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]

MORE DETAILS

The 8-core, 16-thread Ryzen 7 3700X hails from the middle of AMD’s latest range of 7nm silicon Zen 2 CPUs. The new processors are launched alongside the new X570 chipset, whilst still being backward compatible with 300 and 400 series motherboards. They are also PCIe 4.0 enabled, allowing double the data transfer speeds compared to PCIe 3.0. The 3700X has a boost clock of 4.4 GHz, 32 MB of L3 cache, supports 3200 MHz DDR4 memory and has a power draw of just 65W TDP. At an entry price of $329 USD, it is positioned to offer superb multi-core value for money. Out of the box, the 3700X, 3600X and 3600 achieve similar quad core speeds, which is important for gamers. In addition, the 3700X, with its 16 threads really excels at multi-core processing, achieving a 25% multi-core speed advantage over the 12 threaded 3600X. Early benchmarks rank the 3700X just a few places behind Intel’s 8-core, 16-thread i9 9900K with a 10% lower peak overclocked benchmark. However, it cannot be ignored that the 3700X is about $150 USD (32%) cheaper and includes a cooler unlike the 9900K. [Jul '19 CPUPro]
