First PowerPC 7448 CPU Upgrade for Mac Ships!

Daystar announces shipment of the first XLR8 brand, Apple PowerBook 7448
Upgrade at 1.83 GHz… using Freescale’s newest 7448 PowerPC CPUs!

Atlanta, Georgia, March 5, 2006: Daystar Technology, the original Mac
Performance Shop, delivered another new milestone in both CPU upgrades and
PowerBook speed today. The company announced a new 7448 based CPU upgrade
for the PowerBook G4 1.67. The “XLR8 MAChSpeed 7448 Aluminum” is a factory
installed upgrade, and will be widely available within the next month.

The first “customer” upgrade has shipped to Mr. Lasse Kvernmo, as a
“pre-release” edition of the forthcoming product. Mr. Kvermmo is using his
new 1.83 GHz 7448 PowerBook as an audio/video workhorse within the
entertainment industry.

Newest PowerBook Only (1.67 GHz).

The 7448 upgrade is limited to the PowerBook 1.67 GHz series only. This
limitation is due to hardware restrictions within the PowerBook, which
prevent the use of the 7448 in earlier systems. The upgrade also requires
Mac OS X 10.4.4 or later.

Like the XLR8 MAChSpeed G4 Aluminum, the PowerBook 7448 upgrade is a
factory installed CPU upgrade. Users simply place their PowerBook in the
provided box. The shipping, testing, installation and 100% quality
assurance is handled completely by Daystar’s Apple Certified Technicians.

No Compromise, Just Raw Speed.

The 1MB L2 size is optimal for maximum performance with the best balance
between performance and overhead.

In real-world (Photoshop) benchmarks, the 7448 performs 20-30% faster than
a 7447A at the same MHz. Overall the XLR8 MAChSpeed 7448 Aluminum provides
30-60% more performance for PowerBook users.

“Since we began shipping the MAChSpeed G4 Aluminum (7447) a couple weeks
ago, we have been swamped with requests to upgrade the PowerBook 1.67’s. “,
said Gary Dailey, president of Daystar. “I finally decided to just go ahead
and open the doors on the 7448. Now users won’t wonder why we didn’t
provide a 7447A option for the PowerBook 1.67”.
