GeForce 9600 GSO 768MB vs GeForce GTX 970

Intro

Compare all of that to the GeForce GTX 970, which has 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 TAUs and 64 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 9600 GSO 768MB		84 Watts
GeForce GTX 970		145 Watts
	Difference: 61 Watts (73%)

Memory Bandwidth

In theory, the GeForce GTX 970 will be 483% quicker than the GeForce 9600 GSO 768MB overall, because of its higher bandwidth. (explain)

GeForce GTX 970		224000 MB/sec
GeForce 9600 GSO 768MB		38400 MB/sec
	Difference: 185600 (483%)

Texel Rate

The GeForce GTX 970 will be quite a bit (about 314%) more effective at texture 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 will be quite a bit (more or less 918%) faster with regards to AA than the GeForce 9600 GSO 768MB, and should be able to handle higher resolutions more effectively. (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 largest amount of data (counted in megabytes per second) that can be transported over the external memory interface within a second. It's worked out by multiplying the interface width by its memory clock speed. If the card has DDR type memory, it should be multiplied by 2 again. If 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 applied per second. This 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 video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
