Intel Core i9 10920X 12-core LGA2066
Twelve cores and 24 threads with a 4.8GHz boost clock deliver strong multi-threaded throughput for heavily parallelized workloads, backed by quad-channel DDR4 memory support up to 256GB. The unlocked multiplier on the LGA 2066 socket provides straightforward overclocking headroom, though its 165W TDP and 14nm architecture result in a low efficiency score of 59.7. This processor is best for workstation users running sustained CPU renders or simulations who prioritize core count over single-thread speed and power consumption.
