GeForce GTX 480 vs Radeon RX 470

Intro

The GeForce GTX 480 has core 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 Rasterization Operator Units.

Compare all of that to the Radeon RX 470, which uses a 14 nm design. AMD has set the core speed at 926 MHz. The GDDR5 RAM is set to run at a speed of 1650 MHz on this specific model. It features 2048 SPUs along with 128 TAUs and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 470 120 Watts
GeForce GTX 480 250 Watts
Difference: 130 Watts (108%)

Memory Bandwidth

Performance-wise, the Radeon RX 470 should in theory be just a bit superior to the GeForce GTX 480 overall. (explain)

Radeon RX 470 211200 MB/sec
GeForce GTX 480 177408 MB/sec
Difference: 33792 (19%)

Texel Rate

The Radeon RX 470 will be quite a bit (about 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 a high resolution is important to you, then the GeForce GTX 480 is a better choice, but it probably won't make a huge difference. (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: Memory bandwidth is the largest amount of data (in units of megabytes per second) that can be transported across the external memory interface in one second. It's calculated by multiplying the card's interface width by its memory speed. If the card has DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. The number is worked out 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 is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
