GeForce GTS 250 1GB wins

(Based entirely on the benchmarks listed above)

When combining all game benchmark scores on this page together, the GeForce GTS 250 1GB wins overall, by 36 FPS. Please note that we do not have the results of every benchmark ever done for these cards, so the results may differ wildly in different games.

GeForce GTS 250 1GB 497 FPS
GeForce 9800 GTX 461 FPS
Difference: 36 FPS (8%)

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 9800 GTX 140 Watts
GeForce GTS 250 1GB 145 Watts
Difference: 5 Watts (4%)

Memory Bandwidth

Both cards have the exact same bandwidth, so theoretically they should perform the same. (explain)

Texel Rate

The GeForce GTS 250 1GB should be just a bit (about 9%) more effective at anisotropic filtering than the GeForce 9800 GTX. (explain)

GeForce GTS 250 1GB 47232 Mtexels/sec
GeForce 9800 GTX 43200 Mtexels/sec
Difference: 4032 (9%)

Pixel Rate

The GeForce GTS 250 1GB will be just a bit (about 9%) better at anti-aliasing than the GeForce 9800 GTX, and should be capable of handling higher screen resolutions better. (explain)

GeForce GTS 250 1GB 11808 Mpixels/sec
GeForce 9800 GTX 10800 Mpixels/sec
Difference: 1008 (9%)

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 (in units of megabytes per second) that can be moved across the external memory interface in a second. The number is calculated by multiplying the interface width by the speed of its memory. If the card has DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR 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 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 in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.

they're almost the same thing, i think i'll go with the gtx 250...but the gtx 9800 is also a good choice!!
