For less than 2kg, your only choices at the moment are the 14" gaming laptops - the Asus G14 or the Razer Blade 14. Both weighs around 1.7kg, and can use a separate USB-C PD charger if you don't want to carry around the bulky charger for gaming.
Asus G14 only has the Ryzen 9 / RTX3060 (with either FHD or QHD 120Hz), while Blade 14 has three configs available: Ryzen 9 / RTX 3060 with FHD 144Hz or RTX 3070 / 3080 with QHD 165Hz.
Pros and cons of both:
Asus G14:
- More affordable if you opt for the FHD 144Hz (white model), around $2.5k. The grey model with the 1440p display cost at least $3k
- No webcam
- Fingerprint sensor
- Slightly better thermals
- SSD and RAM is upgradable
- Longer battery life (76WHr battery)
Razer Blade 14
- Base model with RTX3060 cost $2.9k from Razer Store. The QHD RTX3070 and RTX3080 prices are through the roof, at $3.5k and $4k respectively
- Superior build quality & minimalist design with RGB lighting. Fingerprint magnet though
- Webcam + IR for Windows Hello
- Very hot thermals
- RAM is soldiered to the motherboard, cannot be upgraded. Stuck with 16GB
- Shorter battery life (61 WHr battery)
- Battery swelling issue is very prominent in the Blade 15 model. Its all over Razer's subreddit, so it might affect Blade 14 down the road
TLDR - Zephyrus G14 for better value for performance, razer blade 14 for best performance and better premium build quality with rgb lighting
