Geforce GTX 680 vs Radeon HD 4350

Intro

Compare those specs to the Radeon HD 4350, which uses a 55 nm design. AMD has set the core speed at 575 MHz. The DDR2 memory runs at a speed of 500 MHz on this particular card. It features 80(16x5) SPUs along with 8 TAUs and 4 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 4350		22 Watts
Geforce GTX 680		195 Watts
	Difference: 173 Watts (786%)

Memory Bandwidth

Theoretically, the Geforce GTX 680 should perform quite a bit faster than the Radeon HD 4350 in general. (explain)

Geforce GTX 680		192256 MB/sec
Radeon HD 4350		8000 MB/sec
	Difference: 184256 (2303%)

Texel Rate

The Geforce GTX 680 should be much (about 2699%) better at anisotropic filtering than the Radeon HD 4350. (explain)

Geforce GTX 680		128768 Mtexels/sec
Radeon HD 4350		4600 Mtexels/sec
	Difference: 124168 (2699%)

Pixel Rate

If using high levels of AA is important to you, then the Geforce GTX 680 is the winner, and very much so. (explain)

Geforce GTX 680		32192 Mpixels/sec
Radeon HD 4350		2300 Mpixels/sec
	Difference: 29892 (1300%)

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 transferred past the external memory interface in a second. It is calculated by multiplying the bus width by its memory clock speed. If it uses DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, 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 texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total amount of 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 processed in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
