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.

    We'll probably see DDR4 in the ARM space before we have it on Intel.

    Maybe this should be AMD's focus of attack: if they can't compete on performance, at least try on chipset features.

    Perhaps Intel's biggest concern would be if somebody comes along with a super-efficient x86 emulator for ARM. Going forward, "legacy applications" is going to be an increasingly important selling point to prevent ARM inroads on the low end.

    Microsoft keeping their Windows ARM version locked-down is a key to that too, and likely a deference to their relationship with Intel. But Apple is less likely to similarly constrain themselves.

    The problem with DDR4 is likely going to be the price. We all know how the memory industry likes to jack up the prices whenever a new spec comes out. Remember how expensive DDr3 was when it started to replace DDR2?

    Some people joke that this transition is the only time they make any money in the RAM business, and considering the low prices of DDR3 you have to wonder.

    DDR4 might offer some performance and power advantage on release, but it will likely be more expensive and take time (12-18 months?) to offer a compelling performance / $ advantage over cheap DDR3 variants.

    If AMD is trying to position itself as 'value' brand, chaining themselves to DDR4 (before Intel's volume brings down the prices for everyone) could spell their doom.

    Intel is set to launch Ivy Bridge EX on a new socket late in 2013 on a new socket. The on-die controller will likely use memory buffering similar to what Nehalem-EX and Westmere-EX use. The buffer chips may initially use DDR3 but this would allow for a trivial migration to DDR4 since the on-die controller doesn't communicate directly with the memory chips.

    Come to think of it, Intel could migration Nehalem-EX/Westmere-EX to DDR4 with a chipset upgrade. Vendors like HP put the buffer chips and memory slots on a daughter card so only that part would need replacement.

    Four cores and 95 W tdp.
    What is this?

    Yes this caught my eye and I would like an answer, too.

    Maybe it is one SKU with GT3 for desktop? Or maybe it is a 6 core part?

    Or maybe.....it is the mother of all overclocking processors. Muhahahahah!

    I suspect that 95W is the rated socket limit. This is similar to how Intel advertises Ivy Bridge at 77 W on the desktop but tells motherboard manufacturers to build around the higher 95 W figure.

    What is odd is that Haswell will move some of the VRM circuitry on the package which should restrict just how far off that 95W figure motherboards can deviate.

    What a great article, Anand!

    Felt so good to read a 'proper' Anandtech article after so long, instead of the usual Apple worship and cheap fillers.

    Haswell is looking very good. Would make an ideal upgrade for Sandy Bridge users. AMD is done, but thankfully Intel sees some threat from ARM so that will keep them innovating.

    I hope Intel make a sensible choice with Haswell SKUs and get away from their artifical crippling and segmentation tendencies. That's about the only thing that can ruin Haswell.

    Once again they bump up the number of transistors being used on their worthless video-and this time they even lower CPU performance (L3 cache) to appease their worthless video.

    Interesting article, but I guess I misunderstood previous articles...I thought Conroe through Ivy Bridge had 4 integer execution units per core? (As does Piledriver?)

    Good article and information that you need win 8 to fully utilize Haswell was new information to me. It will be interesting to see how much better Haswell will be with win 8 compared to win 7. Seems to be same kind of dilemma as with AMD Bulldoser/piledriver where there seems to be some kind of better performance with new OS, but how much will reamain to be seen. Reply

    Apple owns various CPU tech and design companies such as P.A. Semi. They can build their own CPUs (not x86 of course)...

    Apple will do what they can to take out the middleman.
