I7 3940xm Cpu
Overview
Product sourcing insights & recommendations
The Intel Core i7-3940XM is a legacy "Extreme Edition" mobile processor (Ivy Bridge architecture) that currently exists as a high-demand niche product in the secondary and B2B markets. While technically obsolete compared to modern entry-level chips, it remains the "ultimate upgrade" for users maintaining 2012–2013 era laptops like the ThinkPad W530 or Alienware M18x R2.

Product Overview & Performance
- Benchmark Performance: It currently scores an average of 6,015 on PassMark, delivering roughly 24% of the performance of a modern i7-12700H. Cpubenchmark
- Thermal Intensity: With a high 55W–57W TDP, it requires a "Full Thermal Overhaul" (high-conductivity paste and copper shims) to prevent aggressive throttling in most compatible chassis. AlibabaTomshardware
- Compatibility: Strictly requires Socket G2 (rPGA988B) and the SR0US stepping. It is not officially compatible with Windows 11 due to TPM 2.0 requirements. TechpowerupAlibaba
Market Trends & Insights
- Pricing: The market price remains high for its age, currently averaging $344.04 USD on secondary markets due to its "top-of-the-line" status for the G2 socket. Cpubenchmark
- B2B Supply: Verified suppliers in China (e.g., Shenzhen Huateng Technology ) still offer used/refurbished units for bulk or individual purchase, often targeting specialized maintenance or enthusiast segments. Alibaba
- Trend Verdict: For most users, the i7-3840QM is the more logical choice, offering ~92% of the performance with significantly lower thermal risk and cost. AlibabaVersus
