Can someone explain to little ol me, if HBM2 is meant to be much better than GDDR5, why it even needs 16Gb?
Surely 8Gb HBM2 would be enough.

Afaik badwidth is tied to the number of stacks (stacks and capacity are tied too)! i.e. 2 stacks (8Gb) = 2048bit; 4 stacks (16Gb) 4096bit

No 4 stacks can be as much as 32GB for HBM2, tis' 64GB for HBM3 ~ https://www.techpowerup.com/225244/third-generation-hbm-could-enable-graphics-cards-with-64gb-memory

Triggered.

Capacity is not bandwidth. 27 yodaflops wouldnt matter if you only have 128MB of VRAM.

8GB HBM holds as much as 8GB GDDR.

So HBM2 is max of 8Gb/stack, that does not take from the fact that you still need 4 stacks to achieve 1TB/s of bandwidth. This means that Vega 10 will most likely max out at 512Gb/s. So 16Gb vega will be full chip and full memory stacks while 8Gb vega will have one HBM2 stack disabled and run at 256Gb/s?

With HBM2 bandwidth and capacity is kinda correlated.

Yes as far as my research into past reviews is concerned, Battlefield 3 is the only game you currently test that shows an overclocked GTX 1070 beating a stock GTX 1080. The only one. Never mind most people will be playing a modern game at 1440P or 4K on a 1070/1080, where the gap widens considerably between the two cards. Maybe it's time to update the OC test game...

The OC 1070 benches he posted are at 1440p

danbert2000 · May 16, 2017

Quoted OC gain is 13% (I'll round up to be nice), let's compare The Witcher 3 at 1440p:

64.2 * 1.13 = 72.5
Lower than a "stock" 1080, much lower than the MSI GTX 1080 Gaming at stock.

Again, 34.2 * 1.13 = 38.6

Raevenlord said "the GTX 1070's performance can easily be overclocked to reach a stock 1080," but even at 2100 MHz and maxed out memory, which is the very top end of a 1070 overclock, the 1070 falls short. And that's assuming that these games would scale as well as Battlefield 3 does with the overclock. Not likely.

Can the 1070 approach a stock 1080 when max overclocked with a prime chip and memory? Yes. Can "the GTX 1070's performance... easily be overclocked to reach a stock 1080"? Not by any objective reading. Raevenlord is trying to make this a 970/980 situation. It's not. If he took out the "easily" qualifier and explained his methodology I'd be fine with that. Until then, it's just a half-truth.

You've misunderstood. The original dispute was whether a 1070 could be overclocked to reach a stock 1080. The benches you posted are for the overclocked out of the box card but that card can still be overclocked further.

Actually, you've misunderstood. If you read the text under the graphs, I do the math assuming perfect scaling on all games at 13% past the "out-of-the-box" overclock. And then I go on to point out that there's nothing easy about overclocking a 1070 to 2100 MHz and then still falling short on those games.

Same here, i got myself a GTX 1070 but had driver problems, card just wont recognize my 120hz HD TV (stuck at 60 hz which my HD 7970 had zero issues) , had to return it back. Now i am waiting for Vega

If you're on Windows 10, that's a Windows issue (Xbox DVR/Vsync forced on by W10, especially for Nvidia Optimus/systems with both integrated & dedicated graphics). I fixed this same issue on a friend's rig and is one of the many reasons I refuse to downgrade to Windows 10, in addition to the privacy concerns & forced updates.

Also you may want to uninstall the AMD card with DDU before upgrading. I upgraded from one Nvidia card to another and had some issues until I did this (and make sure you remove any overclocking software fully before uninstalling).
