Intel's Xeon Sapphire Rapids CPU series has had a bumpy ride so far, with the discovery of bugs resulting in delays pushing proceedings back by more than two years. Units have been shipping out for the past couple of months, but Team Blue ran into more issues in late June—a subset of fourth Generation Intel Xeon Medium Core Count Processors (SPR-MCC) could interrupt normal system operation under certain conditions. Intel confirmed to Tom's Hardware that they were actively investigating the latest bugs, and had paused shipment of affected MCC die-based models (featuring up to 32 cores).

The publication has very recently received an update from their contact at Intel. A company spokesperson stated: "Last week, we informed you (Tom's Hardware) of an issue on a subset of 4th Generation Intel Xeon Medium Core Count Processors (SPR-MCC) that could interrupt system operation under certain conditions. Out of an abundance of caution, we temporarily paused some SPR-MCC shipments while we thoroughly evaluated a firmware mitigation. We are now confident the firmware mitigation addresses the issue. We have resumed shipping all versions of SPR-MCC and are working with customers to deploy the firmware as needed." Specifics about the latest mitigations efforts have not been divulged, but Intel is confident that these fixes will not impact processor performance.
