CPU Comparison
Intel Core i5-14400T vs Intel Core Ultra 5 225T
A side-by-side comparison of specs, performance and value. The Intel Core i5-14400T is a power-efficient desktop processor featuring a hybrid 6 P-core and 4 E-core architecture for a total of 10 cores and 16 threads. With a remarkably low 35W base power rating, it is tailored for small form factor PCs, thin clients, and home theater setups where thermals and acoustics are critical. The processor runs at a 1.5 GHz P-core base frequency but can boost up to 4.5 GHz when needed, providing burst performance for demanding tasks. It includes 20 MB of L3 cache and Intel UHD Graphics 730, capable of handling 4K media playback effortlessly. Supporting both DDR4 and DDR5 memory on the LGA 1700 socket, the i5-14400T offers an excellent balance of everyday computing capability and power-sipping efficiency for eco-conscious users.
The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
Hybrid cores handle office and light productivity very well.
Handles office and development workloads well, but sustained multi-core tasks run slower due to power constraints.
Gaming
Good for 1080p gaming when paired with a discrete GPU.
Adequate for gaming when paired with a discrete GPU, but the 35W PL1 may cause lower 1% lows in CPU-bound scenarios compared to the standard 225.
Virtualization
E-cores provide good background VM support.
10 threads are usable for light VM workloads, but power limits make it less ideal for running multiple VMs simultaneously.
Efficiency
Outstanding performance per watt at 35W.
Excellent efficiency at base power, though the PL2 turbo window means actual power draw varies significantly under load.
