While browsing the "Hot Deals" forum at Anandtech, I ran across the

"Intel Pentium D Dual Core 820 - 2.8GHz processor" for $271, possibly
minus a 10% discount from some coupon that I don't have. The actual
page showing the cpu for sale is here:

http://www.buy.com/retail/product.asp?sku=10409823&loc=101&sp=1

"64BIT MPU BX80551PG2800FN 2.80G 2MB SL8"

Nothing on the web page above indicates that this is a dual core cpu,
so my question is, "Is this really a dual core cpu?" It seems a
little cheap to me, but what do I know?

Having bought a couple of ink cartidges, I get buy.com coupons
periodically. I can send you one, or watch the fatwallet type sites.

Try searching the intel site using the part number.

It is indeed a dual-core processor, here's Intel's product description
for it:

http://processorfinder.intel.com/sc...Fam=1039&PkgType=ALL&SysBusSpd=ALL&CorSpd=ALL


Note that the Box Order Code matches up. For me personally though, it
isn't particularly comforting to think that a company would sell a
chip without labeling it properly and providing a quick description
such of the chip.

As for the price, it seems about average for on-line vendors.
www.newegg.com currently has a one-day sale on these chips, current
cost is $256:

http://www.newegg.com/Product/Product.asp?Item=N82E16819116213

I don't know what their regular price is, though I would guess that it
would be close to the $271 listed above.

If I were you I'd absolutely avoid buying current Pentium 4 Dual Core products. Things are going to
change once Intel releases multi-core Pentium M based desktop CPUs later next year.
Right now the best option is to build a cheap Dual Xeon system with a E7525 based motherboard and
two Nocona core Socket604 Xeon CPUs, you'd end up paying almost the same as for a Pentium D based
system on a good motherboard.

The Pentium M does VERY well in a few things, and not NEARLY so well for most things.

It runs slower and cooler, and is great if cooler is your primary design factor.

All rumors so far clearly stated that after the demise of Prescott/Tejas projects (with their insane
power requirements...) full control has been given to the Centrino division to deliver multi-core
high-performance desktop and server CPUs to replace the Tejas project and the Pentium 4 architecture
with a better one. The one that Steve Jobs decided to follow by switching from IBM PowerPC to
upcoming Intel new architecture based on Centrino/Pentium M revised technology in multi-core format
to appear in a year from now if not even before.

Dual Opteron would cost even less, perform in most tasks better, and
is upgradeable to dual core, making it effectively a quad system - you
can even put in the dual cores today, if the price wouldn't scare you.

No, you've got it backwards. The Pentium 4 (/related NetBurst Celerons and
Xeons) does VERY WELL in a very few things (basically code where streaming
throughput is what matters) and not nearly so well for most things.

The Pentium M is a much better general purpose chip; handles mixed and
branchy code much better.

Slower megahertz doesn't always mean slower processing. If you're doing
streaming video, the P-M is the wrong choice full stop. For most other
things, the P-M clearly beats the P4 at a given clock speed, and often by
a large enough margin that it's still economical.

And the year after that things are going to change again, and again
the following year, etc. etc. Buy what you need when you can afford
it, because if you're sitting around waiting for the "Next Big Thing"
you're always going to be disappointed.

Hmm..

Boxed 2.8GHz Pentium D processor = $252
Asus P5LD2 motherboard = $127

Total = $379
(prices both from www.newegg.com)

vs.

Boxed 2.8GHz Xeon (Nocona) $229 x 2 = $458
Supermicro X6DAL-XG motherboard = $318

Total = $776
(prices from www.pricewatch.com bottom-feeders)


That's a rather substantial difference in price between the two
setups! Ok, you might get a few more features in the Supermicro board
(the cheapest e7525 board I could find), but the majority of those
features would be totally useless for most users.

Both have their ups and their downs, neither is the out-and-out winner
from a performance standpoint. However the Pentium-M is definitely NOT
the end-all, be-all chip that a lot of people make it out to be. If
you're work is fairly floating-point intensive, the Pentium-M is a
pretty weak choice.

The following article contains a pretty wide variety of benchmarks
comparing the Pentium-M vs. the Pentium 4 and Athlon64 (all
single-core chips). All of these chips are run on desktop
motherboards (using an adapter for the P-M). There are a lot of
applications where the P-M comes in at or near the top of the list,
but there are also an awful lot where it comes it at or near the
bottom of the list as well, and it's not just streaming media stuff.

The fact is that the Pentium M was originally designed for mobile/notebook applications and not as a
desktop/server CPU. The fact that a design like that can perform better than architectures designed
for desktop/server high-bandwidth and massive floating point applications in many areas surely hints
something about what's going to happen when the re-designed Pentium M based multi-core CPUs will be
released next year to replace current Pentium 4 Prescott based CPUs....

That is a hope not a fact.

Whatever

Forgive Geno. He's an Intel fanboy, and rather clueless, as well.

Trying to insult me doesn't make you right. Your attitude given by your answer looks pretty childish
to me since you get so much irritated up to the point to try to insult me like that just because you
don't like what I said, a pretty basic analysis based on facts about Pentium M/Centrino
architectures and rumors up to now regarding its future.

Or maybe it simply tells us that 2MB of fairly low-latency L2 cache
can make up for an awful lot of other potential performance penalties
in a modern processor.
