Re: Where can I buy a Ryzen box?
They're mainly differentiated by the number of memory channels. Ryzen has 2, Threadripper has 4, and EPYC has 8. And secondarily whether there's a GPU built-in or not... which is only the APUs (the G parts), and presumably also the laptop 'U' parts that just came out. -Matt On Tue, Sep 11, 2018 at 6:14 AM Gerald Henriksen wrote: > On Tue, 11 Sep 2018 04:25:34 -0400, you wrote: > > >Is the APU part of the CPU or a separate chip?

Current "main" AMD chips - not mobile chips - basically break down to 4 families: 1) Threadripper - no APU 2) Ryzen - no APU 3) Ryzen with APU (aka Raven Ridge) 4) Epyc - server / datacenter chips It is unfortunate that AMD hasn't (at least from my casual glances) differentiated the Ryzen lines better than just appending a G onto the model number. It appears that currently the only Ryzen that come with the APU are the Ryzen 5-2400G and 3-2200G.

If you're not experienced with building machines, and don't intend to build more machines in the future, and you want to avoid incompatible configurations, then it's worth it.

Is the APU part of the CPU or a separate chip? Does the Threadripper come with an APU? Pierre -- ve ka'a ro klaji la .romas. se jmaji

CUDA is an Nvidia only technology and is only supported on Linux, Windows and macOS. For unknown reasons they apparently don't enable CUDA in the FreeBSD binary drivers so porting those won't help. OpenCL would depend on if that has been ported to Dragonfly or not, but it at least in theory can work with the AMD open source drivers, Intel drivers, and on the CPU. >Michael Neumann told me off-list that DFly doesn't support the built-in GPU of >the Ryzen.

The Ryzen with APU (Raven Ridge codename) is likely just too new having only been released in February and even as late as May there were still a lot of stability issues on Linux (when using the APU). So without Dragonfly support for the APU you would need a separate, supported video card in order to get anything other than perhaps text. Given the lack of Raven Ridge support you may want to consider pricing out getting a plain Ryzen CPU + separate GPU, may either save you money or allow to get a better GPU for the same money unless you specifically want the ability to drop back to the APU in the future if the drivers get ported to Dragonfly.

Re: Where can I buy a Ryzen box?
If you want to use the GPU for computation you may have to run Linux. In fact, you probably would have to. I usually just buy the parts on Amazon or NewEgg, and throw the computer together, but if you don't have experience doing that sort of thing its easy to get the wrong bits. -Matt On Mon, Sep 10, 2018 at 1:14 AM Jasse Jansson wrote: > Might depend on where you live. > It's not hard to build your new computers yourself, with the added > benefit that you get them exacly as you want them. > Another solution is to ask a local computer shop to build them for you. > > On 10/09/2018 00:57, Pierre Abbat wrote: > > I'm thinking of getting some new computers in a few months: > > * A System 76 Leopard, with lots of cores and GPU, but not Ryzen > > * A Ryzen box, with GPU for computation, running DragonFly > > * A few lesser boxes with other OSes. > > I doubt that anyone sells Ryzen boxes preloaded with DragonFly, so I'm > trying > > to find a Ryzen box without an operating system.

Re: Where can I buy a Ryzen box?
Might depend on where you live. It's not hard to build your new computers yourself, with the added benefit that you get them exacly as you want them. Another solution is to ask a local computer shop to build them for you.

Where can I buy a Ryzen box?
I'm thinking of getting some new computers in a few months: * A System 76 Leopard, with lots of cores and GPU, but not Ryzen * A Ryzen box, with GPU for computation, running DragonFly * A few lesser boxes with other OSes. I doubt that anyone sells Ryzen boxes preloaded with DragonFly, so I'm trying to find a Ryzen box without an operating system. But googling "ryzen no operating system" brings up computers that have Ryzen and an operating system, but no something else. Where do you suggest I look?
