Introduction

The Company
The company is based in Santa Clara, California, U.S. Founded by Gordon E. Moore and
Robert Noyce in 1968. Before Intel came to be, it was named NM Electronics. In a year, the
founders decided to name the company Integrated Electronics instead, Intel for short. 2010
report shows Intel has 82,500 employees while its rival company only 11,100.

The Technology
Being Intel’s flagship for more than a year in the current market, the product has shown
interesting traits and uses very advanced technology to be in the spotlight for so long. If Intel
had not released the Core i7 990X in Q2 2011, the 980X could have still been first in the
market. The Core i7 980X is the first true six-core processor released for end-users with
hyperthreading support giving processing power of 12 threads, providing server-grade
performance. The Core i7 980X is built based on the 32nm manufacturing process. Therefore,
the Core i7 980X processor shall be the focus of this study.

Process and Design of Core i7 980X

Input and output
Core i7 980x is inserted into the motherboard with LGA-1366 socket and X58 chipset. Gulftown
sticks to Ronak’s 2MB of L3 per core rule and has a full, 12MB shared L3 cache that’s
accessible by any or all of the six cores. It’s actually because of the large unified L3 cache
that performance in applications that don’t use all six cores can be higher than quad-core
Core i7s. Gulftown has a 48 cycle 12MB L3, a 14% higher latency for a 50% increase in size.

Stage by stage explanation
(Shenton College, 2009)

   1. Fetch
          a. The CPU communicates this address over the address bus to main memory,
              with signals indicating it needs the instruction stored at that address (This
              activates the Memory location) (1 clock cycle)The Core i7 980X utlises the
              new QPI I/O bus to quickly fetch data
          b. Main memory then transmits the instruction along the data bus to the CPU
              (The Control Unit sends a READ signal) (another clock cycle)
          c. The new QPI feature in the Core i7 980X allows faster communication
              between buses
   2. Decode
          a. Once an instruction has been fetched, it must be decoded
          b. With hyperthreading, the Core i7 980x can decode faster without
              compromising performance
   3. Execute
          a. After the instruction have been decoded/fetched, it can be executed(carry out)
              by the ALU
          b. These instructions are carried out at an electronics level
          c. Core i7 980x can execute faster because of IMC.

The Fetch, Decode & Execute Cycle
         (Kristin, 2011)
                                                                                  P a g e | 10


Physical design
It is a small chip which is square in shape with integrated heat sink (IHS). The IHS is mainly
made out of copper to better transfer heat to the heat sink for heat dissipation. The
semiconductor works best with lower temeperatures.

Types of Design

Universal Design
Core i7 980x fits into motherboard socket LGA-1366 with the Tylersburg chipset. These
motherboards feature the support of 3 to 4 16x PCIe 2.1 lanes and tri-channel memory for
maximal performance and extension.

Functional design
The Core i7 980X is the first LGA-1366 processor based on Intel’s Westmere architecture.
The size of the die is smaller which is due to its 32nm manufacturing process. The design
does not only save cost but also produce less due to less energy loss, which is also an effect
of 32nm manufacturing process. It has 6 cores in a single die with an integrated memory
controller(IMC) featuring QPI links(Quick Patch Interconnect) and shared L3 cache(Level 3).

Life Cycle of Core i7 980X

Current stage
Core i7 980X is in decline stage because of the released of core i7 990X. Core i7 990X will
replace core i7 980X soon in terms of the price and performance. Intel claimed that core i7
990X is crazy fast just got faster.

Previous stage
Core i7 980X is in maturity stage for the past year being Intel’s flagship and have been the
top of the end-user market as well, costing $999 constantly without any drop or raise.
                                                                                P a g e | 13


Alternatives of Core i7 980X

Other Intel products
One can easily obtain another cheaper processor from Intel Core i7 series, the 920, 930 and
950. However, these mentioned processors offer only 4 true cores as compared the 980X’s 6
true core. The processing power has a big significant performance gap as well as price. Not
only that, the models mentioned above uses 45nm manufacturing process, which can relate to
higher power consumption and higher core temperature. However, all the products mentioned
do have Intel Turbo Boost technology. This feature ramp up the processor with slightly
higher core voltage and increases the core speed with x1 to x2 multiplier for higher
performance.

AMD
If one does not favour Intel, perhaps AMD is the choice. AMD offers six-core processors at a
low price, $199. Usually, really budget users will head for AMD while performance users
look for Intel. This is proven with numerous reviews made in the Internet, depicting
performance of processors from the Blue and Red camp. The flagship of AMD at that
moment was AMD Phenom II X6 1090T. It is very cheap but, performance wise, nowhere
near Intel Core i7. As depicted below, the performance of AMD Phenom II X6 1090T
overclocked to 4.1ghz barely scratched Intel Core i7 980X at stock clocks.

External factors influencing Core i7 980X

Social
Most of the people need computer to complete their task nowadays. People prefer the latest
technology because it can be more productive, thus the demands of the better processor
increased. Most performance seeker purchased the Core i7 980X for optimal single-processor
performance. However, there are people too who bought the technology just for the bragging
rights.

Political
There are no political influences which affects the Core i7 980X technology.

Business and Economical
Economical breakdown in 2009 and 2010 cause slower technological advancement thus
delayed the release of Core i7 980X as compared to the initial release of Core i7 products,
Core i7 920.

Intel is smart with releasing its new flagship. Since years ago, Intel always sold its flagship at
the same price, the successor replacing the predecessor, both in price and performance. The
price tag is a hefty $999. This causes the high-end users to be forced to get a new line of
product every time its released, better performance with the same price tag. This idea is better
sold than better performance with slightly higher price tag.
                                                                                    P a g e | 20


Ethics and Core i7 980X

Warranty
The Core i7 980X processor comes with a 3 year limited warranty. This type of warranty
usually do not cover end-user faults but if there are any manufacturer side faults, the end-user
can return the goods to the supplier to be repaired or replaced. This transaction is called
Return Merchandise Authorisation, more commonly known as RMA.

Recall
If the manufacture line ever messes up the processors with errata or faults which cause too
much problem for the processor to function normally, Intel is bound to make a recall of
products from all the suppliers providing free repair/replacement for all the products that
were sold to end-users.
                                                                                    P a g e | 21


Future of Core i7 980X

Core i7 990X
Needless to say, Intel’s most recent release, the Core i7 990X, is a future of Core i7 980X for
a short-term. The original 980X was based on the Nehalem architecture, called Westmere.
After a year of being released, Intel finally released the 2nd generation Core product line, the
Sandy Bridge processors. These processors are part of the “tick-tock” strategy of Intel.

LGA 2011
The LGA 2011 is an Intel’s yet-to-be released socket. This socket is set to supersede Intel’s
LGA1356 and LGA1366 in the high-end desktop market. This socket has 2011 contact points
with pins protruding. This socket is rumoured to have QPI and quad-channel memory support.
Not only that, it is also rumoured to support 32x PCIe 3.0 lanes instead of 16x PCIe 2.1 lanes
of most LGA1366 boards. The chipset which supports the motherboard is codenamed ‘Ivy
Bridge’, whereas the latest LGA1155 is codenamed ‘Sandy Bridge’ which had several South
Bridge (ICH) faults which caused data lost. Intel authorised a recall on all defective
motherboard and gave free replacement with the B3 stepping.
