Intel Core i7-13620H vs Intel Core i7-1355U
Intel Core i7-13620H
► remove from comparison
The Intel Core i7-13620H is a high-end mobile CPU for laptops of the Raptor Lake-H series (based on the Alder Lake architecture). It was announced in early 2023 and offers 6 performance cores (P-cores, Golden Cove architecture) and 4 of the 8 efficient cores (E-cores, Gracemont architecture). The P-cores support Hyper-Threading leading to 16 supported threads when combined with the E-cores. The clock rate ranges from 2.4 to 4.9 GHz (single-core boost, all-core boost up to 4.7 GHz) on the performance cluster and 1.8 to 3.6 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 24 MB L3 cache. Compared to the older i7-12650H, the 13620H offers higher clock speeds.
Performance
Thanks to the improved clock speeds, the i7-13620H should be able to clearly best the old i7-12650H. Still, the faster i7 models of the 13th gen offer more e-Cores and therefore a clearly better multi-threaded performance.
Features
The integrated memory controller supports various memory types up to DDR5-5200 (up from DDR5-4800 of the 12th gen.). 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 now supports PCIe 5.0 x8 for a GPU and two PCIe 4.0 x4 for SSDs.
The integrated graphics card is based on the Xe-architecture and offers 64 of the 96 EUs (Execution Units) clocked at up to 1.5GHz.
Power consumption
The i7-13620H is rated at a TDP of 55W (PL1, 115W PL2) and is manufactured in a further improved 10nm process (Intel 7) that allows the higher clock speeds compared to the 12th gen CPUs.
Intel Core i7-1355U
► remove from comparison
The Intel Core i7-1355U is a high-end mobile CPU for thin and light laptops based on the Alder Lake architecture (Raptor Lake-U / RPL-U series). It was announced in early 2023 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 5 GHz on the performance cluster and 1.2 to 3.7 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. The CPU supports "Essentials" vPro management features. Compared to the P-series (28W) or H-series (45W), the 15W TDP may limit the sustained performance.
Performance
Thanks to the high clock speed, the Core i7-1355U should perform slightly better than the older core i7-1265U (up to 4.8 GHz). The faster i7 like the i7-1365U models offer only higher clock rates (and a faster iGPU).
Architecture
The integrated memory controller supports various memory types up to LPDDR5-6400. 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 still only supports PCIe 4.0 x8 for a GPU and two PCIe 4.0 x4 for SSDs.
The integrated graphics card is based on the Xe-architecture and offers all 96 EUs (Execution Units) operating at up to 1.3 GHz.
Power consumption
This Core i7 CPU is rated at a TDP of 15W (base power, PL1) and a maximum turbo power of 55W (PL2). The RPL-U processors are built in a further improved Intel 7 process (10nm SuperFin) that allows higher clock rates.
