AMD to release Radeon RX 470 and RX 460 in early August
AMD will release the Radeon RX 470 on August 4, and the RX 460 will also be on sale from August 8. In addition to the release dates, the full specifications of the video cards are also known. The RX 460 will also find its way into laptops.
The news has not yet been officially announced by AMD, but VideoCardz has put the slides online on which all information about the release of the Radeon RX 470 and RX 460 can be found. The video cards are positioned below the RX 480, which has been available since the end of June.
Like the Radeon RX 480, the RX 470 is based on the Polaris 10-gpu, but four compute units are disabled, so that the cheaper video card has 2048 instead of 2304 stream processors. Furthermore, the RX 470 has a lower clock speed, from 926MHz with a boost to 1206MHz. The memory is also clocked slower, with a speed of 1650Gbit/s. The RX 470 has 4GB GDDR5 memory and a 256bit memory bus. The memory bandwidth is therefore 211 GB/s. According to AMD, the card’s consumption is 120W.
For the Radeon RX 460 AMD uses a smaller gpu: Polaris 11. Like Polaris 10, it is baked on the 14nm finfet process. The GPU has 896 stream processors, 48 TMUs and 16 ROPs. The clock speed is 1090MHz with a boost to 1200MHz. There will be variants with 2GB or 4GB GDDR5 memory, which has a speed of 1750Gbit/s. Because a 128-bit memory bus is used, the bandwidth is 112GB/s. The video card should consume less than 75W, as there is no pcie power plug present.
From the slides it can be concluded that the RX 460 also appears in laptops. HP says it will use the video card in a new model from the Omen series. According to AMD benchmarks, the GPU is 1.2x faster than the Nvidia GTX 960M.

It is not yet known which suggested retail prices the RX 470 and RX 460 will receive. Manufacturers are expected to announce their own versions of the video cards on Thursday. A photo published by VideoCardz already shows a Sapphire version of the RX 460. No reference designs of the video cards will be released.
