Pascal: What do we know? Discussion, Latest News & Updates: 1000M Series GPU's

I was getting all excited for HBM2.

Ah, well gotta do something so we dont deflate the desktop users ego's.

i wonder if its going to retain full clock speeds etc of the desktop cards. they've proved they can do it and supposedly pascal is going to be more efficient.

HBM2 is too far down the pipeline.

Hynix began HBM1 production in Q3 2014 and AMD couldnt deliver HBM1 cards until June 2015 and yields was still a mess.
HBM2 production will begin at the start of Q2 2016 so I would guess HBM2 cards isnt available until around Q4 2016 at earliest with similar yields as AMD had I think.


So Nvidia can`t afford to wait til late 2016 before rolling out Pascal. Thats where GDDR5X comes in.

 

ahh, i have been hearing that samsung was gonna start cranking out HBM2 modules Q1 2016.

I suppose it dosent matter much, for I'll probably not have the funds to get anything equipped with pascal till Q3-4 anyways.

That's what a ton of tech sites are saying. I am just going to be pissed if they don't refresh mobile until Q3 2016, I really want a new laptop before next summer.

 

I really don't think that mobile is going to get HBM for awhile...

 

That may be true, but Micron is saying end of 2016 for GDDR5X, that would be a heck of a wait if the 1080/whatever its name is gets released in March.

 

I'm betting HBM2 will be in mobile, but limited to the top end cards, like the 980M replacement.

Haven't heard a peep about GDDR5X until now and we've known about HBM since 2013-2014. GDDR5X may be for special cards.

 

thats why im saying, mobile will most probably lack all the goodies that the desktop cards will be getting. dont get too hyped over HBM, ull just be disappointed in the end

I hope they're not creating GDDR5X to keep mobile and desktop performance distanced. That's just dumb.

They are more than capable of creating mobile GPU's with HBM2.

 

i think it might be more for intergrated systems, from the top of my head tablets, mac books, etc.

I tend to agree.

 

Will the pascal version upgrade from 970m be more powerful than the 980m? If so, how poweful?

Are you serious?

 

I dunno, breh. You tell me. Or is asking questions against TOS now?

Considering that this entire thread is devoted to answering your question, the only reasonable conclusion is that you could not be bothered to read any of it.

Then when you are called out on it you cop an attitude?

No soup for you!

I prefer toast with peanut butter.



I'll check back if there are news for this Pascal.

Traditionally speaking, the x70 of the new GPU ends up being just slightly faster than the x80 of the old GPU but nVidia has been doing all kinds of things lately so who knows. Its generally not worth the upgrade to the new GPU if you're going from x70 to x80 in the next generation but Pascal could be leaps and bounds better than Maxwell if the heat isn't an issue and there are many cases where the Maxwell 970 actually stomps my 780 Ti so Maxwell didn't really follow that path already.

 

Well.. they're just straight up putting desktop GPU's into boat anchor notebooks these days.. Why not HBM.

 

Because HBM would require a modification to MXM to support the larger die size. Unless you want everything to be soldered. Besides that, nVidia's real money is in desktop cards and HBM2 is going to be in short supply for awhile. I'm not saying we will never see it but look how long it took to get the 980 in laptops...

 

yupyup, people tend to go all kinds of crazy now that we got the 980 in mobile format. its DOESNT mean were going full desktop from now on, i DOESNT mean that mxm 3.0b is dead and it ALSO, MOST OF ALL, doesnt mean that mobile chips will be equal in specs to desktop cards from now on. the 980 is an absolute exception from the rule!

its like saying: oh look, theres the bugatti veyron with 1100+ HP, that means from now on every prius is gonna sport insane engines like that! mainstream powah for all!!!

nope, not gonna happen, so dont get your panties wet yet...

I wouldn't be all doom and gloom just yet, fellas. We really don't know what's going to happen. GDDR5X could just be for lower end cards, like the replacement for the 940M. HBM2 will be in mass production by the end of this year. This was confirmed pages back.

 

Why on earth would they throw a more expensive memory chip on a card that doesn't even max GDDR5 as it is?

 

Pascal may utilize it.

 

well, its not like the 980M doesnt profit from more bandwidth, it actually does so pretty significantly, especially when oced. its just that it would be too good to be true if ngreedia went HBM and/or GDDR5X on mobile right away with pascal...

