7/28    The Athlon architecture is often described as "having lots of
        headroom" as compared to Pentium.  But what does changing
        architectures buy you in the Mhz race?  Why will the P4 be able to
        make 100 mhz improvements where the P3 allows 33Mhz?
        \_ In general, newer architectures are pipelined more heavily,
           so for a given process, the clock to clock delay is shorter,
           so the chip can be run faster.  -nweaver
        \_ Bigger P ratings are cooler.

12/4    A question to you old crufy alumni: So lately we've suggested
        VMs, and been asked why it's necessary. We've suggested top-of-the-line
        hardware and been told we don't need that much power. So I'd like to
        ask -- what exactly do you think the CSUA is supposed to _be_?

11/7    Yay, Dell unveils OptiPlex 740 with Athlon 64 X2, although it's
        rated at the same speed as Pentium D dual core (but still naturally
        lower than Core 2 Duo)

9/7     FYI, the Athlon 64 X2 4600+ 65W (energy-efficient) retail CPU is now
        available on for $250 (zipzoomfly has been advertising $295+
        for several weeks, newegg doesn't have it)
        \_ Nooo!  It's all about the E6600!  /me rubs his E6600 all over his
           pale, naked body.
           \_ Well the E6600 is somewhat faster than the 4600+.  A fairer

8/7     Microcenter in Santa Clara has E6600 processors, OEM for $379.  I just
        got one.  If they still have some, you can request a "one day hold".
        \_ I'm still wondering what use everyone has for a CPU like this that
           a CPU at half the cost won't do.  I understand this is the bang for
           the buck price point.  What's all that bang for anyway?

7/25    I want to buy a quiet PC. It doesn't have to be completely silent,
        just quieter than the one I have now (something I could put in a
        bedroom and still fall asleep). Can someone recommend a prebuilt
        but configurable computer (Dell etc) that isn't loud? I've seen some
        websites like but those seem very focused on
        building your own system, which I don't have time to deal with right

7/26    Re the AMD price cuts Monday, shows the Athlon X2 4600+
        Socket AM2 Windsor as $330 and out of stock, but has it
        in stock for $240.  Also, the energy-efficient variants are only
        supposed to have a 10% mark-up, but no word on availability.
        Don't get screwed.
        \_ How much MORE efficient?

        "Here you can see the quintessence of Conroe's triumphal hymn. While
        the efficiency of Athlon 64 FX is higher by 58% versus Pentium eXtreme
        Edition 965, Conroe's efficiency is higher by 23% versus Athlon 64 FX!
        It seemed impossible to create something more efficient than the AMD K8
        core, but Intel engineers managed to do it." (June 15, 2006)

3/2     How is an Opteron different from an Athlon64?
        \_ Most Opterons require registered DIMM (940pin) and most
           have 3 HT links.  1xx series only have 1 usable one, though.
           There're some 939pin Opterons, which are basically identical
           to Athlon 64.  All Athlon 64s have 1 HT link only and use
           unbuffered DIMMs.  Internally, they're identical other than

11/7    Re: "Teaser: write an algorithm for finding prime numbers." on 11/1,
        I wrote some C code to find all prime numbers between 1 and 4294967295
        with 32-bit math (no 64-bit or floating-point math).  It took about 84
        hours on a 502MHz Sun-Blade-100.
        \_ Quickly thought through, totally untested alg.
           Make a list of (n, n^2) tuples for all n < 2^16 and n is prime.

8/9     Can anyone recommend a vendor that sells Athlon 64 X2 (dual-core)
        configurations for small businesses?  Basically it looks like we're
        buying Pentium D machines from Dell otherwise.
        \_ You want a desktop (non-buffered memory, ECC not required, etc.)
           or a workstation?  I see HP has workstations using dual-core
           Opterons.  Look for xw9300.  A bit pricy, but you get what you
