Ars Evaluates Core 2 Duo in Latest System Guide
RevDobbs writes "I always take a peek at the Ars Technica System Guides before white-boxing my next PC. Well, today I hit the site and see that they recently published their first post-Core 2 Duo System Guide." From the article: "The new Intel Core 2 Duo processors bring a swift change to the Hot Rod, making the lifespan of Socket AM2 very brief in the Hot Rod. Performance from the Core 2 Duo (aka, Conroe) appears to be excellent in all regards, from pure performance to heat output. Overclocking prospects also look excellent, with an overclocked Core 2 Duo being an amazingly fast chip for the money."
Intel is doing a lot of things right. This is a common core from laptop to server. Keeping it simple--AMD has a lot to worry about. I wonder about what a giant leap in energy issues would do. For example, greatly reduce power reduction at the transistor level. The whole issue of power usage would go away--and you'd have Intel and AMD racing for performance as they did in the late 1990's. The Conroe is a great processor, but a lot of effort went toward being miserly.
And I'm still waiting for an architecture change. How about finally retiring the byte as a base logical unit? In return, just use the bit, or whatever word length the machine is.
Newsflash: A lot of data is still 8 bits wide.
And for your information: Processors like the x86 series are not byte addressable. They usually load a cacheline and the processor fetches the byte you want.
So instead of doing
movb (%rax),%bl
You'd have to do
movq (%rax),%rbx
andq $255,%rbx
Worse yet, if you want the [say] 5th byte of a 64-bit word...
movq (%rax),%rbx
shrq $40,%rbx
andq $255,%rbx
That's clearly a winning idea!

Someday, I'll have a real sig.
No, actually, to use the full power of the God Box requires something with fewer root exploits and journaling file systems...
I just checked out the system guide for the "Hot Rod". Since the Asus P5B Deluxe motherboard has Dolby 7.1 channel audio on board, why would one need to spend $110 on a separate audio card? Is there really a difference between on-board audio and the audio cards that are mentioned in this article?
You're out of touch. Most of the boards out there that say they support Conroe actually don't. They're either very unstable or have features that don't work with it, and/or require BIOS updates in order to run with a Conroe chip at all. Even then there's no indication of how stable they'll be. As someone else pointed out, you can buy very fully-featured motherboards for AM2 for about half the price of a Conroe board, and they'll be a lot more stable than most of them too.
The crazy thing is that, despite being on a seemingly ancient 90nm process, the AMD chips still seem to consume less power at idle that the core duo, at least according to Anand. That's why I'm currently sticking with my AMD's in my 24x7 boxes, which spend 99% of their time idling away.

Umm, what do you mean be "wasn't journalling until v5". It's always had a transaction log file from the initial release. Check here for NT 3.1.

The idea is it can rollback partially completed transactions and recover from bad shutdowns. Also it can do it quickly without searching the whole filesystem for inconsistencies. That's the whole point to NTFS.
