AMD working on Tonga GPU

[TOMPPIX]

AMD Tonga, GCN redesigned once again?

First rumors about Tonga surfaced more than a year ago. It was listed in a BETA Catalyst driver along with Hawaii and Vesuvius. The last two are already here, but Tonga was still being polished.

Tonga is not a single island, but an archipelago of 176 islands. Those islands have some piracy history, but we are not convinced this is a Pirate Islands’ chip. In fact, you will get much more results by looking for Tonga’s volcanoes.

First and foremost, Tonga is a mainstream processor, which is probably manufactured by Global Foundries. It will introduce some major changes to the architecture; however, if you expect 20nm fabrication process and High-Bandwidth-Memory, then you will be disappointed. So what is so special about this processor? Tonga is most likely a direct competitor to NVIDIA’s Maxwell GM107. AMD has been actively improving GCN architecture to increase power efficiency. Tonga will bring a dramatic change in terms of power consumption, something you would not expect from AMD anytime soon. Tongan architecture is also said to feature new PowerTune Boost, which would operate at much lower hardware level.

Of course Tonga would also support all technologies known from other GCN 1.1 and GCN 2.0 GPUs: Mantle, TrueAudio and maybe even XDMA CrossFire.

 

AMD Radeon R9 2×5

Graphics card based on Tonga should be released in about two to three months. The sad news is that Tonga-powered graphics card will only feature 2GB memory (at least the reference model).  This basically means we have a new Pitcairn (Curacao) replacement.Probably the the most suitable name for this card would be R9 275X, but from what we’ve learned, final codename has not yet been decided.

AMD will probably talk more about its new GPU behind closed doors at Computex meetings, which starts in about 19 days, so stay tunned for more information.

Sounds tasty...

 

 

 

 

 

 

Tonga, no? k den

awesome

So no flagship and another lame low end gpu? no thank you...

I first read that as Tonka, like the truck. It would have been hilarious if they had misspelled as Tonka in the leak.

OT: this looks pretty cool!

People are gonna go nuts if it's an 85W TDP R#-255. Think 750Ti, but AMD.

Honestly, if it really is a pitcairn replacement, I don't see why it'd be a 275/275X. As AMD usually does, they'd prefer to put it in a place where they have no competitive products. Right now, that is in the $150-$165 and $210-$235 price range for the 750Ti and 760. If it were truly a Pitcairn replacement, they'd be starting at around where the 7850 lies for HD 7000s. That's where the R7 260X sits right now for RX 200 cards in terms of performance. Otherwise, they'd have to sit it inbetween the 270X and 280, which is right in the middle of Tahiti country and 2GB of memory makes no sense there (edit: What is stacked VRAM? Maybe then it makes sense).

I'm more keen to believe it'll be something low-cost and easy to actually calm the TDP of: A replacement for Cape Verde + Bonaire, the R7 + HD 7700 series cards. Like I said, think NVidia and the GTX 750Ti but with AMD. Start off easy, then drop into the pit with a bunch of cards along the same principle (power efficiency with little sacrifice to performance in this case, to compete with GTX 800s).

Fun fact: Tonga is a bunch of islands known for their friendly residents and lots of immigration from there to other countries. It's not going to be a Radeon R9 390X that's 3x as fast as a 780Ti, lol. Closer definition to Barnie than an atomic bomb going off when it comes to relating architecture names to GPU performance.

I swear to god, if this ends up being inflated as hell like the Rx cards were, I am going to knock some heads together. Even though I will never get the money for one. I'll just do it to be nice to those of you that can afford them.

Jet Engines need 2 or more of those, I think we'd need more than 1.

Umm, you do know that high end Maxwell cards are coming, possibly soon in fact, and that these cards will likely try to compete with a potential Maxwell flagship and not the 750ti?

I suppose this must be the actual card, minus shroud?
