GeForce 920M vs GeForce 9500 GT 1GB GDDR3

Intro

The GeForce 920M has a clock frequency of 954 MHz and a DDR3 memory speed of 900 MHz. It also uses a 64-bit bus, and uses a 28 nm design. It is comprised of 384 SPUs, 32 TAUs, and 8 ROPs.

Compare all that to the GeForce 9500 GT 1GB GDDR3, which uses a 55 nm design. nVidia has clocked the core speed at 550 MHz. The GDDR3 memory is set to run at a frequency of 800 MHz on this model. It features 32 SPUs as well as 16 TAUs and 8 ROPs.

GeForce 920M 30528 Mtexels/sec
GeForce 9500 GT 1GB GDDR3 8800 Mtexels/sec
Difference: 21728 (247%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce 920M is superior to the GeForce 9500 GT 1GB GDDR3, by a large margin. (explain)

GeForce 920M 7632 Mpixels/sec
GeForce 9500 GT 1GB GDDR3 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.

Memory Bandwidth: Bandwidth is the maximum amount of information (measured in megabytes per second) that can be moved over the external memory interface in one second. It's calculated by multiplying the card's bus width by the speed of its memory. In the case of DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the 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 texture map elements (texels) that can be applied in one second. This figure is worked out by multiplying the total texture units of the card by the core 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 in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
