GeForce 9600 GT 1GB vs Radeon HD 6770

Intro

Compare those specs to the Radeon HD 6770, which makes use of a 40 nm design. AMD has set the core frequency at 900 MHz. The GDDR5 RAM is set to run at a speed of 1050 MHz on this specific card. It features 800 SPUs along with 40 TAUs and 16 Rasterization Operator 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

Theoretically speaking, the Radeon HD 6770 should be 17% faster than the GeForce 9600 GT 1GB in general, due to its greater bandwidth. (explain)

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

Texel Rate

The Radeon HD 6770 should be quite a bit (approximately 73%) more effective at anisotropic 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 running with 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: Bandwidth is the maximum amount of information (measured in MB per second) that can be moved past the external memory interface within a second. It's worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
