GeForce 8800 GT 1GB vs Radeon HD 4350

Intro

Compare that to the Radeon HD 4350, which comes with a clock frequency of 575 MHz and a DDR2 memory frequency of 500 MHz. It also makes use of a 64-bit memory bus, and makes use of a 55 nm design. It is comprised of 80(16x5) SPUs, 8 Texture Address Units, and 4 ROPs.

Radeon HD 4350		22 Watts
GeForce 8800 GT 1GB		105 Watts
	Difference: 83 Watts (377%)

Memory Bandwidth

Theoretically, the GeForce 8800 GT 1GB should perform quite a bit faster than the Radeon HD 4350 in general. (explain)

GeForce 8800 GT 1GB		57600 MB/sec
Radeon HD 4350		8000 MB/sec
	Difference: 49600 (620%)

Texel Rate

The GeForce 8800 GT 1GB should be quite a bit (more or less 630%) more effective at texture filtering than the Radeon HD 4350. (explain)

GeForce 8800 GT 1GB		33600 Mtexels/sec
Radeon HD 4350		4600 Mtexels/sec
	Difference: 29000 (630%)

Pixel Rate

The GeForce 8800 GT 1GB should be quite a bit (approximately 317%) better at anti-aliasing than the Radeon HD 4350, and also should be able to handle higher screen resolutions better. (explain)

GeForce 8800 GT 1GB		9600 Mpixels/sec
Radeon HD 4350		2300 Mpixels/sec
	Difference: 7300 (317%)

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: Bandwidth is the maximum amount of data (in units of MB per second) that can be moved across the external memory interface in a second. It is worked out by multiplying the bus width by the speed of its memory. If the card has DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This figure is worked out by multiplying the total number of texture units of the card by the core clock 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 processed per second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
