Mostly No QuickSync

One of the most significant features of Intel's Sandy Bridge CPU is Quick Sync, the hardware assisted video transcode engine. In our review we found it to be better than any of the currently available GPU based transcoding methods and far better than just running the transcode operation on your CPU. While Quick Sync's performance/quality in the pro space is unproven, there's simply no better way of taking your existing video content and transcoding it for use on mobile devices like an iPhone or an iPad.

Given how well Quick Sync is suited for moving content between i-devices it's surprising that Apple doesn't tout it as a feature of the new 2011 MacBook Pros. Not only is Quick Sync not featured by Apple, it's not supported by any Apple application other than FaceTime.

That means iMovie and QuickTime rely on CPU based video encoding and not Quick Sync.

Apple has traditionally been very conservative with adopting new hardware features in software (ahem, TRIM). I'm worried that we may not see Quick Sync in iMovie until the 2012 version, however once the rest of the Mac lineup moves to Sandy Bridge maybe the incentive to introduce it sooner will be there.

Apple does claim support for Quick Sync in FaceTime however CPU utilization is still very high when using FaceTime HD:

Depending on available upstream bandwidth I saw between 50 and 100% CPU utilization of a single core while running FaceTime. According to Apple, FaceTime HD wasn't possible on a dual-core machine without the SNB video encoder. As to why we're seeing such high CPU utilization even with hardware accelerated encode and decode, your guess is as good as mine.

What About The 13? 6Gbps SATA

    The laptop was not constantly crashing, maybe 1-2 times per week. Had I sent it in to them nothing would have happened because they would have run their own woefully inadequate ram test. I replaced the ram and have not had any crashes since.

    HP also insisted that I reinstall vista when my led screen turned solid blue at a certain angle.

    i've been dealing with computers long enough to remember lifetime warranties being standard and dell sending replacement parts with no questions asked.

    around 2000 is when it changed and i've had to lie to tech support even when i called for large customers with tens of thousands of dell computers bought.

    my own personal experience with HP tech support for a work laptop vowed me to never buy a HP laptop again unless it's from costco or dirt cheap to where i can buy one every year and junk it without thinking twice.

    same with dell. 7 years ago i bought a $1500 laptop with the 3 year warranty. 2 years into it i find out the battery is not covered. Unlike with Apple where the entire laptop is covered and going to the genius bar doesn't mean being on hold for hours and needing a translator to talk to someone

    Huh. I've never had a problem with HP service before. I've had HP laptops ranging from the 2800T to an Elitebook 6930p to an Envy 15. In each case, there was an issue that had to be resolved, and I received prompt, accurate service, including a box they sent to me to ship the device back to them. Yes, they didn't cross ship a laptop, but that's not practical.

    My experience with Apple's Genius Bar, however, hasn't been so rosy. Personally, I'd rather wait on hold in my house for 2 hours than wait around at a Genius Bar for 2 hours for someone to actually help you. Granted, it was crowded, but it's irrelevant to this discussion.

    When the problem and solution is crystal clear to even the most ignorant person then HP's service is fantastic: ie: Won't Power On, Disc wont eject, Nothing on screen.

    However with intermittent issues HP's support is horrible. Even speaking with a supervisor nets little reprieve from ignorance.

    The Envy line comes with its own dedicated support group that is not the usual, outsourced to India group. Quite a bit better. Also, strangely I have seen memory pass the Pc-doctor tests (usually what HP uses outside of the BIOS runs) but fail memtest. Not sure why, could just be different test algorithems Reply

    What kind of 13 inch laptops have discrete graphics anyway?
    Except maybe that smaller Alienware.

    <i>My preference would be two cables: one for power and one for peripherals/display. Today, it's five.</i>

    What you've just said is that Macbooks need a Dell Latitude-style docking station option in the worst possible way. Your preference is 2 cables. Mine is zero. Just snap in. (I've had this for over a decade now)

    If Apple is serious about phasing out desktops as you suspect, that'll be something that needs to come first.

    I've always been hesitant of docking stations. I've had a Dell that for the most part would undock somewhat correctly, and currently have an HP work computer that refuses to undock at all. For me, the convenience has always been hampered by the usability. Reply

    Actually, with MagSafe power and Thunderbolt, that's essentially possible. A dock that includes a connection to both ports could offer Mini-DisplayPort, DVI, VGA, USB, Ethernet, FireWire, eSATA, and Thunderbolt connections, and optionally, even a PCI slot or two. With 4x PCIe compatibility and 20Gb/s bidirectional throughput, a Thunderbolt port has plenty of bandwidth for that. Of course, Apple is currently the only company who could offer it with the MagSafe connection, but a third party could at least reduce it to 2 quick connections. Reply

    Huh. My windows laptop has only 1 connection that handles mouse, keyboard, monitor, power, ethernet and external storage. 'Course that's the beauty and convenience of a (working) docking station, something that I never really thought was worthwhile until I actually got one.

    I'm bummed that consumer products don't come with one.
