GeForce GTX 480 vs Radeon RX 470

Intro

The GeForce GTX 480 has core clock speeds of 700 MHz on the GPU, and 924 MHz on the 1536 MB of GDDR5 RAM. It features 480 SPUs as well as 60 TAUs and 48 ROPs.

Compare all of that to the Radeon RX 470, which comes with GPU clock speed of 926 MHz, and 8192 MB of GDDR5 memory set to run at 1650 MHz through a 256-bit bus. It also is made up of 2048 Stream Processors, 128 Texture Address Units, and 32 Raster Operation Units.

GeForce GTX 480 177408 MB/sec
Difference: 33792 (19%)

Texel Rate

The Radeon RX 470 is much (more or less 182%) faster with regards to texture filtering than the GeForce GTX 480. (explain)

Radeon RX 470 118528 Mtexels/sec
GeForce GTX 480 42000 Mtexels/sec
Difference: 76528 (182%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 480 is the winner, though only just barely. (explain)

GeForce GTX 480 33600 Mpixels/sec
Radeon RX 470 29632 Mpixels/sec
Difference: 3968 (13%)

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: Bandwidth is the largest amount of information (in units of MB per second) that can be transferred 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 type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
