Titolo: [RUMORS] Nuovi Powerbook e Ibook: Isadora fermati

Pare che i rumors sulla presentazione a breve di una nuova serie di
Titanium e di iBook si stanno facendo sempre piu' insistenti. Isadora,
se non hai ancora preso l'ibook, io aspetterei almeno fino a fine mese.
Da 
www.macnn.com
MacNN sources note that Apple will officially introduce new speed-bumped
PowerBooks and iBooks later this month. The new PowerBook will feature
G4 processor speeds of 667MHz and 550MHz, larger harddrives (20GB/30GB),
a Radeon 128 Mobility graphics processor, Gigabit ethernet, and a
bundled AirPort card. The new Titanium PowerBooks are expected to be the
same prices as the current models. Apple is also expected to introduce
new speed-bumped iBooks with a faster 600MHz G3 processor, larger hard
drives (15GB/15GB/20GB), and more memory (128MB) as well as cut pricing
on its high-end machine combo-drive unit by about $100. Current models
are expected to be modestly discounted to clear remaining inventory,
after the expected October 16

Non riesco a capire se varrebbe la pena di gettarsi all'acquisto di un
vecchio appena scende di prezzo o se al contrario il nuovo e' nettamente
superiore.
Sono mesi che tentenno irresoluto se e su che portatile prendere. 8(
A dire il vero, se non avessi un cronico problema economico non avrei
dubbi ... ma ahime' ... 8((

 superiore.
Il mio *personalissimo* parere: prima dell'arrivo dei G3 ogni nuovo
modello era (abbastanza) nettamente superiore al precedente. Specie se,
come me, ti eri comprato il modello "low end" della serie in dismissione
approfittando del ribasso nei prezzi (faccio anch'io l'architetto ;-)
Quando sono usciti i "WallStreet" sbavavo su quello, 1a serie, che si
era appena comprato un amico. Il mio PB 1400 arrancava ma ho tenuto duro
(c'era ancora spazio per migliorie "sostanziali: infatti la serie
successiva aveva LCD piu' grandi ed erano scomparsi, definitivamente,
quelli a matrice passiva mentre modem 56k ed ethernet erano ormai di
serie).
Con l'arrivo del "Lombard" (2 cm di spessore e 2kg in meno dei
WallStreet) avevo tutto quello che mi interessa. E ci campo ancora
felice dopo piu' di due anni
Se poi tieni conto che sono ben pochi i programmi (tra quelli che
interessano "noi") a sfruttare Altivec...

Ma no, non e' minimamente per motivi professionali che m'interessa VPC.
Lo userei a casa e servirebbe anche a mio figlio che frequentante la
seconda elementare ... gli daranno in pasto Windows ... 8((
Almeno non vorrei si sentisse *del tutto* emarginato.

poterci usare VirtualPC per mio figlio.

Mai stato tanto felice che le poste ad oggi (ho venduto il mac il 26/9)
non mi abbiano dato ancora i soldi del contrassegno.. :))
Comunque si parla di martedi' :-PPP

