LGA 2066 is a CPU socket made by Intel. It came out in 2017 for high-end desktop and workstation computers. LGA 2066 supports Intel’s Core X-series and Xeon W processors, which offer high core counts and strong performance for demanding tasks.
This socket replaced the older LGA 2011-3 socket. It works with the X299 and C422 chipsets. LGA 2066 CPUs have more pins than regular desktop chips. This allows them to handle more memory channels and PCIe lanes.
Many CPUs fit in the LGA 2066 socket. They range from 4-core chips to 18-core monsters. Some popular options include the Core i9-7980XE and Xeon W-2195. These CPUs are great for jobs that need lots of cores, like video editing or 3D rendering.

Comprehensive List of LGA 2066 CPUs
LGA 2066 CPUs come in two main series: Intel Core X and Intel Xeon W. These processors offer high performance for demanding tasks and support large amounts of RAM.
Intel Core X-Series
The Intel Core X-Series includes powerful CPUs for enthusiasts and professionals. The i9-10980XE is the top model with 18 cores and 36 threads. It has a base clock of 3.0 GHz and can boost up to 4.8 GHz.
Other popular models are the i9-10940X (14 cores), i9-10920X (12 cores), and i9-10900X (10 cores). These CPUs support quad-channel DDR4 memory and have 44 PCIe lanes.
The i9-9980XE and i9-9960X are older options with similar core counts. They offer slightly lower clock speeds but still provide strong performance.
For those on a budget, the i7-9800X and i7-7820X have 8 cores each. The i5-7640X is the most affordable option with 4 cores.
Intel Xeon W-Series
Xeon W CPUs target workstations and professional use. The W-2295 leads the pack with 18 cores and a 3.0 GHz base clock. It can boost up to 4.8 GHz and has 24.75 MB of L3 cache.
Other high-end models include the W-2275 (14 cores) and W-2265 (12 cores). These CPUs support up to 1 TB of ECC memory for improved reliability.
Mid-range options like the W-2245 and W-2235 offer 8 and 6 cores respectively. The W-2223 is an entry-level 4-core model for lighter workloads.
All Xeon W CPUs have Intel vPro technology for remote management and security features.
