Compare any two graphics cards:
GeForce GTX 1060 3GB vs Radeon RX 480 4GB
IntroThe GeForce GTX 1060 3GB makes use of a 16 nm design. nVidia has set the core frequency at 1506 MHz. The GDDR5 RAM is set to run at a frequency of 2000 MHz on this card. It features 1152 SPUs along with 72 TAUs and 48 ROPs.
Compare all that to the Radeon RX 480 4GB, which uses a 14 nm design. AMD has set the core speed at 1120 MHz. The GDDR5 memory is set to run at a speed of 1750 MHz on this card. It features 2304 SPUs as well as 144 Texture Address Units and 32 Rasterization Operator Units.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The Radeon RX 480 4GB should in theory be just a bit faster than the GeForce GTX 1060 3GB in general. (explain)
Texel RateThe Radeon RX 480 4GB should be much (about 49%) faster with regards to AF than the GeForce GTX 1060 3GB. (explain)
Pixel RateThe GeForce GTX 1060 3GB will be much (approximately 102%) more effective at full screen anti-aliasing than the Radeon RX 480 4GB, and will be able to handle higher screen resolutions without losing too much performance. (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 (measured in megabytes per second) that can be transported over the external memory interface in a second. It is worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.
Pixel Rate: Pixel rate is the maximum number of 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 clock speed of the card. 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 fill rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
