I am losing around 250 points in 3D mark CPU Benchmark and i need to restart to full points of CPU.

I have 9600K OC to 4.8GHZ.

I am losing around 250 (6450 CPU Score ) Points 3D Mark Timespy CPU benchmark and Intel Burner benchmark it gives me 198.56 GFLOPS in benchmark.

To gain the points i need to restart the computer and i have to make sure that i do not run anything other than the benchmark application otherwise if i run anything different i.e game, internet, or multimedia than i will get the same score above otherwise when i restart and run the benchmark application at the get go than i get on 3D Mark Timespy 6650 points and Intel Burner benchmark i get around 206.5 GFLOPS.

Can anyone guide what is the issue.

My GPU is fine and getting same result ,however, i only lose CPU performance when am running CPU and need to restart to get full score.

Would like to be useful here. But realistically you are using a computer, a computer made for more than running benchmarks. Besides the lack of need to be constantly benchmarking it post first log in, and thing with even the slightest memory leak or anything that does any kind of polling (even Windows itself with a bunch of its active tools are going to cause minor and steady drops in perf when compared to a fresh boot, nothing having been running before that benchmarking session.

I'm going to have to agree, this is a non issue whatsoever.

Compulsive benchmarkers (like myself) that post to HWBOT and try to make 3dmark leaderboards are constantly doing fresh reboot, disabling all unnecessary windows background processes, uninstalling/disabling all unnecessary software/windows defender, running several benchmarks back-to-back to get that one best run.

A variance which you describe of 3-4% is totally normal based on windows activating more background processes/services after you've used a few programs, even if you close those programs the services may still be running. Windows also does a ton of stuff under the hood whenever it feels like. The honest advice given most frequently to make sure your hardware is working and configured correctly is exactly what you're doing, a fresh reboot and run benchmarks before any applications are opened.

You're doing just fine, and you shouldn't worry about it in the slightest.



To clarify, windows has dozens of services that are only ever activated on demand - i.e. you open a program that needs a windows service, it was dormant after a fresh reboot until you started a program that needs it. That alone is a reasonable source of the performance discrepancy, however applications may activate and leave background tasks running as well that unless you explicitly find and end in task manager will also affect benchmark scores.

Personally, I'd only worry if my scores were 10%+ lower than expected, and if they weren't resolved upon a fresh reboot of windows.

I tinker a lot so sometimes when my scores change I throw in a spare drive and do a fresh windows install and 99/100 times the scores are perfectly fine, as in my current windows install has become bloated due to how much stuff I've installed/uninstalled/etc.
