GeForce 9600 GT 512MB vs GeForce GTX 750 Ti

Intro

Compare those specifications to the GeForce GTX 750 Ti, which makes use of a 28 nm design. nVidia has clocked the core frequency at 1020 MHz. The GDDR5 RAM works at a frequency of 1350 MHz on this model. It features 640 SPUs as well as 40 Texture Address Units and 16 ROPs.

GeForce GTX 750 Ti		60 Watts
GeForce 9600 GT 512MB		95 Watts
	Difference: 35 Watts (58%)

Memory Bandwidth

Theoretically, the GeForce GTX 750 Ti should perform quite a bit faster than the GeForce 9600 GT 512MB overall. (explain)

GeForce GTX 750 Ti		86400 MB/sec
GeForce 9600 GT 512MB		57600 MB/sec
	Difference: 28800 (50%)

Texel Rate

The GeForce GTX 750 Ti should be a lot (more or less 96%) more effective at AF than the GeForce 9600 GT 512MB. (explain)

GeForce GTX 750 Ti		40800 Mtexels/sec
GeForce 9600 GT 512MB		20800 Mtexels/sec
	Difference: 20000 (96%)

Pixel Rate

The GeForce GTX 750 Ti should be quite a bit (approximately 57%) better at AA than the GeForce 9600 GT 512MB, and also capable of handling higher resolutions better. (explain)

GeForce GTX 750 Ti		16320 Mpixels/sec
GeForce 9600 GT 512MB		10400 Mpixels/sec
	Difference: 5920 (57%)

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 max amount of information (counted in MB per second) that can be transferred across the external memory interface in a second. It is worked out by multiplying the interface width by the speed of its memory. If the card has DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
