7nm beats 14nm or 10nm by definition.

The definition cannot translate between different fabs, in fact TSMC's 7nm is generally equivalent to Intel's 10nm on many metrics, or were you expecting Samsung's 7nm to be equal to TSMC's 7nm too?
As for the rest, we'll see with a shipping model.

Astar is spot on, this is game changing (no pun intended :). At the end of the day there are no fancy tricks here. 7nm beats 14nm or 10nm by definition. Any small differences between designs by intel and AMD are absolutely eclipsed by the reduced chip size benefits; lower power consumption, improved performance and less resistance creating less heat. AMD is in a unique position here thanks to TSMC and will be the leader for performance for the next 12-24 months. Benchmarks will reflect the physics.

As for Thunderbolt, yes I want it, but mostly I wanted it for eGPU as the flagship laptops with high end intel CPU's were throttling so much I wanted to go external GPU. Now I don't have to with the AMD Ryzen 4000 series 7nm chips. So I no longer care about Thunderbolt 3 or 4, sorry Intel. 


Furthermore, AMD's presentation chart about the mobile Ryzen 7 4800H at 45W beating the Intel i7-9750H 6C/12T at 45W and even the Intel i7-9700K 8C/8T desktop at 95W by 39% and 13% respectively, says it all.

在PPT的尾注很明显的提到了对比的i7-1065G7是在XPS 13 7390 2-in-1中的，在这款笔记本中i7-1065G7的PL1和PL2都是46W。我不是说Ryzen 7 4800U就是跑在15W，但至少AMD并没有在PPT中用标准15W的i7-1065G7去贬低intel的性能

NBC's load average for this model is 43.1W, so what you say is either impossible or NBC's power gauge is malfunctioning.

Definitely, and 1065G7 is 25W max anyway.

What's your point? You don't even realise that the Ryzen 7 4800U is ONLY 15W?

If so this article's point about performance delta between laptop chasis, while valid, is moot! If the Ryzen 7 4800U at 15W can beat an Intel at 25W, Intel is so screwed.

I don't know if this article's writer is an Intel sympathizer, but the point about differences in cooling is not as relevant. At least I wouldn't insinuate that AMD has been trying to be disingenous, the way Intel is well known to be when it comes to benchmarking. Choice of benchmarking software is one thing, at least AMD isn't known for crippling Intel CPU performance the way Intel has been known to do when AMD hardware is detected!

Furthermore, AMD's presentation chart about the mobile Ryzen 7 4800H at 45W beating the Intel i7-9750H 6C/12T at 45W and even the Intel i7-9700K 8C/8T desktop at 95W by 39% and 13% respectively, says it all.

I agree that the tests of actual units in hand will be key. Please test the Dell G5 gaming laptop in both AMD & Intel variants! Can't wait.

But in this instance, if AMD can deign to compare a laptop Ryzen to an Intel desktop, surely the cooling capacity differences have already been taken into account! The Intel desktop surely has far superior cooling capacity than any engineering-prototype sample laptop chasis for the mobile Ryzen 7 4800H! I doubt AMD put the comparison Intel desktop motherboards in a sealed shoebox!

Mostly likely, Intel is farked!

Having read more on this I suspect they're playing with binning. They pitted a random 7390 against their best bin, they could shave 10W off 4800H just by binning, no underclocking after all.
Regardless, they'll be competing with Tiger Lake, not Ice Lake anyway.

AMD did specify which laptops were used for reference on the endnotes of the slide deck (see Anandtech's piece on the release).

Dell XPS 7390 with Core i7-1065G7 vs 4800U.
Asus Zephyrus M GU502GV with Core i7-9750H vs 4800H.

Thanks for pointing that out! Still, a larger sample size is preferred instead of just two. The XPS 13 and Zephyrus M GU502 don't represent the average Core i7 or Ryzen 7 laptop. That is what i wanted to get across the most.

AMD needs to support USB 4.0/Thunderbolt 3 quickly. And if Comet Lake-H turns out to be faster than 4000 Series APUs, NVIDIA's Ampere is coming soon too, AMD may fall behind again in mobile chips.
