10-core Skylake-X for X299 workstations
This processor targets workstations that need many threads for rendering, compilation or virtualisation. It fits the LGA-2066 socket and requires an Intel X299 chipset motherboard. The 10 cores and 20 threads handle parallel workloads that exceed mainstream desktop limits.
Sustained 140 W thermal envelope under load
At the 140 W TDP the chip can hold its 3.3 GHz base clock across all 10 cores during long sessions. Turbo peaks of 4.3 GHz appear on fewer cores when thermal headroom allows. A capable cooler is essential because no cooling device is included in the box.
LGA-2066 installation needs even pressure
The large 2066-land package demands careful alignment and firm, even mounting pressure to avoid bent pins or poor contact. Builders often forget to update the X299 BIOS before first boot, which prevents the system from posting. DDR4-2666 memory and a 44-lane PCIe 3.0 layout complete the platform requirements.

Questions about this item
How much heat does the 140 W TDP of the Core i9-7900X generate during sustained all-day workloads?
The processor has a 140 W thermal design power, so a cooler rated for at least that much heat is required to keep temperatures stable during continuous operation.
Which motherboard socket and chipset must I already own to install the Core i9-7900X?
You need an LGA 2066 socket motherboard based on the Intel X299 chipset; the CPU will not fit or function on any other platform.
Will my existing DDR4-2666 memory and PCIe 3.0 add-in cards work at full speed with this 10-core CPU?
Yes, the memory controller supports DDR4-2666 and the processor provides 44 PCIe 3.0 lanes, so current DDR4 modules and PCIe 3.0 devices operate at their rated speeds.
