GeForce GTX 650 Ti vs Radeon HD 5750 512MB

Intro

Compare all that to the Radeon HD 5750 512MB, which has a clock speed of 700 MHz and a GDDR5 memory speed of 1150 MHz. It also features a 128-bit memory bus, and makes use of a 40 nm design. It is made up of 720(144x5) SPUs, 36 Texture Address Units, and 16 Raster Operation Units.

Radeon HD 5750 512MB		73600 MB/sec
	Difference: 12800 (17%)

Texel Rate

The GeForce GTX 650 Ti will be quite a bit (more or less 136%) faster with regards to texture filtering than the Radeon HD 5750 512MB. (explain)

GeForce GTX 650 Ti		59392 Mtexels/sec
Radeon HD 5750 512MB		25200 Mtexels/sec
	Difference: 34192 (136%)

Pixel Rate

The GeForce GTX 650 Ti is quite a bit (about 33%) better at AA than the Radeon HD 5750 512MB, and should be able to handle higher screen resolutions without slowing down too much. (explain)

GeForce GTX 650 Ti		14848 Mpixels/sec
Radeon HD 5750 512MB		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: Memory bandwidth is the max amount of data (measured in MB per second) that can be transported over the external memory interface in one second. The number is worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This figure is worked out by multiplying the total number of 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 number of pixels the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on quite a few 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.
