General details from Microsoft
Most eBay listings are wrong about the 7V73X specs because they are reusing the 7773X specs. Main differences:
- Base clock is 1.85GHz, the bosts remain the same at max single core boost at 3.5GHz and max all core boost at 3GHz. The turbo multipliers for different loads are probably also different.
- PPT/TDP is fixed at 225W and not 280W as many listings claim. Configuring the TDP and PPT has no effect.
- CPU is PPT limited when SMT is enabled causing frequency to be capped to ~2.7-2.8GHz.
- SMT is supported.
