Compare any two graphics cards:
Radeon HD 7950 3GB vs Radeon R9 M380
IntroThe Radeon HD 7950 3GB features a GPU core speed of 800 MHz, and the 3072 MB of GDDR5 RAM is set to run at 1250 MHz through a 384-bit bus. It also is made up of 1792 SPUs, 112 TAUs, and 32 ROPs.Compare all that to the Radeon R9 M380, which features a core clock frequency of 1000 MHz and a GDDR5 memory frequency of 1500 MHz. It also makes use of a 128-bit bus, and makes use of a 28 nm design. It is made up of 640 SPUs, 40 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical BenchmarksMemory BandwidthAs far as performance goes, the Radeon HD 7950 3GB should in theory be much better than the Radeon R9 M380 overall. (explain)
Texel RateThe Radeon HD 7950 3GB will be a lot (approximately 124%) better at AF than the Radeon R9 M380. (explain)
Pixel RateThe Radeon HD 7950 3GB is a lot (more or less 60%) faster with regards to FSAA than the Radeon R9 M380, and should be capable of handling higher screen 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 (measured in MB per second) that can be moved across the external memory interface within a second. It is worked out by multiplying the bus width by its memory speed. If the card has DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR 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 better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
