GeForce 9800 GTX+ vs GeForce GTS 250 512MB
Intro
The GeForce 9800 GTX+ features a GPU clock speed of 738 MHz, and the 512 MB of GDDR3 memory runs at 1100 MHz through a 256-bit bus. It also is made up of 128 SPUs, 64 Texture Address Units, and 16 ROPs.Compare that to the GeForce GTS 250 512MB, which features a GPU core clock speed of 738 MHz, and 512 MB of GDDR3 memory running at 1100 MHz through a 256-bit bus. It also is made up of 128 Stream Processors, 64 Texture Address Units, and 16 ROPs.
Power Usage and Theoretical Benchmarks
Both cards have the same power consumption.Memory Bandwidth
Both cards have exactly the same bandwidth, so in theory they should perform 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 be equally good at at AA, and be able to handle 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 max amount of information (in units of MB per second) that can be transferred past the external memory interface in a second. It is calculated by multiplying the interface width by its memory clock speed. If it uses DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This is calculated by multiplying the total texture units by the core clock speed of the chip. The higher this number, the better the 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 maximum amount of pixels that the graphics chip could possibly record to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.

Comments
One Response to “GeForce 9800 GTX+ vs GeForce GTS 250 512MB”I have a Diamond Radeon 5850 I flashed the wrong bios on trying to customize the clock and fan.(broke my heart) Anyway I bought a PNY 9800 GTX+ 512 used for 35 bucks at a local computer store that has some nice used parts. The 9800 GTX+ really surprised me. It actually plays GTA IV at the same settings and more smooth. I can't understand why the 5850 would not do as well. Anyway its a decent card for good price I recommend it. And if the GTS 250 is the same I recommend it too.
