They're coming alright. The ID is unique to each SKU and aids in device tracking. A list leaked. Not all of those IDs will be used for final SKUs; this is more of a test plan.

The GeForce RTX 4090 GPU would have ID of 2684, according to this leak. This GPU would be based on a scaled-down AD102 GPU with 16384 CUDA Cores and 24GB of GDDR6X memory. Also a listing of mobile devices is in there:

; AD102
NVIDIA_DEV.2684 = “NVIDIA GeForce RTX 4090”
; AD103
NVIDIA_DEV.2717 = “NVIDIA GN21-X11”
NVIDIA_DEV.2757 = “NVIDIA GN21-X11”
; AD104
NVIDIA_DEV.2785 = “NVIDIA AD104”
NVIDIA_DEV.27A0 = “NVIDIA GN21-X9”
NVIDIA_DEV.27E0 = “NVIDIA GN21-X9”
; AD106
NVIDIA_DEV.2820 = “NVIDIA GN21-X6”
NVIDIA_DEV.2860 = “NVIDIA GN21-X6”
; AD107
NVIDIA_DEV.28A0 = “NVIDIA GN21-X4”
NVIDIA_DEV.28A1 = “NVIDIA GN21-X2”
NVIDIA_DEV.28E0 = “NVIDIA GN21-X4”
NVIDIA_DEV.28E1 = “NVIDIA GN21-X2”

However, the mobile series is not anticipated until Q4'22 or early Q1'23, three months after the debut of the NVIDIA GeForce RTX 40 desktop product announcements.
