Rx 480 Poor Performance

[ProdigyJC]

I just bought a Radeon Rx480 XFX GPU while before I was just running off the integrated graphics off my AMD A10 7860k APU. In Radeon Settings it says the GPU is the primary and the APU's graphics is enabled. But in AMD Overdrive it says that the GPU load is 0%(sometimes it spikes to 25% during). This is only a problem because I am getting better performance, but not what I was expecting. For example I still get frame drops when playing dolphin emulator. No better than the APU. I think AMD overdrive isn't working properly because during a heavy gaming load it's reading 10-20 degrees C while the fans are spinning. I'm going to look for a monitor so any tips or advice on this is appreciated.

Okay I got MSI afterburner reading at around 70 degrees C and in the 90 percentile during a gaming load. Not sure if that's accurate either. The fans are set to auto and are only at around 40%

Try some other games or benchmarks. Maybe the cpu is getting pushed to the max. Please note a loaded cpu will not always show 100% load if a program does not use all cores.

Emulating a different system is sometimes harder on the system than one would guess. Look at how much more was needed to emulate SNES back in the day. You could play some games on lower end, but even Pentium 1 systems over 100mhz could struggle at times(and the snes was under 10mhz). I remember N64 emulation required LOTS of power compared to the N64's specs on paper. Emulating PowerPC to run Mac apps also had a similarly high overhead.

90% is pretty decent use for a video card to be honest. You can get a 3rd opinion with GPU-Z

GPU-Z says the GPU load is spiking from 0 to 100% a lot on the video card. Should I disable the integrated graphics or does that matter? According to GPU-Z they were never used. I tested minecraft and its hard staying over 100 fps with a mid-grade GPU.

Normally onboard video should not cause much issue when not in use.

0-100 does sound like you are cpu bound.

How was the gpu use in minecraft.

I was referring to minecraft about the GPU load in the last post. I can't even break 100fps on csgo on high (not very high) settings. The CPU load on csgo is at about 50% sometimes spiking upwards to 100%. The GPU load is fluctuating between >10% and 100% constantly on afterburner and GPU-Z. The power draw is constantly going from 40w-120w on GPU-Z and afterburner reports a stable 70-80w. Overdrive pretty much reports nothing on the GPU. My PSU is a EVGA 500W 80Plus. Maybe this is it? Not enough power delivered?

I honestly think you are getting all you can out of the CPU.

It is not a very fast cpu and is most likely holding back the video card(this leads to the card dropping to 0 when it has no work to do then 100 when required again.).

I do not think you have any power issue since the APU is very power friendly(even lower without the onboard video in use).
