We have a small update to our previous story.

AMD Radeon R9 M480 has Polaris GPU

According to our sources upcoming Radeon R9 M480 mobile graphics card will feature Polaris GPU. This is in fact a confirmation of our previous post, where it seemed reasonable to believe that R9 M480 and R9 M490 were the only mobile Radeon M400 cards that would not be rebranded using older silicons. Well as it turns out, we were right.

The R9 M480 GPU has Device ID of 67E0, which as you might remember from this story, is actually Baffin aka Polaris 11.

AMD Radeon M480 is equipped with 4GB GDDR5 memory clocked at 1250 MHz, the GPU clock is set to 1000 MHz, although it may vary depending on supplier.

It appears that both R9 M480 and R9 M490 series will feature new Polaris chips. Despite rather unconfirmed nature of Polaris specifications, we do know that full Polaris 10 is equipped with at least 2304 Stream Processors, and Polaris 11 features at minimum 1280 unified cores.

Therefore AMD Radeon M480 may feature cut-down silicon, whereas Radeon M480X should receive full fat Polaris 11 GPU. Although AMD may decide to skip R9 4xxX and R9 485/495 series to simplify their offer.

Stay tuned for more news about Radeon M400.
