AMD Ryzen Embedded 9950X vs Intel Core Ultra X7 358H Comparison

Head-to-Head Benchmarks

The recorded data for the AMD Ryzen Embedded 9950X contains no benchmark entries, leaving its measured performance profile absent from the database. The Intel Core Ultra X7 358H, by contrast, has a full set of 17 recorded benchmark scores across Cinebench and Passmark workloads. This asymmetry means the head-to-head comparison relies entirely on the Intel part's measured results, while the AMD part's capabilities must be assessed from its architectural specifications alone.

The Intel Core Ultra X7 358H delivers a Cinebench R23 multi-core score of 18,747 points and a single-core score of 2,080 points. In Cinebench R20, it records 12,011 multi-core and 1,695 single-core. The older Cinebench R15 run yields 3,027 multi-core and 301.5 single-core. These scores place the Intel processor at the 87th percentile among all CPUs in the database, with an average benchmark score of 40,967.

Passmark results for the Intel part show a multi-thread score of 33,802 and a single-thread score of 4,124. Integer math reaches 83,147, floating point math reaches 103,842, and extended instructions score 27,274. Data compression records 332,508, data encryption records 26,046, and random string sorting records 40,357. Physics simulation scores 3,021, while finding prime numbers records 337.

The nearest rivals for the Intel Core Ultra X7 358H, based on average benchmark scores, are all within a narrow band. The AMD Ryzen AI 5 PRO 440 averages 41,208, which is 0.6% below the Intel part. The Intel Core Ultra 7 356H averages 41,215, also 0.6% below. The AMD Ryzen AI 5 PRO 435G averages 40,718, which is 0.6% above the Intel part. The Intel Core Ultra 7 366H averages 41,263, 0.7% below. The Intel Core Ultra X7 358H therefore sits in a tightly clustered group where the largest recorded gap to any nearest rival is 0.7%.

Because the AMD Ryzen Embedded 9950X has no recorded scores, the database cannot produce a direct numeric comparison between the two processors. The Intel part's percentile rank of 87 indicates it outperforms the large majority of CPUs in the database, but the AMD part's percentile of 50 is based on its specification profile rather than measured results, so it does not represent an equivalent benchmark-derived ranking.

Where Each One Wins

The Intel Core Ultra X7 358H wins exclusively in measured performance categories, as it is the only part with benchmark data. Its Cinebench R23 multi-core score of 18,747 and single-core score of 2,080 demonstrate strength across both heavily threaded and lightly threaded workloads. The Passmark multi-thread score of 33,802 and single-thread score of 4,124 reinforce this pattern, showing competitive throughput in both parallel and sequential tasks.

The AMD Ryzen Embedded 9950X wins in structural specifications that favor high-throughput desktop computing. It offers 16 cores and 32 threads, double the thread count of the Intel part. Its base clock of 4.30 GHz and boost clock of 5.70 GHz are substantially higher than the Intel part's 1.90 GHz base and 4.80 GHz boost. The AMD processor carries 64 MB of L3 cache, a 64 MB L2 cache allocation across 16 cores (1 MB per core), and an 80 KB L1 allocation per core. The Intel part has 18 MB of shared L3 cache, 3 MB of L2 per core, and 192 KB of L1 per core. The AMD part's larger L3 pool and higher thread count point toward multi-threaded server-style workloads, while the Intel part's measured scores point toward mobile efficiency with competitive single-thread performance.

The AMD part also supports ECC memory, a feature the Intel part lacks, and offers 28 PCIe Gen 5 lanes from the CPU, compared to 4 lanes on the Intel part. Its memory bandwidth is rated at 89.6 GB/s over dual-channel DDR5, while the Intel part's dual-channel LPDDR5X bandwidth is rated at 153.6 GB/s. The Intel part's higher memory bandwidth, despite the AMD part's larger cache, gives the mobile chip an advantage in memory-intensive measured workloads.

The Verdict

The database contains measured performance data for only one of these two processors. The Intel Core Ultra X7 358H records an average benchmark score of 40,967 and sits at the 87th percentile of all CPUs, with its nearest rivals all within 0.7% of its average score. This places it in a tightly competitive mobile segment where performance differences between similar parts are minimal. Its 25 W TDP, 3 nm Intel process, and 153.6 GB/s memory bandwidth make it a low-power mobile part with strong measured throughput.

The AMD Ryzen Embedded 9950X has no measured scores, so its average benchmark score of 0 and 50th percentile reflect an absence of data rather than a performance result. Its specifications, however, describe a high-power desktop processor with 170 W TDP, 32 threads, a 5.70 GHz boost clock, 64 MB of L3 cache, and 28 PCIe Gen 5 lanes. It targets a different usage envelope entirely, one built around embedded desktop workloads that require high core counts, large cache pools, ECC memory support, and extensive I/O connectivity.

For applications where measured benchmark data matters, the Intel Core Ultra X7 358H is the only part with recorded results, and those results show a capable mobile processor performing at the 87th percentile. For applications where thread count, cache capacity, ECC support, and PCIe lane count are the deciding factors, the AMD Ryzen Embedded 9950X offers structural advantages, though its actual performance remains unmeasured in the database. The choice between the two depends entirely on whether the workload prioritizes the Intel part's verified mobile performance or the AMD part's desktop-oriented specification sheet.
