AMD teases Polaris 10 and 11 GPUs- teases Polaris 10 die

AMD (NASDAQ: AMD) has launched a new page on their website, dedicated to their forthcoming Polaris GPU architecture, with one especially interesting tidbit: a partial shot of the Polaris die. the folks over at Videocardz were able to produce a complete die shot from it, along with providing an estimation of the die size. Their estimates correspond to an earlier leak (which was quickly taken down) and presumably confirms that the Polaris 10 die will be 233 mm2 in size.

AMD has teased die shots of its upcoming GPUs in the past, Fiji being the most recent example and they were successfully analyzed to give an accurate representation of not only the die but its components as well. In what appears to be history repeating itself, AMD has published teasers of both Polaris 10 ad Polaris 11 on its new page. Given below are the die reconstructions courtesy of Videocardz:

AMD Polaris 10 reconstructed die shotAMD Polaris 11 die shotAMD Tonga and TahitiAccording to AMD, Polaris 11 will be positioned at the entry level desktop and mainstream notebook segments, and the bigger Polaris 10 will be positioned at the mainstream desktop and high-end notebook segments. The expected TDP of Polaris 11 (codenamed Baffin) is at an impressive 50 Watts and the TDP of the Polaris 10 (codenamed Ellsemere) is expected between 110 and 150 Watts.

 

According to the information known about the 14nm LPP process, and based on transistor density increase, a 232mm² GPU would be roughly equivalent to a 464mm² 28nm processor – at the same TDP levels. Since we already know that AMD is going to be focusing not just on performance but power efficiency as well, it may well be possible that this number could be much higher.

 

AMD has also been significantly touting a 2.5x increase in efficiency over their previous generations. If that number is correct, then theoretically speaking, the Polaris 10 GPU should be able to provide the same performance as a 580mm2 die. However,  accounting for leakage when clocking at high rates, the actual numbers may be lower than the estimates given by AMD. Also, we do not know what kind of power efficiency mix AMD is playing with here so it would be pointless to speculate further about the exact performance levels at this point, especially considering that AMD is expected to fully announce Polaris at Computex.

The Estimated specifications of the Polaris 10 and Polaris 11 based video cards are given below. Polaris 11 is expected to be used n 6 dGPUs and Polaris 10 in 2 dGPUs.

Please note that the specifications are purely speculations based on previous generation GPUs and leaks, and official specifications will only be available when AMD announces the Polaris GPUs, possibly at Computex.

I started gaming with Minesweeper on my dad's office computer that ran Windows 95 and have been hooked since. I've spent many hours on classics like Wolfenstein 3D and today, I spend several more on games like Deus Ex, Darksiders, Just Cause and keep a special place in my heart for BioShock and Metro 2033. I may have a background in computer science, but I aspire to write and direct a film adaptation of S.T.A.L.K.E.R.: Shadow of Chernobyl and Call of Pripyat one day. I love cats, cooking and light, soothing music. Huge Godzilla fan.
