What the Core i5-1035G1 is
The Core i5-1035G1 is a four core, eight thread Ice Lake-U processor for mainstream thin laptops. It launched in August 2019 with a 1.0 GHz base and up to 3.6 GHz boost at 15 W. It matches the 1035G4 CPU with standard UHD graphics instead of Iris Plus.
Six megabytes of Smart Cache back office multitasking across eight threads. The low base stretches battery while boost lifts document loads. Configurable TDP from 13 to 25 W spans silent ultrabooks and performance thin designs.
UHD Graphics up to 1.05 GHz cover displays and 4K video without gaming ambitions. The G1 suffix suits buyers who need Ice Lake CPU with basic graphics. Four cores keep background tasks smooth.
Socket and motherboard compatibility
The 1035G1 solders to BGA 1526 permanently. Laptop makers tune cTDP per chassis. There is no socketed alternative.
Memory choices span SODIMM DDR4 and soldered LPDDR4 across designs. Business lines add vPro capable firmware on some SKUs. The How to find your CPU socket type guide shows where maker specs list the package.
BGA 1377 Y boards cannot take this 15 W chip. Power envelopes differ.
Memory, PCIe and cooling
DDR4-3200 or LPDDR4-3733 in two channels up to 64 GB is the thin laptop memory. Office builds ship 8 GB with room to 16 GB. Dual channel mode helps graphics.
PCIe 3.0 lanes wire NVMe storage and board devices. A 512 GB NVMe SSD is the typical pairing. Thunderbolt 3 on premium bodies adds docks.
Single fan cooling covers 15 W quietly. Sustained loads settle near base in slim bodies. No retail cooler pattern exists.
Upgrade paths
Soldered BGA blocks processor upgrades. Memory to 16 GB and a larger SSD extend office life. Battery service restores travel use.
A laptop change to the Core i5-1035G4 adds Iris Plus graphics on the same BGA 1526 family. Newer generations raise efficiency for refresh years.
