GeForce 9600 GSO 768MB vs GeForce GTX 750

Intro

Compare those specifications to the GeForce GTX 750, which features GPU clock speed of 1020 MHz, and 1024 MB of GDDR5 memory set to run at 1250 MHz through a 128-bit bus. It also is comprised of 512 Stream Processors, 32 TAUs, and 16 ROPs.

GeForce 9600 GSO 768MB		38400 MB/sec
	Difference: 41600 (108%)

Texel Rate

The GeForce GTX 750 will be quite a bit (more or less 24%) more effective at texture filtering than the GeForce 9600 GSO 768MB. (explain)

GeForce GTX 750		32640 Mtexels/sec
GeForce 9600 GSO 768MB		26400 Mtexels/sec
	Difference: 6240 (24%)

Pixel Rate

The GeForce GTX 750 is quite a bit (approximately 147%) faster with regards to anti-aliasing than the GeForce 9600 GSO 768MB, and also will be able to handle higher screen resolutions while still performing well. (explain)

GeForce GTX 750		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: Memory bandwidth is the max amount of data (in units of MB per second) that can be moved across the external memory interface in one second. It is calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This number is calculated 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 handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on many 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.
