    So, we get essentially a tech preview with the frontier edition in late june and something we can buy a month later.

    So... 27th of July... technically July, practically August and with unknown availability.

    Can't wait to hear from our educated friend LordEC911

    You guys really expected Vega to beat the 1080 Ti & Titan Xp ?

    AMD was handing over all the tell signs that it isn't going to and all that mystery behind it was pointing towards a rather good delay.
    If they had a sufficient Titan Xp killer, trust me, they'd be showcasing all sorts of benchmarks at GDC, not at Computex, nor at Siggraph, nor in late August.

    In order to have a balanced field in the GPU area like we now have in the CPU area, AMD needed Vega to be some sort of miracle, leapfrogging the f*ck out of their previous offerings and leaving the Titan Xp a good 20% behind ( in order to be in the "trade blows generation after generation, refresh after refresh" between them and NVIDIA [ think GTX 580 -> 7970 -> GTX 680 -> 7970 GHz -> 780 Ti era ] ).

    Beating 1080ti is another thing. I m talking about marketing side but not the possible hypes or other things. I am talking about the delay. Even they can't make a softlaunch on computex... and If I get it right Q1 launch will not going to happen either. And of course a datacenter product named vega which nobody will buy won't count. So still 27th of july launch can be a soft one. And maybe even september cant happen.

    Showing a one minute game play of a player who doesn't like to move too much on a system dual vega system with new ryzen without any performance indicators is more than a disaster. Showing these on computex may be the best they can do or amd may have nothing to the with the delay or etc. but all of these hurt them a lot.

    It is not consideration, it is a fact.

    Not all are capable to "get" it, though.

    And btw, just to throw the last tidbit of quality, AMD crаp gonna be offered in 2 versions vega 10 and 11. Computex had 10 running. 11 is coming at a later(quiet a bit) date. So if someone here wants performance, better buy NV here and now and stop listening to all these BS sht about volta. It is a very long time till it will come out.

    Arguing on performance or release date or things like these which will become known in the future is just for fun never forgot this please.

    While I am upset that we couldn't see anything useful about vega on computex the main problem still is on the marketing side. There is no way AMD doesn't know the things going on internet and everybody got himself ready to see a launch on computex. They should have said that it will not going to happen on computex before that press conference.

    They are shooting themselves in the knees.

    Now Koduri said on I don't remember, was it Twitter or on Reddit, that the 2* RX Vega Prey demo was "above 60fps" ( he could've said like "above 80fps" ), and "running comfortably above *any* single gpu card out there".

    Is @LordEC911 ok ?
    He's gone missing ( probably in the adventures of finding the RX Vega )

    6-8months ? Eh. I consider it a long time.
    Its still to be seen how much better volta is going to be(than pascal). Things arent really what they seem.
    I just want to know, what went wrong with vega, maybe its still fixable.484mm2 chip, on 14nm. Thats a big ass chip with absurd power consumption, and performance nowhere to be found.
    I mean if they would shrink hawaii and make it bigger a bit faster and give it the same 300W tdp it would be faster.
    Polaris is more than half the size ! And has slow bandwith.

    From my understanding, in the short version, the main problem is that AMD bet big on HBM2 and it back fired.

    See below, for more details on the long version: Some info taken from Nvidia's SC15 GPU Tech Theater

    On further explaining the next generation GPU architectures and efficiency, Stephen pointed out that HBM is a great memory architecture which will be implemented across Pascal and Volta chips but those chips have max bandwidth of 1.2 TB/s (Volta GPU). Moving forward, there exists a looming memory power crisis. HBM2 at 1.2 TB/s sure is great but it adds 60W to the power envelope on a standard GPU. The current implementation of HBM1 on Fiji chips adds around 25W to the chip. Moving onwards, chips with access of 2 TB/s bandwidth will increase the overall power limit on chips which will go from worse to breaking point. A chip with 2.5 TB/s HBM (2nd generation) memory will reach a 120W TDP for the memory architecture alone, a 1.5 times efficient HBM 2 architecture that outputs over 3 TB/s bandwidth will need 160W to feed the memory alone.

