They've been perfectly consistent in everything I've seen. No capitalisation. Not a name.

To you, perhaps. I find it interesting.

Don't then.

Well, a bit tangential, but yes, they sound very good.

Doffing cap to ARM Cambridge.


Yep M1 low power draw tightly integrated with Apple apps performance is something else.

Max has some informative comparisons
https://m.youtube.com/watch?v=59gAjXT7qyw
M1 mini 15W Vs 200w total i7 6core mini 2019 with external gpu AMD 5700xt (Nvidia rtx2070 similar).

Performance pretty much same.

Bonkers.

Environmental reasons, Utility bill reasons : no brainer

LP + FCP + Lightroom + some iPad OS apps : Im good to go.


:::::


As for whether 8GB or 16GB : just go 16GB so swap file on SSD is kept to minimum usage.

M1 iMac Pro may get 2*M1 with who knows how much RAM.

Apple apparently reserved 3nm with TSMC for M2 in 2022 maybe .


:::::


I ported over to AMD Ryzen in 2018 was a no brainer .

Ryzen Desktop Laptop, Workstation Threadripper, Server Epyc.

I will still keep a Touchscreen AMD Ryzen 4700U laptop also a 15W 8Core with Vega11 graphics.

There's handheld AMD Ryzen gaming consoles eg SmachZ https://www.smachz.com/ they say is the "Most powerful handheld console"

Now if Apple were to make M1 handheld gaming console holy smokes batman.


:::::


Big Sur(veillance) will Survey my muzak making video photo editing. It doesn't matter to me.

I still have my 2010 Mbp with Snow Leopard on a partition to undertake necessary internet things.


::::::


As for ARM Vs x86 ; RISC Vs CISC; 5nm M1 Vs 7nm AMD Vs 14nm intel
Thre's enough YouTube videos.

So this may be some bad news in general for seeing arm based DAW ports quickly:

Apple says that plugins of a different architecture cannot be loaded into a process, this is not quite true as Intel Audio Units can be loaded into an Arm process.

VST2 and VST3 Intel plugins cannot be loaded into an Arm process though.

Apples advice is to host all your Intel plugins in a separate XPC process and communicate with that process from your main process.

Might hold things up a bit!

desmond wrote:One question, which I was planning on researching - I'm not sure what the current ports on those machines are, but on my MBP, I have Thunderbolt (1) ports, and because the cables have chips in them, they (annoyingly) generate quite a lot of heat when plugged in (which contributes to heating the computer up as well).

Do the ports in modern machines still generate heat like this? Or do they use a different tech and stay cool like say a regular USB cable?

Well, FWIW i have plugged into one of the TB3 ports on my iMac Pro a TB3 -> TB2 adapter, leading to an LG TB2 monitor which in turn is daisy chained to an Apollo 8 and then an Apollo Silverface. The cables at the TB3 end are just discernibly warm. In fact none of the cables run at any real temperature.

Two of the other TB3 ports I'm actually using as USB 3.1 (slapped wrist, USB 3.2, of course) and the fourth is currently unoccupied.

I've had my iMac pro for 2.5 years now and expect it to last me quite few more. By the time I need to give it up I wouldn't be too surprised if Apple are considering changing their CPU architecture again! After all they have quite a lot of form in this area. So this discussion is interesting but academic for me.

The latest "M1X" (unconfirmed) leaks suggest the version of the chip likely coming for the new form factor Macbook Pros in 2021 will be 12-core - ie, they'll have 8 performance cores, and 4 high-efficiency cores - so, around double the performance we're seeing in the current M1 chips for the currently available machines, which have 4 of each type of core.

Just having a nose through that, thanks.

It's all looking very interesting, and I'm definitely glad I decided to delay ordering a Mac Mini.

Appreciated


TLDR :


M1 family are optimised for certain tasks apps that's why they perform brilliantly for these tasks apps :
easier to make ARM for specific tasks apps
eg 128 cores Altra Max ARM specifically made for the cloud.

Whilst M1 family will be cr*p to average at tasks apps its not optimised for.

AMD Intel are general purpose covering as many tasks apps as possible thus obviously they are jack of .....
alongiside their architecture requiring Higher GHz a LOT MORE Wattage compared to M1.

M1 RISC architecture has 8 instruction decoders compared max 4 on AMD intel CISC :
thus 2x as many instructions processed by M1.
Apple can add even more decoders to M1.

M1 Re Order Buffer : ROB is 3x size of AMD intel
Holding 3x as many instructions :
thus M1 runs faster at lower GHz because it's 3x ROB size can be far more quickly filled up with far more micro op instructions.


:::::

I'm only gonna use Mac Mini M1 for what it's optimised for : muzik making video editing photo editing.

I might just wait to see price of M1X Mac's.

:::::


In my view AMD latest current 5000 series Ryzen and forthcoming Threadripper being so far ahead of intel
along with performance better than M1 for tasks apps M1 optimised for,
actually makes sense for Apple to put 5000 AMD Ryzen or forthcoming Threadripper into forthcoming Mac Pro with its large fans large cpu heatsink.

I didn't see any thermal test there, so considering all apple computers thermal throttle save for the chees grater (although i'm not totally sure about the minis...), this might not be a comparison between the two chips, but rather between the Apple units.

Comparisons between M1 and AMD/Intel need to be done in an adequate AMD/Intel environment.

I'm not knocking M1 (i think it looks excellent so far), but this comparion is most likely between old mac mini and new mac mini, not between i7 and M1.

The main problem I have found so far with the M1 is "Big Sur" or as I have nicknamed it "you piece of shit".

I see the new Minis only have two Tbolt ports compared to the previous generation's four. Bit mean, that.

Edit: apparently you'll be able to use Tbolt 4 hubs with the new ports so that goes a bit to alleviating the lack of ports. Want to bet you'll need a second mortgage to buy one?

This is because all these new machines are entry level machines, and use the M1, which at this time has limited connectivity support (two channels which support two ports).

The next variant of the chip (likely the "M1X" but we'll see) will support more I/O (and ram), and these will be used in Macbook Pros, iMacs, and the higher end Mac Mini to replace the remaining Intel one.

So if you need more connectivity, you should avoid this first generation of M1-machines, as they are only the *low-end* models.
