(As someone who buys Apple since 25+ years) Apple pricing has never been cost driven, but value and brand driven.

"Apple: Does more, costs less"

Why am I being downvoted for exactly quoting apple marketing from the past?

I do have an AMD Hackintosh, I don't see any reason you wouldn't be able to use these as a dev Hackintosh machine. It's gorgeously fast with my Ryzen 2700x, eats compilation time like no one's business and it's stable. And it's something around 1/4th the price of the same horsepower from native Intel Macs. I can't imagine the cost delta of a EPYC Rome Hackintosh to its Intel counterpart. It's not like I cheaped out e…

How was it getting things working on your AMD hackintosh? I’m very, very tempted to switch to AMD when the new Ryzen chips land but obviously want to be able to run macOS.

I would be cautious about recommending hackintosh to the general public, but for any software guy or gal, it’s a walk in the park. You might need to debug some driver stuff but ultimately there is a possible, perfect state where everything works, given some prior preparation. Same for AMD.

I clearly mentioned it is an XEON 8280 _QS_. You can buy from ebay.

Looking this up it seems like Engineering and Qualification samples are loaned by Intel, so the people selling them don't actually have the legal right to do that. They also might have other issues and limitations because they're not the final product, and you don't have any warranty on them. That's a lot of caveats to hide behind two letters.

Indeed. Stay away from Qualification Samples... the last thing anyone should want is an Intel CPU that's even less half-baked than usual.

Did you manage to get power management working on a AMD hackintosh?

Pray tell, where are the docs for AMD hackintoshes? Running on Intel atm but the time for an upgrade is coming close.

Do you have power management (and sleep) working on amd?

How about those adobe applications? I heard that PS, Pr, or Ai need special patch to run on amd machines

I'm actually a designer, but I stopped using Adobe a very long time ago for unrelated reasons — when they switched to the subscription model. For that reason I didn't even try to run them. I do realise that might be an untenable position for someone in Hollywood since FCPX is not a match for Premiere / After Effects at that level, however, there are plenty of other things that do the job of Photoshop and Illustrator,…

FWIW, I have found Figma to be better than Sketch.

They are stuck with intel because of thunderbolt.

actually Asrock release X570 for ryzen2 with PCIE4 and thunderbolt 3 ( https://www.anandtech.com/show/14455/asrock-x570-aqua-heavie... ).

It seems they are also coming out with a Thin-ITX form factor motherboard, which up until now has been limited to Intel platforms.

Start from https://amd-osx.com/.

> Do you have power management (and sleep) working on amd?

Yes (null-power-mgmt.kext) and yes. Though mind that this is a desktop, so power mgmt. / sleep needs are much less demanding than a laptop.

Specifically, the kext works by disabling power management from within OS X. However I have a kill-a-watt and the the power from the plug varies based on the CPU load, so it seems to be behaving correctly.

That said, I would not do this on a laptop. Just buy a MacBook Pro if you need that. My hackintosh needs are strictly because Apple (until a week or two ago) just didn’t make a computer as powerful as I needed. I’ll probably just go buy a Mac Pro in the first chance.

I'm curious why they aren't charging more for it. Wouldn't that be free profit margin?

Or perhaps they are trying to hurt Intel by selling it at a price where Intel can't make a profit if they lower their prices to be competitive?

Or, maybe it has to do with trying to quickly grab market share. Maybe AWS and other purchases of servers have a somewhat fixed budget, so cheaper chips translates directly to more chips sold?

Both those explanations seem unlikely to me.

Only AMD execs truly knows but I think there might be two factors involved. They really want to attract new customers and build echo system and the second part is hard when everyone has been buying almost entirely intel. The second is their cost for such a cheap should be enormously cheaper than intel because of chiplet design. A single chip die for the intel chip is way bigger and yield and cost dramatically increases as die size gets bigger from what I read. So at same profit margin AMD chips would be cheaper and to gain the market share they are probably willing to lower their profit too so those two element adds up.
