Well, just finished testing with 32 Gb ddr4 ram. Yes, ram DO make a difference.
With 8 Gb, what I noticed is that only e-cores work at full speed, like I mentioned before. Balance is roughly 80-100% workload for e-cores, 5-20% for p-cores. What I noticed also is that p-cores workload is a bit more when pc is like in âidleâ mode (no other activity but Shotcut, not even mouse moves). This would confirm that 8 Gb of ram is a bottleneck. Ram usage being around 90%.
With 32 Gb ram, difference is QUITE noticeable. Balance between e-cores and p-cores is much better by far: e-cores and p-cores workload was around 50-70% each, meaning cpu was working almost at full speed (around 70% globally all along). Even surprised me when temp reached 80°C which I wasnât expecting at all (first time with my new rig: I had to correct cooling settings in emergency !).
Ram usage was around 25% though so around 8Gb also. So maybe 10-12 Gb would be enough for cpu to handle all processes at the same time without having to make room for other recurrent processes almost all the time. Recurrent processes, from what Iâm understanding, seem to be handled by e-cores exclusively. And p-cores workload donât seem to reach high levels without e-cores âcoordinationâ. Therefore, ram amount being important in my opinion.
Well at least thatâs my understanding
