Intel i9-9900K – 9th generation Intel Processor

Intel i9-9900 is the ninth generation processor from the family of Intel i9 core processors. The processor has been around for quite some time now. It was launched in Q4 of 2018. It can be bought for under $400 from one of the processor merchant places. And, it offers cutting-edge performance. We look at a few user-generated queries about the Intel i9-9900K CPU and its performance metrics.

Does Intel i9-9900K have integrated graphics?

Yes, the Intel i9-9900K processor does have integrated graphics. It has UHD 630 integrated graphics. The salient features of the graphics on Intel i9-9900K are mentioned herein:

  • Base frequency of the i9-9900K processor – 350 MHz.
  • Max frequency of the i9-9900K processor – 1.20 GHz.
  • Graphics Max Video Memory – 64 GB. This means that the processor can use up to a maximum of 64 GB of physical memory for graphics processing.
  • DirectX 12 support and OpenGL 4.5 standards are supported by the Intel i9-9900K processor.
  • 4K support at 60 Hz is supported by the Intel i9-9900K processor.

Does Intel i9-9900K support 3200 MHz RAM?

Intel i9-9900K supports DDR4-2666 RAM. This means that i9-9900K will work with RAM at 2666 MHz speed. The bandwidth through the RAM for an Intel i9-9900K is 41.6 GB/s. Having said that, if you are getting a 3200 MHz RAM module, you can try to install it on the system if the motherboard supports 3200 MHz modules. If supported by the motherboard manufacturer, your system will try to find the optimum speed for the installed RAM module. If it is not able to go beyond the 2666 MHz, the RAM speed will be downgraded to work with your computer’s resources. Or else, you may get better than 2666 MHz speed as the RAM module may eventually settle at a speed that is slightly higher than 2666 MHz.

3200 MHz RAM modules are backward compatible. If your computer’s motherboard does not support 3200 MHz modules, the RAM module will automatically work at the frequency supported by the motherboard.

On a similar note, if you get a 3600 MHz RAM module, you can still install it on a compatible motherboard. I9-9900K, however, will work at speeds of 2666 MHz.

Which chipset is compatible with Intel i9-9900K processors?

Intel i9-9900K supports LGA1151 socket. Motherboards that are compatible with the LGA1151 socket would do well in housing the Intel i9-9900K processor. The following Intel chipsets are compatible with the Intel i9-9900K processors:

  • Intel Z390 chipset
  • Intel Z370 chipset
  • Intel B365 chipset
  • Intel B360 chipset
  • Intel Q370 chipset
  • Intel H370 chipset
  • Intel H310 chipset

Out of these chipsets, it would be best to choose a motherboard that is based on the Intel Z390 chipset. You will need to get an Intel LGA1151 socket motherboard in the 300 series. The 300 series LGA1151 socket motherboards support Intel 8th and 9th generation processors.

Does Intel i9-9900K support PCIe 4?

Intel i9-9900K is a PCIe 3 compatible processor. The Peripheral Component Interconnect Express (or PCIe) is a high-speed serial computer expansion bus standard for attaching hardware devices to a computer. The different PCI Express versions support different data rates. i9-9900K supports a maximum of 16 PCIe channels for sending or receiving data.

A PCIe 3 compatible processor implies that the data transmission would happen at rates of 1 GB per second per lane. i9-9900K supports maximum 16 PCIe lanes, thereby achieving a max data speed of 16 GB/s.

Is Intel i9-9900K compatible with Windows 11?

Yes, the Intel i9-9900K processor is compatible with Microsoft Windows 11. You can find out from Microsoft’s list of compatible processors that the i9-9900K is supported by Windows 11. i9-9900K is compatible with the TPM 2 requirements for Windows 11 to work on a computer. Your new computer may come preloaded with Windows 11. Or, if you are running Windows 10, your system should get a natural upgrade to the Windows 11 operating system.

Most Intel i9-9900K based computers would have already gotten the Windows 11 update through the Windows Update program. You will also continue to receive security updates, monthly rollup updates, and features updates for the Windows 11 operating until it becomes the end of support.

Is Intel i9-9900K compatible with Intel Z490 chipset?

No, the Intel i9-9900K processor is not compatible with the Z490 chipset. Z490 chipset is for the 10th and 11th generation Intel processors. Intel i9-9900K is a 9th generation processor that is compatible with the Z390 and Z370 chipsets.

i9-9900K is a 37.5 x 37.5 mm processor that is compatible with the LGA1151 socket. So, ideally, you must be looking at getting a motherboard that is compliant with the LGA 1151 (300 series) socket for the i9-9900K to be compatible. Z490 is an LGA1200 socket that works on PCIe 4 standards. You will not be able to make use of the Z490 chipset motherboard for the Intel i9-9900K processor.


For the i9-9900K processor, we can summarize the major points below:

  • it is compatible with Windows 11.
  • it is compliant to PCIe 3 standards with 1 x 16 PCI lanes.
  • you need a LGA1151 (300 series) compatible motherboard.
  • it has TPM 2 to support hardware based security for Windows 11.
  • it has support for Intel UHD 630 integrated graphics.
  • it supports DDR4-2666 RAM, although it can try to work with higher rated RAM if your motherboard supports.
