SK Hynix HBM2 and GDDR6 Specs and Availibity
Memory manufacturer SK Hynix updated its product stack with the new information on their HBM2 and GDDR6 memories. They offered High-Bandwidth-Memory 2 starting Q3 2016 to Q2 2017.
It seems from the published date that volume availability of HBM2 memory was pushed back starting at third quarter of 2016, back to Q1 2017 six months later. This indeed is a strong indicator as to why AMD RX Vega has been delayed by this much. That launch is highly dependant on HBM2 availability.
HBM2
In it's latest product sheets Hynix states that HBM2 became available this quarter. This data was spotted by videocardz btw. If Radeon RX Vega will feature HBM2 from SK Hynix then you can expect 410 GB/s with two on-die memory stacks (which the 8GB models will have).
| High-Bandwidth-Memory 2 | ||||
|---|---|---|---|---|
| Databook | Density | Bandwidth | Speed | Avaibilitity |
| Q3 2016 | 4GB | 256 GB/s | 2.0 Gbps | Q3 2016 |
| Q3 2016 | 4GB | 204 GB/s | 1.6 Gbps | Q3 2016 |
| Q4 2016 | 4GB | 256 GB/s | 2.0 Gbps | TBD |
| Q1 2017 | 4GB | 204.8 Gb/s | 1.6 Gbps | Q1 2017 |
| Q2 2017 | 4GB | 204.8 Gb/s | 1.6 Gbps | Q2 2017 |
GDDR6
SK Hynix is now also listing GDDR6 memory to be available in the fourth quarter already. We recently discussed the potential of this more easy to implement memory type already. The product mao shows two types to be fabbed in the initial design phase, both will be based on 8Gb OCs each this offering 1GB per chip. There are differences in memory frequency, the faster type will be able to reach 14 Gbps, the slower one is roughly 12 Gbps. This means that at best we should get 672 GB/s bandwidth with 384-bit bus or 448 GB/s with the 256-bit bus. As comparison the absolute fastest GeForce GTX 1080 (Ti) with new type memory runs 11 Gbps.

It's not only you, but HBM does have very tangible real bandwidth and latency advantages. It's no luck that NVIDIA is using it wherever they need real performance (see the Tesla cards).

Is it only me or does HBM2 look like it wont be the magic thing giving AMD any meaningful edge against NVidia? The next NVidia cards (soon^tm) probably have like 12Gb GDDR6, which will offer more capacity at faster speeds than HBM2 for Vega? Not that I knew anything about graphics cards memory in detail...
