AMD 在 2022 年年末带来了 RDNA 3 架构的 RX 7900 系列显卡，两年之后它的接班人 RDNA 4 来了，说真的如果纯看传统光栅性能的话基于 RDNA 3 的 Radeon RX 7900 XTX 是完全可以与对手旗舰扳手腕的，但 AI 与光追性能确实存在短板。今年年初的 CES 2025 上 AMD 就公布了基于新一代 RDNA 4 架构的 RX 9070 系列显卡的存在，新的 RNDA 4 架构 AMD 明显是想强化此前在 AI 与光追性能上的短板，新的 FSR 4 就是基于机器学习所提供的超分技术，游戏画质会比 FSR 3.1 好得多，而且光追与传统光栅性能也会给大家带来惊喜。

而今天是 Radeon RX 9070 XT 和 RX 9070 这两款显卡正式解禁的时间，我们就一起来亲自感受一下，RDNA 4 架构下的新品究竟会带来什么样的游戏体验。
