Compare any two graphics cards:
GeForce GT 220 GDDR3 vs Radeon R9 M395X
IntroThe GeForce GT 220 GDDR3 has a GPU core speed of 625 MHz, and the 512 MB of GDDR3 memory runs at 1012 MHz through a 128-bit bus. It also is made up of 48 Stream Processors, 16 Texture Address Units, and 8 Raster Operation Units.Compare that to the Radeon R9 M395X, which comes with GPU core speed of 723 MHz, and 4096 MB of GDDR5 RAM set to run at 1250 MHz through a 256-bit bus. It also is made up of 2048 SPUs, 128 Texture Address Units, and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the Radeon R9 M395X should theoretically be a lot better than the GeForce GT 220 GDDR3 in general. (explain)
Texel RateThe Radeon R9 M395X will be quite a bit (approximately 825%) faster with regards to anisotropic filtering than the GeForce GT 220 GDDR3. (explain)
Pixel RateThe Radeon R9 M395X will be quite a bit (approximately 363%) faster with regards to FSAA than the GeForce GT 220 GDDR3, and will be capable of handling higher screen resolutions without slowing down too much. (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 (measured in MB per second) that can be transferred across the external memory interface in one second. It is worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This figure is calculated 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 most pixels the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. 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 quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
