Compare any two graphics cards:
Radeon HD 6790 vs Radeon RX 460 2GB
IntroThe Radeon HD 6790 has a GPU core speed of 840 MHz, and the 1024 MB of GDDR5 RAM runs at 1050 MHz through a 256-bit bus. It also is comprised of 800 Stream Processors, 40 TAUs, and 16 Raster Operation Units.Compare all that to the Radeon RX 460 2GB, which features a core clock speed of 1090 MHz and a GDDR5 memory frequency of 1750 MHz. It also features a 128-bit memory bus, and makes use of a 14 nm design. It is made up of 896 SPUs, 56 TAUs, and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon HD 6790 is 20% quicker than the Radeon RX 460 2GB in general, due to its greater data rate. (explain)
Texel RateThe Radeon RX 460 2GB should be quite a bit (more or less 82%) more effective at anisotropic filtering than the Radeon HD 6790. (explain)
Pixel RateThe Radeon RX 460 2GB will be much (approximately 30%) faster with regards to AA than the Radeon HD 6790, and able to handle higher screen resolutions more effectively. (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 (counted in MB per second) that can be transferred across the external memory interface in one second. It's worked out by multiplying the card's interface width by its memory speed. If it uses DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This figure is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the core clock speed. 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 rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
