Default AMD 20nm - R300 'Pirate Islands' Roadmap Leaked - 04-09-2014, 23:24 | posts: 9,283 | Location: UK

*Nothing mentioned in this leak is set in concrete, AMD is bound to change a few things here and there.

[Exclusive] [Editorial]: I have just recently gotten my hands on a somewhat outdated AMD Roadmap, the essentials of which should nonetheless hold true. The specifics mentioned in this post are liable to change and the primary focus of this leak is to serve as the basis of all future Pirate Islands speculation. This is going to be a very very interesting post, so buckle up, but keep that pinch of salt handy.

AMD Pirate Islands GPUs: R9 390X ‘Bermuda’ R9 380X ‘ Fiji’ R9 370X ‘ Treasure Island’

So lets begin, basically the AMD Roadmap shows three GPUs, the R9 390X, R9 380X and R9 370X, namely the Pirate Islands series. According to this roadmap all GPUs will be based on the TSMC 20nm Node and will be true Pirate Island cores, which is why nomenclature of the dies will be derivative in nature. Another thing mentioned is that all Pirate Island GPUs will have the DirectX 12 Hardware Feature Set. According to this roadmap the R9 370X is slated for announcement/arrival sometime this July-August this year. The R9 370X will feature a ‘Treasure Island XTX’ core and supposedly has 1536 Stream-processors, 96 Texture Units and 48 ROPs on the uncut die. Of course this road-map precedes the report we got of TSMC having a little trouble with 20nm so I am not sure how valid the time frame is anymore.

Now according to the road-map, we will see the R9 390X before the R9 380X. The R9 390X will feature the ‘Bermuda XTX’ core and feature a staggeringly high number of SPs, ie. 4224. The Texture Unit count is 264 with 96 ROPs. It is slated to show up late 2014 around November or so. Once again keep in mind the TSMC comment above. Finally the R9 380X which will feature the ‘Fiji XTX’ core and the following die configuration: 3072 SPs, 192 Texture Units and 72 ROPs and should appear sometime early 2015. Now interestingly the R9 390X ‘Bermuda XTX’ GPU is slated to have 512 Bits of Memory Bandwidth while as the R9 380X is slated to have 384 Bits with the R9 370X coming last with 256 Bits. Now the road-map even hints at the clock speeds of AMD’s future GPUs but I think it is prudent to mention that all these tech specs at this point in time are about as solid as the wind. However let us continue, with the help of this table:


* Values are not indicative of the final product.

Quote:
So summarizing, we have the first basic idea about the upcoming 20nm Pirate Islands GPUs from AMD. We know all of them should feature the DirectX 12 Hardware feature set and unless this road-map is completely off (very unlikely) then we will see Pirate Islands well before the year is over. Of course anyone could have figured out this road-map with a bit of common sense (Maxwell 20nm is due in about the same time frame of second half of 2014) but it helps to have solid and to the point information. So this is it folks, the first reference point to all future speculation and leaks on Pirate Islands from AMD.

Yeah, just checking because that's the last I read. I know it's rumours. In a way, I want AMD to come second this time. Let Nvidia come first, with whatever outrageous pricing they choose, then AMD comes, prices go down, Rob makes a purchase. Everyone happy.

Yeah, I think AMD should do that, it's only wise not to go first.

Just rumors, but either way doesn't affect what AMD does...unless TSMC can't pull off 20nm for some reason.

If that R9 390X spec is true... HOLY DAMN!!!

Think I will hold off getting a second 7970 til I hear more about that potential beast!

Speculation based at least partially on fact...

Quote:

Speculation based on the baseless idea that these companies actually have the ability to make abrupt and substantial architectural changes to a chip regardless of the fact that they're typically already in final production and would have to kill things full-stop, make changes, go through the tape-out process, obtain re-certification and approval, then re-start the entire pre production/ramping up/full production process all over again.

The only thing that can be done so far along is increase mem/core clocks if the silicon process is mature, with good enough yields, to allow for the additional voltage while avoiding leakage and other heat inducing factors.

The possible delay of nVidia's Maxwell has a direct correlation to when AMD will be able to release their chips because they're both being manufactured at TSMC and right now it seems TSMC's 20nm wafer capacity is completely booked till the end of Q3 2014 by smartphone and tablet manufacturers.


Just the facts Ma'am...

The production capacity of Taiwan Semiconductor Manufacturing Company (TSMC) has been booked through the end of the third quarter of 2014 thanks to orders from handset solution and PC chip vendors, according to industry sources.

The planned roll-outs of new smartphones by brand handset vendors and the upcoming 4G services in China have pushed chipset solution vendors to place wafer start orders at TSMC, the sources noted.

Consumer IC suppliers are also placing short lead-time orders at TSMC as demand from downstream and end-market device makers is likely to pick up soon, added the sources.

As a result, TSMC's 8- and 12-inch fabs are currently operating at 100% and over 90% of their capacity, respectively, said the sources, adding that the foundry's 20nm and 28nm production lines are fully occupied by orders for smartphone and tablet solutions.

AMD isn't limited to just TSMC. lol

AMD also has a deal with GloFo for GPUs... So, if TSMC can't put out GPUs for them, AMD can simply fall back to GloFo.

I do not see AMD going with 7GHz GDDR5 in 512bit configuration.
If you want to make bets, then it's more probable that top-end will have HBM instead.

The 380x is probably the card most people are waiting for... hence why it is coming out last .

I'm pretty sure the higher the memory bus, the lower the memory clock...

Damn they really are going for the 4K market.

I dont see them use only Glofo for gpu's ... I believe Glofo is more enclined to produce SOC, Nand in 14-16nm FinFet instead, just for grab as many money and marketshare possible..

Now we know that TSMC seems have some delay for mass production of 20nm ( high performance, we are not speaking about SOC ) ..

I saw on YT video from HW dev. conference where guy from TSMC showed their new roadmap and talked about High performance 20nm was not good enough (very small difference to low power draw tech) and basically there is no special high performance 20nm on TSMC (one tech. which scales power draw based on clocks), should be back with 14/16nm FinFET.

So 20nm TSMC will not bring maximum and therefore performance bump will be pretty nice with 14/16nm.

As for GloFo I am not sure here, but they should be capable to make similarly clocked GPUs as those present in APUs are decent overclockers even on 28nm. Proper question would be:
"What kind of power consumption we can expect from GloFo chips?" (because I have not seen any kind of measurement based on GPU in APU)

I use NVidia cards but gotta tell yea, AMD, stepping it up with performance while also keeping the compute side and bitcoin mining. Both companies have some serious awesomeness all around . Debating though..... grab a second GTX 780 Gaming edition, save a bit more and see how the 880 does, or see how the 390x does...... hmmm......

Second 780 and wait for Pascal or the successor to Pirate Islands.

Yea that's what I was thinking. I just tend to not go SLI but to buy the newest GFX card of the year. 580 when it came out, 680 when it came out and now 780. I'll have to think about it though. Thanks for the reply.
