GeForce 940M vs GeForce 9600 GSO 512MB

Intro

Compare all of that to the GeForce 9600 GSO 512MB, which uses a 65/55 nm design. nVidia has set the core frequency at 650 MHz. The GDDR3 RAM is set to run at a speed of 900 MHz on this specific model. It features 96 SPUs as well as 48 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce 9600 GSO 512MB should in theory be a lot faster than the GeForce 940M in general. (explain)

GeForce 9600 GSO 512MB		57600 MB/sec
GeForce 940M		16000 MB/sec
	Difference: 41600 (260%)

Texel Rate

The GeForce 9600 GSO 512MB will be a lot (more or less 21%) more effective at anisotropic filtering than the GeForce 940M. (explain)

GeForce 9600 GSO 512MB		31200 Mtexels/sec
GeForce 940M		25728 Mtexels/sec
	Difference: 5472 (21%)

Pixel Rate

The GeForce 9600 GSO 512MB will be a lot (approximately 21%) more effective at full screen anti-aliasing than the GeForce 940M, and also will be capable of handling higher screen resolutions without slowing down too much. (explain)

GeForce 9600 GSO 512MB		10400 Mpixels/sec
GeForce 940M		8576 Mpixels/sec
	Difference: 1824 (21%)

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 largest amount of data (measured in MB per second) that can be transported past the external memory interface within a second. It's calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

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