Intel Core i5-3340M vs Intel Core i7-13705H

Intel Core i5-3340M

The Intel Core i5-3340M is a fast dual-core processor for laptops based on the Ivy Bridge architecture. Due to Hyperthreading, the two cores can handle up to four threads in parallel leading to better utilization of the CPU. Each core offers a base speed of 2.7 GHz but can dynamically increase clock rates with Turbo Boost up to 3.2 GHz (for 2 active cores) and 3.4 GHz (for 1 active core). As its predecessor Core i5-3320M, it offers a 3 MB L3-Cache.

Ivy Bridge is an enhanced die shrink of the Sandy Bridge architecture with improvements on both GPU and CPU performance. The CPUs are produced in 22nm (versus 32nm Sandy Bridge CPUs) and are the first to introduce 3D transistors for increased energy efficiency when compared to similarly clocked Sandy Bridge processors. Other new features are integrated PCI Express 3.0 and  DDR3(L)-1600 support.

The performance of the Core i5-3340M is slightly above a similarly clocked Sandy Bridge processor due to slight architectural improvements. As a result, overall performance is above the old i7-2640M.

The integrated Intel HD Graphics 4000 offers 16 Execution Units (EUs) clocked at 650 MHz up to 1250 MHz with Turbo Boost, making it one of the faster variants.

Just like most other Ivy Bridge dual-cores, the i5-3340M is rated at a TDP of 35 W. Therefore, even smaller laptops can use the Core i5.

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).
