GeForce 9600 GSO 768MB vs Radeon HD 6770

Intro

Compare all that to the Radeon HD 6770, which has core speeds of 900 MHz on the GPU, and 1050 MHz on the 512 MB of GDDR5 RAM. It features 800 SPUs along with 40 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 9600 GSO 768MB		84 Watts
Radeon HD 6770		108 Watts
	Difference: 24 Watts (29%)

Memory Bandwidth

Theoretically speaking, the Radeon HD 6770 is 75% quicker than the GeForce 9600 GSO 768MB in general, due to its higher bandwidth. (explain)

Radeon HD 6770		67200 MB/sec
GeForce 9600 GSO 768MB		38400 MB/sec
	Difference: 28800 (75%)

Texel Rate

The Radeon HD 6770 should be much (more or less 36%) more effective at anisotropic filtering than the GeForce 9600 GSO 768MB. (explain)

Radeon HD 6770		36000 Mtexels/sec
GeForce 9600 GSO 768MB		26400 Mtexels/sec
	Difference: 9600 (36%)

Pixel Rate

If using a high screen resolution is important to you, then the Radeon HD 6770 is a better choice, and very much so. (explain)

Radeon HD 6770		14400 Mpixels/sec
GeForce 9600 GSO 768MB		6600 Mpixels/sec
	Difference: 7800 (118%)

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 data (in units of MB per second) that can be transferred past the external memory interface within a second. The number is worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

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