GeForce 9800 GTX+ vs GeForce GTS 250 512MB
Intro
The GeForce 9800 GTX+ features a GPU core clock speed of 738 MHz, and the 512 MB of GDDR3 RAM runs at 1100 MHz through a 256-bit bus. It also is made up of 128 SPUs, 64 Texture Address Units, and 16 Raster Operation Units.Compare that to the GeForce GTS 250 512MB, which comes with a core clock frequency of 738 MHz and a GDDR3 memory speed of 1100 MHz. It also uses a 256-bit bus, and uses a 65/55 nm design. It features 128 SPUs, 64 TAUs, and 16 ROPs.
Power Usage and Theoretical Benchmarks
Both cards have the same power consumption.Memory Bandwidth
Both cards have the exact same bandwidth, so theoretically they should have identical performance. (explain)
Texel Rate
Both cards have exactly the same texel rate, so theoretically they should perform 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 full screen anti-aliasing, and be capable of handling 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: Memory bandwidth is the largest amount of data (counted in MB per second) that can be moved over the external memory interface in a second. The number is calculated by multiplying the bus width by the speed of its memory. In the case of DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.
Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum 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.
