Lenovo confirms global release for new 15-inch gaming laptop with 48 GB VRAM

[Redaktion]

Lenovo has finally confirmed more details about its first AMD Strix Halo-powered gaming laptop. Launching globally as the Legion 7a 15ASH11, the new laptop will be capable of assigning up to 48 GB VRAM to its powerful GPU too, while surpassing the comparable FA401EA with a 15% larger battery capacity.

[Lets see]

The Strix Halo APU (= RTX 4060 Laptop/Mobile in performance) supports up to 128 GB RAM. Such a waste of APU to offer only 48 GB RAM and, AFAIK, only 75 % of the available RAM can be assigned to a LLM / AI, too. It could be: If it's 64 GB RAM * 0.75 = 48 GB RAM.

Calling it VRAM is ok, but it's not using GDDR6 or GDDR7 chips, but the much slower per bit LPDDR5X at 8000 MT/s on a 256-bit (=quad-channel, and this is AMD Threadripper territory) wide memory bus (256 GB/s = 256-bit * 8000 MT/s / 1000 / 8).

For comparison, a normal dual-channel desktop PC has a ~2.67 slower bandwidth of: 96 GB/s = 128-bit * 6000 MT/s / 1000 / 8.

If it's the full 48 GB VRAM (=64 GB * 0.75), then it's enough for Qwen3.6-35B-A3B-UD-Q4_K_M state of the art AI LLM for agentic workflows; if it's 48 GB * 0.75, then it may not be enough, depending of your workload:

.. I've come to the conclusion that (1) 32768 is the biggest context I can get away with in an adequately smart model, and (2) it just ain't enough.

[Lets see]

Lenovo's laptop will be available with up to 64 GB of LPDDR5X-8000 RAM too, meaning that up to 48 GB VRAM can be assigned to its Radeon 8060S iGPU.

Nevermind, duh!
