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 Core i7-7700K is Intel’s flagship Kaby Lake based CPU which is reported to have the same IPC as its predecessor, Skylake. Comparing the 7700K and 6700K shows that both average effective speed and peak overclocked speed are up by 7%. Most of the increase in average effective speed is explained by the 5% boost in base clocks from 4.0 to 4.2 GHz. The improved peak lab speed is attributable to a combination of better overclocking capacity and improvements in Intel’s speedshift technology which make the 7700K slightly more responsive. Kaby Lake also has marginally better HD 630 integrated graphics. The i7-7700K is priced similarly to the i7-6700K so for top end gaming and workstation builds, the 7700K is the clear choice for 2017. AMD’s Ryzen will release later this year so things could change at that time. [Jan '17 CPUPro]
