► remove from comparison![Intel i7-1250U](fileadmin/_processed_/b/7/csm_Intel_Core_i7_badge_2020_12f92179ae.jpg)
The Intel Core i7-1250U is a 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 1.1 to 4.7 GHz on the performance cluster and 0.8 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 similar Core i7-1260U, the 1250U only offers "Essentials" vPro management features.
Performance
The average 1250U in our database is in the same league as the Ryzen 5 5500U; the i5-1240U, the i7-1260U and the i7-1265U are found close nearby as well.
Thanks to its decent cooling solution and a long-term CPU power limit of 23 W, the Envy x360 13-bf0013dx is among the fastest laptops built around the 1250U that we know of. It can be at least 30% faster in CPU-bound workloads than the slowest system featuring the same chip in our database, as of August 2023.
Features
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 adapter is based on the Xe architecture and offers all 96 EUs (Execution Units) operating at up to 0.95 GHz.
The CPU is rated at 9 W base power (TDP, PL1) and 29 W max. Turbo power (PL2) and the whole SoC is manufactured on a 10nm process at Intel, which is known as Intel 7.
Intel Celeron 5205U

The Intel Celeron 5205U is a power efficient entry-level dual-core SoC for notebooks based on the Comet Lake (CML-U) generation and was announced in October 2019. Compared to the similar Whiskey Lake Celeron 4205U processors, the difference is the higher clock speed (+100 MHz) and support for faster memory. The processor cores are clocked at only 1.9 GHz (no Turbo) and don't support SMT / HyperThreading (so only 2 threads). More information on Comet Lake and all the models and articles on it can be found here.
The integrated graphics adapter is still the same as in the previous generations. It is called only Intel UHD Graphics but is still the same Intel UHD Graphics 610 like in the Pentium 4205U. Furthermore, the SoC integrates a VP9 and H.265 de- and encoder and an integrated dual channel LPDDR3-2133/DDR4-2400 memory controller (compared to DDR4-2666 in the faster and costlier Core i3/i5/i7 processors).
Performance
While we have not tested a single system powered by the 5205U as of August 2023, it's safe to expect the chip to be about half as fast as the Core i3-10110U (Comet Lake, 2 cores, 4 threads, up to 4.1 GHz). Which is nothing to write home about, really, as of mid 2022.
Power consumption
This Celeron has a default TDP, also known as the long-term power limit, of 15 W. Intel officialy allows laptop manufacturers to reduce that value somewhat, 12.5 W being the lower limit, resulting in lower clock speeds and lower performance. Unlike most Comet Lake family processors, Celeron 5205U is fairly likely to actually stick to that limitation as its cores are not Boost-enabled.
Last but not the least, this CPU is manufactured on an old, as of late 2022, 14 nm Intel process making for subpar energy efficiency.
Intel Pentium Gold 6405U
► remove from comparison![Intel Pentium Gold 6405U](fileadmin/_processed_/9/1/csm_pentium_gold_066c35a3b4.jpg)
The Intel Pentium Gold 6405U is a power efficient entry-level dual-core SoC for notebooks based on the Comet Lake (CML-U) generation and was announced in October 2019. Compared to the similar Whiskey Lake Pentium 5405U processors, the difference is the higher clock speed (+100 MHz) and support for faster memory. The processor cores are clocked at 2.4 GHz (no Turbo). Thanks to HyperThreading 4 threads can be used. More information on Comet Lake and all the models and articles on it can be found here.
Due to the 100 MHz higher clock speed, the Pentium Gold 6405U should be slightly faster than the old Pentium 5405U and therefore in the entry level of mobile processors. The missing Turbo and only two cores are definitely a downside and therefore the CPU is best used for simple tasks like browsing and office programs. Compared to the faster Core i3, i5 and i7 Comet Lake models, the Pentium does not support SSE (2).
The integrated graphics card is still the same as in the previous generations. It is called only Intel UHD Graphics but is still the same Intel UHD Graphics 610 like in the Pentium 5405U. Furthermore, the SoC integrates a VP9 and H.265 de- and encoder and an integrated dual channel LPDDR3-2133/DDR4-2400 memory controller (compared to DDR4-2666 in the faster Core i3).
The chip is still produced in the 14nm++ process as Whiskey Lake. The TDP (PL1) is specified at 15 Watts but can be lowered to 12.5 Watt although the CPU then only runs at 800 MHz.
