GeForce 9800 GX2 vs Radeon HD 4830 1GB

Intro

The GeForce 9800 GX2 features a GPU clock speed of 600 MHz, and the 512 MB of GDDR3 memory is set to run at 1000 MHz through a 256-bit bus. It also is comprised of 128 SPUs, 64 TAUs, and 16 ROPs.

Compare all of that to the Radeon HD 4830 1GB, which uses a 55 nm design. AMD has set the core frequency at 575 MHz. The GDDR4 memory runs at a frequency of 900 MHz on this particular model. It features 640(128x5) SPUs along with 32 Texture Address Units and 16 ROPs.

GeForce 9800 GX2 76800 Mtexels/sec
Radeon HD 4830 1GB 18400 Mtexels/sec
Difference: 58400 (317%)

Pixel Rate

The GeForce 9800 GX2 will be quite a bit (approximately 109%) faster with regards to full screen anti-aliasing than the Radeon HD 4830 1GB, and also should be able to handle higher screen resolutions without slowing down too much. (explain)

GeForce 9800 GX2 19200 Mpixels/sec
Radeon HD 4830 1GB 9200 Mpixels/sec
Difference: 10000 (109%)

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 maximum amount of information (in units of megabytes per second) that can be moved across the external memory interface within a second. It's calculated by multiplying the card's bus width by the speed of its memory. If it uses DDR RAM, the result should be multiplied by 2 once again. If it uses 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 can be applied per second. This is calculated by multiplying the total texture units of the card by the core speed of the chip. The better the texel rate, the better the 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 most pixels the video card could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
