GeForce GTX 560 Ti vs Radeon HD 5670

Intro

Compare all of that to the Radeon HD 5670, which has a clock speed of 775 MHz and a GDDR5 memory frequency of 1000 MHz. It also uses a 128-bit memory bus, and makes use of a 40 nm design. It is made up of 400(80x5) SPUs, 20 Texture Address Units, and 8 ROPs.

Radeon HD 5670		61 Watts
GeForce GTX 560 Ti		170 Watts
	Difference: 109 Watts (179%)

Memory Bandwidth

The GeForce GTX 560 Ti should in theory be much faster than the Radeon HD 5670 in general. (explain)

GeForce GTX 560 Ti		128256 MB/sec
Radeon HD 5670		64000 MB/sec
	Difference: 64256 (100%)

Texel Rate

The GeForce GTX 560 Ti should be a lot (more or less 239%) better at texture filtering than the Radeon HD 5670. (explain)

GeForce GTX 560 Ti		52608 Mtexels/sec
Radeon HD 5670		15500 Mtexels/sec
	Difference: 37108 (239%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX 560 Ti is the winner, and very much so. (explain)

GeForce GTX 560 Ti		26304 Mpixels/sec
Radeon HD 5670		6200 Mpixels/sec
	Difference: 20104 (324%)

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 (in units of megabytes per second) that can be transported past the external memory interface in a second. The number is calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs 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 fill rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
