GeForce GTX 460 SE vs Radeon HD 4850 X2 512MB

Intro

The GeForce GTX 460 SE comes with a GPU clock speed of 650 MHz, and the 1024 MB of GDDR5 memory runs at 850 MHz through a 256-bit bus. It also is comprised of 288 Stream Processors, 48 TAUs, and 32 Raster Operation Units.

Compare all of that to the Radeon HD 4850 X2 512MB, which features a core clock frequency of 625 MHz and a GDDR3 memory speed of 993 MHz. It also makes use of a 256-bit memory bus, and uses a 55 nm design. It is made up of 800(160x5) SPUs, 40 TAUs, and 16 ROPs.

GeForce GTX 460 SE 108800 MB/sec
Difference: 18304 (17%)

Texel Rate

The Radeon HD 4850 X2 512MB is a lot (more or less 60%) more effective at texture filtering than the GeForce GTX 460 SE. (explain)

Radeon HD 4850 X2 512MB 50000 Mtexels/sec
GeForce GTX 460 SE 31200 Mtexels/sec
Difference: 18800 (60%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce GTX 460 SE is the winner, but only just. (explain)

GeForce GTX 460 SE 20800 Mpixels/sec
Radeon HD 4850 X2 512MB 20000 Mpixels/sec
Difference: 800 (4%)

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 largest amount of data (measured in MB per second) that can be moved across the external memory interface in a second. It's calculated by multiplying the card's interface width by its memory speed. In the case of DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's 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 number of texture map elements (texels) that are processed in one second. This figure is worked out by multiplying the total number of texture units by the core 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 applied in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly write to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
