Compare any two graphics cards:
GeForce GTX 1060 3GB vs Radeon R9 270X
IntroThe GeForce GTX 1060 3GB makes use of a 16 nm design. nVidia has set the core frequency at 1506 MHz. The GDDR5 memory works at a frequency of 2000 MHz on this specific model. It features 1152 SPUs as well as 72 Texture Address Units and 48 ROPs.
Compare all that to the Radeon R9 270X, which features a clock frequency of 1000 MHz and a GDDR5 memory frequency of 1400 MHz. It also uses a 256-bit bus, and makes use of a 28 nm design. It features 1280 SPUs, 80 TAUs, and 32 Raster Operation Units.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
In theory, the GeForce GTX 1060 3GB will be 10% quicker than the Radeon R9 270X in general, because of its greater data rate. (explain)
Texel RateThe GeForce GTX 1060 3GB is a lot (more or less 36%) better at AF than the Radeon R9 270X. (explain)
Pixel RateIf using high levels of AA is important to you, then the GeForce GTX 1060 3GB is a better choice, and very much so. (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 information (in units of MB per second) that can be transported across the external memory interface in a second. It is calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR RAM, it must be multiplied by 2 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 is calculated by multiplying the total texture units of the card by the core 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 in one second.
Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as 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 bandwidth is, the lower the potential to get to the maximum fill rate.
