GeForce 920M vs GeForce 9600 GSO 384MB

Intro

Compare that to the GeForce 9600 GSO 384MB, which features a core clock frequency of 550 MHz and a GDDR3 memory speed of 800 MHz. It also uses a 192-bit bus, and makes use of a 65 nm design. It features 96 SPUs, 48 Texture Address Units, and 12 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the GeForce 9600 GSO 384MB should in theory be a lot superior to the GeForce 920M overall. (explain)

GeForce 9600 GSO 384MB		38400 MB/sec
GeForce 920M		14400 MB/sec
	Difference: 24000 (167%)

Texel Rate

The GeForce 920M should be just a bit (more or less 16%) more effective at AF than the GeForce 9600 GSO 384MB. (explain)

GeForce 920M		30528 Mtexels/sec
GeForce 9600 GSO 384MB		26400 Mtexels/sec
	Difference: 4128 (16%)

Pixel Rate

The GeForce 920M will be just a bit (approximately 16%) more effective at FSAA than the GeForce 9600 GSO 384MB, and should be capable of handling higher resolutions more effectively. (explain)

GeForce 920M		7632 Mpixels/sec
GeForce 9600 GSO 384MB		6600 Mpixels/sec
	Difference: 1032 (16%)

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 information (in units of megabytes per second) that can be transported over the external memory interface in one second. It is calculated by multiplying the bus width by its memory speed. In the case of DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This is worked out by multiplying the total number of texture units of the card by the core 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 in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
