GTC Japan 2015 - Minor Details on NVIDIA's Pascal and Volta Revealed

[HKZeroFive]

PASCAL

Introduced at the end of the keynote, was the future of the GPUs "Pascal" and "Volta". Showing them along with Maxwell, Mr. Hamilton presented the GPU roadmap, displaying the 'world's best double-precision computing power' of Pascal's broadband memory paired with NVLink to show five times of the performance of PCI Express 3.0; unified to achieve the sharing of memory. It was said that the memory is mounted.

Presumably, this mounted memory is what we call HBM2. I'm guessing that NVLink plays a massive part when used with HBM2 memory, but I could be wrong. Using my very basic Japanese, I can translate the four titles in the slide above being (top left to right, then bottom left to right):

-Performance

-Memory Bandwith (probably linked with HBM2)

-NVLINK - High-speed Interconnector

-Unified Memory

Overall, only the features of Pascal were revealed, and didn't reveal or confirm any specifications.

VOLTA

For Volta, Asaumi Takashi of Japan IBM's high-end Systems Division director is on stage. It was revealed to be adopted in two of HPCs of SUMMIT and SIERRA. Both systems are equipped with IBM POWER9 to CPU, that implement NVLink to interconnect. A machine that boasts 40TFLOPs per node performance, and is scheduled to run in 2017.

Again, no real actual specifications (which is fair, since we still haven't got Pascal yet). But it looks like Volta has great capabilities as a workstation/server GPU.

Some people be like: "Should I get a 980ti or wait for volta?"

[Godlygamer23]

NVLink is not an Internet connector.

[givingtnt]

cool. then I guess i ill upgrade to volta when my 780 becomes outdated

also. volta. what a cool name !

[Enderman]

NVLink is not an Internet connector.

lol

he probably meant "internal" connector?

As in inside the PCIe lane?

[Zah]

NVLink is not an Internet connector.

This, that says "Interconnector"

[Juanse]

Well, Nvidia actually names their architectures in honor of the most important physicists

[Zah]

Where's "Edison"?

I know. and I understand the refferences

[Godlygamer23]

Where's "Edison"?

He was not a physicist.

[givingtnt]

Where's "Edison"?

thats fractal design's psu

also not a physicist. actually.

[Juanse]

Where's "Edison"?

Not so much, Tesla, volta and Maxwell were more important,

[Zah]

He was not a physicist.

True, more of a businessman and inventor who made our lives easier than laying groundwork and revolutionary theories.

Without Volta or Maxwell, Edison couldn't have done anything

[HKZeroFive]

NVLink is not an Internet connector.

Ah, that cringy moment when your bad Japanese is just being bad. Fixed it now.

[Zeruel]

Gonna go SLI Pascal. 

[patrickjp93]

Where's "Edison"?

Not an important physicist. Great engineer, but hardly a physicist.

[Megahurt]

One thing to note is that the first graph shows performance / watt, so the performance gain kind of depend on the efficiency gains.

[ACatWithThumbs]

Sadly not really anything new they showed pretty much all of that already:
Example:

the more you look at Edison the more you realize he was kind of a jerk who didnt invent much of anything and had a team of inventors working for him

[Master Disaster]

Not so much, Tesla, volta and Maxwell were more important,

Where's Einstein? Hawkins? Cooper?

[Toddwjp]

the more you look at Edison the more you realize he was kind of a jerk who didnt invent much of anything and had a team of inventors working for him

 

he was still a somewhat talented engineer but he was a much better businessman, yes he didn't invent a tone of things but he was very good at taking things and turning them into a marketable product. a shame by all accounts that he was a bit of a bully in the world of business.

[Rune]

Clearly the reason for Edison not being present is because he is busy at Intel.

[Me1z]

lol

As in inside the PCIe lane?

 

You're close. Its a proprietary replacement for PCIe, or at least that's what was heavily implied by the details leaked last year.
