Atom Dual-Core Performance Numbers Emerge
A spy-shot of the dual-core Intel Atom processor has surfaced. The picture reveals an important bit about the design of the processor. Dual-core Atom isn't about two processor cores integrated onto one die, but two dies sharing a package and front-side bus, much in the same way its distant ancestor, the Pentium D was built. This design allows modularity and helps Intel cut manufacturing costs. They don't have to build separate wafers of dual-core dice but rather use two single core dice and integrate them onto one package. The Atom 330 will be the first product based on this design. Early performance tests with arithmetic and memory bandwidth reveal a good level of scaling, close to 100% that of the N270, a single-core 1.6 GHz part:
Processor Arithmetic Test
Intel Atom N270 1.6GHz - 8291 kpixels/s
Intel Atom 330 1.6GHz Dual Core - 16920 kpixels/s
Intel Core 2 Duo U7700 1.3GHz - 24742 kpixels/s
Memory Bandwidth Test
Intel Atom N270 1.6GHz - 3.54 GB/s
Intel Atom 330 1.6GHz Dual Core - 7.18 GB/s
Intel Core 2 Duo U7700 1.3GHz - 9.53 GB/s
The tests show Core 2 Duo U7700 to outperform these, though it is to be noted that Atom 330 isn't based on the Core architecture and that the Atom is expected to be priced much lower, to cater to the ULPC industry. EeeUser forum has a set of numbers from tests that can be read here.

I own a Eee PC with an Atom in it, I love the little thing.
A CPU that scales its 100% as it should do :eek::eek::eek:
However I'd like to know how much more power is used by that dual core. It may not be worth it if it is doubled as well : (
the HT of today is tottaly more advanced then p4 got
Again, in a single core processor, it is nice to have. But once you have a dual core, or more, the usefullness really goes away. As the chances of it actually being used is reduced to almost nothing. Any work that would be helped out by HT, the second core would take care of instead.
here is a typical one of your posts
"HT is god i have a P4 oh and AMD sucks"
get over it your views are not backed by ANYTHING
yes i have a p4 that wil change soon and you probaly dont have the funds to buy what i am getting
and yes amd sucks at high end, extreme cpu's
and as i said before HT is the future on intels road map dont like it? go amd!
..zucht...
The extra threads provided by HT are useless in the current situation of computing except in computers with a single core. More threades, that go unused, are useless.
