GeForce 8500 GT vs GeForce 940M

Intro

Compare those specifications to the GeForce 940M, which features a GPU core clock speed of 1072 MHz, and 2048 MB of DDR3 RAM running at 1000 MHz through a 64-bit bus. It also is comprised of 384 Stream Processors, 24 Texture Address Units, and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the GeForce 940M should theoretically be quite a bit superior to 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 quite a bit (about 615%) faster with regards to AF 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 a high resolution is important to you, then the GeForce 940M is a better choice, by far. (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.

Price Comparison

Specifications

Memory Bandwidth: Bandwidth is the maximum amount of information (measured in MB per second) that can be moved across the external memory interface within a second. It is calculated by multiplying the bus width by its memory speed. If the card has DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
