once intel decides to put the M on the desktop AMD simply unleashes their next wave of A64 at higher clock speeds. if you notice AMD just releases a speed grade only to foil intel's top of the line. they need not release newer speed grades till the need exists. this way they can maximize profit from the current lineup.

Also when intel releases their desktop M, and AMD responds the M will be more crushed. notice how a 2.8ghz M barely beats a 2.4 Ghz A64? note further that DOOM3 is highly cache dependent, hence the 2MB cache helps it alot vs the 4000 with 1MB cache and a 400Mhz speed difference. throw in a 2.6ghz FX-55 or slightly OC that to 2.7 or 2.8 and watch the FX crush the M in every major benchie

The M is very strong in some areas but very weak in others, that's it's big problem (besides price which can be no problem if they sell in mass)..A64 is strong accross the board. It's power consumption is touted as an advantage but you have to wonder how well this will hold up when clocked the same and higher as thier A64 90nm counterparts. We shall see.. But as Dapunisher noted even the A64's are coming 30W and less.

I can't wait to see FULL Benchmarks, power, price of these babies.. dispite my ealier pessimism I am a fan of effecientcy which the M has in spades.:)

yeah an overclocked Dothan at 2.8 Ghz will beat a A64 @ 2.4 Ghz. Surprise ?

Get the FX and set it up @ 2.8 Ghz( just like MDme said), then we'll see. One more thing, Intel is only planning small speed bumps, we wont see 2.8 Ghz Dothan?s any time with the next year. Like Zebo said or hinted at, the Pentium M has poor floating point, where its strong in some area's its weak in others.

The Pentium M's saving grace is it's low power consumption and heat output.

Performance wise, this translates into a CPU that is better suited for dual-core architecture.

Whereas if you throw two A64 cores into the same die, you might have some thermal output issues, a dual core Pentium M will still run with a moderate heatsink.

By the way, I have a Dothan 1.7 and the ram is not DDR266. The FSB of the chip is only 100 MHz, which is quad pumped for 400 MHz. The ram runs at a divider, ,so it runs at DDR333. This sounds rather funky, but I guess it works.... although Sandra puts it at just about 2300 MB/s, it's still above 2100 which is the max for DDR 266.

It's pretty impressive that they got 2.8ghz on air, but you have to wonder what a 22% increase in Vcore is doing to the lifespan of the chip. Anybody know the max operating voltages and temperatures for a dothan?

a 22% increase is not that much, especially for a chip that is mobile.
i run my mobile barton (normal voltage 1.45) at vcore of 2.15 for benching, which is all they were doing there. that is more than a 45% increase in voltage. and they were using ln2!

a dothan is a mobile p4? correct? and they have lower spees becuase they do mroe work per cycle as opposed to the normal p4? but amd still does more per clock than dothan?

does the dothan support hyper threading? what kinda socket it?

Hmm looks like theres an updated article here with a lot of benchmarks.

It's not in english though. These chips are definitely very interesting. They hit 2.55ghz on their 1.7ghz chip that runs at newegg for 250 bucks. Looking at the benchmarks at 2.55ghz it basically performs like an a64 4000. Intel definitely came back on my radar with this.

i posted this awhile ago, i re-posted the thread at the very begining of this one. it has a lot of posts under it, it probably would have been a better idea to keep all the Dothan info under the same thread...

Umm the link in your thread isn't the same article. This article came out 11/2/2004.

Stability Tests: An idea that we had jointly with DFI and who will be soon available on some other charts: Inclusion directly in the BIOS that a copy of Memtest86+! This makes it possible to test the memory without any peripheral of connected on the chart. Moreover, it will be soon possible to make the same thing with the CPU thanks to CPUTest86+, which signs here the launching of the phase of Beta-test
They have memtest86+ in the bios already? Schweet! CPUTest86+ coming too? :cool: Too bad Azalea couldn't be included on this board, it would have made it a better HTPC choice.

