GeForce 9600 GT 1GB vs Radeon HD 5830

Intro

Compare all of that to the Radeon HD 5830, which makes use of a 40 nm design. AMD has set the core speed at 800 MHz. The GDDR5 memory is set to run at a speed of 1000 MHz on this particular card. It features 1120(224x5) SPUs as well as 56 TAUs and 16 Rasterization Operator Units.

GeForce 9600 GT 1GB		95 Watts
Radeon HD 5830		175 Watts
	Difference: 80 Watts (84%)

Memory Bandwidth

Theoretically speaking, the Radeon HD 5830 is 122% faster than the GeForce 9600 GT 1GB in general, due to its higher bandwidth. (explain)

Radeon HD 5830		128000 MB/sec
GeForce 9600 GT 1GB		57600 MB/sec
	Difference: 70400 (122%)

Texel Rate

The Radeon HD 5830 should be quite a bit (about 115%) better at texture filtering than the GeForce 9600 GT 1GB. (explain)

Radeon HD 5830		44800 Mtexels/sec
GeForce 9600 GT 1GB		20800 Mtexels/sec
	Difference: 24000 (115%)

Pixel Rate

The Radeon HD 5830 should be a lot (approximately 23%) faster with regards to AA than the GeForce 9600 GT 1GB, and also capable of handling higher screen resolutions more effectively. (explain)

Radeon HD 5830		12800 Mpixels/sec
GeForce 9600 GT 1GB		10400 Mpixels/sec
	Difference: 2400 (23%)

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 maximum amount of information (in units of megabytes per second) that can be transferred across the external memory interface in a second. It's worked out by multiplying the bus width by its memory speed. In the case of DDR memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
