CPU Comparison
Intel Core i5-650 vs Intel Core i5-680
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.
Best single-threaded performance in Clarkdale but still insufficient for modern productivity.
Gaming
Cannot run modern games at playable frame rates. Only suitable for pre-2010 titles.
High clock speed helps slightly but the dual-core design remains a fundamental barrier.
Virtualization
Two cores with Hyper-Threading offer minimal utility for virtualization.
Two cores with Hyper-Threading remain inadequate.
Efficiency
73W TDP for two cores is poor efficiency compared to modern chips.
73W for 3.6GHz on 32nm was reasonable for 2010 but poor by modern standards.
Specialized Performance
AI / ML
- No AI acceleration instructions
- Far too slow for any ML workload
- No AI acceleration
- Unsuitable for any ML 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
- 3.6GHz clock cannot compensate for two cores in modern games
- 733MHz HD Graphics far too weak for 3D rendering
- Even with a discrete GPU in 2010, quad-cores were preferable
