7th Gen Intel Core i7-7820X Review

The 7th Gen Intel Core i9 7820X is an 8-core, 16-thread Skylake-X HEDT processor, running a 3.6 GHz base clock that boosts to 4.5 GHz within a 140 Watt TDP on the LGA2066 socket.

As the entry point into Intel's original LGA2066 HEDT platform launch lineup, this chip offered the genuine platform advantages of quad-channel memory and extensive PCIe lanes at a more accessible 8-core tier below the 7900X.

Platform

This HEDT chip requires an X299-series motherboard on the LGA2066 socket, typically paired with quad-channel memory for genuine workstation-scale bandwidth.

How Is the Core i9 7820X in Terms of Performance

With 8 cores and 16 threads, this chip offered the HEDT platform's genuine memory bandwidth and PCIe lane advantages at Intel's original LGA2066 entry tier, a more accessible option than the 10-core i9-7900X.

Benchmarks

As Intel's original Skylake-X HEDT entry-tier chip, this processor's genuine 8-core, 16-thread performance offered HEDT platform access at a lower core count and price than the flagship i9-7900X of the same generation.
