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 resul…

Oh I never knew this. Thanks for the link. I think AMD is catching up in every possible way and thats a good thing. I hope we get more cool stuff sooner from them!

I'm really hoping apple puts these AMD mobile chips in their next MacBook Pro. At the moment I'm not seeing much reason to upgrade from my 2015 model, but if I could have 8 cores, that would a different matter...

I think Apple is already in the process of making their own chips. I'm thinking that they'll release an ARM chip for laptops. They are already blazing out on the mobile side.

The 65W is a bit misleading, according to https://www.techpowerup.com/265695/intel-core-i9-10900f-can-... and https://wccftech.com/intel-core-i9-10900f-10-core-desktop-cp... it is allowed to draw 170W in PL1 mode and up to 224W(!) in PL2 mode. Those numbers should feature prominently alongside the 65W figure. It does not look good for Intel at the moment.

Yeah TDP is calculated differently for Intel and AMD, usually to make Intel look better. It makes it harder to compare because hardware components are going to be different (e.g. different mobo, different memory, etc) but they should measure wattage out the wall.

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…

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

Can you recommend a NUC-like computer?

Something easy to carry around, to LAN, ideally with PCIe slots or an NVIDIA GPU

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…

> 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 you're reading this reply, you probably automatically executed `hn.js`. Are you _sure_ you know what it does? Unless you're browsing the web with Javascript completely disabled, and you also don't have any applications that automatically update…

If I should disable hyperthreading because of a hypothetical risk from an experimental proof of concept, shouldn't I also throw my PC into a dumpster because I don't know if the microcontroller controlling my LCD isn't also amplifying and Van Eck'ing my desktop to Chinese and Russian superspies waiting in a van outside?

After all, I'm not _SURE_ I know what it's doing.

Perhaps you don't particularly care about that risk, or you don't feel the risk is plausible enough to warrant the loss of one's computer, which is fair, but the risk is there nonetheless.

Why would a l33t haxxor waste their time on an esoteric and academic attack when they can just get their victim to click on something?

Mind sharing the brand/model?

https://www.amazon.com/gp/product/B086K3NFQQ/ref=ppx_yo_dt_b... 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.

I'd love to see a comparison between this and a $3000 Macbook Pro.

Plus, look at all those ports that Apple will never give you!

Thanks for the link, this might be my new laptop.

These mobile APUs are amazing. Especially when combined with a GPU. It would be really nice to be able to use these in a standard ATX motherboard because it would make the perfect home server CPU.

I share your interest for a silent yet powerful homeserver.

Unfortunately, there doesn't seem to be any desktop motherboards for mobile zen2 yet.

Too bad. I would even settle on a NUC.

Mini-ATX FF too big? If not, something like this: https://pcpartpicker.com/user/spety/saved/#view=QR7ZZL

(disclaimer, double check my research especially clearances for the cooler if you move forward :))

LinusTechTips recently took a look at a gaming laptop with the same APU and were super impressed with its Intel-scorching performance: https://www.youtube.com/watch?v=ZYqG31V4qtA

The laptop from LTT and this article is the same.
