AMD Fiji GPU 'Not Arriving Soon Enough' - Will Possibly Have Stacked dRAM (HBM) Memory

[Rumor] Earlier we begin, a brusque reminder that this post is tagged every bit rumor, and so take it with that famous compression of salt. The aptly named SemiAccurate.com has published something that sounds quite interesting. The article hints at some unique characteristic in Fiji GPU and and then simply states that it wont be arriving for a while. Because I didn't cough up a thousand bucks, I can literally see only 3 lines of text and I am not sure what to make of it. AMD Pirate Islands GPUs Bermuda Fiji Treasure Island

AMD Will Probably Feature HBM Stacked Memory in Republic of the fiji islands GPU - Not Coming Soon

I will attempt to deduce annihilation and everything from these lines, and so this article is mostly pure educated speculation. If this isn't your cup of tea, you lot might desire to skip this write up. Basically the commodity hints that: "AMD's upcoming Fiji has something fun, something that volition provide some very interesting numbers". At present depending on when Fiji launches, it might exist based on the 20nm node only that isn't actually something unique or 'fun' equally Charlie puts it. Its simply standard lithographic progression so I very much uncertainty he is referring to that. No, in my opinion in that location is just one feature that fits the pecker and that is HBM or stacked dRAM if you may. There is a very very huge amount of evidence on AMD working on stacked dram for graphical uses and this seems like the ideal fit to "something fun". An alternative would be an ARM cadre on the GPU but somehow I recollect thats as well much of a long shot.

Nosotros know for a fact that AMD is working with Hynix to introduce HBM into its graphical solutions and I have found bear witness of as big every bit 8-How-do-you-do HBM Stacks. For the nomenclature averse, this means eight stacks of dRAM cadre dies with the control dice at the bottom and TSVs (through silicon vias) connecting the stacks. HBM uses a very low amount of voltage (1.2V) and delivers upto 256 GB/s (8-Hi) per chip of throughput which is quite an insane amount. In comparing modern GDDR5 ram delivers merely 28GB/s per chip. Now hither is the affair, the very shoddy leak nosotros received a long time back was only good for a few facts, and one of these was the nomenclature of AMD's R9 300 GPUs. Because of that we know that Republic of the fiji islands XTX is non actually the highest end fleck, rather Bermuda XTX is (unless AMD has decided to practise a shuffle). So why exactly is the source talking about Republic of the fiji islands like that? Well, if I were to take a guess at AMD's road map, I would say that Fiji XTX is probably 28nm with HBM while Bermuda XTX is 20nm with HBM. Or it could be that Fiji is 20nm with HBM while Bermuda is 28nm without HBM, that would fit in with the leak mentioned above since it said that Bermuda would arrive first. The three lines say its not arriving soon, but of class I have no idea weather not arriving soon is described as past months or years or what.
