For those with a 7950x3d what are the max clocks you have seen? I did some testing on a single core and on the 3d cores I have never seen more than 4.9 GHZ. For the speed cores I have not seen more than 5.3 GHZ. This was testing with cinebench single core mode or using prime 95 on a single core. I want to say the clocks were advertised to boost higher than that. I saw a slight boost if I set the mobo to auto OC 3d mode which I believe set the FSB to 103%, but it was slight.
CPU utilization during gaming is vastly different.
Since I was testing out disabling the frequency CCD on my 7950X3D (
see here), I also decided to see what the clocks looked like during gaming using MSI Afterburner. MSI Afterburner polling is set to every 500ms with the graph frequency range set to between 4000MHz and 5400MHz.
The 7950X3D CCD0 (3D V-Cache CCD) has an Fmax of 5250MHz on a 100MHz bus. I have PBO enabled with CO set to -15 across all the cores.
There are favored cores while gaming. In the case of my 3D V-Cache CCD, the favored cores are 1, 4, 5, and 6. 5050MHz is the most commonly observed boost frequency. Many times these cores spike above 5050MHz to between 5100MHz and 5250MHz. Core utilization bounces between these favored cores.
