Compare any two graphics cards:
Radeon HD 3870 1GB vs Radeon R5 M330
IntroThe Radeon HD 3870 1GB features a GPU core clock speed of 775 MHz, and the 1024 MB of GDDR4 RAM runs at 1125 MHz through a 256-bit bus. It also features 320(64x5) SPUs, 16 TAUs, and 16 Raster Operation Units.Compare that to the Radeon R5 M330, which has a GPU core clock speed of 1030 MHz, and 2048 MB of DDR3 RAM running at 900 MHz through a 64-bit bus. It also is made up of 320 Stream Processors, 20 Texture Address Units, and 8 ROPs.

Power Usage and Theoretical BenchmarksMemory BandwidthAs far as performance goes, the Radeon HD 3870 1GB should in theory be quite a bit superior to the Radeon R5 M330 overall. (explain)
Texel RateThe Radeon R5 M330 should be a lot (about 66%) faster with regards to texture filtering than the Radeon HD 3870 1GB. (explain)
Pixel RateThe Radeon HD 3870 1GB will be a lot (about 50%) faster with regards to FSAA than the Radeon R5 M330, and will be capable of handling higher resolutions better. (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 data (in units of MB per second) that can be transferred past the external memory interface in a second. It is worked out by multiplying the bus width by its memory clock speed. In the case of DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. 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 number of texture map elements (texels) that can be applied in one second. This number is worked out by multiplying the total texture units of the card by the core speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second. Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
