Phoronix: Intel Atom Running At 2GHz With Hyper Threading

While it already seems like the Intel Atom processor family has been around for quite a while, it's really only been one year. Today Intel is celebrating the one year anniversary of the Atom processor from the Intel Developer Forum in Beijing. To commemorate the one year anniversary, Intel has introduced two new members of the Atom family...

Phoronix: Intel Atom Running At 2GHz With Hyper Threading
The Intel Z550 is the first Intel Atom processor to support Hyper Threading. It was just recently with the introduction of the Core i7 that Hyper Threading had been reintroduced to allow for eight logical CPU cores. Now with a Hyper Threaded Atom, the operating system will see two cores.

This is absolutely, totally false! Almost ALL Atom processors support HyperThreading, including the most common N270. The only ones that don't are the lower-power ones from the "Z" series.

Please document yourself before writing falsehoods! You've benchmarked several Atom netbooks, did you try "cat /proc/cpuinfo" on one for kicks?
Check this out:

People come here expecting accurate news, things like this make one question the accuracy of other articles :-/

Ouch :D

But anyways, just report the issue without complaining. Instead, complain if your report gets ignored.

Just a typo... It's been fixed. Running on little sleep this morning.

The Atoms all have in order pipelines... now if they had made an out of order Atom .. that would be interesting

Sorry, I'm quite lacking in the sleep department myself and it tends to make my reactions harsher than they should be :)
Glad to see this corrected!

Man, I can't believe it only uses 3 watts - that's amazing.

It will hardly beat a single core of a K8 at 800MHz in a lot of tasks.

The german computer magazine c't ran a comparison of most current cpus shortly ago. Among other things, they also compared energy efficency (in calculations/time, don't now exactly which benchmark they took anymore). The Atom (1.6 Ghz) ended up last, and I don't think this would be much different for this new Atom.

If you own a MSI wind with a recent BIOS you could try to oc the 1.6 cpu to 2.0 too ;)
