CPU Comparison
Intel Core i5-650 vs Intel Core i5-660
A side-by-side comparison of specs, performance and value. The Intel Core i5-650 is a dual-core desktop processor from the Clarkdale generation, featuring Hyper-Threading and integrated Intel HD Graphics, launched in early 2010.
The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
Extremely slow by modern standards for any productivity application.
Slightly faster than the i5-650 but still fundamentally inadequate for modern workloads.
Gaming
Cannot run modern games at playable frame rates. Only suitable for pre-2010 titles.
Cannot run any modern game at acceptable frame rates.
Virtualization
Two cores with Hyper-Threading offer minimal utility for virtualization.
Two cores with Hyper-Threading provide minimal virtualization capability.
Efficiency
73W TDP for two cores is poor efficiency compared to modern chips.
73W for a dual-core processor is inefficient by modern standards.
Specialized Performance
AI / ML
- No AI acceleration instructions
- Far too slow for any ML workload
- No AI acceleration
- Far too slow for any machine learning workload
Content Creation
Gaming
- No modern game will run acceptably
- Integrated HD Graphics cannot handle 3D workloads
- Only viable for 2D or browser-based games
- Dual-core limitation makes most modern games unplayable
- HD Graphics 733MHz cannot handle any 3D rendering
- Was barely adequate for 2010-era gaming with a discrete GPU
