GeForce GTS 250 1GB vs GeForce GTS 250 512MB
Intro
The GeForce GTS 250 1GB has core speeds of 738 MHz on the GPU, and 1100 MHz on the 1024 MB of GDDR3 RAM. It features 128 SPUs along with 64 TAUs and 16 Rasterization Operator Units.Compare all of that to the GeForce GTS 250 512MB, which features GPU core speed of 738 MHz, and 512 MB of GDDR3 memory running at 1100 MHz through a 256-bit bus. It also features 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 exactly the same memory bandwidth, so theoretically they should perform the same. (explain)
Texel Rate
Both cards have the exact same texel fill rate, so in theory they should perform equally good at at anisotropic filtering. (explain)Pixel Rate
Both cards have the exact same pixel rate, so theoretically they should be 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: Bandwidth is the largest amount of information (counted in megabytes per second) that can be transferred across the external memory interface within a second. The number is calculated by multiplying the bus width by its memory clock speed. In the case of DDR type memory, the result should be multiplied by 2 again. If it uses 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, High Dynamic Range and higher screen resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This is calculated by multiplying the total number of texture units by the core speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.
Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate 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 also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
