Radeon HD 4850 X2 512MB vs Radeon HD 5830

Intro

The Radeon HD 4850 X2 512MB has a core clock speed of 625 MHz and a GDDR3 memory frequency of 993 MHz. It also uses a 256-bit memory bus, and uses a 55 nm design. It is comprised of 800(160x5) SPUs, 40 Texture Address Units, and 16 Raster Operation Units.

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

Radeon HD 4850 X2 512MB 127104 MB/sec
Difference: 896 (1%)

Texel Rate

The Radeon HD 4850 X2 512MB should be a small bit (about 12%) better at anisotropic filtering than the Radeon HD 5830. (explain)

Radeon HD 4850 X2 512MB 50000 Mtexels/sec
Radeon HD 5830 44800 Mtexels/sec
Difference: 5200 (12%)

Pixel Rate

The Radeon HD 4850 X2 512MB should be quite a bit (about 56%) better at FSAA than the Radeon HD 5830, and also should be capable of handling higher screen resolutions more effectively. (explain)

Radeon HD 4850 X2 512MB 20000 Mpixels/sec
Radeon HD 5830 12800 Mpixels/sec
Difference: 7200 (56%)

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 maximum amount of data (counted in megabytes per second) that can be transferred past the external memory interface in one second. It's worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the core 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 lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
