Released yesterday, the Steam Deck portable console, which combines a PC with SteamOS (Linux) and a design that resembles a Nintendo Switch, runs on hardware that is architecturally very similar to the PlayStation 5 and Xbox Series S | X. Inside, we find APUs that connect Zen 2 processor cores and RDNA 2 generation graphics. However, unlike them, it has slower LPDDR5 memory.
In leaked AMD roadmaps, said chip appeared under the codename Van Gogh. It was supposed to be released this year, but due to the semiconductor crisis, it already seemed like we wouldn’t see it and AMD would skip it in favor of others. If the above information is still valid, the APU is manufactured using a 7nm process like other current AMD processors and graphics and has a TPU set at 9 W. (Valve on Steam Deck indicates it will be 4 to 15 W.)

AMD currently offers two main series of APUs. The Renoir chips combine Zen 2 processor cores and Vega architecture graphics. This year Cezanne it was later upgraded to Zen 3, but the GPU stayed with the old architecture. RDNA 2 ICs were to appear in computers only with Van Gogh, who was targeting special “premium devices” this year, and is expected to do so next year at APU Rembrandt (Zen 3+ and RDNA 2), which it should show up in normal notebooks and low-power computers.
AMD itself is still silent on the Van Gogh family, but it does not seem likely that this APU will be widely available in other products. On a similar basis, a relatively powerful computer the size of a cigarette pack could hold up.
