The Intel Core i7-1260P is an upper mid-range 28 W Alder Lake CPU designed for use in ultra-light laptops. It was announced in early 2022 and it features 4 performance cores as opposed to the 6 cores of the top-of-the-line i7-1280P (P-cores, Golden Cove architecture) mated to 8 efficient cores (E-cores, Gracemont architecture). The P-cores are Hyper-Threading-enabled for a total of 16 threads when combined with the E-cores. The clock speeds range from 2.1 GHz to 4.7 GHz for the performance cluster and 1.5 GHz to 3.4 GHz for the efficient cluster. The i7's shortcomings as compared to Intel Core i7-1270P include the marginally lower clock speeds and limited vPro feature set ("Essentials" tier only, not allowing for remote device management).
Architecture
The i7 is a continuation of Intel's efforts to use the ARM-developed big.LITTLE technology for its own benefit. A single "littile" Alder Lake core is supposed to be just as fast as a Skylake core (as found in the venerable Core i7-6700HQ among other options) which is six years old at this point. All of an Core i7-1260P's CPU cores enjoy access to 18 MB of L3 cache. The integrated memory controller supports various memory types up to LPDDR5-5200, DDR5-4800, LPDDR4x-4267 or DDR4-3200; Intel recommends using no more than 64 GB, for reference. Just like the other 12th Gen Intel Core processors, Intel Core i7-1260P comes with Thread Director which is a new functionality designed to help Windows 11 decide which cores to use for what workload for best performance and efficiency possible. Hardware acceleration of AI algorithms is supported via GNA 3.0 and DL Boost (via AVX2). PCI-Express 5.0 support has not found its way into Alder Lake P processors, so users will have to be content with PCI-Express 4.0 for the time being. Four PCI-Express 4 lanes allow for a read/write rate of up to 7.9 GB/s, provided a suitably fast NVMe SSD is used.
Please note this is not a user-replaceable CPU. It gets soldered permanently on to the motherboard (BGA1744 socket interface).
Performance
Multi-thread performance is most comparable to the Ryzen 7 5800U, Ryzen 7 PRO 5850U and also the Core i5-11260H. This makes the 1260P a great little CPU - one capable of punching above its weight.
Thanks to its decent cooling solution and a long-term CPU power limit of 35 W, the Asus ExpertBook B5 Flip B5602FBN is among the fastest laptops featuring the 1260P that we know of. It can be about 2 times as fast in CPU-bound workloads as the slowest system built around the same chip in our database (as of August 2023).
Graphics
The built-in graphics adapter in the form of the 96 EU Iris Xe running at up to 1.4 GHz has seemingly seen no change from what was built into certain Tiger Lake-UP3 processors, like a i7-1165G7. Which is hardly a downside as this iGPU is loaded with modern features such as AV1 video decoding capability and SUHD 4320p monitor support. Up to 4 monitors can be used simultaneously with this graphics adapter. Its gaming performance is bound to be tied to how high the Power Limits and how good the cooling solution of a laptop are; expect something close to NVIDIA's MX350 or in other words, acceptable framerates in most games when playing at 1080p / Medium settings. Fast RAM is a prerequisite for decent performance as the Iris Xe has to make do with no dedicated video memory. Last but not the least, we discovered that the GPU utilization when playing YouTube UHD 2160p60 videos is higher than it was with Tiger Lake chips.
Power consumption
The i7's base power consumption (also known as the default TDP or Power Limit 1) is 28 W, with 64 W being its maximum Intel-recommended Turbo power consumption (also known as the PL2). Its "Minimum Assured" power consumption sits at 20 W. All in all, an active cooling solution is a must for a CPU like this one here.
The i7-1260P is manufactured on Intel's fourth-gen 10 nm process marketed as Intel 7 for decent, as of late 2022, energy efficiency. Despite that, many 7 nm U-class AMD Ryzen 5000 parts are less power-hungry while being as fast (or even faster, depending on the workload) as the i7.
