AMD Radeon RX 7800 and 7700 Expected to be Announced at Gamescom in Late August [Rumor]

AMD’s Radeon RX 7800 and 7700 are slated to hit the retail market in September. The budget Navi 32 GPUs should be announced at Gamescom next month. Set to be held in Cologne from August 27 to 2023 2023, it will be the perfect time for AMD to release its next RDNA 3 graphics cards. Both GPUs will leverage the Navi 32 die and go up against the GeForce RTX 4060 Ti and RTX 4070.

A 3DMark Time Spy benchmark of the Radeon RX 7800 and RX 7700 surfaced a while back, indicating that AMD will likely release the non-XT variants ahead of the XTs. The Radeon RX 7800 registers 18,957 points in the 3DMark Time Spy graphics benchmark, narrowly beating NVIDIA’s GeForce RTX 4070 (18K points). Compared to the Radeon RX 6800, we’re looking at a gen-over-gen uplift of 16%.

The Radeon RX 7800 likely utilizes the same chip as the RX 7800M XT. The mobility GPU scored 17,842 in the Time Spy graphics benchmark, which falls within the ballpark of the supposed RX 7800.

The Radeon RX 7800 will most likely leverage the Navi 32 GPU. A cut-down Navi 31 is also a possibility but won’t be economically feasible. AMD would need ample defective Navi 31 dies and/or leftovers from the RX 7900 XT production line for this to work. Anything else would result in poor margins and possible losses.

The fully enabled Navi 32 die consists of 4,096 shaders across 64 Compute Units (CUs) paired with 64MB of L3 cache and a 256-bit memory controller. In addition, you’re looking at 256 Texture Units and 128 Raster Output Units alongside 64 RT Cores (one per CU). The GPU has a TBP of 300W and a boost clock of almost 3GHz.
