GeForce GTX 260 216SP 55 nm vs Radeon HD 4850 X2 1GB

Intro

The GeForce GTX 260 216SP 55 nm uses a 55 nm design. nVidia has clocked the core speed at 576 MHz. The GDDR3 memory works at a frequency of 999 MHz on this specific model. It features 216 SPUs along with 72 Texture Address Units and 28 ROPs.

Compare all that to the Radeon HD 4850 X2 1GB, which features clock speeds of 625 MHz on the GPU, and 993 MHz on the 1024 MB of GDDR3 RAM. It features 800(160x5) SPUs along with 40 TAUs and 16 ROPs.

Radeon HD 4850 X2 1GB 250 Watts
Difference: 79 Watts (46%)

Memory Bandwidth

As far as performance goes, the Radeon HD 4850 X2 1GB should theoretically be just a bit better than the GeForce GTX 260 216SP 55 nm in general. (explain)

Radeon HD 4850 X2 1GB 127104 MB/sec
GeForce GTX 260 216SP 55 nm 111888 MB/sec
Difference: 15216 (14%)

Texel Rate

The Radeon HD 4850 X2 1GB will be quite a bit (approximately 21%) more effective at anisotropic filtering than the GeForce GTX 260 216SP 55 nm. (explain)

Radeon HD 4850 X2 1GB 50000 Mtexels/sec
GeForce GTX 260 216SP 55 nm 41472 Mtexels/sec
Difference: 8528 (21%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon HD 4850 X2 1GB is a better choice, by a large margin. (explain)

Radeon HD 4850 X2 1GB 20000 Mpixels/sec
GeForce GTX 260 216SP 55 nm 16128 Mpixels/sec
Difference: 3872 (24%)

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.

One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.

Memory Bandwidth: Memory bandwidth is the max amount of information (in units of megabytes per second) that can be transferred across the external memory interface within a second. The number is worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This number is worked out by multiplying the total amount of texture units by the core clock 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 maximum amount of pixels the video card can possibly write to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
