    'Lackluster Haswell Muddies Intel's Future'

    From a seeking alpha article. Comments?

    "So, at this point, Haswell will launch in June as a CPU without a clearly defined market niche. The desktop parts are not compelling upgrades over Ivy Bridge. The mobile versions will be competing not only with Richland - which is a sincere tragedy -- and AMD's real stalking horse Kabini/Temash, but also with the 13W Ivy Bridge-Y CPUs that will be around until the end of the year. Overall, Intel's roadmap looks like a complete mess and as an investor I would be very worried about these benchmark numbers."

    • That is actually not true. Sounds like an AMD fanboy gone mad. I heard the same argument when Ivy Bridge was released. Essentially Haswell and the new chipset will have all USB 3.0 built in. Sata 6.0gb/s only. The graphics on Haswell are twice as good as Ivy Bridge and Ivy Bridge was about as good as a low level add on card. Intel is getting very serious about graphics and they well show up big in Haswell. So on paper this is what you have:

      1. 10-15 percent CPU processing power
      2. Extremely efficient -Low power mobile chips down to 8 watts
      3 100 percent improvement in graphics.
      4 Up to 16 USB 3 ports integrated
      5 4 Sata 6.0 gb/s ports vs 2 in Ivy Bridge

    • If all the points that Tom Luongo makes are true, then his arguments will have weight. It is unlikely that all the information he is using is correct. Even Tom's Hardware suggests that "the Haswell-based machine just looks like it needs a little tuning" page 2.

      You might start at the SiSoftware Sandra website that contains some more information on both the benchmark and some of the new Haswell features. SiSoftware seems to be working on soom analysis of new Haswell features (FMA, AVX2 integer extenstions, TSX, ...) and will be providing some measurements.

      SiSoftware on TSX which points out that TSX will offer "significant improvement" in MP concurrency which is multiple cores working on the same data. It is pretty good reading.

      Final Thoughts / Conclusions
      We have seen in the preliminary testing that TSX does deliver what it was designed to do:
      • It is relatively straight-forward to replace classic software locks with TSX versions. Applications can implement it now using exiting compilers by using a little assembler.
      • TSX locks using HLE will run with no appreciable performance delta on legacy CPUs - not better but no worse.
      • TSX appears to provide significant improvement in concurrency - and thus performance - on TSX-capable CPUs which is very important as the number of threads and cores continues to increase in modern CPUs.
      • Once operating systems will be updated to use it, the performance of the OS as well as locking API should improve. New locking APIs will be provided to allow applications easy ways to use TSX.

    • That's Tom Luongo, the well known idiot, from seeking alpha. AMD uber alles? LOL.
