Intel’s new consumer flagship CPU for 2018 is the i9-9900K, an 8 core, 16 thread, unlocked 9th generation Intel core desktop processor. It is based on the third round of optimization of Intel’s 14nm Coffee Lake architecture, which in this iteration, yields more cores. This is a retort to AMD’s 8 core 16 thread Ryzen 7 processors that launched in Q2 2018, to fill the gap before Intel releases it’s 10nm Cannon Lake based CPUs in, perhaps, late 2019. In direct proportion to the increased number of cores, average multi-core benchmarks are around 33% higher on the 8 core 9900K than the previous generation 6 core 8700K. The i9-9900K has a base frequency of 3.6 GHz, ramping up to an all-core turbo boost frequency of 4.7 GHz and a single-core turbo boost speed of 5.0 GHz (the highest frequency achieved yet from this class of Intel CPU). It features 16 MB of cache, a 95W TDP and Intel UHD graphics 630. The 9900K is compatible with the new Z390 chipset from Intel, and subject to a BIOS update, is also compatible with the Z370 chipset. This premium CPU is expected to retail at $500, which compares to around $300 for the 8 core, 16 thread Ryzen 7 2700X. Although the 9900K has around a 16% effective speed advantage over the 2700X, the Ryzen 2700X offers better value for money for most users. [Oct '18 CPUPro]

The 8 core, 16 thread 2700X is AMD’s second generation Ryzen 7 flagship following in the wake of the Ryzen 7 1800X which continues to offer excellent multi-core value for money. This new Pinnacle Ridge processor features the Zen+ architecture with 12nm lithography compared to 14nm previously. Whilst there is no increase in the number of cores, the stock base / boost clocks appear to have received a bump up to 3.7 / 4.3 GHz from 3.6 / 4.0 GHz. The 2700X is compatible with both the new 400 series and 300 series of motherboards. Early benchmarks indicate that the 2700X has a slightly greater effective speed than the 1800X, although further benchmarks are necessary to quantify this. The expected launch price of $329 includes a Wraith Prism cooler and is in the same price bracket as the 1800X and Intel’s Coffee Lake i7-8700K. Whilst the 6 core, 12 thread 8700K beats the 2700X in single and quad core performance by about 10%, the 2700X wins on multi-core workloads. PC gaming and desktop performance is generally governed by four or less cores but the 2700X offers unbeatable value for money for workstation users. [Apr '18 CPUPro]
