Blackwell reached a Steam share of 1.04% within 4 months and 1.78% within 5 months.
So I checked how long it took other Nvidia generations to reach 1% and 2% Steam share.
Pascal launch 05/2016 (let's ignore the Titan X), Steam share >1% for the first time 08/2016 -> 3 months
Turing launch 09/2018, Steam share >1% for the first time 02/2019 -> 5 months
Ampere launch 09/2020, Steam share >1% for the first time 01/2021 -> 4 months
Ada-Lovelace launch 09/2022, Steam share >1% for the first time 03/2023 -> 6 months
Blackwell launch 01/2025, Steam share >1% for the first time 04/2025 -> 3 months
Pascal launch 05/2016 (let's ignore the Titan X), Steam share >2% for the first time 09/2016 -> 4 months
Turing launch 09/2018, Steam share >2% for the first time 04/2019 -> 7 months
Ampere launch 09/2020, Steam share >2% for the first time 02/2021 -> 5 months
Ada-Lovelace launch 09/2022, Steam share >2% for the first time 06/2023 -> 9 months
Blackwell launch 01/2025, Steam share >2% for the first time (probably) 06/2025 -> 5 months
