Intel Core i5-1035G1 vs Intel Core i5-1035G4
Intel Core i5-1035G1► remove from comparison
The Intel Core i5-1035G1 is a quad-core SoC of the Ice Lake product family. It was announced in May 2019 and it features Hyper-Threading-enabled Sunny Cove CPU cores running at 1 GHz to 3.6 GHz. The highest Boost clock speed achievable when under all-core load is 3.2 GHz.
This Core i5 is designed for use in ultra-light laptops and Windows tablets. Unlike the costlier Core i5-1035G4, this i5 has the 32 EU UHD Graphics G1 iGPU, not the 48 EU Iris Plus G4; 1035G1's CPU cores run at a slightly lower clock rate, too.
Ice Lake processors bring a significant, double-digit per-MHz performance boost over their immediate predecessors, much like Intel promised. What Intel was less keen on highlighting was the significant dip in clock speeds; Core i5-1035G1, Core i7-1065G7 and other Ice Lake CPUs run at lower clock speeds than similarly-specced Comet Lake or Whiskey Lake processors do when under the same load conditions.
Core i5-1035G1 is capable of HW-accelerating certain AI workloads. Thunderbolt and Wi-Fi 6 support is partially baked in the chip. The integrated RAM controller is compatible with up to 64 GB of DDR4-3200 or LPDDR4-3733 memory.
The i5 has several PCI-Express 3.0 lanes for connecting discrete graphics cards, SSDs and other devices. Four PCI-Express 3.0 lanes allow for read/write rates of up to 3.9 GB/s provided a suitably fast NVMe SSD is used.
Please note this is not a user-replaceable CPU. It is supposed to get soldered permanently on to the motherboard (BGA1526 socket interface).
In the grand scheme of things, Core i5-1035G1 is a lower mid-range CPU. It is good for more than just the basic tasks while being no match for true high-performers such as the mighty Core i7-10850H.
The i5's multi-core performance puts it in the same league as Ryzen 5 2500U, Core i5-8259U, Core i5-10210U. Your mileage may vary depending on how competent the cooling solution of a system is and how high the Power Limits are.
UHD Graphics G1 is based on Intel's 11th gen architecture. The UHD Graphics runs at 300 MHz to 1,050 MHz and has 32 EUs; Iris Plus G4 has 48 EUs while Iris Plus G7 has 64 EUs, for reference. This iGPU will let you use up to 3 monitors simultaneously in resolutions up to 5120 by 3200.
UHD Graphics G1 is significantly faster than the UHD Graphics 620, yet it's still not as good as a proper discrete graphics card. It will let you play a moderately long list of games, F1 2020 included, provided you are OK with 720p resolution and Lowest quality preset.
The Core i5 is manufactured on Intel's first-gen 10 nm process for moderately good energy efficiency.
Core i5-1035G1 has a default TDP (also known as the long-term Power Limit) of 15 W that can be set to as high as 25 W by an OEM if required. The CPU is designed for use in ultra-portable laptops, Windows tablets and mini-PCs. Long-term performance sustainability will be rather poor in passively cooled setups.

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).
