Compare any two graphics cards:
GeForce GTX 970 vs Radeon RX 470
IntroThe GeForce GTX 970 makes use of a 28 nm design. nVidia has set the core frequency at 1050 MHz. The GDDR5 RAM is set to run at a frequency of 1750 MHz on this specific model. It features 1664 SPUs along with 104 TAUs and 64 Rasterization Operator Units.
Compare all of that to the Radeon RX 470, which comes with a GPU core clock speed of 926 MHz, and 8192 MB of GDDR5 RAM running at 1650 MHz through a 256-bit bus. It also is comprised of 2048 Stream Processors, 128 Texture Address Units, and 32 Raster Operation Units.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
As far as performance goes, the GeForce GTX 970 should in theory be a bit superior to the Radeon RX 470 in general. (explain)
Texel RateThe Radeon RX 470 is a small bit (approximately 9%) faster with regards to anisotropic filtering than the GeForce GTX 970. (explain)
Pixel RateThe GeForce GTX 970 will be a lot (about 127%) better at AA than the Radeon RX 470, and capable of handling higher resolutions better. (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 largest amount of information (in units of megabytes per second) that can be transported past the external memory interface within a second. It is calculated by multiplying the card's bus width by the speed of its memory. If it uses DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, 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 texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.
Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the the card's 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 is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
