The G4 is more than ample in a notebook.

While we've all see the adds for "faster" PC notebooks with a slimline profile, there is something that very few people make note of, and that is: Just how do the PC makers get a "3 Ghz" processor in a laptop. You can only do one of two things. First thing you can do, is to take a processor, and run it in a "power save" mode, which essentially robs the processor of anywhere from 1/3 to 2/3 of its capability, so all of a sudden that P4 3.0 laptop is starting to look a lot less attractive. Or, you put it in the aforementioned beast of an enclosure. A colleague of mine who just spec'd out a Dell laptop managed to get it to just shy of 10 lbs. I don't know about you, but I don't want 10 lbs of laproasting computer. And even at 10 lbs, that computer can't compete with a desktop. So I'll stick to a 1.67 GHz G4 any day so long as the enclosure is the thing of art that it is currrently.

i agree only to a certain point.

i do not pretend to need a faster processor..but the FSB dissallows heavy A/V work. when i say heavy i mean heavy in terms of my amatuer needs. i want to run Reason and Logic at the same time with a few (read - more than 2) virtual instruments in logic and a lot of instrments in reason (reason is really efficient processor wise).

now, playing back more than 5 tracks in reason which are moderatly active and recording a track at the same time causes hiccups in many cases. while this WAS understandable...it no longer really is since the programs are getting more advanced without a large jump in the computers performance. i am probably going to buy a 17 or 15 inch powerbook. they look like they will run well, and they undoubtedly run more quickly than my 450 power mac. but my use of Audio programs will only get more intense and i want to know that the computer will be able to record or play back tracks without hiccups.

(yes there is a freeze fucntion in logic, but if i HAVE to run to that now what happens in a year or so...)

I agree the new G4's are plenty good for me. I also wonder about the G5's battery life!
 
G4 not just as fast as G5

Pale Fire said:
Not much... The G4 does have something of a rather sad FSB from what I hear, but aside from that there is no real gain going G5. It is not that much faster.

I've seen this sentiment more than once.

In July, 2003 NASA did a study which found that


G5=.127 MFLOPS/MHz
G4=.104 MFLOPS/MHz

That's a 22% speed difference.
And it's worth stating that the 2 GHZ G5 was 32% faster than a 2 GHz P4.

This was a study of MFLOPS because that's what NASA was concerned with.

Integer performance:

G5 is inferior to the P4 clock for clock, but it is compares favorably to the G4 just because clock speeds are higher.


http://www.thinksecret.com/news/wwdc03g5.html
http://www.theregister.co.uk/2003/06/25/apple_denies_fiddling_g5_xeon/


What sort of applications use integer/floating point:

"Most performance measures look at the processor's ability to process integer data: whole numbers, text and the like. This is perfectly valid, because most processing is done on this sort of data. However, intensive floating point applications, such as spreadsheets and some graphics programs and games, make heavy use of the processor's floating point unit (FPU)." [from pcguide.com]

Also, Intel's dirty little secret was that they had a worse problem when comparing the P4 to the P3!

"Clock-for-clock, the Pentium-III™ is faster than 2003-vintage Pentium-4 processors, especially for floating point calculations. However, the P-III tops-out at 1.4GHz, while the The P-4 offers faster clock and memory speeds. You can argue that a 1.4GHz P-III is faster than a 1.7GHz P-4; however, the P-4 is available at above 2GHz." [http://ourworld.compuserve.com/homepages/r_harvey/doc_fpu.htm]

Don't we all? 😉
We'll see something similar to those specs in a PowerMac before they appear in PowerBooks - I'll reserve my judgment until that happens.
 
Ok, so I keep reading all these posts about people whining about a lack of G5 PowerBook. Can someone honestly tell me WHY they think they *need* one?

I'll tell you who truly need one: Musicians. And I'm not talking about the "I've toyed around with GarageBand once or twice" guys.

Computer based music making is one of the great Mac strongholds, along with design (print/web). Musicians tend to prefer Mac over PC, and notebooks over desktops. They wanna be able to make music on the road, and they wanna be able to play live or DJ without having to lug a minitower around.

Unlike design applications like Flash, Photoshop etc, music apps are really CPU intensive, and when I say intensive I mean from the minute you launch until you quit you keep that sucker at 80-90% at all times, fans whirring, room temperature 2 degrees above normal.

You need a fat throughput between RAM, CPU and HD to keep all those audio tracks and virtual synths playing. Like games, music apps tend to aim at high performance machines and evolve according to whatever is top of the line at the moment.

PC notebooks are keeping good steam; the Centrino gave the notebooks a good relative speed boost, you've got a 400 or 533 MHz bus speed on all of them, and basically they aren't lagging that far behind the Windows desktops. They remain decent music platforms, performance wise. Which means you can move material between your desktop and your notebook without having to find out that the damn notebook will choke on it a few bars into a song intro.

