The funniest thing is, which actually tells the most about his character: tuned at gaming 🤣🤣🤣
NOBODY EVER tuned ANYTHING for gaming at Intel when designing an uarch.
He didn't said that.
He said that skylake was "tuned", but without specifying for what, and one of the results is the performance in gaming.

You either speak even worse English than him, or you just follow him for so long that you can read his mind. What he wrote does not mean what you state now, at least not in English.

Yes, my english is bad, but still.
He was bragging that he was part of what made Skylake good, that he helped tweak that thing to extract the maximum performance the arch could deliver. The performance "at" gaming is a consequence of this, not that Skylake was made thinking about how to have the best performance "in" gaming.

You take David Kanter seriously?

Well , IPC is application depended. ZEN 2 may have higher IPC in Floating Point in Cinebench but that doesnt actually mean it has the higher IPC in general.
I dont know it may have the higher IPC but taking only Cinebench to showcase this is not the complete picture.
I would like to see a review with 10-15 applications having both Integer and Float benchmarks and then we can come to a conclusion who has the higher IPC.

Remember we're talking Renoir vs. Intel mobile chips specifically. You can't just compare Zen2 to Coffeelake on desktop and come to a conclusion. In mobile, you've got to normalize for power (I guess?) for things to be meaningful. Unless it's okay for Intel to win benchmarks by burning up 2x more package power.

I have a ton of respect for David Kanter and his knowledge of digital IP design far outweighs mine. With that said, appeal to authority doesn't go very far with me so without an argument with data to back it up, a simple no response is meaningless to me.

Now, from what I've seen, he is correct in terms of Icelake, but Icelake also doesn't have any skus with more than 4 cores, doesn't scale well in frequency compared to AMD or intel's own 14 nm, and doesn't seem to offer any significant power savings to speak of compared to intel 14 nm, so it's hard to mark that one in the win column.

The question was about IPC though, so he's right. Ice Lake is ahead in IPC.

It may be littered with other problems, but if you're gonna talk about IPC, then currently in x86 Intel is still technically in the lead.

We'll see if that holds up later this year though.

IPC will be almost the same in desktop vs mobile.

perf/watt is a different measurement, it doesnt have an impact in IPC performance.

At what applications ??

On average of a multiple applications. I dunno, if you want an industry standard or something use Spec results, they'll tell you the same thing. Sunny Cove is ahead of Zen 2 and Skylake.

My point is that when your perf/clock lead is with a chip that is mobile only with a limited number of SKUs, it's not exactly a win. AMD has the perf/clock lead in desktop, server, and mobile above 4 cores. Intel has a lead in mobile 4 cores and below where it still loses in overall performance and efficiency. So who has the "IPC lead"? It's not a straight forward decision at this particular point in time.

Comparing Icelake with Intel's 14nm CPUs or Zen 2 in desktop performance right now is like comparing Apple's A13 with Intel's 14nm CPUs or Zen 2 in desktop performance! lol

Yes ok, what are those applications ?? do you have a link with results from those applications ??

We have links of Spec int and Spec float in a single thread at a given clock speed for ZEN 2 vs Ice Lake ??
Not single thread and not at fixed clock speeds as Andrei has repeatedly said that its not relevant, but here you go:
As you can see from the final graph in that page Ice Lake is ~10% ahead in PPC vs Zen 2 in int and ~13% ahead in fp.
