GeForce GTX 260 216SP 55 nm vs Radeon HD 7790

Intro

The GeForce GTX 260 216SP 55 nm has a GPU clock speed of 576 MHz, and the 896 MB of GDDR3 memory is set to run at 999 MHz through a 448-bit bus. It also is comprised of 216 SPUs, 72 Texture Address Units, and 28 ROPs.

Compare those specifications to the Radeon HD 7790, which comes with GPU core speed of 1000 MHz, and 1024 MB of GDDR5 RAM running at 1500 MHz through a 128-bit bus. It also is made up of 896 SPUs, 56 TAUs, and 16 Raster Operation Units.

Radeon HD 7790 85 Watts
GeForce GTX 260 216SP 55 nm 171 Watts
Difference: 86 Watts (101%)

Memory Bandwidth

As far as performance goes, the GeForce GTX 260 216SP 55 nm should theoretically be just a bit superior to the Radeon HD 7790 overall. (explain)

GeForce GTX 260 216SP 55 nm 111888 MB/sec
Radeon HD 7790 96000 MB/sec
Difference: 15888 (17%)

Texel Rate

The Radeon HD 7790 will be a lot (approximately 35%) more effective at texture filtering than the GeForce GTX 260 216SP 55 nm. (explain)

Radeon HD 7790 56000 Mtexels/sec
GeForce GTX 260 216SP 55 nm 41472 Mtexels/sec
Difference: 14528 (35%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 260 216SP 55 nm is superior to the Radeon HD 7790, though only just barely. (explain)

GeForce GTX 260 216SP 55 nm 16128 Mpixels/sec
Radeon HD 7790 16000 Mpixels/sec
Difference: 128 (1%)

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 maximum amount of information (in units of MB per second) that can be transported across the external memory interface in a second. The number is worked out by multiplying the card's interface width by its memory speed. If it uses DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 texture map elements (texels) that are processed in one second. This number is worked out by multiplying the total amount of texture units by the core speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units 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 rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
