Lenovo releases 18-inch gaming laptop globally with more powerful processor and 192 GB RAM

[Redaktion]

One of Lenovo's most powerful gaming laptops has relaunched with a more powerful processor option. Still available with the GeForce RTX 5080 or GeForce RTX 5090, the Legion 9 18IAX10 now comes with the Intel Core Ultra 290HX Plus to complement its 240 Hz display and up to 192 GB of DDR5 RAM.

Simply rounds from $6k plus tax to $10k if you are impatient to get a 192GiB DDR5 and ...5090 gets 24 GiB GDDR7. I hope they toss in a few hands of 18" matte glass screen protectors, or thicker hydrogel ones.

[192 GB+24 GB VRAM is nice]

5090 gets 24 GiB GDDR7

It's a "5090 Laptop" / "5090 Mobile", using GB203 chips (256-bit memory bus width, 896 GB/s), but is using 3 GB per memory chip, instead of 2 GB, like on the 5070 Ti / 5080 desktop cards.
See en.wikipedia.org/wiki/Blackwell_(microarchitecture)#Blackwell_dies.

256-bit/32-bit per chip = 8 chips:
5070 Ti / 5080 desktop: 8 chips * 2 GB per chip = 16 GB VRAM.
5090 Laptop: 8 chips * 3 GB per chip = 24 GB VRAM.

512-bit/32-bit per chip = 16 chips:
5090 desktop: 16 chips * 2 GB per chip = 32 GB VRAM.
Now imagine: 16 chips * 3 GB per chip = 48 GB VRAM, but that would eat into their RTX PRO workstation cards.

For $6k one could get an actual 5090 desktop (512-bit memory bus width, 1792 GB/s) PC and a 5090 desktop also has 32 GB of VRAM, not 24.

192 GB RAM +24 GB VRAM can fit full DeekSeek-V4-Flash AI (huggingface.co/unsloth/DeepSeek-V4-Flash-GGUF) weights and still have plenty of memory left for the context.

Other big 300B AI LLM models quants that also fit into 192 GB RAM + 24 GB VRAM, and where 128 GB RAM are not enough (although dense Qwen3.6-27B stands out in performance and doesn't require a lot of memory, but it being 27B active parameters, putting (a quant) on a GPU's much faster VRAM, not system's RAM, is recommended, so it runs faster):

(the current DeekSeek-V4-Flash is a preview version and the final version is supposed so be released this month)

llama.cpp (that many GUI tools use as backend and are just wrappers, but llama.cpp has its own nice webUI) DeepSeek V4 support is coming along:
