Intel details its next-generation client architecture, code-named “Alder Lake”

At Architecture Day 2021, Intel detailed the next-generation client architecture, code-named “Alder Lake”.

Alder Lake will be Intel’s first performance hybrid architecture that includes a Performance-core and an Efficient-core to provide significant performance across all workload types. Intel also detailed the new Efficient-core and its Performance-core x86 CPU units that will power the Alder Lake.

• The Efficient-core microarchitecture is designed for throughput efficiency and efficient offloading of background tasks for multitasking. It runs at low voltage and creates headroom to increase frequency and ramp up performance for more demanding workloads. The new Efficient-core will deliver same performance when compared to Skylake core but with 40% less power.
• The Performance-core microarchitecture is designed for speed, the highest performing CPU core Intel has built. It pushes the limits of low latency and single-threaded application performance and provides a significant boost at high-power efficiency that can better support large applications. Intel claims that this new Performance-core will deliver 19% better performance over 11th gen cores.

To make both the cores work seamlessly with the OS, Intel developed Intel Thread Director that will enable the OS to place the right thread on the right core at the right time. Also, Alder Lake will power devices ranging from ultra-portable laptops to enthusiast and commercial desktops.
