Compare any two graphics cards:
GeForce GTX 560 Ti 448 vs GeForce GTX 980M
IntroThe GeForce GTX 560 Ti 448 comes with a clock frequency of 732 MHz and a GDDR5 memory speed of 900 MHz. It also makes use of a 320-bit memory bus, and makes use of a 40 nm design. It is comprised of 448 SPUs, 56 TAUs, and 40 Raster Operation Units.
Compare those specifications to the GeForce GTX 980M, which comes with core clock speeds of 1038 MHz on the GPU, and 1000 MHz on the 4096 MB of GDDR5 memory. It features 1536 SPUs as well as 96 Texture Address Units and 64 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically, the GeForce GTX 560 Ti 448 should be a bit faster than the GeForce GTX 980M overall. (explain)
Texel RateThe GeForce GTX 980M should be a lot (more or less 143%) better at texture filtering than the GeForce GTX 560 Ti 448. (explain)
Pixel RateThe GeForce GTX 980M will be quite a bit (approximately 127%) faster with regards to anti-aliasing than the GeForce GTX 560 Ti 448, and will be able to handle higher resolutions while still performing well. (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 data (measured in megabytes per second) that can be transported past the external memory interface in a second. It is worked out by multiplying the interface width by its memory speed. If the card has DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better 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 are applied in one second. This figure is worked out by multiplying the total amount of texture units by the core clock 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 processed per second.
Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - aka 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 of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
