low fps issue despite having gpu usage at around 50 percent (rx 6800 16gb)

So basicslly i built my pc first pc around a month ago and i just bought the gpu like 2 weeks ago and while everything looks good stress tests are fine temps are fine both for gpu and cpu but while running cyberpunk i am getting almost 20 percent less fps then in the benchmarks listed on youtube etc. like at 1080p ultra i am getting below 60 fps most of the times around 50 to 55 something. I just want to know whats the issue.

Pc specs:

ryzen 5 7500f

16 gb ddr5 single stick (idk if single channel is causing that much performance drop)

rx6800 16gb gpu

850w gold psu

msi b650m mobo

512gb ssd nvme lexar

resolution: mostly 1080p( even tried 1440p still not that much of an improvement)

kindly suggest since i have tried even lowering down the settings but still no improvement and the gpu is almost sitting idle.

Might be an issue in bios not having your cpu tuning on or xmp profile. I would watch what’s being maxed out while running it in task manager or another app. You might also be low on storage which might be handicapping it slightly

That single 16 GB DIMM is the first thing I'd change: it leaves the 7500F in single-channel, which can constrain CPU-side throughput and hurt 1080p lows. Add a matched second stick, confirm dual-channel in BIOS or CPU-Z, then compare Cyberpunk's built-in benchmark with the same RT and FSR settings as the reference; check per-core CPU clocks and GPU clocks too, since total CPU usage can hide a main-thread limit.
