The Intel Core Ultra X7 358H is the second-fastest Panther Lake SKU carrying the full 12-core Arc iGPU, positioned below the X7 368H and X9 388H in clock speed. It shares the same 4 P-core, 8 E-core, 4 LPE-core layout as the rest of the X-series, with P-cores boosting up to 4.8 GHz, E-cores up to 3.7 GHz, and the small LPE-cores up to 3.3 GHz. Power draw is specified across a wider range than the higher X-series chips: 15W minimum assured power, 25W processor base power, and up to 55W maximum Turbo power, giving OEMs more flexibility in how aggressively a given laptop chassis pushes the chip. Memory support reaches up to 96GB of LPDDR5-9600. Platform connectivity includes 12 PCIe lanes, four Thunderbolt 4 ports, WiFi 7 (R2), and Bluetooth Core 6.0, all routed through a platform controller tile also fabricated at TSMC.

Intel Arc (12 Xe3-cores)
The X7 358H carries the same 12-Xe3-core iGPU family as the X9 388H and X7 368H, with ray tracing support, though running at the lower clock ceiling that comes with this SKU's overall lower power envelope.
How Is the Core Ultra X7 358H in Terms of Performance
As the lowest-clocked member of the full-iGPU X-series tier, the X7 358H trades some peak performance against its X7 368H and X9 388H siblings for a lower guaranteed power floor, making it a better fit for thinner chassis designs that can't sustain the higher-end chips' peak boost states. It still carries Intel's platform-wide Panther Lake performance claims of up to 60% better multithreaded performance and up to 77% faster gaming versus the outgoing generation, though actual gains will run toward the lower end of that range given the reduced clock ceiling.
Benchmarks
Expect Geekbench 6 single-core scores a step behind the X9 388H and X7 368H given the lower 4.8 GHz P-core ceiling, with the gap most visible in short, latency-sensitive tasks. Multi-core scores should land closer to its siblings under sustained load, since all three chips share the same core count and cache configuration.
