Compare any two graphics cards:
GeForce GTX 970 vs GeForce GTX 980M
IntroThe GeForce GTX 970 comes with a clock speed of 1050 MHz and a GDDR5 memory speed of 1750 MHz. It also makes use of a 256-bit memory bus, and uses a 28 nm design. It is comprised of 1664 SPUs, 104 Texture Address Units, and 64 ROPs.
Compare those specs to the GeForce GTX 980M, which uses a 28 nm design. nVidia has set the core speed at 1038 MHz. The GDDR5 RAM works at a speed of 1000 MHz on this particular model. It features 1536 SPUs as well as 96 TAUs and 64 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
In theory, the GeForce GTX 970 should be 75% quicker than the GeForce GTX 980M overall, due to its greater bandwidth. (explain)
Texel RateThe GeForce GTX 970 will be just a bit (approximately 10%) more effective at anisotropic filtering than the GeForce GTX 980M. (explain)
Pixel RateThe GeForce GTX 970 will be a bit (approximately 1%) better at full screen anti-aliasing than the GeForce GTX 980M, and will be able to handle higher 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 maximum amount of information (in units of MB per second) that can be transferred past the external memory interface within a second. It's calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This figure is worked out by multiplying the total texture units by the core clock 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 most pixels the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
