Intel Core i5-1034G1 vs Intel Core i7-1065G7 vs Intel Core i3-1005G1

Intel Core i5-1034G1

The Intel Core i5-1034G1 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 0.8 (base) - 3.6 (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).

The biggest improvement for Ice-Lake is the integrated Gen 11 graphics card called UHD Graphics G1. The Core i5-1034G1 integrates the smallest GPU, the UHD Graphics that features 32 of the 64 CUs and clocks at 300 - 1050? MHz. The faster variants include Iris Plus G4 and G7.

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 i5-1034G1 is produced in the improved 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).

Intel Core i7-1065G7

The Intel Core i7-1065G7 is a power efficient quad-core SoC of the Ice Lake U product family designed for thin laptops and Ultrabooks. It was announced in May 2019 (Computex). The CPU has four Sunnycove processor cores (8 threads thanks to Hyper-Threading) clocked at 1.3 (base) - 3.9 (single core Turbo) GHz. 2 cores can reach 3.8 GHz and all four 3.5 GHz using Turbo Boost. According to Intel the Sunnycove cores achieve 18% more IPCs (Instructions per Clock).

Other improvements for Ice Lake are the AI hardware acceleration and the partial integration of Thunderbolt and Wi-Fi 6 in the chip. The integrated DDR4 memory controller supports modules with up to 3200 MHz (and LPDDDR4 3733).

The biggest improvement of Ice Lake is the integrated Gen 11 graphics adapter called Iris Plus Graphics. The Core i7-1065G7 integrates the biggest G7 variant with 64 EUs clocked at 300 - 1100 MHz. The Iris Plus G7 should be twice as fast as the predecessors and best the AMD Vega 10 GPU from current Ryzen APUs.

Performance

The average 1065G7 in our database is most comparable to AMD Ryzen 7 2700U and Intel Core i5-8259U, as far as multi-thread performance is concerned. This is a so-so result and a direct consequence of Intel's inability to make the best of its brand-new 10 nm node. Intel Core i7-10710U, a 10th gen processor built with an older 14 nm process, will easily rip a 1065G7 to pieces. That said, a 1065G7 will beat a 10710U in terms of energy efficiency.

Power consumption

This Core i7 has a default TDP, also known as the long-term power limit, of 15 W. Laptop manufacturers are free to change that value to anything between 12 W and 25 W with clock speeds and performance changing accordingly as a result. Either way, that's a tad too high to allow for passively cooled designs.

The quad-core Intel CPU is built with Intel's first-gen 10 nm process for average, as of early 2023, energy efficiency.

Intel Core i3-1005G1

The Intel Core i3-1005G1 is a power efficient dual-core SoC for laptops and Ultrabooks based on the Ice Lake-U generation that was announced in Mai 2019 (Computex). It integrates two Sunnycove processor cores (4 threads thanks to HyperThreading) clocked at 1.2 (base) - 3.4 GHz (single and dual core Turbo). According to Intel the Sunnycove cores achieve 18% more IPCs (Instructions per Clock).

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).

Performance

The average 1005G1 in our database is a disappointment, its multi-thread benchmark scores only matching those of Intel Core i5-7267U and AMD Ryzen 3 2300U. This is unfortunately in line with what we've been seeing from most other Ice Lake family processors. While not as slow as an Intel Celeron, a Core i3-1005G1 will still look out of place in anything but entry-level laptops and mini-PCs.

The biggest improvement for Ice-Lake is the integrated Gen 11 graphics processor called UHD Graphics G1. The Core i3-1005G1 integrates the smallest GPU, the UHD Graphics with 32 of the 64 EUs clocked at 300 - 900 MHz. The higher-end Iris Plus G4 and G7 offer higher clock speeds (up to 1100 MHz) and up to 64 EUs.

Power consumption

The Core i3 has a 15 W default TDP (also known as the long-term power limit), a value that laptop manufacturers are allowed to reduce slightly - 13 W being the lower limit - resulting in lower clock speeds and lower performance. Either way, that's a tad too high to allow for passively cooled designs.

The dual-core Intel CPU is built with Intel's first-gen 10 nm process for average, as of late 2022, energy efficiency.
