The AMD Phenom II X6 1100T was the last, in a long line of Phenom II X6's. The series went 1045T, 1055T, 1065T, 1075T, 1090T and finally 1100T. Each successive release was clocked slightly higher ending with the 1100T which had a base/turbo clock speed of 3.3/3.7 GHz. The X6 has six processing cores and demonstrates very good multi-core performance but it is less able to handle single and dual core workloads, which is what the majority of consumer desktop computing requires. The X6 series were good overclockers with the ability to boost stock clocks by around 20%. Comparing the 1100T to the similarly priced i5-2400 shows that Intel's mid-range Sandy Bridge processor, which was released just a month after the 1100T, was around 8% faster for single and dual core workloads but slower by a staggering 30% for multi-core workloads.

In terms of raw single-core performance the flagship AMD FX-8350 is lagging behind intel's processor line-up by over two generations. The PassMark Single Thread scores for the i5-2500K vs the FX-8350 are 1863 to 1520 which shows that in terms of raw per-core processing the FX-8350 is lagging the two year old i5 by 23%. Where the AMD FX makes up is on multi-core performance, with a score of 9156 vs 6745, the AMD leads the Intel 2500K by 36% making it the far more capable multi-threaded server orientated performer. The 8350 is also cheaper but significantly more power hungry which counts strongly against it as a server proposition. The FX-8350 could be a good fit for specific server use cases but for general consumer use, which is single and dual core intensive, Intel's two year old i5-2500K delivers better performance.
