Comparison of the two processors

This comparison should tell us which of these two mobile CPUs is more powerful or which one should be preferred. The age of the two is identical; they both came onto the market in the first quarter of 2022. But that's about it for the similarities, the rest of the data reads quite differently. The AMD Ryzen 7 5825U is manufactured with a structure width of 7 nanometers and belongs to the fourth generation of AMD's Ryzen 7 family, while the Intel Core i7-1255U already belongs to the twelfth generation of the Intel Core i7 family and is manufactured using the larger 10 nanometer process becomes. The AMD processor is based on the Barcelo (Zen 3) architecture and is designed for the socket, while the Intel processor is based on the BGA 1744 socket and is based on the Alder Lake U architecture.

The AMD Ryzen 7 5825U has 8 identical processor cores that are based on a normal core architecture. The base clock of the eight cores is 2.00 gigahertz and the maximum turbo clock is 4.50 gigahertz. The processor also supports hyperthreading technology, which means it has up to 16 computing threads available. The Intel Core i7-1255U has 10 processor cores, which are arranged in a hybrid big.LITTLE architecture. In addition to 2 Golden Cove performance cores, 8 Gracemont efficiency cores are used here. The performance cores clock at up to 4.70 gigahertz and the 8 efficiency cores at a maximum of 3.50 gigahertz. Hyperthreading is only supported by the performance cores, meaning this processor has a maximum of 12 computing threads available.

The AMD Radeon RX Vega 8 (Renoir) is used as the internal graphics unit in the AMD Ryzen 7 5825U. This iGPU is manufactured using the 7-nanometer process, has 8 execution units and clocks at up to 2.00 gigahertz. The Intel Core i7-1255U also has an iGPU, with the Intel Iris Xe Graphics 96 (Alder Lake) integrated here. This graphics unit is manufactured using the 10-nanometer process, has 96 execution units and clocks at up to 1.25 gigahertz.

Both processors have 2 memory channels, whereby the AMD Ryzen 7 5825U can be operated with a maximum of 32 gigabytes of RAM, while the Intel Core i7-1255U supports the operation of up to 64 gigabytes of RAM.
