During AMD’s presentation at China Joy in Shanghai, China, the much-anticipated Radeon RX 7900 GRE “Golden Rabbit Edition” was officially announced. This new graphics card is equipped with the Navi 31 GPU, which has slightly fewer cores compared to the 7900 XT models. It will be shipped with 16 GB of memory.

Unlike the rumored 5376 Stream Processors, this model offers 5120 cores, with only 80 Compute Units enabled on the GPU. As a result, the card comes with reduced specifications compared to the RX 7900 XT, affecting memory (20 GB vs. 16 GB) and memory bus (320 vs. 256-bit). The Infinity Cache has also been reduced from 80MB to 64MB. Additionally, the TBP (Total Board Power) has been lowered to just 260W.

It’s worth noting that the memory has been down-clocked to 18 Gbps, resulting in a bandwidth of 576 GB/s instead of the expected 640 GB/s. Moreover, the card features lower clock speeds, with a base, game, and boost clock of 1270/1880/2245 MHz, compared to the XT’s 1385/2025/2395 MHz.

The GPU is identified as Navi 31 XL, but its package is noticeably smaller, confirming the presence of a hybrid Navi 31/32 design. This design suggests that a smaller package will be utilized for the upcoming Navi 32 graphics processor, indicating that 2 out of 6 Infinity Cache dies are disabled or dummy.

Chinese media has already tested the graphics card, and while it is slower than the RX 7900 XT, it outperforms NVIDIA’s RTX 4070. Its performance is expected to be similar to the Radeon RX 6950XT, though. Notably, AMD advertises it as the successor to the RX 6800 XT.

In terms of availability, the Radeon RX 7900 GRE will only be released by three board partners: Sapphire, PowerColor, and XFX. AMD itself will produce a reference model, as indicated by official materials and its availability for media reviews. Official slides show US pricing of $649 and AMD China did confirm that RX 7900 GRE will launch globally through system integrators.
