No new architecture this year
First up, NVIDIA said a successor to Ampere shouldn't be expected until 2022. Basically, it looks like we can expect a full new architecture every two years and perhaps some sort of refresh in the in-between years. NVIDIA will offer solutions both for the Arm and x86 markets. One year the company will focus on x86 and the other year Arm will be the focus point.The codename of the Ampere successor wasn't revealed, NVIDIA merely refers to it as "Ampere Next". The successor to the latter is expected in 2024 and was called "Ampere Next Next". Similarly, the first NVIDIA CPU will launch in 2023 and will get a "Grace Next" successor. The roadmap also lists the update cycle of the Bluefield lineup, NVIDIA's DPUs for the datacenter market.
Nothing about gaming was mentioned so there's no explicit confirmation that the GeForce series will get a fully new architecture in 2022. According to the rumor mill, the successor to Ampere is codenamed Lovelace.
