Seems like a pretty responsible way to handle the problem: found, stopped from spreading, fixed, shipments resumed, and fix sent to owners of parts already shipped.

It also seems like Intel would receive at least some negative press if they released more details that people could speculate on. While I would prefer to know more, I can understand that there may be reasons why Intel would not want to share more information.

Usually the details on stuff like this don't get publicized until the products are EOL and they release full documentation unless there's some sort of exploit that can hit it.

The most surprising part of this to me is as bit_user commented on the original article that it's impacting the MCC not the XCC CPUs.

On a complete tangent I'm still hoping they drop prices on the MCC die Xeon X SKUs. Not that the platform is affordable at all, but if the CPUs (at least the 12/16c) were closer in price to their desktop counterparts I think the market would open up more.

I wouldn't be surprised if the test engineers at the factory kept this from shipping. There aren't a lot of these parts made and the next batch might be a month or more away. They might have wanted a few days to test their fix with a reasonable number of parts in order to make sure the fix really works.

Yeah, because (for anyone who doesn't know) the XCC version is the multi-die one and therefore presumably much more complex.

I gave up my last hopes of them being remotely affordable, when it came out that they would use the same physical socket as the XCC version.

That's okay, though. Since mainstream CPUs reversed the trend of cutting down on PCIe lanes, and now that they're available with up to 32 threads, I don't really need a full-fledged workstation anyhow.

the MCC design is used for chips up to 32 cores, which are the source of high-volume sales for Intel, while the XCC variants are used for the halo chips between 36 and 60 cores.
That's funny. I'd have assumed the XCC is where most of their volume lies. Since hyperscalers seem to care about density as much as anything else, I'd guess they want the one with more cores and accelerators.

Me too, but I was hoping the 2455X would be around $800. I'd still much rather have a proper PCIe lane setup with the extra memory bandwidth (without super clocking the DDR5 though it seems pretty much all 13th gen can do 7200 without much trouble). My current system has been in use since 2016 and the one it replaced was from 2008. For my desktop usage I could go with a regular desktop setup now and probably be okay with it though I would have to buy a new 10gb card. The HEDT platforms just had more longevity built into them so I'd rather go that route if it wasn't for the cost being basically double now.

The machine I use for 24/7 operation wouldn't have worked with a regular desktop setup if I wasn't going TrueNAS instead of Windows this time. Not enough lanes for full NAND SSD performance, but there were for P1600x drives. As it was I still had to go buy some bifurcation cards since Intel client platforms (including W690) can't do anything other than x8 splits.
