GeForce GTX 460 vs Radeon HD 4350

Intro

Compare those specifications to the Radeon HD 4350, which features a GPU core clock speed of 575 MHz, and 512 MB of DDR2 memory running at 500 MHz through a 64-bit bus. It also is made up of 80(16x5) Stream Processors, 8 TAUs, and 4 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 4350		22 Watts
GeForce GTX 460		150 Watts
	Difference: 128 Watts (582%)

Memory Bandwidth

In theory, the GeForce GTX 460 should be 980% quicker than the Radeon HD 4350 in general, due to its greater bandwidth. (explain)

GeForce GTX 460		86400 MB/sec
Radeon HD 4350		8000 MB/sec
	Difference: 78400 (980%)

Texel Rate

The GeForce GTX 460 will be a lot (about 722%) more effective at AF than the Radeon HD 4350. (explain)

GeForce GTX 460		37800 Mtexels/sec
Radeon HD 4350		4600 Mtexels/sec
	Difference: 33200 (722%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 460 is a better choice, and very much so. (explain)

GeForce GTX 460		16200 Mpixels/sec
Radeon HD 4350		2300 Mpixels/sec
	Difference: 13900 (604%)

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 largest amount of information (counted in megabytes per second) that can be transferred across the external memory interface within a second. The number is calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR type RAM, it should be multiplied by 2 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, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This number is worked out 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 video 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 amount of pixels the video card can possibly record to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
