GeForce GTX 750 Ti vs Radeon HD 5750 512MB

Intro

Compare all of that to the Radeon HD 5750 512MB, which makes use of a 40 nm design. AMD has clocked the core speed at 700 MHz. The GDDR5 memory runs at a frequency of 1150 MHz on this particular model. It features 720(144x5) SPUs as well as 36 TAUs and 16 Rasterization Operator Units.

	Difference: 12800 (17%)

Texel Rate

The GeForce GTX 750 Ti should be much (about 62%) better at AF than the Radeon HD 5750 512MB. (explain)

GeForce GTX 750 Ti		40800 Mtexels/sec
Radeon HD 5750 512MB		25200 Mtexels/sec
	Difference: 15600 (62%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 750 Ti is a better choice, by a large margin. (explain)

GeForce GTX 750 Ti		16320 Mpixels/sec
Radeon HD 5750 512MB		11200 Mpixels/sec
	Difference: 5120 (46%)

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 maximum amount of information (in units of MB per second) that can be transported across the external memory interface in one second. It is worked out by multiplying the card's interface width by the speed of its memory. In the case of DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
