Intel Core i7-1165G7 vs Intel Core i7-1255U

Intel Core i7-1165G7

► remove from comparison Intel 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.

Intel Core i7-1255U

► remove from comparison Intel i7-1255U

The Intel Core i7-1255U is a high-end mobile CPU for thin and light laptops based on the Alder Lake architecture. It was announced in early 2022 and offers 2  performance cores (P-cores, Golden Cove architecture) and 8 efficient cores (E-cores, Gracemont architecture). The P-cores support Hyper-Threading leading to 12 supported threads when combined with the E-cores. The clock rate ranges from 1.7 to 4.7 GHz on the performance cluster and 1.2 to 3.5 GHz on the efficient cluster. The performance of the E-cores should be similar to old Skylake cores (compare to the Core i7-6700HQ). All cores can use up to 12 MB L3 cache. Compared to the i7-1265U (fastest U-series CPU at launch), the 1255 offers 100 MHz lower clocked CPU cores and only "Essentials" vPro management features. Compared to the P-series (28W) or H-series (45W), the 15W TDP may limit the sustained performance.

Performance

The average 1255U in our database is in the same league as the Ryzen 5 5600U, as far as multi-thread benchmark scores are concerned. Which is nothing to be ashamed of, as of mid 2023.

Thanks to its decent cooling solution and a long-term CPU power limit of 28 W, the Spectre x360 13.5 14t-ef000 is among the fastest laptops built around the 1255U that we know of. It can be 20% faster in CPU-bound workloads than the slowest system featuring the same chip in our database, as of August 2023.

Architecture

The integrated memory controller supports various memory types up to DDR5-4800, DDR4-3200, LPDDR5-5200, and LPDDR4x-4267. The Thread Director (in hardware) can support the operating system to decide which thread to use on the performance or efficient cores for the best performance. For AI tasks, the CPU also integrates GNA 3.0 and DL Boost (via AVX2). Quick Sync in version 8 is the same as in the Rocket Lake CPUs and supports MPEG-2, AVC, VC-1 decode, JPEG, VP8 decode, VP9, HEVC, and AV1 decode in hardware. The CPU only supports PCIe 4.0 (x8 for a GPU and two x4 for SSDs).

The integrated graphics card is based on the Xe-architecture and offers all 96 EUs (Execution Units) operating at up to 1.25 GHz.

Power consumption

This Core i7 has a "minimum assured" power consumption of 12 W. Its Base power consumption sits at 15 W and its maximum Intel-recommended Turbo power consumption isn't supposed to exceed 55 W. All those values are too high to allow for pasisvely cooled designs.

Last but not the least, Core i7-1255U is built with Intel's fourth-gen 10 nm process marketed as Intel 7 for decent, as of late 2022, energy efficiency.
