CPU Comparison
Intel Core i5-2500 vs Intel Core i5-2400S
A side-by-side comparison of specs, performance and value. The Intel Core i5-2500 is the standard 95 W quad-core desktop processor from the Sandy Bridge generation, featuring a 3.3 GHz base clock, 3.7 GHz turbo, and 6 MB of L3 cache for mainstream desktop computing.
The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
Adequate for legacy office suites, but modern web browsers and productivity apps will feel sluggish.
Handles basic office tasks but struggles with heavy spreadsheets or modern web apps.
Gaming
When paired with a contemporary discrete GPU, it could handle 2011-era games well, but is completely bottlenecked for modern titles.
Cannot handle modern AAA games, even at lowest settings.
Virtualization
Supports VT-x and VT-d, but four threads restrict the number of useful virtual machines.
Can run a basic NAS OS or light VM, but limited by 4 threads.
Efficiency
Consumes up to 95 W under load, which is high by modern efficiency standards.
Good power-to-core ratio for the 32nm era.
Specialized Performance
AI / ML
- No AI acceleration hardware
- Lacks modern vector instruction extensions
- Fundamentally incapable of running modern AI models in a practical timeframe
- No AI hardware capabilities
- Too slow for practical machine learning inference
Content Creation
Gaming
- The CPU itself can still feed older GPUs adequately
- Modern games will be severely CPU-limited
- PCIe 2.0 may cause minor bottlenecks with modern high-end GPUs
- HD 2000 graphics lack driver support for modern titles
- Even with a discrete GPU, CPU bottlenecks severely
- Playable only in legacy esports like CS 1.6
