Compare any two graphics cards:
GeForce GTX 1060 3GB vs Radeon RX 470 4GB
IntroThe GeForce GTX 1060 3GB uses a 16 nm design. nVidia has clocked the core frequency at 1506 MHz. The GDDR5 memory runs at a frequency of 2000 MHz on this particular model. It features 1152 SPUs along with 72 Texture Address Units and 48 ROPs.
Compare those specifications to the Radeon RX 470 4GB, which features a GPU core clock speed of 926 MHz, and 4096 MB of GDDR5 memory set to run at 1650 MHz through a 256-bit bus. It also is comprised of 2048 Stream Processors, 128 Texture Address Units, and 32 ROPs.
Power Usage and Theoretical BenchmarksBoth cards have the same power consumption.
Theoretically, the Radeon RX 470 4GB should perform just a bit faster than the GeForce GTX 1060 3GB in general. (explain)
Texel RateThe Radeon RX 470 4GB is a little bit (about 9%) better at AF than the GeForce GTX 1060 3GB. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the GeForce GTX 1060 3GB is a better choice, by a large margin. (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 data (measured in megabytes per second) that can be transported over the external memory interface in a second. It's worked out by multiplying the interface width by its memory speed. If it uses DDR RAM, the result should be multiplied by 2 once 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 AA, High Dynamic Range and higher screen resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This number is calculated by multiplying the total texture units by the core speed of the chip. The better the texel rate, the better the graphics 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 maximum number of pixels the video card could possibly record to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few 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.
