Intel Core i5-1135G7 vs Intel Core i5-1155G7

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. Higher-end Core i7-11x5 processors 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 your laptop are. That being said, the average Core i5-1135G7 in our database is just as fast as Intel Core i7-10810U, Core i5-1145G7, Core i5-1230U and AMD Ryzen 7 3780U are in multi-thread benchmarks. 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 usual web browsing and spreadsheet editing will pose no problem to it, 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 10 nm manufacturing process and low core count render this Core i5 a relatively energy-efficient CPU. 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.

The Intel Core i5-1155G7 is a power efficient quad-core SoC for laptops and Ultrabooks based on the Tiger Lake-U generation that was announced in mid 2021 as part of the refresh. 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 GHz (12 Watt TDP) up to 2.5 GHz (28 Watt). Boost clock speed is 4.5 GHz.
The average 1155G7 in our database proves to be a very decent mid-range processor, trading blows with Intel Core i7-10810U and AMD Ryzen 5 4500U as far as multi-thread load is concerned. While perhaps not the best option for power users, this Core i5 will make most consumers happy, providing for short load times and generally pain-free experience.
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.
The chip is produced on the improved 10nm SuperFin process at Intel that should be comparable to the 7nm process at TSMC (e.g. Ryzen 4000 series).
Another novelty is the integrated Xe graphics adapter 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).
