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 clocked the core speed at 738 MHz. The GDDR3 RAM is set to run at a frequency of 1100 MHz on this model. It features 128 SPUs as well as 64 TAUs and 16 Rasterization Operator Units.
Compare those specifications to the Radeon HD 5670, which comes with a core clock frequency of 775 MHz and a GDDR5 memory frequency of 1000 MHz. It also uses a 128-bit bus, and makes use of a 40 nm design. It features 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)
Theoretically, the GeForce GTS 250 1GB should be a small bit faster than the Radeon HD 5670 in general. (explain)
Texel RateThe GeForce GTS 250 1GB is quite a bit (about 205%) faster with regards to AF than the Radeon HD 5670. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the GeForce GTS 250 1GB is superior to the Radeon HD 5670, by far. (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: Bandwidth is the largest amount of information (counted in megabytes per second) that can be transported past the external memory interface in a second. It's calculated by multiplying the interface width by the speed of its memory. In the case of DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This figure is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.
Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate 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 outputting the pixels (image) to the screen. The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
