GeForce 9600 GSO 768MB vs GeForce GTX 970

Intro

Compare those specifications to the GeForce GTX 970, which comes with core clock speeds of 1050 MHz on the GPU, and 1750 MHz on the 4096 MB of GDDR5 RAM. It features 1664 SPUs as well as 104 Texture Address Units and 64 Rasterization Operator Units.

GeForce 9600 GSO 768MB		38400 MB/sec
	Difference: 185600 (483%)

Texel Rate

The GeForce GTX 970 should be quite a bit (more or less 314%) better at anisotropic filtering than the GeForce 9600 GSO 768MB. (explain)

GeForce GTX 970		109200 Mtexels/sec
GeForce 9600 GSO 768MB		26400 Mtexels/sec
	Difference: 82800 (314%)

Pixel Rate

The GeForce GTX 970 is much (about 918%) more effective at AA than the GeForce 9600 GSO 768MB, and also capable of handling higher screen resolutions while still performing well. (explain)

GeForce GTX 970		67200 Mpixels/sec
GeForce 9600 GSO 768MB		6600 Mpixels/sec
	Difference: 60600 (918%)

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 (counted in megabytes per second) that can be transferred past the external memory interface in one second. It is calculated by multiplying the card's bus width by its memory clock speed. In the case of DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. 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 amount of texture map elements (texels) that can be processed per second. This number is calculated by multiplying the total texture units by the core clock speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