    Hold on. HBM was supposed to be the "power saver" for the GPU memory architecture.
    Anyhow, we have 484GB/s on vega, so thats less than half of this 60W power figure, that would put HBM power consumption in vega at around 30W maybe less.Thas less than GDDR5/x/6.
    And The cards are supposed to eat up 300-400W. HBM doesnt really explain Vega for me.
    Fiji had 4 stacks of HBM1, Vega has 2 Stacks of HBM2 at LOWER bandwith and still eats anyhwere between 25 and 100W more than Fiji! Something more is wrong here.
    I know that HBM2 availability was a thing that surely went wrong for AMD. But i dont know about the power consumption and performance.

    That's the key..."supposed to" is turning out to not. One of the two main reasons nvidia hasn't switched to HBM2 for consumer grade products availability and power consumption. It's shown right in the link directly from nvidia this was a major concern for them.

    I get that HBM2 in the near future is going to be a power problem. But according to this slide, Vega is at most at the "unhappy" emoji phase, which means still better (lower) power consumption for the memory subsystem than the gddr5. Isnt it ?
    I mean, remember, it has TWO SLOW HBM2 stacks, thats in contrast with FOUR FASTER HBM1 stacks of Fury X. its not even at 0.5TB/s yet, and you are talking about a problematic 1,2TB/s+ speeds.That cant explain a 100W+ power envelope over FURY.
    I only see it as a major AMD fckup, or GLOFO`s fault.

    @SinOfLiberty
    Is vega 11 the same chip with disabled CU`s ,or is it a separate chip ?

    HBM requires no memory controller so the net is supposed to be more efficient. the problem is that it still needs a memory controller.

    It is way more cut down w/o HBM2

    It is all a load of bull.. As in practice, Power Consumption goes out of the window once the card is clocked beyond certain frequencies. In case of AMD, dat huge аss number of W`s comes from exactly that. The chip is running at its highest freq, that the hardware is capable of.

    But again, this is not how it will be marketed as. Just an extra option for OC`ers and reviewers to demonstrate what the card is really capable of when pushed to max.

    Unhappy emoji phase is actually 4 stacks, look at the projected bandwidth (1000 GB/s), 2 stacks HBM2 should be AT HBM 4 stack power consumption or less. Anyone thinking the HBM2 is using lots and lots of power is probably wrong, the 2 stacks should be at least 2x the perf / watt of GDDR5 @ <250 GB/s and 3x+ perf / watt of GDDR5 @ ~500GB/s.

    Further backing this up is the mem VRM on the Vega FE card, OnSemi NTMFD4C86N which is only going to do about 25-30 amps @ 1.2-1.3v <40w

    It is absolutely mind-blowing to think that Zen and Vega are both on 14nm LPP considering how great Zen is and how poorly Vega is performing.

    How do you know this?

    Look - there aren't even ES samples of Vega 11 yet nor have there ever been and I don't think we'll see one.
    Vega 10 should easily scale down to the 150w TDP range Polaris 10 occupies. My bet is that Vega 11, if a design actually existed, has been cancelled.

    Leaked Q4'16 slides with Vega 11 show it slotting in for inference applications below Vega 10 but today we have the Radeon Instinct MI8 instead, a 175w R9 Nano in new clothing. The MI8 for FP32 most likely matches or beats the MI25 in performance / watt at stock performance levels.

    Vega 11 wouldn't make sense unless it is equipped with the same FP16 capability as Vega 10 and extremely huge GDDR5X bus and 20GB+ GDDR5X...but then again, it would use way more power than Vega 10 due to the GDDR5X power consumption.

    I dont know. But Vega 11 on GDDR5(x), as in smaller ANOTHER chip, would be a very welcomed thing for AMD.Yes Vega 10 can scale down.
    But its BIG, it needs HBM2, it needs inerposer. A smaller chip (much cheaper to produce) on a widespread cheap memory is certainly something that AMD needs...

    What worries me is that at least NOW, it seems, that polaris has more performance for mm2/hz(up to 1300mhz or so).So that could be a reason to can it, or maybe rework it.
