Comparing technical specs and benchmarks

AMD Ryzen 9 3950X
VS
Intel Core i9-10900KF
AMD's 2019 desktop processor of the year is the most powerful 3rd Gen Ryzen solution yet. It is based on the 7nm process technology, provides 16 cores and 32 threads, which makes it one of the main competitors of Intel's high-performance CPUs such as the Core i9-9980XE. The flagship AMD 3950X OEM processor has a clock speed of 3.5 GHz, which in Turbo mode can automatically increase by 1200 MHz to 4.7 GHz. The unlocked multiplier allows for custom overclocking, however, you need to take into account that the heat dissipation of the model is 105 W, so for overclocking you need to choose a suitable cooling system (the cooler is not originally included in the OEM package). The "engine" does not provide an integrated graphics core, but it has acquired an impressive supply of cache memory (64 MB of the third level), is compatible with the AM4 mass platform, supports the accelerated PCI Express 4.0 bus and DDR4-3200 RAM.

The processor Intel Core i9-10900KF is developed on the technology node and architecture Comet Lake. Its base clock speed is 3.70 GHz, and maximum clock speed in turbo boost 5.30 GHz. The processor contains 10 processing cores supported DDR4-2933 memory. To make a right choice for processor upgrading, please get familiar with the detailed technical specifications and benchmark testing results.
