BGA 1598 socket: CPUs, chipsets and cooler fit
BGA 1598 is the Intel soldered ball grid array package with 1598 balls for Tiger Lake-UP4 mobile processors from the first quarter of 2021. The package solders directly to thin laptop boards for small designs that need a lower power envelope than the UP3 stack. There is no socketed upgrade path.

Overview
The platform pairs 4 Willow Cove cores with Iris Xe graphics for thin machines that need responsive single thread pace in a small body. The lead example is the Intel Core i7-1180G7 with 4 cores and 8 threads, 12 MB of Intel Smart Cache, a 2.2 GHz base at 15 W and boost to 4.6 GHz. Memory runs LPDDR4x up to 4267 MT/s in two channels to 32 GB.
Because the processor solders to the board there is no socket retention and no processor upgrade. Laptop makers design cooling around the 15 W base with headroom for short turbo bursts, and buyers choose the configuration once at order time. Against BGA 1449 for 12 W to 28 W UP3 parts, BGA 1598 is the smaller low power option with the same graphics architecture in a reduced thermal envelope.
Processor generations
| Codename | Marketing name | Years | Notes |
|---|---|---|---|
| Tiger Lake-U | 11th Gen Core UP4 series | 2021 | Low power 4-core Willow Cove processors with Iris Xe graphics for thin and light designs, launched in the first quarter of 2021 with 7 W to 15 W configurables. |
Who BGA 1598 serves
BGA 1598 serves thin and light laptops where board area and battery life shape every choice. The UP4 die drops the configurable power to 7 W at the low end and 15 W at the high end, which lets makers use a smaller mainboard and a slimmer cooler than the UP3 stack. The trade is a lower sustained clock than larger packages, while single thread bursts stay close for web work and office tasks.
The Core i7-1180G7 shows the balance. It keeps 4 cores with 8 threads and 96 execution units of Iris Xe graphics, with graphics boost to 1.10 GHz. The CPU base of 2.2 GHz at 15 W can drop to 900 MHz at 7 W for fanless moments, then rise to 4.6 GHz for short tasks. That range suits travel laptops, small convertibles and compact business machines that move between meetings.
Memory, PCIe and thermals
Memory on BGA 1598 is LPDDR4x up to 4267 MT/s in two channels, with a board limit of 32 GB on the lead processor. The soldered memory sits near the die, which helps power use in sleep and idle. Buyers should order the needed capacity at purchase, since later expansion is not possible.
PCIe from the CPU is Gen4, paired with Thunderbolt 4 through the board for docks, storage and external displays. The integrated Iris Xe graphics drive the internal panel and up to four displays through the board outputs. For cooler guidance, the CPU cooler compatibility by socket guide explains why soldered packages list no mounting pattern and how laptop cooling differs from desktop towers.

Frequently asked questions
What is BGA 1598?
BGA 1598 is a soldered ball grid array with 1598 balls. The processor solders to the laptop board and cannot be replaced.
Which processors use BGA 1598?
Tiger Lake-UP4 processors such as the Intel Core i7-1180G7. They have 4 cores with 8 threads and Iris Xe graphics in a 7 W to 15 W envelope.
Can I upgrade a BGA 1598 processor?
No. The chip solders to the board, so the only path is a board or system replacement. Order memory and performance at purchase time.
What memory does BGA 1598 support?
LPDDR4x up to 4267 MT/s in two channels, up to 32 GB on the lead processor. The memory solders near the die and cannot be expanded later.
How does BGA 1598 differ from BGA 1449?
BGA 1598 covers 7 W to 15 W UP4 designs, while BGA 1449 covers 12 W to 28 W UP3 and H35 designs with a larger package and higher sustained clocks.
