Re: 2nd CPU Why on earth?

I believe the latest and greatest PB suffers a major bottleneck between the main memory and the CPU. If so, does that not mean that your dual CPU's would choke the bottleneck faster than a single CPU and yield little performance improvement.

Unless you actually have one of the new TiBooks (rev. c) you have no clue. The L3 cache more then makes up for any kind of bottleneck between the memory and cpu. :rolleyes: ya nit. :p

I can see how L3 can speed up the 'snappiness' of the system for relatively (w.r.t. L3 size) small operations. But, how would an operation that significantly exceeds the size of the L3 cache, such as a large rendering, benefit from increased L3 cache, when ultimately the data in the main memory has to get to the CPU to be processed?

So, if rendering and other massive data processing applications are really the only PRACTICAL reason for employing dual processors, and if large L3 cache, in lieu of a fast FSB, fails to help massive data processing applications, why get a dual PB?

25-30lbs (and all the other 'features' you listed) goes against everything that a laptop computer is. If you want to lug around a system, just get a carry strap setup (there are computer places that sell them for people to take their systems to LAN parties). :rolleyes: Or, just get a new tower, LCD screen and set it all up on the power grid.


Yes, you ARE an oddball wanting a monster 'portable' computer like that. Especially since Apple pretty much has what you want in their tower (or eMac as suggested in jefhornyfield's post :eek: ;)).

There is a big difference between being able to carry a computer somewhere,and being able to use a computer almost anywhere,quickly and effortlessly,without damaging it because it accidently rolled out the back of a truck!
Would you buy a Dual Ghz Quicksilver G4 that had every feature a tower had,only it was built into a oversize powerbook style,ran on batteries,and all packing it up to take somewhere meant was to close the 19" screen and disconnect the peripherals?Sure,I can move my tower and 19" Sony Trinitron around,but add a UPS and a 120 lb marine battery to that and things get a little less than practical!
The only real reason I can see for not manufacturing a "jumbo" portable,is that it would completely cannibalize both notebook and desktop sales by providing the best of both worlds in one unit,and therefore making owning one of each quite uneccessary to most people.
Someone will do it someday,then I will buy it,even if it's a.....PeeCee!

Sorry,kind of off topic,I know.
Back to the world of squeezing it all into an ultra thin CD case,and pondering as to where to squeeze in the last 40 of the 347,986,943,012 transistors.....
 
i guess by now some serious pro users who were g4 desktop bound got tibooks and found they had their needs met quite nicely

Yeah totally....... I was desktop bound for so long....... then I had a company Pismo, and it totally changed the way I worked..... even more so since I bought the TiBook.......

That said I will be buying a tower along with a new PowerBook in Feb....... I'll let the tower take the strain though.........

But I just couldn't live without a PowerBook anymore........ truely an oblect that has changed my life...... :)

Oh to the thread on track...... I'd love a dual TiBook...... it'd totally rock my my world....... :D
 
"The L3 cache more then makes up for any kind of bottleneck between the memory and cpu. ya nit. "

This is not true. Try rendering a million polygon scene in a 3D program and tell me if that is true. With out DDR any data that has to be cached over 100MB will be dramatically slower without DDR. L2&L3 cache is more important in delivering small amounts of data and dealing with speeding up the OS.

Cnet had an article latly about oversized PEECEE Laptops there like 15 pounds.(dont have the link) The last one they talked aboutwas a toshiba. The comapies that sell them claim there desktop replacements.... What they really are is Laptops with a non mobile version of the processor(then use a P-4 not a P-4M)........ And to supply the power to this processor they have a huge amount of ram and because they are grenarlly bigger have a bigger screen.... O yea the new toshiba has a bult in wireless keyboard that snaps out and can go 4 feet away fro mthe computer... I think that DUDE YOUR GETTING A DULL is starting to make some of there clunkers like this(it would probably make them SMALLER).. I guess who ever it was that asked for a BIG laptop... there out there and there pretty reasonanle and powerful for the price... If what u want is a big ugly thing u got it.....

One of my teachers reasonaly got a Dull with the non mobile P-3 in it at like 1.2 GHZ. The Thing has 2 CDROM DRIVES... who the hell would put 2 cdrom drives in a LAPTOP must be a pc thing. its has has a 15 inch screen 256 megs of ram.. weight in at aroung 10 pounds has 2 fans, is about 2 inches think...has 3 hours(barly) of battery life(can only play like 1/2 a dvd)..... he got all this power and bigness for the low low price of 1,500........(it looks like my dads dell he got in 94). Again ur ultra big-n-heavy laptops are outthere.. but i will stick to my 12.1 inch ibook thank you very much(um i would be happy if it was like 10 or 11). its the same size as my textbooks so all i do is put it in its slip and thow it into my bag......i went to circet city today and they dident have one PC laptop that was the size of my ibook with anynear as much battry... the 1 they did have was from SONY..... it had 31/2 hours of battery but NO CDROM DRIVE that required a Dock???yea ok.......oh yes and i really enjoyed playing with the emachines i have never actully seen one that workd:)


Well i am gona go watch a movie with my battery now cuz,,,, since i am useing a SMALL apple i can do that.... .rather than a 15 pound clunker that cant.....

Wow that was one hell of a rant for a newbie ;)
i aggree, big laptops are horriable, i for one will always love the 12.1" ibook 2001-2002.
TC's HUGE LAPTOP also gets hot enough to melt the cheep wood finish on his desk too, you forgot to mention that;)
have fun with your movie.
