AMD CTO表示K8L的架构优于C2D，每瓦IPC比现有K8提升50%
When talking to both Phil and Pat, we got some interesting answers about advancements in Instructions Per Clock with the K8L Pat Conway said that we will see a “performance improvement of 150% over the next two years that will be within the same power envelope.” If you take into account that you can back off frequency and add more cores, some of this can be achieved now if you are counting IPC across all cores. (See below how simply pulling back on frequency by as little as 16% can have a huge impact on power draw.) Intel is bound by the same principles as well.

On IPC and AMD’s K8L Phil Hester had this to say: “We want to stay focused on upgrade compatibility. We must realize more IPC per watt, and our next-generation architecture will show a 50% improvement of IPC per watt.” So I came away with a somewhat clouded view on IPC, but I did get the distinct impression that AMD’s next-generation architecture would be on par or better than what we have seen with Intel’s Core 2 Duo, which is the low benchmark AMD must shoot for.

真这历害

如果论每瓦IPC，K8翻一番也比不上Merom，谈何架构优势。

K8跟Conroe比就行了，不用非跟Merom死磕吧

你在用90nm的K8和65nm的Merom来比和人家用65nm的K8L和Conroe比是一回事情吗？

我的意思是AMD回避绝对性能而大谈每瓦性能，很有可能是和K8相同规格的K8L仅仅是功耗降低了，实际性能提升不大。而Conroe想降低功耗比提升性能容易的多。

一切要出来才知道,现在大家都是猜测..

估计4-Core以上，K8L才能占到优势。

请注意，这里说的是每瓦IPC。

如果是每Hz IPC还值得期待，但是每瓦IPC……90nm的CD TDP 95w，65nm新步进的CD TDP 65w，每瓦IPC也差不多提升了50%。
