GeForce GTX 660 vs Radeon HD 4350

Intro

Compare all that to the Radeon HD 4350, which features clock speeds of 575 MHz on the GPU, and 500 MHz on the 512 MB of DDR2 memory. It features 80(16x5) SPUs as well as 8 Texture Address Units and 4 Rasterization Operator Units.

Radeon HD 4350		22 Watts
GeForce GTX 660		140 Watts
	Difference: 118 Watts (536%)

Memory Bandwidth

In theory, the GeForce GTX 660 should perform quite a bit faster than the Radeon HD 4350 in general. (explain)

GeForce GTX 660		144192 MB/sec
Radeon HD 4350		8000 MB/sec
	Difference: 136192 (1702%)

Texel Rate

The GeForce GTX 660 will be quite a bit (more or less 1604%) better at anisotropic filtering than the Radeon HD 4350. (explain)

GeForce GTX 660		78400 Mtexels/sec
Radeon HD 4350		4600 Mtexels/sec
	Difference: 73800 (1604%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 660 is the winner, by far. (explain)

GeForce GTX 660		23520 Mpixels/sec
Radeon HD 4350		2300 Mpixels/sec
	Difference: 21220 (923%)

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 largest amount of data (measured in megabytes per second) that can be transferred across the external memory interface in one second. It's calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better 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 is calculated by multiplying the total texture units by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
