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 22% effective speed advantage over the 2700X, the Ryzen 2700X offers better value for money for most users. [Oct '18 CPUPro]

MORE DETAILS

Intel’s Core i7-9700K is an unlocked 9th generation CPU, released alongside the i5-9600K and the i9-9900K. The 9700K is an 8 core, 8 thread processor based on the third iteration of Intel’s 14nm Coffee Lake architecture, which sees an increase in the number of cores available to mainstream consumers, in line with AMD’s Ryzen 7 offerings. The 9700K features 12 MB of cache, a 95W TDP and Intel UHD graphics 630. And like the other 9th generation chips, it is compatible with Intel’s new Z390 chipset as well as last years Z370 chipset (with an updated BIOS). The 9700K has a base frequency of 3.6 GHz, rising to 4.6 GHz when all 8 cores are engaged and a single core boost frequency of 4.9 GHz (compared to 3.6 GHz, 4.7 GHz and 5.0 GHz for the flagship 9900K). This translates to similar single and quad core performance to the 9900K, but due to the higher number of threads, the 9900K has around a 50% higher multi-core benchmark than the 9700K. Currently most PC games do not engage more than 4 cores, so at $420 (15% cheaper than the 9900K), the 9700K offers better value for money to gamers. If instead, great multi-core performance is a necessity, at $290, the 8 core 16 thread Ryzen 7 2700X is a more prudent choice, with a 30% higher multi-core benchmark than the 9700K.  [Oct '18 CPUPro]
