GeForce 9600 GSO 384MB vs Radeon HD 4670 1GB

Intro

Compare all of that to the Radeon HD 4670 1GB, which uses a 55 nm design. AMD has set the core speed at 750 MHz. The GDDR4/GDDR3/DDR3/DDR2 memory works at a speed of 1100 MHz on this specific model. It features 320(64x5) SPUs as well as 32 TAUs 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

Theoretically speaking, the GeForce 9600 GSO 384MB should perform a bit faster than the Radeon HD 4670 1GB overall. (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 a bit (about 10%) more effective at AF 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, not by a very large margin though. (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: Memory bandwidth is the largest amount of information (in units of MB per second) that can be transported past the external memory interface within a second. It is worked out by multiplying the card's bus width by its memory speed. If the card has DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly write to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the clock speed of the card. 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, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
