GeForce 9600 GSO 768MB vs GeForce GTX 750

Intro

Compare all that to the GeForce GTX 750, which makes use of a 28 nm design. nVidia has clocked the core speed at 1020 MHz. The GDDR5 memory works at a speed of 1250 MHz on this particular model. It features 512 SPUs as well as 32 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 750		55 Watts
GeForce 9600 GSO 768MB		84 Watts
	Difference: 29 Watts (53%)

Memory Bandwidth

In theory, the GeForce GTX 750 will be 108% faster than the GeForce 9600 GSO 768MB in general, because of its higher bandwidth. (explain)

GeForce GTX 750		80000 MB/sec
GeForce 9600 GSO 768MB		38400 MB/sec
	Difference: 41600 (108%)

Texel Rate

The GeForce GTX 750 is much (about 24%) more effective at AF 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 a lot (approximately 147%) better at full screen anti-aliasing than the GeForce 9600 GSO 768MB, and also will be capable of handling higher resolutions better. (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 maximum amount of data (counted in megabytes per second) that can be moved past 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 type memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This is worked out by multiplying the total texture units of the card by the core speed of the chip. The better this number, the better the graphics card will be at 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 the video card can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated 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 filling the screen with pixels (the image). The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
