We?ve already taken a look at two processors in Intel's Core X-Series, the Core i9-7900X and the Core i7-7740X. Today we are checking out our third processor, which is the Core i7-7820X. This processor is another great entry into the Core X-Series and one that will make sense for a lot of people. It sits right below the Core i9-7900X in Intel's HEDT product stack and is not a terribly crippled part like the Core i7-7740X. The Core i7-7820X is an 8-core, 16-thread part with a base clock of 3.6 GHz and a boost clock of 4.3 GHz, and with two cores reaching up to 4.5 GHz with the new Turbo Boost 3.0 technology. You have 11 MB of L3 cache, quad-channel DDR4 support, and a TDP of 140W. The big difference between this chip and the Core i9 chips that sits above it is the PCI-Express lanes, which get cut from 44 down to 28. This comes at a more reasonable cost than the Core i9-7900X at only $599. Let's get this chip in our X299 test bench and see what it is all about.
