Compare any two graphics cards:
GeForce GTX 465 vs Radeon R9 M380
IntroThe GeForce GTX 465 features a core clock speed of 607 MHz and a GDDR5 memory speed of 802 MHz. It also features a 256-bit bus, and uses a 40 nm design. It is made up of 352 SPUs, 44 Texture Address Units, and 32 Raster Operation Units.Compare those specifications to the Radeon R9 M380, which uses a 28 nm design. AMD has clocked the core speed at 1000 MHz. The GDDR5 RAM works at a speed of 1500 MHz on this particular model. It features 640 SPUs along with 40 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksMemory BandwidthPerformance-wise, the GeForce GTX 465 should theoretically be a small bit better than the Radeon R9 M380 in general. (explain)
Texel RateThe Radeon R9 M380 is much (about 50%) more effective at AF than the GeForce GTX 465. (explain)
Pixel RateIf using a high resolution is important to you, then the GeForce GTX 465 is a better choice, and very much so. (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 maximum amount of information (in units of MB per second) that can be moved past the external memory interface in a second. The number is worked out by multiplying the interface width by the speed of its memory. If the card has DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total texture units of the card by the core speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second. Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
