Compare any two graphics cards:
GeForce GTX 460 2GB vs GeForce GTX 970M
IntroThe GeForce GTX 460 2GB uses a 40 nm design. nVidia has set the core frequency at 675 MHz. The GDDR5 RAM is set to run at a speed of 900 MHz on this particular card. It features 336 SPUs as well as 56 Texture Address Units and 32 Rasterization Operator Units.Compare all that to the GeForce GTX 970M, which has core speeds of 924 MHz on the GPU, and 1000 MHz on the 3072 MB of GDDR5 RAM. It features 1280 SPUs as well as 80 TAUs and 48 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the GeForce GTX 460 2GB is 20% faster than the GeForce GTX 970M in general, due to its higher bandwidth. (explain)
Texel RateThe GeForce GTX 970M should be a lot (approximately 96%) faster with regards to AF than the GeForce GTX 460 2GB. (explain)
Pixel RateIf using a high resolution is important to you, then the GeForce GTX 970M is the winner, 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 largest amount of data (in units of MB per second) that can be transported over the external memory interface within a second. The number is worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total texture units by the core speed of the chip. The higher this number, 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 most pixels that the graphics chip can possibly record to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
