长度增加14%，宽度不变，晶体管数量增加自行计算。请问IPC提高19%靠什么？真以为改改设计就行了？AMD CTO Mark接受anandtech[url=https://www.anandtech.com/show/16176/amd-zen-3-an-anandtech-interview-with-cto-mark-papermaster]采访原文[/url]如下。anandtech就是测spec06被泥潭鄙视的野鸡测试媒体，因为泥潭认为指令集不同，性能没可比性。
[quote]IC: While the x86 market for both client and enterprise is very competitive, there is increasing pressure from the Arm ecosystem in both markets, it’s hard to deny. At present, Arm’s own Neoverse V1 designs are promising a near-x86 level of IPC, and subsequent 30% year-on-year architectural uplift, at a fraction of the power that x86 runs at. While AMD’s goals so far have been achieving peak performance, like in Zen 3, but how does AMD intend to combat non x86 competition, especially as they are starting to promise in their roadmaps more and more performance?
MP: We won’t let our foot of the gas pedal in terms of performance.It’s not about ISA (instruction set architecture) - in any ISA once you set your sight on high performance you’re going to be adding transistors to be able to achieve that performance. There are some differences between one ISA and another, but that’s not fundamental - we chose x86 for our designs because of the vast software install base, the vast toolchain out there, and so it is x86 that we chose to optimize for performance. That gives us the fastest path to adoption in the industry. We have historically have lived in nothing but a competitive environment - we don’t expect that to change going forward. Our view is very simply that the best defense is in fact a strong offence - we’re not letting up![/quote]CTO说：指令集(x86 or arm)和性能没关系，任何构架的处理器，只要你追逐高性能，就需要增加晶体管数量。x86和arm构架，指令集是不同的，但那个不是作为基石的本质原因。我们选择x86作为设计是因为大量的软件支持，大量的工具存在，所以我们选择x86去优化它的性能。
泥潭觉得功耗，指令集是性能关键的去和Mark打一架吧。最后，台积电领先intel的完整2代差的工艺(5年差距)，相当于拿14nm终极产品RKL去打32nm初代i7 970(前后十年，intel自己停了5年)，泥潭可以用这两款cpu去跑下魔兽世界，看看fps差多少。了解下工艺水平和晶体管数量带来的性能差距。
