With AMD's Threadripper release on the horizon, today we are going to take a look at an Intel offering, the 8-core 16 thread i7-7820X. Last year, no one would have thought that Intel would sell their 8-core 16 thread CPUs for less than $1000, but today you can scoop one up for less than $600.

Competition from AMD with less expensive 8 and 6 core parts has pushed Intel to change its pricing model, and the result is significantly more affordable Intel HEDT CPUs such as the 7820X.

Today, I will not only look at the 7820X, but I will also look at how much impact BIOS updates can have on CPU performance, as I will test the 7820X using the same motherboard, but two different BIOS versions.



The 7820X has a base frequency of 3.6GHz, compared to the 7900X's 3.3GHz base. Turbo Boost 2.0 will boost cores towards 4.3GHz, and Turbo Boost Max 3.0 will take your two best cores to 4.5GHz. The 8-core 16 thread CPU uses 11MB of L3 cache and 1MB L2 per core, offers quad channel DDR4 2666MHz memory support, and comes in with a 140W TDP. The CPU offers 28 PCI-E lanes for GPUs and the like, with the X299 PCH offering up 24 more lanes for devices.


The 7820X has an MSRP of $599, but Newegg has it priced at $659.99 while Amazon has it priced right below $600 at this time. You should check out to see how Amazon's 7820X pricing has moved over the past few weeks.
