My 2.0Ghz / 755 T42p is in my hands!!

[LinuxGuy75]

Finally, after a long wait, my 2373-KUU is here.

No dead pixels, the 9cell battery fits snuggly.

I'm installing a 512MB SODIMM I bought from Crucial to bring the memory up to 1GB.

I'm VERY pleased.

The only annoying thing is gunk left behind after peeling off the stupid "designed for WindowsXP".

I went and stuck the sticker on the urinal in the bathroom.

How much did you pay for the lappy?

Is it FAST???

Congratulations on you purchase
and to get off the gunk a little alcohol or very little WD40 sprayed on a cloth light rubbing anf your set also use the alcohol to get the WD40 residue off if you use it.

[fox_napier]

How much of a real world difference is there between the 745 (1.8Ghz) and the 755 (2.0Ghz) in terms of performance? Where will you 1) most certainly notice the difference and 2) where will you not?

Also, if you have 1GB+ of memory will this performance difference be reduced?

When is the next speed step of Intel's mobile CPUs going to be released and what speed will it be?

I haven't much time to use it yet, but it seems very snappy.

I paid $3,152.65 plus $208 tax. That was 15% off. When I called IBM sales on the phone, they gave me that price with virtually no hassle.

When is the next speed step of Intel's mobile CPUs going to be released and what speed will it be?

The current plan is to release Alviso and Sonoma, a chip and a chipset in Q4 of this year. The top clock speed of Dothan is going to be 2.13GHz, but remember that the increase to a 533MHz FSB is going to give this chip another performance boost. We might see this chip rival several high end desktops! Sounds fun.

The 2.0 GHz Dothan handily beats the 3.40 GHz Prescott Pentium 4 in SPECint, though it looses in SPECfp.

Supposedly an increase in the Dothan's FSB would help fp performance.

Is it FAST???

[Chatbox]

Wow, that sounds really fast.

Makes me want to return my T41p.

[K. Eng]

Computational benchmark #'s can be seductive, but most people will never notice the difference. My 1.30 GHz PM is bottom of the barrel, but it's plenty fast for everything I do.

Now if that extra clockspeed would save you a couple hours a day in waiting time for results in a specific task, that might be reason to cry

[Guest]

Okay I understand or accept that the new Dothan models are not that much better than the non Dothan models. By better I mean average user (non gamer) won't notice it. But what does the new 533MHz FSB mean for computers? I am not a computer genius at all. But I thought I knew a decent amount. Ram tells how much the computer can do and processor speed tells how fast. What is the new FSB it supposed to do? Don’t most desktops come with 800mhz FSB? Isn't the new alviso and Sonoma supposed to be a bigger deal/improvement than Dothan? For me it sounds like it. Teach me?

[K. Eng]

The Front Side Bus connects the Processor to the MCH (basically the memory controller + some other stuff) of the 855 chipset. In order to access main memory, the CPU must send requests over the FSB and receive data & instructions over the FSB. A faster FSB means that the Processor can theoretically have faster access to memory.

You can learn a lot about chipsets and FSB from the following article:
http://www.anandtech.com/chipsets/showdoc.html?i=2088
The Alviso chipset will incorporate many of the technologies discussed in the Anandtech article.

Hmm... this thread has gotten derailed. A technical forum might be nice.

Some P4 info on FSB increase:

[geekman686]

The problem with the computer industry for consumers is that there is always something better, something faster coming down the pipeline in a couple of months... If you take the mindset that I want something a few months from now, you will always be waiting for the NEXT MAJOR ADVANCEMENT.

If you need a computer just suck it up and buy it now... knowing that in a few months something faster, cheaper and better will be out soon.

My one year old T40 is considered ancient now.. but it does everything I need.

[Guest]

That is true there is something always new but how significant is it. I find that the new FSB seems better than Dothan. Considering this what was the last big thing in the T series or laptops in general?

