Compare any two graphics cards:
GeForce GTS 250 1GB vs Radeon HD 5670
IntroThe GeForce GTS 250 1GB features a GPU core clock speed of 738 MHz, and the 1024 MB of GDDR3 RAM is set to run at 1100 MHz through a 256-bit bus. It also is made up of 128 SPUs, 64 TAUs, and 16 Raster Operation Units.
Compare that to the Radeon HD 5670, which features a clock speed of 775 MHz and a GDDR5 memory speed of 1000 MHz. It also makes use of a 128-bit memory bus, and makes use of a 40 nm design. It is made up of 400(80x5) SPUs, 20 TAUs, and 8 ROPs.

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 28 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.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
As far as performance goes, the GeForce GTS 250 1GB should in theory be just a bit better than the Radeon HD 5670 in general. (explain)
Texel RateThe GeForce GTS 250 1GB will be much (more or less 205%) more effective at AF than the Radeon HD 5670. (explain)
Pixel RateThe GeForce GTS 250 1GB will be quite a bit (about 90%) faster with regards to AA than the Radeon HD 5670, and able to handle higher screen resolutions while still performing well. (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.
Please note that the price comparisons are based on search keywords - sometimes it might show cards with very similar names that are not exactly the same as the one chosen in the comparison. We do try to filter out the wrong results as best we can, though.
Memory Bandwidth: Memory bandwidth is the maximum amount of information (counted in megabytes per second) that can be moved past the external memory interface within a second. It is calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR type RAM, it must be multiplied by 2 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, High Dynamic Range and higher screen resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total amount of 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 most pixels the video card could possibly write to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on many 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.
