GeForce GTS 450 vs Radeon HD 4350

Intro

Compare those specifications to the Radeon HD 4350, which makes use of a 55 nm design. AMD has set the core frequency at 575 MHz. The DDR2 RAM is set to run at a speed of 500 MHz on this specific model. It features 80(16x5) SPUs along with 8 TAUs and 4 ROPs.

Radeon HD 4350		22 Watts
GeForce GTS 450		106 Watts
	Difference: 84 Watts (382%)

Memory Bandwidth

Theoretically speaking, the GeForce GTS 450 should be 622% quicker than the Radeon HD 4350 overall, because of its higher bandwidth. (explain)

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

Texel Rate

The GeForce GTS 450 will be much (more or less 445%) better at texture 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 running with high levels of AA is important to you, then the GeForce GTS 450 is superior to the Radeon HD 4350, and very much so. (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: Bandwidth is the maximum amount of data (in units of megabytes per second) that can be transported past the external memory interface in one second. The number is worked out by multiplying the card's bus width by its memory clock speed. If the card has DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the video 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 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 fill rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
