That is the confusing part. I thought reviews mentioned it as lower clocked but toms shows 1.8Ghz on the FE but a huge discussion ensued upon its release that based upon the chance that the FE was indeed not clocked the same as the RX speculating the RX would be for gaming and the FE lower for greater stability.Is this the 1.6 Gbps HBM2?
You missed the important Effective Texture Bandwidth, one you show relates to cache.I'm going to go ahead and re-post the three B3D Suite tests that show bandwidth issues with Vega:
Tom just report the official spec which was meant to be 1.8Gbps, but its performance does seem closer to 1.6Gbps spec and yeah debate is whether this is due to the part/issues whatever they are for now/mixture of both.That is the confusing part.

Interesting to note buildzoid registered significantly lower than stock power draw while at 1800 mhz LN2, suggests leakage is a major issue for Vega, I wouldn't have been too surprised to find it drawing same power as stock but 100W less as he claimed is just nuts
For Hynix I read they have no HBM2 that AMD is using yet.Tom just report the official spec which was meant to be 1.8Gbps, but its performance does seem closer to 1.6Gbps spec and yeah debate is whether this is due to the part/issues whatever they are for now/mixture of both.
But then we do not know if the 8-Hi is from Samsung or SK Hynix last I could tell from reports in July, where only Samsung had officially mentioned they are now production ready for 8-Hi.
You raise a valid point earlier that this may not reflect performance for consumer part which is 4-stack, but we need more confirmation by testing when it launches although I agree logically one would expect the 4-Hi to perform better, but there are quite a few reasons performance can be done for Vega FE in certain tests.

Yeah I tend to think it is Samsung but I got a lot of bitching suggesting that on another tech forum that SK Hynix has no 8-Hi and was pulling back on forecasted spec *shrug*.For Hynix I read they have no HBM2 that AMD is using yet.
I saw it hereYeah I tend to think it is Samsung but I got a lot of bitching suggesting that on another tech forum that SK Hynix has no 8-Hi and was pulling back on forecasted spec *shrug*.
So probably at best AMD with RX Vega will manage half the BW of the V100 that is 4-stack Samsung HBM2 and that gives 450GB/s - not mentioning as competition just to give a real world figure if using Samsung HBM2 with RX Vega.
That would still be higher than the 408 GB/s Vega FE hits with one of the effective BW tests of B3d if taking same behaviour to be happening for consumer GPU as well.

One of the key takeaways from this, besides the expected higher prices of GDDR6 and HBM2 memory from SK Hynix, is the fact that this confirms that the company has not started mass production of HBM2 quite yet. For the time being then, this leaves Samsung as the only HBM2 manufacturer shipping in volume, which means I wouldn't be surprised if we see the company's 4-Hi HBM2 stacks show up on AMD's forthcoming HBM2-based RX Vega video cards.
I think you do but I'll ask, do you like the Omen? It caught my eye tbh.
But definitely works better with AMD freesync at 75hz than with Nvidia at 60hz. (It frame skips with Nvidia cards at 75hz, ). But it is buttery smooth at 48-75hz with AMD freesync.
Cant tell you how tired I am looking at AMDs sites Facebook twitter and such just to make sure I don't miss the release dates and what outlets will have them. I don't do Facebook (have a page visited once in last 4 years) No way in hell ever having a twitter account. So this is quite annoying having to visit these just so I can get a damn Vega GPU.
Dual GPU?

Somebody please think of the children.
Crazy thought: the rumoured 70MH/s is done on the 600W dual Vega.
Considering the Vega FE does about 35MH/s, I'm a lot more likely to be right than wrong.
Well, I was planning on the 56, and on the fence for water cooling, so we will see...
I do. Trust me, I mean checking everywhere.Not sure why you need to keep track of AMD from there instead of just looking at the front page of this site.
Gamer Nexus joins the mining rumor train, says they "independently" confirmed with their sources in industry that RX Vega will be around 70 for mining. (Hes not sure if 56 or 64). I've linked the video to timestamp.
Could be but, generally dual GPU cards come out quite a bit later than the default cards.
AMD's demo of the Radeon Pro SSG was stuttering in front of our eyes, with the AMD representative saying that the Radeon Pro SSG was an early prototype board - understandable. But then he added that the 2TB SSD needs to have its cache cleared "every hour or so" as it "fills up". Hmm, OK - weird... why not just clear it and show us 8K editing in real-time, as the sign next to AMD's system said. Then on top of that, AMD said that the drivers weren't polished yet, another reason for the stuttering and no real-time 8K video playback at 24FPS. AMD's demo was dropping into the 14-15FPS mark, and given those excuses... NVIDIA's graphics prowess is a testament to their hardware handling next-gen 8K video editing. NVIDIA's current-gen Quadro P6000 is available right here, right now, and handles 8K video editing and playback in real-time.
Update: I've talked to AMD about this article since it went live, and I've been informed that something isn't right here - and that the new Radeon Pro SSG will wipe the floor with NVIDIA's Quadro P6000 graphics card. AMD has promised to send me a Radeon Pro SSG when it launches to do my own in-house testing against the P6000 with real-time 8K video editing, something that is meant to be only capable on Radeon Pro SSG.
juanrga the 70 was referring to hash rate, the "if 56 or 64" was referring to the Vega model
I would never buy a dual GPU setup from AMD again until they show commitment to improving dual GPU compatibility. I've run multiple GPU setups many times from NVIDIA and AMD and SLI has always worked better in terms of compatibility. And these days, it's getting worse for both camps, not better. I don't see a dual GPU Radeon card being worth it vs a Titan Xp.
Ironic, considering GPU PhysX is dead.I wouldn't call Multi GPU tech dead. It's just bad in its current form, which I believe everyone agrees on. There is much to be desired with SLI/CF configurations, but the micro stutter and sometimes non existent/bad scaling really puts many off. I personally know someone who went from 2x1080s to a single 1080Ti and he said he will never recommend SLI ever again in its current form. He now uses one of those 1080s as a dedicated PhysX card and he sold of the other one.
