Macrumors: New Mac Pro: Simultaneous Real-Time 4K Effect Rendering, +900MB/s Read/Write
http://www.macrumors.com/2013/12/20/...mbs-readwrite/
Uh, thanks, but that still doesn't directly answer my question, nor confirm what I want to know. And there's too much conflicting info out there elsewhere. Your second link doesn't have anything to do with a new Mac Pro, just a MacBook Pro and in the case of the MBP, the answer is NO, it doesn't support this (MST via Thunderbolt2 to DisplayPort 1.2)...
Having previously owned a Sharp PN-K321, the DisplayPort stream settings had to be changed to enable 60Hz, even at resolutions less than UHD.
Having tried to seek additional clarification, the best I could get from Apple's support is this document, which is also linked in your second link you had. Unfortunately, it's worthless… http://support.apple.com/kb/HT5219
I have to retract some previous Statements on Red Giant and AE. After testing some with a clients work the Red Giant FX are threading across all 24 threads on this 12 Core single Xeon. BTW PNG on Windows is not threading well at all though on export so avoid that when possible. Other Quciktime codecs/formats are threading well. PNG is threading ok in OSX.
The new Mac Pro is discussed in both links so you must not have actually read what I put there. It says Mac Pro (Late 2013). You connect a single miniDP2DP cable from one of the Thunderbolt ports to the Sharp or Asus display and set those monitors into the stream mode to get 4K @ 60hz on those monitors using two MST streams from the GPU. It even says as much in the user manuals for the monitors, which you should be familiar with since you repeatedly claim to have owned the Sharp for a few days. The next generation of monitors, including the probable Apple Cinema Display as well as the updated Sharp display coming next year will use HBR and that will give you a full 4K @ 60hz with 10-bit color signal. Once those monitors are available, Apple will enable HBR in the drivers and software and you'll get a single cable with a single 4K @ 60hz video signal through the DisplayPort though straight Thunderbolt will be your choice since it will be offered on those monitors in addition to DisplayPort using HBR.

Atto and Decklink work on my Magma on my existing Mac Book Pro. I wonder if I will see any performance gains vis-a-vis Read/Write from RAID due to Thunderbolt 2 ports on the New Mac Pro. Hopefully Magma will upgrade the enclosure soon.
I have been going back and forth with Colorfront about Express Dailies and they have assured significant performance enhancement over 12 Core 2012 Mac Pro. I have asked them about processing Dragon r3ds without the card.
"ExD now uses OpenCL instead of CUDA to support the New Mac Pro. Expect FAST Debayer and image processing, 4K@60p RAW support."
"Anamorphic Opengate 3.4K ARRIRAW in 4K@60, in ACES with deBayer, desqueeze, color grade."
Er… Not trying to be obtuse or argumentative here, but… Got both links open and have double and triple checked. No mention of the Mac Pro in your second link, nor 60Hz in that link. See attached image. Second link only talks of MacBook Pro and only UHD/4K at 30/24 Hz. While the late 2013 MacBook Pro does support DP1.2 MST output, it does not, DOES NOT, NOT support UHD/4K at greater than 30Hz even though the GPUs in the system technically do. If something has changed with the 10.9.1 Mavericks release or latest EFI/TB2 update, someone please tell me, but it did not work as of a couple weeks ago.
I know how the monitor works. I know Apple is nice enough to include the necessary $7 cable. I'm even 90% sure it all works and runs 4K at 60Hz. This stupid link is poorly written, as most of these are, and what we want to know is obfuscated by a complete lack of necessary detail. It talks of using a 4K monitor. It talks of 60Hz via multi stream mode on the monitor. It does not just come right out and say 4K @ 60Hz. It's not helpful because we have to go into the display settings and activate MST to get anything over 1080p 60Hz on these displays. I want to read it that way, as if it does indeed output 4K @ 60Hz, but I've had too much experience with this stuff over the years to ever make such an assumption. Compound that with the initial reports I've seen/read so far where people say the nMP does not support 60Hz at 4K via TB2. So then I have to ask, do these people not know how to configure the monitor? Do they know and it actually doesn't work? I just want someone with both the system and the display to confirm it. A friend of mine has the ASUS 4K PQ321Q, if either of us had a Mac Pro here, it would be the first thing we'd try as we set it up.You connect a single miniDP2DP cable from one of the Thunderbolt ports to the Sharp or Asus display and set those monitors into the stream mode to get 4K @ 60hz on those monitors using two MST streams from the GPU. It even says as much in the user manuals for the monitors, which you should be familiar with since you repeatedly claim to have owned the Sharp for a few days.
Call me paranoid, but I just want the actual confirmation. Mostly because I have tons of people asking me which 4K display to get and which one does what and how this Sharp (or ASUS or Dell) will work with the nMP and I can't give them a 100% definitive answer.
I sent back my Sharp PN-K321 because it had terrible light leakage all across the bottom of the screen, nVidia drivers at the time struggled with the dual input format and I had paid $4750 for it and felt that price wasn't acceptable with the light leakage mostly. I knew the driver issue would be sorted and nVidia already stated they were on it before I sent the monitor back. Light leaks, mostly on the bottom edge, seemed to be a common problem early on with these displays. My friend's ASUS doesn't exhibit any of that. I'd buy one of these displays again if they slashed another $1K off the price, probably the Dell model because of the additional controls and LUT support. Not going to spend $3K+ for one at this point when updated or alternative models are only a few months away.
I'm operating on the same impressions/ assumptions. I think we're going to see a flood of 4K goodness including HDMI 2.0 and Thunderbolt-2 connectivity at CES.The next generation of monitors, including the probable Apple Cinema Display as well as the updated Sharp display coming next year will use HBR and that will give you a full 4K @ 60hz with 10-bit color signal. Once those monitors are available, Apple will enable HBR in the drivers and software and you'll get a single cable with a single 4K @ 60hz video signal through the DisplayPort though straight Thunderbolt will be your choice since it will be offered on those monitors in addition to DisplayPort using HBR.
Something strange is up. Click on this PDF:
It's maybe a cache issue Jeff. I made this PDF from Apple's site.
