CPU Comparison
Intel Core i5-2400S vs Core i7-2600S
A side-by-side comparison of specs, performance and value. The Intel Core i5-2400S is a quad-core processor tailored for small form factor desktops that cannot accommodate standard 95W cooling solutions. By maintaining four physical cores but lowering the base and turbo frequencies compared to the standard i5-2400, Intel achieved a 65W thermal envelope. It lacks Hyper-Threading, a defining characteristic of non-K Sandy Bridge i5 processors, meaning it handles four threads natively. Equipped with 6 MB of shared L3 cache and Intel HD 2000 graphics, it provided a balanced blend of multi-core productivity and low-power operation for home and office PCs during its prime.
The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
Handles basic office tasks but struggles with heavy spreadsheets or modern web apps.
Still handles basic office tasks and web browsing.
Gaming
Cannot handle modern AAA games, even at lowest settings.
HD 2000 is too weak for modern games; needs a discrete GPU.
Virtualization
Can run a basic NAS OS or light VM, but limited by 4 threads.
Can run light VMs but limited by 65W power profile.
Efficiency
Good power-to-core ratio for the 32nm era.
65W TDP was excellent for 2011, but 32nm is outdated now.
Specialized Performance
AI / ML
- No AI hardware capabilities
- Too slow for practical machine learning inference
- No AI hardware
- Too slow for modern AI workloads
Content Creation
Gaming
- 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
- HD 2000 is very weak
- PCIe 2.0 limits modern GPUs
- Okay for retro gaming with a GPU
