GeForce 9600 GSO 384MB vs Radeon HD 4670 1GB

Intro

Compare those specs to the Radeon HD 4670 1GB, which makes use of a 55 nm design. AMD has set the core frequency at 750 MHz. The GDDR4/GDDR3/DDR3/DDR2 RAM runs at a speed of 1100 MHz on this specific model. It features 320(64x5) SPUs along with 32 Texture Address Units and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 4670 1GB		70 Watts
GeForce 9600 GSO 384MB		84 Watts
	Difference: 14 Watts (20%)

Memory Bandwidth

In theory, the GeForce 9600 GSO 384MB will be 9% quicker than the Radeon HD 4670 1GB overall, because of its greater data rate. (explain)

GeForce 9600 GSO 384MB		38400 MB/sec
Radeon HD 4670 1GB		35200 MB/sec
	Difference: 3200 (9%)

Texel Rate

The GeForce 9600 GSO 384MB will be just a bit (about 10%) faster with regards to texture filtering than the Radeon HD 4670 1GB. (explain)

GeForce 9600 GSO 384MB		26400 Mtexels/sec
Radeon HD 4670 1GB		24000 Mtexels/sec
	Difference: 2400 (10%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce 9600 GSO 384MB is superior to the Radeon HD 4670 1GB, but it probably won't make a huge difference. (explain)

GeForce 9600 GSO 384MB		6600 Mpixels/sec
Radeon HD 4670 1GB		6000 Mpixels/sec
	Difference: 600 (10%)

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 largest amount of data (in units of megabytes per second) that can be transferred across the external memory interface within a second. The number is worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher 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 amount of texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total number of texture units by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
