GeForce GTX 580 vs Radeon HD 5770

Intro

The GeForce GTX 580 makes use of a 40 nm design. nVidia has set the core speed at 772 MHz. The GDDR5 memory is set to run at a frequency of 1002 MHz on this card. It features 512 SPUs as well as 64 TAUs and 48 ROPs.

Compare that to the Radeon HD 5770, which uses a 40 nm design. AMD has set the core frequency at 850 MHz. The GDDR5 RAM runs at a speed of 1200 MHz on this card. It features 800(160x5) SPUs along with 40 Texture Address Units and 16 Rasterization Operator Units.

Radeon HD 5770 76800 MB/sec
Difference: 115584 (151%)

Texel Rate

The GeForce GTX 580 is a lot (approximately 45%) better at anisotropic filtering than the Radeon HD 5770. (explain)

GeForce GTX 580 49408 Mtexels/sec
Radeon HD 5770 34000 Mtexels/sec
Difference: 15408 (45%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 580 is a better choice, by a large margin. (explain)

GeForce GTX 580 37056 Mpixels/sec
Radeon HD 5770 13600 Mpixels/sec
Difference: 23456 (172%)

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 maximum amount of data (in units of MB per second) that can be transferred past the external memory interface within a second. It's worked out by multiplying the card's interface width by its memory clock speed. In the case of DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
