GeForce 9600 GT 1GB vs Radeon HD 6750

Intro

Compare all of that to the Radeon HD 6750, which has a core clock frequency of 725 MHz and a GDDR5 memory frequency of 1000 MHz. It also makes use of a 128-bit bus, and uses a 40 nm design. It is comprised of 720 SPUs, 36 Texture Address Units, 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

The Radeon HD 6750 should in theory be a small bit faster than 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 a lot (approximately 25%) more effective at 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 high levels of AA is important to you, then the Radeon HD 6750 is the winner, not by a very large margin though. (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: Memory bandwidth is the largest amount of information (measured in MB per second) that can be transported past the external memory interface in one second. It is calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster 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 processed per second. This number is calculated by multiplying the total amount of texture units of the card by the core 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 processed per second.

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