Best LGA 2066 Motherboards

Best LGA 2066 Motherboards for i9-9960X i9-9920X & i9-9820X

Intel has recently launched high-end desktop parts. There are seven new LGA 2066 socket CPUs. The platform is also referred to as X299 platform. The range of CPUs offers from 8 to 18 cores. The i9 platform has six options while the i7 platform has one CPU with the X299 platform or the LGA2066 socket size. Let us check out a few motherboards that support these latest CPUs from team blue. Here is our select list of best LGA2066 motherboards for i9-9960X i9-9920X & i9-9820X.

Best LGA 2066 Motherboards for i9-9960X i9-9920X & i9-9820X

The new processors launched as part of its Skylake X Refresh include i9-9960X i9-9920X & i9-9820X. The six new CPUs launched in the new series have a TDP of 165 W and a jump of around 600 MHz compared to the previous generation of processors. These CPUs also come with a turbo frequency of 4.5 MHz and offer 44 dedicated PCIe lanes. Of these, the i9-9980XE is the flagship option and provides you access to a base frequency of 3.0 GHz.

In the case of Skylake-X processors, each CPU contains 1.375 MB of L3 cache. So a 10 core CPU will have access to 13.75 MB. Since the L3 cache is a non-inclusive, victim cache only in case of L2 cache buffer overflows will go into the L3 cache. So, on paper, there isn’t going to be a significant performance boost, unless a lot of repeat data is processed by the CPU.

However, for us, the major highlight is the 44 lanes of dedicated PCIe lanes. It helps the PC components to directly access the CPU rather than being routed through the chipset controller, thereby improving the performance.

The following is the list of new 9th Gen Intel X series CPUs from the recent announcement.

Socket compatibility is a good thing and in this case, all the earlier LGA 2066 motherboards are supported with a BIOS flash. However, motherboard manufacturers appear to be entirely supporting their existing lineups, and there are not many new launches visible. There are no new models launched or being launched any time soon. As we said, the current X299 based motherboards should support the new CPUs. Until the time new motherboards are available, we may need to keep up with the current set of options alone.

Here is a quick look at the Intel X299 (Basin Falls) processor family from last year.

Before We Take Your leave….

Those are few motherboards with LGA 2066 socket and support for i9-9960X i9-9920X & i9-9820X. Not that this is NOT an exhaustive list. There are several other options you can check out. However, the CPUs have just been made available, and we would expect more motherboards designed explicitly for the processors would be made available soon.

However, the Intel partners already have a few motherboards with the LGA 2066 socket support and though a couple of them have been manufactured for the Intel Core i7 & i9 7th Gen processors, it now supports the new i9 processors as well. We will be updating this post as and when new motherboards are introduced.

Do share your experiences if you have used any of the motherboards that have been featured in this compilation. In case you are aware of any newer motherboards that support the new i9-9960X i9-9920X & i9-9820X CPUs, do share them and their details with us.
