GeForce GTS 250 1GB vs GeForce GTS 250 512MB
Intro
The GeForce GTS 250 1GB features a clock frequency of 738 MHz and a GDDR3 memory speed of 1100 MHz. It also makes use of a 256-bit bus, and uses a 65/55 nm design. It features 128 SPUs, 64 Texture Address Units, and 16 Raster Operation Units.Compare those specs to the GeForce GTS 250 512MB, which has a clock speed of 738 MHz and a GDDR3 memory frequency of 1100 MHz. It also features a 256-bit bus, and makes use of a 65/55 nm design. It is made up of 128 SPUs, 64 TAUs, and 16 ROPs.
Power Usage and Theoretical Benchmarks
Both cards have the same power consumption.Memory Bandwidth
Both cards have exactly the same memory bandwidth, so in theory they should perform exactly the same. (explain)
Texel Rate
Both cards have exactly the same texel rate, so in theory they should perform equally good at at AF. (explain)Pixel Rate
Both cards have exactly the same pixel rate, so theoretically they should perform equally good at at FSAA, 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 maximum amount of information (measured in megabytes per second) that can be transferred past the external memory interface in one second. It's worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR type RAM, it must be multiplied by 2 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 AA, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This figure is worked out by multiplying the total number of texture units by the core clock speed of the chip. The higher 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 most pixels the video card can possibly write to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units 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 output rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
