NVIDIA will be launching its GeForce RTX 4090 in October, followed by the RTX 4080 in November, and the RTX 4060 in January 2023 at CES 2023. The Ada Lovelace flagship with 2x RTX 3090 levels of performance will launch in the final month of the third quarter (end of fall) while the RTX 4080 and 4070 will be released in the holiday season. The budget 40 series SKU will be announced in January during NVIDIA’s CES 2023 keynote.

The RTX 4090 is going to leverage a partially disabled AD102 die, the RTX 4080 with the AD103, and the RTX 4070 with the AD104. The core counts will vary from 18,432 to 10,752, and 7,680, respectively. The VRAM will also differ similarly, from 24GB GDDR6X on the RTX 4090 to just 12GB GDDR6/GDDR6X on the RTX 4070.
The AD102 and AD103 will be very similar in terms of layout with the only difference being in terms of a few GPCs. They’ll also leverage the same PG139 board. The RTX 4090 is known as the 330 SKU while the 4080 is the SKU 460. NVIDIA is set to announce the Lovelace parts in four consecutive months, with the RTX 4060 being the only GPU to be announced during a major event. (thenewspocket)
The AD102 and the AD103 GPUs are expected to utilize the same PCB, PG139, but the SKU will vary slightly with the RTX 4090 using the PG139-330 SKU and the RTX 4080 using a PG139-360 SKU. The RTX 4070 on the other hand will be based on a completely different board. The NVIDIA GeForce RTX 4060 will be the first Ada Lovelace card for 2023, being unveiled at CES 2023 and launching a few weeks later. The mainstream card is also expected to utilize the AD106.
