AMD CEO Lisa Su may disclose more details about Zen 3 architecture at CES
On twitter well-known ex-engineer posted a photo of a Taiwanese news-paper, and albeit I cannot read it, it mentions that AMD is to talk about ZEN3 at CES.
That’s said, ZEN3 should be seen as a new architecture is mentioned, which is interesting. We know that ZEN3 is a 7nm+ based product based on the below roadmap slide that was shared a while ago.
Zen1 compared to Zen2 brought a clock-for clock IPC increase of 21%, AMD says it careful, but hints at yet another 15% to IPC increase for ZEN3, that’s again clock for clock and not counting faster clock frequencies. The necessity of more cores has not ended, and the future design path will be based on more cores and a greater compute density as well as a focus on memory bandwidth and I/O connectivity.
AMD qualified the remarks by pointing out that Zen 2 delivered a bigger IPC gain than what's normal for an evolutionary upgrade - AMD has said it's about 15% on average - since it implemented some ideas that AMD originally had for Zen but had to leave on the cutting board. However, he also asserted that Zen 3 will deliver performance gains "right in line with what you would expect from an entirely new architecture."
Despite earlier rumors, AMD also confirmed that ZEN3 and Epyc CPUs will not use a maximum of four threads per core, so you can 'bin' that idea. On the Epyc side, there was news as well, Amazon will be deploying Epyc 2 technology for their server farms and thus web services servers, which is huge for AMD of course. 64-core Rome processors will also be used in Microsoft's Azure service.
Crossfire is no longer a significant focus says AMD CEO Lisa Su - 08/22/2019 05:57 PM
Well, it should not come as a surprise really, SLi and Crossfire are going the way of the dodo. Even with the recent launch, you will have noticed that the Radeon RX 5700 and RX 5700 XT have no suppo...

Intel will inevitably catch up and AMD knows it. I'm not saying Tiger Lake will be better than Zen3 (personally, I doubt it will be) but AMD is basically on a time limit when Intel regains the performance crown. AMD's fanbase is growing and becoming stronger, so, AMD needs to keep the hype train's momentum just like they did back in Athlon 64 days. The more hype there is, the more investors will buy into them. The more money they have to work with, the longer they can delay Intel's succession.

Completely agree with you on this. Intel will inevitably catchup with AMD and there is sort of a 'timer (tic-toc) clock' that Intel has setup for AMD. It can last for one , or maybe even for two more years till they switch sides and Intel takes the lead back again

Perhaps, but I think Intel's focus is elsewhere going forward. Bob Swan, their CEO, made it clear that they want to expand out from CPUs to other products (like GPUs, AI, etc.). They want a bigger slice of the total silicon pie instead of continued dominance of the CPU market.

I wasn't aware of that, but, I can't at all say I'm surprised (and that might explain why Intel hasn't really been putting any effort into x86 for the past 5 years). I'm sure Swan/Intel are aware that the kinds of processors necessary for modern day problems aren't going to be solved on x86.
However, I don't know what kind of processor Intel could produce in a timely manner to offer healthy competition against the following:
Processors ideal for robotics and IoT are dominated by ARM and RISC-V
GPUs are dominated by Nvidia and AMD (Intel's new Xes don't sound all that impressive)
Massively multi-threaded CPUs are dominated by IBM and AMD
Tensor or half-precision float processors are dominated by several companies, but primarily Nvidia and Google
Quantum computers have already been heavily researched by D-Wave, Google, and IBM
There has already been research done with carbon-based transistors using RISC-V
It's not that Intel couldn't compete in any of those markets, but, I don't get the impression they've been making as much progress as their competitors. Or at least I haven't heard that was the case.

*Sigh* Some times i wish AMD keeps their cards close to their chest and surprise us after all they are also giving Intel a heads up by almost a year too. Then again Intel can't really compete with them intill they sort out their 10nm production and bring tigerlake out to their desktops in 2021 but it does set goals for Intel.
