    Keep up to date with the latest announcements & discussions on the hot topics.


    Also I find it strange that for the PHP compile, 7-Zip and GnuPG tests the Thinkpad W510 (with HDD 320GB Hitachi HTS72503) is the same with ZaReason Verix (with HDD 80GB Intel SSDSA2MH08 SSD). I would had expected ZaReason Verix to show better results in those tests.
    i also doubt the test, need more details.

    Well, I already have a business class HP machine (tc4400, not my choice), and the build quality is terrible on it, too.

    I'm inclined to trust Lenovo on build quality more. Apple is mostly pretty good on that, too, since it seems like all of their high-end machines are built to a higher standard. Of course, Apple has made some bad design choices, so you have to be careful, but I think the current MBP is a fairly well proven design.

    My requirements are a bit tricky to balance, since I need something relatively portable as well as powerful. That's where the MBP seems to fit well, but I'm not sure how portable this Lenovo is (I haven't gotten to handle one yet).

    Well, it has home and end buttons.

    After seing some poorly built Dells, Toshibaa, and HPs, I feel like the only really reliable laptop manufacturers are Lenovo and Apple.
    If you need a well-built machine, check the business lines of those companies. I have used some very high-quality Dell and HP machines in the past.

    All consumer-class notebooks more or less suck as far as build quality is concerned.

    Obviously, this has a business-class GPU, but I'm not really sure what kind of benefits that actually gets me (the difference between consumer-grad and busisness-grade GPUs seems rather intangible to me).
    You can run OpenGL quad-buffer stereo and get better performance in some commercial apps (check whether your CAD software can benefit from this).

    Oh, also, I went to the IBM website and was sort of ticked that you can't get this machine without Windows, apparently. Nice Linux offerings, Lenovo.

    I see. Thank you for pointing that out.
    Still, it remains the PHP compile test which I think must read many files from HDD to do the compilation which means many random reads. And on random reads SSD should be king.

    One question... The CPU is a Core-i7 quad with 2-way SMT/HT. In /proc/cpuinfo it bills itself as 8 CPUs. I'm presuming my kernel is built with SMT-HT-aware scheduling so it knows it doesn't really have 8 CPUs. But I've seen some articles that suggest it performs better if you just shut SMT/HT off in BIOS and go with 4 true CPUs.

    Anyone have any take on this issue?
    I've seen this issue with some specific applications and some HT cpus. If I remember correctly a core i3 cpu is faster at compressing files (real compressing, not synthetic benchmarks like the 7zip one) with HT off, but it's also faster at raytracing with HT on. I have the impression that this problem does not affect Atom cpus which greatly benefit from HT.
