Compare any two graphics cards:
Radeon RX 470 vs Radeon RX 480 4GB
IntroThe Radeon RX 470 uses a 14 nm design. AMD has set the core speed at 926 MHz. The GDDR5 RAM is set to run at a frequency of 1650 MHz on this particular card. It features 2048 SPUs as well as 128 TAUs and 32 ROPs.
Compare those specs to the Radeon RX 480 4GB, which uses a 14 nm design. AMD has clocked the core frequency at 1120 MHz. The GDDR5 memory works at a frequency of 1750 MHz on this particular model. 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)
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 should be quite a bit (approximately 36%) better at anisotropic filtering than the Radeon RX 470. (explain)
Pixel RateThe Radeon RX 480 4GB should be a lot (approximately 21%) more effective at anti-aliasing than the Radeon RX 470, and will be 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 largest amount of information (in units of megabytes per second) that can be moved past the external memory interface in a second. It is worked out by multiplying the bus width by the speed of its memory. If it uses DDR memory, the result should 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 anti-aliasing, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.
Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the the core clock speed. 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 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.
