X nm – officially used to describe “half pitch”,
concentration of transistors on a processor.
Transistors are 1/2 X nm apart
2 classical measures of CPU performance are IPC
(instructions per cycle) and clock speed
“Megahertz myth” – one processor takes two
clock cycles to add two numbers and another
clock cycle to multiply by a third number,
whereas another processor may do the same
calculation in two clock cycle

Pentium 4
Willamette– 180nm, Nov 2000
L2-Cache: 256KB
Integrated heat disperser
Tom Yager of Infoworld magazine called it "the
fastest CPU - for programs that fit entirely in
cache"

hpkDNpQ
 Focused
on clock speeds
 Inefficiently designed
AMD Athlon
 Palomino –
180nm, October
2001
 Marketed using
“performance
rating” system
 L2-Cache: 256kB
Pentium 4
• Northwood – 130nm,
Jan 2002
• L2-Cache: 512 KB
• achieved clock
speeds 70% higher
than Willamette
AMD Athlon
 Thoroughbred –
130nm, June 2002
 L2-Cache: 256kB
 AMD's first
production 130 nm
silicon, significant
reduction in die
size compared to
its 180 nm
predecessor.
Pentium 4
• Northwood – 130nm,
Nov 2002
• L2-Cache: 512 KB
• Introduced
hyperthreading
technology
AMD Athlon 64
 SledgeHammer –
130nm, September
2003
 L2-Cache: 1024 KB
 64bit architecture,
supported more
RAM than 32 bit,
allowing programs
to store larger
amounts of data in
memory
Pentium 4
• Gallatin (Extreme
Edition) – 130nm,
Sept 2003
• Differed from
Northwood by an
added 2 MB of level
3 cache
AMD Athlon
 SledgeHammer –
130nm, September
2003
 L2-Cache: 1024 KB
 64bit architecture,
supported more
RAM than 32 bit,
allowing programs
to store larger
amounts of data in

Pentium 4
Prescott – 90nm, Feb
2004
L2-cache – 1024kB
Achieved clock
speeds 12% higher
than Northwood
“a major reworking
of the Pentium 4's
microarchitecture”
 An
age of AMD leading innovation and
establishing market dominance
 AMD was no longer the “poor man’s
chip”
 Intel forced to rework chip architecture
 UsRobotics
introduces the V.92 modem
standard February 27, 2001.
 SATA 1.0 is introduced in August 2001.
 USB 2.0 is introduced.
 DDR2 SDRAM begins being sold.
 Microsoft
announces on January 1, 2001
Windows 95 is now a legacy item and will
no longer be sold or shipped to any more
customers.
 Apple introduces Mac OS X 10.0 code
named Cheetah and becomes available
March 24, 2001.
 Microsoft Windows XP home and
professional editions are released
October 25, 2001.
 The
first of code that would later become
Mozilla Firefox is made available
September 23, 2002.
 Apple opens the iTunes store April 28,
2003.
 The game Second Life is released June
23, 2003.
 The Internet VoIP service Skype goes
public August 29, 2003.
 MySpace
official site is launched January
2004.
 Mark Zuckerberg launches Thefacebook
February 4, 2004, which later becomes
Facebook.
 Google announces Gmail on April 1,
2004. Many people take it as an April
Fools joke.
 The
first release of Ubuntu is released
October 20, 2004.
 Blizzard's World of Warcraft game is
released November 23, 2004.
 In
2001, Approximately 1 billion PCs have
been shipped worldwide since the mid'70s
 The PC has slowly become a staple in the
life of the American public and the world
 Wide use of personal computers makes
exploiting vulnerabilities a worthwhile
enterprise for blackhats
 Code
Red – July 2001
 Repeated the letter N, exploiting the
overflow buffer, then line of executable
code
 Days 1-19 infest, Days 20-27 DoS
 Nearly 360,000 infected hosts
 HELLO! Welcome to http://www.worm.com!
Hacked By Chinese!
 https://www.youtube.com/watch?v=iu48QBJ
P_p0
 Slammer
worm – January 2003
 The sole purpose of the code was to
replicate
 Extremely simplistic, 400 bytes in size
 Again, exploited buffer overflow
 Mydoom
virus – January 2004
 Sent out by email with an executable
attatchment
 If executed, the virus would send itself to
everyone in the host computer’s address
book, opened port 3127
 DoS attack against SCO group
 2001-2004
was a time of great
advancement in hardware technologies
 Businesses trying to capitalize on public
interest resulted in new software and
websites
 Masses flocking to computing resulted in
an influx of exploitive viruses
