Intel Core i5-1145G7 vs Intel Core i7-1185G7 vs Intel Core i3-1125G4

Intel Core i5-1145G7

► remove from comparison Intel i5-1145G7

The Intel Core i5-1145G7 is a power efficient quad-core SoC for laptops and Ultrabooks based on the Tiger Lake-U generation that was announced early 2021. It integrates four Willow Cove processor cores (8 threads thanks to HyperThreading). The base clock speed depends on the TDP settings and ranges from 1.1 GHz (12 Watt TDP) up to 2.6 GHz (28 Watt). The Boost is always specified at 4.4 GHz (one or two cores).

Another novelty is the integrated Xe graphics card with 80 EUs based on the completely new Gen 12 architecture. It offers a significantly higher performance compared to the older Iris Plus G7 (Ice Lake).

Furthermore, Tiger Lake SoCs add PCIe 4 support (4 lanes), AI hardware acceleration, and the partial integration of Thunderbolt 4 / USB 4 and Wifi 6 in the chip. In addition to this, the i5 supports vPro for easy remote management.

The chip is produced in the improved 10nm SuperFin process at Intel that should be comparable to the 7nm process at TSMC (e.g. Ryzen 4000 series).

Intel Core i7-1185G7

► remove from comparison Intel i7-1185G7

The Intel Core i7-1185G7 is a power-efficient quad-core SoC for laptops and Ultrabooks based on the Tiger Lake-U generation (UP3) that was introduced September 2020. It integrates four Willow Cove processor cores (8 threads thanks to Hyper-Threading). Each core can clock from 1.2 GHz (12 W base clock speed), 3 GHz (28 W base clock speed) to 4.8 GHz (single-core boost). All cores at once can clock at up to 4.3 GHz. At the time of announcement, the i7-1185G7 is the fastest model of the line-up. Since early 2021, the i7-1185G7 supports management features like vPro.

Another novelty is the integrated Iris Xe iGPU based on the completely new Gen 12 architecture. It should offer a significantly higher performance compared to the older Iris Plus G7 (Ice Lake). In the i7-1185G7 it uses 96 EUs and clocks between 400 - 1,350 MHz. The GPU and CPU can together use the 12 MB of L3 cache.

Furthermore, Tiger Lake SoCs add PCIe 4 support (four lanes), AI hardware acceleration, and the partial integration of Thunderbolt 4/USB 4 and Wi-Fi 6 in the chip.

The chip is produced on the second-generation 10 nm Intel SuperFin process that is comparable to the 7 nm TSMC process Ryzen 4000 CPUs are manufactured on.

The operating range of the UP3 series is specified at 12 to 28 Watt. Therefore, the processor is suited for thin and light laptops.

Intel Core i3-1125G4

► remove from comparison Intel i3-1125G4

The Intel Core i3-1125G4 is a 28 W quad-core SoC for laptops and Ultrabooks based on the Tiger Lake-U generation (UP3) that was introduced in September 2020. It integrates four Willow Cove processor cores (8 threads thanks to HyperThreading). Each core can clock from 2 GHz (guaranteed base speed @ 28 W) to 3.7 GHz (single-core boost). All cores at once can clock at up to 3.3 GHz. The faster Core i7 models offer more Level 3 cache (12 versus 8 MB in the i5) and higher clocked cores.

Another novelty is the integrated Xe GPU based on the completely new Gen 12 architecture. In the i3-1125G4 Intel names the GPU UHD Graphics and offers only 48 of the 96 EUs clocked at 400 - 1250 MHz. The GPU and CPU can together use the 8 MB of L3 cache.

Furthermore, Tiger Lake SoCs add PCIe 4 support (four lanes), AI hardware acceleration, and the partial integration of Thunderbolt 4 / USB 4 and Wi-Fi 6 in the chip.

The chip is produced on the improved 10nm+ process (called SuperFin) at Intel that should be comparable to the 7nm process at TSMC (e.g. Ryzen 4000 series).

The operating range of the UP3 series is specified at 12 to 28 Watt. Therefore, the processor is also suited for thin and light laptops.
