So there was a rumor last year there might be a dual socket Threadripper/EPYC mobo, and that the CPU's would be capable of it, but now that I search for it, it seems that it only was 'some guy on Reddit says' style rumor. Despite that, anyone knows if there is any chance for that?

#12Am I missing something here or is Intel starting to lag behind on Fab Tech? I thought they were years and billions ahead?!?
The most likely cause of Intel's lagging is a wall of cost/benefit to being both designer and fab. This hit AMD earlier by being smaller(and arguably, with a different management style, AMD could have held on to their fabs longer) but each node only gets more expensive and harder to keep busy with orders which in turn means a greater need for external customers to fund R&D. Intel had a reprieve of almost a decade wit…
Intel's biggest mistake over the past 10 years was not to open it's foundry services sooner now it's custom foundry services are nearly irrelevant outside of a few niche markets.
Mobile SoC design and being answerable to a huge number of very large customers forced fabs to evolve their processes in a way where market forces and customer demand forces requirements rather than office politics.
Intel has still an edge on many parts of the manufacturing process but as far as the lithography goes they've lost this round.
Luckily for them their 10nm was much more ambitious than any of the 7nm designs and they are facing problems that other fabs will not face until their 5nm and beyond processes.
Intel is also fighting a much tougher fight now TSMC was always good (better than AMD/GloFo) but now you also have the Alliance which is IBM/Samsung/GloFo which combine resources on process R&D.
GloFo botched their 20/22nm process and had to scrap it completely and if they couldn't use Samsung's 20nm process and call it 14nm AMD's Zen would likely would never have materialized because of the WSA.
And this is essentially the gist of things GloFo/Samsung/IBM are essentially a united front, TSMC is as capable as ever and what all of these 4 (and more) share in common is that they answer to external customers so if something doesn't work there is a much bigger pressure to drop it and find something that would instead of sinking more and more cost into it because of internal politics.

#13I'm really curious if AMD can overtake Intel in single threaded performance. They already have the lead in number of cores (per socket) and multi threaded benchmarks like cinebench (when using same number of cores and clocks). At the moment Intel has a slight edge in IPC and quite a bit better clocks. If they can close the IPC gap or even overtake Intel and GlobalFoundries 7nm process really can clock around 5ghz thi…
To my knowledge the achievable IPC gains for a single thread are limited. Therefore it can be assumed that other players catch up in figures of IPC while the market leader kind of gets stuck with only a tiny advantage.

But there are mobos for dual socket epyc... https://www.amazon.com/Supermicro-H11DSI-NT-Dual-sockets-Mot...

#15Earlier quoted context omitted.
I think the IPC gap will become an interesting battle in the near future, especially as gains that came from aggressive speculation have proven to introduce security holes (take your pick of Meltdown, Spectre variant n ,...).
Are there any good post-Meltdown benchmarks conparing Intel and AMD?
Anandtech did a benchmark but that had a flaw in the way they measured the time. Many other benchmarks are with unpatched OS versions to keep comparability. It's not easy to judge when they don't explicitly investigate that effect.

Yes, Intel has fallen behind already. Their 10nm process node and a supposed equivalent to TSMC, GloFo, and Samsung's 7nm nodes, won't be ready for mass production until 2019. Meanwhile all the other foundries will have their 7nm nodes ready for mass production this year.
Also, it's rumored that Intel's 10nm will actually be worse for clock speeds than its 14nm is.

Intel has already given a reason for the lagging: trying to improve density by 2.7x instead of 2.4x.
Other foundries were able to improve density by 2.7x for their 7nm nodes compared to their 14/16nm nodes, so I'm not sure what exactly Intel is doing there.

Phoronix is my go to for those in depth benchmarks with security patches

I keep wondering if there are some gains left by dropping the x86 legacy baggage e.g. using RISC-V or ARM64. It seems that there should be some loss due to x86 weirdness and past compromises
