Base clock speed is a touch lower than with the i7-8700K, at 3.60 GHz vs. Each of the eight cores can address the entire 12 MB of 元 cache. Intel has also reduced the 元 cache amount from 16 MB to 12 MB, or 1.5 MB per core. This 8-core chip is the first Core i7 product from Intel to lack HyperThreading. The Core i7-9700K is designed to replace the i7-8700K from the product stack, at around $400. Higher clock speeds, up to 4.9 GHz Boost, also contribute to this design effort. Despite the lack of HyperThreading, Intel hopes that the two additional physical cores will make the chip faster than the i7-8700K. In a way, it has double the muscle of Core i5 quad-core processors from 2016, which are 4-core/4-thread with 6 MB of 元 cache. Intel's answer came in the form of the Core i7-9700K, which is 8-core/8-thread and has just 12 MB of 元 cache.
Configuring the die as a 6-core/12-thread wouldn't have made the cut since the underlying micro-architecture is the same. It now needed something to sell at $350–$400 that's reasonably faster than the i7-8700K. Intel hence decided to monetize it at a higher price point of $500, with the Core i9-9900K. Upon its completion, Intel's product managers may have discovered that a fully unlocked "Coffee Lake Refresh" die is also much faster than the Core i7-8700K to be sold at its price-point, owing to 33% more cores and 元 cache. Intel knew the only way out was to build a new 8-core die. Had Intel stuck to the same 6-core die and incrementally updated it with features, such as a soldered IHS and higher clocks, it would have played into AMD's game, which was probably waiting with higher-clocked SKUs based on its 8-core "Pinnacle Ridge" die. AMD managed to close the gap between its first Ryzen processors and Intel's 8th gen "Coffee Lake" processors with its new 2nd-gen Ryzen 2000-series. The company increased core counts for a second time in the past couple of years, but this time, only bolstered its expensive Core i7 and new Core i9 mainstream-desktop SKUs with more cores.
Intel introduced its 9th generation Core processor family with much fanfare earlier this month.
