GeForce 9600 GSO 512MB vs Radeon HD 6750 1GB

Intro

Compare all of that to the Radeon HD 6750 1GB, which has GPU clock speed of 725 MHz, and 1024 MB of GDDR5 RAM set to run at 1000 MHz through a 128-bit bus. It also is comprised of 720 SPUs, 36 TAUs, and 16 ROPs.

GeForce 9600 GSO 512MB		90 Watts
	Difference: 4 Watts (5%)

Memory Bandwidth

The Radeon HD 6750 1GB, in theory, should perform a bit faster than the GeForce 9600 GSO 512MB overall. (explain)

Radeon HD 6750 1GB		64000 MB/sec
GeForce 9600 GSO 512MB		57600 MB/sec
	Difference: 6400 (11%)

Texel Rate

The GeForce 9600 GSO 512MB will be just a bit (approximately 20%) more effective at AF than the Radeon HD 6750 1GB. (explain)

GeForce 9600 GSO 512MB		31200 Mtexels/sec
Radeon HD 6750 1GB		26100 Mtexels/sec
	Difference: 5100 (20%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon HD 6750 1GB is a better choice, though not by far. (explain)

Radeon HD 6750 1GB		11600 Mpixels/sec
GeForce 9600 GSO 512MB		10400 Mpixels/sec
	Difference: 1200 (12%)

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 largest amount of data (measured in MB per second) that can be moved across the external memory interface in one second. It is calculated by multiplying the bus width by its memory clock speed. If it uses DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The higher this number, the better the graphics card will be at handling 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 that the graphics chip could possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
