In terms of raw single-core performance the flagship AMD FX-8350 is lagging behind intel's processor line-up by over two generations. The PassMark Single Thread scores for the i5-2500K vs the FX-8350 are 1863 to 1520 which shows that in terms of raw per-core processing the FX-8350 is lagging the two year old i5 by 23%. Where the AMD FX makes up is on multi-core performance, with a score of 9156 vs 6745, the AMD leads the Intel 2500K by 36% making it the far more capable multi-threaded server orientated performer. The 8350 is also cheaper but significantly more power hungry which counts strongly against it as a server proposition. The FX-8350 could be a good fit for specific server use cases but for general consumer use, which is single and dual core intensive, Intel's two year old i5-2500K delivers better performance.

The hex-core i5-8500 hails from Intel’s eighth generation of Coffee Lake processors, known for featuring a higher number of cores at each SKU than in previous generations and their refinement of the 14nm architecture as seen in 6th and 7th generation processors. At an estimated price of $184 it offers good multi-core value for money. Its quad core performance nearly rivals the more expensive i7-7700K (the 2017 CPU of choice for many top-end gamers). However based on preliminary benchmarks, the i5-8500 is only marginally faster (2% greater effective speed) than the i5-8400 which is also a recent and competitively priced hex-core Coffee Lake processor. Also, like the i5-8400, the 8500 features 9MB of L3 cache and a frugal TDP of 65W, leaving not much to choose between them. As is the case of all Coffee Lake processors, currently the only motherboards that the 8500 can be paired with feature Intel’s high-end Z370 chipset for overclocking. However, alternative and more suitable 300 series motherboards are long overdue and expected to be available soon. [Mar '18CPUPro]
