GeForce 8500 GT vs GeForce 930M

Intro

Compare that to the GeForce 930M, which features a core clock frequency of 928 MHz and a DDR3 memory speed of 900 MHz. It also makes use of a 64-bit bus, and uses a 28 nm design. It is made up of 384 SPUs, 24 TAUs, and 8 Raster Operation Units.

GeForce 8500 GT		3600 Mtexels/sec
	Difference: 18672 (519%)

Pixel Rate

The GeForce 930M will be a lot (about 312%) faster with regards to AA than the GeForce 8500 GT, and also capable of handling higher screen resolutions more effectively. (explain)

GeForce 930M		7424 Mpixels/sec
GeForce 8500 GT		1800 Mpixels/sec
	Difference: 5624 (312%)

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 data (in units of megabytes per second) that can be transferred across the external memory interface in a second. The number is calculated by multiplying the interface width by its memory clock speed. If it uses DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, 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 texture map elements (texels) that are processed in one second. This is worked out by multiplying the total texture units by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
