The i7-2600K Sandy Bridge processor is two generations old and nearly three years out of date.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 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 '17 CPUPro]

Processor Rankings (Price vs Performance) December 2017 CPU Rankings.

Welcome to our desktop CPU comparison. We calculate effective speed which measures real world performance for typical consumers. Effective speed is adjusted by price to yield a value for money rating which is geared towards gamers. Calculated values don't always paint the whole picture so we check them against hundreds of individual user ratings. The customizable table below combines these factors and more to bring you the definitive list of top CPUs. [CPUPro]
