Intel Core i7-12700H with RTX 3070 Ti

This configuration suits users who want a 14 core, 20 thread Alder Lake processor hitting 4.7 GHz max turbo paired with an RTX 3070 Ti graphics card carrying 8 GB GDDR6 video memory at 150W TGP and 1510 MHz boost clock. Buyers needing a smaller screen, lower weight or a different GPU tier should evaluate other models.

64 GB DDR5 4800MHz and 8 TB PCIe 3.0 NVMe

The system includes 64 GB of DDR5 4800MHz memory in dual channel (2 x 32 GB) and 8 TB of PCIe 3.0 x4 NVMe storage (2 x 4 TB M.2).

Questions about this item

Does the 64 GB DDR5 4800 MHz memory need a matching SO-DIMM kit to reach dual-channel speed?

The 64 GB capacity is already populated as two 32 GB modules running in dual-channel mode at 4800 MHz.

Can the RTX 3070 Ti 8 GB GDDR6 drive an external 1440p 240 Hz display over HDMI?

The laptop's HDMI output supports the 2560 x 1440 panel at 240 Hz, so an external monitor with the same timing will work.

How do I confirm the 8 TB PCIe 3.0 x4 NVMe array is recognised after first boot?

Open Disk Management in Windows 11 Home and verify two 4 TB NVMe volumes totalling 8 TB appear with healthy partitions.
