AMD發布銳龍7000三款新U 開啟PBO 2自動超頻技術能效暴漲47%
首批四款X系列之後,AMD今天為Zen4銳龍7000系列家族帶來了三名新成員,都是型號末尾不帶X的標準版,頻率、功耗有所降低。

銳龍9 7900:
12核心24線程、二級緩存12MB、三級緩存64MB、主頻3.8-5.4GHz,自帶幽靈PRISM散熱器。
相比於銳龍9 7900X,基準和加速頻率分別降低了900MHz、200MHz,競爭對手i9-13900、i9-12900。
銳龍7 7700:
8核心16線程、二級緩存8MB、三級緩存32MB、主頻3.8-5.3GHz,自帶幽靈PRISM散熱器
相比於銳龍7 7700X,基準和加速頻率分別降低了700MHz、100MHz,競爭對手i7-13700、i7-12700。
銳龍5 7600:
6核心12線程、二級緩存6MB、三級緩存32MB、主頻3.8-5.1GHz,自帶幽靈STEALTH散熱器。
相比於銳龍5 7600X,基準和加速頻率分別降低了900MHz、200MHz,競爭對手i5-13600、i5-12600。
它們的熱設計功耗都是65W,同樣集成2個計算單元的RDNA2架構GPU,支持DDR5-5200、PCIe 5.0,封裝接口AM5,可搭配B650系列主板。
國行價格稍後公佈。

性能方面,稍後我們會同步放出首發評測,先來看看兩個有意思的官方數據:
銳龍9 7900打開增強型PBO 2自動超頻技術後,多線程性能可提升多達34%,而如果搭配水冷(估計沒人這麼幹),就能將這一幅度提高到39%。

銳龍9 7900測試CineBench R23多線程的時候,系統功耗只需177W,相比於銳龍9 7900X 285W,能效高出多達47%。
