Many quad-core processors are composed of two separate dies, which means some cached data has to travel outside the processor to get from core to core. That’s an inefficient way to access information. Enter the Quad-Core Intel Xeon “Nehalem” processor. Its single-die, 64-bit architecture makes 8MB of fully shared L3 cache readily available to each of the four processor cores. The result is fast access to cache data and greater application performance. Combine that with the other technological advances and you get a Mac Pro that’s up to 1.9x faster than the previous generation.1 System memory is often connected to a processor through a separate I/O controller. But each Intel Xeon “Nehalem” processor features an integrated memory controller — another leap forward for workstation system architecture. By connecting memory directly to the processor, the new Mac Pro processors have faster access to data stored in memory, and memory latency is reduced by up to 40 percent. The integrated memory controller, along with fast 1066MHz DDR3 ECC SDRAM, also gives Mac Pro up to a 2.4x increase in memory bandwidth over previous generations.2 More bandwidth allows for more data to be fed to the processor faster, helping each core spend its time processing data, not waiting for information to arrive. And Error Correction Code (ECC) corrects single-bit errors and detects multiple-bit errors automatically. That’s especially important in mission-critical and compute-intensive environments. The new Mac Pro introduces Turbo Boost: a dynamic performance technology that automatically boosts the processor clock speed based on workload. If you’re using an application that doesn’t need every core, Turbo Boost shuts off the idle cores while simultaneously increasing the speed of the active ones, up to 3.33GHz on a 2.93GHz Mac Pro. The new Intel Xeon “Nehalem” processors support Hyper-Threading, which allows two threads to run simultaneously on each core. So an 8-core Mac Pro presents 16 virtual cores that are recognized by Mac OS X. Performance is enhanced because Hyper-Threading enables the processor to take better advantage of the execution resources available in each core. A new bidirectional, point-to-point connection — called QuickPath Interconnect — gives the Intel Xeon “Nehalem” processor quick access to the disk, I/O, and other Mac Pro subsystems. In the new 8-core Mac Pro, there’s a QuickPath Interconnect between the two quad-core processors as well. This connection acts as a direct pipeline, so processor-to-processor data doesn’t need to travel to the I/O hub first. It’s another way the new Mac Pro boosts performance across the board. Based on an industry-leading 45-nm process technology and combined with improved power management capabilities, the new Intel Xeon “Nehalem” processors are more energy efficient than before. So the Mac Pro is faster than ever, while using less energy when idle.

the Quad-Core Intel Xeon “Nehalem” processor

To build something truly different, you need to work in a truly different way. Apple designers and engineers work together through every stage of product development. It’s a partnership that makes innovation possible. And it’s exactly how the new DSI MacBook Pro Crystal Cover Case Red, 15.4 " Until now, all notebooks were designed the same way. By assembling multiple pieces to create a single enclosure. But once you include all the necessary parts, you add size, weight, complexity, and more opportunities for failure. Solving a problem like this required more than an incremental change. It required a breakthrough. To create the new DSI MacBook Pro Crystal Cover Case Red, 15.4 " Every MacBook starts its life as a single piece of aluminum. View Of course, building only one part creates its own set of challenges. When you have multiple parts that are fastened together, tolerances don’t need to be perfect. You have wiggle room, both literally and figuratively. But when one part is responsible for many functions, it’s critical to manufacture that part with absolute precision, down to the micron. Every time. Millions of times over. There was only one way to achieve this level of precision: mill the unibody from a solid block of aluminum using computer numerical control, or CNC, machines — the kind used by the aerospace industry to build mission-critical spacecraft components. When you pick up a new MacBook, you immediately notice the difference. The entire enclosure is thinner and lighter. It looks polished and refined. And it feels strong and durable — perfect for life inside (and outside) your briefcase or backpack. The thickness of a notebook depends on the technology inside. LCD displays typically use cold cathode fluorescent lamps, or CCFLs, to create light and project a picture onto a screen. But that poses two problems. First, these lamps require more space, so the display can be only so thin. Second, just like the fluorescent lights in your home or office, the ones inside a CCFL display take time to warm up before they reach full brightness. That’s a lose-lose situation. And it’s why Apple engineers chose LED backlight technology for the new DSI MacBook Pro Crystal Cover Case Red, 15.4 " An LED backlight creates the same amount of brightness in less space. So you can make the structure that houses an LED display much thinner. And unlike fluorescent lamps, an LED backlight reaches maximum brightness instantly. Look at the DSI MacBook Pro Crystal Cover Case Red, 15.4 " The new MacBook trackpad has no button because it is the button. That means there’s more room to track, more room to click — left, right, center, and everywhere in between — and one less part. Apple designers and engineers spent countless hours considering things like sensitivity (how much pressure triggers a click?), audio feedback (what does the click sound like?), and friction over the smooth glass surface (what does it feel like?). And that’s just the hardware. Apple software engineers had a large part to play in the development of the trackpad, too. They incorporated Multi-Touch gestures, including swipe, pinch, rotate, and the new four-finger swipe. The result is the largest, smartest, most ergonomic MacBook trackpad ever. It’s one of many details considered and reconsidered during the design process.
