Compare any two graphics cards:
GeForce GTX 470 vs GeForce GTX 980M
IntroThe GeForce GTX 470 features a clock frequency of 607 MHz and a GDDR5 memory frequency of 837 MHz. It also features a 320-bit bus, and uses a 40 nm design. It features 448 SPUs, 56 Texture Address Units, and 40 Raster Operation Units.
Compare that to the GeForce GTX 980M, which features a core clock frequency of 1038 MHz and a GDDR5 memory frequency of 1000 MHz. It also makes use of a 256-bit bus, and makes use of a 28 nm design. It features 1536 SPUs, 96 Texture Address Units, and 64 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Performance-wise, the GeForce GTX 470 should theoretically be a little bit superior to the GeForce GTX 980M overall. (explain)
Texel RateThe GeForce GTX 980M will be much (approximately 193%) faster with regards to anisotropic filtering than the GeForce GTX 470. (explain)
Pixel RateThe GeForce GTX 980M should be a lot (more or less 174%) faster with regards to FSAA than the GeForce GTX 470, and should be capable of handling higher screen resolutions without slowing down too much. (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.
Please note that the price comparisons are based on search keywords - sometimes it might show cards with very similar names that are not exactly the same as the one chosen in the comparison. We do try to filter out the wrong results as best we can, though.
Memory Bandwidth: Memory bandwidth is the largest amount of information (counted in MB per second) that can be transferred past the external memory interface in a second. The number is calculated by multiplying the card's bus width by the speed of its memory. In the case of DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This number is worked out by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.
Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
