GeForce 9600 GSO 768MB vs GeForce GTX 750 Ti

Intro

Compare all that to the GeForce GTX 750 Ti, which comes with GPU core speed of 1020 MHz, and 2048 MB of GDDR5 memory set to run at 1350 MHz through a 128-bit bus. It also features 640 SPUs, 40 TAUs, and 16 ROPs.

Pixel Rate

If using a high screen resolution is important to you, then the GeForce GTX 750 Ti is a better choice, by far. (explain)

GeForce GTX 750 Ti		16320 Mpixels/sec
GeForce 9600 GSO 768MB		6600 Mpixels/sec
	Difference: 9720 (147%)

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 largest amount of data (measured in MB per second) that can be transferred past the external memory interface within a second. The number is calculated by multiplying the card's bus width by its memory speed. In the case of DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's 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 texture map elements (texels) that are processed in one second. This number is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also called 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, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
