GeForce 9600 GT 1GB vs Radeon HD 6770

Intro

Compare all of that to the Radeon HD 6770, which has GPU clock speed of 900 MHz, and 512 MB of GDDR5 memory running at 1050 MHz through a 128-bit bus. It also features 800 SPUs, 40 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 9600 GT 1GB		95 Watts
Radeon HD 6770		108 Watts
	Difference: 13 Watts (14%)

Memory Bandwidth

In theory, the Radeon HD 6770 will be 17% faster than the GeForce 9600 GT 1GB overall, because of its higher bandwidth. (explain)

Radeon HD 6770		67200 MB/sec
GeForce 9600 GT 1GB		57600 MB/sec
	Difference: 9600 (17%)

Texel Rate

The Radeon HD 6770 will be quite a bit (approximately 73%) more effective at texture filtering than the GeForce 9600 GT 1GB. (explain)

Radeon HD 6770		36000 Mtexels/sec
GeForce 9600 GT 1GB		20800 Mtexels/sec
	Difference: 15200 (73%)

Pixel Rate

If using a high screen resolution is important to you, then the Radeon HD 6770 is superior to the GeForce 9600 GT 1GB, by far. (explain)

Radeon HD 6770		14400 Mpixels/sec
GeForce 9600 GT 1GB		10400 Mpixels/sec
	Difference: 4000 (38%)

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 max amount of information (counted in megabytes per second) that can be moved over the external memory interface within a second. It's worked out by multiplying the interface width by its memory clock speed. If it uses DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total texture units by the core speed of the chip. The higher the texel rate, the better the video card will be at handling 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 the video card can possibly record to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
