Compare any two graphics cards:
GeForce GTX 465 vs Radeon R9 M380
IntroThe GeForce GTX 465 has core speeds of 607 MHz on the GPU, and 802 MHz on the 1024 MB of GDDR5 RAM. It features 352 SPUs as well as 44 TAUs and 32 Rasterization Operator Units.Compare those specs to the Radeon R9 M380, which features core clock speeds of 1000 MHz on the GPU, and 1500 MHz on the 4096 MB of GDDR5 RAM. It features 640 SPUs along with 40 Texture Address Units and 16 ROPs.

Power Usage and Theoretical BenchmarksMemory BandwidthThe GeForce GTX 465, in theory, should be just a bit faster than the Radeon R9 M380 in general. (explain)
Texel RateThe Radeon R9 M380 is quite a bit (approximately 50%) faster with regards to texture filtering than the GeForce GTX 465. (explain)
Pixel RateThe GeForce GTX 465 is a lot (about 21%) more effective at AA than the Radeon R9 M380, 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: Memory bandwidth is the largest amount of information (measured in megabytes per second) that can be transferred past the external memory interface in one second. It's worked out by multiplying the interface width by the speed of its memory. If it uses DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This number is worked out by multiplying the total texture units 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 applied per second. Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
