測了很多L3 latency跟bandwidth,不過重要的是Benchmark。
因為3d-cache的原因,Milan-X的頻率大約比平常Milan低5%

OpenSSL,Milan-X稍慢,不意外,ssl不需要cache。

Milan-X在編譯測試上取得7.6%的領先,如果同頻率的話約12.5%

轉碼測試上約 5% 領先,同頻率約10%

7-Zip 跟轉碼測試差不多5%,同頻率10%。

YCruncher幾乎沒差別,同頻率多約5%。
作者結論: "總而言之,V-Cache既是一項非常有趣的技術,也是一個不錯的性能增強器,這讓我對AMD下一步的技術發展非常期待。"
------------------------------------------------------------
測試Milan-X很困難也很花錢,你需要租下整個64核的cpu。

這位作者(群?)的文章都很好,可以考慮贊助他們。

-----------------------------------
V-Cache目前在Zen3上面無法完全發揮,期待Zen4版可以因為加大L2,ddr5與更好的設計能把效能發揮出來。
5800x3d能在遊戲上發揮嗎?我是抱著懷疑的態度,希望AMD能跌破大家的眼鏡。
