GeForce GTX 550 Ti vs Radeon HD 5750 512MB

Intro

Compare all of that to the Radeon HD 5750 512MB, which comes with a core clock speed of 700 MHz and a GDDR5 memory frequency of 1150 MHz. It also uses a 128-bit bus, and uses a 40 nm design. It is made up of 720(144x5) SPUs, 36 TAUs, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 5750 512MB		86 Watts
GeForce GTX 550 Ti		116 Watts
	Difference: 30 Watts (35%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 550 Ti will be 34% faster than the Radeon HD 5750 512MB overall, because of its higher data rate. (explain)

GeForce GTX 550 Ti		98496 MB/sec
Radeon HD 5750 512MB		73600 MB/sec
	Difference: 24896 (34%)

Texel Rate

The GeForce GTX 550 Ti is just a bit (more or less 14%) faster with regards to texture filtering than the Radeon HD 5750 512MB. (explain)

GeForce GTX 550 Ti		28800 Mtexels/sec
Radeon HD 5750 512MB		25200 Mtexels/sec
	Difference: 3600 (14%)

Pixel Rate

The GeForce GTX 550 Ti will be quite a bit (more or less 93%) more effective at full screen anti-aliasing than the Radeon HD 5750 512MB, and also should be capable of handling higher screen resolutions more effectively. (explain)

GeForce GTX 550 Ti		21600 Mpixels/sec
Radeon HD 5750 512MB		11200 Mpixels/sec
	Difference: 10400 (93%)

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 information (measured in megabytes per second) that can be moved past the external memory interface in one second. It's calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better 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 processed in one second. This number is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. 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 lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
