GeForce 8600 GS (OEM) vs Radeon HD 5830

Intro

Compare all of that to the Radeon HD 5830, which uses a 40 nm design. AMD has set the core speed at 800 MHz. The GDDR5 RAM works at a frequency of 1000 MHz on this particular model. It features 1120(224x5) SPUs along with 56 Texture Address Units and 16 ROPs.

GeForce 8600 GS (OEM)		8640 Mtexels/sec
	Difference: 36160 (419%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon HD 5830 is superior to the GeForce 8600 GS (OEM), and very much so. (explain)

Radeon HD 5830		12800 Mpixels/sec
GeForce 8600 GS (OEM)		4320 Mpixels/sec
	Difference: 8480 (196%)

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.

Specifications

Memory Bandwidth: Bandwidth is the max amount of information (measured in MB 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 the speed of its memory. In the case of DDR memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher 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 can be applied per second. This number is calculated by multiplying the total number of texture units by the core clock speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
