CPU Comparison
Intel Core i5-2500 vs Intel Core i5-2400
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 legacy Office suites well, but slow for 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.
Bottlenecks modern GPUs heavily, but great for pre-2015 games.
Virtualization
Supports VT-x and VT-d, but four threads restrict the number of useful virtual machines.
Adequate for a basic pfSense router or NAS OS.
Efficiency
Consumes up to 95 W under load, which is high by modern efficiency standards.
Consumes more power per percentage of performance than modern chips.
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 acceleration
- Cannot run modern local LLMs at usable speeds
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
- Paired with a GTX 1060, it can run Skyrim and Fallout 3 excellently
- Will severely bottleneck anything above an RTX 2060
- Single-core speed is too low for modern eSports titles like Valorant
