The Intel Core i5-4670K is the latest middle tier desktop processor from the fourth generation of Intel's Core range codenamed "Haswell". In terms of raw performance this processor slightly bests its predecessor the 3570K achieving approximately 10% higher server benchmark scores. In terms of real world performance the single core improvements are more relevant as more than two cores are rarely used for most typical consumer tasks and these have also improved by around 10% over the 3570K. It's not all good news though as the price increase of 14% more than offsets the performance improvements. This processor currently represents approximately the same value for money as its predecessor, the i5-3570K. [Jun '13 CPUPro]

MORE DETAILS

The i5-2500K is a second generation Sandy Bridge processor which is currently two generations old and nearly three years out of date. The many users that had the good sense to purchase this processor should feel in no hurry to upgrade as it's still no slouch, even by today's standards. The benchmark figures indicate that, even at stock clock rates, in terms of real-world performance this processor is approximately 20% slower than the best currently available, not bad considering its age. Given that the 2500K has an unlocked multiplier upping its performance by 10% with stock cooling should not pose much of a problem for the majority of owners. Here is a detailed performance comparison of the 2500K vs 4670K.  [Jul '13 CPUPro]
