Intel Core i5-13420H vs AMD Ryzen 7 7735HS

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.

AMD Ryzen 7 7735HS

The AMD Ryzen 7 7735HS is a processor for (gaming) laptops based of the Rembrandt Refresh generation. The R7 7735HS integrates all eight cores based on the Zen 3+ microarchitecture. They are clocked at 3.2 (guaranteed base clock) to 4.75 GHz (Turbo) and support SMT / Hyperthreading (16 threads). The chip is manufactured in 6 nm at TSMC. The 7735HS is the refresh of the Ryzen 7 6800HS with 50 MHz higher boost speed and a potential higher TDP up to 54W.

The Zen 3+ is a refresh of the Zen 3 architecture and should not offer a lot of changes. The chip offers modern features, like support for USB 4 (40 Gbps), PCI-E Gen 4 and DDR5-4800MT/s or LPDDR5-6400MT/s.

Performance

The average 7735HS in our database is in the same league as the Ryzen 5 7645HX, Ryzen 9 6900HS, Ryzen 9 6900HX, Core i5-12500H, Core i5-13500H, as far as multi-thread benchmark scores are concerned.

Thanks to its decent cooling solution and a long-term CPU power limit of 75 W, the Acer Nitro 16 AN16-41 is among the fastest laptops built around the 7735HS 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.

The integrated GPU Radeon 680M is still one of the fastest iGPUs (only bested by the new Radeon 780M). It is based on the RDNA2 architecture and offers 12 CUs at up to 2.2 GHz.

Power consumption

This Ryzen 7 CPU has a specified TDP of 35 W to 54 W (also known as the long-term power limit).
