Yes, Hammer is NUMA. AMD's marketing department is trying hard to convince people that it's neither NUMA nor UMA but something in between. If the technical details that have been released are correct, then a NUMA OS won't be needed, but I guess we'll have to wait for some actual experiments to know for sure.
I'm guessing that dual ClawHammer boards will be pretty affordable since the chipset and sockets are the same and HyperTransport is easier to route on the board than old-style wide shared buses.
Your point stands in general, but the tests in this article were done with a single drive on an idle system. So I still don't believe that PCI had any effect on the results.
But soon enough everything will be in the chipset, so the argument will go away anyway.
Remember that the SATA controller is on a seperate card, it's not integrated into the chipset. So these number could (and probably will) change for the better when we see SATA built into the southbridge later this year...
I've heard this over and over, but I've never heard any justification for it. PCI is plenty fast for that disk, and it's hard to imagine that a new ns extra latency makes any difference in disk performance.
All the other drives in this review are either ATA or SCSI. So as SATA goes, this drive might be king of the hill by far.
Sure, it'll be king of the hill for about two months until Seagate and Maxtor come out with SATA versions of all their ATA drives.
PCI Express x1 is 250MB/s, but it also comes in x4, x8, and x16 speeds. Intel is planning to use PCI Express x16 for graphics cards; you do the math. Also, each slot has dedicated bandwidth.
Actually this event could very well be brought under the law that prosecutes illegal cable TV 'descramblers' (not to mention that damn DMCA nonsense). Just because the signal is being broadcast, and you are able to receive it, and you have figured out how to process it, does not give you the 'right' to view and/or record it (or something like that...)
I think the laws are different for broadcast, cable, and satellite TV. You can watch broadcast HDTV for free with a TV, so what's the difference in watching it for free with a computer? You can record broadcast HDTV with a HD-VCR, so what's the difference in recording it with a computer?
The FCC is the best rumor site on the Net. They've leaked PowerBooks, Blackberries, Palms, you name it. I'm surprised hardware companies haven't lobbied to keep those applications secret until the device is released.

Do they have some sort of shared cache so they can talk cache->cache without have to do a lookup in main memory.
Yes, I believe the coherence protocol allows direct cache-to-cache transfers.
Performance should be very good, although we'll have to wait until April for the official benchmark result.

Nope, because you still have to upgrade every year to get security fixes.

VMware or Virtual PC.
PCI-X is not the same thing as PCI Express, BTW. (I sense major confusion in the future.)

Did you mean Banias? I think it will compare quite well with Transmeta. Tejas will be a high-end, high-power desktop processor.
Hammer also runs 32-bit code at full speed.
On Linux the kernel detects sequential I/O and does the readahead automatically. So it's not really clear what Linux is missing.
The blurb didn't mention that the article is comparing disk schedulers, not CPU schedulers.
GSM crypto was broken at Berkeley.

You're allowed to record TV since it supposedly exists for the public benefit.
The broadcast flag is a proposal, not a regulation. But if the broadcast flag is issued, it sure looks like GNU Radio will be illegal.
40 times slower than realtime (on unkown hardware).
There are none. Check the Linux HTPC AVS forum for plenty of whining on this topic.
If you use session encryption then the key is different (and thus the ciphertext is different) for each download.
A monitor is a monitor. I wasn't suggesting that the Cinema HD replaces an HDTV tuner.
Hopefully Trolltech/IBM will support the standard SyncML protocol, which would give them iSync support "for free".
The Apple Cinema HD is a lot cheaper.
Never heard of swarming, huh? Alice can stream it to Bob who listens and forwards the stream to Charlie, who forwards it on to...
