DX12/Vulkan can in theory bring us WORSE performance on the PC platform, if they don't spend the extra time optimizing/coding properly. Listen to the developers, they complain about DX12 being far more complicated and timeconsuming.

There has been many titles so far with worse performance in DX12 than DX11, both on AMD and Nvidia cards.

As i said, how could it be worse? Broken is broken, slightly less broken is irrelevant to me. The difference is that when a DX12 or Vulkan title is broken they won't be able to shift the blame to someone else, they will be responsible.

The big studios won't have a problem with DX12/Vulkan, so DX11 being easier doesn't matter to them, many broken ports like Unity wouldn't have had the issues they did if they didn't run into the limitations of DX11 in the first place, like draw-calls for example. Optimizing around the limitations of DX11 could be more time consuming/expensive for all we know than just doing it themselves. The small studios might struggle with it, but they can still use DX11 if it's to difficult, it's the AAA titles we need more performance from.

The only title i know that has shown a regression in performance on AMD hardware is Rotr, which is a GameWorks title (big surprise), they also state their DX12 implementation is in "beta". Mind sharing these many titles? Even Rotr shows a performance boost on AMD hardware if you have a weaker/older CPU.

That's what was being speculated afaik, don't know if things have changed or not. I haven't been following any rumors for awhile.

No idea, didn't even know about a 485. tongue.gif

As for the information well... it's scattered all over the place, don't feel like hunting a bunch of it down and condensing it here. There's speculation on it even outside of AMD and Nvidia such as TSMC's 16nm iPhone 6S and 6S+ SoCs vs Samsung's 14nm LPE process. The consensus is TSMC just have a more efficient/superior process currently. Of course AMD could of also just dropped the ball with Polaris too..

But i think the fact that AMD are using TSMC for their high performance chips is telling.

The one review of TSMC A9 vs Samsung 14nm lpe I did read had the samsung providing better battery life and slightly lower temps (toms). In terms of performance difference there really wasnt much of a difference, 1 to 3% normally going to the TSMC A9.

I doubt using TSMC for revisions of polaris and vega will provide direct efficency gains, but if 16nm TSMC can help GCN clock marginally better there will be that benefit to efficiency. I unfortunately doubt Vega will be clocking any higher than p10 at this point.

I never heard that being speculated at all. One day it was all news that AMD was using the GF/Samsung process and then all of a sudden there were a handful of people who started saying AMD was using TSMC too. Never once saw a single source on that and no one has been able to provide me a source the other couple times I asked.

Still wrong. Mafia 3 is DX11. Just to name one huge AAA title. It's mostly terrible Windows 10 Store exclusives that will get DX12, just to promote it and make people change to Windows 10. It brings nothing new to the table. Just like Gears of War DX12..

Games - people are playing - and will continue to play for a loong time, are DX11. AMD needs to fix their overhead and stop hoping DX12 / Vulkan will solve their problems over time. It will take years. Does AMD GPU owners have to suffer this long? A friend of mine with a 290X bought Fallout 4 on release, it ran terrible. Then he bought Doom, it ran terrible. It took weeks and months before these games ran good. This is AMDs big problem. They lack good performance on launch in the majority of games. Both games ran like a dream on Nvidia. Pretty much all games run good on Nvidia on release.

Are you just posting the db for hyperbole or are you doing it from ignorance? 30db-40db isn't a big difference.

Nvidia equally has their issues, I would know, I've only used Nvidia GPUs until recently.

A quick google search returned these.

http://wccftech.com/amd-arctic-islands-next-generation-graphics-16-nm-finfet-tsmc/

I get most of my info from the forums so.. Broken telephone? redface.gif

After some more searching it looks like Vega is now more or less confirmed to be on Global foundries, if AMD haven't stepped up big time then they're in trouble, at least in perf-per-watt..

Raja has made a point to discuss multi gpu several times now, improving frame time variance, scaling etc. Leads me to believe that AMD has a plan or knows more about what the future with dx12 could look like. Yes it's shifting to the devs, but even M$ has made efforts to make multi gpu easier on devs. If the new consoles run an apu along with a dedicated gpu, that would be a clown shoe sized foot in the door. With M$'s steps, and Raja discussing the future of multi gpu, I really feel like it's a strong possibility that the next Xbox will have multi gpu.

Edit: on mobile. I refresh, read, refresh, post, then read and topic has changed. Abandoning efforts till on desktop lol

Damn. I would never assume it'd sell that well. Well, either way, i'm glad it's a popular product.
