Compare any two graphics cards:
Radeon R5 M330 vs Radeon R9 M380
IntroThe Radeon R5 M330 comes with a GPU core speed of 1030 MHz, and the 2048 MB of DDR3 memory runs at 900 MHz through a 64-bit bus. It also is made up of 320 Stream Processors, 20 Texture Address Units, and 8 Raster Operation Units.Compare that to the Radeon R9 M380, which makes use of a 28 nm design. AMD has clocked the core speed at 1000 MHz. The GDDR5 memory works at a speed of 1500 MHz on this particular card. It features 640 SPUs as well as 40 TAUs and 16 ROPs.

Power Usage and Theoretical BenchmarksMemory BandwidthThe Radeon R9 M380, in theory, should be much faster than the Radeon R5 M330 in general. (explain)
Texel RateThe Radeon R9 M380 is much (more or less 94%) faster with regards to AF than the Radeon R5 M330. (explain)
Pixel RateIf running with a high resolution is important to you, then the Radeon R9 M380 is superior to the Radeon R5 M330, by a large margin. (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 maximum amount of information (in units of megabytes per second) that can be transferred past the external memory interface within a second. It is worked out by multiplying the card's interface width by its memory speed. If it uses DDR RAM, it must be multiplied by 2 once again. If it uses 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 texture map elements (texels) that are processed in one second. This is calculated by multiplying the total texture units 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 a second. Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
