Compare any two graphics cards:
GeForce GTS 250 1GB vs Radeon HD 5670
IntroThe GeForce GTS 250 1GB features a clock speed of 738 MHz and a GDDR3 memory frequency of 1100 MHz. It also features a 256-bit bus, and uses a 65/55 nm design. It is comprised of 128 SPUs, 64 TAUs, and 16 Raster Operation Units.
Compare all of that to the Radeon HD 5670, which comes with a clock speed of 775 MHz and a GDDR5 memory speed of 1000 MHz. It also features a 128-bit bus, and makes use of a 40 nm design. It is made up 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)
As far as performance goes, the GeForce GTS 250 1GB should in theory be a bit superior to the Radeon HD 5670 overall. (explain)
Texel RateThe GeForce GTS 250 1GB should be a lot (more or less 205%) better at anisotropic filtering than the Radeon HD 5670. (explain)
Pixel RateThe GeForce GTS 250 1GB is quite a bit (more or less 90%) better at FSAA than the Radeon HD 5670, and also will be capable of handling higher screen resolutions better. (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 data (counted in MB per second) that can be moved past the external memory interface in one second. It's worked out by multiplying the interface width by its memory clock speed. In the case of DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This is calculated by multiplying the total texture units by the core clock speed of the chip. The better the texel rate, the better the graphics 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 number of pixels that the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
