Architecture Differences

The two processors come from different architectural lineages and fabrication nodes. The Intel Core 7 350 uses the Wildcat Lake codename, built on a 3 nm process at Intel’s foundry. Its generation is listed as Core 5 (Wildcat Lake), indicating a newer design. The Intel Core i7-14650HX uses the Raptor Lake architecture, specifically Raptor Lake-HX, on a 10 nm process, and belongs to the Core 14th Gen series as a Raptor Lake-HX Refresh part.

Core counts differ significantly. The Core 7 350 provides 6 physical cores and 6 threads, meaning no hyper-threading. The i7-14650HX provides 16 cores and 24 threads, implying 8 performance cores with hyper-threading and 8 efficiency cores. This structural difference drives most of the performance gap in multithreaded scenarios.

Cache hierarchies also differ. The Core 7 350 has 192 KB of L1 cache per core, 2.5 MB of L2 per core, and 6 MB of shared L3 cache. The i7-14650HX has 80 KB of L1 per core, 2 MB of L2 per core, and 30 MB of shared L3 cache. Despite smaller per-core L1 and L2, the i7-14650HX’s larger total L3 cache (30 MB vs 6 MB) provides more shared capacity for multi-threaded workloads.

Memory support diverges as well. The Core 7 350 supports DDR5 and LPDDR5X with a single-channel memory bus and a recorded memory bandwidth of 59.7 GB/s. The i7-14650HX supports DDR4 and DDR5 with a dual-channel memory bus, though no bandwidth figure is recorded. The i7-14650HX also supports ECC memory, which the Core 7 350 does not.

PCIe connectivity differs. The Core 7 350 provides Gen 4 with 6 lanes (CPU only). The i7-14650HX provides Gen 5 with 16 lanes (CPU only), offering both newer generation and more lanes for expansion.

Integrated graphics differ. The Core 7 350 uses Intel Xe3 Graphics with 2 Xe cores. The i7-14650HX uses UHD Graphics 710.

The i7-14650HX has an unlocked multiplier, while the Core 7 350 is locked. Socket types differ: Intel BGA 1516 for the Core 7 350 and Intel BGA 1964 for the i7-14650HX. The i7-14650HX also has a recorded die size of 257 mm², while the Core 7 350 has no die size listed.

The Verdict

The Intel Core i7-14650HX is the clear choice for multithreaded performance. Its 16-core, 24-thread configuration delivers massive wins across every heavy workload in the database. In Cinebench R23 multi-core, it scores 20454 versus 8030, a 60.7% advantage. In Passmark integer math, it scores 116661 versus 33734, a 71.1% lead. The i7-14650HX also holds an 88th percentile ranking versus the Core 7 350’s 71st percentile.

The Intel Core 7 350 is the better option for single-thread responsiveness. It wins all three single-thread tests: Cinebench R15 single-core by 2.3%, Cinebench R23 single-core by 3.9%, and Passmark single-thread by 6.7%. Its 3 nm process and higher boost clock of 4.80 GHz (versus 5.20 GHz for the i7-14650HX) do not translate to a boost-clock advantage, yet the newer architecture yields faster single-core scores in these specific tests.
