CPU Comparison
Core i7-6785R vs Intel Core i3-10105T
A side-by-side comparison of specs, performance and value. The Intel Core i7-6785R is a specialized desktop processor launched in May 2016 as part of the Skylake-R family. Built on a BGA package, it is soldered directly to the motherboard and primarily intended for All-in-One (AIO) systems, NUCs, and mini PCs. This 14nm quad-core CPU features Hyper-Threading, processing 8 threads simultaneously. It operates at a base clock of 3.3 GHz and boosts up to 3.9 GHz. Its standout feature is the inclusion of Intel Iris Pro Graphics 580, which features 128MB of embedded DRAM (eDRAM), offering significantly better graphics performance than standard Intel HD Graphics. With a 65W TDP, it balances capable processing with powerful integrated graphics. It supports dual-channel DDR4-2133 or DDR3L memory. The i7-6785R is a niche product, ideal for compact systems requiring strong graphical output without the space or power for a discrete GPU, though its BGA nature limits upgradability.
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.
Gaming
The low 3.0 GHz base clock and 3.9 GHz turbo severely limit gaming performance, even with a dedicated GPU.
Virtualization
4 threads can manage one lightweight VM, but the low power limit restricts performance.
Efficiency
Good efficiency for the 35 W power class, though the 14nm process is less efficient than modern 10nm alternatives.

Our Verdict on Each
A unique BGA desktop CPU with exceptional integrated graphics for its era. Perfect for small form factor builds where a discrete GPU isn't possible.
Best for: Buying a used NUC or AIO with this chip pre-installed
Read the full reviewThe 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.
