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
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 i5-1135G7► remove from comparison
The Intel Core i5-1135G7 is a quad-core, mid-range SoC designed to be used in ultra-light laptops. The Tiger Lake-UP3 processor was introduced in September 2020. It features four Willow Cove CPU cores running at 2.4 GHz (base clock speed @ 28 W TDP) Boosting up to 4.2 GHz (1-core Boost). The all-core Boost clock speed sits at 3.8 GHz. This is a Hyper-Threading-enabled CPU, allowing for up to 8 concurrent processing threads.
A sizeable performance-per-MHz boost is one of the multiple strengths of Tiger Lake compared to the older Ice Lake and Comet Lake product families. Core i5-1135G7 is compatible with dual-channel DDR4-3200 or quad-channel LPDDR4x-4267 RAM, supports PCI-Express 4.0 (4 lanes) and is capable of HW-accelerating AI workloads. Thunderbolt 4, USB 4 and Wi-Fi 6 support is partially baked into the chip. Four PCI-Express 4.0 lanes allow for read/write rates of up to 7.9 GB/s, provided a suitably fast NVMe SSD is used.
The i5 is manufactured on Intel's second-gen 10 nm process marketed as SuperFin that is supposedly comparable to TSMC's 7 nm process that Ryzen 4000 series laptop-grade processors are manufactured on. Both the CPU cores and the iGPU enjoy access to 8 MB of L3 cache. The higher-end Core i7-11x5 parts are notable for their larger Level 3 cache (12 MB versus 8 MB), faster iGPUs and higher clock speeds. Core i5-1135G7 is supposed to be permanently soldered to the motherboard (BGA1449 socket interface) and is thus not user-replaceable.
The i5's long-term Boost sustainability will depend heavily on how high the Power Limits and how good the cooling solution of a laptop are. That being said, the average Core i5-1135G7 in our database is just as fast as the Core i5-10400H, Core i5-8300H, and Ryzen 7 3700U in multi-core benchmarks. The CPU acts even nicer when under single-core load, reaching similar heights as the Ryzen 7 5600X and Core i7-8700K. The performance may not be ground-breaking, but it’s still on the sunnier side. This Core i5 will have no difficulty coping with some light gaming and video editing on the go, and the more mundane tasks including the usual web browsing and spreadsheet editing will pose no problem, either.
The 80 EU Iris Xe Graphics G7 is based on Intel's Gen 12 architecture. The iGPU is somewhat faster than the older Iris Plus G7 (Ice Lake) and much faster than the UHD 620 (Comet Lake). The 80 EUs are clocked at 400 MHz to 1,300 MHz. This graphics adapter can drive up to 4 monitors in resolutions up to SUHD [email protected] and hardware decode the AVC, HEVC, VP9 and last but not the least AV1 video streams. The iGPU's gaming performance is close to what a typical GeForce MX250 has in store; casual gamers will be happy with the Xe as it will easily handle most titles at 720p on low or medium quality settings. An important thing to keep in mind is that the iGPU has no video memory of its own, making fast RAM a necessity.
The Core i5's 10 nm manufacturing process and low core count render it relatively energy-efficient. Just like all other Tiger Lake-UP3 processors, Core i5-1135G7 has a long-term Power Limit of 12 W to 28 W (OEMs get to set the value according to their needs). This makes the i5 a good fit for thinner, lighter systems as well as an occasional Windows tablet. The CPU's long-term performance sustainability is likely to be very poor in passively cooled setups.
