Intel Core i9-9900X

The Intel Core i9-9900X packs 10 cores and 10 threads. Clocks span 3.5GHz base to 4.4GHz boost. It drops into the LGA2066 socket with a 165W TDP — about 16.5W per core. 16MB of L3 cache helps in cache-sensitive games and workloads. Confirm motherboard socket compatibility before anything else, then size the cooler to the TDP.

Its $497.00 price tag places it squarely in high-end territory. PlanMyPC's builder flags compatibility problems automatically and tracks the latest processor deals from multiple stores.
