Intel Core Ultra X7 358H
The Intel Core Ultra X7 358H is a 16-core mobile processor released in 2026, featuring Intel 18A microarchitecture and integrated Intel Arc B390 graphics.
The Intel Core Ultra X7 358H is a mobile processor built on the Intel 18A microarchitecture and fabricated on an 18 nm process node. It has 16 cores: 4 performance cores (P-cores) and 8 efficient cores (E-cores), with 16 threads. The base clock is 1.9 GHz, boosting up to 4.8 GHz. The cache hierarchy includes 2200 KB L1, 22 MB L2, and 18 MB L3 cache. The processor has a TDP of 25 W and a maximum turbo power of 80 W. It supports up to LPDDR5X 9600 MT/s memory across two channels, without ECC support. The integrated graphics is an Intel Arc B390 GPU. The CPU provides 12 PCIe lanes (PCIe 5.0 and 4.0) and uses socket FCBGA2540. It supports 64-bit, Intel SSE4.1, SSE4.2, and AVX2 instruction sets. The multiplier is locked. The processor was released on January 5, 2026.
