Local ChatGPT 3.5 Performance: ASUS TUF Gaming A16 (RTX 4070) vs RTX 5090 Laptops
ASUS TUF Gaming A16 (2023–2024)
GPU: RTX 4070 Laptop
CPU: AMD Ryzen 9 or Intel Core i9
Typical Price: £1200–£1450
Performance: ~17–29 TFLOPS
Storage: 4TB Crucial P3 NVMe SSD (Upgradeable to 8TB)
Notes: Great value, rugged build, strong thermals, upgradeable design
RTX 5090 Laptop (2025)
Models vary, but typically paired with Intel Core Ultra 9 or Ryzen 9 8955HX
Typical Price: £2200–£2800
Performance: ~31–45 TFLOPS
Storage: Often includes 2TB–4TB NVMe SSDs, upgradeable
Notes: Top-tier, AI-ready, future-proof, premium cooling and display
What You’re Paying For in 2025
GPU Leap: RTX 5090 offers up to 50% more raw compute power than the 4070, with DLSS 4, better ray tracing, and AI acceleration.
CPU Pairings: Often bundled with Intel Core Ultra 9 or Ryzen 9 8955HX, pushing performance even further.
Display Upgrades: Many 5090 models feature MiniLED or OLED panels, 240–300Hz refresh rates, and 4K support.
Cooling & Build: Premium thermals, vapor chamber cooling, and ultra-rugged chassis — ideal for sustained heavy workloads.
