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.

A common use case includes video transcoding and the ability to offload this to hardware makes the NUC a good choice.

I’d love a good AMD option, but for the size and price, I can’t find anything that will transcode as efficiently.

The new Ghost Canyon NUCs look excellent, but I assume pricing will be eye watering. They are also much larger. https://www.anandtech.com/show/15720/intel-ghost-canyon-nuc9...

What would you use the GPU for in a home server?

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.

Intel's is roughly "the thermal dissipation required to maintain base clock speeds indefinitely without thermal throttling".

AMD's is roughly "the thermal dissipation required for all-core turbo indefinitely".

In recent generations (since AMD's Zen architecture), AMD is much closer in testing to their published numbers than Intel is.

It is important to note that this is a thermal specification, rather than a power consumption specification. There are processors that exist which can hit their performance numbers without needing any thermal solution, and as such would have an "honest" TDP of 0, despite having a >0 power draw from the wall.

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.

Passmark results on it. https://i.imgur.com/RkdNpC5.png https://i.imgur.com/i8WLsFV.png

CPU shows 20,349. The only other Windows box I have is an old first gen threadripper 1950x, which scores around 29,373.

She needs to finish downloading the Creative Cloud kit before I see how it stacks up to some older i9 macs.

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... ).

Here's a setup which takes advantage of TB3 on the desktop. I think this is a compelling setup, though not something I aspire to.

I believe so. https://www.asus.com/us/Laptops/ASUS-TUF-Gaming-A15 Is what we have on route. No SD slot... but most of the other ports one might need.

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.

SD Card slot,for transferring files from her camera. It does have room for an extra m.2 drive. I've not opened the back yet... those parts/packages have not shown up yet.

I do like that setup but it doesn't actually need TB3, as a follow-up video from LTT showed: https://www.youtube.com/watch?v=jvzeZCZluJ0

At the turbo clock the i9-10900F is 5GHz vs. 4.3Ghz for Ryzen 9 4900HS. At the base clock the i9-10900F is 2.8GHz vs. 3GHz for the Ryzen 9 4900HS. Basically implies that Ryzen has better performance per watt, which doesn't affect absolute performance until you exhaust the power budget and have to lower the clock speed, i.e. use all the cores instead of just one. edit: 4900HS, not 4900H

Small nit but the comparison here is against the 4900HS 4900H: 4.4ghz boost, 3.3ghz base 4900HS: 4.3ghz boost, 3.0ghz base With the non-S variant being the more power hungry one with an up to 54W TDP vs. the S's 35W TDP.

Interestingly even the faster 4900H has a lower TDP than the 65W i9-10900F.
