Title: AMD Ryzen Threadripper Post by: Andre on October 11, 2017, 06:51:40 am Hi Peter,
can you elaborate on building of an AMD Threadripper sound pc? A lot of CPU cores for reasonable price... Will XXHighEnd work with Threadripper or any other Ryzen? What are your thoughts about this topic? Thanks in advance! ;) Title: Re: AMD Ryzen Threadripper Post by: PeterSt on October 11, 2017, 12:36:33 pm Hi Andre,
There is no reason XXHighEnd will not work with the AMD. Quote A lot of CPU cores for reasonable price... True, but against the price of a high TDP (what about 180W). Quote can you elaborate on building of an AMD Threadripper sound pc? So assumed you know about our Stealth Mach II PC (http://www.phasure.com/index.php?topic=3621.0), I myself will never be able to approve that. I mean, this PC is all passively cooled, runs on a linear power supply again passively cooled and anticipates a 120W (Xeon) processor. These too come with quite some cores like (hyperthreaded) 28. This 28 core is not really comparable anymore because quite expensive, but the 20 core costs less than the Ryzen. I myself know nothing about the real performance and then mainly how it can be UNDERclocked, which is what we do with that PC (up to 300MHz if you want). And this really is to the benefit of better sound. Anyway, a completely new motherboard (to me) and I really will not be able to tell. But if someone has a gaming rig with it and a couple of 70dB fans, then he can try it out. :swoon:. Please notice that even the gaming is not about processor speed at all and only partly about the GPU (speed and setup). It is about Minimized OS and what that all further implies for way way more (gaming) speed. But what I wanted to say : now the whole PC consumes less than 30W and I can't tell in advance how that will work out with the Ryzen. If it is too hot (and/or can't be reved down) then it is byebye to the passive cooling and everything. And *that* I regard crucial. Now I hope this helps you a bit ...

So the number of cores does affect the sound quality... By the way I am actually a little bit puzzled about Mach II PC having linear power supply (which is very inefficient by the essence of Linear Power supply) and also having switching secondary power supplies already on the motherboard (unless they are manually removed) and those secondary power supplies can be very noisy (electrically).

Quote So the number of cores does affect the sound quality... 100%. Quote By the way I am actually a little bit puzzled about Mach II PC having linear power supply (which is very inefficient by the essence of Linear Power supply) Not ours, because it is only more efficient than an SMPS. That is how I deliberately said "less than 30W for the whole PC" ... and that includes the supply it self (eh, obviously but it may go unnoticed :)). Quote and also having switching secondary power supplies already on the motherboard That takes the assumption that the noise from this would influence sound. Well, maybe, but it is difficult for me to reason how to. So I use the LPS for "backfire" mains reasons. Or think about what the switcher actually does when more power is needed; it is digital behavior (and *now* you are allowed to think noise again, but towards the mains itself). Anyway, the moral is that all is a consistent whole and you can't leave out one piece of it (see my previous post). So for example : use a higher Wattage CPU and the LPS is not sufficiently powered any more. Make it larger and it will spread too much heat. Now active cooling is necessary. The active cooling consumes as well (1.2 IIRC) and it gets worse again. And ... So we travelled the other way around, until it started to work. And the base is the software. Nice eh ? Regards, Peter |
