GeForce GTX 550 Ti vs Radeon HD 5570

Intro

Compare those specs to the Radeon HD 5570, which comes with GPU clock speed of 650 MHz, and 512 MB of DDR3 RAM set to run at 900 MHz through a 128-bit bus. It also is made up of 400(80x5) Stream Processors, 20 TAUs, and 8 ROPs.

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

Memory Bandwidth

The GeForce GTX 550 Ti should in theory be much 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 is a lot (more or less 122%) more effective at texture filtering 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 running with high levels of AA is important to you, then the GeForce GTX 550 Ti is superior to the Radeon HD 5570, and very much so. (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 max amount of information (counted in MB per second) that can be transported across the external memory interface in a second. The number is calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This number is calculated by multiplying the total texture units of the card by the core speed of the chip. The better the texel rate, 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 could possibly write to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
