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 exactly the same memory bandwidth, so theoretically they should perform the same. (explain)

Texel Rate

The GeForce GTS 250 1GB will be a small bit (more or less 9%) faster with regards to texture 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 should be a small bit (more or less 9%) faster with regards to AA 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: Memory bandwidth is the max amount of information (in units of megabytes per second) that can be transferred over the external memory interface in a second. It's calculated by multiplying the interface width by its memory clock speed. If the card has DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The better this number, the better the graphics 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 most pixels that the graphics chip can possibly write to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max 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!!
