Lenovo may have confirmed that a 12GB RTX 5070 Laptop GPU is coming

The rumor surrounding an RTX 5070 Laptop GPU with 12GB of VRAM isn't new, but after the latest findings, it's almost certainly in development. Evidence has shifted from vague speculation to appearing in official, public-facing documentation from Lenovo. As of today, Nvidia still hasn't officially confirmed this SKU, but the breadcrumbs left behind by the laptop manufacturer suggest a launch is imminent.

The most compelling evidence comes from Lenovo's Product Specifications Reference (PSREF) spotted by Huang514613 and VideoCardz, which was recently updated with several 2026 laptop entries. These entries include the new Legion Pro 5, with multiple configurations explicitly listing the “Nvidia GeForce RTX 5070 12GB GDDR7”. Interestingly, some listings show a 115W TGP with a 2347MHz boost clock (matching the 8GB version), while others list a lower 1425MHz clock, which could indicate a “Max-Q”-style efficiency variant. Moreover, it also shows some Yoga Pro and LOQ lineup models featuring the 12GB 5070 with a 115W TGP. Because Lenovo still has active listings for the 8GB model, it appears they plan to offer two distinct memory tiers for the RTX 5070.

Before this, the same leaker had shared an entry of an Asus ROG Strix Scar with an RTX 5070 Laptop GPU. However, a single entry mentioning the 12GB variant of the RTX 5070 still left many sceptical, as it could be just a typo. However, given the sheer amount of entries spotted at Lenovo's PSREF, it looks like a 12GB variant is indeed coming.

The standard RTX 5070 Mobile (GB206) uses a 128-bit bus. Normally, this limits you to 8GB (4x 2 GB modules), which is used by the current RTX 5070 Laptop GPU. However, using 3GB modules on the existing 128-bit bus would allow Nvidia to reach 12GB without moving to a larger, more expensive 192-bit chip (GB205).

The individual who spotted these entries has also claimed that the official embargo for this 12GB SKU lifts in late April 2026. This aligns with the “spring refresh” cycle typically seen for gaming laptops ahead of the summer graduation and back-to-school season.

KitGuru says: A 12GB variant of the RTX 5070 would certainly make it more compelling. However, due to current industry conditions, pricing might ruin what could possibly be a sweet spot for laptop GPUs.
