With previous generation Intel® Core™ i7 processors access multiple applications faster and unleash incredible digital media creation. Experience great performance for everything you do with the combination of Intel® Turbo Boost Technology and Intel® Hyper-Threading Technology (Intel® HT Technology), which maximizes performance to match your workload.
Intel® Turbo Boost Technology maximizes speed for demanding applications, dynamically accelerating performance to match your workload—more performance when you need it the most.
Intel® HT Technology enables highly threaded applications to get more work done in parallel. With 8 threads available to the operating system, multi-tasking becomes even easier.
Intel® Smart Cache provides a higher-performance, more efficient cache subsystem. Optimized for industry leading multi-threaded games.
Integrated memory controller enables three channels of DDR3 1066 MHz memory, resulting in up to 25.6 GB/sec memory bandwidth. This memory controller's lower latency and higher memory bandwidth delivers amazing performance for data-intensive applications.
