Performance Compared

Productivity

Intel Core i5-14400TBest80

Hybrid cores handle office and light productivity very well.

Intel Core Ultra 5 225T75

Handles office and development workloads well, but sustained multi-core tasks run slower due to power constraints.

Gaming

Intel Core i5-14400T70

Good for 1080p gaming when paired with a discrete GPU.

Intel Core Ultra 5 225T70

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

Intel Core i5-14400TBest75

E-cores provide good background VM support.

Intel Core Ultra 5 225T65

10 threads are usable for light VM workloads, but power limits make it less ideal for running multiple VMs simultaneously.

Efficiency

Intel Core i5-14400TBest95

Outstanding performance per watt at 35W.

Intel Core Ultra 5 225T80

Excellent efficiency at base power, though the PL2 turbo window means actual power draw varies significantly under load.
