Frontend developers want fast build times and instant Hot Module Replacement (HMR). You might think your code is the problem. Often, the problem is your laptop power settings.

Two laptops with the same Intel Core Ultra 7 155H chip can perform differently. One builds Vite projects fast. The other runs slow and gets hot. This happens because of TDP, PBP, and MTP.

Vite uses ESBuild to process modules. This process needs consistent CPU power.

The difference in hardware types:

  • Ultrabooks have low PBP (9-28W). They save battery.
  • Gaming laptops have high MTP (up to 115W). They focus on speed.

How this affects your work:

Build Speed High MTP laptops let the CPU run at max speed for longer. This makes production builds much faster.

HMR Performance HMR needs instant responses. If your PBP is below 15W to save battery, you will notice lag when you change code.

RAM and Heat Running React or Vue projects requires steady resources. 16GB of RAM helps maintain stability.

However, low power chips face thermal throttling. The CPU slows down to stop overheating. This happens after 5 to 10 minutes of continuous work.

Production builds are heavy tasks. High MTP machines with good cooling keep high performance. Thin ultrabooks often heat up quickly. They slow down the build process to protect the hardware.

Your hardware power limits dictate how fast Vite feels.
