GeForce GTX 550 Ti vs Radeon HD 5570

Intro

Compare all of that to the Radeon HD 5570, which has GPU core speed of 650 MHz, and 512 MB of DDR3 memory set to run at 900 MHz through a 128-bit bus. It also is made up of 400(80x5) SPUs, 20 TAUs, and 8 Raster Operation Units.

Radeon HD 5570		43 Watts
GeForce GTX 550 Ti		116 Watts
	Difference: 73 Watts (170%)

Memory Bandwidth

The GeForce GTX 550 Ti should theoretically be quite a bit faster than the Radeon HD 5570 in general. (explain)

GeForce GTX 550 Ti		98496 MB/sec
Radeon HD 5570		28800 MB/sec
	Difference: 69696 (242%)

Texel Rate

The GeForce GTX 550 Ti will be a lot (more or less 122%) better at AF than the Radeon HD 5570. (explain)

GeForce GTX 550 Ti		28800 Mtexels/sec
Radeon HD 5570		13000 Mtexels/sec
	Difference: 15800 (122%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 550 Ti is a better choice, by far. (explain)

GeForce GTX 550 Ti		21600 Mpixels/sec
Radeon HD 5570		5200 Mpixels/sec
	Difference: 16400 (315%)

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 MB per second) that can be transferred past the external memory interface in one second. It's worked out by multiplying the card's bus width by its memory speed. If it uses DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
