Sony PlayStation 5 receives new 6 nm AMD Oberon Plus with a few quality of life improvements
Last month, we reported that Sony had released a third PlayStation 5 revision since the console's introduction two years ago. As we discussed, Sony is shipping the PS5 in most regions with model numbers CFI-1202A or CFI-1202B for the disc version and digital edition, respectively. In summary, the latest PS5 revision is up to 300 g lighter than the older CFI-1100 revision. Additionally, Sony has shaved 600 g from the PS5's launch weight thanks to a smaller mainboard and a revised cooling system.
Subsequently, Angstronomics has discovered that the latest PS5 revision also contains a new AMD APU. Codenamed Oberon Plus, the APU replaces Oberon APUs that Sony has used until now in all PlayStation 5 SKUs. According to the website, AMD has built Oberon Plus around TSMC's N6 process, which provides 18.8% greater transistor density than the 7 nm node on which Oberon is based. In practical terms, Oberon Plus has a 15% smaller die than Oberon, measuring in at 260 mm² while maintaining its 10,600 million transistor count.
A byproduct of a more efficient die is reduced power consumption, which YouTubers like Austin Evans have already observed. Purportedly, the latest PS5 revision consumes 20 W to 30 W less than its predecessors, equating to just over 11% less than first and second revision consoles. Moreover, reduced power consumption corresponds with lower temperatures and quieter fans. You can find more differences between the three PS5 revisions, such as temperature measurements, in Evans' corresponding video on the subject.