But the discrepancy between the G5 desktops and the G4 notebooks is quite ludicrous. That 167 MHz bus ain't gonna cut it no more. And when PowerBook G4 users keep downloading tracks made on Windoze machines only to find time and time again that their PB is too slow to play it, they're gonna start wondering what the hell is going on.

Notebook PCs range from smaller than the 12" PB G4 to friggin' huge (think Dell Inspiron XPS), and the smaller you go the more performance you have to sacrifice. But Apple is just not giving us that choice, mainly due to design snobbery. They've already proven they can stick the G5 in something considerably smaller than the desktop G5, namely the iMac G5. But everyone's so spoiled with the paper thin, light and silent G4 PBs being top of the range, they wouldn't believe their eyes if a heavier and thicker machine was introduced, 'cos they were half expecting Jobs to pull a G5 powered iPod Shuffle out of his breast pocket...

Yea but ur missing the point. Centrion 2.1 ghz is way faster than any 3.4ghz penitum 4 and stay cool and hardly makes noise. No its time for apple to realse somethin new. 1.67ghz g4 is a joke and has to be at least 2.3ghz g4 to even be comparable now!
 
Moved: A word on Apple Privacy

Hey guys, this revalation came to me today as I was pondering a business idea of my own. Thought I'd share and see what you think:

I was thinking about Apple's ongoing image as the "good guys" in a world of evil PC companies, and why on earth they would suddenly damage that with a silly lawsuit just to protect their secrets (suing the guy who leaked shuffle/mini info). I mean, the shuffle and mini are new apple products, and leaking the info really wouldn't hurt sales in ANY way, as they are even in their own product categories.

That got me thinking. What if Apple did this as a precedent thing? What if Apple is developing (or stockpiling for production) something right now, and really doesn't want people talking about it. Seems plausible. But what product? It would have to be an upgrade to a current product, where prior knowledge of an update would hurt sales of the current model being sold (drastically). Another factor to consider is that it is most likely going to be a power user product. Reason is, the only people that really pay attention to update rumors are the people who actually need what's being updated. Power users tend to dominate these rumor sites, and Apple knows that power products are the most succeptable to sales drops due to leaks of updates.

Jobs reinforced throughout the keynote that 2005 is "The Year of HD." My personal opinion is the product in question is a G5 Powerbook with an HD screen. This will be released alongside Tiger, and a speed bump for iBooks.

Why do I think this? Okay let's think from Apple's side. They will at SOME POINT release the Powerbook G5. It's pretty much inevitable. When they announce it, they will have to start shipping at that point, as nobody in their right minds would buy a Powerbook G4 after the 64-bit processor and 64-bit OS are announced together. So Apple will have to stockpile enough G5's after it's designed to feed the demand, so as to not let Powerbook sales decrease. In my belief, Apple has already designed the notebook, and is stockpiling them. This is the reason for the rough estimate "sometime in the first half of the year" for Tiger.

One might say, "Well, why the hell would they do a speedbump and contract a new 1.67 ghz processor just to dump it a few months later?" The answer is they're not dumping anything. Remember the iBooks? Yeah, those G4's aren't gonna go to waste. This will also satisfy the market of power users who want their computers to be differentiated from the increasingly appealing iBooks.

Apple seems to be going for the jugular this year, and wants to steal as many windows users as possible, while not losing a single apple customer. The shuffle and mini are testaments to this. Apple did the speed bump to pacify the power users who were beginning to get ancy. With this newest release (probably at WWDC) you can expect a complete state of shock throughout the computing society. Consumers will be clammoring to get their hands on a 64-bit high-definition laptop, and pc manufacturers will be stupified and scrambling to cut their losses. 😎

That's a good idea...but I think a PowerMac update @ WWDC is far more likely than a PowerBook update @ WWDC.
 
El Duderino said:
THEY'LL UPDATE BOTH. MUAAhAHHAHAH!!!!!11!!!oneone!

Yeah, I think that's a definite possibility. I'm thinking Apple will exceed everyone's expectations this year. I just hope they release a new powerbook with Tiger, as the OS is the only thing I'm waiting for to buy a laptop. I'm halfway into the semester at a university that REQUIRES you have a laptop. Yeah... dragging my iMac and a generator to class everyday is getting old 😛
 
Here's what I am waiting for...

