I've got a 4800hs 8-core laptop that should be showing up on my doorstep later today. My kid is doing some heavy video/graphics work in Adobe in her undergraduate program, and going to try this as a potential desktop/workstation replacement since she is still a bit of a nomad as a student. Her current laptop just can't handle the work without trying to cook itself - but will have some apples to apples rendering compa…

Mind sharing the brand/model?

Nice - assuming it has USB-C? The external USB-C SSDs are great for source media.

I believe so.

Is what we have on route. No SD slot... but most of the other ports one might need.

One of the key reasons we might not see this yet is Thunderbolt 3 support. Thunderbolt is noticeably missing from the new AMD laptops on the market - e.g. the Asus ROG Zephyrus G14 (2020). Thunderbolt itself is an Intel technology. The emergence of USB 4 (effectively TB3) as a standard will change that. Perhaps we'll see that become available in AMD's next generation of CPUs.

Is thunderbolt support tied to the CPU?? I thought it was just a slot that can be added in the mother board for any powerful CPU

Thunderbolt can be added to anything. There are Thunderbolt 3 AMD motherboards currently even, just only on desktop where it's borderline pointless.

The main thing is Intel's CPUs integrate a chunk of the thunderbolt 3 responsibility (which Ice Lake takes even further: https://www.anandtech.com/show/14514/examining-intels-ice-la... ). So it's an easy add-on for OEMs, which makes it more common & widespread as a result.

Also relevant being this is AMD's first time being in a premium laptop position in a long, long time. Just having AMD in a premium offering is itself a new scenario for OEMs.

Yeah it does. 1TB will last a while but depending on what she’s working on she could easily have 100GB of source material per project.

Despite the protestations of l33t Cyberhaxxing Z3r0 Cools everywhere, you only have to turn off hyper-threading if you are sharing a machine with someone you don't trust. If someone is on your machine and you don't know it, they don't have to use side-channel attacks. They'll can just use any of the thousands of other ways of privilege escalation to read the super-secret information you have stored in RAM, or find it…

Are you aware of any spectre POC that in JavaScript you can break out of that sandbox and do anything worth while?

Is what we picked up. First time I've ordered a laptop without actually messing with it first. This likely will be used as more of a workstation/desktop replacement. Looking forward.

Package just showed up! Unboxing now.

Btw, does anyone know how to buy boxed (PIB/WOF) AMD Rome EPYCs at reasonable (not full MSRP) market prices rather than OEM/tray (non-WOF) ones?

I recently ordered WOF EPYCs from a small business that fronts one of the largest distributors of PC components, and they/distributor sent the no-warranty OEM/tray ones instead. (30 day warranty + 15% restocking fee is no deal at all.)

Slightly off topic, but with the G14, it was made clear that the RTX 2060 is the 60W max-Q version. Do you know if this Asus TUF RTX 2060 is the full 90W version? (Well, it sounds like you're getting the 1660 Ti, but the same question applies, since they also sell that in both 60W Max-Q and full 80W versions.)

ETA: This seems to hint it is the 90W version https://www.ultrabookreview.com/36108-asus-tuf-gaming-fa506i...

Yeah, my understanding is that browsers added mitigations for this sort of stuff - so I'm curious about it too.

Does this new intel CPU have 'fixes' for all issues like spectre and meltdown, where you were supposed to turn off hyperthreading for better security? I'm just curious if the fixes for those (and other similar vulnerabilities) are starting to make their way into silicon, but also that the fixes recommended usually slow cpu's down quite a bit too.

Or.. if you run untrusted code, such as a web browser with Javascript enabled.
