GeForce GTX 580 3GB vs Radeon R9 270X

Intro

The GeForce GTX 580 3GB uses a 40 nm design. nVidia has clocked the core frequency at 772 MHz. The GDDR5 memory runs at a frequency of 1002 MHz on this card. It features 512 SPUs as well as 64 Texture Address Units and 48 Rasterization Operator Units.

Compare all that to the Radeon R9 270X, which comes with core speeds of 1000 MHz on the GPU, and 1400 MHz on the 2048 MB of GDDR5 RAM. It features 1280 SPUs as well as 80 TAUs and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon R9 270X 180 Watts
GeForce GTX 580 3GB 244 Watts
Difference: 64 Watts (36%)

Memory Bandwidth

In theory, the GeForce GTX 580 3GB should perform a bit faster than the Radeon R9 270X in general. (explain)

GeForce GTX 580 3GB 192384 MB/sec
Radeon R9 270X 179200 MB/sec
Difference: 13184 (7%)

Texel Rate

The Radeon R9 270X is much (about 62%) faster with regards to anisotropic filtering than the GeForce GTX 580 3GB. (explain)

Radeon R9 270X 80000 Mtexels/sec
GeForce GTX 580 3GB 49408 Mtexels/sec
Difference: 30592 (62%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 580 3GB is superior to the Radeon R9 270X, but it probably won't make a huge difference. (explain)

GeForce GTX 580 3GB 37056 Mpixels/sec
Radeon R9 270X 32000 Mpixels/sec
Difference: 5056 (16%)

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 max amount of data (measured in megabytes per second) that can be transported over the external memory interface within a second. It's worked out by multiplying the card's bus width by its memory speed. If it uses DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics card will be at handling 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 the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
