Intel Core i9-9940X 3.3 GHz 14-Core LGA 2066 Processor has a base clock speed of 3.3 GHz and comes with features such as Intel Optane Memory and SSD support, AES-NI encryption, Intel vPro technology, Intel TXT, and Intel VT-d virtualization technology for directed I/O. This processor features a boost speed of up to 4.4 GHz, or up to 4.5 GHz with Intel Turbo Boost Max 3.0 technology. Additionally, this processor features 14 cores with 28 threads in an LGA 2066 socket, has 19.25MB of cache memory, and supports up to 44 PCIe lanes. Having 14 cores allows the processor to run multiple programs simultaneously without slowing down the system, while the 28 threads allow a basic ordered sequence of instructions to be passed through or processed by a single CPU core. This processor also supports DDR4 RAM and utilizes 9th-generation technology. If you need even more performance, this processor is unlocked, which lets you overclock the processor over its maximum speed. However, this is not recommended, as it will void the warranty.
