The second-generation Intel Core i5 processor was released in 2011 and was a significant improvement over its predecessor, the first-generation Core i5. The second-generation Core i5, also known as Sandy Bridge, was based on a new microarchitecture that improved performance, energy efficiency, and overall system responsiveness.
The Intel Core i5-2xxx series processors were available in dual-core and quad-core configurations, with clock speeds ranging from 2.5GHz to 3.4GHz. They also included Intel Turbo Boost Technology 2.0, which automatically increased the clock speed of the processor when needed to handle demanding tasks.
One of the standout features of the second-generation Intel Core i5 processor was its support for Intel Hyper-Threading Technology, which allowed each physical core to handle two threads simultaneously. This technology improved overall system performance by enabling the processor to handle more tasks at once.
The second-generation Intel Core i5 processor also featured Intel’s Advanced Vector Extensions (AVX), which improved the performance of floating-point calculations used in tasks such as video editing and image processing.
In addition, the second-generation Intel Core i5 processor included Intel’s Quick Sync Video technology, which improved video encoding and decoding performance, and Intel Wireless Display (WiDi) technology, which allowed users to wirelessly stream content from their computers to a compatible display.
Overall, the second-generation Intel Core i5 processor represented a significant improvement over its predecessor and helped to establish Intel as a leader in the computer processor market. It was a popular choice for mid-range desktops and laptops and remains a capable processor for many modern computing tasks.
