atom's benchmarks are with stock clocks & without tuning PowerMizer. The benchmarks I provided above are with a mild & usable overclock on both the 290X and 980, with optimal PowerTune and PowerMizer settings respectively.
For the 290X:
For the 980:
For Nvidia you'll have to add the following options to xorg.conf to make that nvidia-settings command work:
For the 290X:
Code:
od6config --set core=1050,mem=1375,power=50,temp=95,fan=100
For the 980:
Code:
nvidia-settings -a GPUPowerMizerMode=1 \
-a GPUFanControlState=1 \
-a GPUCurrentFanSpeed=100 \
-a GPUGraphicsClockOffset[3]=350 \
-a GPUMemoryTransferRateOffset[3]=400
For Nvidia you'll have to add the following options to xorg.conf to make that nvidia-settings command work:
Code:
Option "Coolbits" "12"
Option "RegistryDwords" "PerfLevelSrc=0x2222"
