CPU-Z測試Win7安全性更新"KB4056897"對Intel處理器效能影響

Q8400+2gram已更新懶得測因為電腦只有拿來上網跟看新聞而已

這應該是Acer bios的bug 網路上也有人有相同的問題

為了偷懶的朋友,節錄了結論
Conclusion, so far
Well, there you have it. Desktop users have little to worry about in terms of performance loss, particularly gamers. We've yet to test older CPUs, but given the type of workloads we’re seeing impacted by the patch, I don’t think there’s going to be an issue with any desktop hardware, but we’ll certainly report back if there is.

The reduction in 4K read performance for high speed NVMe drives is a concern and while this shouldn’t impact any games, any application that is sensitive to this might show a reduction in performance. Of course the brief list of applications I tested showed no real reduction in performance period.

The issue nonetheless remains and is one that has a far bigger potential in affecting servers. It's a serious concern for data centers both on the side of performance and more importantly, security. That's not our area of expertise or interest, so we'll leave that testing to those better equipped to tackle it.




只更新windows 是無法完全修復這個硬件級設計缺陷
還需要更新bios uefi

以下是更新後影響

因為是硬體架構層級的缺陷,所以配合CPU的主機板也要同步修補才有用的觀念嘛?
這樣下來真的很可怕。要是不會更新BIOS,豈不是只能拔intel CPU下來當鑰匙圈?

只更新Patch就好了
我這台多年前的文書上網機E5300 也沒BIOS可更新了

喔,有些項目要10%了我決定等到出第九代cpu再買intel,簡直詐欺啊
可測試 CrystalDiskMark(尤其是ssd) 3dmark免費版
看看是否有降效能
之前英特爾是靠作弊得到效能.現在不能作弊的話9代應該也不會快多少.不如一樣買8代更新就好
看樓上的反應...

intel CPU出大包,怎麼感覺AMD沒撿到甚麼便宜...
