I was under the impression that only the Athlon MP CPUs could be used in SMP
systems, and the fastest one is still 1.2GHz.

Your impression is wrong, all socketed athlons can SMP, and the new
palomino core durons can too (not sure about older durons).

It seems that any Athlon (even Durons) work fine in SMP configurations.
(Although I don't recommend this for stability).
Most people using dual Athlons are probably using the higher speed but
cheaper Athlon parts with no problem.
I have heard conflicting reports of what is actually different about the
MP vs non-MP parts, with points ranging from "the MP parts are just
certified" to that MP actually has some different internals. Whatever
the case, I suppose the difference isn't earth-shattering and mostly
marketing (ala Intel).

They work, but not "fine". There are performance issues with
Thunderbird-core Athlons in SMP configurations that may slow them down
somewhat.

Non-MP Athlons to now have all been Thunderbird (or earlier) cores. MP
Athlons are Palomino cores. The new Athlon XP is a Palomino core. The
Palomino has specific fixes for MP operation (no more slowdowns due to
SMP), and various performance improvements.
If you don't want to fork out the extra cash for the "official" MP
Athlons, at least buy the XP variant.

actually (having had my hands on 1.2GHz t-bird and MP boxes) the MP does
appear to be noticably faster per clock then the t-bird version. the new
XP is supposed to be the same core as the MP (just different marketing) as
I understand things.

The MP athlons are 50% more expensive than non-MP, but they dont have 50%
more performance.
Pretty simple purchase decision for me at least...

What kind of performance slow down? I have two Thunderbird 1.4Ghz
on an Tyan Tiger MP and they are quite fast (that is what I call
totally-subjective-and-no-value-at-all benchmark :-)

I've hear about some problems with the ALU Integer operation,
mainly reported by SiSoft Sandra SMP tests, (look at the Tyan forum
in http://www.amdmb.com), but at the end it seems that both the Thunderbird and
the Palomino have the same problem.
I would like to benchmark the ALU Integer operation in SMP under
linux, maybe after all the low scores are due to a low quality OS :-)
Do you know about any "standard" benchmark that run in linux and stress
SMP ALU Integer operation?

I bought the Thunderbird because they cost half the money than
the MP, and mainly because of availability (uhmm, not sure about this
word), here in Spain few people knows about MP Athlon, and even fewer
could get their hands on them.

It's palomino core. It means, new SSE instructions, bigger TLB cache,
prefetch, and 20% power reduction. All this for maybe 5%-15% performance
increase. And a not so nice increase in price tag :-o
Dual 1.2 non-MP is fine for me thanks... plenty fast and cheap.

you can always get a better price/performance ratio if you back off to a
the next-to-the-best generation of equipment. if you need the performance
though you can't do it with the older equipment.

Well yes, the 1.2 non-mp tbird is the sweet spot for price/performance at
the moment. Spend 50% - 100% more and you can get 20% better performance.
I didnt need balls-to-the-wall performance -- bleeding eyeballs was fast

Oh, you are right.
I meant MP vs XP part, sorry. From what I gather, MP is no different
from XP, although perhaps "certified for SMP" -- despite costing more
per MHz.

Completely Agreed. I am thinking of getting a dual AMD system for doing
more kernel work (tackle AMD and SMP). My main machine is a P3 now.

Here comes what I've found so far fro single Athlon XP on Linux.
http://www.linuxhardware.org/features/01/10/09/1514233.shtml
Summary and thanks for your fast replies:
All Athlons/Durons except the first SlotA ones (Athlon I; 0,25 ?m; no apic;
no available boards) support SMP. I know it before from the docs...;-)
But "only" the "latest" Athlon MP/XP (Palomino core) and Duron (Morgan core,
based on the Palomino core) support it "very" well. This is due to the
enhanced TLBs and cache redesign.
Only difference between Athlon MP vs XP is that the first is "validate" for
SMP.
So any dual numbers? I know that Paul G. Allen would upgrade his Tyan Thunder
K7 dual 1.4 GHz TB Athlon to an dual Athlon XP.
Greetings,
Dieter

Are you sure it is related to SMP and not the fact the Palomino core is
faster in general?
I'm not saying non-Palomino-core Athlons don't have SMP issues. I'm
sure something is different -- a lot of errata is fixed (and added) in
between core revisions. I'm just not so sure a measurable difference is
easily shown...especially when there are other reasons for a performance
increase in the core itself.
Anyhow, I don't want to OT...

Yes and No. ;-)
Robert have a look at the direct comparisons of dual 1.2 GHz Athlon TB and
1.2 GHz Athlon MP. There are many flowting around. The Palomino core
enhancements are even at the same chip clock very good for SMP.

