Intel x Nvidia Serpent Lake leaks as Strix Halo rival with capable CPU and big GeForce RTX Rubin iGPU

[Redaktion]

Intel and Nvidia are officially developing x86 chips for future Windows laptops. Intel Serpent Lake architecture could be a result of this partnership. RedGamingTech claims that Intel could use an Nvidia RTX iGPU for the Serpent Lake APUs.

16X LPDDR6 would be a big deal, actually moving things forward.

16 memory channels for increased bandwidth.

DDR6 has 24-bit per channel? (as opposed to DDR5's 64-bit per channel) -> 16 channels * 24-bit = 384-bit. AMD's Strix Halo has a 256-bit wide memory interface and supports up to 128 GB RAM. Assuming same memory density and scaling up linearly, this INTEL + NVIDIA APU can have 192 GB, which would be pretty good.

Strix Halo: 8000 MT/s * 256-bit / 1000 / 8 = 256 GB/s.
INTEL + NVIDIA APU (assuming LPDDR6' "between 10,667 and 14,400 MT/s"): 10667 MT/s * 384-bit / 1000 / 8 = 512 GB/s (the bandwidth of a Geforce RTX 4070) to 691 GB/s.

Not bad, especially the 700 GB/s. The up to 192 GB RAM is the more important value tho.
What for are 192 GB RAM needed? For big-ish (MoE) LLMs. Strix Halo's up to 128 GB RAM is just not cutting it. Starting from 192 GB RAM allows one to host the better/smarter LLMs.

192 GB with an Nvidia badge is going to cost you like $10k :X

If you've that kind of cash, wouldn't it be better just buy / rent a small nuclear reactor and data centre at that point?
