The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
Snappy for light tasks, but 4 threads limit heavy productivity workloads.
Strong performance for office suites and general multitasking.
Gaming
Good burst performance for older games, but low base clock hinders sustained heavy gaming.
Not suitable for gaming due to weak HD 630 graphics.
Virtualization
Can run a light VM, but resources are quickly exhausted.
Limited by 4 cores and 4 threads, poor for heavy VMs.
Efficiency
Excellent performance-per-watt, typical of Intel's T-series bins.
Excellent performance per watt for silent desktop builds.

Our Verdict on Each
The i5-6600T offers slightly more headroom than the 6500T within the same 35W limit, making it a slightly better choice for SFF refurbishing, though still outdated overall.
Best for: If you are picking up a used 1-liter PC (like a Lenovo ThinkCentre Tiny or HP EliteDesk Mini) for a home server, HTPC, or basic office terminal, the i5-6600T is a great little workhorse. It offers a nice balance between the lower clocks of the 6500T and the higher power draw of the 65W parts. It runs incredibly cool and is virtually silent. However, buying this chip standalone to build a new PC is a terrible idea. Modern budget processors deliver vastly superior performance and efficiency. If you have this CPU, an SSD and 16GB of RAM will make it feel incredibly responsive for daily tasks, but do not expect it to handle modern gaming or heavy creative workloads.

Best for: Building a low-power, silent NAS or HTPC using used parts.
