GeForce GTX 480 vs Radeon HD 4850 X2 1GB

Intro

The GeForce GTX 480 has a GPU core speed of 700 MHz, and the 1536 MB of GDDR5 RAM runs at 924 MHz through a 384-bit bus. It also is made up of 480 Stream Processors, 60 TAUs, and 48 Raster Operation Units.

Compare that to the Radeon HD 4850 X2 1GB, which uses a 55 nm design. AMD has set the core frequency at 625 MHz. The GDDR3 RAM is set to run at a speed of 993 MHz on this particular card. It features 800(160x5) SPUs along with 40 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

In theory, the GeForce GTX 480 is 40% faster than the Radeon HD 4850 X2 1GB overall, because of its higher bandwidth. (explain)

GeForce GTX 480 177408 MB/sec
Radeon HD 4850 X2 1GB 127104 MB/sec
Difference: 50304 (40%)

Texel Rate

The Radeon HD 4850 X2 1GB is just a bit (more or less 19%) faster with regards to anisotropic filtering than the GeForce GTX 480. (explain)

Radeon HD 4850 X2 1GB 50000 Mtexels/sec
GeForce GTX 480 42000 Mtexels/sec
Difference: 8000 (19%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GTX 480 is a better choice, by a large margin. (explain)

GeForce GTX 480 33600 Mpixels/sec
Radeon HD 4850 X2 1GB 20000 Mpixels/sec
Difference: 13600 (68%)

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: Bandwidth is the largest amount of information (counted in megabytes per second) that can be transported over the external memory interface in one second. It's worked out by multiplying the card's interface width by its memory speed. If the card has DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster 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 applied per second. This number is calculated by multiplying the total texture units by the core clock speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
