Compare any two graphics cards:
Geforce GTX 760 vs Radeon R9 270
IntroThe Geforce GTX 760 comes with a core clock speed of 980 MHz and a GDDR5 memory frequency of 1502 MHz. It also makes use of a 256-bit memory bus, and uses a 28 nm design. It features 1152 SPUs, 96 TAUs, and 32 Raster Operation Units.
Compare all that to the Radeon R9 270, which features a core clock frequency of 900 MHz and a GDDR5 memory frequency of 1400 MHz. It also makes use of a 256-bit memory bus, and makes use of a 28 nm design. It features 1280 SPUs, 80 Texture Address Units, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically speaking, the Geforce GTX 760 should be a little bit faster than the Radeon R9 270 overall. (explain)
Texel RateThe Geforce GTX 760 should be a lot (about 31%) faster with regards to AF than the Radeon R9 270. (explain)
Pixel RateThe Geforce GTX 760 will be a little bit (more or less 9%) better at FSAA than the Radeon R9 270, and able to handle higher screen 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 max amount of information (in units of megabytes per second) that can be transferred across the external memory interface within a second. It is calculated by multiplying the bus width by its memory clock speed. If it uses DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better 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 processed per second. This number is calculated by multiplying the total number of texture units by the core speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.
Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends 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 max fill rate.
