GeForce 920M vs GeForce 9500 GT DDR2

Intro

Compare those specs to the GeForce 9500 GT DDR2, which has a core clock speed of 550 MHz and a DDR2 memory frequency of 500 MHz. It also uses a 128-bit memory bus, and uses a 65 nm design. It features 32 SPUs, 16 TAUs, and 8 ROPs.

GeForce 9500 GT DDR2		8800 Mtexels/sec
	Difference: 21728 (247%)

Pixel Rate

The GeForce 920M will be a lot (about 73%) faster with regards to full screen anti-aliasing than the GeForce 9500 GT DDR2, and also able to handle higher screen resolutions better. (explain)

GeForce 920M		7632 Mpixels/sec
GeForce 9500 GT DDR2		4400 Mpixels/sec
	Difference: 3232 (73%)

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 information (counted in megabytes per second) that can be moved past the external memory interface in one second. The number is worked out by multiplying the interface width by the speed of its memory. If it uses DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster 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 number of texture map elements (texels) that can be applied in one second. This figure 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 card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour 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 rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
