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i5-2500K is a second generation Sandy Bridge processor which is currently two generations old and nearly three years out of date.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]

MORE DETAILS

The AMD A10-6800K is a Black Edition quad-core Richland APU based on second generation Bulldozer micro-architecture (codenamed Piledriver) launched in Q2 2013. It features Cayman-derived Integrated HD 8670 Graphics which are a marginal improvement on the Radeon HD 7660D graphics featured in the A10-6800K’s predecessor: the A10-5800K and which outperform the integrated graphics on comparable Intel Core i3 and i5 chips. The A10-6800K has a clock speed of 4.0 GHz, which automatically turbo boosts to 4.4 GHz when needed and can further be overclocked to 5.0 GHz on air cooling. The A10-6800K scores an effective speed of 73 which is okay, but compared to the similarly aged and priced i3-4130, it lacks in single-threaded performance. The A10-6800K is a good choice for those wanting reasonable CPU performance and integrated graphics on a budget. [Dec '14 CPUPro]
