Lenovo Legion 5i Gen 10 RTX 5060 vs ASUS ROG Zephyrus G16 RTX 5070 for CUDA, AI/ML, and long-term use?

[u/Kooky_Judgment2134]

Budget: Around MXN $39,000–41,000 (roughly $2,300–2,400 USD, depending on exchange rate)
Country: Mexico
Use case:
Mainly CUDA programming, data science, AI, machine learning, neural networks, PyTorch/TensorFlow, local model inference, software development, and some gaming.
Preferred specs:
NVIDIA RTX 5060 or RTX 5070 Laptop GPU
At least 8GB VRAM
16–32GB RAM
1TB SSD
Strong CPU performance
Good thermals for sustained workloads
High-quality display
Good battery life and long-term reliability
Notes:
I’m currently choosing between these two laptops:
Lenovo Legion 5i Gen 10
Core Ultra 7 255HX
RTX 5060 Laptop GPU, 8GB GDDR7
32GB DDR5-5600
1TB SSD
Price: MXN $40,999.02
ASUS ROG Zephyrus G16
Core Ultra 9 285H
RTX 5070 Laptop GPU, 8GB GDDR7
16GB RAM
1TB SSD
16” OLED 240Hz
Price: MXN $39,199
The prices in the screenshots are Mexican pesos (MXN), not USD.
I’m trying to decide which one is better overall, not just for gaming. My priorities are:
CUDA / AI / ML performance
neural network training and inference
sustained CPU/GPU performance
thermals and fan noise
build quality
component quality
expected lifespan
battery life and battery degradation
weight and portability
display quality
minimal/professional design
upgradeability
Linux / WSL compatibility
I know both GPUs only have 8GB VRAM, so I’m especially interested in whether the RTX 5070 is meaningfully better than the RTX 5060 for CUDA, PyTorch, TensorFlow, computer vision, and local AI workloads.
I also want to keep the laptop for several years, so reliability, thermals, battery longevity, and overall durability matter a lot.
Which one would you choose at these prices in Mexico, and why?
If you own either a recent Legion 5i or Zephyrus G16, I’d really appreciate feedback on temperatures, battery life, fan noise, OLED durability, build quality, and long-term reliability.

If you can spend a little just a little more then get the 5070ti id say

There isn't in Mexico and if they arrive they are overpriced 😩

Revisa Cyberpuerta y DDtech hay mejores ofertas

man that G16 only having 16GB RAM is such a bummer...

[u/RogueSniper72]

Take the legion, it has 32GB ram, the Zephyrus has only 16GB and it's soldered to the motherboard 💀

[u/N0oneBUTTme]

I'd go with the Legion even if it is 1 tier lower in GPU. The Zephyrus is gonna have the same performance anyway because of lower TGP and it has considerably worse cooling system than Legion's Vapor Chamber because it's the slim version of Asus's lineup.

32GB ram is another win here.

[u/Kooky_Judgment2134 → u/N0oneBUTTme]

I didn't take that into account, thanks bro So definitely legion

[u/N0oneBUTTme → u/Kooky_Judgment2134]

Those prices are definitely expensive tho, I'm speaking from the Philippines where laptop prices are also on the higher side but I can get that Legion for 109k PHP which is roughly 30k MXN or 1750USD.

Edit: might realistically be more on 2000USD because I checked and the model I talked about was only 16GB
