Why 2200+ & 2800+ in both model 8 & model 10 Sempron?

    There is 1500 (2200+) and a 2000 (2800+) in the Sempron model 8 range.
    There is 1500 (2200+) and a 2000 (2800+) in the Sempron model 10 range.

    In these two AMD publications on page 21 (as numbered by AMD) of each
    document they show a pair of 1500 (2200+) and a 2000 (2800+) models.

    Why is this?

    AFAIK both the model 8 and the model 10 Semprons are Socket A, 333 FSB with
    256K L2 cache.

    looks like overlap model nos, but possilby no overlap in *availabile*
    models?

    anywya, i found

    http://www.driverheaven.net/reviews/Sempron/
    The Sempron comes in 3 varieties, on the desktop there are Socket A and
    Socket 754 models. On the Mobile side there are Sempron’s based on
    Socket 754. Our Sempron review sample is a Socket A 2800+ clocked at
    2Ghz where as a Thoroughbred Athlon XP was 2800+ clocked at 2.2ghz. The
    Sempron FSB is running at 166MHz (333 MHz effective) as the Thoroughbred
    also did and really, that’s all you need to know about the CPU"

    ie, they didn't test the newer semp/sock 754

    i'm guessing the older (sock a) semp runs hotter than the socket 754
    semp??

    and then there the mobile cpus....

    here's someone's chart. not sure how up to date
    http://www.thedigerati.us/info/amdcpuchart.html

    notice teh semp 3100 (in hte blue table cells) has different socket and
    MHz

    if you figure it out, post pls :)

  3. Correct. The Athlon model 8 (TBred) is manufacturered with only 256KB of L2
    cache (how much a Sempron has). The Model 10 Athlon (Barton) is manufactured
    with 512KB of L2 cache. These require more silicon so are more expensive to
    manufacture. The Bartons that pass all the QC checks become the high-end
    Athlon XPs, and the ones that pass all of them but have half the L2 cache
    faulty get half their L2 disabled and used as 256KB Athlon XPs (sorry,
    Semprons).

    Basically:
    [] Model 8 Sempron = TBred
    [] Model 10 Sempron = Barton with half the L2 cache disabled (no, it's not
    possible to re-enable it any more)

    If you want to actually get a Sempron (not recommended) you want the Model
    10's, because they overclock a bit better.

    The Socket 754 Sempron is an Athlon64 (Newcastle?) with half the cache and
    64-bit extensions disabled. It's a completely different beast to the
    Socket-A Semprons, which are just Athlon XPs with a different name and a
    higher model number (and hence a higher price).

    reading a bit more web stuff, i see:
    sock a is k7
    sock 754 is k8


    http://anandtech.com/cpuchipsets/showdoc.aspx?i=2139&p=14
    jul 04 [july info is a bit old, i guess]

    [seems Sempron 3100+ is still the only semp k8]

    Socket A Sempron will eventually be targeted at the extreme budget line of
    computing with the Sempron 2200+ clocked at 1.5GHz and priced about where
    we can find 1.2GHz Duron processors... looking forward to testing some
    extreme budget systems based on these processors.


    [looks like retail k7 semps are mostly 2800+ already. 2200 is gone? 2400
    going.]

    I just bought this Sempron 2200+:

    http://www.newegg.com/app/viewProductdesc.asp?description=19-104-201&depa=1

    and was surprized that it seems to be an overclocked Athlon / 333 MHz
    bus. Is it possible that they just started calling some Athlons by the
    new name? The ID says it is a model 8 - the price was right, but it
    runs hotter than expected for a 'new' model chip.

    * Model 8 Sempron = TBred
    * Model 10 Sempron = Barton with half the L2 cache disabled

    IF you subtract 400 from every Semprons number, you will get the
    approximate Athlon rating. So your Sempron 2200+ would be the same as
    an Athlon 1800+, etc. The same is true for socket 754 Semprons

    All Semprons are rated with a set of benchmarks to compare
    them to Celerons clock speeds and the resulting PR number reflects
    that . . . . they are not compared P4's or even XP's

    Do a bit of reading of previous posts there are lots of bit's of info
    in the group.
