Compare any two graphics cards:
Geforce GTX 680 vs Radeon R9 M375X
IntroThe Geforce GTX 680 has a GPU core speed of 1006 MHz, and the 2048 MB of GDDR5 RAM runs at 1502 MHz through a 256-bit bus. It also is comprised of 1536 SPUs, 128 Texture Address Units, and 32 ROPs.Compare that to the Radeon R9 M375X, which makes use of a 28 nm design. AMD has clocked the core speed at 1015 MHz. The GDDR5 RAM is set to run at a speed of 1125 MHz on this specific card. It features 640 SPUs as well as 40 TAUs and 16 ROPs.
Display Graphs
Power Usage and Theoretical BenchmarksMemory BandwidthTheoretically speaking, the Geforce GTX 680 should be 167% faster than the Radeon R9 M375X in general, due to its greater data rate. (explain)
Texel RateThe Geforce GTX 680 will be a lot (approximately 217%) better at AF than the Radeon R9 M375X. (explain)
Pixel RateIf using high levels of AA is important to you, then the Geforce GTX 680 is superior to the Radeon R9 M375X, by far. (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 maximum amount of information (measured in megabytes per second) that can be moved over the external memory interface in a second. It is worked out by multiplying the card's interface width by its memory speed. If the card has DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel 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 get to the max fill rate.
