GeForce 920M vs GeForce 9600 GSO 768MB

Intro

Compare all that to the GeForce 9600 GSO 768MB, which makes use of a 65 nm design. nVidia has clocked the core frequency at 550 MHz. The GDDR3 RAM is set to run at a speed of 800 MHz on this specific card. It features 96 SPUs as well as 48 Texture Address Units and 12 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce 9600 GSO 768MB will be 167% faster than the GeForce 920M overall, due to its greater data rate. (explain)

GeForce 9600 GSO 768MB		38400 MB/sec
GeForce 920M		14400 MB/sec
	Difference: 24000 (167%)

Texel Rate

The GeForce 920M is a little bit (more or less 16%) faster with regards to anisotropic filtering than the GeForce 9600 GSO 768MB. (explain)

GeForce 920M		30528 Mtexels/sec
GeForce 9600 GSO 768MB		26400 Mtexels/sec
	Difference: 4128 (16%)

Pixel Rate

The GeForce 920M should be just a bit (about 16%) better at AA than the GeForce 9600 GSO 768MB, and should be capable of handling higher screen resolutions without losing too much performance. (explain)

GeForce 920M		7632 Mpixels/sec
GeForce 9600 GSO 768MB		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 maximum amount of data (in units of megabytes per second) that can be transported past the external memory interface within a second. The number is worked out by multiplying the bus width by its memory speed. If it uses DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units 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 many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
