I'm not necessarily buying it either but you gotta admit it's a really cool idea and would drop like an atom bomb on the gpu scene. It would be a clever innovation and something to get people talking about AMD. Plus, you still could use the individual chips in 470-esque sku's while catching everybody by surprise with a legitimate 1080 competitor.

It's total fan fiction but it's a fun idea!

Oh, it's definitely an interesting idea, and no doubt we'll be there someday, but I don't see it on the current roadmap. Maybe by the time Navi rolls around.

Yeah, might show up when HBM or whatever next generation memory is planned gets cheap enough to use in the $100-300 bracket. So 2018 or beyond.

It's definitely coming with Navi, my biggest question is how they're going to remove the "dev problem".. Without a revolution in how chips communicate it would be a fail.

The fact that Navi is specifically targeting scalability must mean they've either broken that barrier, or the next consoles will pack more than a single chip, the risk would be insane if they left it up to developers. I wonder if Polaris and Vega would try to link up to two chips together, and Navi could scale with like 4-8 very small chips?

Exciting stuff ahead, even if Navi is the first time we see it.

Think they will introduce the tech in the Next Gen consoles - multiple chips on one interposer. It's clear that Navi will be using this technology.

Perhaps, they will work with Nvidia on a standard going forward; that should help get it off the ground. It's a win-win for both companies, better yields.

i think if they make something open standard, it will help whole semiconductor industry, from cpus/gpus to alot of other stuff. win for everyone. thumb.gif

Your idea of an atom bomb for the GPU market is a bit much.

Although a different method, the performance and similar idea have been used in the past. That is to use 2 midrange chips on a single card to reach high end performance. The results and sales have generally been the same and that is generally an unsuccessful product as far as sales go. This would not be any different because CF has awesome scaling when it works. The problem is the software support and that would not change with two GPU on a single interposer. All it would do is create nightmares for RMA's, more difficulties in manufacturing and increase the failure rate of the product. One chip failing, would mean scrapping the whole card. Looking at past history is why this product wouldn't do as well you might think.

The prime example of this is Voodoo technologies last products or voodoo 5 and any videocard from asus which tries to make a dual GPU card with midrange chips. All these chips were priced around the price of a single GPU flagship or less but offered better performance overall. The exception to the rule that sold well was the gtx 690, but this was a flagship x2, which is people in the dual card market want.

Personally, I might consider buying one at 500 dollars, a dual Polaris 10 I mean. Certainly a more likely purchase than 700 dollar founders edition 1080, but I don't the market would accept it very well, particularly if the leaked 3dmark scores are true. Most people who want to buy a dual flagship class GPU card, not a dual midrange to get to flagship.

The problem is most people in the market for dual GPU cards are looking for better than single gpu flagship performance. And not just by a little bit, but alot. Otherwise products using 2, gx104 chips would have been more succesful aside from the gtx 690.

If AMD was capable of putting two 120watt product on an interposer, what would be an atom bomb is if Zen performs like haswell or better and AMD puts a polaris 10 chip on it and sells it for 300 dollars. That would be revolutionary. Better than console APU's is something people want and I am surprised AMD has not done yet.

Not 2 small dies performing like a larger single one or even out performing it. That has been done to death and isn't any more novel than the original Fury Nano design, which atleast had a unique niche.

A setup with a communication "hub" chip or one of the GPUs acting as such on interposer for low latency and speed could show itself as a monolithic GPU to the software developers

wow they'd need to put a gun to my head to sell me a dual-GPU card right now in mid 2016 (be it Nvidia or AMD)

not until those are made perfect and have absolutely 0 issues of any kind compared to single chip .. which Im sure is still well away



also I agree that a dual GPU is for a true flagship - to crank out as much as possible and beat a single chip flagship

not to make Polaris10 be able to take on a 1080

This talk about multiple chips on one interposer is specific to Navi - based off of everything that is currently known.

480x2 isn't going to be coming to market - there isn't the ecosystem for it.

Anyways - don't think there has much discussion about the Primitive Discard Accelerator. IMO - this is what will bury GP106.
