Compare any two graphics cards:
Radeon HD 5770 vs Radeon R9 M385X
IntroThe Radeon HD 5770 comes with a GPU clock speed of 850 MHz, and the 1024 MB of GDDR5 RAM runs at 1200 MHz through a 128-bit bus. It also features 800(160x5) SPUs, 40 Texture Address Units, and 16 ROPs.Compare those specifications to the Radeon R9 M385X, which has GPU core speed of 1100 MHz, and 4096 MB of GDDR5 RAM set to run at 1500 MHz through a 128-bit bus. It also features 896 SPUs, 56 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical BenchmarksMemory BandwidthThe Radeon R9 M385X should theoretically be quite a bit faster than the Radeon HD 5770 overall. (explain)
Texel RateThe Radeon R9 M385X should be a lot (approximately 81%) faster with regards to AF than the Radeon HD 5770. (explain)
Pixel RateThe Radeon R9 M385X should be a lot (more or less 29%) better at AA than the Radeon HD 5770, and also 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: Memory bandwidth is the largest amount of information (counted in MB per second) that can be transported across the external memory interface in one second. It is worked out by multiplying the bus width by the speed of its memory. If the card has DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This figure is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units 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 rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
