Intel 2010 Core i5 Features

  • Dual-core processing 32nm dual-core processing runs two independent processor cores in one physical package at the same frequency.
  • Turbo Boost Technology Automatically speeds up your processor when your PC needs extra performance— that's smart performance with a speed boost. Available in select models of the new 2010 Intel Core i5 processor-based systems.
  • Hyper-Threading Technology Features 4-way multi-task processing that allows each core of your processor to work on two tasks at the same time, delivering the performance you need for smart multitasking. You and your PC won't be slowed down, regardless of how many applications you have open at once.
  • HD Graphics Intel HD Graphics provides superb visual performance for sharper images, richer color, and life-like audio and video. Watch movies and Internet videos in high-definition, play popular game titles and get full support for Microsoft Windows 7. It's all built in; no need for an extra add-in video card.
  • Integrated memory controller enables two channels of high-speed DDR3 1333 MHz memory. This memory controller's lower latency and higher memory bandwidth delivers amazing performance for data-intensive applications.
  • Intel Smart Cache is a shared cache dynamically allocated to each processor core, based on workload. This efficient, dual-core-optimized implementation increases the probability that each core can access data from the fast cache, significantly reducing latency to frequently used data and improving performance. Optimized for industry-leading multi-threaded games.
