Intel Core i5-1035G1
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 four Hyper-Threading-enabled Sunny Cove 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 (yet actively cooled) 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.
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 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. Intel claims this process to be nearly as good as TSMC's 7 nm process.
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-PC. Long-term performance sustainability will be rather poor in passively cooled setups.
