AMD reheats last year’s Ryzen AI and X3D CPUs for 2026’s laptops and desktops
摘要
AMD在CES上发布了Ryzen AI 400系列处理器，作为2024年Ryzen AI 300系列的后续产品。新款芯片主要进行了小幅升级，包括略微提升的CPU与NPU时钟速度，以及更高的内存支持速度。例如，Ryzen AI 9 HX 470的最高加速频率为5.2 GHz，并支持LPDDR5x-8533内存，其NPU算力提升至60 TOPS。文章指出，这些更
Intel, AMD, Nvidia, and other chip companies usually have some kind of news to announce at CES to kick off the year, but some of those announcements are more interesting than others. Sometimes you see new chips with significant speed boosts and other new technologies, and sometimes you get rebranded versions of old silicon meant to fill out a lineup or make an existing architecture seem newer and more exciting than it is.
AMD's Ryzen CPU announcements this year fall firmly into the latter camp—these are all gently tweaked variants of chips that launched in 2024 and 2025.
"New," for certain values of "new"

Officially the follow-up to the Ryzen AI 300 chips announced in June 2024, these processors offer some modest clock speed improvements and faster memory support. The new Ryzen AI 9 HX 470 has a peak boost clock speed of 5.2 GHz and support for LPDDR5x-8533, for example, up from 5.1 GHz and LPDDR5x-8000 for the Ryzen AI 9 HX 370, and its built-in neural processing unit (NPU) is capable of 60 trillion operations per second (TOPS) rather than 50 TOPS.
