GeForce 9600 GT 1GB vs Radeon HD 4750

Intro

Compare all of that to the Radeon HD 4750, which makes use of a 40 nm design. AMD has clocked the core speed at 730 MHz. The GDDR5 RAM is set to run at a frequency of 800 MHz on this particular 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

Theoretically, the GeForce 9600 GT 1GB should be a small bit faster than the Radeon HD 4750 overall. (explain)

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

Texel Rate

The Radeon HD 4750 should be a bit (about 12%) better at anisotropic 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

If using a high resolution is important to you, then the Radeon HD 4750 is a better choice, though only just barely. (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 maximum amount of information (measured in megabytes per second) that can be transferred past the external memory interface in a second. The number is calculated by multiplying the interface width by its memory clock speed. If the card has DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This figure is worked out by multiplying the total amount of texture units by the core 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 per second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
