Go over the Do Now
Assignment #1: So we have seen the features of the Pentium III. Now let’s move on to the next generation
of Intel processors, namely the Pentium 4. Go to www.techweb.com/encyclopedia. Look up Pentium 4.
Focus on and answer the following questions.
1) What FSB speed did the Pentium 4 start out with?
100MHz quad pumped for a total of 400 MHz
2) The first Pentium 4 supported only what type of RAM?
RDRAM
3) What type of RAM did the Pentium 4 subsequently support?
SDRAM
4) How many pins were on the first Pentium 4 PGA package?
423
5) How many pins and what type of package did subsequent Pentium 4 chips have?
478
Assignment #2: In certain Pentium 4 CPU’s there was a technology that increased performance by 30%. To
find out about this technology, look up Hyper-Threading at www.techweb.com/encyclopedia. What is
Hyper-Threading?
A feature of certain Pentium 4 chips that makes one physical CPU appear as two logical CPUs. It uses additional
registers to overlap two instruction streams in order to achieve an approximate 30% gain in performance.
Multithreaded applications take advantage of the Hyper-Threaded hardware as they would on any dual-processor
system; however, the performance gain cannot equal that of true dual-processor CPUs.
Assignment #3: When Intel introduced its Pentium 4, AMD released an upgraded version of the Athlon
Thunderbird. To find out more about this new AMD CPU, go to www.techweb.com/encyclopedia and look
up Athlon XP and answer the following questions:
1) When was the Athlon XP introduced?
2001
2) Instead of a Megahertz designation, how did AMD designate these CPUs?
Performance Rating
Assignment #4: Just as the Celeron describes a series of lower-end processors built around the Pentium II,
Pentium III, and Pentium 4, there was another series of high-end processors built around the Pentium II,
Pentium III, and Pentium 4. To find out about this series of high-end processors, look up Xeon at
www.techweb.com/encyclopedia and at www.pcwebopedia.com and answer the following questions:
1) What kind of computers were the Xeon processors designed to be used in?
Servers
3) What type of slot did Pentium II and Pentium III Xeon chips connect to?
Slot 2
Some other notes on the Xeon processors:
A) Xeon processors add massive amounts of L2 caches
B) Xeon processors were designed to work in multiprocessor systems, like high end servers. For example
take a look at this URL: http://www.tigerdirect.com/applications/SearchTools/itemdetails.asp?EdpNo=5353322&CatId=2683. What type and how many processors does this server support?
2
3) The Pentium 4 Xeon came in two varieties; Pentium 4 Xeon and Pentium 4 Xeon MP. Although the
Pentium 4 supports multiple processors, the Pentium 4 Xeon is specifically designed to handle many
processors. Also, the Pentium 4 Xeon went back to the PGA style package instead of the SEC package that
the Pentium II Xeon and Pentium III Xeon used (to connect to slot 2).
The time has come for the address bus size to increase from 32 bits, which allowed for 4GB of RAM to be
addressed, theoretically. The new address bus sized that has come out is 64 bits allowing for a theoretical
maximum amount of RAM
of GB of RAM
2^64 bytes
Assignment #5: Research the following 64-bit address bus processors and write short summaries on each.
A) Itanium The CPU family from Intel that is based on its next-generation, 64-bit IA-64 architecture. The operating
systems that are available for Itanium computers are Windows Server 2003, HP-UX and Linux.
Itaniums run IA-64 applications in the CPU's native mode, and they run IA-32 (x86) and HP PA-RISC
applications in an emulation mode. IA-32 programs are executed directly in the Itanium's hardware
layer or via a software layer in the operating system (see IA-32 Execution Layer). HP PA-RISC
applications are run via a software translator (see Aries).
Following are the various Itanium models that have been released along with their code names (in
parentheses) as well as models expected in the future. See IA-64 for more on the Itanium architecture.
First Itanium (Merced)
The first Itanium chips were introduced in 2001 with a clock speed of 733 MHz and a 180 nanometer
process technology. L3 cache sizes were up to 4MB.
Itanium 2 (McKinley, Madison, Deerfield, Fanwood)
Starting in 2002, the Itanium 2 line was released with clock speeds starting at 900 MHz and increasing
to 1.7 GHz. Memory bandwidth was increased from the first Itanium's 2.1 Gbps to 6.4 Gbps. Starting
with the Madison chips in 2003, the process technology was reduced to 130 nanometers. L3 cache sizes
reached 9MB.
Dual Core Itanium 2 (Montecito, Millington)
In 2006, the third generation Itanium models were introduced with dual cores, up to 24MB L3 cache
and 1.7 billion transistors.
Itanium 3? (Tukwila, Poulson, Kittson)
Quad-core Itaniums, code named Tukwila, are expected in 2009 with a process technology of 65 nm.
Poulson and Kittson are future chips with more cores.
B) Opteron –
A family of 64-bit CPU chips from AMD, formerly code named Sledgehammer (part of the Hammer
line). Introduced in April 2003, the Opteron fully supports 32-bit applications, but requires that
programs be optimized and recompiled to take full advantage of the 64 bits. The 64-bit version of
Windows XP also takes advantage of the increased CPU word size. Intended for servers and high-end
workstations, the Opteron competes with Intel's Xeon and Itanium lines. AMD subsequently introduced
64-bit Athlon CPUs (see Athlon).
Multicore Opterons
In 2005, following the introduction of its Athlon dual-core chips, AMD introduced dual-core Opterons
with quad-core compatibility (dual cores could be replaced with quad-core chips on the same
motherboard). In 2007, it introduced the Quad-Core AMD Opteron processor (code named Barcelona).
