GeForce 940M vs GeForce 9600 GSO 512MB

Intro

Compare all that to the GeForce 9600 GSO 512MB, which has a clock frequency of 650 MHz and a GDDR3 memory frequency of 900 MHz. It also makes use of a 256-bit memory bus, and makes use of a 65/55 nm design. It is made up of 96 SPUs, 48 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce 9600 GSO 512MB will be 260% faster than the GeForce 940M in general, because of its higher data rate. (explain)

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

Texel Rate

The GeForce 9600 GSO 512MB should be much (approximately 21%) faster with regards to 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 is much (about 21%) better at full screen anti-aliasing than the GeForce 940M, and also will be able to handle higher resolutions better. (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: Memory bandwidth is the largest amount of information (measured in MB per second) that can be moved past the external memory interface within a second. The number is worked out by multiplying the bus width by its memory clock speed. In the case of DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, 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 number of texture map elements (texels) that are applied in one second. This is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

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