Intel Core i3-1315U vs AMD Ryzen 5 2400G

Intel Core i3-1315U

The Intel Core i3-1315U is a mid-range mobile CPU for thin and light laptops based on the Raptor Lake-U series. It was announced in early 2023 and offers 2 performance cores (P-cores, Golden Cove architecture) and 4 efficient cores (E-cores, Gracemont architecture). The P-cores support Hyper-Threading leading to 8 supported threads when combined with the E-cores. The clock rate ranges from 1.2 to 4.5 GHz on the performance cluster and 0.9 to 3.3 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 10 MB L3-cache. Compared to the faster i5 and i7 models, the i3 does not include vPro features.

Performance

Thanks to the 100 MHz higher Boost clock speed of the P-Cores, the i3-1315U should be slightly faster than the old i3-1215U.

Features

The integrated memory controller supports various memory types up to DDR5-4800, DDR4-3200, LPDDR5-5200, and LPDDR4x-4267. 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 only supports PCIe 4.0 (x8 for a GPU and two x4 for SSDs).

The integrated graphics card is based on the Xe-architecture and offers 64 of the 96 EUs (Execution Units) operating at up to 1.25 GHz.

The CPU is rated at 15 W base power (TDP, PL1) and 55 W max. Turbo power (PL2) and the whole SoC is manufactured in a further improved 10nm SuperFin process at Intel, which is known as Intel 7.

AMD Ryzen 5 2400G

The AMD Ryzen 5 2400G is a desktop APU that was announced in early 2018. It is the fastest Raven Ridge APU at that time and features all four Zen cores (8 threads due to SMT support) clocked at 3.6 - 3.9 GHz with a Radeon RX Vega 11 graphics card with 11 CUs (all of the 704 Shaders on the chip) clocked at up to 1250 MHz. The integrated dual-channel memory controller supports up to DDR-2933. The TDP is specified at 65 Watt and the CPU, GPU and memory are unlocked for overclocking.
