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 3950X
and Intel Core i9-10900KF 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.
