High-resolution PBO enhancement with exceptional performance boost
High-resolution PBO enhancement with exceptional performance boost
Hopefully some 7800x3d users will join in once it drops. I'm leaning uncertain—I'll need to compare its performance to a solid 7700x first. We'll find out what microcenter offers.
It seems like you're comparing performance between CCD0 and CCD1 in games. You think the extra 64MB of L3 memory helps the CPU run faster and more consistently, especially at lower latencies, even though it might miss some high-frequency moments due to a slight slowdown around -400MHz. Your recent tests with full cores show this, but hwmonitor doesn't display the best performance differences compared to hwinfo.
Recent upload was brief, lasting around six hours across multiple games; HWmonitor and hwinfo appear reliable when CPU is fully enabled. HWmonitor shows issues with abnormal CCD settings. At 5.25GHz, Zen4 3D v-cache tends to prefer this frequency, though it's just a sample—expect a few weeks of adjustment. I've locked in -15mV on the curve optimizer as it stabilizes better than higher values.
I believe the decision hinges largely on the games you play. For MMO or large multiplayer titles where high player numbers can lead to CPU delays, 3D v-cache appears to help, as seen in my initial tests. In the long term, I think the 7900x3D could be a stronger choice because its hybrid design seems promising and it’s likely to improve further, particularly if AMD continues advancing this technology. Up to now, there’s no incentive to treat your 7950x3D as a 7800x3D; I’m also interested in seeing how other reviewers handle the 7950x3D after proper optimization—especially those who’ve spent time tuning it. Proper setup matters, not just UEFI settings. A useful note: the 7900x3D is available now at a discount of $15. I tried a pseudo 7600x3D and didn’t notice any performance difference, even though the 7600x has similar issues; it runs smoothly without extra boost clock gains over the 5.25GHz (after using hwnifo). So you essentially have a 7600x ready to go as a backup.
24 hours continuous operation with logged boosting data since Zen4 appears more precise. The 5.25GHz limit seems strict for the 3D CCD, while the non-3D CCD can handle boosts. The recent 5.875GHz boost likely came from cooler conditions—probably near a window with heavy snow last night—but 5.75GHz is a dependable clock for this processor.
these figures appear significantly more sensible compared to what was shared earlier; they likely represent the highest quality CCDs currently available. Achieving stable performance above 5.7GHz is a notable improvement over what many others claim with their Zen chips.