a proposito di rumors, leggete qui:
"From TheRegister: 
Motorola names PowerPC G5 the 8500 
The next generation of Motorola's PowerPC processor, codenamed G5, will
be officially known as the 8500 and not the 7500, as originally planned.
It's a sign that Motorola is turning its sights even further away from
the desktop market - represented by the '7' in its chip nomenclature -
to the embedded arena - which is essentially what the '8' indicates. 
So too is Motorola's move to shift PowerPC into its Smart Networks
initiative, its edge-to-edge network applications platform. 
The G5's official name comes from Motorola's latest PowerPC roadmap. It
adds little to previous roadmaps, but we note that the G5 description
now has symmetric processing capabilities, Rapid IO support and will be
fabbed using silicon-on-insulator technology at 0.13 micron. That's in
addition to past roadmaps' mention of the G5's extensible architecture,
new pipeline (essential for the clock speeds Motorola has in mind), new
bus topology and its split into 32-bit and 64-bit product lines. 
Where once the G5's clock speed was simply "2GHz+", we now have "800MHz
- 2GHz+", suggesting Motorola may have scaled back its expectations a
little. Particularly since the G4 is still listed as "1GHz+" - a speed
it's still some way off (outside Apple's labs, at least). 
Motorola taped out the PowerPC 8500 - aka the G5 - last week and is set
to go into volume production real soon now at speeds of up to 1.6GHz - a
higher clock speed than AMD's latest-generation, 'Palomino' Athlon is
expected to ship at mact has learned. 
So claim sources said to be close to Apple, at any rate. The new CPU
will be offered at 800MHz, 1GHz, 1.2GHz, 1.4GHz and 1.6GHz, and while
the first two are nominally aimed at the embedded space - the others are
aimed straight at the desktop, we hear - we can see Apple using them as
to transition over from the top end G4, the PowerPC 7450. 
Getting to those clock speeds involved increasing the G5's pipeline from
the 7450's seven stages to ten. The part is capable of exceeding 2GHz,
we're told, but the initial batch of shipping clock speeds suggests that
the either the yield or the stability of 2GHz parts isn't high enough to
ship chips at that speed. 
High clock speeds also mean high power dissipation, but Motorola has
nicely countered it by fabbing the G5 using silicon-on-insulator
technology, leading to a power dissipation of 26W at 1.4GHz, our source
tells us. By comparison, the 7450 draws 14W at 533MHz. Our source had no
word on what process Motorola will use for the part, but we reckon 0.13
micron with copper interconnects. The transistor count will be 58
million gates. 
That's said to be twice the 7450's transistor count, which makes us
wonder what Motorola will do with the extra gates. The longer pipeline
and additional instruction units will account for a lot of it, but we
also wonder if the chip will feature a built-in memory manager,
something Motorola has been talking about of late. 
Beyond far higher clock speeds, the G5 will be a full 64-bit chip, but
will support 32-bit addressing at full speed. The part will also support
multi-processor configurations. 
The G5 will sport a 400MHz frontside bus - like Intel's Pentium 4,
though its performance could be limited by whatever memory technology
Apple connects to it across the system bus. 
Speaking of which, we hear work is progressing on a new chipset,
designed for the G5, which will support up to 16GB of DDR SDRAM. What
type of DDR, we don't yet know. The chipset's south-bridge part - ie.
the chip that primarily handles I/O - will support USB 2.0 and the
Bluetooth wireless connectivity standard, in addition to the familiar
1394 - up to 800MBps? - and 802.11 (aka AirPort). 
Incidentally, given Apple's recent statement of support for AMD's
HyperTransport bus technology, and its presence on the HyperTransport
Consortium's founder member list, we reckon that the new chipset may
also use HT for chip-to-chip communications, but as yet this is
unconfirmed. 
Bugs fail to knock PowerPC G5 off schedule 
Motorola's next-generation PowerPC processor, the 8500, aka G5, may yet
make it into new Macs early next year, Apple sources have claimed. 
At issue are recent claims that Motorola is having problems with G5
yields, with many clocking way, way below the 1.6GHz the chip is
expected to reach once it ships. We can't say we're entirely surprised -
yields are always very low in the early days of a new processor,
particularly those based on a new iteration of an architecture. 
Yield problems will be very bad now and slowly get better through the
life of the chip. Even now, we're sure Motorola is trashing a small
percentage of G4s that don't make the grade. At some point a balance is
reached where a sufficient number of dies that work at the right speeds
to make volume shipment economic. 
That point is echoed by our source. Current problems apparently include
clock multiplier and external (L3) cache coherency issues. The former
has been fixed, the latter still being tackled. Other bugs may yet
emerge, our deep throat warns. 
Again, we'd be very surprised if that wasn't the case. Apple and
Motorola will be finding bugs right up until the chip ships inside Macs.
What matters is that none of the glitches significantly impact
performance. 
If that happens - or if yields don't improve as expected - the G5's
launch could slip from early 2002 to mid-2002, with Power Macs based on
the part being announced at Macworld Expo New York rather than the San
Francisco event. Apple CEO Steve Jobs, says the source, is shooting for
a January launch. 
We can see Jobs doing so, but announcing that top-end models won't ship
until February or March, much as he did this year when he unveiled the
733MHz and 667MHz Power Mac G4s based on the second-generation G4-class
PowerPC, the 7450. 
Says our source: "At this time last year, 7450 yields were not much
better than what G5 yields currently are." 
Still, it's clear that the G5 won't go into volume production for a wee
while yet. Previously, we heard that production would ramp rather more
quickly than it now looks like it will. But that's the nature of the
processor development beast and our source can't be blamed for their
past enthusiasm. ® 
We don't know the ship date either, though we've been told that Apple is
shooting to get boxes out for a January launch. If Motorola is sampling
the G5 now or is about to, then we'd estimate that volume won't begin
until early to mid Q1 2002, which would enable Apple to launch at
Macworld Expo San Francisco and ship the higher end boxes in, say,
February, as it's done before. 
Apple will launch Mac OS X 10.2 around the same time, we're told, and
offer it as a 64-bit version. To do so would surely limit users of older
hardware to 10.1 and its updates, but that hasn't stopped the company
making such moves in the past. The G5's 32-bit support will allow apps
to be carried forward, and developers have been told they will be able
to make '64-bit clean' apps with a simple recompile. 
If our source's claims are accurate, the timing would be right for
Motorola to unveil the new chip at this autumn's Microprocessor Forum,
on 15 October. "

 felice dopo piu' di due anni 
Hai ragione. Un  mio amico ha appena comprato un bellissimo (imho)
Powerbook g3 333 usato.  Sembra nuovo. Uno schermo che e' una favola (a
14.1). Piu' sottile di molti portatili venduti quest'anno. Insomma: per
l'utilizzo normale e' ottimo.
Unico difetto: l'hd relativamente "piccolo" (solo 4 giga). 


 assurdo...
relata refero ^_^
ciao
crob

 Infatti sto aspettando un nuovo "Tavelstar" da 10 giga per $99 ;-)
Ottimo. E' facile l'installazione interna? (mi sembra sia sotto la
tastiera, vero?)
Ciao,


 tastiera, vero?)
si: la sollevi, tirando una linguetta estrai la "slitta" dell'HD, sviti
le quattro viti (torx) che lo tengono, stacchi il connettore e fai tutto
il processo inverso coll'HD nuovo
Prendendola con molta calma ci vorranno... 5 minuti?

Ciao,
Scusa la domanda: ma cos'ha in meno del Pismo? 
A parte l'hd piccolino, mancano le FW per caso?
Lo schermo e' uguale, lo spessore pure (non e' quello dei "mitici"
Lombard, per capirci)...

Vuoi dire dei "WallStreet", visto che stiamo parlando proprio del
