Question 3d Mark CPU score has dropped by nearly a 1000 points in the last month using Ryzen 7800X3D ?

[mrjenkins44]

So back in late may I built a new PC (7800x3d, 3080ti) and got a 19404 average score in 3d Mark Timespy (normal). Over the months, the score has degraded to between 19050-19200. The GPU score is about the same, but the CPU has dropped by nearly a 1,000 points, from 14095 to 13021. I have made no changes to my system at all, other than updating my BIOS. I find this drop to be weirdly drastic, since I've done nothing to the system other than install new games.

Perhaps Gigabyte's BIOS fix for the vsoc issue caused the CPU to perform a little less, I dunno. My performance in games is the same. Is this something you would investigate, or just leave be? I'm comparing an image of two different runs (one from today, and one from may), the only difference I an find is CPU core VID is slightly higher (1.018750 vs .993750) in the higher score.

I have the CPU at 100% in power settings.

While I wouldn't worry about it a whole lot the two things that'd leap to mind to check is that your DRAM is still running the same as it should and you might compare the average clock frequency 3dmark reported in the respective runs to see if that's any different.

Perhaps the old BIOS did not have the 1.30V CPU SoC voltage mod and (hopefully) the new BIOS does. That might explain your lower benchmark score. The CPU is no longer boosting as hard.

Check to see if you've got the latest BIOS. Mine was updated three times in a fortnight. You don't want your CPU to burn up due to overvoltage during boosting. The x3D CPUs are particularly susceptible. Luckily my 7950X (non 3D) is still OK after 7 months.

Stop worrying about benchmarks and enjoy using the PC instead.

Also not changing anything in your system hopefully doesn't mean that you didn't do any windows updates, those can have an effect on performance, just as installing more apps over time, a worked in system will have more background stuff going on than a clean install.

I did think of suggesting the OP Roll Back to an earlier Restore Point and run the benchmark, but there's no telling if it would be possible to revert to the latest config.

Each time a security vulnerability is exposed in CPU hardware, Microsoft releases yet another Update which slows down the computer. Shades of Spectre and Meltdown five years ago.

Not much point in worrying unless the system's started to crash.
