Compare any two graphics cards:
Radeon RX 470 vs Radeon RX 480 4GB
IntroThe Radeon RX 470 comes with 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 is comprised of 2048 SPUs, 128 Texture Address Units, and 32 Raster Operation Units.
Compare those specifications to the Radeon RX 480 4GB, which comes with GPU clock speed of 1120 MHz, and 4096 MB of GDDR5 RAM set to run at 1750 MHz through a 256-bit bus. It also features 2304 Stream Processors, 144 Texture Address Units, and 32 Raster Operation Units.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Performance-wise, the Radeon RX 480 4GB should in theory be just a bit better than the Radeon RX 470 in general. (explain)
Texel RateThe Radeon RX 480 4GB is quite a bit (more or less 36%) more effective at anisotropic filtering than the Radeon RX 470. (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the Radeon RX 480 4GB is superior to the Radeon RX 470, and very much so. (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 (in units of MB per second) that can be transferred over the external memory interface in a second. It's calculated by multiplying the interface width by the speed of its memory. If it uses DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This figure is worked out by multiplying the total texture units of the card by the core speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.
Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
