GeForce 9600 GSO 512MB vs Radeon HD 7750

Intro

Compare all of that to the Radeon HD 7750, which has a clock frequency of 800 MHz and a GDDR5 memory speed of 1125 MHz. It also uses a 128-bit memory bus, and uses a 28 nm design. It features 512 SPUs, 32 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 7750		55 Watts
GeForce 9600 GSO 512MB		90 Watts
	Difference: 35 Watts (64%)

Memory Bandwidth

In theory, the Radeon HD 7750 is 25% faster than the GeForce 9600 GSO 512MB in general, because of its greater data rate. (explain)

Radeon HD 7750		72000 MB/sec
GeForce 9600 GSO 512MB		57600 MB/sec
	Difference: 14400 (25%)

Texel Rate

The GeForce 9600 GSO 512MB is much (more or less 22%) faster with regards to AF than the Radeon HD 7750. (explain)

GeForce 9600 GSO 512MB		31200 Mtexels/sec
Radeon HD 7750		25600 Mtexels/sec
	Difference: 5600 (22%)

Pixel Rate

The Radeon HD 7750 will be quite a bit (approximately 23%) better at anti-aliasing than the GeForce 9600 GSO 512MB, and also will be able to handle higher resolutions while still performing well. (explain)

Radeon HD 7750		12800 Mpixels/sec
GeForce 9600 GSO 512MB		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 (measured in megabytes per second) that can be transferred over the external memory interface in a second. The number is worked out by multiplying the card's interface width by the speed of its memory. In the case of DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This figure is calculated by multiplying the total amount 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 handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can 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 Render Output Units by the clock 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 fill rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
