Intel Core 7 350 vs Intel Core Ultra 5 336H Comparison

The Intel Core 7 350 and Intel Core Ultra 5 336H are both active mobile processors from Intel, built on the same 3 nm process node. The recorded data, however, shows two very different performance profiles. The Core Ultra 5 336H delivers a commanding lead across nearly every benchmark, while the Core 7 350 secures a narrow but notable victory in a single-threaded PassMark test. The following analysis breaks down the head-to-head results, architectural differences, and the implications for system builders.

Head-to-Head Benchmarks

The benchmark data is unambiguous: the Intel Core Ultra 5 336H wins 15 of the 17 recorded tests. The largest margin comes in Cinebench R23 multi-core, where the Core Ultra 5 scores 23991 against the Core 7 350's 8030, a delta of -66.5%. This is the widest gap in the entire dataset and indicates a substantial multi-threaded performance advantage. The Cinebench R20 multi-core test tells a similar story, with the Core Ultra 5 scoring 10076 versus 5373, a -46.7% difference. The Cinebench R15 multi-core result shows 2418 against 1220, a -49.5% gap.

The single-core Cinebench results also favor the Core Ultra 5, though by smaller margins. In Cinebench R23 single-core, the Core Ultra 5 scores 3387 against 2046, a -39.6% delta. Cinebench R20 single-core shows 1422 versus 758, a -46.7% delta, and Cinebench R15 single-core shows 341 versus 292, a -14.4% delta. These results confirm that the Core Ultra 5 holds a clear advantage in both lightly threaded and heavily threaded workloads.

The PassMark suite reinforces the pattern. The Core Ultra 5 leads in data compression (280340 vs 143123, -48.9%), data encryption (21291 vs 10933, -48.6%), extended instructions (24542 vs 12045, -50.9%), and find prime numbers (299 vs 107, -64.2%). Floating point math shows 82415 versus 42809 (-48.1%), integer math shows 62070 versus 33734 (-45.7%), and multithread shows 28545 versus 15170 (-46.9%). Physics testing delivers 2682 versus 1173, a -56.3% delta, and random string sorting shows 34402 versus 17238 (-49.9%).

The single exception is the PassMark single-thread test, where the Core 7 350 wins with a score of 4100 against 4013, a delta of 2.2%. This is a narrow but decisive margin, and the same result appears twice in the dataset under slightly different test names. It suggests that the Core 7 350 has a slight edge in peak single-core frequency or efficiency, despite its lower scores elsewhere.

Overall, the average benchmark score for the Core Ultra 5 is 34485, placing it in the 84th percentile of all CPUs in the database. The Core 7 350 averages 17779, placing it in the 71st percentile. The nearest rivals for the Core Ultra 5 include the Intel Core i7-13700HX with an average score of 34554 (-0.2% delta) and the Intel Core i5-13450HX with 34333 (+0.4% delta). For the Core 7 350, the nearest rivals include the Intel Core 5 221TE at 17860 (-0.5%) and the AMD Ryzen 5 3600XT at 17891 (-0.6%). The Core Ultra 5 sits near the top of its peer group, while the Core 7 350 sits in the middle of a lower-performing cluster.

Architecture Differences

The two processors share the same 3 nm process node and Intel as the foundry, but their internal designs diverge significantly. The Core 7 350 is built on the Wildcat Lake codename, part of the Core 5 generation, while the Core Ultra 5 336H uses the Panther Lake architecture and belongs to the Core Ultra Series 3, specifically the Panther Lake-H generation.

Core counts differ sharply. The Core 7 350 has 6 cores and 6 threads, while the Core Ultra 5 336H has 16 cores and 16 threads. Neither processor supports simultaneous multithreading, so thread counts equal core counts. The Core Ultra 5's 16 cores provide the raw parallelism that drives its multi-core benchmark dominance.

Cache configurations also differ. Both processors have 192 KB of L1 cache per core and 2.5 MB of L2 cache per core. The shared L3 cache, however, is much larger on the Core Ultra 5: 18 MB shared versus 6 MB shared on the Core 7 350. This triples the L3 capacity and likely contributes to the Core Ultra 5's strong performance in memory-sensitive workloads like data compression and encryption.

