GeForce GTS 450 vs Radeon HD 4350

Intro

Compare that to the Radeon HD 4350, which features a core clock frequency of 575 MHz and a DDR2 memory frequency of 500 MHz. It also features 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 GTS 450		106 Watts
	Difference: 84 Watts (382%)

Memory Bandwidth

Theoretically, the GeForce GTS 450 should perform much faster than the Radeon HD 4350 in general. (explain)

GeForce GTS 450		57728 MB/sec
Radeon HD 4350		8000 MB/sec
	Difference: 49728 (622%)

Texel Rate

The GeForce GTS 450 should be quite a bit (approximately 445%) more effective at anisotropic filtering than the Radeon HD 4350. (explain)

GeForce GTS 450		25056 Mtexels/sec
Radeon HD 4350		4600 Mtexels/sec
	Difference: 20456 (445%)

Pixel Rate

If using a high resolution is important to you, then the GeForce GTS 450 is the winner, by a large margin. (explain)

GeForce GTS 450		12528 Mpixels/sec
Radeon HD 4350		2300 Mpixels/sec
	Difference: 10228 (445%)

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 data (measured in megabytes per second) that can be transported past the external memory interface within a second. It is worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR type memory, the result should 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 AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total number of texture units 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 in a second.

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