Radeon RX 480 4GB vs Radeon RX 570

Intro

The Radeon RX 480 4GB comes with a GPU core speed of 1120 MHz, and the 4096 MB of GDDR5 memory runs at 1750 MHz through a 256-bit bus. It also features 2304 Stream Processors, 144 Texture Address Units, and 32 ROPs.

Compare that to the Radeon RX 570, which features core speeds of 1168 MHz on the GPU, and 1750 MHz on the 4096 MB of GDDR5 memory. It features 2048 SPUs along with 128 TAUs and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

Both cards have exactly the same memory bandwidth, so in theory they should perform the same. (explain)

Texel Rate

The Radeon RX 480 4GB will be a bit (more or less 8%) better at texture filtering than the Radeon RX 570. (explain)

Radeon RX 480 4GB 161280 Mtexels/sec
Radeon RX 570 149504 Mtexels/sec
Difference: 11776 (8%)

Pixel Rate

The Radeon RX 570 should be a small bit (more or less 4%) more effective at anti-aliasing than the Radeon RX 480 4GB, and will be capable of handling higher resolutions without losing too much performance. (explain)

Radeon RX 570 37376 Mpixels/sec
Radeon RX 480 4GB 35840 Mpixels/sec
Difference: 1536 (4%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Memory Bandwidth: Memory bandwidth is the max amount of information (measured in megabytes per second) that can be transported past the external memory interface in one second. It's worked out by multiplying the bus width by its memory speed. If it uses DDR memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly record to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