No, the Dothan is a tottally new design from Intel's Israeli team; it is NOT of the P4 design but rather more from the P3 design.

Right now the Dothan is still hindered by a few things (which are dimished, but not eliminated with overclocking) that would give it even more performance.

For starters, it only operates at a (stock) FSB of 100MHz X 4 ... this goes back to the original Northwood days. Overclocking helps this immensely, but if they would be to make faster Dothans with the P4's 200 MHz FSB it could only help.

A more important factor is the P-M's weak FPU performance (compared to the Athlon64). Dothan really needs SSE1 and SSE2 (and, why not, SSE3 as well) to become a desktop FP monster.

It's potential is incredible though, notice that the 2 Ghz Dothan runs effortlessly on cr@ptacular laptop cooling, so obviously that chip has huge headroom just by using a more effective desktop air cooling solution.

I'd buy that in a heartbeat. PM and OC it till the fat lady sings. It still gets me why they don't just release the Pentium5 as a rebrand of the PM.

Those are some nice numbers!

Looks like the OCing crowd has a new mobile CPU to play with :D

just a further note, the Banias was largely just a P3 with a new higher frequency, lower powered bus and double the L1 and double the L2 cache. This is highly simplified of course. The processor went from 44M transistors to 77M. Obviously a complete overhaul. the Dothan was largely another revamp of the same calling. its amazing how well the P3 is still doing in todays market :)

Of course, the P4 design was just a marketing gimmick and nothing more.

P6 architecture is boss!

!

So true, I was dismayed by the loyal following intel enthusiasts had with the P4... While justified with the northwood everything else since '01 has been beat for less money coming out of AMD. The general public buys p4 that's fine they buy the name and high number hype..

But for everyone from your average joe (outlook, IE, word, spider solitaire and maybe winamp/wmp) up to the casual gamer they are never going to see or feel the difference between a p4 and even a a64 at equivalent ratings (and from what i've being reading fairly regularly on the forums, many folk who have tried both find the p4s with HT are often more 'responsive' feeling around the desktop-tho equally as many claim the opposite (from a rough impression :) )).

It certainly is true that AMD offer better price/performance, and ultimately absolute better performance in most applications these days, but i think the nature of this difference is exaggerated by folks like us on the forums, going back to my starting point, you sit maybe 6/7ths of the computer using world down in front of a modern AMD and Intel system, they really won't be able to find a difference for general use. Given this guess which one they'll go for :p The one with the 'intel inside' sticker of course- its a classical case of (from the relatively uninformed consumers point of view ne way), looking at two very similar products and going for the one that they know ('cos intel are the marketing masters compared with amd (a huge budget always helping there!)/trust/have used before :p

A rather irrelevant 2 cents but there u go folks :)

Its not that great. It does better in gaming than a P4 EE and even beat out the FX in Far Cry and did better in a couple of benchies. But for the most part not in the FX class and it performs worse in just about all non-gaming areas than current P4s. Only overclocked to 2.3 as well. Its alright I guess. But not $450 dollars though.

I agree :) What he says at the end is probably close to what will happen though
Intel?s Dothan core, unfortunately, suffers the most due to its aging 855 chipset backbone. In order for the Pentium-M processor to make any real inroads in the enthusiast crowd, many will want a new chipset with PCI Express, native SATA RAID, and perhaps a dual channel memory interface which supports more than 2GB of memory. Perhaps we?ll see such a chipset in the near future, but we?re not holding our breath for now.

We wish Intel would realize that they have a potentially incredible product with the Pentium-M and the Dothan processor core. Multiple Dothan cores on a single processor could alleviate any issues that the core has with workstation application performance, and would still produce half the power of today?s Pentium 4 processors. Throw in EM64T, SSE-3, Hyper-Threading, and perhaps even an on-die DDR memory controller, and Intel would have an amazing low power, high performance product.
It will be a real beast if they can do most of those things. I don't think from what I have read that HT is a good idea for that architecture though...
