Compare any two graphics cards:
GeForce GT 240 GDDR5 vs GeForce GTX 850M
IntroThe GeForce GT 240 GDDR5 uses a 40 nm design. nVidia has clocked the core frequency at 550 MHz. The GDDR5 RAM works at a speed of 850 MHz on this particular card. It features 96 SPUs as well as 32 TAUs and 8 Rasterization Operator Units.Compare that to the GeForce GTX 850M, which features clock speeds of 876 MHz on the GPU, and 1000 MHz on the 2048 MB of DDR3 RAM. It features 640 SPUs along with 40 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the GeForce GT 240 GDDR5 should be 70% faster than the GeForce GTX 850M in general, because of its greater data rate. (explain)
Texel RateThe GeForce GTX 850M should be much (more or less 99%) faster with regards to texture filtering than the GeForce GT 240 GDDR5. (explain)
Pixel RateThe GeForce GTX 850M is much (about 219%) better at full screen anti-aliasing than the GeForce GT 240 GDDR5, and also should be able to handle higher resolutions without losing too much performance. (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

Memory Bandwidth: Memory bandwidth is the largest amount of data (measured in MB per second) that can be moved over the external memory interface in one second. It is worked out by multiplying the bus width by the speed of its memory. In the case of DDR memory, it should be multiplied by 2 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 high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This number is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second. Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
