GeForce GTX 560 vs Radeon HD 4730

Intro

Compare those specs to the Radeon HD 4730, which has a core clock speed of 700 MHz and a GDDR5 memory speed of 900 MHz. It also makes use of a 128-bit bus, and makes use of a 55 nm design. It is comprised of 640(128x5) SPUs, 32 Texture Address Units, and 8 ROPs.

Memory Bandwidth

The GeForce GTX 560, in theory, should perform a lot faster than the Radeon HD 4730 in general. (explain)

GeForce GTX 560		128128 MB/sec
Radeon HD 4730		57600 MB/sec
	Difference: 70528 (122%)

Texel Rate

The GeForce GTX 560 will be quite a bit (more or less 103%) faster with regards to anisotropic filtering than the Radeon HD 4730. (explain)

GeForce GTX 560		45360 Mtexels/sec
Radeon HD 4730		22400 Mtexels/sec
	Difference: 22960 (103%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 560 is a better choice, by a large margin. (explain)

GeForce GTX 560		25920 Mpixels/sec
Radeon HD 4730		5600 Mpixels/sec
	Difference: 20320 (363%)

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 largest amount of information (in units of megabytes per second) that can be transported past the external memory interface within a second. It's worked out by multiplying the card's interface width by the speed of its memory. If the card has DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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