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.

The AMD Phenom II X4 955 is a quad-core processor based on the K10 micro-architecture. When it launched in Q2 of 2009, it was AMD’s fastest CPU. Given its base clock of 3.2 GHz, with appropriate cooling, this unlocked Black Edition chip can be overclocked to speeds in excess of 4 GHz. The 955’s effective speed of 63 isn’t impressive by today’s standards, but when coupled with a decent graphics card, it won't cause major bottlenecks for most games. The 955 was pitched against the high-end of Intel’s Core 2 quads, and now costs a fraction of its original list price as one would expect, however there are better alternatives on the market now.
