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, 9MB 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 AMD Ryzen 7 1700X isn't due for release until next week but two of our users has already submitted benchmarks. Comparing the quad and single core scores from our samples shows a relative 4.3% boost on the single core score so it’s possible that turbo wasn’t fully engaged (12% turbo boost expected). These preliminary results are seriously impressive as they put Zen’s IPC between 0% and 9% below Intel’s Kaby Lake. Even in the worst case scenario these results are still impressive. Comparing Intel’s $1,000 6900K and the 1700X shows that AMD delivers comparable performance for half the price! A shake-up of the CPU market will unfold as Zen rolls out. If Ryzen CPUs can overclock to 4.6+ GHz they will likely dominate the entire market putting a very welcome end to the monotonous tick-tock of recent years. [Feb '17 CPUPro]
