GeForce 9600 GT 1GB vs Radeon HD 6750

Intro

Compare those specifications to the Radeon HD 6750, which has GPU core speed of 725 MHz, and 512 MB of GDDR5 RAM set to run at 1000 MHz through a 128-bit bus. It also is made up of 720 SPUs, 36 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 6750		86 Watts
GeForce 9600 GT 1GB		95 Watts
	Difference: 9 Watts (10%)

Memory Bandwidth

Performance-wise, the Radeon HD 6750 should in theory be a small bit superior to the GeForce 9600 GT 1GB overall. (explain)

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

Texel Rate

The Radeon HD 6750 should be much (about 25%) faster with regards to texture filtering than the GeForce 9600 GT 1GB. (explain)

Radeon HD 6750		26100 Mtexels/sec
GeForce 9600 GT 1GB		20800 Mtexels/sec
	Difference: 5300 (25%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon HD 6750 is superior to the GeForce 9600 GT 1GB, but not by far. (explain)

Radeon HD 6750		11600 Mpixels/sec
GeForce 9600 GT 1GB		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 max amount of information (counted in MB per second) that can be transferred across the external memory interface in one second. The number is worked out by multiplying the interface width by its memory speed. If it uses DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better 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 are applied in one 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 texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines 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 rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
