Intel G645 Cpu
Overview
Product sourcing insights & recommendations
The Intel Pentium G645 is a legacy dual-core desktop processor released in September 2012 TechnicalCpubenchmark. Originally launched as a budget "Sandy Bridge" option for office and entry-level home systems, it is now considered obsolete for modern computing needs but retains a niche presence in the second-hand and industrial repair markets.
Product Specifications & Performance
* Architecture: 32nm Sandy Bridge; 2 Cores / 2 Threads at 2.90 GHz TechnicalIntel.
* Efficiency: High power consumption (65W TDP) relative to its low performance, with a modern efficiency rating of just 0.54/100 Cpubenchmark.
* Performance: A PassMark score of ~1,461 puts it roughly on par with the AMD Athlon II X2 270. It struggles with modern tasks, failing to meet minimum requirements for titles like *Fortnite* and modern multi-threaded apps CpubenchmarkOpenbenchmarking.
* Missing Tech: Lacks Hyper-Threading, AVX, and AES-NI, which limits its utility in modern encrypted or highly parallelized workloads Intel.
Market Trends & Insights
* Retail Status: The product has vanished from mainstream retail platforms like Amazon. Current listings typically feature modern alternatives like the AMD Ryzen 5 5600XT or refurbished i5-4590 .
* Sourcing Difficulty: Direct bulk stock for the G645 is scarce on B2B platforms like Alibaba. Suppliers have largely transitioned to the Pentium Gold G6400 or G5400 series for budget desktop builds .
* Pricing: While originally MSRP'd at $80, used units typically trade for under $10–$15 on secondary markets, though some specialized "new-old-stock" listings still attempt higher legacy pricing CpubenchmarkTechnical.
For organizations maintaining legacy LGA1155 infrastructure, specialized CPU distributors like SOUTH LEGEND TECHNOLOGY and Temo Technology offer the best path for bulk sourcing of similar older-generation Intel chips .
The G645 is largely obsolete for retail. Would you like to:
