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 Ryzen 5 1600X is the flagship processor from AMD's latest generation of Ryzen 5 processors which feature the Zen architecture. Following on from last month's release of the Ryzen 7 series, the Ryzen 5 series is positioned as a less expensive mid-performance alternative to Intel's i5 mainstream offerings. Once again, AMD excels in multi-core technology. Like the Ryzen 5 1600, the 1600X features 6 cores and 12 threads, but has roughly 11% higher clock speeds (out of the box) for a 14% premium. Like all Ryzen CPUs the 1600X is unlocked. The 1600X is the only Ryzen 5 CPU with a TDP of 95W, the 1600, 1500X and 1400 all have 50% lower power consumption of 65W. Due to its high thread count, UserBenchmarks show that at stock clocks the 1600X outperforms the i7-7700k on multi-threaded tasks by 23%, but it lags behind by 23% for single and 14% for quad-core performance. The 1600X is priced keenly at $249 so a more appropriate CPU comparison is the i5-7600k where the 1600X wins on stock multi-core by a whopping 81%. The 1600X does represent great value for workstation users that also game but its $30 cheaper sibling, the 1600 (non x version), which includes a cooler and has great overclocking potential out of the box is arguably the the value king in this segment. [Apr '17 CPUPro]
