Compare any two graphics cards:
GeForce GTS 250 1GB vs Radeon HD 5670
IntroThe GeForce GTS 250 1GB makes use of a 65/55 nm design. nVidia has set the core frequency at 738 MHz. The GDDR3 memory runs at a frequency of 1100 MHz on this particular card. It features 128 SPUs as well as 64 Texture Address Units and 16 Rasterization Operator 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 uses a 128-bit bus, and uses a 40 nm design. It is comprised of 400(80x5) SPUs, 20 TAUs, and 8 Raster Operation Units.

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)
In theory, the GeForce GTS 250 1GB will be 10% faster than the Radeon HD 5670 overall, due to its greater bandwidth. (explain)
Texel RateThe GeForce GTS 250 1GB should be much (about 205%) better at texture filtering than the Radeon HD 5670. (explain)
Pixel RateThe GeForce GTS 250 1GB should be a lot (about 90%) better at anti-aliasing than the Radeon HD 5670, and will be capable of handling higher resolutions without slowing down too much. (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 largest amount of data (counted in MB per second) that can be moved past the external memory interface in a second. It is calculated by multiplying the card's bus width by its memory clock speed. In the case of DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster 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 amount of texture map elements (texels) that are processed per second. This is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher this number, the better the graphics 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 most 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 calculated by multiplying the number of Render Output Units by the the core 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 fill 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 max fill rate.