> I'm not saying non-Palomino-core Athlons don't have SMP issues.
They don't have issues but they are (much) slower in dual configurations for
specific test cases.

The differences _are_ easily shown.
So the Athlon XP (Palomino core) _IS_ the way to go...8-)

Yes, it's an architectural problem with the Thunderbird core. It turns
out that in SMP configurations, the Thunderbird can actually hinder
performance in certain cases (i.e. benchmarks show very little
performance improvement for dual Thunderbirds over single Thunderbird,
while same software scales almost linearly with dual Palominos over
single Palomino).
I don't recall the exact cause, but I think it had something to do with
poor cache interaction -- cache-line ping-pong perhaps?

The issue right now may be RAM cost. I just bought 512MB PC133 for
$140/GB, while "registered PC2100" memory is about $900 from the same
source. I think that's what the Tiger wants, isn't it?

Registered ECC PC2100 DIMMs are $40 for 256MB at crucial.com. The local
computer shop has $129 for random taiwanese 512MB DIMM and $193 for
Corsair brand of same.
I dunno where your $900/GB figure comes from.

The Tyan Tiger and Thunder both take Registered DDR DIMMs. Though
anandtech got it running using only one pair of unregistered, other
combinations of unregistered failed to boot. There are also no SMP
athlon chipsets that use PC133.

registered ecc dimms from crucial and kingston valueram are barely more
than non-registered parts... I see the 512MB kingston registered ecc ddram
part for $220 from a large mailorder house. the same spec part from
corsair is still $489 from the same vendor. given the headaches that
result from having to debug problems/faulty dimms on a machine with 2GB of
ram and the non-trivial engineering that went into getting 4 reasonably
spaced ddr dimm sockets on the mainboard. I expect registered ecc dimms
will be well worth it, if only so that you can rule out the memory as the
culprit if you have certain kinds of issues...

512MB modules are built using either 128-Mbit DRAM
or 256-Mbit DRAM. The former has twice the number
of DRAM IC over the latter. Due to the higher density
DRAM, there is a significant increase in cost. Since
Corsair uses 256Mbit DRAM, their 512MB modules
cost a lot more.
When you see a much cheaper 512Mb modules, that is
because it is built using 128Mbit DRAM.

I have very good experience by testing with a memtest boot floppy (see

TC computers. They have the cheap memory, but the motherboard specs ask
for "registered." I'll take a look at crucial with that in mind.

512MB registered at $450ea. The 256MB are about the cost you mention, but
allow only a single GB with no room for expansion. I tried all weekend to
get into crutial.com and kept getting "too busy to accept you" messages,
so it may be great but not currently useful. Yes I tried from several
site, and at 2:10am Morning when I was fixing a server...

Registered ECC PC2100, got 2 sticks of this in my Tiger MP and works
perfectly. Dead cheap too

1stchoicememory.com offers PC2100 DIMMs that are guaranteed compatible with
whatever system you specify. Their 512MB DIMM is only $105. They'll pay for
return shipping if it doesn't work. I ordered one, so I'll find out next week
whether it will work.

wierd. Never got a server busy from crucial. Anyway, I see a couple of
hits for Corsair registered ECC at ~$200/stick on pricewatch.com, as
crucial doesn't list PC2100 ECC registered in 512MB sticks.

I see 512MB PC2100 Registered DIMMs for $105 on Pricewatch.
Am I missing something here?
They accused us of suppressing freedom of expression.
This was a lie and we could not let them publish it.

as also is yours; all athlons and durons, including the slot versions of
these processors, are SMP compatible. however, amd only officially
supports running smp combinations with the athlon mp chips.
IIRC, all AMD chips (P6x86 and up) are SMP compatible, however the older
chips (P6x86) are OpenAPIC standard versus the current APIC standard (i
forget the name).
hope this helps

BTW current rumor has it that Athlon XP's are supposed to be smp-disabled.
Apparently they have not changed the masks yet as a friend installed dual
Athlon 1800+ XP's in his S2460 this weekend...
So you have been warned...

Yes. The price of PC2100 is dropping like a rock everywhere, and the
source I quoted at $50 is now just over $100. We're shooting at an
off-topic moving target ;-)

Registered? ECC? Timing 2, 2.5, 3?
512 MB ECC reg. PC2100 CL2 org. INF ca. $100 exc. vat here
Hopefully tomorrow will arrive a thunder K7/SCSI, an evercase ECS5000 with
NMB PS, 2 * XP1700+ (I'm stingy), and 4 nice dimms here.
First time, that I'm getting a bit nervous about stuff since decades...

IIRC, the Infineon modules with 512 MB are two-bank modules. The board
only supports six banks, so I fear that you can only use three of your
four modules.
