GeForce 9800 GTX+ vs GeForce GTS 250 512MB
Intro
The GeForce 9800 GTX+ comes with a GPU 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 Stream Processors, 64 Texture Address Units, and 16 Raster Operation Units.Compare all that to the GeForce GTS 250 512MB, which uses a 65/55 nm design. nVidia has clocked the core frequency at 738 MHz. The GDDR3 memory runs at a speed of 1100 MHz on this model. It features 128 SPUs as well as 64 Texture Address Units and 16 ROPs.
Power Usage and Theoretical Benchmarks
Both cards have the same power consumption.Memory Bandwidth
Both cards have the exact same memory bandwidth, so in theory they should perform the same. (explain)
Texel Rate
Both cards have the exact same texel rate, so theoretically they should be equally good at at AF. (explain)Pixel Rate
Both cards have exactly the same pixel rate, so in theory they should be equally good at at FSAA, 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 largest amount of data (in units of megabytes per second) that can be transferred over the external memory interface in one second. The number is worked out by multiplying the bus width by its memory speed. If it uses DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster 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 can be applied in one second. This figure is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The higher this number, the better the 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 amount of pixels that the graphics chip can possibly write to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the clock speed of the card. 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 many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.

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.
