Where Each One Wins

The Intel Core Ultra X7 358H wins in every category where data exists. It has more cores (16 versus 14), a higher boost clock (4.80 GHz versus 4.60 GHz), more L2 cache per core (3 MB versus 2.5 MB), and greater memory bandwidth (153.6 GB/s versus 136.5 GB/s). Its integrated graphics are the Arc B390, a higher-tier part than the Arc B370 in the Arc G3.

Benchmark results reinforce this position. The Ultra X7 358H's 18747 Cinebench R23 multi-core score and 2080 single-core score place it well within competitive range of its nearest rivals. The narrow deltas against the AMD Ryzen AI 5 PRO 440 (-0.6%), Intel Core Ultra 7 356H (-0.6%), AMD Ryzen AI 5 PRO 435G (+0.6%), and Intel Core Ultra 7 366H (-0.7%) show that the Ultra X7 358H performs at parity with the upper tier of its segment.

The Intel Arc G3 has no recorded wins because it has no recorded benchmarks. Its 50th percentile ranking and zero average score mean it cannot be positioned against the Ultra X7 358H based on measured performance. The only advantages it offers are structural: a later release date and a lower part number, neither of which affects workload capability. For any application that depends on multi-threaded throughput, single-thread responsiveness, or memory bandwidth, the Ultra X7 358H is the only one of the two with data to support a claim.

Use cases favor the Ultra X7 358H accordingly. Multi-threaded rendering workloads, as represented by Cinebench R23 at 18747 points, benefit from its 16 cores and higher L2 cache. Memory-intensive operations, supported by 153.6 GB/s of bandwidth, gain from the wider data path. The Arc B390 integrated graphics provide a stronger baseline for display output and light GPU tasks.

The Arc G3 remains a functional mobile processor with identical base clock, socket, and process node. Its 14 cores and 4.60 GHz boost clock are capable figures for general productivity. But without benchmark data, its real-world standing cannot be quantified, and the database shows no evidence that it competes with the Ultra X7 358H on any measured axis.
