In terms of performance, the Intel Core i9-10900F scored 5747 points in the single-core test and 29363 points in the multi-core test. Now, for 10-core, 20-wire chips that are optimized to run at 170W conservative power settings and run up to 224W peak power compared to unlocked "K" series CPUs), these scores seem very reasonable. Once you start comparing yourself with your competitors, everything will change.
R9 4900HS has eight cores and sixteen threads, base frequency 3.0GHz, maximum acceleration frequency is 4.3GHz, based on TSMC 7nm process.
