In fairness, a car is different from a GPU core. A 1070 core is basically just a bigger 1060 (and only 50% bigger at that) core whereas a Corvette is an entirely different build/quality/construction/etc... compared to a Malibu. 

I was going into the weeds, I was bored.

Yea, this is really the most important piece of information we need to find out. IF vega 10 is 1080 tier, vega 11 is probably going to stomp on the 1080ti, which may be why we've seen some talk of volta.

and it had better stomp pascal since AMD has taken so much time and are launching so much later. If they merely match high end pascal at a competitive price sure it will be a good buy for anybody who needs a new GPU... but it will underwhelming after all this time.

 

they need to take the high end crown for a few months before volta launches. It will be good for the radeon brand. It's ok if volta takes it back at the end of 2017 because then AMD navi will again launch a few months after that.

there might be something to the rumors that vega is bigger than 4096, why i say this?, well its simple, the die showed is too big, its around 500mm2-580mm2 of area, it seems to be just a bit smaller than a fury x, and with a node shrink using 280x to rx 480 size diference taking CU numbers into account, (a 280x has 2048 cus and is 352mm2, a rx 480 is just 232mm2 with 2304 cus) a 14nm finfet furyx would be 347mm2 which is much smaller than the shown vega gpu.

its so much bigger we could fit a 5248 core gpu, assuming it has the same density (CUs/mm2), a gpu that size with a 1200mhz frequency would mean 12.5Tflops, and at 1500mhz would mean 15.7TFLOPs, 

a 4096 core would be 1200mhz =9.8 tflops at 1500mhz =12.2Tflops

If  that happens

1)RIP Savings

2) I am opening an  overseas shopping account because r/hardwareswap is  going to be awesome

 

In ask fairness both me(1070) and  my dad(1080)  would  be dying to upgrade our rigs and the real winner would be my brother(750ti)  as  he gets to keep either of the cards

 

Although what I  hope

Small Vega >= pascal  (launch  in summer)

Volta >> Small Vega (launch b4 Halloween)

Large Vega > Volta (lets say 10%) 

Launch by new year 2018  then the market would be interesting

(Also RIP gtx 970/rx480-owners )

Why what's wrong with your current GPUs?

Am I the only one questioning whether the chip Raja Koduri was holding is the same one that was running Doom at 4k? I have serious doubts that a GPU that big would perform so poorly in Doom, which also happens to very much be very much an AMD title. It's not even that much smaller than Nvidia's P100...

Well, AMD themselves said it was their top-end Vega GPU. I have no clue which one Raja Koduri is holding here, or if it was the same one running that Doom demo. Could be a sneak peek to an even bigger Vega GPU.

AMD VEGA 10 and VEGA 20 slides revealed.
 

So VEGA 10, coming in a few months with 16GB of HBM2.
Although not sure what VEGA x2 is. Dual GPU card, or VEGA 11.

I too thought dual GPU but then the TDP is only 75 watts higher than normal vega 10?? I don't think it will be dual GPU in the way the 295x2 or 7990 was. I.e. I don't think it will use crossfire. Probably AMD has a hardware solution whereby they can put 2 x vega 10 chips together and their resources are combined with the application being oblivious...

 

and wtf vega 20 in late 2018?? Isn't that firmly navi territory ? Although it does look like a monster and it's 7nm.

Thank you very much for that.

 

Going to the OP.

1st half of 2017? Usually it means Q2, so May at the earliest with June\July more likely and August for any decent 3rd party custom designs. AMD why u make us wait dis long?

I'd say the same timeframe as Polaris. Announcement at an AMD event, paper launch at Computex, release in July.

they must be trying to get higher clocks on vega 20, thats the only reason why someone would double the memory speed on the same core

Yeah, most likely. I will hold out hope for retail units of vega+zen available at Computex but chances are bleak

They said 1H 2017, if it's July I won't be particularly happy.

 

I think probably towards the end of Q2 Mid/Late May early June.

Release at around Computex instead of just a paper launch.

 

Makes sense. I have this feeling nVidia targets that too for a 1080Ti launch.

Probably they have their own event that's a paper launch like what they had in Macau but sooner than it was last year, and then probably launch at computex or a bit before. I think we'll probably see AIB card designs around April and them starting to hit shelves around mid/late May. Of course the reference designs going up first. Hopefully AMD can ensure that finding an RX 500 (or whatever their 1070 price and performing equivalent will be) won't be as hard as it was to get a RX 480 when it was launched. Since there seems to be less hype around this launch, this might be a bit better.

Navi is all about scalability, where multiple GPU cores are seen as a single core, and work as a CPU essentially, with the VRAM as a cache between them all.

I doubt it'll be ready by 2018 if they really want it to work that well. Who knows Maybe VEGA 20 is a stop gap to it, or is significantly better than VEGA 10.

We really don't have any idea, but this is a funky road map.

I think the most important thing on those slides is about Vega 20 and xGMI, "Support for peer to peer GPU communication". Global Memory Interconnect (GMI) is AMD's answer to the issues of communication between CPUs and GPUs plus other memory systems in a multi-chip module (MCM) package, basically an APU for what we'll see.

 

Quote

AMD's GMI - Global Memory Interconnect, extends the coherent fabric between chips on the same multi-chip module (MCM) package. The coherent fabric extends between packages using combo phys which also support PCIe interconnection.

http://wccftech.com/amd-coherent-interconnect-fabric-gpus-cpus-apus/

 

Ok so that was GMI but what is xGMI? Which quite clearly states is about inter GPU communication. I suspect this is AMD's answer to the issues of coherent multi GPU compute workloads, what this means for crossfire and games I have no idea but hopefully it's good news and not something exclusive to the server/data center market like NVLink is.

 

If xGMI could be used to put more than one GPU die on a card and more effectively make use of those resources than crossfire can well I am all for that.

What I meant was that they both are the same architecture and thus share a similarly proportional build cost whereas a Corvette and a Malibu are entirely different and thus the build/material costs aren't relatable.

Probably a GMI solution will consume less power than the PLX chips used for previous dual gpus

Moreover, look at Fiji. They were able to cut 100W of power from the Fury X by lowering clocks and binning a bit more the full chip --> R9 Nano

Put two together and you're done, it's just a matter of low stock voltage/clock and binning.

The same is happening currently with the RX lineup. At launch you'd have a really hard time getting an RX480 that pulled 150W while overclocked. Now we see them do 1400+ MHz easily while not consuming more than 140W.
