Haswell Media Engine: QuickSync the Third

Although we still have one more generation to go before QuickSync can apparently deliver close to x86 image quality, Haswell doesn't shy away from improving its media engine.

First and foremost is hardware support for the SVC (Scalable Video Coding) codec. The idea behind SVC is to take one high resolution bitstream from which lower quality versions can be derived. There are huge implications for SVC in applications that have varied bandwidth levels and/or decode capabilities.

Haswell also adds a hardware motion JPEG decoder, and MPEG2 hardware encoder.

Ivy Bridge will be getting 4K video playback support later this year, Haswell should obviously ship with it.

Finally there's a greater focus on image quality this generation, although as I mentioned before I'm not sure we'll see official support in a lot of the open source video codecs until Broadwell comes by. With added EUs we'll obviously see QuickSync performance improve, but I don't have data as to how much faster it'll be compared to Ivy Bridge.

    Apple. Or are you joking. I personally hate Apple and have since the original iMac but their engineering is top notch when it comes to getting ideal performance from silicon to user. So.. guessing that's the reference. Reply

    A fine read, technically very comprehensive, but still overly melodramatic.

    While it is true that it is crucial for Intel to step a foot in the byod market some things still hold true:
    - In value and profit the PC processor market is much bigger than the byod processor market and will stay so for years because PCs, especially business PCs won't disappear anytime soon.
    - Nobody can touch Intel in this market, it has been proved for decades. Not AMD at the height of its success, not mighty IBM, not Sun, nobody.
    - Contrary to what you say Intel has a definitive production advantage and there are very few fabs able to compete. Note that Apple is incapable of producing processors, it is dependent on external manufacturers.
    - What Apple does with its processor is interesting business wise for its iPods/Pads/Phones, but Apple doesn't have the research power Intel and others have in the chip space and I can't see how it will innovate better than Intel and other competitors.
    - Intel is aware of its shortcomings, is pushing tremendously in the right direction. A competitor that doesn't rest on its laurels is a mighty threat, ARM beware.
    - If Apple stops using Intel processors, it will of course wipe a few hundred millions of Intel's turnover but won't be anything remotely dangerous for Intel
    - It remains to be seen that Apple users will accept yet another platform change.
    - It remains to be seen that it would make sense business-wise for Apple
    - I am quite sure many phone companies will be open about renewed chip competition and not letting a single platform become too powerful.

    All in all it seems to me Intel is as dangerous as ever, executing very well in its core business and heading towards great things in the phone/pad space.

    Why couldn't they at least stick to LGA2011? Reply

    One of the best articles on Anandtech in some time. This is great original tech industry reporting. Reply

    Congratulations, an intel cpu engineer wrote around 27 Dec 2012:

    "... Anandtech's latest Haswell preview is also excellent; missing some key puzzle pieces to complete the picture and answer some open questions or correct some details but otherwise great. ..."

    A few questions.

    Is there going to be a replacement (37W) for the current IVB 35W quad-core part? Quite a few designs are now dependable on this, lower power quad-core option - Sony S-series and Razer Blade, to name a few.

    When can we expect all mobile CPUs (except maybe for the extreme series) to fall into the 10W-20W range? In three years' time and 10nm?

    The decision to not include GT3 with desktop parts is very disappointing. A 35/45W low-voltage part with GT3 would make for an excellent HTPC build, among other things. Is there a chance Intel change their mind and start shipping GT3 desktop parts at some point?
