The term "NUC" refers to Intel's Next Unit of Computing, which is a small form factor computer. The number of cores in a NUC can vary depending on the specific model you are referring to, as Intel has released several generations of NUCs with different configurations.
The earlier NUC models typically featured dual-core or quad-core processors, while the newer models have expanded to include quad-core, hexa-core, and even octa-core options. Intel's latest NUCs, based on their 11th generation processors, offer up to 8 cores.
To determine the exact number of cores in a particular NUC model, it is best to refer to the specifications provided by Intel for that specific product. Pets Life
