The Case of Rare Laptop SKU: Lenovo Ideapad Gaming 3 15ACH6

 I bought a gaming laptop a month ago (as of writing this blog post). The laptop name is in the title, with these key-selling specs:

  • AMD Ryzen 5 5600H
  • RTX 3060 Laptop (90W)
  • 16GB of DDR-3200 RAM at dual-channel, upgradeable
  • 1920x1080 165Hz display, 100% sRGB
  • 512GB NVMe SSD (which I later upgraded with additional 512GB)

Honestly getting RTX 3060 laptop for cheap (I really mean "cheap", my touchscreen laptop is more expensive) is a blessing. The cooling are also good and I never able to reach 80 degrees Celsius when I use it for gaming (70 is the highest). Now there's just a slight issue: This is a rare SKU.

Why? There are no reviews of this laptop with this GPU. If you look at internet, all reviews of this laptop is the ones with RTX 3050 or 3050 Ti. None of them with 3060. This means there's no way for me to have expectation on the performance and there's no way for me to evaluate the pros and the cons of this variant. I'm on my own.

Lenovo published Product Specifications Reference for this laptop but even some of the information there does not reflect 100% the ones I have. Some of those are:

  • The sheet wrote one of the SSD slots runs at PCIe 3.0x2, but on my unit it runs on 3.0x4 on both slots, checked with Crystal Disk Info.
  • The sheet wrote one of the SSD needs 2242 form-factor (this one is running at 3.0x4), but this is not the case for my unit. They both accepts 2280 form-factor. I mistakenly bought 2242 SSD without knowing because I assume their PSR are correct.

Fortunately I'm relieved to find out that there are many advantages of getting this variant. For example, the RTX 3050 with maximum TGP still beaten by RTX 3060 with lowest TGP and the fact that 3060 Laptop it's almost on-par with the desktop variant (3050, 3070, and 3080 has significant difference). Furthermore the higher VRAM (6GB instead of 3050 4GB) means I can barely run Stable Diffusion locally
