Well, the AYANEO 2021 line used Vega GPUs, so that might be the “gen before” at least as far as GPUs. You see, the Deck uses a Zen2 CPU (current gen is Zen4) while the GPU in the Deck is RDNA2 (current gen is RDNA3). So while the CPU is 2 generations back, the GPU is only one generation back from bleeding edge. And frankly GPUs last quite a while, and CPUs aren’t the bottleneck for games, so either one not being bleeding edge isn’t even an issue.
