GeForce GTX 650 Ti 2GB vs Radeon HD 5750 1GB

Intro

Compare all of that to the Radeon HD 5750 1GB, which uses a 40 nm design. AMD has set the core speed at 700 MHz. The GDDR5 memory works at a frequency of 1150 MHz on this card. It features 720(144x5) SPUs along with 36 TAUs and 16 Rasterization Operator Units.

Texel Rate

The GeForce GTX 650 Ti 2GB will be quite a bit (approximately 136%) more effective at texture filtering than the Radeon HD 5750 1GB. (explain)

GeForce GTX 650 Ti 2GB		59392 Mtexels/sec
Radeon HD 5750 1GB		25200 Mtexels/sec
	Difference: 34192 (136%)

Pixel Rate

The GeForce GTX 650 Ti 2GB should be quite a bit (approximately 33%) more effective at anti-aliasing than the Radeon HD 5750 1GB, and should be able to handle higher resolutions while still performing well. (explain)

GeForce GTX 650 Ti 2GB		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 maximum amount of data (in units of MB per second) that can be transported over the external memory interface in a second. It is worked out by multiplying the bus width by its memory clock speed. In the case of DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly write to its local memory per 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 speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
