AMD Ryzen 3 5425C
AMD Ryzen 3 5425C 是基于塞尚一代的 Chromebook 处理器。它是 2022 年 "Barcelo "更新的一部分，与旧版相比，CPU 内核时钟频率高出 100 MHz。Ryzen 3 5400U.R3 5425C 集成了基于 Zen 3 微架构的八个内核中的四个。这些内核的主频为 2.7（保证基本时钟）至 4.1 GHz（Turbo），支持 SMT/超线程（8 线程）。芯片采用台积电 7 纳米工艺制造。5425C 是消费级 Ryzen 3 5425U 的Chromebook 版本。 Ryzen 3 5425U规格完全相同。
CPU 部分的性能应略高于旧版的 Ryzen 3 5400U在入门级产品中略胜一筹。
除了四个 CPU 内核，该 APU 还集成了 Radeon RX Vega 6 集成显卡，拥有 6 个 CU，频率高达 1600 MHz。双通道内存控制器支持 DDR4-3200 和节能 LPDDR4-4266 内存。此外，8 MB 三级缓存（与旧版的 4800U芯片相同）。
APU 的 TDP 规定为 15 瓦（默认值），笔记本电脑供应商可在 10 至 25 瓦之间进行配置（大多数芯片的配置高于 15 瓦）。这意味着该芯片适用于轻薄型笔记本电脑（但有风扇）。
