節(jié)選兩段透露關(guān)鍵信息的段落：

Zen 4 is what a lot of people are waiting for, and, if the info I have is accurate, that wait will prove to be even more worth it. It is important to note that the one common thread in all Zen 4 chatter I have heard is resounding positivity. From IPC gains over 25%, a total performance gain of 40%, and even possibly (finally) 5GHz all-core thanks to the new (full node) N5 fabrication at TSMC! Now, I can’t say what is true and what is an over-exaggeration, however I was told from a trusted source that a Genoa engineering sample (Zen 4 server chip) was 29% faster than a Milan (Zen 3) chip with the same core config at the same clocks. Factor this in with what I have heard about the possible clock gains that N5 will enable over N7 and Zen 4 sounds like it is going to be a monster of a CPU.

Now I said I had Zen 5 info, unfortunately this comes from a different, less-proven source than my Zen 4 info, however they have said that the jump [to Zen 5 from 4] from will be about as much as Piledriver to Zen 1 design goal, which if you recall to earlier in this article was 40%. I was told from a 3rd source that Zen 5’s original design goal was 2.5 to 3 times the IPC of Zen 1 which roughly lines up with the perspective of a “Piledriver to Zen 1”-like jump.

PS：我發(fā)這些倒不是說這則消息是假新聞，也許是因?yàn)閯偝闪?，所以這個blog需要一些好料來提升下人氣，但是在查看了數(shù)家IT網(wǎng)站的相關(guān)文章后，消息源都是這個blog，所以是不是真的暫且不說，先觀察下沒壞處。。。
