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.

The Intel G4560 is one of the first Pentium processors to feature Hyper-threading. This means that although the G4560 only has two physical processing cores, it is able to process four threads in parallel by sharing resources between the physical cores. This typically results in a 50% performance improvement over two physical cores alone. Comparing performance between the lowest spec Kaby Lake i3 7100 and the Pentium G4560 shows that in terms of both performance and specs, very little separates them (even virtualization technology VT-d is present on the Pentium). The Pentium does lack AVX 2.0 (Advanced Vector Instructions) and it trails the i3 7100 by 400 MHz (10%) but there is no longer a clear divide between Pentiums and Core i3s. Intel have achieved an almost continuous distribution of performance levels for each price point from the cheapest Pentium to the top end i7-7700K. [Jan '17CPUPro]
We calculate effective speed which measures real world performance for typical users. Effective speed is adjusted by current prices to yield a value for money rating. Our calculated values are checked against thousands of individual user ratings. The customizable table below combines these factors to bring you the definitive list of top CPUs. [CPUPro]
