Compare any two graphics cards:
GeForce 940M vs GeForce 9500 GT DDR2
IntroThe GeForce 940M has a clock speed of 1072 MHz and a DDR3 memory frequency of 1000 MHz. It also makes use of a 64-bit bus, and uses a 28 nm design. It is comprised of 384 SPUs, 24 Texture Address Units, and 8 Raster Operation Units.Compare those specifications to the GeForce 9500 GT DDR2, which has clock speeds of 550 MHz on the GPU, and 500 MHz on the 256 MB of DDR2 memory. It features 32 SPUs as well as 16 Texture Address Units and 8 ROPs.

Power Usage and Theoretical BenchmarksMemory BandwidthBoth cards have exactly the same bandwidth, so theoretically they should have identical performance. (explain)
Texel RateThe GeForce 940M will be a lot (approximately 192%) better at texture filtering than the GeForce 9500 GT DDR2. (explain)
Pixel RateThe GeForce 940M will be much (approximately 95%) more effective at AA than the GeForce 9500 GT DDR2, and also will be capable of handling higher resolutions without slowing down too much. (explain)
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

Display Specifications
Memory Bandwidth: Memory bandwidth is the maximum amount of information (in units of megabytes per second) that can be moved over 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 memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 amount of texture map elements (texels) that are applied in one second. This is worked out by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second. Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly write to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
