Earlier today, we highlighted a leaked roadmap from VR-Zone detailing Intel's plans for its mobile Ivy Bridge processors set to debut in April and May of next year.

One detail of the report that bears special attention is the fact that the Ivy Bridge platform, both mobile and desktop, will support up to three independent displays, with one of those displays being an internal one.
While we're talking about graphics, as with the desktop Ivy Bridge processors, the mobile processors also support up to three independent displays, although one of these will be the built in display in the notebook, but hopefully we'll see notebooks with a DisplayPort connector as standard come next year.
The current Sandy Bridge platform is only capable of supporting two independent displays, limiting the MacBook Air to one external display. Similarly, the 13-inch MacBook Pro can only drive two external displays by turning off its internal display.

More powerful machines such as the larger MacBook Pro models can currently drive two external displays in addition to the internal one due to their inclusion of discrete graphics chips paired with the Sandy Bridge platform. But with Ivy Bridge opening the door to direct support for up to three displays via the Intel HD 4000 integrated graphics, even owners of smaller machines like the MacBook Air will have the option of significantly expanding their screen real estate by connecting to two external displays.

Curious to see if Ivy Bridge & the 3D transistor will be capable of driving a big external display and rendering out 3D models, or if it's increased performance just enough to give a slight bump, while focusing on reducing load everywhere else...

Honestly the air barely manages to drive a TB display, I don't even want to imagine two of them... What a torture.

My MacBook Air happily runs two displays (internal + external). Would love to have it running two external displays and shut the lid, but it doesn't seem to have the ports.

The current AMD graphics chips in Macs already support at least 4 displays, but it's Thunderbolt that is crippling.

Actually it has more to do with the number of PCIe channels given by the Sandy bridge platform.

No, Thunderbolt has half the video bandwidth as DisplayPort 1.2, over which these chips support upto 6 displays.

If it proves to be feasible on the overall system constraints, then this sounds awesome!!!

Interesting. I know a lot of folks were returning computers and canceling orders over rumors of Ivy Bridge, but I knew from past experience it wasn't going to come until the May/June timeframe (if not later).

As far as the Air goes, for the average user I don't see any great benefits when you compare the current specs to Ivy Bridge. Greater graphics performance, sure...but I'd wager most using an Air aren't gamers, and serious pro users would be on the pro line by default. The 17w power rating is identical to the current model, so I imagine the battery life between the two will be quite similar.

Definitely correct me if I'm off-base on any of this.

What do you mean it barely drives a TB display? No issues here, and the video quality is excellent? You got a lemon, maybe?

The forums need to realize that Ivy Bridge is a GPU upgrade.

In fact I'm not sure why it isn't stressed more. The CPU isn't benefiting from the process shrink all that much other than the clock gets turned up. The GPU however has been heavily rework with Ivy Bridge. It will be very interesting to see what the actual performance encumbers are under Mac OS, but I suspect more will be pleased than disappointed.

Great for a laptop I guess, but a Desktop PC can support up to 24 displays at once using 4 graphics card running in Crossfire mode..

I hope we also see Crossfire & SLI support, I'm not talking only about being able to use multi-displays but being able to get scalable performance with more then one graphics cards.. On the PC side Crossfire & SLI have been around for ages..

@$MacUser$: Two identical posts in two threads. What are you pushing?

You don't seem to be wrong, but can't see a reason for posting the same thing twice?

"Torture"?? Really? By what basis have you concluded this? Personal experience?

My MBA is works great with my 27" Thunderbolt display. On top of that, It's running Windows7 via VMware on a second MissionControl desktop.

It's running great on my machine. Please, enlighten all of us on the EXACT setup you are using to come to such a conclusion. I suspect you have none of it.
