Compare any two graphics cards:
GeForce GT 240 GDDR5 vs GeForce GT 440 1.5GB
IntroThe GeForce GT 240 GDDR5 has a core clock frequency of 550 MHz and a GDDR5 memory speed of 850 MHz. It also makes use of a 128-bit memory bus, and uses a 40 nm design. It features 96 SPUs, 32 TAUs, and 8 ROPs.Compare those specifications to the GeForce GT 440 1.5GB, which features GPU core speed of 594 MHz, and 1536 MB of GDDR3 RAM running at 900 MHz through a 192-bit bus. It also is comprised of 144 Stream Processors, 24 TAUs, and 24 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the GeForce GT 240 GDDR5 should be 26% faster than the GeForce GT 440 1.5GB in general, because of its greater data rate. (explain)
Texel RateThe GeForce GT 240 GDDR5 should be quite a bit (approximately 23%) more effective at anisotropic filtering than the GeForce GT 440 1.5GB. (explain)
Pixel RateIf using a high resolution is important to you, then the GeForce GT 440 1.5GB is the winner, by far. (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 max amount of data (in units of megabytes per second) that can be transported across the external memory interface within a second. It's calculated by multiplying the card's bus width by its memory speed. If the card has DDR type memory, it should 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 anti-aliasing, HDR and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This number is worked out by multiplying the total texture units by the core clock speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second. Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
