Compare any two graphics cards:
GeForce 810M vs GeForce 9400 GT 256MB
IntroThe GeForce 810M comes with clock speeds of 738 MHz on the GPU, and 900 MHz on the 1024 MB of DDR3 memory. It features 48 SPUs along with 8 Texture Address Units and 4 Rasterization Operator Units.Compare those specs to the GeForce 9400 GT 256MB, which features a clock speed of 550 MHz and a GDDR2 memory frequency of 400 MHz. It also features a 128-bit memory bus, and uses a 65 nm design. It is comprised of 16 SPUs, 8 Texture Address Units, and 4 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the GeForce 810M will be 13% faster than the GeForce 9400 GT 256MB overall, because of its higher data rate. (explain)
Texel RateThe GeForce 810M is much (more or less 34%) better at anisotropic filtering than the GeForce 9400 GT 256MB. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the GeForce 810M is a better choice, and very much so. (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 max amount of information (in units of megabytes per second) that can be transferred past the external memory interface in a second. It's calculated by multiplying the card's interface width by its memory speed. If the card has DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second. Pixel Rate: Pixel rate is the most pixels the video card could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the the core clock speed. 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 also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
