Is T23 faster than T30?

[ulrich.von.lich]

It may be a stupid question but I learned recently from some post here (which I can't find now) that Pentium III 1.3Ghz is faster than Pentium IV 1.8Ghz (which is hotter). Is that true?

And which one is more abuse-proof?

You may confuse this with the Pentium-M Centrino, which is based on the PIII.
A 1.4 Pentium-M is faster, cooler and uses less power than e.g. a 1.8 PIV.
The T23 uses a Pentium III. (Max. 1.2GHz)
The T30 uses a Mobile Pentium 4, (max. 2.4GHz, but the best are the 1.8GHz and 2.0GHz) which is NOT a Pentium-M, but is faster that the PIII.

As long as you don't overclock them (you can't anyway) both CPU types can handle all the stress you care to give them.

Related observation but not an answer:

I procured an HP laptop with a PIV 2.3mhz. And I'm like you, it doesn't seem much, (if any) faster than my T23, both with 512 of mem. Maybe IBM did a better job of building theirs....

There is a little more to it than just CPU speed and Memory size. Computer performance also depends on how well the various components work together on the motherboard. That usually requires more R&D and using parts that are designed to run properly, not designed strictly to sell for the lowest possible price.

I knew there was a reason I liked TP's so much..

In the mobile PC & mobile mini PC business, marketing departments have a big say in the shape of the final product.

Marketing departments do not want brilliant
products. They want lots of large numbers to play with. By the time marketing is done with computer design departments, they have a set of numbers to fly around at the average consumer. Automobile Dealers have their number juggling side show salesmen. Their favorite are trade-ins which offer more numbers to juggle. The mobile computer industry has their marketing departments magicians who specialize in number mumbo jumbo.

A standard practice in the mobile computer business, thanks to marketing trick-o-nologists,
is the clock speed juggling act. Unknown to
most buyers is that no mobile PC ships that is not significantly under clocked. An exception was the unique Casio BE-300 & earlier Thinkpads run closer to speed that most others. They also retailed at a high price, just like their main competitor for top spot, Compaq.

More typical is the new Asus Eee PC ultra-Mobile PC. It sports, marketing loudly
proclaims, a 900MHz Intel Celeron series
M processor. What buyers are not told is
that it is intentionally clocked down to
630MHz to reduce heat output and battery
depletion. That way a noisy but not very
effective cheap fan can be employed, instead
of a real heat solution.

Marketing wants at least average industry
battery charge times to boast about and the
least expensive processors with the fastest
possible POTENTIAL speed.

Marketing wants a collection of Laptop component specs with which to peddle their wares but these specs often
clash, so the simple thing to do is cut cost
corners and reduce actual performance figures of components buyers ovrelook, such as a 160gig HDD in an Intel Dual Core laptop that retails for only $500. How many buyers know to check the RPM of the HDD or its failure rate? By the way, how many laptop users need 80gigs, less much 160?

A rule of thumb for buying a laptop is to know
what numbers you need that the maker does
not advertise. One is HDD RPM. Just try to find out from a chain store official tech savy salesman. Another item is the make of the double layer CD\DVD burner-multiplayer. What is the PC's side bus speed? The motherboard throughput speed? After under clocking, what is the processor's true end speed?

I am constantly comparing my IBM T23 productivity speed with $500 chain store
laptops that are advertised with a list of very impressive specs - Gateway, Acer, HP, Compaq, even some Toshiba models. So far, my old T23
outperforms them. I do cheat. I have a dual boot, Windows 2000 and Ubuntu Linux setup, not Vista Home.
