The 7950X cores aren't in a saved state.
Hey! It seems like most key tasks are handled, but you're questioning whether it's actually functioning properly. From the desktop view, no cores appear as idle, and in the resource monitor there are no cores marked as parked. It might only pause when games are running or when the system isn't fully utilizing all cores. In BIOS, you've only adjusted RAM settings, and you're using the newest chipset. The power mode is set to Balanced, and the Xbox Game Bar is active but not visible from here.
You can also adjust affinity manually by assigning it from CPU 0 to CPU 15 for each executable, and also raise the priority to high. Alternatively, you might prefer using non-SMT* cores such as CPU0, 2, 4, 6, 8, 9, 11, and 13 to minimize latency further. In reality, cores are grouped—each core contains multiple logical/smt units (like core0 and core1), so you don’t have a strict separation. Setting affinity on one core’s CPU still affects the other logical/smt units, provided background tasks aren’t assigned to higher cores and they run at normal priority. This helps prevent threads from starting up unexpectedly.
I've conducted extensive testing with my 7950x3D and using the 'prefer cache' option is significantly more effective than leaving it in auto or as 'prefer driver.' It can be challenging to locate, but the results are worth it. The system also dynamically activates cores as required, so background processes or applications exceeding CCD0 capacity will release them. It's more efficient than I anticipated overall, though I'm uncertain if the reviewers fully updated the firmware outside of techpowerup.
For gaming purposes, I'd rely on cache settings. For productivity, a 7950x would suffice. If you balance both, go with auto or the preferred driver configuration. AMD's design includes more than just the driver—UEFI components assess CPU power draw and RAM usage to decide if it's a high-performance task. If the system supports over 8c/16t, it activates the second CCD and enables dynamic unparking. Your motherboard should offer additional options to fine-tune performance. Also, the 'prefer cache' setting automatically strips the 3D v-cache performance optimizer driver. If you're unsure about its priority, this setting effectively disables it without removing the driver entirely—it just removes it from system devices when not in use.
