The high-end hex core, 12 thread i7-8700 is second in Intel’s line up of 8th generation Coffee Lake CPUs that witnesses an increase in the number of cores at each SKU, as well as further refinement on the 14nm architecture as seen in the 6th and 7th generations. The i7-8700 features a TDP of 65W, 12MB of L3 Cache and 16 PCIe lanes. Although the 8700 has a base clock of 3.2 GHz it has an all core boost of 4.3 GHz and a single core boost of 4.6 GHz. These are unusually high clocks for a non-K SKU, Intel have historically clocked their non-K SKUs around 10% lower than the flagship K variants but with Coffee Lake, the 8700 is almost a match for a stock 8700K. Priced at $320, the i7-8700 offers exceptional single, quad and multi-core processing power to the mainstream market but unfortunately a new 300 series chipset will also need to be factored into the purchase. AMD’s comparably priced Ryzen 7 1700X is an 8 core 16 thread processor which is around 20% faster at multi-threaded tasks, but has around 20% slower single and quad core performance so the choice between these two processors is use case dependant but generally favours Intel for most desktop users whose workloads are typically single or dual core bound. ^{[Oct '17 CPUPro]}

The 3950X is the 16 core, 32 thread Ryzen 3 flagship. Although this CPU offers server levels of multi-core encoding performance, there are relatively few, if any, consumer use cases for the 3950X. Streamers are better off using dedicated hardware such as NVENC which encodes far more efficiently than any CPU. Gamers are better served by low latency gaming CPUs such as the 9600K for a fraction of the price. For example, comparing these two PCs shows that the 3950X build offers less than half the gaming performance. The only rational reason to put a 3950X in a gaming build is in exchange for sponsorship money. ^{[Feb '21 CPUPro]}
