CPU Comparison
Intel Core i5-2500 vs Intel Core i5-2500S
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 workloads well, but sustained multi-core loads cause it to throttle below standard i5-2500 speeds.
Gaming
When paired with a contemporary discrete GPU, it could handle 2011-era games well, but is completely bottlenecked for modern titles.
Intel HD 2000 graphics prevent any meaningful modern gaming experience.
Virtualization
Supports VT-x and VT-d, but four threads restrict the number of useful virtual machines.
Good enterprise virtualization feature support, but limited by four total threads.
Efficiency
Consumes up to 95 W under load, which is high by modern efficiency standards.
Excellent efficiency for 2011, drawing significantly less power at idle and light loads than 95 W parts.
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 capabilities
- AVX support exists but lacks AVX2 for modern workloads
- Far too slow for practical AI tasks
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
- Intel HD 2000 is a severe bottleneck for 3D rendering
- Can handle older 2D or very light 3D indie games
- Requires a discrete GPU for any acceptable gaming experience

Our Verdict on Each
A groundbreaking CPU in 2011 that offered incredible IPC gains over its predecessor, but its lack of Hyper-Threading and PCIe 2.0 limitation make it a museum piece today.
Best for: A direct drop-in replacement to repair an older family PC where the original CPU has failed.
Read the full reviewA highly effective power-optimized Sandy Bridge chip that delivered excellent burst performance for its 65 W TDP, though entirely outclassed today.
Best for: Replacing a failed CPU in a proprietary Small Form Factor PC that strictly requires a 65 W or lower processor.
