Vlade got those prices from pricewatch.com, but not carefully enough. The 2GB for $303 is a kit, meaning multiple modules. In this case, it means 8 256MB modules! That's pretty useless. For months now the smallest size module I'll buy is 512MB. The cheapest actual 2GB module listed is $780.

The 4GB for $191 is not even memory; it's some widget of some sort that's needed for added memory to some kind of server. It works with up to 4GB memory though. :)

You can get 1GB PC2100 modules for $125 though. I think I could possibly see my way clear to scraping by with 4GB for $500 vs. buying 2GB modules for $780.
 
i was pretty optimistic about what might come this summer, after hearing reports from MacB. Now, with a report like this, it is as though MacB. is making fun - yet again leaving the future in the hands of Apple!

They can still pull it off... and at this rate it will be a complete surprise to us all! (considering Apple has really turned out the lights)

Make it a happy summer...please?
 
Looks like Apple's planning for the future with this one.

It dosn't sound like an xStation more like a new xServer.

So maybe a new 970 xServer but maybe no Powermac yet.

We should trty not to get our hopes up to much :)

It really doesn't matter too much, but sometimes its annoying not knowing if things (especially harddrives) are being measured in Giga or Gibi bytes. People use Giga (which is supposed to be pronounced "jiga" even though I still say it with a hard g out of habit and people not understanding me) when they mean gibi and it all makes my head hurt!

huh? Gibibyte?! so all ram uses GiB? what? when? how?! where? and I'm having a hard time trying to speak the word Gibibyte!

THANK YOU

surely they have at least 2 GB dimms in decent production. i have seen 1GB so-DIMMS coming around soon, and if you can pack that into an so-DIMM, you can definitely fit 2 GB or 4 into a full DIMM.

I'm with you. Gibibyte? I personally don't see that word coming out of my mouth any time in the near future (unless I stumble into a CompUSA after drinking a six-pack of beer). However, I did find some info on the giga vs. gibi:

re:re:re:GiB

Harddrives and RAM and other data storage devices should be measured in Kibi/Mebi/Gibi/Tebi etc. bytes as they are always in some grouping of a power of 2, not a power of 10. Mhz Ghz etc. will probably never move over to a binary standard as there is no reason to measure clockcycles per second as a power of 2. Data transfer is normally measured in Mega/Giga bytes per second, but I think it will change (or should change) eventually, because if you have a 80 GiB harddrive and can transfer things at 100 MB per second you'll have to convert to binary from base ten in order to find out how long it would take you to transfer something, so it only makes sense to measure those in binary even though it isn't the current correct standard. Of course, since no one really follows the proper standards anyway, none of this really matters.

OOPS! Sorry, Thanks for correcting me. I hate when pricewatch does stuff like that
 
i still don't see why you can't measure hard drives etc. in GB and MB. in the same way that netweorks transfer in bytes or bits per second, a hard drive holds both bytes and bits. it's just how you look at it. and 8 bits isn't really any different than one byte. or whatever the equivalent is.

What happens if they're right? ;) :D

Personally I don't think the 970 will be first in Power Macs. Like people have been mentioning, I see them as a prime candidate for Apple servers, rackmounted or otherwise.

I admit, I cannot see most users needing that much space, but then again, I used to say the same thing about similar disk sizes.

My speculation: With the new machines Apple will come gunning for researchers, including bioinformatics. Imagine the entire human genome in searchable data structures in main memory.

Swap space? We don't need no stinking swap space.
 
No, there should be no problem !

Its logical I think, first I thought Apple will have 4 RAM slots paired with another 4 to get TWIN BANKING ....

That meant that they will have 6,4 GB/s which the PPC970 needs but if you have a dual CONFIG the two chips must divede the memory, so each chip would have only a connection with 3.2 GB/s, which is not very good !

So now I understand Apple will make 4 RAM slots for each Chip, but the Salt in this is that you will only have 2 RAM Slots per Chip because this two must be TWINED to reach the 6.4 GB/s, same on the other Chip, so at the end you can support both Chips with its needed full Bandwith !