I currently own an '01 15.2" TiBook G4/667, and I have been waiting for Apple to significantly improve their 'books enough to replace it, but it has yet to happen. I am looking forward to some things to truly make it worthwhile. Here are the things I hope are to be introduced by the end of summer (if they are, I am 110% ready to get a new 15" PowerBook):

Processor: 90nm 1.8-2.0GHz Freescale 7448, with its faster 200MHz bus and 1MB cache. It has been said before, and I will say it again: the 7447x sucks, and needs to be replaced! Dual-core would be nice, but this is but a pipe dream for another year MINIMUM. Plus, I still believe G5's won't make the cut for a PB.

Screen: A move to 15.4" TRUE Widescreen (none of this 15.2" bull), brighter with a better viewing angle, and WSXGA+ resolution - 1680 x 1050. Our screens are an utter EMBARRASSMENT compared to Wintel offerings.

Graphics: A move to PCI-X (or PCI Express). Since the X800 Mobility is too hot/large, it is pretty much out of the question. BUT, get rid of the Mobility 9700, and throw in an X700 Mobility or Geforce 6600 GO with 128-256 megs graphics RAM. They are plenty cool and use nearly as much power as the current Mobility 9700, yet are much faster (up to 2x faster in Windows benchies).

Hard drives: Offer 7200 RPM drives. Plain and simple. I could live with some extra heat/noise for the increased performance.

RAM: Move away from DDR333, and get on over to DDR400 already! Or maybe even make the leap to DDR2-533. Hell, if they can get PCI-X in, they could do this! Latency on DDR2 has gone down dramatically as of late.

OS: Mac OS X 10.4 "Tiger" pre-installed.

Battery: A battery using this new technology I JUST read about a couple days ago (but can't remember where), that makes the batteriescheaper to make, last much longer, and recharge much quicker. I wish I could remember where I read this, maybe on Geek.com?

That is basically what I am looking for, and hope to GOD to see these improvements (OR BETTER!) in the next revision. Here's to hoping! -JB

Screw that. Apple needs to put at least a single core MPC8641 under the hood at 1.8-2.0ghz and cut free the other components that would be taking up space, power, and heat profile. That single move would eliminate an external system controller, allow the user of cooler, lower-power DDR2 RAM (up to 667mhz), eliminate the bus bottleneck by using the on-die memory controller, allow SATA interface for drives (if there even are 2.5" SATA drives), move the network controller on-chip, and keep the superior Motorola implementation of the vector unit while adding dual-precision capability and a second vector processor. Oh, and the 1MB L2 cache doesn't hurt.

Screen: A move to 15.4" TRUE Widescreen (none of this 15.2" bull), brighter with a better viewing angle, and WSXGA+ resolution - 1680 x 1050. Our screens are an utter EMBARRASSMENT compared to Wintel offerings.

Not unless you're talking about the high end, they're not. I've seen plenty of bad, bad LCDs in Wintel laptops, no matter how shiny the specs look on the box or on paper. Besides, for a lot of people, WXSGA scale resolutions on a mere 15" screen are going to be way too small to be legible.

Graphics: A move to PCI-X (or PCI Express). Since the X800 Mobility is too hot/large, it is pretty much out of the question. BUT, get rid of the Mobility 9700, and throw in an X700 Mobility or Geforce 6600 GO with 128-256 megs graphics RAM. They are plenty cool and use nearly as much power as the current Mobility 9700, yet are much faster (up to 2x faster in Windows benchies).

Windows benchmarks are based on DirectX 9 performance for the most part, so they're not exactly going to be indicative of how the card would perform in a system based on OpenGL and Quartz.

From PCMag's review:
We tested the X700 in a 2-GHz Pentium-M CPU, with 512MB of system memory, a 1,680-by-1,050, 15.4-inch display, and 128MB of graphics memory. We used three demanding 3D games: Doom3, Unreal Tournament 2004, and Far Cry, at a resolution of 1,280-by-1,024. Doom3's frame rate was down around 21 fps, whereas UT 2004 and Far Cry were closer to 30 fps, a barely passable speed for first-person shooter games When we enabled anti-aliasing and anisotropic filtering, only UT 2004 stayed up around 30 fps, whereas the other two games' frame rates fell below playable levels.

So, at the resolution you want, the X700 wouldn't power even UT2004 as well as the 1.5ghz PowerBooks with Radeon 9700s runt it at their native resolution. Oops.

Hard drives: Offer 7200 RPM drives. Plain and simple. I could live with some extra heat/noise for the increased performance.

Can Apple live with the inventory issues?

RAM: Move away from DDR333, and get on over to DDR400 already! Or maybe even make the leap to DDR2-533. Hell, if they can get PCI-X in, they could do this! Latency on DDR2 has gone down dramatically as of late.

See my comments on processor.

Battery: A battery using this new technology I JUST read about a couple days ago (but can't remember where), that makes the batteriescheaper to make, last much longer, and recharge much quicker. I wish I could remember where I read this, maybe on Geek.com?

