Intel Core i7-7820X X-Series Skylake-X 8C/16T CPU Review

Intel typically ships engineering samples in little black boxes such as the one above, but retail packaging will differ greatly from this. You will get a fancy box with Core i7 and a big X on it, but you still won't get a heat sink cooler.





The top of the CPU is identical to that of the 7900X, all the way to the little inactive RFID tag in the upper right-hand corner of the CPU. The CPU doesn't use solder between the die and internal heat spreader.




The CPU's bottom has many golden pads that fit into the LGA-2066 socket.



Test Setup





We are using MSI's X299 Gaming M7 ACK with two BIOS versions, 1.1 and 1.2. Version 1.2 comes with an updated CPU microcode and perhaps some MSI tuning, and I wanted to show how the BIOS version can affect performance.




CPUz screens show the BIOS version, cache sizes (1MB L2, 11MB L3), frequencies, and even TDP.
