Compare any two graphics cards:
GeForce 840M vs Radeon R9 M375
IntroThe GeForce 840M makes use of a 28 nm design. nVidia has clocked the core frequency at 1029 MHz. The DDR3 memory runs at a speed of 1000 MHz on this specific model. It features 384 SPUs along with 24 Texture Address Units and 8 Rasterization Operator Units.Compare those specifications to the Radeon R9 M375, which features core speeds of 1015 MHz on the GPU, and 1100 MHz on the 4096 MB of DDR3 memory. It features 640 SPUs as well as 40 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksMemory BandwidthIn theory, the Radeon R9 M375 will be 120% faster than the GeForce 840M overall, due to its greater data rate. (explain)
Texel RateThe Radeon R9 M375 should be quite a bit (approximately 64%) more effective at AF than the GeForce 840M. (explain)
Pixel RateThe Radeon R9 M375 should be a lot (approximately 97%) faster with regards to full screen anti-aliasing than the GeForce 840M, and should be capable of handling higher screen resolutions better. (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 information (in units of MB per second) that can be transported over the external memory interface in one second. The number is calculated by multiplying the card's interface width by its memory speed. If it uses DDR RAM, it should 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 AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher the texel rate, 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 amount of pixels the video card can possibly write to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
