Looks like they made some nice improvements. Unfortunately, it's hard to make valid comparisons for or against it at this point as there too many unknowns still. If they bring it to the desktop and work a bit more performance per clock out of it and above all, keep the price reasonable, they might have a very competitive chip.

Nice, nice.. If I was rich, I'd sure get that in February :).. Expecting that AMD doesn't come up with anything new until June, Intel's got 3~5 months of joy coming! :music:

hmm...

what is a 2.0 ghz / 1meg L2 per core ... chip?

i know there is the opteron 170.

is it the opteron 170 they were using?

It ties on everything but gaming, then looses. How do you score one for Yonah ? Since your a troll and a fanboy ? Yes, its better than Pressler or prescott, but it still misses the mark. And we don't know about OC'ing or price either.

It's probably either a 4800+ or a 4400+ underclocked to 2.0 GHz... just my thoughts.

ah, yes that makes sense! :)

I'll admit it does do great in the power consumption and heat department. You have to think of that as well.

It's all about low power Mark.. I think in that first review system power was 100W loaded vs, 135W for same speed X2.. granted not huge difference like those 300W Plutonium D setups but still signifigant. Another feature we should get is much better mobo's with HD Azila audio from intel and better IDE/active armour driver than NF4.

Main questions are a) overclocks b) price c) and when, to determine if it's really any good or not.. certainly not the performance I expected clock for clock I expected a little bit better than X2's.

What I found most interesting about the review was the talk about conroe - the processor intel is really releasing to compete with AMD on desktop - Evidenty Conroe will have 4 more pipes hurting performance more - but allowing for higher clock speeds too. Next year should be fun.:)

AMD's new core, the K10, won't be released until some time in 2007. It seems that AMD is going to fight Yonah and briefly Conroe with high clock speeds. If Conroe performs as expected, AMD will indeed need a significant clock speed advantage to compete with it, as Conroe's avergae IPC should easily exceed the K8's.
Late 2006/2007 will be very interesting.

Those tests show that Yonah has enhance it's float point performance much, and the integer efficiency is better than Athlon64X2 about 15% or more.

I don?t care much about Yonah other than it being a preview for future Intel products, since it is a purpose built notebook processor, which has been on the most part engineered to supply next gen performance with a lower power requirement. I never expected to see ground breaking performance from this processor as it is constrained for use in a laptop.

However I am interested in Intel?s new soon to be desktop processors, Merom and Conroe. I think this article is good, because as has already been stated in the article it gives you an insight to what direction Conroe will be headed with regards to possible performance. I am still a little disappointed that clock for clock it doesn?t perform much better if at all then the X2, and the fact Conroe is slated to have more pipes (4 more I believe) seems to add further to the disappointment. Yes it will improve the headroom for higher clocks, but I would have thought this time, Intel would have had emphasis on engineering a chip similar to the performance of the Dothan, with respect to lower latency L2 cache, and fewer amount of pipes (which was still able to clock high albeit a single core). Although the number of pipe line stages is debateable, if Intel can squeeze a lot more top end frequency from the design, and if it indeed proves more beneficial for overall performance, then this would be a plus.

I also assume that with 4MB?s total L2 cache on the Conroe (against 2MB total on Yonah), would have yet a further L2 cache latency penalty, would it not?

That, OR my guess that they didn't say what it was because they are under NDA for the FX-60 that they used!!:D

IBM's POWER5 have 16-stage pipeline, but it is much more powerful than K8. No one should think that more pipes will bring the loss.
Conroe has 4-issue, it's IPC may be better than any x86 cpu.

Athlon64X2 has double L2 than Athlon64, but the latency is closely to the Athlon64. Yonah and Dothan has the same size of L2.

For Dual Core, more L2 does not mean the more latency.
Yonah(OC) can reach the more high frequency with the 14-cycle latency.

They won't keep the price reasonable; are Dothan's priced reasonably? This is a brand new architecture designed for a market where people will pay for it (notebooks).

Now you've done it.

Mostly right here. More cache != more latency. It is all in how they design/implement the cache. Dothan had 2MB L2, as did the later P4's; but the P4's L2 was much much higher latency.

Yonah(1.66GHZ) is about 240$.

Athlon64X2(2GHz) is about 315$. If AMD will sell Athlon64X2(1.8G), the price may be 270$.
If AMD will sell TurionX2(1.6G), the price may be higher than Yonah.

So the price of Yonah(1.66G) is reasonable.

In the float point test, POWER5@1.9GHz can very easily defeat the Athlon64 FX@2.8GHz.
POWER5 has 16-stage pipeline, but K8 is 12-stage pipeline.

so what is the disadvantages of the POWER5, heat?

Not to mention they are not x86
