Compare any two graphics cards:
Radeon HD 6570 (OEM) 2GB vs Radeon R9 285
IntroThe Radeon HD 6570 (OEM) 2GB comes with clock speeds of 650 MHz on the GPU, and 1000 MHz on the 1024 MB of GDDR5 RAM. It features 480 SPUs along with 24 TAUs and 8 Rasterization Operator Units.Compare all that to the Radeon R9 285, which makes use of a 28 nm design. AMD has clocked the core speed at 918 MHz. The GDDR5 RAM runs at a frequency of 1375 MHz on this particular model. It features 1792 SPUs along with 112 Texture Address Units and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon R9 285 should be 175% faster than the Radeon HD 6570 (OEM) 2GB overall, because of its higher data rate. (explain)
Texel RateThe Radeon R9 285 is a lot (approximately 559%) faster with regards to texture filtering than the Radeon HD 6570 (OEM) 2GB. (explain)
Pixel RateThe Radeon R9 285 is a lot (about 465%) faster with regards to FSAA than the Radeon HD 6570 (OEM) 2GB, and also should be capable of handling higher resolutions without slowing down too much. (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 max amount of data (counted in MB per second) that can be transported over the external memory interface in one second. It's worked out by multiplying the interface width by its memory clock speed. If the card has DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second. Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
