Architecture Breakdown
11th Gen Intel Core (Rocket Lake)
- Microarchitecture: Built on the Cypress Cove architecture, an evolution of the previous Sunny Cove architecture utilized in mobile CPUs.
- Process Technology: Utilizes the 14nm++ process node, which limits the number of cores and increases power consumption compared to newer generations.
- Core Count: Typically features up to 8 cores and 16 threads for the i7 models.
- IPC Improvements: Claims up to a 19% increase in instructions per clock (IPC) compared to the 10th generation, optimizing single-threaded performance significantly.
12th Gen Intel Core (Alder Lake)
- Microarchitecture: Introduces a hybrid architecture combining Performance-cores (P-cores) and Efficiency-cores (E-cores), allowing for a more dynamic approach to task management.
- Process Technology: Built on an advanced 10nm process, enhancing overall efficiency and thermal management.
- Core Count: Core i7 models can feature up to 12 cores (8 P-cores and 4 E-cores) with hyper-threading support on P-cores, optimizing performance in multi-threaded applications.
Performance Analysis
General Performance
- 11th Gen: Primarily focuses on enhancing single-threaded performance, making it a solid choice for gaming and applications that benefit from higher clock speeds. The integrated Intel UHD Graphics with Xe architecture also enhances media handling capabilities.
