the 14LPP process is average at best
I actually disagree here. Ryzen at 2-3 Ghz is extremely efficient, better than intel in fact.

I said this in the rumor thread, that these might be a flawed revision and the RX model a re-spin.My bet is the Vega FE cards have early silicon with a bad stepping, some critical flaw that was patched in BIOS/Drivers with a large performance penalty, thus delaying the retail RX Vega cards for a new stepping to build enough quantity to ship to AIBs, whilst the older flawed stepping stock was quickly gobbled up internally by AMD to create an emergency "Prosumer" card which wouldn't be hurt as much by the performance penalty. Just a thought but didn't some industry insiders tweet AMD intentionally delayed Vega and that it was a bold yet worthwhile move? This could be it.
Ryzen is great, very efficient design yes I agree there, 14nm lpp is very good at low frequency targets, goes drastically down hill past 3.5ghz and falls off of a cliff at 4ghz with ryzen CPU.I actually disagree here. Ryzen at 2-3 Ghz is extremely efficient, better than intel in fact.
GTX 1050 Ti can go to ~1900 MHz, while TSMC chips go to ~2100 MHz, right? So it is ~10% difference. It is important, but not that much. It means with TSMC AMD could have 10% less CUs (smaller chip size) for the same performance. If GF is 10% cheaper than TSMC, than it doesn't matter. And I believe that is the case, since AMD is probably GF's biggest customer, while TSMC would give priority to Apple and nVidia and maybe even some other companies. It might be AMD got more than 10% better price form GF than from TSMCLast year nvidia launched the 1050 which was using the 14nm lpp and it got lower frequencies if my memory serves me correctly when compared to 16nm tsmc, it's unusual to see smaller GPUs of the same uarch clock lower than their bigger die cousins.
Then you you have the "3rd gen Lpp" Rx 580 debacle which is actually LESS efficient than its one year earlier Rx 480 "second gen" 14nm, it got really bad power consumption for just 5% perf improvement with a full year of revision.
EDIT; Just to add, I strongly feel if Amd wasn't tied to global foundries and could have secured 16nm FF+ we would be seeing 10-15℅ higher frequencies across all of AMDs >100w products, just my 2 pence worth.
Here is mine GTX1070 OCDisqus user #define is back at it again: https://disqus.com/home/discussion/...mance_benchmarks_detailed/#comment-3391224760

That's roughly 2x470 CF. There has to be something wrong.Disqus user #define is back at it again: https://disqus.com/home/discussion/...mance_benchmarks_detailed/#comment-3391224760

We also don't know if Pascal architecture has a hard 2100mhz limit, meaning the difference maybe slightly more than 10%, but that's purely conjecture on my part so we will take the 10℅, which is in my range of 10-15℅ difference.GTX 1050 Ti can go to ~1900 MHz, while TSMC chips go to ~2100 MHz, right?

As I know, RX 580 is more efficient than RX 480. It can reach same clocks with lower voltage. But AMD and AIB's pushed them to the limit in order to get 5% better performance. Imagine if AMD sells full P10 at 900-950 mV with 4 GB VRAM - it would be better and more efficient than GTX 1060 3GB. Similar to Fury Nano - same perf/watt as GTX 980, even we all know Maxwell is more efficient than GCN (but at much higher price)
So when it comes to the largest chip you have (~600 mm^2), process (clocks) matters since you have no place for improvements. But in lower segments, you can alway make larger chip than competition, especially if you can get better price/mm^2 from foundry
I would assume 56 CUs RX Vega could be sold for $500, if not even less, and be at least in GTX 1080 range
The amount of excuses for Vega at this point over this past year has been unparalleled.
It's time for Raja to go. No longer can we make the excuse that he's just inheriting someone else's problems. Vega is his legacy, and it looks like it's going to cripple RTG for years to come. Enough. Get rid of Raja, get rid of the cheap Chinese design team, and reboot RTG in America where it belongs.
Thread cleaned -- keep the SJW garbage out of this discussion and stay on topic.

They probably had no choice - it had been announced as 1H of the year, it had to come out then or their might have been legal consequences. Tbh if I were AMD right now I'd be focusing on Ryzen, then trying to fight a loosing battle vs Nvidia in high end gpu's. Intel seems to be the easier target.There are no excuses here. imo AMD were better off by not launching Radeon Vega FE now and launching it alongside RX Vega in early August.
No difference in performance between Gaming and Pro drivers.
It is the same story as is with Ryzen. New architecture - software is not ready.

Wasnt the graphics side in Canada (former ATI)?Get rid of Raja, get rid of the cheap Chinese design team, and reboot RTG in America where it belongs.
Did you decide to ignore this?No difference in performance, but the card was running at 1348-1528 in gaming mode, while running at 1650 in pro mode.
then after re-testing it was back to 1650Mhz max
