GeForce GTX 580 vs Radeon HD 4350

Intro

Compare all of that to the Radeon HD 4350, which makes use of a 55 nm design. AMD has set the core speed at 575 MHz. The DDR2 RAM works at a speed of 500 MHz on this specific card. It features 80(16x5) SPUs along with 8 TAUs and 4 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 4350		22 Watts
GeForce GTX 580		244 Watts
	Difference: 222 Watts (1009%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 580 should be 2305% quicker than the Radeon HD 4350 overall, due to its higher data rate. (explain)

GeForce GTX 580		192384 MB/sec
Radeon HD 4350		8000 MB/sec
	Difference: 184384 (2305%)

Texel Rate

The GeForce GTX 580 will be much (more or less 974%) better at AF than the Radeon HD 4350. (explain)

GeForce GTX 580		49408 Mtexels/sec
Radeon HD 4350		4600 Mtexels/sec
	Difference: 44808 (974%)

Pixel Rate

The GeForce GTX 580 should be quite a bit (more or less 1511%) more effective at anti-aliasing than the Radeon HD 4350, and should be able to handle higher screen resolutions without slowing down too much. (explain)

GeForce GTX 580		37056 Mpixels/sec
Radeon HD 4350		2300 Mpixels/sec
	Difference: 34756 (1511%)

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 information (in units of MB per second) that can be moved over the external memory interface in one second. It's worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This number is calculated by multiplying the total number of 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 in a second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly record to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on quite a few 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.
