GeForce GTX 260 vs Radeon HD 5830

Intro

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

Compare all of that to the Radeon HD 5830, which features GPU core speed of 800 MHz, and 1024 MB of GDDR5 RAM set to run at 1000 MHz through a 256-bit bus. It also features 1120(224x5) SPUs, 56 Texture Address Units, and 16 ROPs.

GeForce GTX 260 111888 MB/sec
Difference: 16112 (14%)

Texel Rate

The Radeon HD 5830 should be a lot (approximately 22%) better at AF 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 high levels of AA 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 max amount of information (measured in megabytes per second) that can be moved across the external memory interface in a second. The number is calculated by multiplying the card's interface width by its memory speed. If it uses DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly write to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units 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 fill rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
