CPU Comparison
Core i5-12400T vs Intel Core i7-11700T
A side-by-side comparison of specs, performance and value. The Intel Core i5-12400T is a 6-core, 12-thread desktop processor from the Alder Lake family, specifically optimized for low-power builds. With a base TDP of just 35W, it is designed for compact, small-form-factor (SFF) PCs and home theater setups where thermals and acoustics are paramount. Despite its low power draw, it reaches boost clocks of up to 4.2 GHz, delivering snappy single-threaded performance. It features 18MB of L3 cache and integrated UHD Graphics 730, handling daily tasks and media playback effortlessly while supporting both DDR4 and DDR5 memory platforms.
The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
Highly responsive for daily applications and moderate multitasking.
Handles office tasks and moderate compilation well, but slows down in sustained all-core workloads.
Gaming
Decent for gaming with a discrete GPU, though limited by lower max boost compared to 65W variants.
The low base clock can cause stuttering in CPU-heavy games unless the turbo is aggressively sustained.
Virtualization
6 cores with 12 threads handle homelab virtualization well.
8 cores are nice, but power limits throttle heavy VM deployments.
Efficiency
Near-perfect efficiency for a desktop chip; runs exceptionally cool.
Outstanding efficiency, drawing minimal power at idle and under load.
