Compare any two graphics cards:
GeForce GT 440 3GB vs GeForce GTS 150
IntroThe GeForce GT 440 3GB comes with a core clock frequency of 594 MHz and a GDDR3 memory frequency of 900 MHz. It also features a 192-bit memory bus, and makes use of a 40 nm design. It features 144 SPUs, 24 Texture Address Units, and 24 Raster Operation Units.Compare all that to the GeForce GTS 150, which features a GPU core clock speed of 740 MHz, and 1024 MB of GDDR3 memory set to run at 500 MHz through a 256-bit bus. It also is comprised of 128 Stream Processors, 64 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the GeForce GT 440 3GB will be 35% faster than the GeForce GTS 150 in general, because of its greater data rate. (explain)
Texel RateThe GeForce GTS 150 should be quite a bit (more or less 232%) better at AF than the GeForce GT 440 3GB. (explain)
Pixel RateIf using a high resolution is important to you, then the GeForce GT 440 3GB is superior to the GeForce GTS 150, not by a very large margin though. (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 data (measured in megabytes per second) that can be moved past the external memory interface within a second. The number is worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This figure is calculated by multiplying the total number of texture units by the core speed of the chip. The higher this number, the better the video 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 the video card can possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the clock speed of the card. 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 ability to get to the max fill rate.
