It looks like AMD is rolling out revisions to its Polaris 10 and Polaris 11 GPUs that result in a massive 50% increase in performance per watt. The new GPUs will be available to the embedded market first under the E9550 and E9260 naming, and will make their way to consumer products at a later date. Currently, the RX 480 and RX 470 are built around Polaris 10, with the RX 460 leveraging Polaris 11.
The gains in efficiency are attributed to a more refined binning process as well as enhancements to the 14nm metal mask layers. The revision will see the TBP go from 150W to less than 95W on the RX 480, and will see the Polaris 11-based RX 460 go from 75W to less than 50W. The revised GPUs will also be able to deliver more performance, with the RX 460 seeing a boost from 2.15 TFLOPS to 2.5 TFLOPS.
Following their availability in the embedded market, the revised GPUs will likely be rolled out to the mobile segment given the efficiency gains. Meanwhile in the desktop segment, AMD is set to unveil its high-end Vega 10 GPU with HBM 2 memory sometime before the end of the year.
