GeForce 9600 GSO 384MB vs Radeon HD 4670 1GB

Intro

Compare those specifications to the Radeon HD 4670 1GB, which features a clock speed of 750 MHz and a GDDR4/GDDR3/DDR3/DDR2 memory frequency of 1100 MHz. It also uses a 128-bit bus, and uses a 55 nm design. It is made up of 320(64x5) SPUs, 32 Texture Address Units, and 8 ROPs.

	Difference: 3200 (9%)

Texel Rate

The GeForce 9600 GSO 384MB should be a small bit (more or less 10%) better 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

The GeForce 9600 GSO 384MB should be just a bit (approximately 10%) better at AA than the Radeon HD 4670 1GB, and also should be capable of handling higher resolutions while still performing well. (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 maximum amount of information (measured in megabytes per second) that can be moved past the external memory interface within a second. It is calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster 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 are processed in one second. This number is worked out by multiplying the total amount of texture units by the core speed of the chip. The higher the texel rate, the better the video 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 most pixels that the graphics chip could possibly record to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
