Architecture Differences

The two processors come from different design generations and manufacturing processes. The Intel Core 7 350 uses the Wildcat Lake codename on a 3 nm process node, while the Intel Core i7-14700HX uses Raptor Lake-HX on a 10 nm node. Both are manufactured by Intel.

Core counts differ dramatically. The Core 7 350 has 6 cores and 6 threads, meaning no hyper-threading. The Core i7-14700HX has 20 cores and 28 threads. The cache hierarchy also diverges. 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 Core i7-14700HX has 80 KB of L1 per core, 2 MB of L2 per core, and 33 MB of shared L3 cache. The Core i7-14700HX also has a recorded die size of 257 mm², while the Core 7 350 has no die size recorded.

Clock speeds favor the Core i7-14700HX on paper. Its base clock is 2.10 GHz and boost clock is 5.50 GHz, compared to the Core 7 350's 1.50 GHz base and 4.80 GHz boost. The thermal design power also differs, with the Core 7 350 rated at 15 W and the Core i7-14700HX at 55 W.

Memory support and platform features separate the two further. The Core 7 350 supports DDR5 and LPDDR5X memory over a single-channel bus with 59.7 GB/s bandwidth. The Core i7-14700HX supports DDR4 and DDR5 over a dual-channel bus, with no bandwidth figure recorded. The Core i7-14700HX supports ECC memory, while the Core 7 350 does not. PCIe connectivity differs as well: the Core 7 350 provides Gen 4 with 6 CPU lanes, while the Core i7-14700HX provides Gen 5 with 16 CPU lanes.

Integrated graphics differ. The Core 7 350 uses Intel Xe3 Graphics with 2 Xe cores, while the Core i7-14700HX uses UHD Graphics 770. The Core i7-14700HX has an unlocked multiplier, whereas the Core 7 350 does not. Sockets differ too: the Core 7 350 uses Intel BGA 1516 and the Core i7-14700HX uses Intel BGA 1964. The Core 7 350 has a recorded launch MSRP of $469 and a release date in April 2026, while the Core i7-14700HX has no launch MSRP recorded and an earlier release date in January 2024.

The Verdict

The benchmark data indicates that the Intel Core i7-14700HX is the stronger processor for compute-intensive work. It wins 15 of 17 recorded tests, with multi-core advantages ranging from 35.2% to 74.3%. Its 20 cores and 28 threads, combined with a 5.50 GHz boost clock and 33 MB of L3 cache, deliver results that place it at the 89th percentile of all CPUs. The average benchmark score of 45953 is roughly 2.6 times the Core 7 350's 17779.

The Core 7 350's single competitive area is single-thread PassMark performance, where it leads by 3.9%. In Cinebench single-core tests, the two are nearly tied, with the Core i7-14700HX ahead by only 1.4% and 2.7%. This suggests that for lightly threaded applications, the Core 7 350 is not significantly disadvantaged despite its lower core count and clock speeds. However, the Core 7 350's 6 cores and 6 threads cannot keep pace in parallel workloads. Its 71st percentile ranking and 15 W TDP indicate a design aimed at efficiency, while the Core i7-14700HX's 55 W TDP and larger die size point toward performance.

The data does not show any workload category where the Core 7 350 wins beyond the single PassMark single-thread test. Every multi-threaded, encryption, compression, physics, and instruction-heavy benchmark goes to the Core i7-14700HX by wide margins. For users prioritizing raw throughput, the Core i7-14700HX is the clear choice. For users prioritizing single-thread responsiveness in a lower-power package, the Core 7 350 holds a narrow edge in one metric but is otherwise comparable in single-core Cinebench results.

Where Each One Wins

The Intel Core i7-14700HX wins in every multi-threaded and parallel workload recorded. Cinebench R15, R20, and R23 multi-core tests all show leads between 58.9% and 68%. PassMark multithread is 58.5% higher. Integer math, floating point math, data compression, data encryption, extended instructions, random string sorting, physics, and prime number finding all favor the Core i7-14700HX by margins from 35.2% to 74.3%. The 20-core, 28-thread configuration and 33 MB L3 cache clearly drive these results.

The Intel Core 7 350 wins the PassMark single-thread test with a 3.9% edge (4100 vs 3947). This is its only recorded victory. In Cinebench R15 and R23 single-core, the Core 7 350 trails by only 1.4% and 2.7% respectively, meaning the single-thread performance gap is small. The 3 nm process node and higher L1 cache per core (192 KB vs 80 KB) may contribute to this competitive single-thread showing.

For workloads that scale with core count, the Core i7-14700HX is the decisive winner. For workloads that rely on a single thread, the Core 7 350 holds a marginal advantage in one measurement and is nearly even in others. The Core 7 350's 15 W TDP also indicates a lower power envelope than the Core i7-14700HX's 55 W rating, though the recorded data does not include power consumption measurements. The Core i7-14700HX supports ECC memory and PCIe Gen 5 with 16 lanes, features absent from the Core 7 350. The Core 7 350 supports LPDDR5X memory, which the Core i7-14700HX does not.
