GeForce 9800 GTX+ vs GeForce GTS 250 1GB
Intro
The GeForce 9800 GTX+ features a core clock speed of 738 MHz and a GDDR3 memory frequency of 1100 MHz. It also uses a 256-bit memory bus, and uses a 55 nm design. It is made up of 128 SPUs, 64 Texture Address Units, and 16 ROPs.Compare all of that to the GeForce GTS 250 1GB, which comes with GPU clock speed of 738 MHz, and 1024 MB of GDDR3 RAM running at 1100 MHz through a 256-bit bus. It also is comprised of 128 SPUs, 64 Texture Address Units, 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 bandwidth, so theoretically they should have the same performance. (explain)
Texel Rate
Both cards have exactly the same texel fill rate, so theoretically they should be equally good at at anisotropic filtering. (explain)Pixel Rate
Both cards have exactly the same pixel fill 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: Bandwidth is the max amount of data (counted in MB per second) that can be moved across the external memory interface in one second. It's calculated by multiplying the interface width by its memory clock speed. If it uses DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the 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 texture map elements (texels) that are applied per second. This number is calculated by multiplying the total texture units by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.
Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly write to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
