Powerbook g5 coming after xmas - Page 2

Well, they cancelled Tejas on the basis that it didnt do 64 bit. I would think that their next processor should be 64 bit.

Do you even know what you're talking about? The 64 bit chips out there today are able to match and out perform any of the 32bit chips; the Xeons are no exception.

And as far as the G5s go...OS X.4 will be coming out soon and that will be a 64 bit OS. After that it's just a simple matter of issuing patches to existing programmes to take advantage of the 64 bits.

Well, the 64-bit Opteron whips the Xeon pretty badly in these reviews:

And btw, there's a 64-bit Xeon out too if you haven't noticed already.
Ever heard about Linux? With Linux you can take advantage of 64-bit computing today, and the advantages over 32-bit are pretty obvious:

Same goes for 64-bit Windows, although still in beta:

Not really, just have a look at this:

You can read right, or are you just too lazy?

Yay a G5 notebook! I've always wanted to brag that my lappy was so powerful I could only get 15 mins battery life!!!

In that second link they said they had MMX disabled in the P4, thats why the AMD narrowly wond, otherwise the P4 would of beat the AMD to death

OK, David, several things have to be cleared up:

You claimed that Sager produces notebooks that are faster than the top of the line Desktops. WRONG.

A top of the line Sager notebook cant even touch a top of the line desktop. Just look at the top listings from ORB Futuremark i dont see any notebooks up there.


As for your second claim, 64bit is useless, well, we all read the article didnt we. That pretty much clears things up


As for your dual Xenons whipping the ass of any 64bit chip. It all depends on what you're doing with these chips. Xenon chips are made to run server applications, thus, they will naturally be better at running server stuff like web serving, e-mail server, game server, etc. then there's Apple chips, they're mainly for work applications really, we're talking say movie making, video editing, photo editing/creating, rendering that kind of stuff since there's not many games designed for it anyway.
Anyway, i dont see Xenons riding the tops of 3DMark. The best ive seen with a Northwood core is on a P4C chip.

As for Kakaze, well, just one minor error you forgot to correct. By 64bit chips for the PC you mean Athlon64's right? Before A64, there was the Intel Itanium CPUs. They were 64 bit, couldnt game for crap and had to have specially made OSs for them because they couldnt switch between 32 bit and 64 bit easily. Everything had to be done in 64 bit, which was downright annoying. I cant see the Itanium beating any 32bit chip at gaming anytime soon.

And back to Davidlove, well, for the Intel beating A64 at Video Editing, well, P4's have ALWAYS been beating everyone else at Video Editing, it's on the Intel camp that they excelled at video editing something to do with the P4 architecture (to do with the netburst architecture and the MMX instructions from what i hear around here). It's intell success and not AMD's failure and it's certainly not 64bit that's holding back the A64's video editing abilities.
Just to tell you, when you run a 32bit benchmark the 64bit component of a CPU dosnt come into play at all as you have seen in snorre's links. They cannot be measured since a 32bit CPU cant run 64bit benchmarks.

As for your computer beating the crap out of Snorre's computer, well, try and match the benchies in his sig and post it up for all to see then post the amount spent on your computer. As for your 2GHz Dothan smashing a P4 EE, well, i would say not a chance unless the P4 EE's been downclocked like crazy and has had a crapload of stuff disabled. In those benchmarks, a heavily overclocked Dothan 2.0GHz CPU just barely managed to edge out the P4EE 3.4GHz and that's only in gaming benchmarks, when you do content creation, number crunching and the like, the Dothan gets owned.

even developers don't have access to the release cycle at apple. a jan release date is a rumour since the expo is around then. NO ONE outside of the product team really has any idea.. and yes it will be a crippled version of the desktop g5.. and frankly i wouldn't be surprised to see dual core g4 before g5 in the powerbook.

No, I meant 64 bit chips period. If it weren't for Intel's short sightedness concerning the Itanium they would be a serious contender as far as power for average users go. But as it stands they shot themselves in the foot and came out with a 64 bit only chip with no viable commercial operating system to run on them.

On the 64 bit windows and with 64 bit applications the Itaniums should be just as high up on the pole as the Opterons, Athlon 64s, and G5s.

64-Bit is useless until 64 Bit OS's are here with 64-Bit applications. And that isnt going to happen anytime soon.

64 bit is here with 64 bit applications.

yeah Linux. And the 64 bit version of Windows will be out by mid 05 along with a crap load of other 64 bit apps to go with it. Hell the beta version of Windows 64 is available on Microsofts website for testing.

Linux? Testing versions of Windows? And what type of improvement is seen on that, when you click the start tab does it open .000002 seconds. And does microsoft word make text documents in color .0004 seconds faster? I seriously fail to see what the advantage of 64-Bit is

64 bit is probably one of the most misunderstood concepts in computing. It doesn't magicially speed up programs. Athlon 64 chips are faster due to the evolution of the Athlon line, not because they added 64 bit support. Same for the G4->G5. It is a new generation of chip that works better, and just happens to support 64 bit.

So, what does 64 bit actually do? It lets a processor deal with memory larger then 4 gigs without special tricks. A 32 bit system with 8 gigs of memory has to partition it in two, and no single program can use all 8 gigs again without special tricks.

Now most people don't even have 1 gig of memory at this point, so why does it matter? This memory limit also applies to virtual memory space as well. One of the bigger advantages this has for consumers is in the game arena. Next generation games are likely to hit the 4 gig barrier on information they have in virtual memory. Games often decompress most of their resources and have them ready to send to the physical memory or video card to help with performance, instead of trying to decompress it all on the fly. This can be one of the reasons games are taking longer to quit, they have to clean up their virtual memory areas, and also do normal memory cleanup.

Regarding the G5 laptop. The reason it will be nice is due to the fact the G5 offers very nice performance jumps above the G4. 64 bit will just be a feature it has to prevent it from being obsolete so quickly. For those thinking it will be out before Christmas, well, be ready for a disappointment. Apple executives have said no G5 Powerbook in 2004, and also no new Powerbook refreshes until after the holidays. Regarding the cooling on the G5, I'm sure they won't have a huge problem with it. The cooling on the G5 desktops may seem insane, but it has one major goal. To be a quiet cooling colution. By putting the massive heatsinks on the processors, it created more surface area to then have very large slow moving fans in place to cool the processor. Much quieter then a tiny fan spinning 2 to 3 times faster.

The future PowerBook chip will likely be the new Freescale CPU, not a G5.

G5 are too hot, the iMac G5 has way more volume than a PB and is still hot. Its not a mobile chip.

The new Dual Core G4 is going to be insane. Dual Core, on core memory controller, I think either 400 or about 633 MHZ FSB the spec says, debuting at 1.5 - 2 GHZ.

Should be a monster and kill any G5 they could manage to fit inside a 2" laptop
