Compare any two graphics cards:
GeForce GTS 250 512MB vs GeForce GTX 965M
IntroThe GeForce GTS 250 512MB comes with a core clock frequency of 738 MHz and a GDDR3 memory frequency of 1100 MHz. It also features a 256-bit bus, and uses a 65/55 nm design. It is made up of 128 SPUs, 64 Texture Address Units, and 16 ROPs.Compare those specifications to the GeForce GTX 965M, which uses a 28 nm design. nVidia has set the core frequency at 944 MHz. The GDDR5 memory works at a frequency of 1000 MHz on this particular model. It features 1024 SPUs as well as 64 Texture Address Units and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the GeForce GTS 250 512MB should in theory be a bit superior to the GeForce GTX 965M in general. (explain)
Texel RateThe GeForce GTX 965M will be quite a bit (more or less 28%) more effective at anisotropic filtering than the GeForce GTS 250 512MB. (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the GeForce GTX 965M 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 (measured in megabytes per second) that can be transported past the external memory interface within a second. It's worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This number is calculated by multiplying the total number of texture units by the core speed of the chip. The better the texel rate, the better the graphics 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 a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