Now you can also understand why in the rumors is said that on 4 SLOTs is a mark "dont use". This person which saw that board saw only a version of the board with one Chip !!! When you put two in it than you must take the other 4 !

Apple is a member in the HyperTransport Forum, now I know why ! :D

The Ram Banks will be connected to each Chip with Hypertransport to deliver the big Bandwith. And from there they will connect it with a Controller Chip.

Maybe now you all have the Key from the AMD-APPLE rumors Apple asked AMD for technical help because of there Hypertransport technology and connect options for Multiprossecor boards. AMD does this self or need it for there Opteron Systems ( I saw boards and technical datasheets of some opteron boards) Its a very good solution so I think we´ll see a nearly identical solution from Apple !

Therefore I say this rumors from Macbidouille are true ! But the information Person they have dont know much about technics ! For me so far the used technics are very very logical !

But what I heard I would say that this version of the Baord is (because of its Fiber connector) a Xserve Board. Without this port it could be a Powermac board.
 
You can always write a harddrive size in MB or GB, but you have to realize there is a conversion factor. Somtimes spaces are written without considering the conversion and are therefore bigger or smaller than you may think they are. Advertized Harddrive spaces ARE normally written in real Gigabytes (1,000,000,000 bytes per Gigabyte) however, when your computer reads it, I believe (I am not positive) It calculates the size in Gibibytes however writes GB. Before the prefixes were changed (1998) there could be either 1024 bytes in a kilobyte, or 1,000 and you rarely would know which one. Now you only know for sure what someone's talking about if they use the new base two prefixes as so many use the base 10 prefixes either way.

Anyway, this is all really off topic and we should probably get back to the actual thread.

Edit: Replaced incorrect Megabyte with Kilobyte

but for a market that demands it. it would be perfect. and apple has been trying to be "the one" in the industries that WOULD benefit from this.
 
We DO need a power mac of this caliber however I doubt that it existists

I'm 99% sure we will see at least one machine with PPC 970 announced at WWDC. Probably the xServe and the PowerMac. And other announcements about PPC processors in other machines. WWDC is only three weeks away and there still has been no 15" PB update.

I feels it in me bones. I think Apple is allowing some leaks to MacBidouille so we'll know something BIG is coming.

Why they picked MB, I have no idea. MacRumors/Arn would have been fine.
 
No, the P4 has no true 800Mhz Bus it handles 4 packages per cicle as far as I know the PPC970 does true 800 or 900 Mhz

that is why i said "TRICKED OUT". I know that they do not. they do a trick called QUAD PUMPING while apple does not
 
At first, I thought MB was doing a good job, but now I'm seeing more and more outrageous rumors from them.

I'm taking this whole 32GiB (weird to say..gibibyte :p) with a major grain of salt. I'll be happy to see a PPC970 that goes to 4GB(or GiB if you wanna get technical) this summer.
 
k sorry !

But the Apple solution is much better when you read my article 5 posts above
 
what's "truth"

What's the difference between doing 4 transfers per cycle on a 200Mhz bus, and 1 transfer per cycle on an 800 MHz bus. Effectively none, right?

And check your PPC970 facts - it has 2 unidirectional double-pumped (DDR) 32-bit busses, each at 1/4 of the CPU speed. You get 900MHz by double-pumping (DDR) the 450MHz bus on a 1.8GHz part. This is 3.2GB/sec read and 3.2GB/sec write.

The P4 is 64-bit bidirectional at 800MHz (200MHz quad-pumped), so the full bandwidth can be either read or write.

Guess who's "tricked out"???????????????????????????
 
Arn, are all these stories from MacB going on the front page becuase you have heard any kind of corroborating info or, just because they are fairly big/interesting news?

I would love it if all of these rumors are on the money, but if they were so close to the truth and coming out this early, wouldn't Apple legal be sending some fairly stern words to MacB? I mean they sent lawsuit threats to Spymac over iSync compatible phone lists being leaked. Seems to me that Apple would have tried to nip this in the bud several weeks ago if MacB were really putting out info that hit close to home.

Anybody else reading these "leaks" with a whole hand-full of salt?
