Intel Core i5-1135G7 vs Intel Core i7-10750H

Intel Core i5-1135G7

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.

Architecture

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 third-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.

Performance

The average i5-1135G7 in our database delivers multi-thread benchmark scores close to those of the Core i7-10810U, Core i5-1145G7, Core i5-1230U and also the Ryzen 7 3780U. 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.

Thanks to its decent cooling solution and a long-term CPU power limit of 25 W, the Lenovo Yoga Slim 7 14ITL05 is among the fastest laptops built around the 1135G7 that we know of. It can be about 60% faster in CPU-bound workloads than the slowest system featuring the same chip in our database, as of August 2023.

Graphics

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 4320p@60 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.

Power consumption

Just like all other Tiger Lake-UP3 chips, the i5-1135G7 has a default TDP of 12 W to 28 W, the expectation being that laptop makers will go for a higher value to get higher clock speeds and thus better performance. Either way, these values are a tad too high to allow for passively cooled designs.

The CPU is built with Intel's 3rd generation 10 nm process marketed as SuperFin for decent, as of mid 2022, energy efficiency.

Intel Core i7-10750H

The Intel Core i7-10750H is a fast 45 W processor designed for use in larger, beefier laptops. The Comet Lake-H family CPU was launched in mid-2020. It features six cores (twelve threads) running at 2.6 GHz Boosting up to 5 GHz (single-core Boost). The likely all-core Boost frequency is 4.3 GHz. Most of the specs are the same as the 10750H’s direct predecessor, the i7-9750H. The newer model has two advantages over its predecessor in that its Boost frequency is higher and the memory controller can now officially host memory clocked at 2,933 MHz, an upgrade over the 2,666 MHz limitation of the outgoing model.

Architecture

Comet Lake is a yet another revision of the dated Skylake architecture (not unlike the previous Coffee Lake, Whiskey Lake, Kaby Lake families) for similar feature set and performance-per-MHz figures. Core i7-10750H is manufactured on the third-gen 14 nm Intel process that is undeniably inferior to TSMC's 7 nm process, the one AMD’s Ryzen 4000 series laptop-grade processors are manufactured on.

The hexa-core CPU is compatible with up to 128 GB of dual-channel DDR4-2933 RAM and has support for PCI-Express 3.0 and Thunderbolt 3 but not the professional features (vPro, TXT, SIPP) as found in the case of Core i7-10850H.

Both the CPU cores and the iGPU have access to 12 MB of L3 cache. Four PCI-Express 3.0 lanes allow for read/write rates of up to 3.9 GB/s provided a suitably fast NVMe SSD is used.

The 10750H gets soldered permanently on to the motherboard (BGA1440 socket interface) and is thus pretty much impossible to replace.

Performance

Multi-thread performance is most similar to the Core i5-10500H, the Core i5-11400H and also the Ryzen 7 4700U. While perhaps not the best bang for the buck, the i7 is fast enough for any task, gaming included, as of late 2021.

Thanks to its decent cooling solution and a long-term CPU power limit of 75 W, the ThinkPad P15 Gen 1-20ST000DGE is among the fastest laptops built around the 10750H that we know of. It can be about 80% faster in CPU-bound workloads than the slowest system featuring the same chip in our database, as of August 2023.

Graphics

We've known the Intel UHD Graphics 630 iGPU for a while. This is the same iGPU the Core i7-9750H and Core i7-8750H processors had. In this i7, the 24 EU iGPU is clocked at 350 MHz to 1,150 MHz.

Intel UHD Graphics 630 will let you connect up to 3 monitors with resolutions of up to 4096x2304@60. The built-in video decoder will happily handle AVC, HEVC, VP9 and other popular video codecs (AV1 is not supported though). This is not a gaming GPU as it is not fast enough to handle most AAA titles released in 2020. At 720p, Escape from Tarkov runs at just 17 fps (low quality preset), to give you an example. As the iGPU has no VRAM of its own, it is paramount that it is mated to fast system RAM.

Power consumption

This Core i7 series chip is built with one of the old 14 nm Intel processes leading to subpar, as of early 2022, energy efficiency.

The Core i7-10750H has a default TDP, also known as the long-term power limit, of 45 W; laptop makers are free to reduce the value somewhat, 35 W being the lower limit, allowing for leaner designs at the cost of performance. Either way, a quality cooling solution is a must.
