Compare any two graphics cards:
Geforce GTX 680 vs Radeon HD 5750 1GB
IntroThe Geforce GTX 680 makes use of a 28 nm design. nVidia has set the core speed at 1006 MHz. The GDDR5 memory runs at a frequency of 1502 MHz on this particular model. It features 1536 SPUs along with 128 TAUs and 32 ROPs.
Compare those specifications to the Radeon HD 5750 1GB, which uses a 40 nm design. AMD has set the core frequency at 700 MHz. The GDDR5 RAM runs at a frequency of 1150 MHz on this particular card. It features 720(144x5) SPUs along with 36 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Performance-wise, the Geforce GTX 680 should in theory be much better than the Radeon HD 5750 1GB overall. (explain)
Texel RateThe Geforce GTX 680 will be much (more or less 411%) faster with regards to anisotropic filtering than the Radeon HD 5750 1GB. (explain)
Pixel RateThe Geforce GTX 680 is a lot (about 187%) more effective at AA than the Radeon HD 5750 1GB, and also will be able to handle higher resolutions without losing too much performance. (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 transported past the external memory interface in one second. It's calculated by multiplying the card's interface width by its memory speed. In the case of DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This number is calculated by multiplying the total texture units by the core clock speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.
Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