 

This article makes a good argument for NVIDIA not using GDDR5X as a standard for their 2016 lineup of GPU's, but rather for a limited few.

It also explains a bit more about GDDR5X, for those who have no idea what the hell is going on.

 

What!? Six days and no updates?

It must have been cancelled.

No news is good news.

 

Well most of these pages aren't actually news or what we know, but speculations.

 

A mysterious GPU, code named "JM601," was spotted on shipping manifest with a price tag of $1139.

http://techfrag.com/2015/10/26/mysterious-jm601-gpu-from-nvidia-spotted-on-zauba/

If not Pascal, then maybe a GTX 990 dual-GPU card?

 

Considering that $1139 is actually a decent price for a dual-GPU flagship, I doubt that's what it is.

 

I remember when this thread was created and Pascal was but a distant dream. Now it seems like it might as well be launching tomorrow. It feels close.

Yeah, it probably isn't a 990. That's pretty cheap, unless that's the "invoice" price and not MSRP. It could also be a mobile Pascal GPU. Top end mobile cards are around $1000. Who knows... All speculation. All we know for sure is that NVIDIA has begun shipping them to laboratories for final testing before mass production.

@Cakefish: Yeah, it's not going to be too long now before we see some legit leaks.

 

I don't see a connector evident, but I do see a number of fastening holes, to me it looks like a daughter card to attach to another host board.

Could be an in place GPU upgrade for a new form factor delivery system - IDK what connector is on the bottom of that card.

Maybe a daughter card for a new high density compute platform; add a bunch of those to a host board that would be used for a compute cluster.

 

Pascal (for mobile especially) is still at least six months off... we have a lot of waiting (and more speculation) to do.

 

yay, let the fun / speculating continue

 

Currently, six months feels like a blink of an eye!

 

No worries then. 980M is performing well with 1080p 60 FPS DX11 games. This should arrive in time for DX12 gaming.

 

Are those HBM on the chip? And my guess would be it's for server/super computing.

 

Does anyone else think they might hold off HBM2 on mobile? Instead using GDDR5X for ram?

also i wonder how well the mobile will stack up with the desktop. as from what i have been seeing its supposed to be a very sizable jump in power savings.

Considering GDDR5X will double bandwidth and that mobile parts usually lack power vs desktop parts it will not matter if they do use it...then again mobile cards are expensive. Perhaps they will use HBM 2.

 

Yeah, though i wonder how far pascal mobile is going to lag behind the desktop, its been creeping up for some time. discounting the missing 20nm architecture i'd think they'd be rather close by now. (there is a graph for this)

As well as they have demenstrated they can stuff a suposedly more power hungry chip into a laptop and get away with it.

My take would be that desktop will see HBM2 mobile will get to have GDDR5X and we might get to enjoy closer levels of chip power.

I think HBM2 will be for the refresh of Pascal (2017). For mobile, that is. I'm sure desktop Pascal will have HBM2 by next summer.

Makes sense. Hope that's not the case but it probably is. GDDR5X is still more than twice as fast as GDDR5.

 

thats what im thinking, that or a "1080 for notebook" line. lol

I really don't know how much GDDR5X will improve things, given that current cards are not really memory bandwidth limited, especially at 1080p. Even at 1440p, overclocking the memory from 7 to 8GHz on my 980 Ti nets me a paltry 5-7% gain.

 

In my humble opinion, it is not likely that they will go that route. Their recent marketing campaigns for mobile GPUs boast about reducing gap between mobile and desktop. This is why we have things like GTX 980.It will not be inline with their strategy to keep HBM exclusive to desktops. However it is quite possible to have a mixed bag lineup similar to 800m series.

 

Well, if Pascal doubles core performance in comparison to Maxwell, then we could say we'll need close to double the bandwidth to ensure we don't remain bandwidth starved - this fits in quite nicely with the information out there that GDDR5X is twice as fast as GDDR5.

 

Pretty much exactly what I was going to say. I'm sure they will fully utilize GDDR5X. HBM2 has a fairly long lifespan.

GDDR5 would be a bottleneck for Pascal.

 

But GDDR5 still doesn't bottleneck even a Titan X though, meaning current GPUs just aren't bandwidth starved. While I get the point about Pascal being 2x more powerful, improving upon something that isn't a current bottleneck is unlikely to yield significant improvements. That's all I'm trying to say.
