We have been covering leaks and rumors about Ampere GPUs pretty much non-stop for the past few weeks so it's only fair we cover a dissenting voice as well. The venerable Igor of Igor's Lab (a very reliable source I might add) has stated that he does not expect NVIDIA to launch/announce Ampere GPUs in March at GTC 2020 and instead expects the standard August/September launch window.
