Compare any two graphics cards:
GeForce 8800 GTX vs Radeon R9 M380
IntroThe GeForce 8800 GTX comes with a clock speed of 575 MHz and a GDDR3 memory speed of 900 MHz. It also uses a 384-bit memory bus, and uses a 90 nm design. It features 128 SPUs, 64 Texture Address Units, and 24 Raster Operation Units.Compare those specs to the Radeon R9 M380, which has a core clock frequency of 1000 MHz and a GDDR5 memory speed of 1500 MHz. It also features a 128-bit bus, and uses a 28 nm design. It is made up of 640 SPUs, 40 TAUs, and 16 ROPs.
Display Graphs
Power Usage and Theoretical BenchmarksMemory BandwidthTheoretically speaking, the Radeon R9 M380 will be 11% quicker than the GeForce 8800 GTX in general, because of its greater bandwidth. (explain)
Texel RateThe Radeon R9 M380 will be a little bit (about 9%) more effective at anisotropic filtering than the GeForce 8800 GTX. (explain)
Pixel RateThe Radeon R9 M380 will be a bit (about 16%) faster with regards to full screen anti-aliasing than the GeForce 8800 GTX, and should be able to handle higher screen resolutions without losing too much performance. (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 megabytes per second) that can be transferred past the external memory interface within a second. It's worked out by multiplying the card's interface width by the speed of its memory. In the case of DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This number is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second. Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
