GeForce GTX 650 Ti vs Radeon HD 5750 1GB

Intro

Compare that to the Radeon HD 5750 1GB, which has core clock speeds of 700 MHz on the GPU, and 1150 MHz on the 1024 MB of GDDR5 memory. It features 720(144x5) SPUs as well as 36 TAUs and 16 Rasterization Operator Units.

Radeon HD 5750 1GB		86 Watts
GeForce GTX 650 Ti		110 Watts
	Difference: 24 Watts (28%)

Memory Bandwidth

Theoretically, the GeForce GTX 650 Ti should perform a little bit faster than the Radeon HD 5750 1GB in general. (explain)

GeForce GTX 650 Ti		86400 MB/sec
Radeon HD 5750 1GB		73600 MB/sec
	Difference: 12800 (17%)

Texel Rate

The GeForce GTX 650 Ti should be quite a bit (more or less 136%) more effective at anisotropic filtering than the Radeon HD 5750 1GB. (explain)

GeForce GTX 650 Ti		59392 Mtexels/sec
Radeon HD 5750 1GB		25200 Mtexels/sec
	Difference: 34192 (136%)

Pixel Rate

If using a high resolution is important to you, then the GeForce GTX 650 Ti is a better choice, by far. (explain)

GeForce GTX 650 Ti		14848 Mpixels/sec
Radeon HD 5750 1GB		11200 Mpixels/sec
	Difference: 3648 (33%)

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 data (counted in megabytes per second) that can be transferred across the external memory interface in one second. It is worked out by multiplying the card's interface width by its memory speed. If the card has DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the video card can possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
