Constructed on the AMD Navi 31 XL silicon, the RX 7900 GRE utilizes a chiplet-based GPU architecture that allows for a compact size comparable to the Navi 32, fitting AMD's design approach for the mobile RX 7900 series. The RX 7900 GRE features 80 RDNA3 compute units, amounting to 5,120 stream processors, and includes 160 AI accelerators, 80 Ray accelerators, and 320 Texture Mapping Units (TMUs), with a full set of 192 Raster Operation Pipelines (ROPs). Equipped with 64 MB of Infinity Cache and using a 256-bit memory interface, the card supports 16 GB of 18 Gbps GDDR6 memory, achieving a memory bandwidth of 576 GB/s. The Total Board Power (TBP) is 260 W, consistent with the RX 7800 XT, and the GIGABYTE Gaming OC variant is expected to have a slight factory overclock to boost performance.
