Intel’s Comet Lake flagship, the i9-10900K, is the fastest gaming and desktop CPU currently available. This ten-core hyperthreaded processor can easily be overclocked so that all twenty threads run at an eye-watering 5.2 GHz. Whilst its stellar performance is second to none, it comes with a premium price tag of $488 USD. The 10900K also requires a new (Z490) LGA1200 motherboard, which Intel has indicated will remain compatible with Rocket Lake CPUs which are due later this year. Whilst AMD’s competing $420 USD Ryzen 3900X and $675 USD Ryzen 3950X do have a greater number of cores, their lower clock speeds and higher memory latency handicap them in non-rendering use cases. Overall, the 10900K has a 16% effective speed advantage over both the 3900X and 3950X. Users that do a lot of rendering should investigate dedicated hardware encoders such as NVENC and Quick Sync as these are far more efficient than CPU based rendering. Comparing the 10900K and 10700K shows that, when paired with a 2060S, the 10700K offers comparable gaming performance for 20% less money.[Jun '20CPUPro]
The AMD A10-5700 is a quad-core Trinity APU (combined CPU and GPU) based on launched in Q4 of 2012. The A10-5700 is reasonably power efficient with a TDP of 65 Watts. In terms of performance the A10-5700 scores an effective speed of 68 versus the A10-6800K’s 73. Its base clock speed is 3.4 GHz which automatically turbo boosts to 4.0 GHz when needed and is sufficient for most generic desktop applications. The integrated HD 8670 Graphics are comparable to Intel's recent HD offerings. The A10-5700 offers reasonable performance at a reasonable price point. But comparing the A10-6700 and i3-4330 shows that the comparably priced 4330 is a far more compelling alternative given its almost outright advantage on every metric. [Dec '14CPUPro]
