Intel Yonah Performance Preview - Part I: The Exclusive First Look at Yonah

Video Encoding
DivX 5.21 with AutoGK
Armed with the DivX 5.21 and AutoGK, we took all of the processors to task at encoding a chapter out of Pirates of the Caribbean. We set AutoGK to give us 75% quality of the original DVD rip and did not encode audio.
Dothan's DivX performance was dismal at best, and although Yonah's two cores improves things, it's still not enough to be competitive with the Athlon 64 X2.

Our homebrew WME9 test is up next:
Much like the DivX test, we see that although Yonah has come a long way from Dothan, it is still not competitive with the likes of the Athlon 64 X2. It is a shame, as we were hoping for more out of Intel's FP/SSE enhancements.

i am waiting for overclocking tests and most of all the coming release of a MAC MINI with this baby inside. I'm going to run windows on it if possible ( so does it come with VT or not ? ). Hopefully january won't be a let down from apple...tfranzese - Wednesday, November 30, 2005 - link
Are you dense?Ask yourself: What's the mini's price point? Now, what do you think this chip's price point will be?
I think you're dreaming.

I wouldnt quite put it like that. I think single-core Yonahs will find themselves thrown into the cheaper Mac Minis, I dunno if apple will actually make a premium version with the dual-core CPUs.forPPP - Wednesday, November 30, 2005 - link
I don't understand all those comments that AMD is 2 year ahead because Athlon 64 X2 3800+ is on average 8% faster.Yohan is MOBILE cpu, while Athlon 64 X2 is desktop. Please compare Yohan with Turion and then complain.
Intel has lead with 65 nm technology which means AMD won't catch it up for very long in mobile market. Turion dual core at 90 nm will be far far behind Yohan.

Yonah is a 65nm dual-core, Turion is a 90nm single-core....

[quote]Yonah is a 65nm dual-core, Turion is a 90nm single-core....[/quote]And that's why for now there is nothing to compare. Yonah is its in own class. Even "Turion Dual Core" will be behind it, because of power consumption problem.

Really? I can't pick a notebook up today that has one, so comparing a processor that's been shipping for quite some time to this one means little.
Further, no one seems to point it out, but does Yonah not have 64-bit extensions? If not, now that near every desktop CPU sold today has them it'd be a real shame if 64-bit Windows development gained momentum.

Great point. You are right. It's the biggest disadvantage of the Yonah.

WHAT power consumption problem?
Shintai - Wednesday, November 30, 2005 - link
Maybe the power problem with adding over twice the transistors.Dothan->Yonah ~140mio to ~151mio ~8% more transistors
Turion->Turion X2 ~105mio to ~233mio(X2 current) ~121% more transistors.
And transistors = powerusage.
