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 :)

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

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.
