GeForce 920M vs GeForce 9600 GT 512MB

Intro

The GeForce 920M features a GPU core speed of 954 MHz, and the 2048 MB of DDR3 memory is set to run at 900 MHz through a 64-bit bus. It also is made up of 384 SPUs, 32 TAUs, and 8 ROPs.

Compare all that to the GeForce 9600 GT 512MB, which makes use of a 65/55 nm design. nVidia has clocked the core speed at 650 MHz. The GDDR3 memory is set to run at a frequency of 900 MHz on this card. It features 64 SPUs along with 32 Texture Address Units and 16 ROPs.

GeForce 920M 14400 MB/sec
Difference: 43200 (300%)

Texel Rate

The GeForce 920M will be a lot (about 47%) more effective at anisotropic filtering than the GeForce 9600 GT 512MB. (explain)

GeForce 920M 30528 Mtexels/sec
GeForce 9600 GT 512MB 20800 Mtexels/sec
Difference: 9728 (47%)

Pixel Rate

The GeForce 9600 GT 512MB is quite a bit (about 36%) more effective at full screen anti-aliasing than the GeForce 920M, and will be capable of handling higher screen resolutions better. (explain)

GeForce 9600 GT 512MB 10400 Mpixels/sec
GeForce 920M 7632 Mpixels/sec
Difference: 2768 (36%)

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.

Memory Bandwidth: Memory bandwidth is the maximum amount of information (measured in megabytes per second) that can be transferred across the external memory interface within a second. It's calculated by multiplying the bus width by its memory clock speed. If the card has DDR RAM, it must be multiplied by 2 again. If it uses 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, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the video card could possibly write to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
