Zen2 將內建 Spectre mitigations 預防機制(看完原文可知)

如果你一直關注正在進行的 "Spectre" 和 "Meltdown" 事件，那麼你知道英特爾是這兩個芯片漏洞最受影響的廠商。 AMD公司 CEO Lisa Su 重申了AMD之前的立場，即公司的晶片不容易受到 Meltdown 的影響，也沒有涉及到一些潛在的Spectre漏洞。

Lisa Su 的解釋是：

Su 說：對於 Spectre 變種1，我們將繼續積極地與我們的生態系統合作夥伴合作進行緩解措施，包括已經開始推出的操作系統軟件包。 我們仍然認為 Spectre 變種2 在AMD處理器上很難被利用。但是，我們正在部署與操作系統補丁相結合的CPU微碼包，並提供其他緩解措施。

Su 補充說：“從更長遠的角度來看，我們已經在我們未來的處理器內核中包含了一些變化，從我們的 Zen 2設計開始，進一步解決潛在的類似 Spectre 的攻擊。我們將繼續就這些漏洞與業界密切合作，並致力於保護AMD用戶免受這些及其他安全威脅的侵害。“

換句話說，直到2019年AMD才解決了它的 Spectre 問題。基於AMD公司最近透露的廣泛的路線圖，下一代 Zen2 架構將在明年才會發布。

Spectre mitigations will be built into Zen 2
If you’ve been following the ongoing Spectre and Meltdown saga, you know that Intel has been the vendor most affected by the two chip vulnerabilities. Lisa Su, AMD’s chief executive, reiterated AMD’s prior position that the company’s chips aren’t vulnerable to Meltdown, nor to some of the iterations of potential Spectre exploits.

Here’s how Su explained it:

“For Spectre variant 1, we continue actively working with our ecosystem partners on mitigations, including operating system packages that have begun to roll out,” Su said. “We continue to believe that variant 2 of Spectre is difficult to exploit on AMD processors. However, we are deploying CPU microcode packages that in combination with operating system patches, provide additional mitigation steps.

“Longer term, we have included changes in our future processsor cores, starting with our Zen 2 design, to further address potential Spectre-like exploits,” Su added. “We continue to collaborate closely with the industry on these vulnerabilities, and are committed to protecting AMD users on these and other security threats, as they arise.”

Put another way, it won’t be until 2019 that AMD solves its Spectre problem. Based on AMD’s extensive roadmap that the company recently revealed, the next-gen Zen 2 architecture won’t be released until next year. <- 女支者自己的結論
