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.
Performance
The average 1185G7 in our database is just as fast as AMD's hexa-core Ryzen 5 4500U, as far as multi-thread benchmark scores are concerned. While the i7 is not the fastest Tiger Lake chip by any stretch of imagination, it's more than usable for your productivity and creative apps, with a bit of gaming possible as well.
Thanks to its decent cooling solution and a long-term CPU power limit of 55 W, the Stealth 15M A11SEK is among the fastest laptops powered by the 1185G7 that we know of. It can be almost twice as fast in CPU-bound workloads as the slowest system featuring the same chip in our database, as of August 2023.
Power consumption
This little Core i7 here has a default TDP of 12 W to 28 W, the expectation being that laptop manufacturers will go for a higher value in exchange for higher performance. Either way, that's a tad too high to allow for passively cooled designs.
The chip is manufactured on Intel's third-gen 10 nm process marketed as SuperFin for average, as of late 2022, energy efficiency.
The Intel Core Ultra 5 125H is a mid-range Meteor Lake family chip that debuted in December 2023. This 1st Gen Core Ultra processor has come to replace 13th generation Core chips; it has 14 cores (4 + 8 + 2) and 18 threads at its disposal. Its Performance cores, of which there are 4, are HT-enabled and run at up to 4.5 GHz while its Efficient cores, of which there are 10 (8 main cores plus 2 extra ones found in the Low Power Island), run at up to 3.6 GHz. The 7-core Arc GPU, just out of the oven, serves as the integrated graphics adapter - this runs at up to 2.20 GHz - and there is a bevy of other brand-new technologies on offer as well, including the integrated AI Boost NPU with two Gen 3 engines for hardware AI workload acceleration.
Architecture and Features
With Meteor Lake, Intel intends to deliver higher CPU performance, higher GPU performance and at the same time, longer battery life than what Raptor Lake chips were capable of. The company also wants a large piece of the AI cake and is working with Microsoft and other partners to make that happen. As a result, Windows Defender is now AI-enabled, meaning it can use the Intel NPU to take some of the load off the main CPU cores. We also get this new Intel Device Discovery technology that is designed to give us a better hardware-based remote laptop management than ever before; and, to make things even better, Intel now offers a dedicated Arc Pro graphics driver for workstations.
This generation of Intel Core processors features Redwood architecture P-cores and Crestwood architecture E-cores. Both come with slight architectural improvements over Raptor Cove and Gracemont respectively for slightly higher performance-per-clock figures; the interesting thing is that of the 10 E-cores, two are actually a separate cluster located on what Intel calls a "Low Power Island". Essentially, the latter is an SoC within an SoC that can stay active while most other parts of the chip are temporarily switched off to save power. The low-power E-cores run at up to 2.5 GHz. Intel hopes this approach will let it deliver unprecedentedly low power consumption figures when under low load, boosting battery life of laptops and tablets powered by Meteor Lake.
To build its Meteor Lake processors, Intel uses the Foveros technology (stacking several chips on top of each other). This is a cost-cutting measure more than anything else, as manufacturing several small dies on several different processes is so much cheaper than making a huge single die and hoping that there are no defects in it that will require disabling some parts of it.
Elsewhere, the Core Ultra 5 125H comes with 18 MB of L3 cache which is a significant reduction compared to the 24 MB that the 155H, the 165H and the 185H have. The processor has a very healthy number of PCIe 5 and PCIe 4 lanes for NVMe SSD speeds up to 15.7 GB/s; it supports RAM running at up to 7467 MHz (DDR5-5600, LPDDR5-7467, LPDDR5x-7467, to be specific - which is about as good as what 8040 series Ryzen chips have). Naturally, the 125H features built-in Thunderbolt 4 support and Intel CNVi Wi-Fi support. It is also worth mentioning that Intel chose to keep native SATA III support that AMD had removed from its Ryzen processors quite a while ago.
The 125H is compatible with 64-bit Windows 10, 64-bit Windows 11 and with many Linux distros.
Performance
While we have no way of knowing what the 125H will be like, as of December 2023, it's safe to expect the chip to be slightly slower than the Ryzen 7 7735HS (Zen 3 Plus, 8 cores, 16 threads, up to 4.75 GHz), as far as multi-thread performance is concerned.
Either way, real-world performance of the chip may vary significantly depending on how high the CPU power limits are and how competent the cooling solution of the system is.
Graphics
The 7-core Arc GPU running at up to 2.20 GHz is set to overshadow the Radeon 760M; just like the 8-core Arc GPU, this graphics adapter is set to be miles ahead of the aging Xe-series integrated GPUs. As long as one chooses to take Intel's word for it, that is.
A proper DX12 Ultimate graphics adapter, the Arc is no stranger to ray tracing and other modern technologies including AI frame generation (XeSS). It will let you connect up to four SUHD 4320p monitors and it will both HW-encode and HW-encode the most widely used video codecs including AVC, HEVC and AV1 in a fast and efficient manner.
Your mileage may vary depending on how high the CPU power limits are, how competent the cooling solution of your system is, how fast the RAM of your system is. The latter is really important; Intel stresses that for the Arc to deliver the best results possible, multi-channel RAM configuration is a must.
Power consumption
The Base power consumption, in the case of the 125H, is 28 W while its maximum Turbo power consumption is supposed to be within 115 W. A powerful cooling solution is a must for any system powered by this chip.
This Core Ultra 5 series processor is comprised of five small chips ("tiles") that are connected using Intel's Foveros technology. The tile containing main CPU cores is produced on the fairly modern 7 nm Intel process marketed as Intel 4 while most other tiles (the iGPU, the I/O die, ...) are built with TSMC's N5 and N6 processes. The base tile is built with the old Intel 22FFL process.