The Intel Core i5-7260U is a fast dual-core SoC for notebooks and Ultrabooks based on the Kaby Lake architecture and was announced in January 2017. The CPU has two processor cores clocked at 2.2-3.4 GHz (two cores also up to 3.4 GHz). The processor can execute up to four threads simultaneously thanks to Hyper Threading. It is also equipped with an Intel Iris Plus Graphics 640 GPU with 64 MB eDRAM, a dual-channel memory controller (DDR4) as well as VP9 and H.265 video decoding as well as encoding. The chip is still manufactured in a 14nm process with FinFET transistors.
Compared to the Core i7-7360U, the i5-7260 does have lower CPU (-200 MHz Turbo, -100 MHz Base) and GPU (-50 MHz) clocks.
Architecture
Intel basically uses the same micro architecture compared to Skylake, so the per-MHz performance does not differ. The manufacturer only reworked the Speed Shift technology for faster dynamic adjustments of voltages and clocks, and the improved 14nm process allows much higher frequencies combined with better efficiency than before.
Performance
At 2.2-3.4 GHz, the Core i5-7260U has much lower clocks compared to the old Core i5-6267U (2.9-3.3 GHz), but has slightly higher Turbo clocks. Similar to the 6267U, the i6-7260U can also use the 64 MB eDRAM, which should increase the performance in some scenarios.
Graphics
The integrated Intel Iris Plus 640 Graphics is the GT3e model of the Kaby Lake GPU (Intel Gen. 9.5). It has 48 Execution Units running at 300-950 MHz (i7 models up to 1050 MHz) and the performance is comparable to a GeForce 920MX thanks to fast eDRAM cache. However, there aren't any significant improvements compared to the old Iris Pro 540, so modern games can often not be played smoothly or only at the lowest or medium settings, respectively.
Contrary to Skylake, Kaby lake now also supports H.265/HEVC Main 10 with a 10-bit color depth as well as Google's VP9 codec. The dual-core Kaby Lake processors announced in January should also support HDCP 2.2.
Power Consumption
The chip is manufactured in an improved 14nm process with FinFET transistors, which improves the efficiency even further. Intel still specifies the TDP with 15 Watts, which is typical for ULV chips. Depending on the usage scenario, the TDP can vary between 7.5 (cTDP Down) and 25 Watts.
The Intel Celeron 3865U is an ULV (ultra low voltage) dual-core SoC based on the Kaby-Lake architecture and has been launched in the first quarter of 2017. The CPU can be found in ultrabooks as well as normal notebooks. In addition to two CPU cores clocked at 1.8 GHz (no Turbo Boost, no HyperThreading), the chip also integrates an HD Graphics 610 GPU and a dual-channel DDR4-2133/DDR3L-1600 memory controller. The SoC is manufactured using a 14 nm process with FinFET transistors.

The manufacturer only reworked the Speed Shift technology for faster dynamic adjustments of voltages and clocks, and the improved 14nm process allows much higher frequencies combined with better efficiency than before.
Performance
Due to the missing Turbo Boost and the low clock speeds, especially the single thread performance is very limited which results in a lower performance even for lower demanding tasks. The performance should be noticeably slower than the Celeron 3965 which offers 400 MHz higher clocked CPU cores. Therefore, the CPU is only suited for entry level tasks like office, web surfing and multimedia.
Graphics
The integrated graphics unit called HD Graphics 610 (similar to the HD Graphics 510) represents the "GT1" version of the Kaby Lake GPU (Intel Gen. 9). Its 12 Execution Units, also called EUs, are clocked at 300 - 900 MHz and offer a performance somewhat below the older HD Graphics 4400. Only a few games of 2015 can be played smoothly in lowest settings.
Power Consumption
Specified at a TDP of 15 W (including CPU, GPU and memory controller), the CPU is best suited for small notebooks and ultrabooks (11-inches and above). Optionally, the TDP can be lowered to 10 watts (cTDP down), reducing both heat dissipation and performance and allowing even more compact designs.
