During the HEDT CPU shortage, I noticed a drop in price for the w3175x, though they remain costly. While searching for retail chips, I stumbled upon unusual ES variants that reminded me of a video where Linus tested non-existent SKU ES CPUs. Have you heard of ES processors with fewer or more cores than the final model? If genuine, they might be early prototypes, making it unclear what their maximum performance could be. The listing suggests these chips have been overclocked to around 4 GHz, which is a reasonable clock speed given available cooling. The only oddity is the core temperature image—possibly someone opened it, but it seems impossible to cool such a CPU effectively during Cinebench at 40°C. Overall, the price appears reasonable compared to similar items.

Even though they might be genuine, remember that bios support is probably not available, so these chances are likely to fail.

This was the primary issue I considered. I’d consider giving up the $400 risk, since those motherboards are quite costly. I could contact the seller to confirm what board they say is being used, and if it works out, maybe I could sell my 7980xe for more than the CPU expenses and still end up with a free upgrade. The other point is that my 8x16GB RAM wouldn’t reach full memory performance (since the Xeon has 6 channels), but based on what I know it shouldn’t be a major drop—just not the best match for the CPU.
