Intel Core i5-1250P vs AMD Ryzen 7 3750H vs Intel Core i7-1260P

Intel Core i5-1250P

The Intel Core i5-1250P is a mid-range Alder Lake-P family SoC designed for use in ultra-light, ultra-thin (yet actively cooled) laptops. It was announced in early 2022 and it has 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 i5's P-cores are Hyper-Threading-enabled for a total of 16 threads when combined with its E-cores. The clock speeds range from 1.7 GHz to 4.4 GHz for the performance cluster and 1.2 GHz to 3.3 GHz for the efficient cluster. The shortcomings of this processor as compared with the slightly faster Core i5-1260P include the smaller L3 cache, slower iGPU model, lower clock speeds. Full vPro feature set is enabled in the case of this i5, though ("Enterprise" tier, allowing for remote device management).

Architecture

The i5 is a continuation of Intel's efforts to use the ARM-developed big.LITTLE technology for its own benefit. A single "little" Alder Lake core is supposed to be 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 Core i5-1250P's CPU cores enjoy access to 12 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, this Core i5 comes with the 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). The alluringly fast PCI-Express 5.0 spec 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 permanently soldered on to the motherboard (FCBGA1744 socket interface).

Performance

The average 1250P in our database nearly matches the Ryzen 5 5500U and the Ryzen 5 PRO 6650U in multi-thread performance, trailing behind the Core i5-1240P just slightly. This is a great CPU for nearly all tasks imaginable, as long as one does not expect it to be as fast as the mighty Core i7-12700H.

Your mileage may vary depending on how high the Power Limits are and how competent the cooling solution of your system is. The latter is really important as a single Golden Cove core can eat more than 20 W when under heavy load.

Graphics

The built-in graphics adapter in the form of the 80 EU Iris Xe running at up to 1.4 GHz has seen little change from what was built into certain 11th Gen Tiger Lake UP3 processors, like a Core i5-1135G7, which is hardly a downside as this iGPU is loaded with modern features, AV1 video decoding capability and SUHD 4320p monitor support included. The Xe isn't a stranger to a bit of casual gaming; that said, your mileage may vary depending on how high the Power Limits are and how capable the cooling solution of a laptop is. Expect something close to NVIDIA's MX250 or in other words, acceptable framerates in most games when playing at 1080p / Low settings. Fast RAM is a prerequisite for decent performance as the Xe has to make do with no dedicated video memory.

Power consumption

The i5's base power consumption (also known as the default TDP or Power Limit 1) is 28 W; its maximum Turbo power consumption (also known as the PL2) is not supposed to exceed 64 W. As for the "Minimum Assured" power consumption, Intel's guidelines mention 20 W. All in all, an active cooling solution is a must for a CPU like this.

The i5-1250P is built with Intel's fourth-gen 10 nm manufacturing process marketed as Intel 7 for decent, as of late 2022, energy efficiency. Despite that, the i5 is more power-hungry than certain 7 nm U-class AMD Ryzen 5000 chips delivering similar, or even higher, performance.

AMD Ryzen 7 3750H

The AMD Ryzen 7 3750H is a mobile SoC that was announced in January 2019. It combines four Zen+ cores (8 threads) clocked at 2.3 - 4 GHz with a Radeon RX Vega 10 graphics card with 10 CUs (640 Shaders) clocked at up to 1400 MHz. Compared to the similar Ryzen 7 3700U, the 3750H offers a 20 Watt higher TDP and therefore a better performance under long periods of load. The integrated dual-channel memory controller supports up to DDR4-2400 memory. As the features of the Picasso APUs are the same compared to the Raven Ridge predecessors, we point to our Raven Ridge launch article.

Picasso SoCs use the Zen+ microarchitecture with slight improvements that should lead to a 3% IPS (performance per clock) improvements.

Performance

The average 3750H in our database is in the same league as the Core i7-10610U, as far as multi-thread benchmark scores are concerned. This is a fairly good result, as of early 2022.

The ROG Zephyrus G15 GA502DU is among the fastest laptops built around the 3750H that we know of. It can be about 20% faster in CPU-bound workloads than the slowest system featuring the same chip in our database, as of August 2023.

Power consumption

This Ryzen 7 has a default TDP of 35 W (also known as the long-term power limit). Laptop manufacturers are free to change that value to anything between 12 W and 35 W with clock speeds and performance changing accordingly. These values are comparatively high, making an active cooling solution pretty much a necessity.

Last but not the least, this AMD APU is built with a rather old, as of late 2022, 12 nm process for lower-than-average energy efficiency.

Intel Core i7-1260P

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.
