Compare any two graphics cards:
GeForce GTX 970M vs Radeon R9 390X 8G
IntroThe GeForce GTX 970M features core clock speeds of 924 MHz on the GPU, and 1000 MHz on the 3072 MB of GDDR5 memory. It features 1280 SPUs as well as 80 TAUs and 48 Rasterization Operator Units.Compare all of that to the Radeon R9 390X 8G, which makes use of a 28 nm design. AMD has set the core speed at 1050 MHz. The GDDR5 memory is set to run at a frequency of 1500 MHz on this particular model. It features 2816 SPUs along with 176 TAUs and 64 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon R9 390X 8G, in theory, should be much faster than the GeForce GTX 970M in general. (explain)
Texel RateThe Radeon R9 390X 8G will be a lot (approximately 150%) more effective at anisotropic filtering than the GeForce GTX 970M. (explain)
Pixel RateThe Radeon R9 390X 8G will be much (approximately 52%) faster with regards to full screen anti-aliasing than the GeForce GTX 970M, and should be capable of handling higher screen resolutions without losing too much performance. (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 (counted in MB per second) that can be transported past the external memory interface within a second. It's calculated by multiplying the card's bus width by its memory speed. If the card has DDR memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the 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 applied 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 this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second. Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly write to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the clock 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 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 potential to get to the maximum fill rate.
