AMD Ryzen 3 2300U vs Intel Core i5-1235U vs AMD Ryzen 5 2600H

AMD Ryzen 3 2300U

The AMD Ryzen 3 2300U is a mobile APU for thin and light laptops that was announced in October 2017. It includes four Zen cores clocked at 2 to 3.4 GHz and offers no SMT (four threads) and 4 MB L3-Cache. The integrated graphics card is called Radeon RX Vega 6 and offers 6 CUs (384 Shaders) clocked at up to 1100 MHz. The TDP is configurable between 12 and 25 Watt (15 Watt nominal).

Intel Core i5-1235U

The Intel Core i5-1235U is a mid-range mobile CPU for thin and light laptops based on the Alder Lake architecture. It was announced in early 2022 and offers 2 performance cores (P-cores, Golden Cove architecture) and 8 efficient cores (E-cores, Gracemont architecture). The P-cores support Hyper-Threading leading to 12 supported threads when combined with the E-cores. The clock rate ranges from 1.3 to 4.4 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 12 MB L3 cache. Compared to the i5-1245U, the 1235U offers lower base clock speeds and only "Essentials" vPro management features. Compared to the P-series (28W) or H-series (45W), the 15W TDP may limit the sustained performance.

Performance

The average 1235U in our database is in the same league as the Ryzen 5 PRO 5650U and also, surprisingly enough, the i7-1250U and the i7-1260U, as far as multi-thread benchmark scores are concerned. This is a very respectable result, as of mid 2023.

Thanks to its decent cooling solution and a long-term CPU power limit of 27 W, the Beelink SEi12 is among the fastest systems built around the 1235U that we know of. It can be twice as fast in CPU-bound workloads as the slowest system featuring the same chip in our database, as of August 2023.

Architecture

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 80 of the 96 EUs (Execution Units) operating at up to 1.2 GHz.

Power consumption

This ULV processor has a Base power consumption of 15 W (also known as the long-term power limit), with 55 W being its maximum Intel-recommended Turbo power consumption. Both values are too high to allow for passively cooled designs.

Core i5-1235U is manufactured on Intel's fourth-gen 10 nm process marketed as Intel 7 for decent, as of mid-2022, energy efficiency.

AMD Ryzen 5 2600H

The AMD Ryzen 5 2600H is a mobile SoC that was announced late 2018. It is intended for mid-sized to big laptops and combines four Zen cores (8 threads) clocked at 3.2 (base) - 3.6 GHz (boost) with a Radeon RX Vega 8 Mobile graphics card with 8 CUs (512 Shaders, unverified). The integrated dual-channel memory controller supports up to DDR4-3200 memory.

Compared to the older Ryzen 5 2500U for slim and light laptops, the 2600H offers a higher TDP (45 Watt versus 15 Watt), higher clocked memory, a higher base clock (3.3 versus 2 GHz) and a faster integrated GPU.

The performance should be slightly better than the Ryzen 5 2600U due to the higher TDP and base clock speed. Especially longer loads should profit from this. Due to the high TDP (configurable from 35 - 54 Watt), the Ryzen 7 2600H is best suited for bigger laptops.
