Intel Core i7-13620H vs Intel Core i5-11320H

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.

Intel Core i5-11320H

The Intel Core i5-11320H is a mid range SoC for thin and light gaming laptops and mobile workstations. It is based on the Tiger Lake H35 refresh generation and will be announced in Q3 2021. It integrates four Willow Cove processor cores (8 threads thanks to HyperThreading). The base clock speed depends on the TDP setting and can vary from 2.5 (28 W TDP) to 3.2 GHz (35 W). The boost of a single and two cores under load can reach up to 4.5 GHz. All four cores can reach up to 4.3 GHz. The L3 cache is reduced to 8 MB compared to the 12 MB of the higher end i7 models.

Thanks to the improved clock speeds, the performance gap to the faster i7-11370H should be quite small. The i7 still offers higher single and dual core Turbo speeds and more L3 cache.

The SoC also included the improved Xe graphics card with 96 CUs clocked at up to 1350 MHz.

Furthermore, Tiger Lake SoCs add PCIe 4 support (four lanes), AI hardware acceleration, and the partial integration of Thunderbolt 4/USB 4 and Wi-Fi 6 in the chip.

The chip is produced on the improved 10nm process (called 10nm SuperFin) at Intel, which should be comparable to the 7nm process at TSMC (e.g. Ryzen 4000 series).
