Note: In order to better understand the price consumers are willing to pay for a particular product or service, Dutch
economist Peter van Westendorp developed the Price Sensitivity Meter. The van Westendorp PSM gauges thresholds and
provides a range of acceptable prices. The underlying premise of this model is that there is a relationship between price and
quality and that consumers are willing to pay more for a higher quality product.

10. DTS Clear VoiceTM
• Microphone array processing
• Improve speech perception in noisy environment with following
technologies:
– Noise Suppression | Acoustic Echo Cancellation | Beam Forming
• Focus reception on desired user; suppress feedback from local
loudspeakers; and reject contribution from undesired external
sound sources
• High-performance, low latency, efficient microphone array
processing solution to enrich speech recognition, text-to-speech,
voice info-snacking, voice based activation, etc.
10

11. DTS Clear AudioTM
11
• Environment Noise Compensation
• Intelligently increase the gain at specific frequencies to
counterbalance the undesired signal when noise is detected
• Automatically adjust over when and where is needed (time &
frequency domain)

12. DTS Audio RestorationTM
• Adaptive Dynamic Enhancement
• Intelligently analyze the audio signal for restoration of
compressed or “re-mastered” percussion and transient
sounds
• Brings back the “punch” and “clarity” from dynamic range
compression
12
Peaks of original mix are
squashed after re-mastered
Enhances the dynamic range
and brings back the original
life into the music

13. DTS EnhanceTM
• Low and high frequency enhancement
• Improve natural timbre balance
• Brighten the quality of voice and musical tone
• Bandwidth extension for low-bit rate encoded audio
– MP3, streaming audio, internet TV, etc.

17. It does not have to…
How…
When you close the lid,
your PC turns into a
“BRICK”

18. 18
Closed Lid, Not a Brick…
– Speakers and Microphones are in 100% of Notebooks
– But you can’t use them, even open lid, for many uses
because… Placement, Power, Ease of Use and Fidelity
• These are actually easy to fix… we are already
working to enable several “wow” usages
– Commanding your PC using speaker-independent
Speech Recognition with small vocabulary grammars
– Responding to commands with Text to Speech,
entertainment such as Music Playback and
Communications… all with only the Speakers and
Microphones already there
• Notebooks already have the fundamentals
for usages that work “Closed Lid”

36. Risk Factors
36
The above statements and any others in this document that refer to plans and expectations for the second quarter, the year and the
future are forward-looking statements that involve a number of risks and uncertainties. Many factors could affect Intel’s actual
results, and variances from Intel’s current expectations regarding such factors could cause actual results to differ materially from
those expressed in these forward-looking statements. Intel presently considers the following to be the important factors that could
cause actual results to differ materially from the corporation’s expectations. Demand could be different from Intel's expectations due
to factors including changes in business and economic conditions; customer acceptance of Intel’s and competitors’ products; changes
in customer order patterns including order cancellations; and changes in the level of inventory at customers. Intel operates in
intensely competitive industries that are characterized by a high percentage of costs that are fixed or difficult to reduce in the short
term and product demand that is highly variable and difficult to forecast. Additionally, Intel is in the process of transitioning to its
next generation of products on 32nm process technology, and there could be execution issues associated with these changes,
including product defects and errata along with lower than anticipated manufacturing yields. Revenue and the gross margin
percentage are affected by the timing of new Intel product introductions and the demand for and market acceptance of Intel's
products; actions taken by Intel's competitors, including product offerings and introductions, marketing programs and pricing
pressures and Intel’s response to such actions; defects or disruptions in the supply of materials or resources; and Intel’s ability to
respond quickly to technological developments and to incorporate new features into its products. The gross margin percentage could
vary significantly from expectations based on changes in revenue levels; product mix and pricing; start-up costs, including costs
associated with the new 32nm process technology; variations in inventory valuation, including variations related to the timing of
qualifying products for sale; excess or obsolete inventory; manufacturing yields; changes in unit costs; impairments of long-lived
assets, including manufacturing, assembly/test and intangible assets; the timing and execution of the manufacturing ramp and
associated costs; and capacity utilization. Expenses, particularly certain marketing and compensation expenses, as well as
restructuring and asset impairment charges, vary depending on the level of demand for Intel's products and the level of revenue and
profits. The majority of our non-marketable equity investment portfolio balance is concentrated in the flash memory market segment,
and declines in this market segment or changes in management’s plans with respect to our investment in this market segment could
result in significant impairment charges, impacting restructuring charges as well as gains/losses on equity investments and interest
and other. Intel's results could be impacted by adverse economic, social, political and physical/infrastructure conditions in countries
where Intel, its customers or its suppliers operate, including military conflict and other security risks, natural disasters, infrastructure
disruptions, health concerns and fluctuations in currency exchange rates. Intel’s results could be affected by the timing of closing of
acquisitions and divestitures. Intel's results could be affected by adverse effects associated with product defects and errata
(deviations from published specifications), and by litigation or regulatory matters involving intellectual property, stockholder,
consumer, antitrust and other issues, such as the litigation and regulatory matters described in Intel's SEC reports. An unfavorable
ruling could include monetary damages or an injunction prohibiting us from manufacturing or selling one or more products,
precluding particular business practices, impacting our ability to design our products, or requiring other remedies such as compulsory
licensing of intellectual property. A detailed discussion of these and other factors that could affect Intel’s results is included in Intel’s
SEC filings, including the report on Form 10-Q for the quarter ended March 27, 2010.
