Core i9-9980XE Details

Ranking #97 of 2060 in overall performance, the Intel Core i9-9980XE remains a notable performer in the high-end desktop segment despite its age. Launched in October 2018, this processor is now over seven years old, placing it firmly in the category of legacy high-performance CPUs. While newer generations from both Intel and AMD have surpassed it in both single-core and multi-core performance, the i9-9980XE still holds its own in specific workloads due to its massive core count and robust feature set. As of March 2026, it sits well below the current top-tier processors like the Ryzen Threadripper PRO 9995WX or Core Ultra 9 285K, but still outperforms many mainstream and mid-range CPUs in multicore tasks.

Built on Intel’s Skylake-X Refresh microarchitecture at a 14 nm process, the Core i9-9980XE is designed for extreme workloads, featuring 18 cores and 36 threads enabled by Intel’s Hyper-Threading technology. Base clocked at 3.0 GHz with a turbo boost up to 4.4 GHz, the processor leverages Intel Turbo Boost Max Technology 3.0 to dynamically adjust performance based on thermal and power headroom. It supports up to 131 GB of DDR4-2666 memory across four channels, with a maximum memory bandwidth of 79.47 GB/s, though actual bandwidth measured at 85.3 GB/s due to optimized memory controller design. The L3 cache is a substantial 24.75 MiB, while L1 and L2 caches total 1.125 MiB and 18 MiB respectively, contributing to strong data access efficiency.

The i9-9980XE operates at a TDP of 165 W, indicating high power consumption and requiring an advanced cooling solution, especially when overclocked. It uses the FCLGA-2066 socket, part of the LGA-2066 platform, and supports PCIe 3.0 with up to 44 lanes directly from the CPU. The absence of integrated graphics means it requires a discrete GPU for any visual output. Despite its age, the processor includes a full suite of modern instruction sets, including AVX-512, AVX2, AES-NI, and Intel VT-x/VT-d virtualization support, making it suitable for content creation, scientific computing, and virtualization environments.

In benchmark tests, the Core i9-9980XE achieves a single-core score of 6,367, ranking #153 among 2060 processors, and a multicore score of 7,102, placing it at #93. The overall score of 6,661 positions it at #97, indicating that while its single-core performance is competitive, its multicore strength is more pronounced. The processor outperforms its predecessor, the Core i9-9960X, but trails behind newer Intel and AMD offerings such as the Ryzen 7 9700X and Core i9-14900HX. It also falls short of the top 50 multicore performers, where scores exceed 7,600, but it remains ahead of many server and workstation-grade processors in the same generation.

In conclusion, the Intel Core i9-9980XE is a powerful but aging processor best suited for legacy systems or users who require high core counts and AVX-512 acceleration without the need for the latest single-core performance. Its high price point and power demands make it less appealing in today’s market, but it remains a viable option for professional workloads in systems already built around the LGA-2066 platform. For new builds, modern alternatives offer superior efficiency and performance, but the i9-9980XE still represents a significant milestone in Intel’s high-end desktop lineup.
