[andy patterson] “I was wondering about the future of the Mac Mini.”
It’s in every future iPhone user’s pocket.

The iMacPro won’t have a Radeon RX580 or similar they are waiting for the new cards to drop from AMD Radeon Vega,
“This is where the AMD Vega GPU architecture comes in, aiming to jump in at the high-end and providing the Radeon faithful with a serious GTX 1080 Ti contender.”
I’m also excited about the eGPU solutions which Apple talked about, mainly for the Macbook Pros but they’ll work the same for the iMac Pros as well, so potentially you could have a Vega as a main discrete dGPU and another Vega in an enclosure doing more computations, coupled that with:
“Infinity Fabric allows us to join different engines together on a die much easier than before,” Koduri explained. “As well it enables some really low latency and high-bandwidth interconnects. This is important to tie together our different IPs (and partner IPs) together efficiently and quickly. It forms the basis of all of our future ASIC designs. We haven’t mentioned any multi GPU designs on a single ASIC like Epyc, but the capability is possible with Infinity Fabric.”

Good break down of the iMac Pro:
https://www.provideocoalition.com/new-imac-pro-worth-probably/
One question I have (not answered in the article) is whether the Thunderbolt ports and 10GigE port are all separate or are they shared internally. For example, the current 2013 Mac Pros have six TB ports, but only 3 buses. You lose one if you have 2 displays. So if the new iMac Pro has 4 or 5 separate buses, that already beats the 2013 MP in throughput by a long shot.

Another thought on the iMP is that because this is using a Xeon processor, you do lose the advantage of accelerated H264 encoding that the Core-i chips offer. So in theory, encoding MP4 and other H264 files might actually be slower on this machine than current fully-loaded iMacs and MBPs.

That is a possible issue. OTOH if you lose 3x performance due to no Quick Sync but gain 4x from 18 cores, it still might be faster. There are also other possibilities — see my comments in this post: https://forums.creativecow.net/thread/335/95701#95782

If you are making that many mp4s a day, then yes, the iMac Pro may be “slower”. May be. But if that’s the case, you’d have a dedicated machine cranking quicksync mp4s all day every day tethered to your new 10Gb storage.
I can’t imagine slowing down the entirety of editing/rendering on a lesser machine just so I can make a review copy in 3 minutes instead of 5.

The lesson I learned in 2015 was NEVER waste time “imagining” what hardware might do.
Wait for it to ship and test what it ACTUALLY does.
A few years back I’d read 1000 times that a big desktop level machine was required to do serious daily editing for money.
That wisdom was totally and utterly wrong – yet years later, people are still parroting it.
People working only in desktop machines missed the gap closing in mobile vs desktop processor performance along with the development of modern proxy workflows.Basically, the ground had shifted.
When the iMacPro -and later whatever MacPro replacement arrives – that’s when it’s time to assess the validity of the workflows that it will enable..
When they can be tested in the real world.
Speculation is fun, but often woefully wrong when it crashes head on into reality.
My 2 cents.

There is no shortage of BS on the internet. Six years ago many FCPX users claimed you need an $8500.00 workstation to edit native AVCHD using Premiere Pro. A few years ago it changed to you need a $8500.00 workstation to edit 4K using premiere Pro. As I have stated there is a lot of BS on the internet.
[Bill Davis] “That wisdom was totally and utterly wrong – yet years later, people are still parroting it.

Some people want to edit 4K, 6K and 8K at full resolution using camera raw files and other native formats. For that you probably do need an $8500.00 desktop computer.
