AMD Radeon RX 7900 GRE Configured with 80 CU?
AMD's upcoming China-exclusive Radeon RX 7900 GRE (Golden Rabbit Edition) graphics card is reportedly configured with 80 compute units (CU), and not the previously thought 84, according to a leaked TechPowerUp GPU-Z screenshot. While GPU-Z 2.54.0 isn't fully aware of the RX 7900 GRE, and can get some hard-coded details (such as release dates) wrong, since it has the ability to detect "Navi 31" and the RX 7900 series, it is able to count the compute units.
The screenshot describes the RX 7900 GRE as featuring 80 CU, or 5,120 stream processors—the same count as the previous-gen RX 6900 XT, but based on the newer RDNA3 graphics architecture. Also detected are a TMU count of 320, ROP count of 80 (a vast reduction from the 192 available on the silicon, if true). We've known from older reports that the RX 7900 GRE is configured with a 256-bit wide GDDR6 memory interface, holding 16 GB of video memory. What's new is that while the RX 7900 XT and RX 7900 XTX use 20 Gbps memory, the RX 7900 GRE is given slower 18 Gbps memory, as detected by GPU-Z. This results in a memory bandwidth of 576 GB/s, a significant reduction from the 960 GB/s enjoyed by the RX 7900 XTX.

Did you create it.

btw, this could be the solution the how RDNA3 allows compute units are used active or inactive to make each SKU.
this is of course speculative
