Compare any two graphics cards:
GeForce GTX 970 vs Radeon RX 470
IntroThe GeForce GTX 970 comes with a GPU core speed of 1050 MHz, and the 4096 MB of GDDR5 memory runs at 1750 MHz through a 256-bit bus. It also is comprised of 1664 Stream Processors, 104 Texture Address Units, and 64 Raster Operation Units.
Compare all that to the Radeon RX 470, which features a clock frequency 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 made up of 2048 SPUs, 128 Texture Address Units, and 32 Raster Operation Units.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Performance-wise, the GeForce GTX 970 should in theory be a little bit better than the Radeon RX 470 in general. (explain)
Texel RateThe Radeon RX 470 is a small bit (more or less 9%) faster with regards to anisotropic filtering than the GeForce GTX 970. (explain)
Pixel RateThe GeForce GTX 970 is a lot (more or less 127%) better at full screen anti-aliasing than the Radeon RX 470, and capable of handling 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: Bandwidth is the max amount of data (measured in MB per second) that can be moved across the external memory interface within a second. The number is calculated by multiplying the card's bus width by its memory speed. In the case of 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 number of texture map elements (texels) that can be processed in one second. This number is worked out by multiplying the total texture units by the core clock speed of the chip. The better this number, the better the video 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 most pixels the video card could possibly write to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
