AMD Radeon RX 7800 and 7700 expected to be announced at Gamescom in late August [Rumor]

AMD's Radeon RX 7800 and 7700 are expected to go on sale in September. The Navi 32 GPUs are expected to be announced at Gamescom next month. Gamescom, which will be held in Cologne from 27 to 2023, 2023, will be the perfect time for AMD to showcase its upcoming RDNA 3 graphics cards. Both GPUs will leverage the Navi 32 matrix and take on the GeForce RTX 4060 Ti and RTX 4070.

A 3DMark Time Spy benchmark of the Radeon RX 7800 and RX 7700 surfaced a while ago, indicating that AMD will likely release the non-XT variants before the XTs. The Radeon RX 7800 scores 18,957 points in the 3DMark Time Spy graphics benchmark, narrowly beating NVIDIA's GeForce RTX 4070 (18,000 points). Compared to the Radeon RX 6800, we see a 16% increase generation over generation.

The Radeon RX 7800 likely uses the same chip as the RX 7800M XT. The Mobility GPU scored 17,842 in the Time Spy graphics benchmark, which matches the rumored RX 7800.

The Radeon RX 7800 will most likely use the Navi 32 GPU. A scaled-down Navi 31 is also a possibility, but will not be economically feasible. AMD would need a large number of faulty Navi 31 dies and/or leftovers from the RX 7900 XT production line for this to work. Any other solution would result in low margins and possible losses.

The fully enabled Navi 32 chip features 4,096 shaders across 64 compute units (CUs), 64 MB of L3 cache, and a 256-bit memory controller. Additionally, there are 256 texture units and 128 frame output units with 64 RT Cores (one per CU). The GPU has a TBP of 300W and a boost clock of almost 3GHz.
