GeForce GTX 750 Ti vs Radeon HD 5750 1GB

Intro

Compare that to the Radeon HD 5750 1GB, which comes with GPU core speed of 700 MHz, and 1024 MB of GDDR5 memory set to run at 1150 MHz through a 128-bit bus. It also features 720(144x5) SPUs, 36 TAUs, and 16 ROPs.

GeForce GTX 750 Ti		60 Watts
Radeon HD 5750 1GB		86 Watts
	Difference: 26 Watts (43%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 750 Ti should be 17% faster than the Radeon HD 5750 1GB overall, because of its higher bandwidth. (explain)

GeForce GTX 750 Ti		86400 MB/sec
Radeon HD 5750 1GB		73600 MB/sec
	Difference: 12800 (17%)

Texel Rate

The GeForce GTX 750 Ti will be much (more or less 62%) better at texture filtering than the Radeon HD 5750 1GB. (explain)

GeForce GTX 750 Ti		40800 Mtexels/sec
Radeon HD 5750 1GB		25200 Mtexels/sec
	Difference: 15600 (62%)

Pixel Rate

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

GeForce GTX 750 Ti		16320 Mpixels/sec
Radeon HD 5750 1GB		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: Memory bandwidth is the max amount of information (in units of megabytes per second) that can be moved across the external memory interface within a second. It is worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the better 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 texture map elements (texels) that are applied per second. This is worked out by multiplying the total texture units of the card by the core speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the the core 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 output rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
