Unusual Benchmark Results

[DaveJaVous]

I ran a benchmark and had a rather unusual result, saying that my 4-year-old A8-5600K was in the top 8% of CPUs and my brand new RX 480 was in the bottom 20% of GPUs.

 

I've been having a few odd problems with my RX 480, one of which I had a previous post. I'm certain that the underlying problem at fault is still there:

Can anyone shed light on why an RX480 would have such shockingly poor results?

And why does my A8-5600K have a similar bench score to an i7 6700K?

 

I'm completely confused

It can be: 

 

1) Driver issues. Hard to diagnose precisely without several samples. 

2) some kind of throttling, Temp, Voltage, Power usage, etc. 

3) The 480 underperforming could be due to CPU bottleneck (remember AMD DX11 drivers are highly reliant on single core performance). 

4) The Above expectations in your CPU score could be due to having a GPU, and not using the iGP, the power delivery is fully dedicated to the CPU but i didn't heard of any CPU choking on power. (this requires testing to find out). 

 

5) Are you sure you are reading this right?. The percentile may be referred to "relative performance agains Same CPU available records on the site". Not "all the CPU's in the world". 

 

6) An apu cpu performing the same as a 6700K cpu? Either the bench is not CPU intensive AT ALL or it's choking so hard on the gpu that (/Emo on) in the end it doesnt even matter. (/Emo off)
