AMD Business Mini PC Review Snippet Zen 4

搭载 Ryzen 7 H 255CPU 的系统，如 GMK NucBox K12，现在正变得越来越普及。不过，在使用过其中几款系统一段时间后，买家可能会考虑较旧且往往更便宜的 Ryzen 7 7840HS, Ryzen 9 7940HS或 Ryzen 9 7940HS选项。性能也与 Ryzen 9 8845HS性能之前的报道可以说，处理器 SKU 太多，而它们之间的差异化因素却很少。

下面的基准测试表明，Ryzen 7 H 255 的性能与上述替代产品几乎完全相同。这四款处理器的内核数、线程数、缓存大小、集成的 Radeon 780M图形处理器，甚至没有 NPU。事实上，Ryzen 7 H 255 实际上只是上一代 Zen 4 处理器的翻版，尽管它是在速度更快、效率更高的 Zen 5 处理器中推出的。

对于大多数 HTPC 或 4K 流媒体来说，整体性能仍然非常出色，尤其是与过时的 Iris Xe 或 Radeon RX Vega 迷你 PC 相比。不过，希望省点钱的用户会发现，近 3 年前的 Ryzen 7 7840HS 可以提供更好的性价比。自 Ryzen 7 7840HS 推出以来，AMD CPU 的命名规则已经发生了变化，因此 Ryzen 7 H 255 并没有为那些可能不了解最近变化的买家带来任何便利。
