The graphs below show the difference between Core i9-10850K and AMD Ryzen 9 3900X most important features. These characteristics, along with an IPC (instructions per cycle) number, determine how well a microprocessor performs. The "Number of cores / threads" graph displays the number of cores (darker area). Lighter area on the graph represents the number of additional threads, provided by Hyper-Threading technology. The "Operating frequency" chart uses dark color to represent base frequency, whereas lighter area is for extra 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 i9-10850K 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.