Memory support is identical in type (DDR5 and LPDDR5X), but the memory bus and bandwidth differ. The Core 7 350 uses a single-channel memory bus with 59.7 GB/s of bandwidth, while the Core Ultra 5 336H uses a dual-channel bus with 115.2 GB/s. The doubling of memory bandwidth is a major architectural advantage for the Core Ultra 5, especially in multi-threaded and data-intensive tasks.

PCIe connectivity also differs. The Core 7 350 offers Gen 4 with 6 lanes (CPU only), while the Core Ultra 5 offers Gen 5 with 12 lanes (CPU only). The newer PCIe generation and doubled lane count give the Core Ultra 5 more headroom for discrete GPUs or fast NVMe storage.

The integrated graphics differ as well. The Core 7 350 includes Intel Xe3 Graphics with 2 Xe cores, while the Core Ultra 5 336H includes Intel Xe3 Graphics without a specified Xe core count in the data. Both processors have a base clock of 1.50 GHz (Core 7 350) and 1.90 GHz (Core Ultra 5), and boost clocks of 4.80 GHz and 4.60 GHz respectively. The Core 7 350 has a higher boost clock, which explains its narrow win in the PassMark single-thread test.

The thermal design power differs: the Core 7 350 is rated at 15 W, while the Core Ultra 5 336H is rated at 25 W. The higher TDP on the Core Ultra 5 reflects its larger core count and higher sustained performance envelope. The sockets also differ, with the Core 7 350 using Intel BGA 1516 and the Core Ultra 5 using Intel BGA 2540. Neither processor has an unlocked multiplier, and neither supports ECC memory.

The Core 7 350 has a launch MSRP of $469 and a release date of 2026-04-15. The Core Ultra 5 336H has no recorded launch MSRP and a release date of 2026-01-04, making it the earlier release of the two.

The Verdict

The benchmark data indicates that the Intel Core Ultra 5 336H is the superior processor for almost all workloads. It leads by wide margins in every Cinebench test, both multi-core and single-core, and dominates the PassMark suite across all categories except one. The largest gap, -66.5% in Cinebench R23 multi-core, shows that the Core Ultra 5 delivers roughly three times the multi-threaded performance of the Core 7 350. The -64.2% delta in PassMark find prime numbers and the -56.3% delta in physics further confirm the Core Ultra 5's advantage in compute-heavy tasks.

The Core 7 350's single win in PassMark single-thread (4100 vs 4013, +2.2%) is real but minimal. It indicates a slight edge in peak single-core performance, likely due to its 4.80 GHz boost clock versus the Core Ultra 5's 4.60 GHz. For applications that rely heavily on single-threaded responsiveness, the Core 7 350 holds a small advantage. However, the Core Ultra 5's single-core Cinebench scores are substantially higher (3387 vs 2046 in R23, -39.6%), suggesting that the PassMark single-thread result may not translate to all single-threaded workloads.

For systems that prioritize multi-core performance, content creation, data processing, or any parallel workload, the Core Ultra 5 336H is clearly the correct choice from the data. Its 16 cores, 18 MB L3 cache, dual-channel memory, and 115.2 GB/s bandwidth provide a strong foundation. For low-power, lightly threaded mobile applications where single-core speed and a 15 W TDP matter more, the Core 7 350 offers a competitive option, but its overall performance ceiling is far lower.

The percentile rankings support this view. The Core Ultra 5 sits in the 84th percentile of all CPUs, while the Core 7 350 sits in the 71st. The nearest rivals for the Core Ultra 5 include high-end desktop parts like the AMD Ryzen 7 3700X and the Intel Core i7-13700HX, while the Core 7 350's rivals are lower-tier mobile and desktop chips. The data clearly positions the Core Ultra 5 as the higher-performing part, with the Core 7 350 as a more power-efficient but substantially less capable alternative.
