GeForce 9600 GT 512MB vs Radeon HD 4750

Intro

The GeForce 9600 GT 512MB has clock speeds of 650 MHz on the GPU, and 900 MHz on the 512 MB of GDDR3 RAM. It features 64 SPUs along with 32 Texture Address Units and 16 ROPs.

Compare those specifications to the Radeon HD 4750, which uses a 40 nm design. AMD has set the core speed at 730 MHz. The GDDR5 RAM runs at a frequency of 800 MHz on this particular model. It features 640(128x5) SPUs along with 32 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 4750 75 Watts
GeForce 9600 GT 512MB 95 Watts
Difference: 20 Watts (27%)

Memory Bandwidth

In theory, the GeForce 9600 GT 512MB will be 13% quicker than the Radeon HD 4750 in general, because of its higher data rate. (explain)

GeForce 9600 GT 512MB 57600 MB/sec
Radeon HD 4750 51200 MB/sec
Difference: 6400 (13%)

Texel Rate

The Radeon HD 4750 is a little bit (about 12%) more effective at texture filtering than the GeForce 9600 GT 512MB. (explain)

Radeon HD 4750 23360 Mtexels/sec
GeForce 9600 GT 512MB 20800 Mtexels/sec
Difference: 2560 (12%)

Pixel Rate

The Radeon HD 4750 will be a small bit (more or less 12%) better at AA than the GeForce 9600 GT 512MB, and also should be capable of handling higher screen resolutions while still performing well. (explain)

Radeon HD 4750 11680 Mpixels/sec
GeForce 9600 GT 512MB 10400 Mpixels/sec
Difference: 1280 (12%)

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.

Memory Bandwidth: Memory bandwidth is the largest amount of data (in units of MB per second) that can be moved over the external memory interface within a second. The number is worked out by multiplying the bus width by its memory clock speed. If the card has DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

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