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 will be 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.
Performance
The i7-13620H should be able to clearly best the old i7-12650H thanks to the improved clock speeds. However, the faster i7 models of the 13th gen offer more e-Cores and therefore a clearly better multi-threaded performance.
Features
The i7-13620H comes with various features that enhance its performance. 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).
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.
Comparison
When compared to other models in the Raptor Lake-H series, the i7-13620H has a lower core count but higher clock speeds. The i9-13900HK, i9-13900H, i7-13800H, i7-13700H all have 14/20 cores but clock speeds range from 1.9 to 5.4 GHz. The i5-13600H, i5-13500H, and i5-13420H have 12/16, 12/16 and 8/12 cores respectively but clock speeds range from 2.1 to 4.8 GHz.
Another important aspect to consider when evaluating the i7-13620H is its power consumption. With a TDP of 55W, the CPU is designed to operate within a specific power envelope, which can have an impact on the overall performance and battery life of the laptop. The 10nm manufacturing process used in the i7-13620H allows for higher clock speeds, but also contributes to a lower power consumption. This means that the CPU can operate at higher speeds while also keeping the power consumption in check.
When it comes to gaming performance, the i7-13620H offers an integrated graphics card based on the Xe-architecture, which offers 64 of the 96 EUs (Execution Units). While this is not the best GPU for gaming, it is still capable of running most games at 1080p resolution with medium to high settings. This makes it a good option for casual gamers or for those who want to play games on the go without the need for a dedicated GPU.
Another important aspect to consider when evaluating the i7-13620H is its compatibility with different memory types. The integrated memory controller supports DDR5-5200, which is an improvement over the DDR5-4800 supported by the 12th gen CPUs. This means that the CPU can handle faster memory speeds, which can have a positive impact on the overall performance.
In conclusion, the Intel Core i7-13620H is a powerful mobile CPU for laptops of the Raptor Lake-H series, based on the Alder Lake architecture. It offers improved clock speeds, advanced features, and a lower power consumption, making it a great option for demanding laptop users. However, its lower core count and integrated GPU limit its performance when compared to other models in the Raptor Lake-H series. Overall, the i7-13620H is a solid choice for those looking for a powerful CPU with good performance and advanced features.
