Intel Core i7-8650U socket: BGA 1356

What the Core i7-8650U is

The Core i7-8650U is a four core, eight thread mobile processor for business ultrabooks. It launched in August 2017 with a 1.9 GHz base and up to 4.2 GHz Turbo at 15 W. The highest clocks in the Kaby Lake-R U set suit corporate buyers who need burst pace with management features.

Eight megabytes of Smart Cache support office suites with security agents. The 1.9 GHz base leads the U lineup for sustained work, while 4.2 GHz burst leads single thread peaks. Configurable TDP from 10 W at 800 MHz to 25 W at 2.1 GHz covers silent fleets and performance images.

UHD Graphics 620 drives business docks without a discrete card. Management firmware on corporate boards matters more than graphics pace here. Office meetings run encrypted drives and video calls on integrated output.

On 14 nm the 8650U solders to premium ultrabooks with DDR4 or LPDDR3. Intel listed it at $409 tray pricing. It sits above the consumer 8550U on base and burst for vPro style fleets.

Socket and motherboard compatibility

The 8650U solders to BGA 1356 with no socket path. Laptop model fixes the chip for life. Business SKUs add remote management on top of the same silicon.

Boards carry DDR4-2400 slots or soldered LPDDR3-2133 up to 32 GB. Slotted memory models age better for long fleets. The How to find your CPU socket type guide shows where to confirm BGA status.

The Core i7-8550U is the consumer quad core on the same package with slightly lower clocks. The Intel Core i5-8350U is the i5 business alternative on BGA 1356.

Memory, PCIe and cooling

DDR4-2400 or LPDDR3-2133 in two channels up to 32 GB is the official memory. Bandwidth near 37.5 GB per sec with DDR4 pairs helps calls and sharing. ECC is not supported.

Twelve PCIe 3.0 lanes wire NVMe SSDs and board devices. Corporate builds boot from encrypted SSDs on four lanes. Remaining lanes serve readers and LTE modules.

Fifteen watts need a thin fan and pipe. Ten watt down mode suits quiet travel, while 25 W up mode suits docked performance. Battery and SSD swaps are the main service items.

Upgrade paths

No CPU change is possible on soldered BGA 1356. Memory where slotted and SSD size are the only growth paths. A move to NVMe from SATA helps most.

Beyond this generation a new laptop brings more cores and newer memory. The LGA, PGA and BGA: CPU package types explained guide explains soldered business limits.
