RX 480 vs RX 580 Comparison Review

In this RX 480 vs RX 580 comparison review, we will compare the good and bad of these two graphics cards from the same manufacturer AMD.


The AMD Radeon RX 480 is dubbed as the first graphics card that feature the 14nm Polaris architecture. It was released on June of 2016 and was based on the 3rd revision of the Graphics Core Next architecture.

While the AMD Radeon RX 580 is from the new AMD Radeon RX 500 series it is the updated version of the RX 400. It was released on April 2017 and was based on the 14nm Pascal architecture.

GPU Specifications

The RX 480 GPU is codenamed Ellesmere XT while the RX 580 is codenamed Polaris 20 XTX. RX 480 as a core speed of 1120 MHz lower than the 1257 MHz of the RX 580. These core speed can be boosted to 1266 MHz for the 480 and 1340 MHz on the 580 which is greater than the latter.

In this comparison we used the 8gb variant of both RX 480 and RX 580. Memory speed of both are the same at 2000 MHZ. Memory bus of these are the same at 256bit. Both use the same memory type GDDR5 and they have the same memory bandwidth at 256GB/sec.

These two are pretty much the same in terms of graphics processing unit specifications.

In terms of shader processing units both registers at 2304. Actual shader performance is both at 100%. Both have the same 14nm technology.

Texture mapping units are the same on both 480 and 580 at 144. Texture rate on the 480 lags the 580 at 161.3 GTexel/s compared to the 181 GTexel/s of the 580.

Render output units of both cards are the same at 32. In terms pixel rate the 480 is edged by the 580, it has only 35.8 GPixel/s compared to the 40.2 GPixel/s of the 580.

Game Performance

The RX 480’s performance according to benchmarks, that it is 10% faster that the GTX 970 at 4k resolution. But it can’t beat the performance of the R9 390. It is expected have its performance between R9 290 and R9 290x.

While the RX 580 performance according to benchmark is similar to GTX 1060. It is faster than the model it replaced by 8% and it is also better by 8-15% with RX 570.

We tested these two graphics cards side by side on the following games: CSGO, Fortnite, PUBG, GTA V, LOL, Battlefield 1, The Witcher 3, DOTA 2, WOW, World of Tanks and Minecraft.

Here is the result of RX 480 compared to the RX 580 in terms of game FPS. In the game CSGO, it is 6% slightly better, in League of Legends it is 12% better, and for World of Tanks its is 6% better compared to the RX 580.

On the other hand, here is the result of RX 580 compared to the RX 480 in terms of game FPS. In the game PUBG it is 17% slightly better FPS, in The Witcher 3 it is 16% better, in World of Warcraft it is 13% better and lastly in Minecraft it is 17% better in game FPS than the RX 480.

Final Verdict

On this comparison this is very tricky to pick the winner because it is very close. But for me ill pick the RX 580 as the winner for these reasons. First it is the newer GPU between the two. Second it slightly edged the RX 480 in our real-world test in the game FPS. It has better game FPS on 4 of the 12 games we tested compared to the 3 only of the RX 480.

This is the end of our RX 480 vs RX 580 comparison review. Hope you liked it!
