GeForce 9600 GT 1GB vs Radeon HD 5670

Intro

Compare those specs to the Radeon HD 5670, which uses a 40 nm design. AMD has set the core frequency at 775 MHz. The GDDR5 memory works at a frequency of 1000 MHz on this specific card. It features 400(80x5) SPUs as well as 20 Texture Address Units and 8 Rasterization Operator Units.

GeForce 9600 GT 1GB		57600 MB/sec
	Difference: 6400 (11%)

Texel Rate

The GeForce 9600 GT 1GB is quite a bit (about 34%) faster with regards to AF than the Radeon HD 5670. (explain)

GeForce 9600 GT 1GB		20800 Mtexels/sec
Radeon HD 5670		15500 Mtexels/sec
	Difference: 5300 (34%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce 9600 GT 1GB is the winner, by a large margin. (explain)

GeForce 9600 GT 1GB		10400 Mpixels/sec
Radeon HD 5670		6200 Mpixels/sec
	Difference: 4200 (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.

Specifications

Memory Bandwidth: Memory bandwidth is the largest amount of information (measured in megabytes per second) that can be moved across the external memory interface in one second. It's calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total texture units by the core speed of the chip. The better 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 most pixels the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
