The A10-7850K is a fourth generation Kaveri CPU with an integrated GPU billed as AMD’s most powerful APU when it was released in January 2014. It combines four steamroller CPU cores and eight Radeon GPU cores. Despite it’s billing, raw performance proved to be underwhelming: the base/turbo clocks run at 3.7/4.0 GHz, leading to an effective speed of 63 which is actually lower than it's predecessor: the A10-6800K (full comparison). However combined with an SSD this would provide an acceptable experience for most desktop applications. The integrated R7 graphics are around 25% better than the 8670 Graphics in the A10-6800K. The A10-7850K makes for a reasonable entry-level gaming PC or HTPC. However if processing performance, especially single threaded, is required, then the i3-4360 is far superior. [Dec '14 CPUPro]

The Intel i9-9900K is an 8 core, 16 thread, unlocked 9th generation Coffee Lake processor. It has a base / boost clocks of 3.6 / 4.7 GHz and a single-core boost of 5.0 GHz (the highest frequency achieved yet from this class of Intel CPU). It features 16 MB of cache, a 95W TDP and Intel UHD 630 graphics. The 9900K is compatible with the new Z390 chipset, and subject to a BIOS update, is also compatible with the older Z370 chipset. Aimed at users who do not wish to compromise, the i9-9900K offers the best gaming and desktop experience available at any price. Heavy workstation users should consider the Ryzen 9 3900X which is similarly priced. Comparing the overclocked 3900X shows that it is just 10% worse for gaming and desktop (sub octa-core) but around 40% better for 64-core computations. Gamers should consider the 9700K which offers identical overclocked gaming performance at a $100 USD discount. [Oct '18 CPUPro]
