The Hexus article is just a summary of their results along with several inaccuracies.
If you're I/O bound by your threads in any way, you can hit problems (all threads touch the MCH, then there's a 266MiB/sec bus link to the I/O processors to cross, then the data hits disks or network hardware). If you're memory subsystem bound in any way, especially on a majority of compute threads, performance is likely gone.
This is misleading. First off, the MCH is a 6.4 GB/s link so I dont understand how it could bottleneck I/O even if you're compute bound. The 266 MB/s IO bus is for legacy peripherals (USB/serial/SATA). Considering SATA-I (what the ICH5R supports) is 150 MB/s per channel, and USB is 400 Mb/s I cant see how this is a big problem. If you want fast (SCSI/FibreChannel/SATA-OII HW raid) disks and network, there are PCI-X 64bit and PCIe x4, x8 slots that you can have your important I/O subsystem hanging off of.
I think a point to consider is that in 64-bit mode the Athlon64 is enabling 2x the number of registers. This is why only a few applications (that dont have any reason to be memory limited, but are register limited) get the speedup.
64-bit addressing should be slightly slower than 32-bit addressing because of lower code density so it is not likely to be the cause of speedup.
Of course all these websites are clueless to these things.
What are we going to have to do to convince "ordinary users" to visit WindowsUpdate once in a while?
I once lost a bunch of work because I was doing some stuff in illustrator and forgot to save before leaving the machine on overnight. Windows update decided it needed to reboot to install the updates and I lost a whole afternoons worth of work.
I usually do work on my linux box using emacs and openoffice, so not saving religiously has become a bad habit.
Xbitlabs found that Venice uses slightly more power than Winchester (the older 0.09u core) around a month ago. They tested cores at the same speed unlike Lostcircuits, and while LC is a good site, xbit is generally better. Not to mention the guy at LC blew up a few MBs before "finding out" how to do his measurements. Aslo Xbit is the only site I know that has an accurate video card power consumption database.

Add this to your/etc/apt/sources.list and youre good to go.

I like 7.0, but its an absolute pig compared to gpdf/xpdf.
RTFA and then check out the comments. There is a moron AC (who happens to love gentoo) who thinks recompiling the toolchain gives him faster binaries. Another AC spends a great deal of time trying to explain that this is not possible before the flaming starts.
Fun stuff!
If all the OS's are configured similarly (which the author didnt say they were) they should perform the same except for the 2cpu tests. There simply isnt a whole lot for the OS to do in these tests other than retrieve stuff from disk or something. The 2cpu tests are definitely interesting.
While privately built rockets (especially unmanned) are going to be much cheaper I dont see how the civic ferrari analogy holds. A civic is more reliable precisely because of the number made. Sell a million or so cars a year and you have a vested interest in not having reliability problems, and a LARGE sample to draw from for possible improvements for next years car. Ferrari meanwhile has a much smaller sample from which to identify problems. Looks like this CEO is good at shovelling shit just like the rest of them.
http://www.hushtechnologies.net/ has some excellent boxes. Theyre not cheap though, but very good and silent at around ~21 dB @ 1 meter. Google for reviews if youre interested.
Do you know if OLED handles the problem of LCDs where they have limited brightness bits. See David Kirk (Nvidia's chief scientist) blurb here :
http://www.extremetech.com/article2/0,1558,1745058,00.asp
LCDs only have 5 to 6 bits of brightness levels, while CRTs have 8. What about OLEDs?
Pathsync looks interesting for directory synchronization. Is there something to do this between two linux clients or windows and linux that is rsync or cvs based. Preferably GUI clients or easy to use ones. I need windows > linux backup and linux laptop > linux backup.
I saw backuppc in the debian archives, but I'm intersted in user opinions as it is always so much better.
Thanks!
I'd really like to know if any of these services offers email backup. What happens when a disk fails? Surprisingly I havent seen it mentioned in any past gmail discussions by the/. crowd.

Yeah the 82801ER and 6300ESB do not connect to the PCIe or PCI-X devices. They connect to the MCH through a separate interface. Just look at the PDF.

All that being said, the CPU itself is a dog.

Girlfriend or not, spending $200 on merchandise is lame.
Liar! It works for me.

Yeah, youre right.
Think of it like an RPN calculator. The arguments follow the function. STart from the deepest nested function and walk outwards.

Why is irony so lost on some people?

Hey dood great post, too bad I dont have any mod points.

Interesting to see the systems relegated to the garage/basement....
