Intel Core i9-9900K Re-Reviewed, 95-Watt TDP Results

Believing that Intel is "cheating their own spec and pushing board partners to run the i9-9900K at the default clock multiplier table, rather than at the official power spec," Hardware Unboxed has re-tested the CPU and published benchmarks of how well Intel’s flagship performs at a lower TDP. Some argue the allegations are meaningless, as the part was designed to handle higher wattages (so long as the proper cooling is in place), but the results seem to favor Ryzen 2700x fans who claim the i9 is a poor deal in comparison: at 95-watt TDP, the 9900K appears to perform similarly, but with more power and heat involved.

As we just saw with the 95-watt limit, it’s barely any faster than the Ryzen 7 2700X. In fact, in some tests it’s slower, and that’s an awful result for a CPU that costs ~70% more. This is a big issue for Intel and they’ve painted themselves into a corner here. For the 9900K to make an ounce of sense, for anyone who isn’t an extreme overclocker, it needs to run at around 70 C with a quality aftermarket cooler and for that the TDP can’t really be any higher than about 105 watts.
