GeForce GT 240 GDDR5 vs GeForce GT 240 GDDR5 1GB
Intro
The GeForce GT 240 GDDR5 has a GPU core speed of 550 MHz, and the 512 MB of GDDR5 RAM runs at 850 MHz through a 128-bit bus. It also is comprised of 96 Stream Processors, 32 TAUs, and 8 ROPs.Compare those specifications to the GeForce GT 240 GDDR5 1GB, which uses a 40 nm design. nVidia has clocked the core frequency at 550 MHz. The GDDR5 RAM works at a frequency of 850 MHz on this particular model. It features 96 SPUs along with 32 Texture Address Units 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 have the same performance. (explain)
Texel Rate
Both cards have the exact same texel 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 AA, and be capable of handling 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: Bandwidth is the max amount of data (measured in MB per second) that can be transferred across the external memory interface in one second. It is worked out by multiplying the interface width by the speed of its memory. If the card has DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better 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 in one second. This number is worked out 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 applied per second.
Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
