Compare any two graphics cards:
GeForce GT 315 vs Radeon R9 M380
IntroThe GeForce GT 315 comes with a GPU core speed of 625 MHz, and the 512 MB of DDR3 RAM runs at 790 MHz through a 128-bit bus. It also is comprised of 48 Stream Processors, 16 Texture Address Units, and 8 Raster Operation Units.Compare those specifications to the Radeon R9 M380, which features a core clock frequency of 1000 MHz and a GDDR5 memory frequency of 1500 MHz. It also makes use of a 128-bit bus, and uses a 28 nm design. It is made up of 640 SPUs, 40 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical BenchmarksMemory BandwidthAs far as performance goes, the Radeon R9 M380 should in theory be much better than the GeForce GT 315 overall. (explain)
Texel RateThe Radeon R9 M380 should be much (about 300%) more effective at AF than the GeForce GT 315. (explain)
Pixel RateIf running with a high screen resolution is important to you, then the Radeon R9 M380 is a better choice, 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: Memory bandwidth is the largest amount of data (in units of megabytes per second) that can be transported over the external memory interface within a second. It is calculated by multiplying the interface width by its memory speed. If the card has DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second. Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
