GeForce 9600 GT 1GB vs Radeon HD 4750

Intro

Compare those specifications to the Radeon HD 4750, which makes use of 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 specific model. It features 640(128x5) SPUs along with 32 Texture Address Units and 16 ROPs.

Radeon HD 4750		75 Watts
GeForce 9600 GT 1GB		95 Watts
	Difference: 20 Watts (27%)

Memory Bandwidth

The GeForce 9600 GT 1GB should in theory be a small bit faster than the Radeon HD 4750 in general. (explain)

GeForce 9600 GT 1GB		57600 MB/sec
Radeon HD 4750		51200 MB/sec
	Difference: 6400 (13%)

Texel Rate

The Radeon HD 4750 will be just a bit (about 12%) faster with regards to texture filtering than the GeForce 9600 GT 1GB. (explain)

Radeon HD 4750		23360 Mtexels/sec
GeForce 9600 GT 1GB		20800 Mtexels/sec
	Difference: 2560 (12%)

Pixel Rate

The Radeon HD 4750 is a small bit (more or less 12%) better at full screen anti-aliasing than the GeForce 9600 GT 1GB, and also should be able to handle higher screen resolutions without losing too much performance. (explain)

Radeon HD 4750		11680 Mpixels/sec
GeForce 9600 GT 1GB		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.

Specifications

Memory Bandwidth: Memory bandwidth is the largest amount of information (counted in MB per second) that can be moved across the external memory interface in one second. It's calculated by multiplying the bus width by its memory speed. If it uses DDR memory, the result should be multiplied by 2 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 can be applied per second. This figure is worked out by multiplying the total number of texture units by the core clock speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the clock speed of the card. 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 of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
