GeForce GT 340 vs GeForce GT 340 1GB
Intro
The GeForce GT 340 has a GPU clock speed of 550 MHz, and the 512 MB of GDDR5 RAM is set to run at 850 MHz through a 128-bit bus. It also features 96 SPUs, 32 Texture Address Units, and 8 Raster Operation Units.Compare all that to the GeForce GT 340 1GB, which comes with a clock frequency of 550 MHz and a GDDR5 memory frequency of 850 MHz. It also features a 128-bit bus, and makes use of a 40 nm design. It is made up of 96 SPUs, 32 TAUs, and 8 ROPs.
Power Usage and Theoretical Benchmarks
Both cards have the same power consumption.Memory Bandwidth
Both cards have the exact same bandwidth, so theoretically they should perform exactly the same. (explain)
Texel Rate
Both cards have exactly the same texel fill rate, so theoretically they should perform equally good at at AF. (explain)Pixel Rate
Both cards have the exact same pixel rate, so in theory they should be equally good at at full screen anti-aliasing, and be capable of handling the same 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 information (counted in megabytes per second) that can be moved across the external memory interface in one second. The number is calculated by multiplying the card's interface width by its memory speed. In the case of DDR memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, 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 processed per second. This number is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.
Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly record to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the the core 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 is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
