Question clear, the 5800x offers higher IPC which usually means better efficiency. But if AMD boosts power more, it could offset that gain. My 3900x uses 140W for 7000 points in Cinebench, while I lowered it to 80W and got 6500 points—only a 10% drop in score. It seems it might depend on testing conditions. Are others tried this? Or how about a 3950x versus 3900x? Under similar workloads, the 3950x matches the 3900x in power draw but runs faster due to less aggressive core pacing, boosting efficiency per watt. Overall, the 3900x likely outperforms at fixed power limits, though the 3950x edges out in efficiency.
Your 3900x CCX OC to 4.5 reaches up to 150W occasionally, while in games it stays between 50-75W depending on CPU usage.
Only managed a 3900X performance drop under three weeks; missed out on 5800X and 5900X, plus the i7 and i9 chips were tough to secure. It needs an auto overclock, I’m still figuring things out before doing it manually. Draws 138W at 4.4 GHz with a 138W rating, and it’s not the best cooling solution compared to the 3900X. If you find a 5800X, it should be more efficient and cooler.
Without the OC it would consume around 100W? I don’t think adding the OC is really necessary.
