GeForce GTX 260 vs Radeon HD 5830

Intro

The GeForce GTX 260 has clock speeds of 576 MHz on the GPU, and 999 MHz on the 896 MB of GDDR3 memory. It features 192 SPUs along with 64 Texture Address Units and 28 Rasterization Operator Units.

Compare those specifications to the Radeon HD 5830, which comes with a clock frequency of 800 MHz and a GDDR5 memory speed of 1000 MHz. It also makes use of a 256-bit bus, and makes use of a 40 nm design. It is made up of 1120(224x5) SPUs, 56 TAUs, and 16 Raster Operation Units.

Radeon HD 5830 175 Watts
GeForce GTX 260 182 Watts
Difference: 7 Watts (4%)

Memory Bandwidth

In theory, the Radeon HD 5830 is 14% quicker than the GeForce GTX 260 overall, due to its higher data rate. (explain)

Radeon HD 5830 128000 MB/sec
GeForce GTX 260 111888 MB/sec
Difference: 16112 (14%)

Texel Rate

The Radeon HD 5830 will be quite a bit (more or less 22%) more effective at anisotropic filtering than the GeForce GTX 260. (explain)

Radeon HD 5830 44800 Mtexels/sec
GeForce GTX 260 36864 Mtexels/sec
Difference: 7936 (22%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GTX 260 is superior to the Radeon HD 5830, and very much so. (explain)

GeForce GTX 260 16128 Mpixels/sec
Radeon HD 5830 12800 Mpixels/sec
Difference: 3328 (26%)

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 (counted in megabytes per second) that can be transported over the external memory interface in a second. It is calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
