The dentist wasn't nearly as bad as I expected - the one redeeming quality about living up here is that the dentist office near our house is far better than any other I've ever been to, and I'm picky about my dentists.
A lot of you want to know how Yonah overclocks and I'd love to tell you, but our little Yonah motherboard doesn't exactly support overclocking of any sort, so that's not going to happen in Part 2.
What I am trying to do for Part 2 however is do a more in-depth apples-to-apples comparison between Dothan, Yonah and the A64 X2. I've got a 2.0GHz Dothan on the way, and I'm waiting to hear back on sourcing a 915G based Dothan board so we can have both Dothan and Yonah using DDR2 memory. I'm also going to be able to offer a more updated gaming performance comparison, focusing on more current generation titles since I won't be limited to benchmarks we ran in the past.
If there are any other requests, let me know, but expect this piece to be done early next week. I haven't touched the 360 since I got my hands on this Yonah board, so I may put in some quality gaming later today while some of the longer tests are running on Yonah.

Since you are looking at how a new architecture compares against another, I would like to see the variables kept as close as possible. To me this means Yonah should be compared to an X2 with 2MB total of L2 cache. You could do this with the standard clock speed for the X2 and with it underclocked to 2.0GHz to give everyone an idea of the performance of the Yonah arhitecture to the K8 architecture, as well as retail part compared to (close to) retail part.Also, for the power consumption part of the test, there are many variables at work. For example, there are the memory voltage differences, the differences in periphial power consumptions, and the chipsets. In fact the memory voltage was not even given for the Yonah setup. Furthermore, a mobile version of an X2 would use different transistors that consume less power. It is misleading and unfair to compare the Yonah setup to the X2 setup without even mentioning these differences.
To do a test comparing the two setups without mentioning these facts to the reader isn't fair. Since the article is comparing CPU architectures, the reader will assume that this means the different architectures account for the power difference. If it were an article comparing two systems or two products, then it would be fair because you want to compare them in the exact way that they will be used. Otherwise, you should explicitly state that multiple factors are in play.

What kind of a stupid comment is that?? Whatever is the reason, AMD has decided to put 1MB on X2, while Intel decided to put 2MB on Yonah.
The more fair comparison would be Yonah with IMC, that would kick the pants off X2 anyday.

What does "under load" mean for the power comparison between X2 and Yonah? If close to a TDP max, and idle power is low, then the added 16 Watts would make for a very cool running chip as you were suggesting of course. I just want to know how cool is cool. 27 Watts TDP?Anand Lal Shimpi - Thursday, December 1, 2005 - link
Sorry I wasn't more clear, under load is the same as it has been in previous articles - the system was running through our WME HD encode test, with CPU utilization pegged at 100%, but disk accesses are minimal (although the drive is still spun up).Take care,

Nice to hear more yonah vs dothan benchmarks.In the article you said that the logic used to dynamically resize L2 cache could be hurting performance. Is it possible that single core yonahs could end up performing better than dual cores in some situations?

How the hell does anyone know that Conroe/Merom has more pipeline stages than Banias/Dothan/Yonah?? Intel has never stated the pipeline stages for Banias/Dothan/Yonah. They have said 14 for Conroe/Merom, but for all we know it may be 14 for Banias/Dothan/Yonah. Some people say they measured it, but they all are between 12-14, and tells ABSOLUTELY nothing about the pipeline stages EXCEPT its in that range.Quiksel - Wednesday, November 30, 2005 - link
This is what I get for casual browsing anandtech on a slow wednesday night:as sad as this sounds, check out the "About" page with the staff bio's.... they are mega-old!
Vinney is still your fiancee in that blurb! :)

I would love to see how Yonah is compared to AMD Turion 64 CPU?? Can you run a performance test for it?vsridhar420 - Friday, December 2, 2005 - link
Yes. The real comparision would be with Turion.
