GeForce GTS 250 1GB vs GeForce GTS 250 512MB
Intro
The GeForce GTS 250 1GB features a GPU core speed of 738 MHz, and the 1024 MB of GDDR3 memory runs at 1100 MHz through a 256-bit bus. It also features 128 Stream Processors, 64 TAUs, and 16 Raster Operation Units.Compare all that to the GeForce GTS 250 512MB, which comes with a clock frequency of 738 MHz and a GDDR3 memory frequency of 1100 MHz. It also uses a 256-bit bus, and uses a 65/55 nm design. It is made up of 128 SPUs, 64 TAUs, and 16 Raster Operation Units.
Power Usage and Theoretical Benchmarks
Both cards have the same power consumption.Memory Bandwidth
Both cards have the exact same memory bandwidth, so theoretically they should have the same performance. (explain)
Texel Rate
Both cards have exactly the same texel 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 perform equally good at at 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: Memory bandwidth is the maximum amount of information (measured in MB per second) that can be transported past the external memory interface in a second. The number is calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This figure is worked out by multiplying the total number of texture units by the core speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.
Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write 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 core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
