Future Ice Lake to get PCIe 4.0?

Above claimed to be seen listed in PCI-SIG. So some future Ice Lake CPUs are looking like they'll get PCIe 4.0. The mobile CPUs released around a year ago didn't have it. There are no signs of mainstream desktop Ice Lake happening. So that leaves the server Ice Lake CPUs due towards the end of the year as the most likely candidate for getting this upgrade. It'll also help Intel not fall so far behind Epyc.

 

I suppose we can't rule out a mobile refresh but I think this is unlikely as it has less to gain from such an upgrade, and would make more sense to be rolled into the next gen CPU.

They will, this is why most Z490 motherboards actually use PCIe 4.0 switches, to ensure future 4.0 compatibility

I'll believe it when I see it somewhere that isn't a twitter image of some unknown table. It doesn't sound implausible, but it seems like it would be a big change to make without a new generation of chips. Although given Intel has basically been on the same generation for the last 5 years who knows at this point.

¯\_(ツ)_/¯

I don't think this is big for the consumer platform 

I mean dmi 4 and pcie 4.0 in general doesn't bring a whole lot to the table 

What would be interesting is socket 3647 getting a refresh of some kind with pcie 4.0 that would be cool

Well 11th gen Rocket Lake is pretty much confirmed to feature PCI-E 4.0 compatibility, hence why all Z490 boards as far as I'm aware use 4.0 switches.

Maybe they'll do an Ice Lake refresh with added 4.0 support, but I don't really see its use in mobile machines at the moment.

The rumour there is that Comet Lake's successor, Rocket Lake, will support PCIe 4.0, so mobo support needs to be built in now. But neither of those are Ice Lake.

It is wise to treat any rumour with caution, and I did try to poke around the PCI-SIG site myself to see if I can find it, but I guess it's behind a paywall. Unlike more open SIGs like USB or Bluetooth.

 

Ice Lake server is essentially a new CPU compared to Ice Lake mobile. For an earlier parallel, look at Skylake-SP and Skylake-X compared to the original desktop Skylake-S. While the execution cores themselves might be more or less unchanged in function, the blocks around it certainly were not left alone and we had the addition of AVX-512 units, and a totally different L3 cache structure.

 

Further, Ice Lake is the first generally available CPU from them that is not Skylake derived. Using the Sunny Cove architecture, it bought with it a big boost in IPC compared to Skylake.

I know, on the other hand when in the recent years has Intel supported three CPU generations on one socket? ;) There's a good chance Z490 will be EoL after Ice Lake if we go by recent trends

Am I misunderstanding something here? On the Z490 platform (socket 1200) we currently have the recently launched 10th gen CPUs, which are Comet Lake. The replacement to that, what would be 11th gen, is Rocket Lake. So this new socket will get one more CPU generation next year. Ice Lake doesn't enter the picture.

Honestly I stopped keeping up with Intel's naming scheme after ice lake 

10th gen just has too many names 

Tiger lake 

Comet lake 

Ice lake 

It's stupid and I hate it

That's in part why I prefer to use the architecture names. You know exactly which product you're talking about then. AMD are just as bad. I have to say Zen 2 when talking about latest CPUs, because I can't even say Ryzen 3000 as it has older architectures in that number system.

 

Within the limits of my last response, it was clear we were talking about mainstream desktop CPUs so you can ignore all the mobile ones.

No, it's me that got confused over all of the newest and upcoming Intel-Lakes... Forget what I said, apologies!
