GeForce GTX 460 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 speed at 575 MHz. The DDR2 memory works at a speed of 500 MHz on this particular model. It features 80(16x5) SPUs as well as 8 Texture Address Units and 4 Rasterization Operator Units.

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

Performance-wise, the GeForce GTX 460 should in theory be quite a bit superior to the Radeon HD 4350 in general. (explain)

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

Texel Rate

The GeForce GTX 460 should be a lot (more or less 722%) better 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

The GeForce GTX 460 will be much (approximately 604%) more effective at anti-aliasing than the Radeon HD 4350, and should be capable of handling higher screen resolutions without losing too much performance. (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: Bandwidth is the maximum amount of information (in units of MB per second) that can be moved past the external memory interface in a 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 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster 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 are applied per second. This number is worked out by multiplying the total amount of texture units by the core 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 per second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
