I7 940xm Cpu

The Intel Core i7-940XM Extreme Edition is currently a niche legacy component, primarily sought after for vintage laptop restoration and "ultimate" upgrades for 1st-generation Core-i systems.

Current Market Trends & Pricing

* B2C Retail Pricing: Prices for the i7-940XM vary widely based on seller and condition. Typical listings range from $41.00 to $171.86, with some highly-priced "upgrade kits" reaching near $200 GoogleGoogleGoogle. The 920XM, its slightly slower sibling, is available more affordably between $22.95 and $51.66 GoogleGoogle.

* B2B Supply: Bulk availability is scarce as this is a discontinued product. Some suppliers on B2B platforms offer the 920XM as a low-cost alternative for as little as $1-$3/piece in specialized trade contexts, though standard retail remain higher Alibaba.

* Performance Relevance: While featuring 4 cores and 8 threads, its 45nm architecture is significantly outperformed by modern mobile CPUs. For example, a 4th-gen i5-4258U provides ~34% better single-thread performance despite having fewer cores AskgeekAskgeek.

Critical Technical Insights

* Thermal Bottleneck: The i7-940XM has a massive 55W TDP, making it one of the hottest mobile CPUs ever built. Systems not designed for "Extreme Edition" chips often suffer from severe thermal throttling Tomshardware.

* Compatibility Barriers: It requires a Socket G1 (PGA988) and a mobile PM55/HM55 chipset. Crucially, it has no integrated graphics, meaning it will only work in laptops equipped with a dedicated (discrete) GPU Intel.

* BIOS & Power Support: A BIOS microcode update is often necessary for the system to recognize the 55W power envelope. Additionally, upgrading to this CPU typically requires a higher-wattage power adapter (e.g., 130W+) to handle the increased power draw.
