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

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.

Silicon on Insulator helps with current leakage, though. The problem for AMD, as I see it, is the delay of its 65nm process.forPPP - Wednesday, November 30, 2005 - link
Interpolating results shown in this article, I think we won't see Turion Dual Core with more than 2.0GHz or maybe even 1.8GHz for now, because it will consume much more power. That's why Turion will be behind it till AMD gets to 65 nm. But then Intel will have new architecture.Cygni - Wednesday, November 30, 2005 - link
Heres a quick summary of my thoughts:Best mobile proccessor option ever produced. Would be silly not to get one with your next laptop. But it doesnt have the muscle for the desktop. Nuff said.

gaming wise, its looks good. Altho it would be more fair to compare a 2ghz yonah to a 2ghz Athlon X2 /w 2MB L2, being within 5% of 3800+ is very good already, considering that its a notebook cpu. the desktop version may even surpass Athlon64. I sure hope AMD also has something up their sleeves. Exciting match!defter - Wednesday, November 30, 2005 - link
"Altho it would be more fair to compare a 2ghz yonah to a 2ghz Athlon X2 /w 2MB L2"Actually current comparison is fair, since Turion has only single channel memory controller. 2*512KB + dual-channel memory controller Athlon64 achieves about the same performance as 2*1MB + single-channel memory controller.

Dual-core Turions will (supposedly) be socket S1, which will have dual-DDR2 channels.michaelpatrick33 - Wednesday, November 30, 2005 - link
How is it good to be within 5% of a 3800? The 3800+ has only 1024L2 cache total. Additionally, this is their 65nm product compared to a 90nm product and it still doesn't match it in performance? I was expecting more from Yonah than this. AMD already has dualcore notebook Turions coming in Q1 '06 so Intel does indeed look further behind.Additionally, I am not too fond of Sysmark as a performance indicator either way, but still I don't think AMD needs to run around panicing at this point.

If the FX-60 is a 2.6GHz dual-core then AMD will have something that will more than match any Yonah thrown at it (a 2.7GHz or so Yonah could conceivably beat it, I suppose). Yonah really does make things a lot more exciting though, since at least Intel is within striking distance.anandtechrocks - Wednesday, November 30, 2005 - link
You are comparing the most powerful AMD FX processor with a mid-range mobile chip? What does this prove?tfranzese - Wednesday, November 30, 2005 - link
Considering the single core Dothan at 2.0 GHz runs about $300 I don't see how you could say that a dual-core Yonah of the same clock is 'mid-range' especially for a notebook. I highly doubt the chip previewed today will launch at or below that price point, and probably much higher.