[GoldenKing]

Congratulations

Probably the release of the T20 itself Roughly speaking:

T20 - first T series obviously. Mobile Pentium III based. (13.3"/14.1" XGA)

T21 - Improvements: faster (800 and 850MHz models) and some models with Savage IX8+ and SXGA+ vs. the T20 and XGA T21s on SavageIX8.

T22 - Again faster speeds, 900 and 1GHz Mobile Pentium III. All models now with SavageIX8+, again some with XGA, some with SXGA+.

T23 - Bigger changes. 133MHz FSB vs. the 100MHz FSB on the T20/21/22. i830MP chipset vs. the venerable i440BX system in the earlier T2xs. 2 x USB 1.1 vs. 1 x USB 1.1. Pentium III-m Tualatin processors, with faster speeds of (866, 1.0GHz), 1.13GHz and 1.2GHz. 16MB SuperSavage/IXc Graphics Chipset - AGP 4x based vs. AGP 2x in T20/21 and 22.. Maxiumum of 1024MB memory supported vs. older 512meg limit of 440BX systems (the T20/21/22 etc.) 802.11b wireless built into some models.

(The T23 does make some pretty big changes)

T30 - 266MHz FSB (PC2100) this time around. i845MP chipset vs. i830MP in T23. Pentium 4m Processors from 1.6GHz to 2.4GHz (and 2.6GHz from user upgraded). 16meg ATI Radeon 7500 AGP4x. Still 1GB memory maximum. Bluetooth is now an option in the T30 and onwards.

T40 - 266MHz FSB like T30. i855 chipset. Pentium-m Banias 1.3-1.6GHz from IBM. ATi Mobility Radeon (16mb)/Mobility Radeon 7500 (32mb)/Mobility Radeon 9000 (32mb) or Mobility FireGL 9000 (64mb). USB 2.0 instead of 1.1. NO SERIAL PORT ANY MORE. 1Gb ethernet now an option vs. the 10/100 of T20-T30. 2GB maximum memory. Think thats it!

T41 - PC2700 (333MHz) FSB now. Pentium-m Banias 1.4Ghz-1.7GHz from IBM. Same graphics options except T41p is now Fire GL T2 (instead of 9000) at 128MB. (vs. 64MB). Edit: forgot the active protection system thingy for the hard disk, the motion dectector that parks the drive's heads if a rapid fall is detected.

T41 - PC2700 still. Dothan based (735/745/755 present CPU options). ATI Radeon 7500 still an option, but now also a 64meg ATI Radeon 9600 graphics option enters the foray. You can now get the T42 in 14.1" form factor or 15." form factor. Resolutions available are XGA, SXGA+ and UXGA Flexview on the 15" panel.

....


Also, T23, 30, 40(p), 41(p) and 42(p) are compatible with so called 'ThinkVantage' technologies...


whew

How to read that well - for example the T23 says some models have wireless built in, therefore this propogates down to the next entity, the T30, the T40 and so on unless something for T41 says "No more wireless but free dime bar and armadillo with every purchase", then you will get a dime bar and a wicked animal instead of wireless. Flippancy was my middle name

Still I think that pretty much says it all.

My own POV is that while the T20 was the beginning of it all, it must have been the successor to the 600X (esp. the CuMine based 650MHz ones rather than the 450/500MHz Katmai based 600Xs); therefore not much changed, different CPU form factor, 14.1" screen option and better graphics chip but otherwise they remained distinctly similar. But still the T20 was an 'evolutionary leap'.

Then I would say the T23. (Well I would - it was odd because it packed in a lot of things that did make a difference) Then after that I will say T40 because the form factor was significantly changed and some argue improved, and more modern options were coming through like the i855 chipset, Pentium-m, USB 2.0, Bluetooth/Wireless/1Gb Ethernet capable in some models etc.

I hope this helps Hopefully this will enable you to decide from the changes listed above which T series machine(s) have marked a big change in the series.