I want the thing, you know... The THING! That one that makes it faster and cheaper, right? That one!
 
yeah, the 167 mhz system bus is a joke....my dell pentium III 550 mhz had that in '99 🙄 people don't realizes how much the system bus affects overall performace. i'd bet that a 1.6 ghz g5 with an 800 mhz system bus would smoke any g4 on the block. the cpu isn't the only thing using the system bus...EVERY component in the system that has to access main memory at some point, which is pretty much all of them, use it. the powerbook has all of these amazing throughput options, and then this decrepit system bus? what's the point? i, for one, would love even a 2 inch thick powerbook g5 at 1.5 ghz. they could whip one up in a couple of weeks and market it to mobile creative professionals while still selling the old g4 powerbooks to keep the ultra mobile crowd happy. you have digital photographers editing 22 megapixel photos on the powerbook 17" right now...i can't even imagine how much money that wastes in time... plus, if apple had all their machines on the same processor, it would encourage more developers to optimize their applications, which has been shown to cause a massive increase in performance.
 
I understand that people want a fast G5 powerbook. I understand that some people don't want to invest in another G4 powerbook. But all i gotta say is I just got one of these new sweet machines, and i'm playin all my games, running all my software, and everything... this machine is sweet. It is a very snappy and responsive computer. Multi-tasking is no joke. How could this computer be so fast with such a pathetic bus?

Answer: Bus is NOT pathetic. You guys are caught up in a number game. Get enough RAM, and a G4 will measure up to a G5 in just about every real world test (of couse not 64-bit FP precision)...

Seriously, it's a number game. This bus architecture is FINE if not GREAT for the 'numbers' it portrays. World of warcraft is a memory swapping machine, yet i see no lag...

I'm telling you guys the bus is fine. Just yesterday i streamed in DV while watching a movie and downloading some demos all at the same time... this system is nice. I have not been disapointed.
 
i think its kinda obvious we're going to see a new form factor alongside the G5, so it will take days/months/decades to get a G5 working in a portable with no problems... and then a few more months for Jonathan Ive to get an uber sexy and sleek new look.

my guess is that after all this Alu PB 'pitting' and warping problems they will switch to something light and tough. ie, Carbon Fibre. but a lot of people are saying this so im no psychic.

like Duke Nukem Forever. when its done. i have no problem waiting, but i think the PB line is acting more like the iBook like. its kinda like;
eMac=iBook
iMac=PB.
PowerMac=PB G5?

meh...
 
Patience is needed. Apple will advance the PowerBook as soon as it's technologically possible. It may or may not be a G5 that is next. Steve is just as anxious to please as we are to receive.
 
Ha ha. You said "Centrion"

I am crapping my droors reading this, This is quite possibly the most ridiculous post that I have ever read on this forum. A "centrion" (read, centrino), is a processor designed for laptops. It is not faster than a P4. It's not meant to be, it's meant to be placed in the thin PC notebooks and is essentially an even more anemic version of the 686 stepping that the fatter notebooks are based on, it runs at a lower clock speed to save on heat.

The 1.67 GHz G4 is not the joke, you are.

Not quite. Centrino is not a processor, it's a marketing term. You're talking about a Pentium-M. A Pentium-M and Pentium 4 are completely different in terms of architecture - the -M is NOT a clocked down version of a 4. It's loosely related to the old Pentium 3. There are all the comparisons you want on Ars Technica, but clock for clock the -M is faster than a 4. Too bad the -M only goes up to 2.1Ghz or so. Google all the benches you want, here's an interesting one:

Conspiracy theory

To the poster who suggested, quite thoughtfully imo, a connection between
Apple threatening the tech reporters for leaking mini/ipod stories, and an effort to protect a imminent release of a G5 notebook...well

In May 2004, while I was deciding whether to buy an iMac G4 (and switch) or stay w/Wincrap, I tracked down an Apple rep at a university (which will go unnamed to protect the rep) and he cautioned me to "Wait...I can't say anything directly because Apple keeps this information under wraps...but it is rumored that a replacement will be released at the WWDC."

So I waited. When it wasn't released, I seriously considered buying the G4, but waited a few days and as I recall, Apple stopped shipping the G4s before I could get off the fence, so I ended up having to wait at that point. (The wait was worth it, btw).

This is just anecdotal evidence in support for the poster's suggestion that Apple probably wouldn't want to squash existing sales with premature rumors, The premature rumors about the G5 iMac certainly kept me from buying the ole version.

From a First Amendment POV, I do find the effort to prosecute reporters repulsive, though. I think Apple should drop it, and control the leaks internally.
