CPU Comparison
Intel Core i5-4690T vs Intel Core i5-6500T
A side-by-side comparison of specs, performance and value. The Intel Core i5-4690T represents the ultra-low-power tier of the Haswell Refresh lineup, engineered specifically for compact, thermally constrained environments. With a remarkably low 45W TDP, this quad-core processor drastically cuts power consumption compared to standard desktop parts.
The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
Sufficient for basic office and web tasks, but sustained multi-threaded workloads will quickly hit the 45W power limit, causing clocks to drop.
Adequate for office tasks but slow for rendering or heavy multitasking.
Gaming
The low base clock of 2.5 GHz hurts minimum frame rates in CPU-heavy games. It is suitable only for very light or older 2D/esports titles.
Low base and boost clocks severely limit gaming performance compared to 65W parts.
Virtualization
VT-d and vPro are great for lightweight VMs, but the aggressive power limiting and 4 threads restrict running multiple concurrent instances.
4 threads and low clocks make it poorly suited for VMs.
Efficiency
Excellent efficiency for its era. The 45W TDP ensures very low idle and load power consumption, perfect for always-on devices.
Excellent performance-per-watt for a 14nm quad-core of its era.
Specialized Performance
AI / ML
- No AI hardware
- Power limits severely throttle any vector processing
- Not applicable for AI workloads
- Insufficient thread count and low clocks make AI inference impractical
Content Creation
Gaming
- 2.5 GHz base clock results in low minimum FPS
- 45W power limit restricts sustained multi-core turbo
- HD 4600 graphics are insufficient for modern gaming
- Only suitable for retro or extremely light game titles
- Low clock speeds cause sub-60fps frame rates in CPU-heavy titles
- Not recommended for gaming without a GPU
- Suffers from severe 1% low frame drops

Our Verdict on Each
The i5-4690T is an efficient quad-core squeezed into a 45W envelope. While it sacrifices base clock speed heavily to achieve this, it remains a reliable choice for specific embedded or OEM applications where heat is the primary enemy.
Best for: Replacing a failed CPU in an older OEM mini PC, AIO system, or digital signage player bound to the LGA 1150 platform.
Read the full reviewA capable low-power option in 2015, the i5-6500T sacrifices clock speeds for efficiency, making it strictly a budget/SFF salvage part today.
Best for: If you are buying a refurbished SFF office PC (like an HP EliteDesk or Dell OptiPlex) for basic home server duties, web browsing, or as a thin client, the i5-6500T is perfectly adequate. It runs incredibly cool and quiet, making it great for a living room PC that only handles 1080p streaming. However, you should never buy this processor standalone to build a new PC. Its low clocks and locked multiplier severely limit its potential, and modern low-power alternatives offer significantly better performance-per-watt. If you already own it, max out the RAM and add an NVMe SSD to extract the best possible everyday responsiveness, but do not invest in a dedicated GPU expecting a great gaming experience.
