All the work for Polaris 13 was done, they need only schedule production basically. They wasted money, they did not save any, and if the Vega reception is anything to go by they may lose more from that decision. Releasing Polaris 13 late in 2016 would have just been the better financial move, but I think AMD expected more form Vega, that it promised much better performance on paper and that with Vega 11 and Vega 12 (with Vega 11 likely expected to compete with Polaris 13 in this scenario) they'd only end up with an exceptionally short run of an expensive to build GPU. Vega just did not pan out at all and it's barely meeting the potential of Polaris 13 while consuming an insane amount of power to do so. With Vega for 7nm being entirely scrapped I can only assume this means AMD knows what's wrong with Vega and it is utterly unfixable. I am very very interested in an indepth takedown on what is going on inside Vega, I want someone to tell me if the brakes failed and how on this train wreck.

Or it's some hilarious dumbshit like the TLB bug.

I think they did expect much better performance from Vega, it would explain why they did that whole "Poor Volta" thing, they thought they were going to make something significantly faster than whatever Nvidia could do. As far as Polaris, maybe Vega was someone's pet project and Polaris was trashed because of that? Oh well, we'll find out years from now if we find out at all.

Man, I wonder what's up with Raja going silent for the past few weeks, you'd expect him to be out there trying to do something, anything PR wise but he's just been silent, internal politics or something?

Finding out some time ago that 2816 shader Polaris was a thing before it got shelved and and shipped off exclusively to Bone Xs is pretty :cawg:

And wasn't it when yields on Polaris were improving rapidly? Holy poo poo

Just as I made a post about where AMD expected actual revenue to come from for Vega - https://globenewswire.com/news-rele...-MI-Series.html

If you're wondering where Vega is at all, well it looks like Apple and Baidu took them all. Maybe the earnings report will reveal a hilarious profit in GPUs for AMD regardless of the consumer disaster.

The biggest gains in compute datacenters came from AMD APUs though. Sure, you need to buy more chips, but they're cheaper and *far* more power efficient than cpu+dgpu combos for most compute tasks due to some memory bullshit.

Looking at the data, the frametime results for "High" are what most would consider normal. Some setting in this application's "Highest" preset is causing Vega huge problems right now.

Could it be related to the MSAA troubles that Vega has? I think that is one difference between the high and highest setting, SMAA vs MSAA

Destiny 2s highest preset does enable MSAA, but GN changed it to FXAA for their tests because Bungie says the MSAA path is still a work in progress. So it's not that.

It's probably one of the HBAO++++ things. It's a nvidia thing and it makes my 980Ti seem slow as a dead horse and outputs all the loving heat if I turn it on, and there's not even any perceptible difference between it and SSAO or whatever it's called.

Hmm, the highest AO setting is called "3D" which implies it's a world-space AO technique akin to Nvidia's VXAO. Bungie haven't said which algorithm 3DAO is based on, but if it's voxel based like VXAO then Vegas geometry bottleneck might be the problem.

Fast camera movement or a large number of moving objects would spike the amount of re-voxelization required per frame, which could push Vegas geometry processor over the edge and cause a stutter. That would explain the lulls where Vegas frametimes become smooth, if those are points where the scene is mostly static.

This was my assumption. They did note that 3DAO and DOF settings had the largest impact for an RX 580.

Like I said I can't imagine the boardroom is super happy with how this launch went, RTG can't keep stumbling through launch after launch. Their competitiveness is dropping further and further, by the time Vega is actually available in non-paper-launch quantities with actual working drivers it may be going up against Volta. And this time they can't even dump it in the x60 market due to excessive manufacturing costs.

The silence from Raja this past month has been notable and at this point I wouldn't be surprised to hear it's because he was attempting to justify his continued tenure as head of RTG. Navi is going to be a long time off, and if he whiffs again where does that leave AMD?

I just don't see Raja getting more than one additional shot at the brass ring here, and even that one seems iffy to me.

(on the "paper launch" note: on top of the report of "a few hundred units for the North America region", some people who backordered Vega 56 from Amazon yesterday are showing October ship dates)

[desire to know more intensifies]

Can you source this, or at least make a plausible argument for Polaris 13's existence? Also, can you source 7nm Vega being off the roadmap?

I'm a little dubious on the former. XB1X is a semi-custom SOC and the fact that XB1X has a bigger-than-P10 GPU doesn't prove a bigger-than-P10 standalone mask exists. On the other hand I don't think scaling GCN is as difficult as some people think it is, I don't fully understand why 4x 1024-core partitions would be some hard limit. Nothing is ever as easy as "just stamp out another shader engine" in practice but the engineering problems involved seem straightforward.

If the latter is true then holy poo poo, I've been musing about whether Vega is actually a solid enough base to build Navi on, and dropping Vega derivatives from the roadmap would be a massive red flag that AMD has absolutely no confidence in Vega.

I agree with the general thrust of your argument though. Around the end of Q1 2016 was when AMD dropped Fat Polaris, so I'd say at that stage they must have been confident that Vega would be releasing in Q4 2016, and that it would be competitive. Then it whiffed hardcore on performance, they probably expected it to be 30-50% faster than it actually was.

I don't tend to weight the whole "poor volta" thing too seriously, I think it was a throwaway jab from marketing rather than a serious attempt to telegraph that they were going to smoke Volta, but I would say that it probably shows they still had at least some confidence as late as the beginning of Q1 2017. By the start of Q2 they obviously knew it was going to be a dud and went radio silence, then lately of course we've gotten the blind-taste-test and other bullshit.

Early leaks mentioned a 7nm Vega20 coming in 2H 2018, but the official roadmap from a few months ago only slates Vega for 14nm and 14nm+. Presumably Vega20 was abandoned.

I'm using Polaris 13 to refer to fat Polaris considering Polaris 10, 11 and 12 codenames are taken up. Sorry for any confusion. Repiv sources my source of Vega being dropped just below your post.

Also the issue with scaling GCN seems to be the 64 ROP barrier, not so much the shader limit. Adding more shaders past 3584 (possibly 3072) is quickly diminishing returns with 64 ROPs, and from what I can tell GCN can't just double the ROPs.



There is no way Raja isn't in danger of losing his job. No one pulls such a hard duck and cover and have fellow employees risk their reputation on poo poo like this unless it's that serious.
