Compare any two graphics cards:
Radeon HD 6570 (OEM) 2GB vs Radeon R9 390X 8G
IntroThe Radeon HD 6570 (OEM) 2GB has a clock frequency of 650 MHz and a GDDR5 memory speed of 1000 MHz. It also makes use of a 128-bit bus, and makes use of a 40 nm design. It features 480 SPUs, 24 Texture Address Units, and 8 ROPs.Compare those specs to the Radeon R9 390X 8G, which features a GPU core clock speed of 1050 MHz, and 8192 MB of GDDR5 RAM set to run at 1500 MHz through a 512-bit bus. It also is comprised of 2816 SPUs, 176 Texture Address Units, and 64 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon R9 390X 8G will be 500% faster than the Radeon HD 6570 (OEM) 2GB in general, because of its higher bandwidth. (explain)
Texel RateThe Radeon R9 390X 8G should be much (about 1085%) faster with regards to texture filtering than the Radeon HD 6570 (OEM) 2GB. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the Radeon R9 390X 8G is superior to the Radeon HD 6570 (OEM) 2GB, 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: Bandwidth is the maximum amount of information (in units of MB per second) that can be transferred past the external memory interface in one second. It is calculated by multiplying the interface width by its memory speed. In the case of DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better 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 number of texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total amount of texture units by the core speed of the chip. The better this number, the better the graphics 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 maximum number of pixels that the graphics chip could possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the core 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 many 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.