I think I'll make my breakfast!

Thank you for that thorough reply. So basically the breakthrough models/specs were the T23 and the T40. Not too bad it does not sound hardware wise like they are too different? So I guess really there really isn't anything Big around the corners alot. For example the Pentium M processors are what I would consider to be big. The Dothan not too much correct? New FSb is big enough. As for computers in general I have not really been reading on anything new except of course the 64 bit processor which is still not that serious because many programs are not made 64 bit yet. Also something about a pci express card. That is for gamers right? Also I guess what I would consider to be breakthrough is some that can't be bough in the stores and online or too hard for the average person to stick in. One exception would be wireless. It is nice having the wireless card integrated but it can/could still be bough in the store right? Processors, chips all pretty big? Bluetooth can be bought? What else.....

[AtmosMan]

Yeah. The 64 bit thing is going to be a big change. Another thing is Intel and dual core chips (two processors on one die.) Once Alviso and Sonoma come out, and Dothans are used up to their potential, then the next big thing coming is probably going to be the dual core and/or 64 bit processor. So I think within the next year or so, you will see the best performance single core, 32 bit computing can offer...then a new realm of personal computing comes our way!

[Guest]

That being said I really hoping that my Toshiba does not give me any problems the first few weeks of September when I get back to college. I hope that the alviso and Sonoma ________ (what are they exactly) will be out and in a T42. The whole package will be called centrino 2 right? I am however not waiting/relying on it. If my Toshiba begins to act up or gets a virus as soon as I get back. I will buy one of the T42s out now. Everyday in school without a computer is dangerous especially the first days when I have to be constantly online making sure my classes are set, add/drop, and emailing teachers.

[lilserenity]

I have to admit that I don't find myself getting all excited about 64bit chips as I do about dual core processors on one die, now that to me is cool. The bit-tage thing ie: 64bits vs. 32bits reminds me of the days of all this 8 bit vs. 16bit vs. 32bit many moons ago; where much like processor speed these days, non PC-compatibles used to use this as a feature.

At the end of the day I suppose the reason is, is because 32bit processors are already handling 64bit calculations (otherwise we would have nasty 4.3gb limits on FAT32/NTFS filing systems etc.), this has always been the case like with the 68000 (Motorola) back 'in the day' where they did not have a 32bit address bus, or a 32bit data bus, but loading two consecutive data registers (d0, d2, d4 ... d14 )say in to d0,d1 with a MOVE.l d0,<large number> would allow this processor that while not externally 32bit, it could work on 32bit arithmetic internally - the only problem was that it took two instructions instead of one to load the address (ie: two 16bit words to make the 32bit number) - and the same thing happens now to do 64bit arithmetic.

For this reason, I fail to get worked up about the increased 'bandwidth' in a processor; back when the 68000 was a beast running at 7.14MHz (on the Atari ST 8MHz, much was made of the .76MHz in the Amiga 1000 Vs. 512ST in 1985...); one could appreciate in the longer term that doing a lot of 32bit work would essentially halve the processor's speed. (Of course the 68020+ was 32bit data bus enabled) But these days when we are into GHz speeds - the average user isn't going to be crippled by this.

Sure disk access will indeed speed up; that will be nice (ie: doing 64bit addressing natively), and we will be able to have more than 4GB RAM in single CPU systems, that too is also nice. But I really do wonder whether the average user is going to notice these things, and the day MS Office or something of that ilk says on the box "2.0GHz Pentium 4, 3.5GB RAM and 90GB of hard disk space minimum requirements" - thats when I will begin to think programmers have really gone to pot....

But I'm not what you could call all worked up about it all, bar the dual core on one die processors, now that would be cool.

*pats her T23* For now a 1.13GHz PIII and 1GB of RAM on a 133MHz bus is more than fast enough. (in fact most people are stunned how fast and usable the T23 is, for a computer, not a laptop )
