GeForce GT 240 GDDR5 vs GeForce GT 240 GDDR5 1GB
Intro
The GeForce GT 240 GDDR5 makes use of a 40 nm design. nVidia has set the core speed at 550 MHz. The GDDR5 memory runs at a frequency of 850 MHz on this model. It features 96 SPUs along with 32 Texture Address Units and 8 ROPs.Compare that to the GeForce GT 240 GDDR5 1GB, which makes use of a 40 nm design. nVidia has set the core speed at 550 MHz. The GDDR5 RAM works at a speed of 850 MHz on this specific card. It features 96 SPUs along with 32 TAUs and 8 Rasterization Operator Units.
Power Usage and Theoretical Benchmarks
Both cards have the same power consumption.Memory Bandwidth
Both cards have the exact same bandwidth, so in theory they should perform exactly the same. (explain)
Texel Rate
Both cards have the exact same texel fill rate, so in theory they should be equally good at at AF. (explain)Pixel Rate
Both cards have exactly the same pixel fill rate, so theoretically they should perform equally good at at FSAA, and be able to handle the same screen resolutions. (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.

Memory Bandwidth: Memory bandwidth is the max amount of data (counted in megabytes per second) that can be moved over the external memory interface in one second. The number is calculated by multiplying the interface width by its memory clock speed. If the card has DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's 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 processed per second. This is worked out by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.
Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
