GeForce 8500 GT vs GeForce 940M

Intro

Compare those specifications to the GeForce 940M, which comes with core clock speeds of 1072 MHz on the GPU, and 1000 MHz on the 2048 MB of DDR3 RAM. It features 384 SPUs along with 24 TAUs and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically, the GeForce 940M should be quite a bit faster than the GeForce 8500 GT in general. (explain)

GeForce 940M		16000 MB/sec
GeForce 8500 GT		12800 MB/sec
	Difference: 3200 (25%)

Texel Rate

The GeForce 940M is much (more or less 615%) better at anisotropic filtering than the GeForce 8500 GT. (explain)

GeForce 940M		25728 Mtexels/sec
GeForce 8500 GT		3600 Mtexels/sec
	Difference: 22128 (615%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce 940M is superior to the GeForce 8500 GT, and very much so. (explain)

GeForce 940M		8576 Mpixels/sec
GeForce 8500 GT		1800 Mpixels/sec
	Difference: 6776 (376%)

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 (measured in megabytes per second) that can be transferred over the external memory interface within a second. The number is worked out by multiplying the card's bus width by its memory speed. If it uses DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
