Compare any two graphics cards:
GeForce GTX 275 vs GeForce GTX 970M
IntroThe GeForce GTX 275 makes use of a 55 nm design. nVidia has clocked the core speed at 633 MHz. The GDDR3 RAM works at a speed of 1134 MHz on this card. It features 240 SPUs as well as 80 TAUs and 28 Rasterization Operator Units.Compare those specs to the GeForce GTX 970M, which has a GPU core clock speed of 924 MHz, and 3072 MB of GDDR5 memory running at 1000 MHz through a 192-bit bus. It also is comprised of 1280 SPUs, 80 Texture Address Units, and 48 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce GTX 275, in theory, should be a lot faster than the GeForce GTX 970M overall. (explain)
Texel RateThe GeForce GTX 970M should be much (more or less 46%) better at AF than the GeForce GTX 275. (explain)
Pixel RateIf running with a high screen resolution is important to you, then the GeForce GTX 970M is superior to the GeForce GTX 275, by a large margin. (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: Bandwidth is the max amount of data (in units of MB per second) that can be moved across the external memory interface within a second. The number is calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, 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 processed in one second. This number is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel 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.
