Intel Core i9 9940X 14-core LGA2066
The 14-core, 28-thread design with a 4.4GHz boost clock and quad-channel DDR4 memory delivers strong parallel throughput for heavily threaded workloads. Its unlocked multiplier on the X299 platform provides headroom for overclocking, though the 165W TDP and 88°C thermal ceiling demand robust cooling. This processor is best for workstation users running sustained multi-threaded renders or simulations who already own an LGA2066 motherboard.
