Ti - Laptop Magazine
The Ti is one of the newest breeds of Centrino system, boasting
a faster and more efficient Dothan core Pentium M - a 2GHz
ship. While the original Banias processor had 1MB of L2 cache
and topped out at 1.7GHz, Dothan doubles this and increases the
clockspeed to 1.8GHz and beyond. Because the new strained silicon
used in this machine has been made using a 90 nanometre someone
process, using Intel has been able to reduce transistor size,
thereby increasing the number of transistors (from 77 million
to 140 million) for greater performance. Yes, the 1.7GHz Banias
core chips were good, but Dothan is potentially even better.
Teamed with 1GB of RAM and a 60GB 7200rpm hard disk, the TI notches
up a sky-high score of 212 in its MobileMark test, while its six-cell
lithium-ion battery lasts for a solid 172 minutes. Admittedly,
the battery life is less than the 3 to 4 hours we’re used
to from the older Banias core Centrino systems, but turning the
battery-saving features on will doubtless extend the longevity.
new processor isn’t the be-all and end-all of the system,
and although it’s not the biggest chassis, a DVD/RW drive,
three USB 2.0 ports, one FireWire jack and a lone PCMCIA interface
are incorporated. The 15.4-inch screen is a good compromise between
a bog-standard 15-inch and a bulky, power sucking 17-inch panel.
Other notable features include a dual-mode 802.11b/g module to
take advantage of faster wireless speeds, and a 3-in-1 card reader
hosted on the front panel.
terms of graphical whiz, the ATi Mobility Radeon 9700 records
a score of 10,470 in the 3Dmark 2001SE test. We also test visual
performance with 3Dmark 2003, and here the Pegasus Ti scored an
equally lofty 2,930, meaning it will make light work of everything
from Excel to Everquest.
Dothan or not to Dothan? That is the question. For now, the first
Dothan chips are nothing to get too excited about. They’re
‘evolutionary’ rather than’revolutionary’
and we won’t see a big impact on laptop design until Dothan
is incorporated alongside Intel’s Alviso chipset in the
‘Centrino 2’ Sonoma platform. Nevertheless, this 2GHz
machine forms an impressive overall package - good looking,
best all round chip just got better. The older Banias chip
just got cheaper.
