Compare any two graphics cards:
GeForce GT 340 vs Radeon R9 M295X
IntroThe GeForce GT 340 has a GPU clock speed of 550 MHz, and the 512 MB of GDDR5 memory is set to run at 850 MHz through a 128-bit bus. It also is comprised of 96 Stream Processors, 32 TAUs, and 8 ROPs.Compare all that to the Radeon R9 M295X, which features GPU core speed of 750 MHz, and 4096 MB of GDDR5 memory set to run at 1375 MHz through a 256-bit bus. It also features 2048 SPUs, 128 TAUs, and 32 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon R9 M295X should be a lot faster than the GeForce GT 340 overall. (explain)
Texel RateThe Radeon R9 M295X should be much (approximately 445%) better at AF than the GeForce GT 340. (explain)
Pixel RateThe Radeon R9 M295X should be much (about 445%) faster with regards to full screen anti-aliasing than the GeForce GT 340, and also will be able to handle higher resolutions while still performing well. (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 information (in units of megabytes per second) that can be transported over the external memory interface in one second. The number is worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This number is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second. Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
