What Are the Components of an X99 CPU

A gaming PC is a significant investment made to serve for a long time. That is why the components of a PC need to be given a fair share of attention to ensure you are buying a system that would fit all your digital needs. Here we have explained a few of the most essential components that make or break a PC.

Direct Media Interface

To develop a connection between itself and the processor, the X99 chipset uses a Direct Media Interface (DMI) 2.0 x 4 link providing a total bandwidth of 20Gbits/s to all connectivity points offered by the chipset.

Intel Core i7-5820K

PCI Express 3.0 Lanes

The PCI Express 3.0 lanes are configurable, and a layout is provided by the processor that is supported by the X99 chipset. Although the number of lanes provided depends upon the processor, however, the lanes may be bifurcated into two x16 links and one x8 link.

Serial ATA 3.0 Controllers

The X99 chipset is integrated two Serial ATA (SATA) controllers providing up to 10 ports for storage speeds with up to 6bits of supporting speed per port. Along with that, hardware support is also provided for Advanced Host Controller Interface (AHCI). After the integration of one Extensible Host Controller Interface (xHCI) and two Enhanced Host Controller Interface (EHCI) controllers, a total of 14 USB ports are provided by the system.

What to Look For When Buying an X99 CPU

Choosing a CPU is a challenging task. All things work in unison to process loaded games and produce high-end graphics. A few components dominate the others and cannot be compromised upon. Here we have discussed a few of the features which make a CPU great.

The Processor

For an X99 motherboard, Intel is the only way to go. Intel compressors are more robust when it comes to gaming compared to AMD. From amongst the full range of well-performing Intel processors, the X99 is compatible with Core i7 compressors. If you are building your own CPU with X99 as a motherboard, be sure to choose the Core i7 compressor.

The Memory

The X99 supports memories up to 3200 MHz. It also fully supports the DDR4 memory system as well as the quad-core memory system to enhance the bandwidth to 256bits or higher for higher performance.

Memory Cards

With the X99, you can support multiple GPUs as well as crossfire them. Usually, it supports three Graphics Cards, but models like ASUS X99_-A can support up to four Graphic Cards for an ultra-rich and impressive gaming experience.

Review of the Best X99 CPUs

Here you will find the reviews of some of the most prominent and well-performing units in the market. 

Best Overall:
Intel Core i7-5820K

Pros and Cons of X99 CPUs

If you are not convinced or confused about which X99 CPU to invest in, then here is a list of some pros and cons to help you decide better. 


The following are some pros of this kind of X99 CPU:

Increased Core Count

Multiple core architecture enhances the productivity of a system running concurrent applications where each core could handle a different thread of data. Hyperthreading capability additionally enhances the functionality, even more, allowing each core to handle more than one thread.

Multiple GPU Support

The X99 motherboard can support up to 3 GPUs allowing crossover to greatly enhance the gaming experience without causing graphical delays or system crashes.

More PCle Lanes

The X99 system have the capacity to support a considerable amount of PCle 3.0 lanes for expanding the capabilities of the system. To the lines, high-end components could be connected to carry out some of the most intensive tasks and at exceptionally great speeds.


However, it comes with some drawbacks, including:


The X99 motherboard is a powerful device that utilizes the best components in its built and offers services that are expected of a high-end motherboard. Its usability is, however, limited to a confined fraction because of the very large sum of money it is sold for.

Heat Generation

With so many cores working to their fullest with the rest of the components being challenged beyond thresholds as well, quite a lot of heat is generated by the system. Which also limits the overclocking possibilities. The systems mostly lack heat sinks or cooling systems to counter the problem.

How to Install an X99 CPU

Follow the following steps to install the X99 CPU correctly:

1. Unbox your CPU sockets and get the motherboard ready as well.

2. On the motherboard, you'll see two levers, left and right, that will lock your CPU in place.

3. Press on the left lever and slide right to free it from the locks. Similarly, press on the right level and slide it left.

4. The socket cover would now open.

5. Notice a mark on the bottom left corner of the CPU that will correspond to a mark on the motherboard.

6. Match the corners with the marks and guide the CPU onto the motherboard.

7. Gently drop it over the motherboard, and without applying any force to the CPU, let it sit there.

8. Remove the plastic covering from the socket cover by gently popping it upwards.

9. Pull up the locking levers and put the socket cover back in place.

10. Lock the lever in place.

11. Make sure not to allow any dust to enter the socket during the operation.

12. Save the plastic cover in case you need to RMA the motherboard as the shopkeepers won’t accept any motherboard that is missing the cover. 


The X99 CPUs are dynamic multiprocessing units, high-speed systems that can support heavy data processing and display incredible outputs. They are compatible with the best available devices and allow expandability for an enhanced experience. Efficient and high-speed data processing is what they were built for, and their deliverance matches their price.
