Review on 🚀 Intel Core i9-9900K Octa-Core Processor | 3.60 GHz | 8 GT/s DMI | 5 GHz Overclocking Speed | 14 nm by Goro Shimada ᠌

It's sad that the race with AMD has gone down the path of increasing the number of cores, and not the performance per core. Most of the useful software (engineering programs, databases, browsers, various scripts, user interface, etc.) will not benefit from additional cores. The main gain will be in multi-threaded number grinders, for which the HEDT platform is more suitable, much better optimized for such tasks, incl. having a 4-channel memory bus. Well, we are waiting for the programs to "start to utilize all available cores", which many people really want now . As of today, the 9900K has the best per-core performance, runs Windows 7, has stable drivers, and doesn't have a lot of weird hidden restrictions like running AVX commands half at a time. So I chose it, despite the fact that I consider 8 cores rather a minus. The system was assembled with the expectation of low temperatures and reliability. Motherboard - Asus Prime Z370-A II with 8-phase VRM on DrMOS (this is the best we could find, because there are no drivers for Windows 7 for Z390). Memory - Trident Z F4-3200C14D-16GTZ by G. Skill, 4x8 GB. Cooler - Fractal Design Celsius S24. I overclocked almost nothing, but set the boost frequency to 5 GHz when working from 1 to 4 cores, 4.8, 4.7, 4.6 and 4.5 GHz when working from 5 to 8 cores, respectively, and a long-term consumption limit of 125 watts. The result in the CPU-Z test is + 3% in single-thread and -9% in multi-thread from the nominal 9900K. Passmark shows a single-threaded throughput of 3050 points. In the worst case (Small FFT test), the frequency is reset to 4 GHz. With a typical load (h264-10b encoder, Blend test) - remains at the specified level (4.5 GHz for all cores). In all tests, the voltage does not exceed 1.25 V, the temperature is kept around 60-63 degrees. I did not touch the core voltage. Although it is possible to win back 50-70 millivolts, it is quite difficult to do this while maintaining dynamic tuning. Decided it was better to have a margin of stability.
