3900X vs i9-9900K specifications comparison

The charts below demonstrate the difference between i9-9900K and 3900X most important features. These characteristics, together with an IPC (instructions per cycle) number, determine how well a microprocessor performs. The "Number of cores / threads" graph shows the number of cores (darker area). Lighter area on the graph corresponds to the number of extra threads, offered by Hyper-Threading technology. The "Operating frequency" chart uses dark color to represent base frequency, whereas lighter area is for additional frequency, provided by Turbo feature. Darker area on the "On-chip cache" graph is for the On-chip L2 cache. Lighter area is for the L3 cache cache. Although the L3 cache cache is usually larger than the On-chip L2 cache, it is always slower.

CPUIDs

The table below compares support for x86 extensions and technologies, as well as individual instructions and low-level features of the AMD Ryzen 9 3900X and Intel Core i9-9900K microprocessors. Information in this table was retrieved from actual processors using CPUID instruction, and we also utilized internal timer to measure CPU frequency. Be aware that all technologies, disabled in BIOS or by a virtual machine, will be shown as not supported. Different steppings of Intel processors may also have slightly different features. In rare cases, measured frequency may differ from official specifications.
