Core i9-9920X Details

Ranking #148 of 2060 in overall performance, the Intel Core i9-9920X remains a high-end desktop processor from the 9th Gen X-Series, launched in October 2018. Despite being over seven years old as of early 2026, it still holds its own in certain workloads, particularly in applications that benefit from high core counts and advanced instruction sets. Its position in the broader CPU landscape reflects its status as a premium offering during its era, though it now sits well below the current top-tier processors in both single-core and multi-core performance.

The Core i9-9920X is built on Intel's Skylake-X Refresh microarchitecture, fabricated on a 14 nm process node. It features a 12-core, 24-thread configuration, enabled by Intel Hyper-Threading, which allows it to efficiently handle heavily threaded workloads. With a base clock of 3.5 GHz and a maximum turbo frequency of 4.4 GHz, it delivers strong single-threaded performance, though it trails behind modern processors in this category. The chip includes 19.25 MB of L3 cache, 12 MB of L2 cache, and 0.75 MB of L1 cache, supporting fast data access across all cores.

Equipped with Intel's advanced vector extensions, including AVX-512, AVX2, and AVX, the Core i9-9920X excels in compute-intensive tasks such as video encoding, 3D rendering, and scientific simulations. It supports DDR4-2666 memory across a quad-channel memory interface, with a maximum memory bandwidth of 79.47 GiB/s, though the actual memory bandwidth achieved is reported at 85.3 GB/s. The processor operates at a TDP of 165 W, requiring robust cooling solutions due to its high power consumption and heat output.

In benchmark testing, the Core i9-9920X achieves a single-core score of 6218, placing it at #197 in the single-core rankings, and a multicore score of 6430, ranking #166 in multicore performance. The overall score of 6303 positions it at #148, indicating that while it remains competitive in multicore applications, it is outpaced by newer processors in both efficiency and peak performance. It is notably slower than the top-ranked Core Ultra 9 285K, which scores over 8,700 in single-core tests, highlighting the generational gap.

The Core i9-9920X does not include integrated graphics, requiring a discrete GPU for display output. It supports a wide range of technologies, including Intel Turbo Boost Max Technology 3.0, Intel VT-x, Intel VT-d, and Intel SpeedShift, enhancing performance and virtualization capabilities. It uses the FCLGA-2066 socket, making it compatible with the LGA-2066 platform, and supports up to 128 GB of DDR4 memory.

As of March 2026, the Core i9-9920X is best suited for legacy systems or users who require a high-core-count processor for professional workloads such as content creation, engineering simulations, or server applications. While it no longer represents the cutting edge of performance, its robust feature set and strong multicore capabilities make it a viable option for specific use cases where cost and availability are key factors.
