A user reports how his CPU appeared as a bigger model in most hardware identifiers, but it wasn't the reality.
CPU-Z, BIOS, and Even Windows Identified Intel Core Ultra 5 250K Plus as Ultra 7 270K Plus, Despite Showing 18-Core Configuration
A Chiphell user reports that he recently purchased the Intel Core Ultra 5 250K Plus, a new Arrow Lake Refresh SKU that boasts more cores than the 245K. However, when he switched his motherboard from Colorful to GIGABYTE, an unusual behavior was observed. While his CPU box clearly mentions "Core Ultra 5 250K Plus", his CPU kept getting detected as "Core Ultra 7 270K Plus".
The Core Ultra 7 270K Plus is a more powerful SKU, featuring 24 cores and 24 threads, but as you can see in CPU-Z and other monitoring utilities, the SKU was clearly mentioned as having 18 cores. Strangely, none of the utilities showed the actual name for the processor. Popular hardware monitoring software CPU-Z showed it as "Core Ultra 7 270K Plus" even though the core configuration clearly reveals a "6P+12E" arrangement. We don't know if he has the latest CPU-Z version, but if he doesn't, it's for the better, as the software was recently flagged with malware.
Windows 11 also identified it as the 270K Plus. AIDA64 also showed similar results, and even the BIOS couldn't get the CPU name right. It's a strange behavior, particularly when most hardware monitoring utilities can now accurately display the names after the recent updates. The user said that this didn't happen when he was using a motherboard from Colorful, but when he switched to the GIGABYTE B860I AORUS PRO ICE, this happened out of nowhere.
One possible culprit here seems to be the motherboard BIOS. While the user says his motherboard BIOS has been updated to the latest one, it's still not detecting the right name. As per the BIOS release history for the B860I AORUS PRO ICE, the Core Ultra 200S Plus SKUs should already be supported, but it seems there is a bug, which is sending Windows and third-party hardware utilities the wrong SKU name.
