FAQ

What's the most important specification for business laptops?

For business use, prioritize in this order:

  1. RAM (16GB minimum, dual-channel)
  2. SSD speed (PCIe 4.0 NVMe)
  3. Display quality (IPS, 300+ nits)
  4. CPU (Core Ultra 5/7 or Ryzen AI 5/7)

How do I know if specifications are upgradeable?

Ask your OEM specifically:

  • RAM: "Is memory soldered or SO-DIMM socketed?"
  • Storage: "How many M.2 slots? What sizes?"
  • Wi-Fi: "Is the wireless card M.2 or soldered?"

What specifications affect battery life most?

In order of impact:

  1. Display brightness and resolution (higher = more power)
  2. CPU TDP class (H > U > V)
  3. Discrete GPU (significant drain even idle)
  4. SSD type (NVMe uses more than SATA)
  5. RAM amount (minimal impact)

Should I prioritize CPU or GPU for general business use?

CPU. Integrated graphics (Intel Iris Xe, AMD Radeon 780M) handle:

  • Office applications
  • Video conferencing
  • 4K video playback
  • Light photo editing

Only specify discrete GPU for:

  • Video editing
  • 3D modeling
  • Gaming
  • Machine learning
