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]

MORE DETAILS

The AMD Phenom II X6 1055T was the second in a long line of X6's, each successive revision received a small clock speed boost. The 1055T was clocked at 2.8 GHz base and 3.3 GHz turbo. The 1100T was the fastest X6 and has a base/turbo clock of 3.3/3.7 GHz. Comparing the 1055T and 1100T shows that the two processors have a very similar performance profile, both excelling at multi-core workloads and both showing relative weakness in single, and dual-core workloads. In todays market the bar has been raised several notches especially for single and dual core workloads but the 1055T still puts in a relatively strong multi-core performance which is roughly on a par with an Ivy Bridge i5-3570K. [Mar '14 CPUPro]