Redesigned. Reengineered. Re-everythinged.
Unibody Enclosure
There’s a story behind each part. Take the thumbscoop, for example. It’s the indentation that allows you to open the display. If the scoop is too deep, you put too much pressure on the display to open it. If it’s too shallow, you struggle to open the display. It may seem incidental, but if the thumbscoop is well designed, it makes the difference between a bad experience and a good one. The challenge of the thumbscoop was to create a crisply machined scoop that was still comfortable to use. The designers at Apple worked on hundreds of versions of the thumbscoop — even examining them under an electron microscope — to get it right.
Then there’s the sleep indicator light. An indicator is functional only when it’s indicating something. Look to the right of the thumbscoop. You see nothing. Until you close the display and your MacBook goes to sleep. Then an LED glow appears from inside the enclosure. How? During the CNC process, a machine first thins out the aluminum. Then a laser drill creates small perforations for the LED light to shine through. These holes are so tiny that the aluminum appears seamless when the light is off.
The marriage of electronics and mechanical design makes the new MacBook as advanced on the inside as it is on the outside. The internal architecture has been reengineered from the silicon up. There’s a new logic board. A new chipset. And a new integrated graphics processor — a feat of engineering in itself.
Many notebook computers sacrifice graphics performance in order to save battery life. The new MacBook offers the best of both worlds. The NVIDIA GeForce 9400M graphics processor provides up to five times the performance of the previous-generation MacBook without draining your battery. So you can experience high-performance graphics ideal for playing 3D games or watching video.
Because Apple designs both the hardware and the software for the new MacBook, it’s easier to improve things like energy efficiency. Software tells the hard drive to spin down when it’s not in use. It tells the display and battery indicator lights to dim in low-light conditions. And it helps decide whether the CPU or the graphics processor would be best suited to the task at hand. That’s the kind of smart, integrated design that sets MacBook apart from other notebooks.
A Greener Notebook
Made from recyclable aluminum and glass, the new MacBook is greener than ever. View
Top-to-bottom integration also makes MacBook greener than other notebooks. Complete control over how the new MacBook is designed, how it’s manufactured, and how it’s packaged gives Apple an environmental edge. Take the MacBook display, for instance. Conventional CCFL displays use mercury to create a backlight and arsenic to prevent irregularities in the glass. The LED-backlit display on the new MacBook, on the other hand, is both mercury- and arsenic-free. LED backlight technology also conserves energy: This display requires 30 percent less power than a CCFL display.
Mercury and arsenic aren’t the only toxins absent from the new MacBook. Many computer manufacturers have only pledged to eliminate polyvinyl chloride (PVC) and brominated flame retardants (BFRs) from their enclosures and circuit boards. Apple is removing not only PVC and BFRs, but all forms of bromine and chlorine throughout the entire MacBook.
Just how green is the new MacBook? It’s ENERGY STAR compliant, which means it meets the government standard for energy efficiency. It’s also earned EPEAT Gold status, the highest standard for environmental performance in the electronics industry. And every new MacBook is shipped in packaging that’s 41 percent smaller than any previous generation. That translates to fewer trees used for boxes and less fuel used to transport more MacBooks on fewer planes. And at the end of its long, productive life, you can recycle almost all of your MacBook.
Only Apple could make a notebook like this. Hardware and software. Design and engineering. Production and manufacturing. They’re all part of a single process at Apple. When you start using your new MacBook, you’ll discover what that means. The light and sturdy unibody protects the components inside. The LED-backlit display — along with the graphics processor that helps power it — gives you faster games and a brilliant canvas for your photos, movies, and more. The glass Multi-Touch trackpad feels as good as it functions. From the smallest detail to the biggest engineering breakthrough, the new MacBook truly is the next generation of notebooks.
