It seems AMD is rolling out new revisions of its Polaris 10 and Polaris 11 GPUs with as much as 50% improvement in performance per watt. Both Polaris 10 and 11 happen to be the US-based chip maker’s latest products powering the midrange RX 470 and RX 480, as well as the mainstream RX 460 graphics cards.
The new GPUs will be initially made available in the embedded market under the monikers E9550 and E9260 before making their way to the consumer market later in the year. As of today, both the RX 470 and the RX 480 are based on the Polaris 10.
The 50% improvement in perf/watt was reportedly achieved by way of a much more refined binning process and significant enhancements to the 14nm metal mask layers. This revision will result in the TBP going all the way down to 95W from the earlier 150W on the RX 480, and to 50W from the earlier 75W in the Polaris 11-based RX 460. Not only that, the new products will also be offering a significantly better performance – e.g. a boost from 2.15 TFLOPS to 2.5 TFLOPS in the RX 460.
Following their availability in the embedded market, the updated revisions will be extended to the mobile market in the form of mobility Radeon RX 400 graphics card in the coming months. However, we are yet to be sure if/when these revisions will be made available in the desktop market.
