GeForce GTX 480 vs Radeon HD 5670

Intro

Compare those specifications to the Radeon HD 5670, which makes use of a 40 nm design. AMD has set the core frequency at 775 MHz. The GDDR5 RAM runs at a frequency of 1000 MHz on this particular card. It features 400(80x5) SPUs along with 20 TAUs and 8 Rasterization Operator Units.

Radeon HD 5670		64000 MB/sec
	Difference: 113408 (177%)

Texel Rate

The GeForce GTX 480 should be quite a bit (approximately 171%) more effective at anisotropic filtering than the Radeon HD 5670. (explain)

GeForce GTX 480		42000 Mtexels/sec
Radeon HD 5670		15500 Mtexels/sec
	Difference: 26500 (171%)

Pixel Rate

The GeForce GTX 480 is quite a bit (more or less 442%) faster with regards to anti-aliasing than the Radeon HD 5670, and will be able to handle higher resolutions without slowing down too much. (explain)

GeForce GTX 480		33600 Mpixels/sec
Radeon HD 5670		6200 Mpixels/sec
	Difference: 27400 (442%)

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 (counted in MB per second) that can be transferred past the external memory interface in a second. The number is calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This figure is worked out by multiplying the total number of texture units by the core clock 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 applied per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
