Compare any two graphics cards:
GeForce GTX 285 2GB vs Radeon R9 M395X
IntroThe GeForce GTX 285 2GB has a core clock speed of 648 MHz and a GDDR3 memory frequency of 1242 MHz. It also uses a 512-bit bus, and makes use of a 55 nm design. It features 240 SPUs, 80 Texture Address Units, and 32 Raster Operation Units.Compare those specs to the Radeon R9 M395X, which uses a 28 nm design. AMD has set the core speed at 723 MHz. The GDDR5 RAM runs at a frequency of 1250 MHz on this particular card. It features 2048 SPUs as well as 128 TAUs and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the Radeon R9 M395X should perform just a bit faster than the GeForce GTX 285 2GB overall. (explain)
Texel RateThe Radeon R9 M395X will be a lot (approximately 79%) more effective at anisotropic filtering than the GeForce GTX 285 2GB. (explain)
Pixel RateIf using a high screen resolution is important to you, then the Radeon R9 M395X is a better choice, not by a very large margin though. (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 (counted in megabytes per second) that can be moved across the external memory interface in a second. The number is worked out by multiplying the card's interface width by its memory speed. If the card has DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's 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 are applied in one second. This figure is worked out by multiplying the total texture units of the card by the core speed of the chip. The higher the texel rate, the better the 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 most pixels that the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
