Intel Core i7-13705H vs Intel Core i5-13500HX vs Intel Core i9-13905H

Intel Core i7-13705H

The Intel Core i7-13705H 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 2.4 to 5 GHz (single core turbo, all-core 4.7 GHz) on the performance cluster and 1.8 to 3.7 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. Similar to the i7-13700H but without vPro support and the 13705H uses a different package and socket.

Performance

Thanks to the high core count and high clock speed, the Core i7-13705H should be similar to the old top model, the Core i9-12900HK. Therefore, the CPU is very well suited for all demanding use cases like gaming, content creation, and scientific calculations. The performance should be identical to the Core i7-13700H.

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. 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 96 EUs (Execution Units) clocked at up to 1.5 GHz.

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 10nm process at Intel, which is known as Intel 7 (improved over the 12th Gen).

Intel Core i5-13500HX

The Intel Core i5-13500HX is a fast mid-range mobile processor of the Raptor Lake series. Is was announced in early 2023 and integrates 6 fast Raptor Cove performance cores (P-cores) with HyperThreading and 8 Gracemont efficiency cores without Hyper-Threading. The P-Cores clock between 2.5 GHz (base) up to 4.7 GHz (single core boost, all-core 4.5 GHz). The smaller E-Cores clock between 1.8 and 3.5 GHz. All cores can access the combined 24 MB L3 cache.

Compared to Alder Lake, Raptor Lake offers improved P-Cores (Raptor Cove micro-architecture) with bigger Caches and more E-Cores (same Gracemont micro-architecture). Furthermore, the chip supports faster DDR5 memory (up to 5600 MHz for the 13980HX, but only 4800 MHz for the i5).

Performance

The average 13500HX in our database is in the same league as the Ryzen 7 7745HX, Core i7-13705H, Core i9-12900HK, Core i9-13900H, Core i9-13905H, as far as multi-thread benchmark scores are concerned. This is a very, very fast CPU, as of mid 2023.

Your mileage may vary depending on how competent the cooling solution of your laptop is and how high the CPU power limits are.

Power consumption

The chip's "minimum assured" power consumption sits at 45 W. Its maximum Intel-recommended Turbo power consumption is 157 W and the Base power consumption is supposed to be around 55 W. Most laptop makers will go for a value much higher than 55 W to get better performance.

The i5-13500HX is manufactured on Intel's 4th generation 10 nm process marketed as Intel 7 for average, as of early 2023, energy efficiency.

Intel Core i9-13905H

The Intel Core i9-13905H 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 2.6 to 5.4 GHz (single core turbo, all-core 4.9 GHz) on the performance cluster and 1.9 to 4.1 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. Similar to the i9-13900H but without vPro support and the 13905H uses a different package and socket.

Performance

Thanks to the high core count and high clock speed, the Core i9-13905H is (together with the 13900HK) the fastest 45W CPU for laptops and only bested by Raptor Lake-HX based models with more cores and improved P-cores (e.g., the i9-13980HX). Still, the CPU is very well suited for all demanding use cases like gaming, content creation, and scientific calculations.
