Intel Core i7-13620H vs AMD Ryzen 7 7735U

Intel Core i7-13620H

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.

AMD Ryzen 7 7735U

The AMD Ryzen 7 7735U is a processor for mid-sized laptops based of the Rembrandt refresh generation. The R7 7735U integrates all eight cores based on the Zen 3+ microarchitecture. They are clocked at 2.7 (guaranteed base clock) to 4.75 GHz (Turbo) and support SMT / Hyperthreading (16 threads). The chip is manufactured on the modern 6 nm TSMC process. Compared to the previous Ryzen 7 6800U, the 7735U offers 50 MHz higher boost clock and a slightly higher TDP of 28W (vs 15-25W).

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 7735U in our database is in the same league as the Core i7-1270P, Ryzen 5 6600H, Ryzen 7 5825U, Ryzen 7 PRO 6850U, as far as multi-thread benchmark scores are concerned. The chip is absolutely capable of making most consumers happy, as of mid 2023; of course, your mileage may vary depending on how competent the cooling solution of your system is and how high the CPU power limits are.

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.

The Ryzen 7735U is manufactured in 6nm FinFET at TSMC and specified at a TDP of 28W.
