Anyone made this leap fr the 10900k and can comment if it made things any different
I’m doing it because my old msi z490 board seems stuck at gpu 4x and I want full 4x on 4 nvme
I run at 4.9ghz on all cores now and do some rendering uses too so dropping to 16 threads isn’t as nice for that purpose
Edit my eye is on the msi z690-a pro and actually the 12900kf which appears to be a beast
Any thoughts
EDIT: i forget the specifics now, but i did get some decent gains going from 10900k to 12900k at least with ddr5 5200.. i think with the aero in vr it was something like 10 fps better.. then going to 6400mhz ram from 5200 gave me another 2-3 fps. I now sit at around 52 fps with the aero at say san fran with clear skies and the 3080 ti video card with the openxr toolkit and fov. rendering on.
I can’t comment on that specific CPU jump, but I did want to mention that the i9-12900k is limited to 4800 with DDR5.
Also, if you want to upgrade and can afford it I say go for it. You can wait for newer technology, but the minute you buy something there will still be newer technology right around the corner. You can spend your life waiting for the next best thing.
Since you do rendering, I’d hold off if your current system is working. Raptor Lake/13th Gen should be out in less than 3 months, and while it’s looking like 10-25% speed increase over 12900K for lightly threaded stuff, early leaked benchmarks (of non-optimized preproduction CPUs) indicate it could be well over 30% faster for massively parallel tasks like 3D renders.
Are you GPU or CPU limited right now? I use VR with a 10850K @ 4.8GHz and 3080 and am pretty much never CPU limited at 2600x2600 per eye VR resolution and high/ultra mix settings, so in my case a CPU upgrade would not be worth it.
True. At least according to Intel’s CPU specs which has nothing to do with your motherboard. I too have RAM capable of higher speeds, but it runs at 4800.
If other conditions were the same, and PCIe bandwidth were only x4, the impact on frame rate would be less than 5% compared to x16. (If it were x1, the drop would only be about 10%.)
In other words, PCIe link multipliers contribute very little to frame rates, and are only a viable option if content loading into VRAM is frequent, and x4 is sufficient for the vast majority of games. However, this is not to say that running at x16 is a no-brainer.
However, system updates that involve PCIe changes often involve a multitude of changes, and the issue is not split up cleanly enough to be debatable, only PCIe bandwidth.
However, the focus for speed improvements is certainly not there.
