Compare any two graphics cards:
Geforce GTX 670 vs Radeon R9 M395X
IntroThe Geforce GTX 670 makes use of a 28 nm design. nVidia has set the core frequency at 915 MHz. The GDDR5 memory runs at a frequency of 1500 MHz on this particular card. It features 1344 SPUs as well as 112 TAUs and 32 Rasterization Operator Units.Compare those specifications to the Radeon R9 M395X, which makes use of a 28 nm design. AMD has set the core frequency at 723 MHz. The GDDR5 memory is set to run at a frequency of 1250 MHz on this particular card. It features 2048 SPUs as well as 128 Texture Address Units and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the Geforce GTX 670 is 20% faster than the Radeon R9 M395X in general, because of its greater bandwidth. (explain)
Texel RateThe Geforce GTX 670 should be just a bit (more or less 11%) more effective at AF than the Radeon R9 M395X. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the Geforce GTX 670 is a better choice, and very much so. (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 maximum amount of information (in units of megabytes per second) that can be transported over the external memory interface within a second. It's calculated by multiplying the interface width by the speed of its memory. If it uses DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum 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 clock speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs 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 fill rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
