CPU Comparison
Core i7-12850HX vs Intel Core i7-13850HX
A side-by-side comparison of specs, performance and value. The Intel Core i7-12850HX is a specialized variant of the 12800HX, launched in May 2022. It shares the exact same Alder Lake-HX architecture, 10nm process, 16-core (8P+8E), 24-thread configuration, and 55W base TDP. The key differentiator lies in its support for ECC (Error Correcting Code) memory and enterprise-specific features like vPro, making it suitable for professional workstations where data integrity is paramount. It operates at a slightly higher base clock of 2.1 GHz compared to the 12800HX, while maintaining the 4.8 GHz turbo boost. It features 25 MB of L3 cache, 20 PCIe 5.0 lanes, and Intel UHD Graphics 770. While core overclocking is limited, DRAM overclocking is fully enabled, allowing memory tuning alongside ECC stability. This CPU bridges the gap between enthusiast gaming and professional mobile workstation markets.
