AMD Radeon RX 480, 3DMark analysis

Published: 25th Jun 2016, 22:26 GMT

I made this post to give you some insight on Polaris 10 synthetic performance, or more importantly what RX 480 is capable of.

In the following charts I gathered hundreds (around 330) results of RX 480 3DMark scores.

I separated the data in three groups, average, median and maximum values. If you are looking for the most common benchmarks results of RX 480 then you should be looking at medians, as average scores also include overclocking results. By the way, all results are of 8GB model.

Let’s start with the clocks. The highest observed clock was 1379 MHz (most samples oc to 1330-1350 MHz), with median of 1266 MHz (stock boost clock). The memory can be overclocked up to 2200 MHz, although most samples are clocked up to 2100 MHz.

If we compare average values to the results we posted more than a week ago, then we are observing 1% decrease in Extreme, 6% decrease in Ultra and 1% increase in Performance preset.

Now, let’s compare median values to maximum values, to see overclocking potential on reference cards:

It appears that reference card can be overclocked to 114% of its stock performance. However no one knows how much potential should be expected from non-reference designs.

The next stop is CrossFire scaling in Fire Strike. Let me remind you those are Graphics Points, which are always higher than Overall scores in CrossFire tests. That said, we are not looking at ‘pure gaming CrossFire scaling’.

What we are looking here for are bottlenecks, and those seem to be present in Ultra test (2160p resolution).

Finally I have two more charts for you.

The first one is showing all results in a graph. You can hover your mouse over each result to see what score was achieved with specific clock. Sometimes when the clocks are set too high, card will downclock to safer values, which generates lower scores.

The last chart is showing median values and maximum observed values. This is as accurate as it gets, before we see official values.

That’s it for now. I hope you will find this post interesting.
