[Walter Soyka] “My back-of-the-napkin math says that a 6144×3160 image with 3 channels (RGB) at 16 bits per channel is about 888 Mb or 112 MB.
With a transfer speed of 20 Gbps, you could move 23 of these frames per second.”
That’s only uplink right? I don’t think TB2 maintains 20 Gbps up and down simultaneously, if it doesn’t then is 11.5 fps

Of course they’re going to say that, they’re not going to discard the whole Mac user base, and while you can run that card in TB, you’re never going to get the same performance you can get running on a fast PCI bus.
I’d recommend give this a listen where they talk about the limitation and bottlenecks that may occur running a Red Rocket X in a NMP

I’ll go with the tower, I need to upgrade my 2009 Mac Pro, and I’m thinking I’ll go for a 2010/12 12 core, I think that tower has lots of leg still, specially when considering that the NMP’s power is in the graphic cards, and those cards are actually cheaper when bought as pci-e cards, they are listed as AMD R9 280x, so they can be installed in a legacy Mac Pro as well, although for the moment I’ll stay with NVidia.
I think for the future I’ll go NMP if I have no other choice, but I’ll definitely start moving to HP with a Z820, I’ll aim for Linux for most pro apps, and Mac for everyday tasks, which in that case I’ll probably go iMac instead of NMP.

[Jeremy Garchow] “But I do think that we have to take a look at what is truly possible instead of spouting theoretical speed stats.”
It’s not theoretical stats, it’s math, you have a device that requires a transfer speed of 80gbps and you put it on one that transfers at 10. Now,I don’t know of the top of my head the speed of the Red Rocket, but with 5K and Dragon, Red Rocket X is what’s going to be, and that needs speed. The only way I can see that working in a TB environment is if someone figures out how to raid TB ports, meaning you get 4 TB2 ports to act as one giving you 80gpbs.

[Jeremy Garchow] “A thunderbolt based PCIe extender, just like all PCIe cards.”
Serioulsy??? Didn’t you read anything I just said? Thunderbolt is 4X slower than PCI-e X16!!! You cant plug high performance cards like a RED Rocket X in it

[Jeremy Garchow] “So, the verdict is that on older MacPros you needed a RedRocket card, and the same is true on new MacPros? What PC’s can debayer Red 4k in real time, and how much do they cost? Do they cost more than a Tube with a Rocket card? How about a laptop and a Rocket card? How about the lowest end Tube and a rocket card”
Where are you going to plug that card, specially the new Red Recket X coming? You need a computer with PCI-e x16 slots…, and if you think you can get a thunderbolt to pci-e adapter you can, but thunderbolt 2 speed limit is 20 gbps, PCI-e x16 is 80, so with a thunderbolt 2 to pci-e you can use but at a quarter of its capabilities

[Jeremy Garchow] “What did you expect and how were those expectations not met? How do you go from wow to meh in 60 seconds? Just curious.”
Form factor, of course you can’t get a good test in the Apple Store, I guess I bought into the new form hype, but after a minute next to it, it really felt like a trash can, hard to explain…
But I’ve been following up the reviews, specially the one that did the guys at liftgammagain, and the conclusion seems to be that it barely outperform a 2012 12 core, if it does at all, and RED 4K debayering in real time is a myth, you still a RED Rocket card, and good luck with this new mac, PCI-e over thunderbolt has a cap on the speed as well, so it’s not the perfect solution, or the “Most expandable Mac ever” as Tim Cook said. -
I gotta say I’m getting more and more disappointed with the new Mac Pro, I was playing with one at the Apple Store the other day, my first impression was WOW!!!, a minute after I was meh…
I’m starting to get really pissed at Apple’s design over function direction, I can’t believe I got to a point where a HP Z820 looks incredible sexy to me, if only they’d open OS X…

on #1, I’m not sure, but it seems you’re using a computer monitor right? If that’s so, most likely the problem is the refresh rate of the monitor is conflicting with the fps video speed. I would try to switch to other refresh rates, but that’s a problem I used to have when working in Smoke through DVI port before they supported the blackmagic card.

[Rick Turners] “Trust me I know it’s all about the artist but if resolve can do everything baselight can then what is filmlights justification for the higher price point? I don’t see anything on the filmlight website that has any distinction other then price.”
That’s one of the biggest misconceptions we’re having these days when it comes to Resolve. I don’t know how much a Baselight is today, but before Blackmagic acquired DaVinci, Resolve used to cost around $250K, which it was probably head to head to a Baselight in those days, and this is not so long ago. Now it’s 250 times cheaper and 250 times better, yet the market perception it’s getting because of its price (or non price) is that it’s aimed at prosumers.
