Intel Core i7-1065G7 vs Intel Core i9-12900H vs Intel Core i5-1035G7

Intel Core i7-1065G7

► remove from comparison

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 the AMD Ryzen 7 2700U and the Intel Core i5-8259U, as far as multi-thread benchmark scores are 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. The Core i7-10710U, a 10th generation processor built with an older 14 nm process, will easily rip a 1065G7 to pieces. That said, the 1065G7 will surely beat a 10710U in terms of energy efficiency.

Thanks to its decent cooling solution and sufficiently high CPU power limits, the Galaxy Book Flex 15-NP950 is among the fastest laptops powered by the 1065G7 that we know of. It can be around 40% faster in CPU-bound workloads than the slowest system featuring the same chip in our database, as of August 2023.

Power consumption

This Core i7 has a default TDP, also known as the long-term power limit, of 15 W. Laptop makers 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 second-gen 10 nm process (not 10 nm SuperFin or Intel 7) for average, as of late 2022, energy efficiency.

Intel Core i9-12900H

► remove from comparison

The Intel Core i9-12900H is a high-end mobile CPU for laptops based on the Alder Lake architecture. It was announced in early 2022 and offers 6 performance cores (P-cores, Golden Cove architecture) and 8 efficient cores (E-cores, Gracemont architecture). The P-cores support Hyper-Threading leading to 20 supported threads when combined with the E-cores. The clock rate ranges from 2.5 to 5 GHz on the performance cluster and 1.8 to 3.8 GHz on the efficient cluster. The performance of the E-cores should be similar to old Skylake cores (compare to the Core i7-6920HQ). All cores can use up to 24 MB L3 cache. Compared to the 12900HK, the 12900H does not offer the open multiplicator (for overclocking) but the full "Enterprise" set of vPro features (for remote management).

The integrated memory controller supports various memory types up to DDR5-4800, DDR4-3200, LPDDR5-5200, and LPDDR4x-4267. The Thread Director (in hardware) can support the operating system to decide which thread to use on the performance or efficient cores for the best performance. For AI tasks, the CPU also integrates GNA 3.0 and DL Boost (via AVX2). Quick Sync in version 8 is the same as in the Rocket Lake CPUs and supports MPEG-2, AVC, VC-1 decode, JPEG, VP8 decode, VP9, HEVC, and AV1 decode in hardware. The CPU only supports PCIe 4.0 (x8 for a GPU and two x4 for SSDs).

The integrated graphics card is based on the Xe-architecture and offers 96 EUs (Execution Units) operating at up to 1.45 GHz.

Performance

The average 12900H in our database proves to be an outrageously fast CPU, ripping the Ryzen 9 6900HX to pieces as far as multi-thread benchmark scores are concerned. Perhaps surprisingly, the i9's multi-thread performance is not much higher than that of the Core i7-12700H, suggesting the latter might be a better bang for the buck.

With its decent cooling solution and a long-term Power Limit of 110 W, the Asus StudioBook 16 H7600ZW is one of the fastest laptops built around the i9-12900H that we know of. It can be more than 80% faster than the slowest system featuring the same chip in our database, depending on the circumstances.

Power consumption

The Core i9 has a "minimum assured" power consumption of 35 W, with 45 W being its Base power consumption. The CPU's maximum Intel-recommended Turbo power consumption sits at 115 W.

The i9-12900H is built with Intel's 4th generation 10 nm process marketed as Intel 7 for lower than average, as of mid 2023, energy efficiency.

Intel Core i5-1035G7

► remove from comparison

The Intel Core i5-1035G7 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 1.2 (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). The Core i5-1035G7 is the second fastest Ice Lake-U chip at the time of announcement in 2019.

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

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 1035G7 in our database is in the same league as the Ryzen 3 4300U and the Core i5-10210U, as far as multi-thread benchmark scores are concerned. Which isn't bad at all as of late 2021. The Core i5-1035G4 and the Core i5-1035G1 are two other chips that nearly match the 1035G7 in multi-thread performance.

Thanks to its decent cooling solution and a long-term CPU power limit of 22 W, the Surface Laptop 3 13 is among the fastest laptops built around the 1035G7 that we know of. It can be at least 30% faster in CPU-bound workloads than the slowest system featuring the same chip in our database, as of August 2023.

Power consumption

This Core i5 has a default TDP (also known as the long-term power limit) of 15 W, a value that laptop manufacturers are allowed to change to anything between 12 W and 25 W if required with clock speeds and performance changing accordingly. Those values are a little too high to allow for passively cooled designs.

The processor is built with Intel's second-gen 10 nm process for decent, as of late 2022, energy efficiency.
