Compare any two graphics cards:
Geforce GTX 760 vs Radeon R9 270
IntroThe Geforce GTX 760 comes with a GPU core clock speed of 980 MHz, and the 2048 MB of GDDR5 RAM runs at 1502 MHz through a 256-bit bus. It also features 1152 SPUs, 96 Texture Address Units, and 32 ROPs.
Compare those specifications to the Radeon R9 270, which uses a 28 nm design. AMD has clocked the core speed at 900 MHz. The GDDR5 memory works at a frequency of 1400 MHz on this specific card. It features 1280 SPUs as well as 80 TAUs and 32 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
In theory, the Geforce GTX 760 is 7% faster than the Radeon R9 270 overall, due to its greater data rate. (explain)
Texel RateThe Geforce GTX 760 will be much (about 31%) better at texture filtering than the Radeon R9 270. (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the Geforce GTX 760 is a better choice, but only just. (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 MB per second) that can be transported over the external memory interface in a second. It is calculated by multiplying the bus width by its memory speed. In the case of DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This figure is worked out by multiplying the total number of texture units by the core clock speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.
Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
