Compare any two graphics cards:
Radeon HD 4730 vs Radeon R9 M280X
IntroThe Radeon HD 4730 has a GPU core speed of 700 MHz, and the 512 MB of GDDR5 RAM is set to run at 900 MHz through a 128-bit bus. It also features 640(128x5) Stream Processors, 32 TAUs, and 8 Raster Operation Units.Compare that to the Radeon R9 M280X, which makes use of a 28 nm design. AMD has clocked the core speed at 900 MHz. The GDDR5 memory runs at a frequency of 1375 MHz on this card. It features 896 SPUs as well as 56 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon R9 M280X should be much faster than the Radeon HD 4730 overall. (explain)
Texel RateThe Radeon R9 M280X should be quite a bit (approximately 125%) faster with regards to anisotropic filtering than the Radeon HD 4730. (explain)
Pixel RateThe Radeon R9 M280X will be a lot (more or less 157%) better at FSAA than the Radeon HD 4730, and should be capable of handling higher screen 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 largest amount of information (counted in MB per second) that can be moved past the external memory interface within a second. The number is worked out by multiplying the bus width by the speed of its memory. If it uses DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum number 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 clock speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs 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 fill rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
