The i7-2600K Sandy Bridge processor is two generations old and nearly three years out of date. The numerous owners of this superb processor should feel in no hurry to upgrade as it's still one of the fastest consumer processors, even by today's standards. The benchmark figures indicate that in terms of real-world performance this processor is only 5% slower than the third generation Ivy Bridge i7-3770K, not bad considering its age. That said new buyers will find both better energy efficiency and marginal performance improvements elsewhere[Feb '12 CPUPro]

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]
