Compare any two graphics cards:
GeForce GT 240 GDDR5 1GB vs GeForce GTX 980
IntroThe GeForce GT 240 GDDR5 1GB uses a 40 nm design. nVidia has set the core speed at 550 MHz. The GDDR5 memory runs at a speed of 850 MHz on this specific card. It features 96 SPUs along with 32 TAUs and 8 Rasterization Operator Units.Compare those specifications to the GeForce GTX 980, which features a core clock speed of 1126 MHz and a GDDR5 memory speed of 1750 MHz. It also features a 256-bit bus, and uses a 28 nm design. It is comprised of 2048 SPUs, 128 TAUs, and 64 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce GTX 980, in theory, should be quite a bit faster than the GeForce GT 240 GDDR5 1GB in general. (explain)
Texel RateThe GeForce GTX 980 should be much (approximately 719%) faster with regards to texture filtering than the GeForce GT 240 GDDR5 1GB. (explain)
Pixel RateThe GeForce GTX 980 will be a lot (approximately 1538%) faster with regards to AA than the GeForce GT 240 GDDR5 1GB, and capable of handling higher screen 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 (counted in megabytes per second) that can be moved past the external memory interface within a second. It is worked out by multiplying the bus width by the speed of its memory. If the card has DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's 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 amount of texture map elements (texels) that are applied in one second. This figure is calculated by multiplying the total texture units by the core speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second. Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
