AMD Ryzen 9 5950X, AMD Radeon RX 6700 XT x 1, 32768 MB, 64-bit Windows 10}www.3dmark.com
Moat of my tests are done whilst I was testing GPU settings, I'll need to look for one where I actually ran the CPU test. Although my own RAM is far worse, only DDR4-3200 cl14 so not really comparable to the DDR4-3866 cl14 used on the 12900K.
Probably OC 5950X, this doesn't tell much. It's unlikely 3dmark would run at 4950 Mhz on a 5950x default because the core scaling isn't bad in 3dmark. Typical gaming clock speed is below 4950 Mhz.
