Definitely true that the FABs do deserve credit. But that alone wouldn't be enough to push monolithic designs for as long as Intel has, that's why I credited Intel's engineering team with 14nm + monolithic design. AMD's FAB partners weren't lacking prior to Ryzen. But AMD did give up monolithic designs, it wasn't an issue with their FAB partners. It was that their engineering team at the time had hit a limit or wall with AMD's monolithic design.

It's like Zen 2: +15% IPC and +10% clockspeed
Intel Ice Lake: +18 IPC and -10% clockspeed

Can a regular consumer afford it? Do they have the hardware to support something like that?

I mean, it's not like they needed a water chiller and INSANELY overbuilt server grade motherboard in order to demo it. And it's not like they attempted to hide the fact from the general public or anything.

It is what it is...

Haha I had a good laugh. In short Intel is still not much better than AMD thanks to their arrogance in their CPU dominance.


With 10% lesser clockspeed, the realistic IPC improvement is definitely <18% at best will give around 5% overall ST improvement. Yes Intel is still stuck at the 5% per gen slow pace, while charging 2x the price against their competitors.


I am 200% sure AMD is holding back the 16C as their trumph card for AM4+ socket.

4.1Ghz [email protected] part compared to 4.8Ghz on i7-8665U @25W part =17% lost of clock speed, so with 18% IPC uplift they are in the same place in TDP and performance, in theory it only helps Intel to make more CPU's per Wafer.

what about the integrated GPU? Is it the same on both parts?

Could be that the power savings from the clock speed drop was reallocated to the GPU effectively giving them the same TDP and CPU performance and improved GPU performance vs the previous mobile chip.

You said Intel hasn't done anything architecturally but they created a mesh architecture and were able to create a 28 core monolithic chip. Of course it's expensive since it's a monolithic chip. If they wanted to they could also just glue together their quad cores with a UPI link.

For sure. Gluing chips together is such a stupid idea. It would never work...

Is this before or after all of the performance that Skylake has lost after patching out numerous security flaws? If it's after, then we're not really looking at any gains at all.
