Compare any two graphics cards:
Radeon HD 4670 512MB vs Radeon R9 M380
IntroThe Radeon HD 4670 512MB makes use of a 55 nm design. AMD has set the core speed at 750 MHz. The GDDR4/GDDR3/DDR3/DDR2 memory runs at a frequency of 1000 MHz on this model. It features 320(64x5) SPUs along with 32 TAUs and 8 ROPs.Compare those specs to the Radeon R9 M380, which comes with a GPU core clock speed of 1000 MHz, and 4096 MB of GDDR5 RAM running at 1500 MHz through a 128-bit bus. It also is comprised of 640 SPUs, 40 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical BenchmarksMemory BandwidthThe Radeon R9 M380, in theory, should be quite a bit faster than the Radeon HD 4670 512MB overall. (explain)
Texel RateThe Radeon R9 M380 should be a lot (about 67%) better at AF than the Radeon HD 4670 512MB. (explain)
Pixel RateIf running with high levels of AA is important to you, then the Radeon R9 M380 is a better choice, and very much so. (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 data (counted in MB per second) that can be moved over the external memory interface within a second. The number is calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This number is calculated by multiplying the total number 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 processed in one second. Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out 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 drawing the pixels (image) on the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
