The most cost effective way to export for MacOS

[Christoph Hart]

Yes, that's the plan.

Awesome!

@Christoph-Hart said in The most cost effective way to export for MacOS:

Yes the i9 is really something.

Any specific recommendations?

[Christoph Hart]

Yes, build a passively cooled system. I only have one case fan that goes on for a few seconds when compiling with all cores at 100%, but apart from that, it's dead silence here...

[d.healey]

@Christoph-Hart What processor and cooler/heatsink do you use?

[Christoph Hart]

i9/9900K + a custom passive system from these guys:

@Christoph-Hart Thanks. I was looking at the i9/10900 because it's TDP is 65W I was thinking it would be good for a passive system (my current system is also passive but lacks horsepower). But if the 95W CPU can also be passively cooled successfully then maybe I'll go up a level :)

is there some reason your not considering any of the AM Ryzen options? =- Just curious...

[d.healey]

@Lindon I don't know much about modern AMD CPUs. The main reason I haven't looked into them is because there is no way to disable the AMD PSP, but even with the newer Intel system's we're no longer able to disable the ME.

Do you have any recommendations for AMD CPUs? Needs to be 65-95W and have an integrated GPU.

[Lindon]

@d-healey sounds like I'm even less skilled than yourself about what makes a good CPU, all I really know is the Rayzen CPUs are (apparently) kicking butt all over the intel ones these days an "bang-for-buck"

[d.healey]

@Lindon I've just been reading up on them and they seem quite good. There's one that's just been released which has a slightly lower core count than the i9 I was looking at, but the clock speed is higher, it has AMD Graphics, and the TDP is only 35W. I'll do some more research but AMD doesn't seem like a bad choice at all.

@d-healey my question will sound silly but, what about IPP? if you have amd processors or other processor?

[Christoph Hart]

It works there too but I think I read somewhere that Intel is making them intentionally slower on foreign CPUs. Not sure if its IPP too or just their own compiler.

I might build a thread ripper rig to see what's up

[d.healey]

Seems the latest APUs are only available for OEMs :(

I've always been an Intel user, 10th gen i9 10850K (5.0 GHz overclocked for all 10 cores with a liquid cooler). I am happy with it.

But Intel has made very bad strategic mistakes lately. High price, low improvements. Intel stucked 14 nm process node architecture, even the AMD uses 7 nm for years- ARM uses 5 nm! In the past, the best Intel performance (compared to AMD) was the single core speed, but it seems like the latest AMD Ryzen cpus beats Intel for that too. Even Intel PCI Express 4.0 support come 2 years later than AMD did.

Acording to the reports, PCI Express 4.0 supported 11th gen i9 cpu doesn't seem to give great performance like it should (even on the single core performance!) And it falls the way beyond the competitors.

I think ARM will be the next winner for all in case of power usage, performance and AI technology. And of course Intel has beeing forced to be adapted to the new technology trend.

Looks like Ryzen might not be the best choice for a passive system due to power consumption - https://hattedsquirrel.net/2020/12/power-consumption-of-ryzen-5000-series-cpus/

This stuff gives me a headache.

[d.healey]

So I went with a Ryzen 5900 in the end (thanks Lindon). I'll probably switch to one of the APUs when they become available to the public. I made a semi-passive build as Christoph suggested, with an ITX motherboard and a humongous heatsink.

I've power limited (65W) and undervolted the CPU to keep things nice and cool. Idle temps are around 43C and I think I can improve on this with more tweaking. I've set the fans to only turn on when the temps are above 45, but I think I'll increase this to 50.

The graphics card uses more power than the CPU at idle and produces a fair bit of heat, so switching to an APU in the future should help with that.

@d-healey Sir, How much this Cost?
And can you Share the details of the PC?
