CPU Comparison
Intel Core i5-2400 vs Core i7-2600
A side-by-side comparison of specs, performance and value. The Intel Core i5-2400 served as the baseline standard-power quad-core processor for the Sandy Bridge generation. Operating at a 95W TDP, it removed the power constraints of the 'S' series, allowing for a higher 3.1 GHz base clock and a 3.4 GHz turbo boost. Like other non-K i5s of its era, it operates without Hyper-Threading, strictly limiting it to four concurrent threads. It features the full 6 MB L3 cache and Intel HD 2000 integrated graphics. This chip was the quintessential mainstream desktop CPU of early 2011, offering a significant leap in IPC (Instructions Per Clock) over the previous Lynnfield architecture.
The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
Handles legacy Office suites well, but slow for modern web apps.
Still usable for basic office tasks and web browsing.
Gaming
Bottlenecks modern GPUs heavily, but great for pre-2015 games.
Can still run older games, but bottlenecks modern GPUs.
Virtualization
Adequate for a basic pfSense router or NAS OS.
Handles light VMs well.
Efficiency
Consumes more power per percentage of performance than modern chips.
95W TDP on 32nm is not efficient by modern standards.
Specialized Performance
AI / ML
- No AI acceleration
- Cannot run modern local LLMs at usable speeds
- No AI hardware
- Too slow for modern AI
Content Creation
Gaming
