If you think Intel’s new processor

naming scheme sounds indecipher-

ably insane, you’re not alone. %ven

Intel admits the model numbers in

this new convention are practically

random. However, the company

did tell us that the factors deter-

mining a CP5’s model number

include architecture, cache, clock

speed, frontside bus, and “other.”

/ther? To us, this is akin to say-

ing the number is based on clock

speed, cache, and the pounds of

butter the average Rhode Islander

consumes. The key concept Intel

wants you to remember is this The

higher the processor number, the

better it is. But how

you define “better”

depends on how

you plan on using

your PC.

To save

you numerous

hassles, we

put together a

handy chart to

decode Intel’s

processor numbers. Keep

these thoughts in mind as you

shop for your new CP5

➤ Generally, Prescott P4s any of

the enhanced .etBurst CP5s   are

better at higher speeds. At low

speeds, like 2.4GHZ

or even 2.80GHZ,

you’re better served

by the old reliable

.orthwood P4 core.

➤ We fear the

Celeron 320 D could

be a serious dog. It

Just doesn’t have the

clock speed.

➤ The Pentium M core

is highly efficient at

most office productiv-

ity apps, and the higher speeds are

generally better. But even at low

clock speeds, the Pentium Ms are

pretty speedy.
