User Purchases Intel Core Ultra 5 250K Plus, But CPU-Z and Windows Recognize It as Core Ultra 7 270K Plus

A case has emerged involving a user’s Intel CPU, which mistakenly appeared under a more powerful model name in multiple hardware identification tools.

Misidentification of Intel Core Ultra Models in Software

A user from Chiphell recently shared an intriguing experience after acquiring the Intel Core Ultra 5 250K Plus, part of Intel’s new Arrow Lake Refresh lineup. The new CPU, which offers an increase in core count over the prior 245K model, has raised questions about identification accuracy. After transitioning his motherboard from Colorful to GIGABYTE, the user encountered an unexpected issue: his CPU was consistently labeled as the “Core Ultra 7 270K Plus, ”despite being correctly boxed as the 250K Plus.

The Core Ultra 7 270K Plus is known for its enhanced performance capabilities, boasting 24 cores and 24 threads. However, monitoring tools like CPU-Z reported the CPU’s core configuration incorrectly as an “18-core”setup. Notably, the software did not reflect the correct CPU designation. Although it displayed the 270K Plus label, the actual architecture consists of a “6P+12E”core arrangement. Users are uncertain whether this misidentifier arose from an outdated version of CPU-Z, which has been scrutinized recently for potential malware threats.

Interestingly, this misidentification was consistent across other platforms, including Windows 11 and AIDA64, with the BIOS also failing to display the correct CPU name. Such anomalies are surprising, particularly since recent updates to hardware utilities typically ensure accurate recognition. The user noted that the problem only surfaced after the switch to the GIGABYTE B860I AORUS PRO ICE motherboard; with the previous Colorful motherboard, the CPU’s identity was accurately presented.

The persistent miscommunication regarding the CPU name might be linked to the motherboard’s BIOS. Although the user verified that his BIOS was updated to the latest version, the discrepancy in identification continues. According to the B860I AORUS PRO ICE’s BIOS release history, support for the Core Ultra 200S Plus WeU is implemented; however, it appears that a bug is causing Windows and other hardware detection tools to misread the CPU designation.
