Compare any two graphics cards:
GeForce GTX 1060 3GB vs Radeon RX 470 4GB
IntroThe GeForce GTX 1060 3GB comes with core clock speeds of 1506 MHz on the GPU, and 2000 MHz on the 3072 MB of GDDR5 memory. It features 1152 SPUs as well as 72 Texture Address Units and 48 Rasterization Operator Units.
Compare that to the Radeon RX 470 4GB, which comes with a clock speed of 926 MHz and a GDDR5 memory speed of 1650 MHz. It also features a 256-bit bus, and makes use of a 14 nm design. It is comprised of 2048 SPUs, 128 TAUs, and 32 ROPs.
Power Usage and Theoretical BenchmarksBoth cards have the same power consumption.
Theoretically speaking, the Radeon RX 470 4GB will be 7% faster than the GeForce GTX 1060 3GB in general, because of its greater bandwidth. (explain)
Texel RateThe Radeon RX 470 4GB will be a small bit (about 9%) faster with regards to texture filtering than the GeForce GTX 1060 3GB. (explain)
Pixel RateIf running with 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: Bandwidth is the max amount of information (measured in megabytes per second) that can be transported past the external memory interface within a second. It is worked out by multiplying the card's interface width by its memory speed. If it uses DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. 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 amount of texture map elements (texels) that can be processed in one second. This is calculated by multiplying the total texture units by the core clock speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.
Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
