Maximizing Ryzen iGPU Performance on 7850U (alien.top)

submitted 1 year ago by [email protected] to c/[email protected]

10 comments fedilink hide all child comments

Just installed my 7840U mainboard. 3D Mark Time Spy is getting around 1700, which is low for the 780m.

Running Unigine Valley I am getting 1500mhz core in Afterburner and Adrenalin saids that I am using 18w.

Is there anything I can try to get my time spy score up?

I've turned off Memory Integrity in Windows

I've done the BIOS setting that allocates RAM to the iGPU

You said you’re using just one DIMM in another reply, which could contribute to this.

Besides that, I have no trouble getting ~30W TDP under heavy GPU load. Afterburner reports GPU temperature at ~70 degrees Celsius (though I’d take it with a grain of salt because many tools don’t seem to support 7040 very well yet). Was your chip throttling? You can try running a CPU benchmark and see if you get expected results. FYI, I got >9000 CPU score in Time Spy, >2000 in Cinebench R15 loop, and >5200 in Cinebench R20 loop.
