Intel introduced three Core i7 laptop processors, the Core i7 920XM, Core i7 820QM, and Core i7 720QM. The base clock speeds of these quad-core processors is not very high, but the Turbo Boost mode can deliver gains of up to 75 percent for one individual core in single-threaded applications. Here's a brief overview of the specifications of these new chips:
These processors in addition to the new Intel® PM55 Express Chipset, provide the best laptop experience for intense gaming, digital media, photos, music, business applications and other multi-threaded software that hungers for faster processing speed. The chips also boost overall performance when using several of these applications simultaneously.
"With intelligent features like Intel® Turbo Boost Technology1, Intel® Hyper-Threading Technology2 and a host of others, Intel has revolutionized the laptop PC processor, delivering performance when you need it, energy efficiency when you don’t," said Dadi Perlmutter, executive vice president and general manager, Intel Architecture Group. "For the first time, mobile users can choose a laptop that delivers Internet-server like speed, right in their laps for the most demanding tasks, from intense gaming to digital video editing and social media applications."
Formerly codenamed "Clarksfield," Intel® Core™ i7 mobile processors offer Intel® Turbo Boost Technology1, which can accelerate the processor clock speed up to 75 percent to match workloads, as well as better performance on highly threaded applications with the power of Intel® Hyper-Threading Technology. The new Intel® Core™ i7 mobile processors also include two-channel DDR3 1333 MHz memory support and full 1 x16 or 2 x8 PCI Express* 2.0 graphics. Whether users are editing a video, composing a song, playing a video game or updating their Facebook* status with the latest YouTube* video craze, Intel® Core i7 mobile processors adapt to provide the right processing power for the task, with more performance and flexibility to match their on-the-go needs.
Laptops with Intel® Core i7 mobile processor Extreme Edition support Intel® Extreme Memory Profiles (Intel® XMP) and Intel® Extreme Tuning Utility, the ultimate tuning utility making it possible to overclock and fine tune your laptop for incredible performance and battery life optimizations. In addition, the Intel® PM55 Express Chipset enables high-end workstation and gaming laptops to support features such as Intel® Matrix Storage Technology, Intel® High-Definition Audio, and increased I/O interfaces.
