Compare any two graphics cards:
Geforce GTX 760 vs Radeon HD 4670 1GB
IntroThe Geforce GTX 760 has a GPU clock speed of 980 MHz, and the 2048 MB of GDDR5 memory runs at 1502 MHz through a 256-bit bus. It also is comprised of 1152 SPUs, 96 Texture Address Units, and 32 Raster Operation Units.
Compare all of that to the Radeon HD 4670 1GB, which comes with a GPU core clock speed of 750 MHz, and 1024 MB of GDDR4/GDDR3/DDR3/DDR2 RAM set to run at 1100 MHz through a 128-bit bus. It also is made up of 320(64x5) Stream Processors, 32 Texture Address Units, and 8 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically, the Geforce GTX 760 should perform much faster than the Radeon HD 4670 1GB overall. (explain)
Texel RateThe Geforce GTX 760 will be much (about 292%) more effective at anisotropic filtering than the Radeon HD 4670 1GB. (explain)
Pixel RateIf using a high resolution is important to you, then the Geforce GTX 760 is a better choice, 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: Memory bandwidth is the maximum amount of data (measured in MB per second) that can be transported past the external memory interface in a second. It's worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, 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 texture map elements (texels) that can be applied per second. This number is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.
Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
