HP Envy x360 is great. It has a 6 (real) core AMD Ryzen 5 4500U, nice screen and absurd battery life (12 hours or something ridiculously long like that). https://rwmj.wordpress.com/2020/07/18/amd-zen-2-laptop/ The single thing I don't like about it is they've overloaded the backslash/pipe key on to another key.
I don't want to buy an expensive laptop with only 16G RAM.
I'll buy one of these. Not because of the CPU -- despite of that. Ryzen would be great but there's no thin&light Ryzen laptop with great screen and great build. Not sure why. However, apart from the performance disadvantage (that's not extremely serious), the 9310 is a great package overall (or at least I can't find anything more compelling on the market with good battery life, good screen, good docking story (TB), g…

This leads to random black external screens and network/usb disconnects. It is so unreliable that I stopped using it for real time communication. (Note: I have the xps 13 2-in1 2019 laptop, i7-1065G7)
These laptops are gorgeous new, but they are SO fragile. One of the screen hinges is broken, I've replaced numerous keys, the keyboard is now developing some debounce/key registration issue all over the right-hand side, the speakers are both blown (left first then the right), the trackpad sits 0.5cm above the case (needs replaced), the glue holding the rubber to the bottom of the case expanded with heat and leaked out everywhere. Probably more I've forgotten
I'd still consider buying another, but I'd also strongly consider changing vendors once this machine finally dies

Is the Huawei Matebook AMD edition available in your country? They are available with Ryzen processors and even better screens with a 3:2 display ratio.

memory tagging is like a hardware based ASAN that eliminates many memory bugs and improves memory debugging. So its potential is well beyond mitigating ROP (though all these benchmarks will change with memory tagging enabled :-))).
Intel patent document "US2020/0125502 Low memory overhead heap management for memory tagging", has more info on how this might work: https://www.freepatentsonline.com/20200125502.pdf
For a great background primer on why to use this see the brilliant work of Konstantin Serebryany https://arxiv.org/ftp/arxiv/papers/1802/1802.09517.pdf
IMO this is long overdue on Intel architecture and the main reason why one might want to be excited about Tiger Lake
I can imagine it will lead to a lot of effort for Linux: malloc implementation, glibc, compilers, toolchains and debugging tools ... and lots of discussions about why and when it should be enabled. (IMO you want this in production always)
I moved to XPS 15 as my first non-Mac machine in over 10 years, and I must say I'm far from impressed by the build quality. These laptops are gorgeous new, but they are SO fragile. One of the screen hinges is broken, I've replaced numerous keys, the keyboard is now developing some debounce/key registration issue all over the right-hand side, the speakers are both blown (left first then the right), the trackpad sits 0…
