Intel Core 7 350 vs Intel Core i5-14500HX Comparison

The Verdict

The benchmark data is decisive: the Intel Core i5-14500HX wins 15 of 17 head-to-head tests, while the Intel Core 7 350 wins only 2. The i5-14500HX delivers an average benchmark score of 35094 versus 17779 for the Core 7 350, placing it in the 84th percentile of all CPUs compared to the 71st percentile for the Core 7 350. For multi-threaded workloads, rendering, and compressed data handling, the i5-14500HX is the clear choice. The Core 7 350 retains one specific advantage: single-threaded PassMark performance, where it scores 4100 against 3629, a 13% lead. That makes the Core 7 350 suitable for lightly threaded tasks that rely heavily on single-core speed, but its 6-core, 6-thread configuration limits it in almost every parallel workload measured.

Architecture Differences

The two processors come from different design lineages. The Intel Core 7 350 uses the Wildcat Lake codename and is built on a 3 nm process node. The Intel Core i5-14500HX uses the Raptor Lake architecture with the Raptor Lake-HX codename and a 10 nm process node. The Core 7 350 has 6 cores and 6 threads, while the i5-14500HX has 14 cores and 20 threads. That difference in core count directly explains the multi-threaded benchmark gaps.

Cache structures also diverge significantly. The Core 7 350 has 192 KB of L1 cache per core, 2.5 MB of L2 cache per core, and 6 MB of shared L3 cache. The i5-14500HX has 80 KB of L1 cache per core, 2 MB of L2 cache per core, and 24 MB of shared L3 cache. Although per-core L1 and L2 are larger on the Core 7 350, the i5-14500HX has four times the shared L3 capacity, which benefits multi-core workloads that share data.

Memory support differs 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 i5-14500HX supports DDR4 and DDR5 with a dual-channel memory bus; memory bandwidth is not recorded for it. ECC memory is supported on the i5-14500HX but not on the Core 7 350. PCIe connectivity also differs: the Core 7 350 offers Gen 4 with 6 lanes (CPU only), while the i5-14500HX offers Gen 5 with 16 lanes (CPU only).

Integrated graphics units differ: the Core 7 350 uses Intel Xe3 Graphics with 2 Xe cores, while the i5-14500HX uses UHD Graphics 770. The i5-14500HX has an unlocked multiplier; the Core 7 350 does not. The Core 7 350 has a die size not recorded, while the i5-14500HX has a die size of 257 mm².

Head-to-Head Benchmarks

In Cinebench R20 multi-core, the i5-14500HX scores 10178 versus 5373, a 47.2% lead. In Cinebench R15 multi-core, the i5-14500HX scores 2442 versus 1220, a 50% lead. These results indicate the i5-14500HX is roughly twice as fast in multi-threaded rendering tasks.

Single-core Cinebench results favor the i5-14500HX as well, though by smaller margins. In Cinebench R23 single-core, the i5-14500HX scores 3421 versus 2046, a 40.2% lead. In Cinebench R20 single-core, it scores 1436 versus 758, a 47.2% lead. In Cinebench R15 single-core, it scores 344 versus 292, a 15.1% lead.

PassMark integer math shows the largest gap. The i5-14500HX scores 95584 versus 33734, a 64.7% advantage. Data compression follows: 333851 versus 143123, a 57.1% lead. Random string sorting shows 36219 versus 17238, a 52.4% lead. PassMark multithread scores 28508 versus 15170, a 46.8% lead. Data encryption scores 19502 versus 10933, a 43.9% lead. Extended instructions score 20019 versus 12045, a 39.8% lead. Floating point math scores 69442 versus 42809, a 38.4% lead. Physics scores 1911 versus 1173, a 38.6% lead. Find prime numbers scores 130 versus 107, a 17.7% lead.

The Core 7 350 wins only in PassMark single-threaded tests. Both passmark_single_thread and passmark_singlethread record identical scores: 4100 for the Core 7 350 versus 3629 for the i5-14500HX, a 13% lead. This is the sole head-to-head category where the Core 7 350 prevails.

Where Each One Wins

The Intel Core i5-14500HX wins in every multi-threaded benchmark recorded. Its 14 cores and 20 threads provide a large parallel workload advantage. Cinebench R23 multi-core shows a 66.9% lead, and PassMark integer math shows a 64.7% lead. Data compression, encryption, extended instructions, floating point math, physics, random string sorting, and multithread tests all favor the i5-14500HX by margins between 38.4% and 57.1%. The i5-14500HX also wins all single-core Cinebench tests, with leads from 15.1% to 47.2%. Its 24 MB L3 cache and dual-channel memory bus support these results. The i5-14500HX is the appropriate choice for rendering, compilation, data processing, or any workload that can use more than 6 threads.

The Intel Core 7 350 wins only in PassMark single-threaded tests, with a 13% lead over the i5-14500HX. Its 3 nm process node and larger per-core L1 and L2 caches may contribute to this result. The Core 7 350 also has a lower TDP of 15 versus 55, which indicates a lower power envelope, though the database does not record actual power consumption. For applications that are strictly single-threaded and cannot use additional cores, the Core 7 350 delivers higher single-thread PassMark performance. For everything else measured, the i5-14500HX is the stronger processor.
