Intel Core i3-1005G1 vs Intel Core i5-1135G7 vs Intel Core i7-1165G7

Intel Core i3-1005G1

The Intel Core i3-1005G1 is a low-power, Ice Lake family processor (SoC) featuring 2 cores, 4 threads, 4 MB of L3 cache and the UHD G1 (32 EUs) iGPU. It saw the light of day in 2019. The chip is designed for use in highly portable laptops of the more affordable flavour; the CPU cores run at 1.2 GHz to 3.4 GHz which is not a lot.

Architecture & Features

Ice Lake family chips are powered by Sunny Cove CPU cores.The latter aim to do what Palm Cove cores (that we never really got a chance to get a taste of) were expected to do, delivering a double-digit IPC uplift over the venerable Skylake architecture thanks to a range of small improvements across the board including scheduler improvements, larger caches and buffers, and support for new instruction sets.

Thunderbolt 3 support is built right into the Core i3 (meaning it has several PCIe 3 lanes exclusive to Thunderbolt devices, reducing the number of additional components required for Thunderbolt to work) and so is Intel CNVi Wi-Fi 6 support (making it easier for Intel to sell its proprietary WLAN cards to laptop makers). The Core i3-1005G1 also has the DL Boost and GNA features for applications centered around machine learning.

The 4 GT/s bus is indicative of a consumer-grade chip, since CPUs for gaming laptops and portable workstations usually employ the faster 8 GT/s bus. RAM support is nothing to sneeze at, at up to DDR4-3200 or LPDDR4-3733. NVMe SSDs are supported, with data transfer rates limited to 3.9 GB/s (this is what four PCIe 3 lanes are good for). SATA drives and even eMMC chips are also natively supported here.

This is not a user-replaceable CPU, as it gets permanently soldered to the motherboard (BGA1526 socket interface).

OS support is limited to 64-bit Windows 10 and 64-bit Windows 11, as well as many Linux distros.

Performance

The average 1005G1 in our database is a disappointment, its multi-thread benchmark scores only matching those of Intel's Core i5-7267U and AMD's Ryzen 3 2300U. This is unfortunately in line with what we've been seeing from other Ice Lake family processors; they tend to be held back by their comparatively low clock speeds. While not as slow as many Celerons and Pentiums, this Core i3 will still look out of place in anything but the most affordable laptops and mini-PCs.

With its long-term CPU power limit of 25 W, the Lenovo V17-IIL 82GX008TGE is among the fastest laptops built around this Core i3 that we know of.

Graphics

The Core i3-1005G1 features the UHD Graphics G1 (32 EUs) graphics adapter running at up to 900 MHz. This DX12-compatible iGPU is not much faster than the dated UHD 620 graphics solution, making it almost useless to gamers, and there are no cutting-edge features such as ray tracing support to be found here, either. The list of supported resolutions tops out at 5120 x 3200, and there is no hardware AV1 codec support meaning such a video will be SW-decoded with rather low energy efficiency. The usual HEVC, AVC and VP9 options are supported, thankfully.

The G1 will drive up to 3 monitors simultaneously, provided the system has the outputs required. Higher-end Ice Lake chips are equipped with the G4 (48 EUs) or the G7 (64 EUs) adapters that are significantly faster.

Power consumption

The Core i3 has a 15 W default TDP (also known as the long-term power limit), a value that laptop makers are allowed to reduce slightly - 13 W being the lower limit - resulting in lower clock speeds and lower performance. Either way, that's a tad too high to allow for passively cooled designs.

The SoC is built with Intel's second-gen 10 nm process (not "10 nm SuperFin" or "Intel 7") for average, as of late 2022, energy efficiency.

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 i7-1165G7

The Intel Core i7-1165G7 is an upper mid-range, quad-core SoC designed for use in ultra-thin laptops. The Tiger Lake-UP3 processor was unveiled in September 2020; its Hyper-Threading-enabled Willow Cove CPU cores run at 2.8 GHz (base clock speed @ 28 W TDP) to 4.7 GHz (single-core Boost frequency). The all-core Boost frequency sits at 4.1 GHz. This i7 was the second-fastest CPU of TGL-UP3 line-up when Intel initially launched the series in 2020.

The i7 is ever-so-slightly inferior to Intel Core i7-1185G7 in that vPro support is nowhere to be found, the clock speeds are lower, and the iGPU's clock speed is a little lower as well.

Architecture

A sizeable performance-per-MHz boost is one of the many benefits of Tiger Lake generation compared to the older Ice Lake and Comet Lake product families. Core i7-1165G7 is compatible with dual-channel DDR4-3200 or quad-channel LPDDR4x-4267 RAM; Intel recommends using no more than 64 GB, for reference. The processor also supports PCI-Express 4.0 (4 lanes) and is capable of HW-accelerating certain 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 i7 is built with the third-gen 10 nm Intel process marketed as SuperFin that is supposedly comparable to TSMC's 7 nm process, the one Ryzen 4000 and Ryzen 5000 series processors are manufactured on. Both the CPU cores and the iGPU have access to 12 MB of L3 cache. The SoC is supposed to be soldered straight on to the motherboard (BGA1449 socket interface); it is thus anything but user-replaceable.

Performance

The average i7-1165G7 in our database is just as fast as Intel's Core i5-10200H and Core i7-10810U are, as far as multi-thread benchmark scores are concerned. The chip is brave enough to come dangerously close to the noticeably costlier i7-1195G7 while unfortunately not quite reaching the high bar set by the Ryzen 3 5300U. That being said, it's a very decent CPU that will have no trouble chewing through light video editing and 3D rendering jobs on the go with a bit of gaming possible as well, as of early 2022.

Thanks to its decent cooling solution and a long-term CPU power limit of 40 W, the Schenker Vision 15 is among the fastest laptops built around the 1165G7 that we know of. It can be more than 60% faster in CPU-bound workloads than the slowest system featuring the same chip in our database, as of August 2023.

Graphics

The Iris Xe Graphics G7 (96 EUs) is based on Intel's Generation 12 architecture. It is a lot faster than the older Iris Plus G7 (Ice Lake) and UHD Graphics 620 (Comet Lake) solutions. The Xe has 96 Execution Units running at 400 MHz to 1,300 MHz, in the case of this Core i7.

This graphics adapter can drive up to 4 monitors in resolutions as high as SUHD 4320p@60 simultaneously, and the built-in video decoder is AV1-friendly. It will happily decode most other video codecs including HEVC, AVC, VP9, MPEG-2 and so on, too.

The Xe will let you play most games at 1080p / Low. It's nearly as fast as NVIDIA's GeForce MX350, surpassing anything we have seen from AMD's integrated graphics thus far. It is paramount that fast RAM is used as the Xe has no VRAM of its own. The other prerequisites for decent 3D performance are decently high Power Limits and a competent cooling solution.

Power consumption

The i7-1165G7 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 too high to allow for passively cooled designs.

The i7 is built with Intel's third-generation 10 nm process marketed as SuperFin for decent, as of mid 2022, energy efficiency.
