Compare any two graphics cards:
Radeon HD 3870 X2 1GB vs Radeon R5 M230
IntroThe Radeon HD 3870 X2 1GB has clock speeds of 825 MHz on the GPU, and 1126 MHz on the 1024 MB of GDDR4 RAM. It features 320(64x5) SPUs as well as 16 TAUs and 16 Rasterization Operator Units.Compare those specs to the Radeon R5 M230, which features GPU clock speed of 780 MHz, and 2048 MB of DDR3 memory set to run at 1000 MHz through a 64-bit bus. It also is comprised of 320 Stream Processors, 20 TAUs, and 4 ROPs.

Power Usage and Theoretical BenchmarksMemory BandwidthIn theory, the Radeon HD 3870 X2 1GB should be 801% faster than the Radeon R5 M230 overall, due to its greater bandwidth. (explain)
Texel RateThe Radeon HD 3870 X2 1GB should be a lot (more or less 69%) faster with regards to AF than the Radeon R5 M230. (explain)
Pixel RateThe Radeon HD 3870 X2 1GB should be quite a bit (about 746%) better at full screen anti-aliasing than the Radeon R5 M230, and also will be able to handle higher resolutions more effectively. (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. One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of. Price Comparison

Display Specifications
Memory Bandwidth: Bandwidth is the maximum amount of data (counted in megabytes per second) that can be moved over the external memory interface in one second. It's calculated by multiplying the bus width by its memory speed. In the case of DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This is calculated by multiplying the total texture units of the card by the core speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
