The Intel Core i5-1035G4 is a power efficient quad-core SoC for laptops and Ultrabooks based on the Ice -Lake-U generation that was announced in Mai 2019 (Computex). It integrates four Sunnycove processor cores (8 threads thanks to HyperThreading) clocked at 1.1 (base) - 3.7 (single core Turbo) GHz. 2 cores can reach 3.6 GHz and all four 3.3 GHz using Turbo Boost. According to Intel the Sunnycove cores achieve 18% more IPCs (Instructions per Clock) and therefore the CPU performance should be similar to the higher clocked Whiskey-Lake predecessors (e.g. Core i5-8365U with up to 4.1 GHz).
Compared to the similar called Core i5-1035G7, the G4 variant uses a slower GPU and offers 100 MHz less base clock. Therefore, the CPU speed should be quite similar to the second fastest Ice Lake-U CPU, the Core i5-1035G7.
The biggest improvement for Ice-Lake is the integrated Gen 11 graphics card called Iris Plus Graphics. The Core i7-1065G4 integrates the smaller G4 variant with 48 of the 64 CUs clocked at 300 - 1050 MHz.
Other improvements for Ice Lake are the AI hardware acceleration and the partial integration of Thunderbolt and Wifi 6 in the chip. The integrated DDR4 memory controller supports modules with up to 3200 MHz (and LPDDDR4 3733).
The Core i5-1035G4 is produced in the new 10nm process at Intel (2nd generation) that should offer a comparable performance to the 7nm process at TSMC. The TDP is specified at 15 Watts and therefore the CPU can be used in thin and light laptops (but usually with a fan). Intel offers a configurable TDP of 7.5 - 25 Watts for the partners resulting in significant performance differences (due to longer periods of Turbo Boost).
