GeForce 9600 GSO 512MB vs Radeon HD 7750

Intro

Compare all of that to the Radeon HD 7750, which features clock speeds of 800 MHz on the GPU, and 1125 MHz on the 1024 MB of GDDR5 memory. It features 512 SPUs along with 32 Texture Address Units and 16 Rasterization Operator 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

Theoretically speaking, the Radeon HD 7750 should be a lot faster than the GeForce 9600 GSO 512MB in general. (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 (approximately 22%) more effective at anisotropic filtering 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 should be quite a bit (more or less 23%) more effective at anti-aliasing than the GeForce 9600 GSO 512MB, and also should be capable of handling higher screen resolutions better. (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 largest amount of data (in units of megabytes per second) that can be transported over the external memory interface within a second. The number is calculated by multiplying the bus width by its memory speed. In the case of DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
