High-resolution PBO enhancement with exceptional performance boost
High-resolution PBO enhancement with exceptional performance boost
7950x3D with just CCD0 (3D v-cache CCD) enabled which can be shown with task manager, note the L3 cache. Comparably, this is just CCD1 (non-3D CCD) enabled. Now I haven't seen boost clocks this high or even close to this high on CCD0 with a fully enabled 7950x3D. Comparably, I'd (occasionally) see a 5.45GHz CCD0 boost and a 6.1GHz CCD1 boost, but never +5.7GHz on CCD0. Now its possible that there's going to be binning between the 7800x3D and 7950x3D's 3D v-cache CCD, but this is some impressive stuff. Note that this is a +200MHz -15mV PBO curve optimizer setup, so results may vary. Never expected CCD0 to hit this high, where my previous boosts were maybe 5.55GHz. The major difference I noticed between testing CCD0 and CCD1 only was minimum framerates in the games I tested, which were Warframe, Sea of Thieves, and Planetside 2. I didn't take specific measurements, but between me staring at the framerate and just playing, I noticed far less dips/stutters. Note I'm on a 4K 240Hz display with an OC'd RTX 4090. Anyone else have similar boosting characters of their 7900x3D and 7950x3D? I've tested down to 2c/4t on CCD0, to include a 12c/12t 7900x3D simulated.
It might have helped to turn off one CCD, allowing the remaining ones more flexibility for PBO. The HWMonitor isn't tracking PBO data; using hwinfo would provide better information.
The 7600x3D setup appears less powerful. This reflects when #3 and #5 cores are turned off, resulting in the 1,1,0,1,0,1,1,1 arrangement.
hwmonitor appears to clash with zen 4. It frequently asserts my 7700x operates above 6ghz—though it once claimed near 7—but consistently stays below 5.55ghz. No matter how much I adjust, it doesn’t reach the numbers. It’s possible levet is mistaken about the PBO data. The mismatch also shows up in other resource monitors.
I've noticed readings around 10-11GHz, which is clearly a doubled measurement. Testing Division 2 today appears to trigger stronger boosting effects. I'm adding hwinfo for verification, since that makes sense. Division 2 seems to be the top single benchmark for boosting so far. It might even perform better at 1080p compared to 4K because it increases frame rate (~150 to ~330 fps).
HWmonitor is incorrect, it doesn't understand what's happening with Zen 4 CPUs.
I'm focusing on figuring out if the 7800x3D outperforms the 7900x3D or 7950x3D, as those last two need extensive adjustments to work well. The HWmonitor's incorrect boost readings complicate things because the key issue is whether adding a second CCD reduces boost clock speeds for the 3D v-cache. If the optimizer runs perfectly (including cache preferences and other settings), then if the extra CCD doesn't block the 3D CCD from reaching its full potential, it could ultimately be more advantageous in the long term.
