New Intel Centrino Core Duo Mobile Technology
Intel's new Centrino Core Duo has revolutionized the mobile experience. The introduction of Dual Core Technology to the mobile theater will let the personal and professional user do more then ever before with their notebooks. With the combination of the new Intel Mobile 945 Express Chipset and the Intel Pro/Wireless 3945ABG Network connection the mobile experience will be unparalleled.

Key Components to be Centrino Duo Certified Notebook

  • Intel Core Duo Processor

  • Intel Mobile 945 Express Chipset

  • Intel Pro/Wireless 3945ABG Network Connection

 

** You will also need a compatible notebook shell to install these parts. ASI Currently has the new ASUS Z62F model which has two ASI SKU # 44637 (CDRW drive) & # 45734 (DVDRW drive). More details coming soon to www.asimobile.com **

 

 

What is "NAPA"?

Now the combination of the Core Duo processor, 945 Express chipset and the 3945ABG wireless solution is what is known as the "Napa" platform.  In other words, the code name for Centrino Duo is Napa.  Its predecessor is "Sonoma" which is the code name for the Centrino platform that was composed of Intel’s Pentium M (based on Dothan), 915 chipset and 2915ABG wireless solution. 

Increased Speeds

Napa increases the FSB from 533MHz to 667MHz and increases the memory from DDR2 533MHz to DDR2 667MHz. With DDR2 667MHz there will be better performance for the integrated graphics and lower latency memory access to run synchronous with the 667MHz FSB.

The Benefits of Dual Core Mobile Technology

  • Revolutionary Mobile Performance

  • Increased Memory & Front Side Bus speeds to DDR2 667MHz (still backward compatible 533)

  • Lower Power consumption for better battery life

  • Expanded wireless connectivity

  • Smaller hardware form factor

A look at both processors

 Dothan and Yonah are NOT pin-compatible.
  Dothan         Core Duo "Yonah"                   "Dothan"                    Core Duo "Yonah"
-
The Yonah technology is based on the 65 nm fabrication process. and when compared to the Dothan CPUs the die shrink allow Intel to place more transistors into the same surface area. Which also helps to reduce some of the production costs.

Both of Yonah's cores only populate a surface area of 90.3 mm2, that includes a 2 MB L2 cache, with the transistor count of 151 million. This die is slightly larger than the Dothan Processor  with a single core which includes roughly 140 million transistors on a surface area of 83.6 m2

Core Duo Key Features
  • Smart Cache
  • Dynamic Power Coordination
  • Digital Media Boost
Smart Cache
  • One of the benefits of the smart cache is that both cores have full access of the 2MB L2 cache and can dynamically allocate the cache for the best and fastest access.
  • The Core Duo Processor also shares data between the two cores for the most efficiency possible.
  • This CPU also is equipped with Enhanced Data Pre-Fetch Logic to enhance the access to the L2 cache.
Dynamic Power Coordination The Intel Core Duo processor delivers dual-core coordinated performance on demand, with enhanced power management to reduce power consumption and help preserve battery life. The shared Power Management Logic coordinates Enhanced Intel SpeedStep Technology and idle power-management state (C-states) transitions in HW to efficiently manage voltage and frequency. This also enables the two execution cores to independently and dynamically transition to Halt, Stop Clock, and Deep Sleep low-power states. This means that if only one core is being utilized, the second core can still enter an idle state to help save power.
Digital Media Boost The Intel Core Duo processor features micro-architectural enhancements for improved floating point capability, including instruction optimizations and performance enhancements for existing Streaming SIMD Extensions 2 (SSE2). In addition to enhancing the performance of existing Streaming SIMD Extensions 2 (SSE2), there are 13 new instructions that further extend the capabilities of Intel® processor technology. These new instructions are called Streaming SIMD Extensions 3 (SSE3), first introduced on the Intel® Pentium® 4 Processor, with their implementation fully optimized specifically for the Intel Core Duo processor Architecture.
-
These instructions accelerate activities such as complex arithmetic, graphics, and synchronization of multiple threads. The Intel Core Duo processor also features other floating point performance enhancements such as a faster integer divide and updated micro-ops fusion. These new micro-architectural enhancements lead to improved throughput and performance.  With all the Enhanced technology and features that create this new Centrino Core Duo it take mobile technology to a new level for the personal user and the professional user.

Intel Mobile 945 Express Chipsets

The Mobile i945 Express Chipset (aka "Calistoga") is another part of the equation to the Napa platform similar to last generation Sonoma platform which offer power, mobility, and connectivity.  In addition, the 945 Express is promise to offer everything what it's predecessor Sonoma have, and much more.  The 945 Express chipset is a redesign of the 915 Express chipset, which is still being develop in 130nm process but promise lower power consumption and faster clock.

The new ICH7M (Southbridge) incorporates more aggressive clock gating (turning off the clock supplied to various blocks of the ICH when not in use) and IO buffer gating (turning off the IO buffers when not in use) to achieve lower power usage.  The front side bus (FSB) has been increase from 533MHz to 667MHz, which is a 25% increase in performance, dual-channel DDR2-667 (10.67 GB/sec), Intel GMA950 (2x improvement in graphics performance), PCIe x1 I/O interface (3.5x the bandwidth), and so forth.  Intel launches two version of the mobile 945 Express chipset: mainstream chip mobile 945GM Express and performance chip mobile 945PM Express.

Intel's new logo for Centrino Duo platform

Intel is taking a big leap ahead from it's competitors in this year of 2006.  With the new redesign of last year Centrino mobile to Centrino Duo it is obvious that a new logo is necessary to spice up the new technology. The new Centrino logo looks lighter and have curve.  The Centrino Duo logo is an authentication for Core Duo "Yonah" microprocessors and Centrino logo is an authentication for Solo "Yonah" microprocessors. The simple equation below distinguishes what Centrino logo to use for notebook builder.
