TechPowerUp has discovered that AMD's new RX 7900 GRE features some physically altered properties compared to its bigger RX 7900 series brothers. Even though all three GPUs share the exact same die model, the Navi 31 package found on the 7900 GRE is physically smaller than the one found on the 7900 XT and XTX.
According to an image TechPowerUp (via Expreview) made comparing the 7900 GRE's new package size to Navi 21, AD103, and original Navi 31, the RX 7900 GRE's die packaging has been noticeably altered. The package's outer silver border has been thinned down considerably and reshaped so that the package's physical dimensions look like a square. As a result, the GRE's Navi 31 is closer in size to Navi 21 and is smaller than Nvidia's AD103 that powers the RTX 4080. (The physical size of the GPU die and MCDs remains the same; the only thing that became smaller is the GPU packaging.)
