GeForce GTX 470 vs Radeon HD 4350

Intro

Compare all of that to the Radeon HD 4350, which has a clock speed of 575 MHz and a DDR2 memory frequency of 500 MHz. It also makes use of a 64-bit bus, and makes use of a 55 nm design. It features 80(16x5) SPUs, 8 Texture Address Units, and 4 Raster Operation Units.

Radeon HD 4350		4600 Mtexels/sec
	Difference: 29392 (639%)

Pixel Rate

The GeForce GTX 470 will be a lot (approximately 956%) faster with regards to AA than the Radeon HD 4350, and should be capable of handling higher screen resolutions better. (explain)

GeForce GTX 470		24280 Mpixels/sec
Radeon HD 4350		2300 Mpixels/sec
	Difference: 21980 (956%)

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 data (measured in MB per second) that can be transferred over the external memory interface within a second. It is worked out by multiplying the card's interface width by the speed of its memory. If the card has DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This is calculated by multiplying the total number of texture units by the core speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
