a maximum FP32 TFLOPs performance of 43 and a sustained TFLOPs performance of 40. The card will have 16GB of VRAM on a 256-bit interface and will consume only 285W (total board power).
The peak TFLOPs performance of the RX 7700 XT will be 32 TFLOPs, with a sustained TFLOPs performance of 29.4 TFLOPs. The card’s TBP will be only 225W. The cache sizes for the RX 7800 XT and 7700 XT will be 64MB and 48MB, respectively. RGT notes that the smaller 54 CU variant has been canceled.
The 6650/6700 XT GPUs will be replaced by the RX 7600 XT, while the 6600 XT and 6650XT cards will replace the RX 7600. In terms of performance goals, these are very conventional substitutes.
|Model||Architecture||CUs||Game Clock||Boost Clock||Peak TFLOPs||Sustained TFLOPs||Memory||Memory Interface||TBP|
|RX 7800 XTX||Navi 31||N/A||N/A||N/A||43||40||16GB GDDR6||256-bit||300W|
|RX 7800 XT||Navi 31||60||2.6 GHz||2.8 GHz||43||40||16GB GDDR6||256-bit||285W|
|RX 7700 XT||Navi 32||40||2.0 GHz||2.6 GHz||32||29.4||16GB GDDR6||256-bit||225W|
It’s worth noting that Navi 33 will be AMD’s high-volume section, with the company aiming for mass manufacture. However, the mileage may vary depending on the quality of the silicon you obtain. Historically, AMD has struggled to keep its boost clocks stable, but NVIDIA has never had this issue. AMD will hopefully be able to improve on this with Navi 32 and 33.
