Yes TB3 is still a lot faster as I said. Some QNAP NAS implements both. But I don't understand, you say you are not getting TB3 speeds because of QNAP specific implementation ?

A switch is always better.

Perhaps I didn't explain what I meant properly, sorry, mind on other things.

There's is a difference between connecting say a Thunderbolt 3 drive like say a Samsung X5 and some devices that run over Thunderbolt 3 as a network. Networking over Thunderbolt 3 is 10Gb. To see what I mean have a look here. Connecto two Macs over TB3 and you'll get an IP address on each i/f, and 10Gbe throughput.

It's the same connecting a TB3 Mac to the QNAP I have. Performance I get is pretty much exactly the same as 10Gbe.

If you have a look at the TB3 specs for example - a summary is here - if you look at 'Thunderbolt Networking' you'll see it's only 10Gbe. So of course it's tons faster than 1Gbe - it's the same as 10Gbe if it's running over the TB3 network stack. Also here. Important bit being:

In all of its forms, Thunderbolt supports Ethernet networking protocols. This not only means you can use a Thunderbolt to Ethernet adapter cable to connect to a 10 Gb Ethernet network, but also that you can use just a Thunderbolt cable to connect two computers at up to 10 Gbs in a super-fast peer-to-peer network.

No. I'm getting TB3 Network Speds as per the TB3 specification for networking.

Aaaanway, I'm boring myself and forgot what point I was originally trying to make 😆
 
VERGE article mentioned that the hardware for the speaker is identical and the only reason why sound is better is because T2 chip processes it better. So makes me wonder how much better it is with the same hardware

I noticed this on the press comms. "... higher fidelity speakers, and studio-quality mics..." would be interesting to find out what this means in real terms. Hopefully the reviews at the end of the week test and pick this up.
 
Yeah, I think that 21.5 will be replaced with the redesigned AS 24. Makes sense as that is low performance computer to start with. Regardless, I hope this 27" is redesigned internally because they had all these years to make it better inside and 2017 iMac Pro certainly showed them what works so this better have some elements from iMac Pro.
No fusion drive = more space = more room to play with.
If its another jet engine with crippled performance then " no thank you"

But sure, give us $500 glass.


The 21.5" didn't get a chip update. I could see the 24" silicon replacing that one and be sold alongside the updated 27" intel.

Ok thanks for explanation.

I thought that on these NAS it was full 40gbps when connected over Thunderbolt 3. I didn't think it was related in any way to networking, but directly between Thunderbolt controllers on each side. See https://www.qnap.com/solution/thunderbolt3-nas/en/ They say bi-directional 20gbps.

Not for NAS, no, they run Ethernet over TB3. I imagine the DAS ones will use 40Gbps? Not sure, I don't have any of those. Would be nice though!

I can edit 4K over the TB3 10Gbe connection well enough, and copying 200GB virtualisation sets is actually possible without kicking it off and going for lunch. You can see the performance of the QNAP here. Wandering off topic a bit :) Both my iMac Pro and my Mac Mini are connected to that over TB3 at the minute too - not sure you could do that with DAS anyway?
 
As a side note it's boiling my underpants that the we have ordered the new i9s with 1Gbe.

I'll stick with my iMac Pro anyway as I've gotten used to the 4 TB3 ports. 5K screen, Samsung X5, TB hub, connection to Mac Mini. Admittedly could drop the connection to the Mac Mini as it's also on the 10Gbe n/w.

I could live with 2 Thunderbolt.

Both for connecting one display each (3 display setup).

10 gbps has it's own port.

Everything else on normal USB ... Not bad. I would have liked all USB-C ports, but it's fine.
 
Went with:
3.6 10-Core I9
32 GB Ram
1TB SSD
Radeon Pro 5700XT with 16GB GDDR
10 Gigabit Ethernet
Standard Glass

not expected to deliver until Aug 18th-20th though. I got a magic track pad 2 but must not have seen that you can upgrade the keyboard to one with a number pad. Not a huge deal and I'll probably just buy the new logi keyboard anyways as I have and love the logi MX master 3 for drafting.

Concerned with what others have said about cooling, but other than that I'm pretty happy with this update. Especially 10 Gigabit ethernet, I'm pretty sure that can solve some very long print job's for me. Most excited about the GPU. For what I do in my work flow, it's a big update. Totally bummed about the lack of a physical update but alas, I do in fact need a machine now, and this just means I'll update my laptop first to Apple silicon in a couple years.
 
Wouldn't it be nice to get a TB3 hub that gives you multiple TB3 ports? Couple I have have a pass-through port but that's it.
 
Cant wait to pair this imac with 2 x XDR displays :eek:

Wouldn't that be nice... Looks possible with the 5700?

Simultaneously supports full native resolution on the built-in display at 1 billion colours and:

One 6016x3384 (6K) external display at 60Hz with support for 1 billion colours, or

Two 6016x3384 (6K) external displays at 60Hz with support for 1 billion colours (requires Radeon Pro 5700 or Radeon Pro 5700 XT), or

One 5120x2880 (5K) external display at 60Hz with support for 1 billion colours, or

Two 3840x2160 (4K UHD) external displays at 60Hz with support for 1 billion colours, or

Two 4096x2304 (4K) external displays at 60Hz with support for millions of colours

Probably. But the displays I'm eventually targeting are Dell U2720Q USB-C. I can directly plug them into the Thunderbolt port. I don't think I need Thunderbolt for anything else.

Yup 2 XDRs with the 5700xt
 
Just bought one guys!

3,6‑GHz 10‑core Intel Core i9
8 GB 2666‑MHz DDR4‑memory
Radeon Pro 5700 XT with 16 GB GDDR6
1 TB SSD
Gigabit Ethernet

I never thought I would ever buy a computer with two times as much VRAM as RAM 😀

And thanks everyone for making the wait more bearable 😊
 
Got an email that I should get mine Thursday! Ordered the $2299 model, and my own RAM.

I've two Ultrafine 5K units. Weirdly, if they're both plugged in to the iMP I get a lag on one of the screens. Never really got to the bottom of it but if it's plugged into the TB3 hub it works just fine.

Don't forget to upgrade the system RAM or your VRAM will be totally useless :p

Was never really a fan of the das keyboard.

Do you have the hardcore one with blank keys ?
