AMD Radeon RX 7800 Benchmark Leaks Out: Faster than NVIDIA’s RTX 4070 [Rumor]

The other day we were talking about the Radeon RX 7800 XT, AMD’s mid-tier RDNA 3 GPU that is yet to hit the retail market. Turns out the chipmaker is prioritizing its cheaper, more affordable non-XT variant. A 3DMark Time Spy benchmark of the Radeon RX 7800 and RX 7700 have surfaced, indicating that AMD will likely release the non-XT variants ahead of the XTs.

The Radeon RX 7800 posts 18,957 in the 3DMark Time Spy graphics benchmark, narrowly beating NVIDIA’s GeForce RTX 4070 (18K points) by roughly 5%. Compared to the Radeon RX 6800, we’re looking at a gen-over-gen uplift of 16%.

The Radeon RX 7800 is most likely using the same chip as the RX 7800M XT, which leaked out last month. 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 is almost certainly based on Navi 32. A cut-down Navi 31 is also possible 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 features 4,096 shaders across 64 Compute Units (CUs) paired with 64MB of L3 cache and a 256-bit memory controller. Additionally, it packs 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.
