Compare any two graphics cards:
Radeon HD 3850 256MB vs Radeon R9 M280X
IntroThe Radeon HD 3850 256MB features a GPU core clock speed of 668 MHz, and the 256 MB of GDDR3 RAM is set to run at 828 MHz through a 256-bit bus. It also features 320(64x5) Stream Processors, 16 TAUs, and 16 ROPs.Compare those specs to the Radeon R9 M280X, which has core speeds of 900 MHz on the GPU, and 1375 MHz on the 4096 MB of GDDR5 RAM. It features 896 SPUs along with 56 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksBoth cards have the same power consumption.Memory BandwidthThe Radeon R9 M280X, in theory, should perform much faster than the Radeon HD 3850 256MB overall. (explain)
Texel RateThe Radeon R9 M280X will be much (approximately 372%) better at AF than the Radeon HD 3850 256MB. (explain)
Pixel RateThe Radeon R9 M280X should be much (approximately 35%) more effective at AA than the Radeon HD 3850 256MB, and also should be able to handle higher resolutions without losing too much performance. (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 max amount of data (counted in MB per second) that can be transported past the external memory interface within a second. The number is calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This figure is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second. Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant 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.
