Intel doubles GPU performance with Haswell – halves TDP

Posted at 11 September 2012 20:10 CEST by Jan Willem Aldershoff

During the opening keynote of the Intel Developers Forum (IDF) currently held in San Francisco, Intel’s executive vice president and general manager of the Intel Architecture Group, David Perlmutter, has demonstrated its new Haswell CPU architecture.

During the IDF last year, Intel already gave a sneak preview of the Haswell chips, but as its market introduction is near, Intel now decided it was time to reveal more details on the Haswell CPUs.

The technology giant showed a test computer with a mobile Haswell CPU and benchmarked it against an Ultrabook with an Ivy Bridge CPU. To demonstrate that Intel is more on par with its graphic processing, they decided to use the graphical Unigine benchmark.

The DirectX 11 benchmark was demonstrated using two different setups.  During the first  both the Ivy Bridge and the Haswell chips were fully utilized with impressive results. The Haswell GPU performed two times better than the Ivy Bridge GPU, the latter wasn’t even able to decently run the benchmark, while the Haswell had no problem whatsoever.

In the second setup both chips had similar performance, but the Haswell chip used half of the watts of the Ivy Bridge chip. The TDP of the Haswell chip was around 8 watts against 17 watts for the Ivy Bridge chip. Haswell chips will become available in 2013 and like the Ivy Bridge chips will be manufactured at 22nm.

Intel doesn’t want to use the name Haswell anymore, but instead refers to ‘4th generation Intel Core’ CPUs.

    Hmmm, I wonder what Ultrabook makers will do, put smaller batteries in their Ultrabooks or give us double the battery life...

      Most likely both.
      They'll reduce the size of the battery such that it's cheaper for them, but gets slightly longer operation.

        Laptops aren't exactly selling like hotcakes.. Also, prices for these premium technologies are going to outweight a laptop's usefulness even with a 50% processor power reduction.. the $300 - $400 per laptop (by the time etail/retail markup gets in the way) in increased costs outweight the power savings.

          Still pretty crappy probably when we compare it to Trinity, but a pretty big jump up for Intel integrated graphics.

          So now both sides will have IGPs approaching a GT640/GTX650 in terms of gaming power?

            Mine's due for renewal in about 6 months
            Got some bits hanging off ... the quad core CPU gets too hot to sit on your lap, and the video card turned out to be absolutely useless for anything, except quake 3 at 540p .

            Might opt for one of those gorgeous Asus Ultrabooks ....

            The lack of an optical drive annoys me, but not enough to dissuade me from buying a proper work laptop that weighs less than 1.4KG's

            I'd be glad to shave 100g's off the weight, and still end up with an extra 2hrs of battery life
