CPU Comparison
Intel Core i5-3439Y vs Intel Core i5-3365M
A side-by-side comparison of specs, performance and value. The Intel Core i5-3439Y is an ultra-low-voltage dual-core mobile processor from the Ivy Bridge Y-series, running at just 13 W TDP with a 1.5 GHz base clock and 2.3 GHz turbo, designed for tablets, convertibles, and fanless ultrathin devices.
The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
Only suitable for the most basic document editing and simple tasks; struggles with modern web applications.
Can handle basic office tasks but struggles with modern web applications and multitasking.
Gaming
No integrated graphics capability listed; even if present, performance would be negligible for any gaming.
Only suitable for very old or lightweight games at low resolutions and settings.
Virtualization
With only two threads and no Hyper-Threading, virtualization is extremely limited.
Supports VT-x and VT-d, but only two cores limit practical virtual machine usage.
Efficiency
Impressive power efficiency for 2013, but modern low-power chips deliver vastly more performance per watt.
Reasonable for a 2012 35 W mobile chip, but far less efficient than modern processors.
Specialized Performance
AI / ML
- No AI acceleration capabilities
- Insufficient compute performance for any AI workload
