Intel’s Core i7-9700K is an unlocked 9th generation CPU, released alongside the i5-9600K and the i9-9900K. The 9700K is an 8 core, 8 thread processor based on the third iteration of Intel’s 14nm Coffee Lake architecture, which sees an increase in the number of cores available to mainstream consumers, in line with AMD’s Ryzen 7 offerings. The 9700K features 12 MB of cache, a 95W TDP and Intel UHD graphics 630. And like the other 9th generation chips, it is compatible with Intel’s new Z390 chipset as well as last years Z370 chipset (with an updated BIOS). The 9700K has a base frequency of 3.6 GHz, rising to 4.6 GHz when all 8 cores are engaged and a single core boost frequency of 4.9 GHz (compared to 3.6 GHz, 4.7 GHz and 5.0 GHz for the flagship 9900K). This translates to similar single and quad core performance to the 9900K, but due to the higher number of threads, the 9900K has around a 50% higher multi-core benchmark than the 9700K. Currently most PC games do not engage more than 4 cores, so at $420 (15% cheaper than the 9900K), the 9700K offers better value for money to gamers. If instead, great multi-core performance is a necessity, at $290, the 8 core 16 thread Ryzen 7 2700X is a more prudent choice, with a 30% higher multi-core benchmark than the 9700K.  [Oct '18 CPUPro]

MORE DETAILS

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]
