Compare any two graphics cards:
GeForce GTX 480 vs Radeon RX 470
IntroThe GeForce GTX 480 has a GPU core speed of 700 MHz, and the 1536 MB of GDDR5 memory runs at 924 MHz through a 384-bit bus. It also is comprised of 480 Stream Processors, 60 TAUs, and 48 ROPs.
Compare all that to the Radeon RX 470, which has a clock speed of 926 MHz and a GDDR5 memory speed of 1650 MHz. It also uses a 256-bit bus, and makes use of a 14 nm design. It features 2048 SPUs, 128 TAUs, and 32 Raster Operation Units.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
As far as performance goes, the Radeon RX 470 should in theory be just a bit better than the GeForce GTX 480 overall. (explain)
Texel RateThe Radeon RX 470 is much (about 182%) more effective at AF than the GeForce GTX 480. (explain)
Pixel RateThe GeForce GTX 480 should be a small bit (about 13%) more effective at AA than the Radeon RX 470, and also should be able to handle higher screen resolutions without slowing down too much. (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 transferred past the external memory interface in a second. It is worked out by multiplying the interface width by its memory clock speed. If it uses DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This is calculated by multiplying the total number of texture units by the core speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.
Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly write to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs 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 output rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
