AMD Ryzen Embedded 9950X vs Intel Core Ultra 7 366H Comparison

The AMD Ryzen Embedded 9950X and Intel Core Ultra 7 366H occupy very different positions in the processor landscape, despite both featuring 16 cores. The AMD part is a desktop-class embedded processor built for sustained throughput, while the Intel chip is a mobile-focused part with a 25 W thermal envelope. Benchmark data for the Intel Core Ultra 7 366H shows a strong overall standing, with an average benchmark score of 41,263 and a percentile of 87 among all CPUs. The AMD Ryzen Embedded 9950X has no recorded benchmark scores in the database, so direct numerical comparison is limited to architectural and specification analysis. The recorded data for the Intel part shows its nearest rival is the Intel Core Ultra 7 356H, with a delta of 0.1%, followed closely by the AMD Ryzen AI 5 PRO 440 at 0.1%, then the AMD Ryzen 9 5900X at -0.3%, and the Intel Core Ultra X7 358H at 0.7%.

Head-to-Head Benchmarks

The database contains no head-to-head benchmark entries for these two processors, so a direct test-by-test comparison is not possible from recorded measurements. However, the Intel Core Ultra 7 366H has a full set of benchmark scores that indicate its performance profile. In Cinebench R23, the Intel chip scores 28,477 in multi-core and 4,020 in single-core. The Cinebench R20 results show 11,960 multi-core and 1,688 single-core, while Cinebench R15 shows 2,870 multi-core and 405 single-core. These scores place the Intel part in the upper tier of mobile processors, consistent with its 87th percentile ranking.

The PassMark suite for the Intel Core Ultra 7 366H reveals specific strengths. The multi-thread score is 33,429, and the single-thread score is 4,043. Integer math scores 83,695, while floating point math reaches 103,615. Data compression scores 327,455, data encryption scores 25,845, and extended instructions score 26,901. Find prime numbers scores 326, physics scores 2,880, and random string sorting scores 39,814.

Since the AMD Ryzen Embedded 9950X lacks benchmark entries, the analysis must rely on its architectural advantages. The AMD part supports simultaneous multithreading with 32 threads, double the thread count of the Intel chip. The higher thread count, combined with a boost clock of 5.70 GHz and 64 MB of L3 cache, suggests a substantial advantage in heavily threaded workloads, though no measured scores confirm this. The Intel part counters with a higher memory bandwidth of 115.2 GB/s compared to 89.6 GB/s, which benefits memory-intensive tasks. The Intel chip also has a distinct cache layout with 192 KB of L1 per core and 2.5 MB of L2 per core, while the AMD part uses 80 KB of L1 per core and 1 MB of L2 per core.

Architecture Differences

The two processors come from different architectural lineages. The AMD Ryzen Embedded 9950X uses the Granite Ridge codename and belongs to the Ryzen Embedded generation based on Zen 5. It is fabricated on a 4 nm process at TSMC and contains 16,630 million transistors across a die size of 2x 70.6 mm². The Intel Core Ultra 7 366H uses the Panther Lake architecture, with the Panther Lake-H generation designation. It is fabricated on a 3 nm process at Intel. The Intel chip has no recorded transistor count or die size in the database.

Core and thread configurations differ significantly. Both processors have 16 cores, but the AMD part supports 32 threads via simultaneous multithreading, while the Intel part has 16 threads with no multithreading. The AMD chip has a base clock of 4.30 GHz and a boost clock of 5.70 GHz. The Intel chip has a base clock of 2.00 GHz and a boost clock of 4.80 GHz. The power envelope is a major differentiator: the AMD part has a TDP of 170 W, while the Intel part has a TDP of 25 W. This 145 W difference reflects the desktop versus mobile design goals.

Cache hierarchies also differ. The AMD processor provides 80 KB of L1 per core, 1 MB of L2 per core, and 64 MB of L3 cache. The Intel processor provides 192 KB of L1 per core, 2.5 MB of L2 per core, and 18 MB of shared L3 cache. The AMD part has a much larger total L3 pool, while the Intel part has larger per-core L1 and L2 allocations. The memory support shows the Intel chip accepting both DDR5 and LPDDR5X, while the AMD chip supports DDR5 only. Both use dual-channel memory buses. The Intel part achieves a higher memory bandwidth at 115.2 GB/s versus 89.6 GB/s for the AMD part. ECC memory is supported on the AMD processor but not on the Intel processor.

PCIe lanes also differ. The AMD processor supports Gen 5 with 28 lanes (CPU only), while the Intel processor supports Gen 5 with 12 lanes (CPU only). The integrated graphics differ as well: the AMD part uses Radeon Graphics, and the Intel part uses Intel Xe3 Graphics. The AMD processor has an unlocked multiplier, while the Intel processor does not. The AMD part uses AMD Socket AM5, while the Intel part uses Intel BGA 2540, indicating a socketed desktop design versus a soldered mobile design.

Where Each One Wins

The Intel Core Ultra 7 366H demonstrates its strengths through the recorded benchmark data. Its 87th percentile ranking and average benchmark score of 41,263 indicate a strong overall performer in the mobile segment. The Cinebench R23 multi-core score of 28,477 and single-core score of 4,020 show balanced capability. The PassMark scores highlight particular strengths in data compression at 327,455 and floating point math at 103,615. These results indicate the Intel chip handles a wide range of productivity and computational tasks effectively within a 25 W power envelope. The higher memory bandwidth of 115.2 GB/s and support for LPDDR5X memory make it well suited for bandwidth-sensitive mobile workloads.

The AMD Ryzen Embedded 9950X, while lacking benchmark scores, has clear architectural advantages that point to specific use cases. The 32 threads versus 16 threads provides a theoretical doubling of parallel processing capacity. The boost clock of 5.70 GHz is 0.90 GHz higher than the Intel part, which should benefit single-threaded and lightly threaded workloads. The 64 MB of L3 cache is more than three times the 18 MB on the Intel part, which helps with working sets that exceed smaller cache capacities. ECC memory support makes the AMD part suitable for reliability-focused environments such as embedded servers and data integrity applications. The 28 PCIe Gen 5 lanes provide more expansion headroom than the 12 lanes on the Intel part. The 170 W TDP indicates the AMD part is designed for sustained high-performance operation rather than power efficiency.

The release dates show the AMD part launched on 2025-10-06, while the Intel part launched on 2026-01-04. Both are listed as active in production status. The AMD part belongs to the 9000 series, while the Intel part belongs to the Core Ultra Series 3. The market segments differ: the AMD part is desktop, and the Intel part is mobile.
