GeForce GTX 460 1GB vs Radeon HD 4730

Intro

Compare all of that to the Radeon HD 4730, which uses a 55 nm design. AMD has set the core speed at 700 MHz. The GDDR5 memory is set to run at a speed of 900 MHz on this particular model. It features 640(128x5) SPUs as well as 32 TAUs and 8 Rasterization Operator Units.

	Difference: 57600 (100%)

Texel Rate

The GeForce GTX 460 1GB will be a lot (approximately 69%) better at AF than the Radeon HD 4730. (explain)

GeForce GTX 460 1GB		37800 Mtexels/sec
Radeon HD 4730		22400 Mtexels/sec
	Difference: 15400 (69%)

Pixel Rate

The GeForce GTX 460 1GB should be quite a bit (approximately 286%) more effective at AA than the Radeon HD 4730, and will be capable of handling higher screen resolutions more effectively. (explain)

GeForce GTX 460 1GB		21600 Mpixels/sec
Radeon HD 4730		5600 Mpixels/sec
	Difference: 16000 (286%)

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 data (in units of megabytes per second) that can be moved across the external memory interface in one second. The number is calculated by multiplying the interface width by its memory clock speed. If the card has DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The better the texel rate, the better the 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 number of pixels that the graphics chip could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the clock 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 also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
