If it's 7+nm it will be big. It's not unexpected to me. If so, the successor to Turing will be next Spring and announced at GTC 2020. Wider discussion on the Nvidia sub-reddit:

Tom Petersen left Nvidia - likely for Intel. I saw it coming.

Would love to see intel in the gaming graphics market, especially at the high end. 
 
I won't be very interested in computer gaming with high end launches in the $1000-$1200 range, like most other people. 

I just saw yesterday that Samsung tvs have Freesync automatically with Xbox One X, and presumably it's successor.

Bigger tv (I have 65" now) with Freesync with a small device I can use to stream all my other media is a pretty compelling. I watch more tv then I game, and I could see giving up higher AA and some better shadows in the trade.


RE: Ampere Taped Out? Tom Petersen leaves Nvidia for Intel. - apoppin - 04-04-2019

Well, now you can use FreeSync with Nvidia cards. Some "unapproved" displays work well. Others don't.

https://www.techspot.com/article/1779-freesync-and-nvidia-geforce/

RTX 2080s are below $800 now and they are generally all faster than GTX 1080 Tis. And you can buy a RTX 2080 Ti Black Edition for $999 directly from EVGA. The next gen on 7nm next year will be cheaper and faster now that RTX has been introduced.


RE: Ampere Taped Out? Tom Petersen leaves Nvidia for Intel. - CyberMage - 04-05-2019

Yeah...but....

GTX980 launch price- $549

GTX1080 launch price -$599 ($699 FE)

GTX2080 is $800 ….8 months after launch, and basically offering 1080Ti performance that everyone has had for two years, that they paid $700 for then.



And the $999 Turing "deal" is basically the new Titan. I'd bet that sometime this fall there will be a "miracle $699 2080Ti level" launch to mop up the most people who didn't pay the gouger prices.

Have you noticed that prices are going up on *everything*?

A "miracle" $699 2080 Ti performance level launch would require a faster $1200 'Titan' RTX to also be launched, wouldn't it? I certainly see this happening next year at 7nm but am not sure it will happen this Autumn.

Wow, Ampere already. Tech has become much less exciting to me lately. It appears that we are limited by the laws of physics. CPU, GPU, and smartphone APU development has really slowed down from what I am used to seeing. We need some type of manufacturing technological breakthrough to really improve things, or else quantum computing. We'll see what happens. I haven't been overly impressed by the 7nm node based on what I have seen thus far. We're still waiting for Zen 2 also, which I was hoping to hear something about by now.

7nm for smartphones is a read dud. It won't be for graphics cards and CPUs. Expect a Zen 2 announcement (so it is rumored) at Computex. Also probably something about Navi.

I think ray tracing is the most exciting thing to hit PC graphics in at least a decade. It's in its infancy now but it holds great promise. Eventually, it will make its way to VR.

And you can test it out yourself on a GTX 1080 Ti with the very latest driver. Look for a new review to be posted afternoon tomorrow here with links to 3 impressive (forward looking) demos that feature VR as well as the performance data for each of the Pascal (and Turing) cards using the 3 ray-traced games (Metro Exodus/SotTR/BFV).

There is speculation that nVidia Ampere could be revealed at the GTC coming up this month.

There is also talk of "Big Navi" from AMD which is purportedly 30% faster than an RTX 2080 Ti. That sounds like some kind of crazy insane rumour to me that's just so wild that I would say it's completely crazy. Ampere at the GTC sounds more credible though. It's been about 2 years since Turing was launched.

I won't be going to the GTC 2020 .... no one else will. It has been canceled and will be an online event only.

Quote:NVIDIA has decided to shift GTC 2020 on March 22-26 to an online event due to growing concern over the coronavirus.

This decision to move the event online instead of at the San Jose Convention Center reflects our top priority: the health and safety of our employees, our partners and our customers.

NVIDIA founder and CEO Jensen Huang will still deliver a keynote address, which will be available exclusively by livestream. We’re working to schedule that and will share details once they’re available.

That said, I expect the successor to Volta to be announced by Jensen, probably on March 23. Usually Nvidia launches Tesla first, followed by Quadro and then by GeForce. However, they may surprise us this year.

As to Big Navi being significantly faster than RTX 2080 Ti ... remember RTG's "poor Volta" before Vega launched? We simply don't know what to expect from AMD.
Beee

Here's what you can expect over the next couple of years from AMD as gleaned from their Financial Analyst Day earlier today.
https://www.hardwaretimes.com/amd-rdna-2-with-h-w-level-ray-tracing-support-vrs-and-50-more-perf-per-watt-coming-later-in-2020/
Quote:AMD’s Financial Analyst Press Conference just got underway and we have learned a little more about team Radeon’s plans for this year. For starters, no there was no explicit mention of Big Navi (at least not yet). Secondly, yes RDNA 2 graphics cards will come later this year with ray-tracing support, Variable Rate Shading and a performance-per-watt improvement of nearly 50% (same as GCN to RDNA 1).


And a reddit user made a nice list
https://www.reddit.com/r/Amd/comments/fe2k9n/info_from_amd_financial_analyst_day/
Quote:Fun fact: Rome doubled Performance compared to "competitors"

Zen 3 in 2020 confirmed (though only Milan specifically mentioned)

Zen 4 in 5nm until 2022

AMD CDNA as new compute gpu architecture

Higher focus on CPU/GPU interconnect

"Extend Chiplets in 2.5D stack design

Plan to do "Advanced X3D" stacking

(For investors: Financial Model increased dramatically, ~20% CAGR)

~200.000.000 (200 Million) Zen 2 Cores shipped (250 Mil across all Zen Cores)

"X3D" means chiplets + HBM

3rd gen Infinity Arch for 8 GPUs coherently connected

Unify CPU & GPU memory as one coherent region with higher bandwidth than PCIe 4

"Moore's Law pace in relentless pursuit of compute efficiency gains"

Samsung Graphics IP Licensed AMD's technology huh

Earlier slide mentioned ~20% perf gain GCN vs RDNA (IIRC) and now slide mentions 50% perf gain

RDNA 2 Hardware-Based Ray Tracing + VRS "and more" confirmed

RDNA 3 on "Advanced Node" (5nm as well?)

RDNA 2 in 2020 confirmed

RDNA 2 with 50% perf gain over RDNA

MS DXR 1.1 implemented in RDNA 2 and co-developed with AMD

CDNA in 2020 on 7nm optimized for ML/HPC with interconnect between GPUs

CDNA 2 3rd gen Infinity Arch for CPU and GPU interconnect (used in El Capitan most likely?)

Will continue to focus on ROCm and HIP (yes yes, me like this)

ROCm officially supported by TensorFlow and lots of frameworks, continued updates to list of supported frameworks thorough 2020

More APUs and PRO systems should be available in 2020

Zen 3 APUs until 2021

"Optimized drivers that worked flawless" oof

"Big Navi" confirmed as they target 4k (5700 targetted 1440p)

New consoles coming "Holiday 2020" (Christmas?)
