Ah, I understand where you’re coming from now. You’re really heavily focused on memory transfer speed. That’s really not the only measure of GPU performance and certainly not the one I’m interested in for my workloads. (I do not care for local LLM work for one thing)

For example, the ThinkPad X9 15p with Panther Lake integrated graphics will do 80FPS in Cyberpunk 2077 while the RTX5060 in a Legion 7a will do 109FPS on the same settings (1920x1200, quality up scaling, no frame gen).

So what that means is you can get a super quiet thin and light laptop that gets double digit hours of productivity battery life and has roughly the same tier of gaming experience as a thicker, heavier, power-hungry gaming PC that is pumping 115 watts into the GPU.

To answer your question, LPDDR5x should be more close to 100GB/s so I think you are underestimating the memory bandwidth of Panther Lake laptops. Not sure though.

That all said, overall a RTX5060 or higher laptop would be preferable, I just find it hard to find one that checks a lot of the “thin and light 13-14” premium long battery life productivity laptop that can game on the side” boxes.
