Intel Core i7-1185G7 vs Intel Core i5-1135G7
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 an energy-efficient quad-core SoC designed for the sleeker laptops. The Tiger Lake-UP3 processor was introduced in September 2020. It has four Willow Cove processor 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 frequency is 3.8 GHz. The CPU supports thread-doubling Hyper-Threading, allowing for up to 8 concurrent processing threads.
A sizeable performance-per-MHz boost is one of the multiple improvements of Tiger Lake compared to the older Comet Lake and Ice Lake product families. A Core i5-1135G7 is compatible with dual-channel DDR4-3200 or LPDDR4x-4267 RAM, supports PCI-Express 4.0 (4 lanes) and is able to HW-accelerate AI workloads. Thunderbolt 4, USB 4 and Wi-Fi 6 support is partially baked into the chip. The i5 CPU is manufactured on the second-gen 10 nm Intel SuperFin process that should be comparable to the 7 nm TSMC process Ryzen 4000 processors are manufactured on. Both the CPU cores and the iGPU have access to 8 MB of L3 cache. The faster Core i7-11X5 parts are notable for their larger Level 3 cache size (12 MB versus 8 MB) and higher clock speeds. The i5 gets soldered straight to the motherboard (BGA1449 socket) and is extremely hard to replace.
The Boost sustainability depends a lot on the cooling system performance as well as the TDP settings. With that in mind, the average Core i5-1135G7 from our database is just as fast as the Core i5-10400H, Core i5-8300H, and Ryzen 7 3700U in multi-core benchmarks. The single-core performance is a lot better though, 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 nicer side. The CPU will have no difficulty coping with some light gaming and video editing on the go, and the simpler tasks such as web browsing and spreadsheet editing will pose no problem for it, either.
The Iris Xe Graphics G7 iGPU is based on the brand-new Gen 12 architecture. It is somewhat faster than the older Iris Plus G7 (Ice Lake) and much faster than the UHD 620 (Comet Lake). In the case of the Core i5, the Xe GPU uses 80 of the 96 EUs clocked at 400 MHz to 1,300 MHz. The Iris Xe G7 (80 EUs) can drive up to 4 monitors in resolutions up to SUHD 4320p, and the built-in video decoder can handle the AVC, HEVC, VP9 and last but not the least AV1 video streams. The gaming performance is comparable to entry-level discrete graphics cards such as the Nvidia GeForce MX250.
The 10 nm manufacturing process and low core count render the Tiger Lake-U processors relatively energy-efficient. The TGL-UP3 CPUs' default TDP value is in the range of 12 W to 28 W (the OEMs get to set the value according to their needs) to make the i5 a good fit for the thinner, lighter laptops as well as the occasional high-end tablet. Long-term performance sustainability is likely to be an issue in passively-cooled setups.
