Ranked #2 in Best Laptops For Machine Learning
Asus ROG Strix Scar 18
9 sources

The Asus ROG Strix Scar 18 delivers desktop-class performance through its Intel Core Ultra 9 processor and NVIDIA GeForce RTX 5090 GPU, supported by an advanced liquid metal cooling system. Ultrabookreview found that the 18-inch Nebula HDR Mini-LED display offers stunning visual fidelity with over 2,000 dimming zones, though enabling ELMB technology introduces PWM flicker for sensitive users. However, the device is extremely heavy at approximately 3.7kg and suffers from significantly limited battery life during gaming, typically lasting only one to two hours. Additionally, the integrated 720p webcam feels like an afterthought on such a flagship machine. This laptop fits enthusiasts seeking maximum stationary power who can accommodate its bulk, while those needing portability or all-day unplugged use should look elsewhere.

Strengths
  • — Equipped with top-tier Intel Core Ultra 9 processors and NVIDIA GeForce RTX 5090 GPUs, delivering desktop-class performance for gaming and content creation.
  • — Features a stunning 18-inch Nebula HDR Mini-LED display available in up to 4K resolution at 240Hz with over 2,000 dimming zones.
  • — Includes an advanced cooling system with liquid metal thermal compound that sustains high performance under heavy loads.
Watch-outs
  • — Extremely heavy at approximately 3.7kg (8 lbs) and thick, making it impractical for frequent portability.
  • — Battery life is significantly limited during gaming or intensive tasks, typically lasting only one to two hours.
  • — The webcam resolution is low (720p), which reviewers consider an afterthought on a flagship device.

Razer Blade 16 with RTX 5090
Ranked #3 in Best Laptops For Machine Learning
Razer Blade 16 with RTX 5090
10 sources

The Razer Blade 16 delivers top-tier gaming performance via the Nvidia GeForce RTX 5090 mobile GPU housed in an exceptionally thin, premium CNC-milled aluminum chassis. Ultrabookreview found that while the build quality is dense and stylish, the device suffers from noticeable flex in the keyboard deck and lid compared to past generations. The glossy OLED display offers stunning contrast and high brightness but lacks an anti-reflective coating, causing significant mirror-like reflections in bright environments. Additionally, a column of non-standard macro keys disrupts muscle memory and leads to frequent accidental presses during typing. This laptop fits users who prioritize portability and premium aesthetics over raw thermal efficiency or ergonomic comfort. Buyers seeking better value, superior battery life for all-day use, or a glare-free screen should look elsewhere.

Strengths
  • — Features a premium CNC-milled aluminum chassis that is exceptionally thin (14.9mm) and lightweight for its class at approximately 2.1kg.
  • — Equipped with a high-end OLED display offering QHD+ resolution, 240Hz refresh rate, and up to 1,100 nits peak brightness in HDR modes.
  • — Includes an extensive port selection such as Thunderbolt 5, HDMI 2.1, USB-A ports, and a UHS-II SD card reader despite the slim profile.
Watch-outs
  • — The glossy OLED screen lacks anti-reflective coating, causing significant mirror-like reflections in bright environments.
  • — Includes a column of non-standard macro keys that disrupts muscle memory and leads to accidental key presses.
