GeForce 9600 GSO 768MB vs GeForce GTX 965M

Intro

Compare all of that to the GeForce GTX 965M, which makes use of a 28 nm design. nVidia has set the core frequency at 944 MHz. The GDDR5 RAM is set to run at a speed of 1000 MHz on this particular model. It features 1024 SPUs as well as 64 Texture Address Units and 32 Rasterization Operator Units.

GeForce GTX 965M		60 Watts
GeForce 9600 GSO 768MB		84 Watts
	Difference: 24 Watts (40%)

Memory Bandwidth

The GeForce GTX 965M should in theory be quite a bit faster than the GeForce 9600 GSO 768MB in general. (explain)

GeForce GTX 965M		64000 MB/sec
GeForce 9600 GSO 768MB		38400 MB/sec
	Difference: 25600 (67%)

Texel Rate

The GeForce GTX 965M should be a lot (about 129%) faster with regards to anisotropic filtering than the GeForce 9600 GSO 768MB. (explain)

GeForce GTX 965M		60416 Mtexels/sec
GeForce 9600 GSO 768MB		26400 Mtexels/sec
	Difference: 34016 (129%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 965M is a better choice, by far. (explain)

GeForce GTX 965M		30208 Mpixels/sec
GeForce 9600 GSO 768MB		6600 Mpixels/sec
	Difference: 23608 (358%)

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 (in units of MB per second) that can be transported over the external memory interface in one second. The number is worked out by multiplying the interface width by its memory speed. If the card has DDR type RAM, the result should be multiplied by 2 once 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 anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This number is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

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