I know the Atom is weak, but how does it (I'm referring to the single core version) stand against a Pentium 4-M? (I'm neither referring to the much faster Pentium M nor the much hotter Mobile Pentium 4)?

And has anyone made a comparison between a top-of-the-line Pentium III processor (1.4 GHz, 133 MHz FSB) and a single core Atom?

Maybe this info is "more than nothing":

Atom

Pentium(R) III
http://boincstats.com/stats/host_cpu_stats.php?pr=bo&teamid=&st=1600&or=0

Look at the column "Average credit per CPU second"

I did put my PIII S 1.4Ghz system against my P4 2.4Ghz system. However, I was just comparing processing vs power efficiency. Turns out the PIII was better per watt then the P4, but would produce lower average work.

After some searching online, I realised that an Atom N280 (1.66 GHz) is on par with or slightly faster than a Pentium 4 1.6A (1.6GHz, 400MHz FSB, Northwood 130 nm) based on the SuperPi benchmark.

I assume that the Pentium 4-M 1.6 (1.6 GHz, 400MHz FSB, Northwood 130nm) has the same performace as it's desktop counterpart.

http://www.pcstats.com/articleview.cfm?articleid=1130&page=4
(SuperPi 1M completion time - 1 min 45 sec)

SuperPi 1M can be completed in 1 min 31 sec on an Atom N280 netbook.

So most of the netbooks out there today (using the N270 and N280 CPUs) have CPU performace similar to the latest notebooks of 2002 (running on Pentium 4-M CPU at 1.6 or 1.7 GHz). However, the Atom has many advantages over the Pentium 4-M such as much lower power consumption (2.5W vs 30W), an improved instruction set (no SSE3 and no SSSE3 on Pentium 4-M) and Hyper-Threading capability.

I ran some benchmarks on my Intel Atom based ASUS 1005HA netbook and posted the results here: ASUS 1005HA - Intel ATOM 270 benchmark results


Here the results of three runs on the BOINC Manager Benchmark:
#1; 725 floating point MIPS (Whetstone) per cpu, 1877 integer MIPS (Dhrystone) per cpu
#2; 722 floating point MIPS (Whetstone) per cpu, 1844 integer MIPS (Dhrystone) per cpu
#3; 728 floating point MIPS (Whetstone) per cpu, 1883 integer MIPS (Dhrystone) per cpu

I've been crunching with a Samsung Netbook for just over 1 year. It has sucessfully crunched tasks on 9 projects. My previous main cruncher was an Athlon XP which has been powered down since May. I usually crunch about 23/7 including 3 or 4 hours a day while running on batteries. I have a car power supply and I am on the road about 10 hours a day, 6 days a week.

I also use T-Mobile mobile broadband (3GB/month) and public WiFi in coffee shops and McD etc. All my recent crunching has been done on this one PC.

Yes, but your Atom has a Nvidia (CUDA) card. Much of the work is being done by that?

Nothing wrong with that, and using a low power CPU to feed a GPU is a sensible option, but it doesn't really reflect the power of the CPU alone.

I have an old laptop with a P4m @ 1.8 GHZ. I am also very much interested in finding out the results, because it would give me a direct reference point on how this old laptop behaves vs the new netbooks. I will run the wPrime benchmark and I can post the results. I like this benchmark. It's located here:http://www.wprime.net/?q=download

If someone can run it on an atom PC and post the results here that would be great.

"Performance
The performance of a single core Atom is about half that of a Celeron of the same clock rate. For example, the Atom N270 found in many netbooks such as the Eee PC can deliver around 3300 MIPS and 2.1 GFLOPS in standard benchmarks, compared to 7400 MIPS and 3.9 GFLOPS for the similarly clocked (1.73 GHz) Pentium M 740."

So I guess a dual core Atom is = to a Celeron of the same clock speed, just a lot less power.

Just curious, why buy an Atom? Seems like a step backwards....I don't know the uses people have but am really curious and am not trying to be a Smart*ss.

Very low power requirments. In the case of a netbook. You can get incredibly long run times with smaller batteries then you could have in a notebook. Also for Nettops they are useful if you don't need a lot of computing power. Like a receptionists desk where the most demanding application may be solitaire.

So basically wordprocessing and internet?

my netbook runs VisualStudio 2008. Not very fast of course but sufficiently fast to be used.But very low-level intel videochip makes it absolutely non-gaming host ;) And BOINC/SETI runs just fine in background.
With full CPU load and constantly enabled screen it can work >5hours. It's just impossible fot usual notebook.
For example, Lenovo 3000 V200 ultra-mobile notebook that has slightly bigger display (12,1" vs 11,6" on my netbook), smaller hd-drive and roughly same memory installed (2GB vs 2GB) can work in highperformance mode approx one hour or even less. Netbook in its high-perfomance mode works >5hours.
If you in move it's just what you need.

ADDON: for comparison, here that Lenovo notebook:

(I upgraded memory today to 4GB in hope it will not use hdd much and will get cooler a little)

I'm using them for servers -- sixteen watts total (including a hard drive) and plenty of CPU power.

It's not just less electricity. Reduced load on the UPS means more run-time (measured in hours, it's a BIG UPS), and less heat is a good thing as well.

I'm likely going that route to replace a very old Via Eden C3 system. It's very nicely running Gentoo but it can sometimes be slightly too high on latency for some of the network traffic management. No surprise really! The final kill-off is that I want to add some USB2 devices to it whereas it's a very old USB1...

One or two Atom netbooks are certainly an idea but I need a PCI(e) slot to put in a NIC for a second ethernet port...

Any alternative ideas?

The new Via Nano looks really nice but it is also at a silly price for the task. Via C7 possible but also a little high on price. Any good Geode or ARM systems perhaps?...


Cheers,
Martin

So they have their uses but aren't something you should run out and buy your teenager? As I have always been a power user these chips and Celerons have always puzzeled me as to why they sold. I had 2 celerons as POS's but as time went on the machines were being used for more and more and I had to replace them with low end mainstream chips as time was a big factor. Someone at bestbuy was trying to sell a friend of mine an Atom and he called me and I told him to get an Intel Mobile chip instead as it was a present for his 14 year old daughter. She will play a game or 2 I would bet. Thanks for the responces I see they do have their niche.

I don't know what type of suppliers you have in Europe, but NewEgg has a bunch of Intel Atom Micro-ITX motherboard and CPU combos available for purchase. Atoms aren't exclusive to netbooks.
