If something is incomplete we say it's circumcized.E.g. same GPU chip but with more deactivated compute units (like 5070 vs 5070Ti), then we say the weaker version has a circumcized chip. Or a car variant with less PS has a circumcized engine. It's not slang, just a normal phrase, magazines etc will use it as well.
For example here:Radeon Pro W7700: The gap filler with a heavily circumcized chiphttps://www.computerbase.de/news/grafikkarten/radeon-pro-w7700-der-lueckenfueller-mit-stark-beschnittenem-chip.86126/
