The latest Linux 6.1.9 kernel has delivered a massive performance boost — not for the best graphics cards, but for AMD’s long-forgotten Southern Islands and Sea Islands GPUs, launched over 13 years ago. According to Phoronix, these vintage cards powered by AMD’s GCN (Graphics Core Next) 1.0 and GCN 1.1 architectures now enjoy up to 30% higher performance.
It’s easy to forget about GCN 1.0 and 1.1—while not ancient, they feel like relics from another era of PC gaming. GCN 1.0 powered the Radeon HD 7000 series, while GCN 1.1 appeared in the mostly OEM Radeon HD 8000 series, save for a handful of exceptions. For many, these cards defined a generation of unforgettable gaming moments.
