Intel’s Sapphire Rapids Xeon CPU Production Crisis Launches in early 2023

Intel’s Sapphire Rapids Xeon CPU have seen one heavy delay And there are many reasons why this happened. From our good friend, Igor Vlosek Igor’s labThere’s a detailed outline of what went wrong and when the chips will actually be available.

Vulnerabilities in Intel Sapphire Rapids Xeon CPU bugs, production woes, countless reasons for 2023 delays

The Intel Sapphire Rapids Xeon CPU lineup for servers was intended to launch and compete with AMD’s EPYC matching CPUs. Since their announcement, AMD has launched the Milan, Milan-X, and will launch Genoa in the coming months, While we were hoping that Sapphire Rapids might ship around the same time as Genoa, that doesn’t appear to be the case as the launch is being pushed back to early 2023.

With a total of 12 (!) steps, they haven’t covered themselves with glory at all, and I can’t remember any project so far that required so many steps before you could get used to it somewhat. It started with A0 and A1, then progressed through B0, C0, C1, C2, D0, E0, E2, E3 and E4 to the current E5! The market launch was planned around 1.5 years ago and the plan was updated again recently.

Until now, Intel customers and partners had assumed the chips would be available in the second half of 2022, but internal information is now getting a little more concrete. Intel has now announced a “launch window” for Sapphire Rapids (SPR) for calendar weeks 6 to 9 (February 6, 2023 to March 3, 2023), while the first shipments to selected recipients are still in two waves by 2022. is set for. The forecast is for calendar week 42 for the smaller model (2S) and calendar week 45 for the larger model (4 and 8S).

According to Igor, at the moment, Intel has a total of 12 steppings for its Sapphire Rapids Xeon CPUs. A0, A1, B0, C0, C1, C2, D0, E0, E2, E3, E4, and the latest E5 are stepping. The main reason for taking so many steps is that the production of Sapphire Rapids has not been phenomenal and along the way, Intel faced various problems.

One of these problems is a security vulnerability that was exposed in the previous chip iteration. While this is a new step on Intel’s way, some Intel customers were reluctant to wait and order the affected chips, but they were not going to use the affected part of the CPU, so they would be unaffected by the vulnerability. There is also talk of Intel shipping the low-end SKUs first, while higher-volume supplies are expected to ship later.

According to Igor’s lab, according to internal documents, the latest Intel Sapphire Rapids Xeon CPU launch is slated for weeks 6 to 9 of 2023. It is between February 6, 2023 and March 3, 2023.

Yes. And giving a little more detail on Neelam, we are already ramping up several SKUs of Neelam Rapids. They began to ramp up last quarter. So we have a lot of those ramps.

The particular issue we highlighted was not affecting those SKUs, so they keep on ramping up. So we did another tape out, which I would say, for larger volume SKUs, and they will be volume shipping in the second half of the year. So you’ll see that we’re building them up and launching them. So we’re completely on track for that, and we feel like we’re having all of the issues that we’re having in getting that product to market.

So we feel very comfortable with that. We’re working very closely then — the emerald sapphire goes into the stage. That’s why we are working closely with our customers on there time. The product looks very healthy.

So we are well on track. So that would be a ’23 product. And then there’s the Granite and Sierra One ’24 product. And just to remind everyone, this is a major new platform.

We’ve seen some too soon Performance Numbers for Sapphire Rapids Xeon CPU And things don’t look great for Intel as they miss out on competing against Milan. While the chiplet CPU design allows for higher ASP, the impending delay means that there are clearly going to be some major consequences and unfavorable consequences for pushback. Intel has also shed light on its next generation Emerald Rapids CPU which they expect to launch by 2023 and Granite Rapids Chips However, given the current delay till 2024, we cannot rely heavily on the figures.
