CPU Comparison
Intel Core i5-3230M vs Intel Core i5-3337U
A side-by-side comparison of specs, performance and value. The Intel Core i5-3230M (PGA variant, SR0WY) is a dual-core, quad-thread Ivy Bridge mobile processor in a socketed FC-PGA12F package for Intel Socket G2 (988B), offering 2.6 GHz base and 3.2 GHz turbo clocks with Intel HD 4000 graphics and the rare advantage of being upgradeable.
The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
Adequate for basic office tasks but overwhelmed by modern web applications and multitasking demands.
Struggles with heavy web apps but okay for basic text.
Gaming
HD 4000 graphics provide minimal gaming capability, limited to very old titles at low settings.
Completely unsuited for modern gaming.
Virtualization
VT-x and VT-d support is present, but two cores limit practical virtual machine usage.
Low clock speed and 2 cores make VMs painful.
Efficiency
Standard 35 W mobile power consumption, unremarkable by modern efficiency standards.
17W TDP was excellent in 2013, but outdated now.
Specialized Performance
AI / ML
- No AI acceleration hardware
- No AVX2 or later instruction support
- Completely unsuitable for AI workloads
- No AI hardware
- Extremely slow CPU inference
Content Creation
Gaming
- HD 4000 with 1100 MHz turbo is the limiting factor
- Playable in very old or lightweight games only
- The socketed nature means a discrete GPU upgrade path may exist in some laptop chassis
- HD 4000 is too weak
- Low TDP limits sustained performance

Our Verdict on Each
The PGA variant of the i5-3230M is functionally identical to its BGA sibling in performance but offers the significant advantage of being socketed and replaceable. This made it popular in business laptops where field upgradeability was valued.
Best for: Upgrading an existing Socket G2 laptop from an older Sandy Bridge processor to extend its useful life.
