A side-by-side comparison of specs, performance and value. The Intel Core i3-10105T is a 4-core, 8-thread low-power desktop processor utilizing the 14nm Comet Lake-R architecture with a 35 W TDP, designed for compact desktops and small-form-factor builds.
The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
Handles basic office tasks fine, but heavy spreadsheets or multitasking will feel slower than standard 65 W chips.
Good for everyday office tasks. The 28-second PL2 window helps with bursty workloads, but long-running tasks are hampered by the low base clock.
Gaming
The low 3.0 GHz base clock and 3.9 GHz turbo severely limit gaming performance, even with a dedicated GPU.
The CPU can handle budget gaming when paired with a discrete GPU, but the reduced base clock means lower 1% low frame rates compared to the standard i3-12100 in CPU-bound scenarios.
Virtualization
4 threads can manage one lightweight VM, but the low power limit restricts performance.
Can run 2-3 lightweight VMs, but 4 cores at 35W limits the practical number of concurrent heavy workloads.
Efficiency
Good efficiency for the 35 W power class, though the 14nm process is less efficient than modern 10nm alternatives.
Strong performance per watt for desktop use. The 35W TDP results in very low electricity costs for always-on systems.

If power isn't strictly constrained, a Ryzen 5 5600 offers dramatically better multi-threaded performance at a competitive price.
Our Verdict on Each
The i3-10105T offers adequate performance for basic tasks in a 35 W envelope, but its low clocks, DDR4-2666 limit, and PCIe 3.0 make it hard to recommend over modern low-power alternatives.
Best for: The i3-10105T should only be considered if you are repairing an existing SFF (Small Form Factor) office PC that requires a 35 W processor to match the chassis cooling capabilities. Its $134 launch price was difficult to justify even in 2021, as the standard i3-10100 cost less while offering significantly higher clock speeds. If you are building a new low-power system today, you should look toward 12th or 13th-gen 'T' variants which offer dramatically better performance per watt on a newer architecture. Avoid this chip for any new build, especially since it lacks modern features like PCIe 4.0 or DDR5 support.
Read the full reviewA solid choice for SFF and low-noise desktop builds that balances the excellent Alder Lake single-core IPC with a modest 35W power envelope, though the standard i3-12100 offers notably better sustained performance for minimal additional power draw.
Best for: Building a small form factor PC, home theater PC, or always-on media server where low power consumption and quiet operation are priorities.
