    Did you mean AMD is not beating Nvidia of late? I'm fairly sure AMD has beaten AMD every time.

    From what I've understood from this thread, this has also affected buyers who have done nothing but install the card and the new drivers. No tampering with clocks manually. You can't say that's not defective, unless you are a lawyer who used to work for Big Tobacco. It's not the customers' business if a card is not working out of the box. I don't see how this would have become such a scandal if only manually overclocked cards were crashing. It would merely mean there's no overclocking headroom.

    It would be better if it was software issue then it would be fixable like in amd case.

    On the plus side, all ti/super editions will excel in quality, as they'll be under extra scrutiny now. I was going to wait for the 20 GB 3080 or, taking the age of my system into account, the 16 GB 3070 anyway.

    Was NGG ever fixed on Vega?

    Well he has a point especially if you are an electrical engineer like him and you eyeball it and know its not a POASCAP. Its kind of like calling every small car a corolla even know its not. A POSCAP is a very specific Panasonic product of which no 3080 GPU is using. Sure its obscure for most but I do find it funny all these sites are porting them as POSCAP's. Everyone should have just said polymer electrolytic capacitors vs multi-layer ceramic capacitors.

    Palit is still okay there, they use 1 MLCC as MSI and many others, Zotac and Colorful I think use only POSCAP

    Hope this helps

    Thanks, Jura

    it wasn't ever "broken", however the way it is implemented on vega makes it extremely difficult to make it implicit at a driver level(i saw few emails on the linux mailing list a few years ago , alluding that there is a problem with vega hanging when switching between the old pipeline and the NGG pipeline which would make debugging difficult), hence why amd cancelled it and said that it would require an explicit implementation via new apis(like a vulkan extention).
    Ive heard that on mac it is exposed or was exposed via apple's metal api, but I cant confirm that.

    On navi the implementation problems have been addressed.

    ASUS owners are also reporting problems. I have a strix oc on preorder, luckily reckon I have the time to see how this pans out, I don't think the problem is 100% understood yet.

    Has everyone seen this in the meantime? Says to me that big Navi just beats the 3080 by 1-3%, could be why this Nvidia launch has been a disaster as they knew they had to get something out early and why they had to drop the titan branding to rebrand it a 3090 as the 'best' gaming card(titan was always mostly workstation) as it was the only way to guarantee a win against AMD. Big Navi, 80cu with 'real' numbers, not the stupid inflated core count Nvidia is trying to peddle. This launch has been a disaster for Nvidia, I just hope AMD can capitalize

    I got to side with CPC_RedDawn. It looks like the card is just boosting too much for the low quality component some AIB manufacturers have put in their cards. Low quality components not meeting the reference standard. The fix should be easy. Simply a new BIOS for those cards with less aggressive boost. Those cards will need to be re-reviewed though and yes it does suck for people who bought them. But i mean that's the risk you take for being an early adopter. I'll never understand people who buy a product in the first month. Personally i always wait at least 1 month and preferably two.

    I think people were overreacting with Ryzen 2 not reaching it's "up to" boost and the 5600XT bios "fiasco". Overall I always thought people overreact when AMD got launch problems. I wont be an hypocrite and turn around and criticize nVidia for not predicting AIB manufacturers would cheapen out on the caps. Not the first time a CPU or GPU got problem with boost. Don't think it's gonna be an issue long term outside of well people should have waited before buying as it's always the case and they'll end up with the wrong 3rd party card sadly. It sucks but it's on the manufacturer of the card.

    Only problem i see with this is nVidia went over the reference with their FE. If the reference would have been two sets of small caps like the FE then it could have made a different. FE should stick to the reference.

    Except 6x MLCCs means jack, as the TUF also crashes. JayZTwoCents will have a video about later.

    Something else is wrong with the 3000 series, cuz some people still report crashing despite underclocking by 100 MHz.

    If they make faulty POSCAP and MLCC configuration then the problem is in hardware , if this is hardware problem then product is faulty. if they lower the clocks in the new bios, it won't be the cards that the customers bought ;)
    for example: you bought a car, but the manufacturer has detected an engine fault that causes the car to go off. as a solution they will remove one cylinder for you :)

    Poor example.
    A bios can downclock and still be within the advertised boost range, just no OC or boost beyond the spec.

    If a car engine produces well above the advertised horespower and that causes problems, then the car maker can bring the HP back to advertised spec in order to fix the issue.

    I think that may be review models or early pics cos Jay2cent took one apart and this was not the case.

    The way I see it is that they state that base and boost clock is a guarantee anything above that is not. This is where the GPU boost algorithm takes over and looks at power, temps, etc, etc and boosts accordingly. There is no number advertised for this as every chip is different.

    Skip to 14:13, he proves my point

    Really the TUF crashes too. So maybe it has nothing to do with the caps? If it's the case then i take back everything i posted above.

    The problem here is that cards are crashing when not overclocked in any way. It seems that GPU boost is quite capable of crashing the card without any human help.
