Analysis: Intel Core 7 350 vs Intel Core Ultra 5 245HX
The Verdict
The benchmark data presents a decisive outcome: the Intel Core Ultra 5 245HX wins all 17 recorded head-to-head comparisons against the Intel Core 7 350. The Core Ultra 5 245HX sits in the 90th percentile of all CPUs in the database, while the Core 7 350 lands in the 71st percentile. For workloads that depend on sustained multi-threaded throughput, such as rendering or data compression, the Core Ultra 5 245HX is the only rational choice between the two. The Core 7 350 is a low-power mobile part with a 15 W TDP, suited for systems where thermal and power constraints outweigh raw performance. The closest rival to the Core 7 350 is the Intel Core 5 221TE, which scores 0.5% higher on average, and the AMD Ryzen 5 3600XT, which sits 0.6% higher. The Core Ultra 5 245HX's nearest rival, the Intel Core Ultra 5 235A, scores 0.2% higher, while the Intel Core i5-14600K scores 0.7% higher. The data shows no scenario where the Core 7 350 wins a single recorded test.
Architecture Differences
The two processors diverge sharply in core configuration and platform design. The Intel Core 7 350 uses 6 cores with 6 threads, built on the Wildcat Lake codename under the Core 5 generation. Its process node is 3 nm, fabricated by Intel. The Intel Core Ultra 5 245HX belongs to the Core Ultra Series 2, uses the Arrow Lake architecture with the Arrow Lake-HX codename, and has 14 cores with 14 threads. It is also on a 3 nm process node, but fabricated by TSMC, with 17,800 million transistors on a 243 mm² die.
Cache hierarchies differ substantially. Both parts allocate 192 KB of L1 per core. The Core 7 350 has 2.5 MB of L2 per core and 6 MB of shared L3. The Core Ultra 5 245HX has 3 MB of L2 per core and 24 MB of shared L3. The L3 difference alone, 24 MB versus 6 MB, explains part of the multi-threaded performance gap in cache-sensitive workloads.
Memory support also separates them. The Core 7 350 supports DDR5 and LPDDR5X over a single-channel memory bus, with 59.7 GB/s of bandwidth. The Core Ultra 5 245HX supports only DDR5 but uses a dual-channel bus, delivering 102.4 GB/s. PCIe connectivity differs as well: the Core 7 350 provides Gen 4 with 6 lanes, while the Core Ultra 5 245HX provides Gen 5 with 20 lanes. Integrated graphics differ, with the Core 7 350 using Intel Xe3 Graphics with 2 Xe cores and the Core Ultra 5 245HX using Arc Xe-LPG Graphics with 48 execution units. The Core Ultra 5 245HX has an unlocked multiplier; the Core 7 350 does not.
Head-to-Head Benchmarks
The Core Ultra 5 245HX dominates every recorded test, but the magnitude varies. In Cinebench R23 multi-core, the Core Ultra 5 245HX scores 32,358 versus 8,030 for the Core 7 350, a delta of 75.2% in favor of the larger chip. That is the largest single gap in the dataset. Cinebench R20 multi-core shows a 60.5% delta, with scores of 13,590 and 5,373. Cinebench R15 multi-core also shows a 62.6% delta, with 3,261 versus 1,220.
Single-core results are closer but still favor the Core Ultra 5 245HX. In Cinebench R23 single-core, the Core Ultra 5 245HX scores 4,568 against 2,046, a 55.2% delta. Cinebench R20 single-core shows a 60.5% delta (1,918 versus 758). Cinebench R15 single-core shows a 36.5% delta (460 versus 292). The PassMark single-thread test shows the smallest margin in the entire dataset: 4,481 versus 4,100, a delta of only 8.5%. This indicates that the architectural efficiency of the Core 7 350, despite its low power envelope, is competitive on a per-thread basis, but the Core Ultra 5 245HX still holds the lead.
Memory-intensive and math-heavy workloads amplify the difference. PassMark data compression shows 393,071 versus 143,123, a 63.6% delta. Data encryption shows 30,022 versus 10,933, also 63.6%.
