Intel Core i5-13420H vs Intel Core i5-1334U vs Intel Core i7-13800H

Intel Core i5-13420H

The Intel Core i5-13420H is a mid-range mobile CPU for laptops based on the Raptor Lake-H series (Alder Lake architecture). It was announced in early 2023 and offers 4 of the 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 2.1 to 4.6 GHz (single core boost, all core up to 4.5 GHz) on the performance cluster and 1.5 to 3.4 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. 

Performance

Thanks to the higher clock speeds of the improved Intel 7 process, the Core i5-13420H can surpass the old Core i5-12450H (e.g., + 200 MHz boost).

Features

The integrated memory controller supports various memory types up to DDR5-5200 (up from DDR5-4800 of the i5-12500H). 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 48 of the 96 EUs (Execution Units).

The CPU is rated at 45 W base power (115 W PL2) but most laptops will use a PL1 of around 60 Watt. The SoC is manufactured in a further improved 10nm process at Intel, which is known as Intel 7.

Intel Core i5-1334U

The Intel Core i5-1334U is a mid-range 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 1.3 to 4.6 GHz on the performance cluster and 0.9 to 3.4 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 only "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 similar clock speed, the Core i5-1334U is very similar to the older Core i7-1250U (+100 MHz P-Cores base clock rate). The faster i7 like the i7-1365U models offer only higher clock rates (and a faster iGPU). Compared to the similar i5-1335U, the 1334U only supports slower LPDDR5-5200 (vs 6400 of the faster models) and is therefore slightly slower.

Architecture

The integrated memory controller supports various memory types up to LPDDR5-5200. 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 80 of the 96 EUs (Execution Units) operating at up to 1.25 GHz.

Power consumption

This Core i5 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.

Intel Core i7-13800H

The Intel Core i9-13900H is a high-end mobile CPU for laptops based on the Raptor Lake-H series (Alder Lake architecture). It was announced in early 2023 and offers 6 performance cores (P-cores, Golden Cove architecture) and 8 efficient cores (E-cores, Gracemont architecture). The P-cores support Hyper-Threading leading to 20 supported threads when combined with the E-cores. The clock rate ranges from 2.5 to 5.2 GHz (single core turbo, all-core 4.8 GHz) on the performance cluster and 1.8 to 4 GHz on the efficiency cluster. The performance of the E-cores should be similar to old Skylake cores (compare with the Core i7-6920HQ). All cores can use up to 24 MB L3 cache. The CPU supports the full set of vPro Enterprise management features.

Performance

Thanks to the high core count and high clock speed, the Core i7-13800H should be faster than the older Core i9-12900HK. Therefore, the CPU is very well suited for all demanding use cases like gaming, content creation, and scientific calculations.

Features

The integrated memory controller supports various memory types up to DDR5-5200 (up from 4800 MHz for 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.
