Performance Compared

Productivity

Intel Core i3-12100TE62

Adequate for office tasks and light multitasking. The reduced base clock means sustained workloads run slower than the standard i3-12100.

Core i5-12400TBest82

Highly responsive for daily applications and moderate multitasking.

Gaming

Intel Core i3-12100TE30

The UHD 730 can handle very light e-sports titles at 720p low settings. For any serious gaming, a discrete GPU is mandatory.

Core i5-12400TBest75

Decent for gaming with a discrete GPU, though limited by lower max boost compared to 65W variants.

Virtualization

Intel Core i3-12100TE45

4 cores and 8 threads can handle a couple of lightweight VMs, but the 35W TDP limits simultaneous heavy workloads.

Core i5-12400TBest72

6 cores with 12 threads handle homelab virtualization well.

Efficiency

Intel Core i3-12100TE78

Good efficiency for an Alder Lake part, delivering reasonable performance per watt at the 35W power level.

Core i5-12400TBest98

Near-perfect efficiency for a desktop chip; runs exceptionally cool.
