Intel Computex 2024 Recap: Lunar Lake CPU & Xe2 GPU Architecture Debut, Xeon 6 "Granite Rapids" & "Sierra Forest" CPUs Unveiled
How does the performance of the Lion Cove and Skymont cores in the Lunar Lake CPUs compare to their predecessors?
The Lion Cove and Skymont cores in the Lunar Lake CPUs show significant performance improvements compared to their predecessors. The Lion Cove architecture has witnessed a 14% improvement in IPC (instructions per cycle) compared to its predecessor. On the other hand, the Skymont cores have recorded a 38% improvement in single-threaded integer performance and a 68% improvement in floating-point performance compared to the Crestmont E-Cores on the Meteor Lake CPUs1. These improvements are due to various architectural enhancements and optimizations made by Intel.
What are the connectivity enhancements introduced with the Lunar Lake CPUs?
The Lunar Lake CPUs introduce several connectivity enhancements, including support for Wi-Fi 7 and Bluetooth 5.4. The integrated Wi-Fi 7 solution on Lunar Lake has a 28% smaller silicon size compared to the BE 200 networking interface, resulting in faster speeds. The Lunar Lake laptops will feature up to 3 Thunderbolt 4 ports, offering up to 25% better read and write speeds with Thunderbolt 5 SSDs. These experiences will be accelerated using Thunderbolt Share, which adds a new level of productivity by allowing multi-PC connectivity. Additionally, Lunar Lake features RF Interference Mitigation Technology, which dynamically adjusts the DDR clock frequency, significantly impacting Wi-Fi performance. The most significant aspect of the Wi-Fi 7 integration on Lunar Lake SOCs is the Multi-Link Operation (MLO), which increases reliability, boosts throughput, improves latency, and enables traffic separation/differentiation.
What are the key features of Intel's new Lunar Lake CPU architecture presented at Computex 2024?
Intel's new Lunar Lake CPU architecture, presented at Computex 2024, boasts several key features that aim to revolutionize the computing industry. Some of these features include:
-
Hybrid Design: Lunar Lake employs a hybrid design with a combination of Performance (P) cores and Efficient (E) cores. The P cores are based on the Lion Cove architecture while the E cores are based on the Skymont architecture. This design allows for significant performance gains while maintaining power efficiency.
-
Improved IPC: The Lion Cove core architecture has seen a 14% improvement in instructions per clock (IPC) compared to its predecessor. The Skymont E-cores have also seen a 38% IPC gain in single-threaded integer performance and a 68% IPC gain in floating-point performance.
-
Onboard NPU: Lunar Lake features Intel's "NPU 4" for high-end AI processing. The integrated NPU delivers 48 TOPS of AI compute power, a 4.36x increase over the NPU in Meteor Lake SOCs, which offered just 11 TOPS.
-
Connectivity: Lunar Lake brings in additional connectivity options, such as support for Wi-Fi 7 and Thunderbolt 4.
-
Xe2 GPU Architecture: Lunar Lake will debut with the new Xe2 architecture, featuring enhanced vector engines, deeper caches, new XMX engines, and larger ray tracing units. The onboard Xe2 GPU will feature 8 Xe2 cores, each with 8 XMX and 8 Vector units, a Load/Store unit, a Thread Sorting Unit, and a dedicated L1/L2 cache.
-
Efficiency: Lunar Lake is designed to be power efficient, with a focus on delivering high performance while minimizing power consumption.
These features make Lunar Lake a highly efficient and powerful CPU architecture, promising significant advancements in both performance and AI capabilities.
