Compare any two graphics cards:
GeForce GT 440 1.5GB vs Radeon R9 M275X
IntroThe GeForce GT 440 1.5GB comes with clock speeds of 594 MHz on the GPU, and 900 MHz on the 1536 MB of GDDR3 RAM. It features 144 SPUs as well as 24 TAUs and 24 ROPs.Compare those specifications to the Radeon R9 M275X, which features GPU core speed of 900 MHz, and 2048 MB of GDDR5 RAM running at 1125 MHz through a 128-bit bus. It also is made up of 640 SPUs, 40 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon R9 M275X should theoretically perform a lot faster than the GeForce GT 440 1.5GB in general. (explain)
Texel RateThe Radeon R9 M275X is quite a bit (more or less 153%) more effective at texture filtering than the GeForce GT 440 1.5GB. (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the Radeon R9 M275X is a better choice, though only just barely. (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 transported past the external memory interface in one second. It's calculated by multiplying the 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 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
