Early Q3 of 2019 welcomes the Ryzen 9 3900X, AMD’s current top of the range, third generation Ryzen flagship which raises the bar for 64-core processing on desktop CPUs. This is AMD’s first Ryzen 9 processor and it is a 12-core, 24-thread CPU based on their latest 7nm Zen 2 microarchitecture. The 3900X has a boost/base clock of 3.8/4.6 GHz, 64 MB of L3 cache (double the L3 on the rest of 3000 series), support for 3200 MHz DDR4 system memory and a TDP of 105W. All this, plus a Wraith Prism cooler, at a very reasonable launch price of $499 USD. By comparison, Intel’s 8-core, 16 thread i9-9900K is available for $479 USD (and requires a cooler: $30+ USD). Benchmarks illustrate that the overclocked 3900X leads by a whopping 41% for 64-core processing but that the 9900K maintains a 10% lead for gaming, desktop and other sub octa-core tasks. The 3900 memory controller is significantly improved over previous Ryzen iterations and shows a better write throughput than the lower spec 3000 models, but it still shows relatively high latency which adversely impacts gaming. In terms of 64-core performance at this price point, there is no threat from Intel. The only real competitor is the upcoming (Q4, 2019) 16-core, 32-thread 3950X ($749 USD). The Ryzen 9 3900X is compatible with the new PCIe 4.0 enabled X570 motherboard via an AM4 socket, as well as 400 and 300 series motherboards. ^{[Jul '19 CPUPro]}

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]}
