► remove from comparison![Intel i5-1235U](fileadmin/_processed_/1/6/csm_Intel_Core_i5_badge_2020_81f91b42cc.jpg)
The Intel Core i5-1235U is a mid-range 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 1.3 to 4.4 GHz on the performance cluster and 0.9 to 3.3 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 i5-1245U, the 1235U offers lower base clock speeds 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 1235U in our database is in the same league as the Ryzen 5 PRO 5650U and also, surprisingly enough, the i7-1250U and the i7-1260U, as far as multi-thread benchmark scores are concerned. This is a very respectable result, as of mid 2023.
Thanks to its decent cooling solution and a long-term CPU power limit of 27 W, the Beelink SEi12 is among the fastest systems built around the 1235U that we know of. It can be twice as fast in CPU-bound workloads as 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 80 of the 96 EUs (Execution Units) operating at up to 1.2 GHz.
Power consumption
This ULV processor has a Base power consumption of 15 W (also known as the long-term power limit), with 55 W being its maximum Intel-recommended Turbo power consumption. Both values are too high to allow for passively cooled designs.
Core i5-1235U is manufactured on Intel's fourth-gen 10 nm process marketed as Intel 7 for decent, as of mid-2022, energy efficiency.
Qualcomm Snapdragon X Plus X1P-64-100
► remove from comparison![Qualcomm Snapdragon X Plus X1P-64-100](fileadmin/_processed_/f/e/csm_Snapdragon-X-Plus-May-2024_23bbf88d95.jpg)
The Snapdragon X Plus X1P-64-100 is an ARM architecture processor (SoC) for use in Windows laptops that debuted in April 2024. The X1P-64-100 has 10 Oryon CPU cores (6 P-cores and 4 E-cores) running at no more than 3.4 GHz. Other key features include a 3.8 TFLOPS Adreno GPU, a 45 TOPS Hexagon NPU and an impressively fast LPDDR5x-8448 memory controller.
The chip's smarter X Elite series brothers including first and foremost the Snapdragon X Elite X1E-84-100 use the same die with the same GPU and the same NPU but with more CPU cores, higher clock speeds on CPU cores as well as on the iGPU, and quite possibly higher power targets.
Architecture and Features
Qualcomm Oryon cores are said to be based on the ARM v8.7 microarchitecture. Much like modern AMD and Intel processors, the Snapdragon chip is compatible with USB 4 and thus with Thunderbolt 4; it remains to be seen if the X Plus is compatible with GeForce or Radeon discrete graphics cards.
The Qualcomm SoC is said to have 12 PCIe 4 and 4 PCIe 3 lanes for connecting various kinds of devices. NVMe SSDs are supported with a throughput of up to 7.9 GB/s; furthermore, most laptops built around the chip are expected to have 16 GB of LPDDR5X-8448 RAM. There is also a 45 TOPS NPU for accelerating AI workloads.
Performance
If the official performance data is any indication, the X Plus should be a whole lot slower than the 9-core Apple M4 in multi-thread workloads while being a lot more power-hungry. We'll make sure to update this section once we have in-house testing results.
Like any other Windows on ARM platform, the Snapdragon X chip works best with applications and games compiled specifically for ARM processors, of which there aren't many for the time being.
Graphics
The integrated Adreno GPU is supposed to be DirectX 12-compatible (not DirectX 12 Ultimate-compatible; as the rumors have it, there is no ray tracing of any kind here). It is also supposed to deliver up to 3.8 TFLOPS of performance. For reference, the slowest professional Nvidia Ada Generation graphics card for laptops, the RTX 500 Ada, delivers up to 9.2 TFLOPS.
The Qualcomm iGPU will let you use up to 3 UHD 2160p monitors simultaneously. 2160p120 integrated displays are supported, as are the popular AV1, HEVC and AVC video codecs (both decoding and encoding).
Power consumption
The X1P-64-100 is most likely going to be less power-hungry than its more powerful X Elite brothers. Expect to see anything between 10 W and 35 W under long-term workloads because that's what Ryzen U chips normally consume.
The SoC is built with a 4 nm TSMC process for decent, as of H1 2024, energy efficiency.
Intel Pentium 8500
► remove from comparison![Intel Pentium 8500](fileadmin/_processed_/7/d/csm_Intel_Pentium_badge_2020_Logo_691a7db873.jpg)
The Intel Pentium 8500 is an entry-level low-power mobile CPU for thin and light laptops based on the Alder Lake architecture. It was announced in early 2022 and offers one performance core (P-cores, Golden Cove architecture) and 4 efficient cores (E-cores, Gracemont architecture). The P-cores support Hyper-Threading leading to 6 supported threads when combined with the E-cores. The clock rate ranges from 1 to 4.4 GHz on the performance cluster and 0.7 to 3.3 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 8 MB L3-cache. Compared to the faster Core i3-1210U, the Pentium offers one less P-core.
Performance
While we have not tested a single system built around the 8500 as of August 2023, it's safe to expect the chip to be about 20% slower than the i3-1215U, as far as multi-thread performance is concerned. Which is pretty terrible as of Q3 2023.
Your mileage may vary depending on how high the CPU power limits are and how competent the cooling solution of your system is.
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 48 of the 96 EUs (Execution Units) operating at up to 0.8 GHz.
Power consumption
This Pentium has a Base power consumption of 9 W, with 29 W being its maximum Intel-recommended Turbo power consumption. TDP values this low allow for passively cooled laptops, tablets, mini-PCs as long as performance is not a priority.
The CPU is made with Intel's 3rd generation 10 nm process marketed as Intel 7 for decent, as of early 2023, energy efficiency.
