The most powerful among all Xeons in the Sandy Bridge family is the 2690. I tested the 1650 at 4.5 GHz, and in Cyberpunk 2077 with a GTX 1080, the FPS drops were terrible. I also tested the 2680 v2 without overclocking, and despite having two more cores, it seems to be weaker than the 2690. In my opinion, the processor is great. I overclocked the Turbo mode to 3.4 GHz on each core, and in CPU-Z, it reaches 3450 points. In CP2077 with a GTX 1080 at 2k resolution on medium settings, it hardly drops below 60 FPS. Bought it for 13 euros on eBay. Fantastic. [Sep '23 Kac3Vielky]

The Intel's specially binned i9-9900K, featuring 5GHz all core boost and base clock of 4GHz. This CPU is one of the most powerful Intel CPU in term of day-to-day and gaming performance but with TDP of 127W, bulky air cooler or 240mm AIO is recommended to make sure the CPU doesn't overheat, and open loop liquid cooling if you want to OC. [Jun '20 ColdSpy]
