So all the vram is on the GPU die. And they manage to cool it. You'd have to be super-rich to make this in your shed. Dam, and there's not very many high-end gamer's.

to me seems a good clocker
Thos are some pretty damn good numbers and seeing my post right above quoted, far exceeded my expectations.

HBM2 is typically "on-die". And the power delivery system is important to know about. Green or Red, if you are using modded BIOS or hard mods, you want to know it's not going to fail.

Pretty good numbers until you factor in the $700 price point for ~1080Ti performace (barring a select few titles with CSAA).

Better late then never /shrug

All we can hope for is that Navi will dominate in the sub 500 dollar price point in Q4 of this year. With that have hopes that the high end in 2020 will match whatever nVidia puts out.

Bold for emphasis. That is not accurate. The HBM stacks are very close to the GPU die, but they are not the same thing. The four HBM2 stacks on the Radeon VII and the GPU itself are on the same interposer.

Vega 20 takes most of the existing Vega 10 GPU and shrinks it to 331 mm², down from 495 mm² for Vega 10. By shrinking the die in this way, AMD made room on Vega 20's underlying silicon interposer to add on two more stacks of HBM2 RAM.

Didn't feel like looking up interposer. Thanks for the info. Used quotes around on-die since I figured I was using the wrong term, but most call the whole package the die and would know what I meant.

Only reason I have the 2080Ti's is because of step-up. Otherwise the price is steep. I also hope AMD comes with something to force nvidia to drop prices.

I haven't seen any evidence of that and I sure hope not. At most you can call the interposer a package, just like with AMD's Threadripper PCB and Intel's Core 2 Quads before that.

without pretty validation I would not consider that too much (like claiming v64 at 1800ish cough cough) but, beside a photoshop rework, hitting 2000 on a amd gpu would not be bad at all, I'll take just that from the post, anyway we will see as soon as a VII will drop on oc.net\hwupgrade.it in right hands

My Vega 64 at 1800Mhz isn't fake lol It's a bug I found when flashing back from the 8GB FE bios. I also want to add I purchased a Radeon VII. So one will be in the right hands.
