GeForce 9600 GSO 768MB vs Radeon HD 4670 1GB

Intro

Compare those specifications to the Radeon HD 4670 1GB, which makes use of a 55 nm design. AMD has clocked the core frequency at 750 MHz. The GDDR4/GDDR3/DDR3/DDR2 RAM works at a speed of 1100 MHz on this specific card. 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 768MB		84 Watts
	Difference: 14 Watts (20%)

Memory Bandwidth

As far as performance goes, the GeForce 9600 GSO 768MB should in theory be a little bit superior to the Radeon HD 4670 1GB in general. (explain)

GeForce 9600 GSO 768MB		38400 MB/sec
Radeon HD 4670 1GB		35200 MB/sec
	Difference: 3200 (9%)

Texel Rate

The GeForce 9600 GSO 768MB should be a little bit (about 10%) more effective at anisotropic filtering than the Radeon HD 4670 1GB. (explain)

GeForce 9600 GSO 768MB		26400 Mtexels/sec
Radeon HD 4670 1GB		24000 Mtexels/sec
	Difference: 2400 (10%)

Pixel Rate

The GeForce 9600 GSO 768MB is a small bit (more or less 10%) more effective at full screen anti-aliasing than the Radeon HD 4670 1GB, and also should be able to handle higher screen resolutions without slowing down too much. (explain)

GeForce 9600 GSO 768MB		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 max amount of information (measured in MB per second) that can be transferred past the external memory interface in a second. The number is calculated by multiplying the card's bus width by its memory speed. In the case of DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, 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 number of texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total texture units of the card by the core speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the the core 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 rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
