AMD Ryzen Embedded 9900X3D vs Intel Core i7-14700HX Comparison

Head-to-Head Benchmarks

The benchmark database does not contain any recorded head-to-head test results between the AMD Ryzen Embedded 9900X3D and the Intel Core i7-14700HX. The headToHeadBenchmarks field is empty, and neither processor has a wins tally in direct comparisons. However, the Intel Core i7-14700HX has a substantial set of individual benchmark scores, while the AMD Ryzen Embedded 9900X3D has no recorded benchmark scores at all in the database. This absence of data for the AMD part means any direct performance comparison must rely on architectural analysis rather than measured results.

The Intel Core i7-14700HX delivers a Cinebench R23 multi-core score of 24595 and a single-core score of 2103. In Cinebench R20, it records 13059 multi-core and 1843 single-core. The older Cinebench R15 test shows 3812 multi-core and 296 single-core. Geekbench results stand at 14390 multi-core and 2116 single-core. PassMark tests reveal a multi-thread score of 36566 and a single-thread score of 3947. Additional PassMark subtests include floating point math at 93836, integer math at 131296, extended instructions at 25718, data compression at 438539, data encryption at 26092, find prime numbers at 165, physics at 2252, and random string sorting at 48544.

The Intel processor holds an average benchmark score of 45953 and sits at the 89th percentile among all CPUs in the database. Its nearest rivals are tightly clustered: the AMD EPYC 7303 scores 45960 with a 0% delta, the AMD EPYC 4364P scores 45970 with a 0% delta, the AMD Ryzen AI 9 HX 375 scores 46030 with a -0.2% delta, and the Intel Core Ultra 5 235 scores 46062 with a -0.2% delta. This clustering indicates the i7-14700HX performs essentially at parity with those four processors, trailing the fastest among them by only 0.2%. The AMD Ryzen Embedded 9900X3D, by contrast, has an average benchmark score of zero and a 50th percentile ranking, reflecting the complete lack of recorded test data rather than actual performance characteristics.

Architecture Differences

The AMD Ryzen Embedded 9900X3D belongs to the Ryzen Embedded series within the 9000 series lineup, built on the Granite Ridge codename and Zen 5 architecture. It uses a 4 nm process node manufactured by TSMC, with a transistor count of 16,630 million spread across a dual-chiplet design with a die size of 2x 70.6 mm². The Intel Core i7-14700HX comes from the Core 14th Gen series, uses the Raptor Lake architecture with the Raptor Lake-HX codename, and is built on a 10 nm process node by Intel with a monolithic die size of 257 mm². The transistor count for the Intel part is not recorded in the database.

The cache hierarchies differ notably. Both processors allocate 80 KB of L1 cache per core, but the L2 cache differs: AMD provides 1 MB per core, while Intel provides 2 MB per core. The L3 cache presents the largest architectural divergence, with AMD offering 128 MB total versus Intel's 33 MB shared. The AMD part does not list a 3D V-Cache specification in the database, so the large L3 capacity cannot be attributed to that technology in this analysis.

The AMD processor uses AMD Socket AM5, while the Intel processor uses Intel BGA 1964, reflecting their different market segments: desktop for AMD and mobile for Intel. The AMD part supports DDR5 memory only, while the Intel part supports both DDR4 and DDR5. Both use dual-channel memory buses. The AMD processor lists a memory bandwidth of 89.6 GB/s, while the Intel processor has no recorded memory bandwidth figure. PCIe connectivity also differs: AMD provides Gen 5 with 24 lanes (CPU only), while Intel provides Gen 5 with 16 lanes (CPU only). Integrated graphics differ as well, with AMD featuring Radeon Graphics and Intel featuring UHD Graphics 770.

The release dates place the AMD processor as the newer part, launching on 2025-10-06, while the Intel processor launched on 2024-01-07. Both carry active production status and unlocked multipliers. The AMD part number is 100-000001368E, and the Intel part number is SRMXG.

Fields that are the same include L1 cache at 80 KB per core, dual-channel memory bus, ECC memory support (both true), unlocked multipliers (both true), and active production status.

Where Each One Wins

The Intel Core i7-14700HX wins in every category where measured data exists, simply because the AMD Ryzen Embedded 9900X3D has no recorded benchmark results. The Intel part shows strength in multi-threaded workloads, with a Cinebench R23 multi-core score of 24595 and a PassMark multi-thread score of 36566. Its 20 cores and 28 threads provide a thread-count advantage over the AMD part's 12 cores and 24 threads. The Intel processor also demonstrates solid single-thread performance with a Cinebench R23 single-core score of 2103 and a PassMark single-thread score of 3947, matching the AMD part's 5.50 GHz boost clock despite a much lower 2.10 GHz base clock.

The AMD Ryzen Embedded 9900X3D wins on architectural specifications that suggest potential advantages in specific workloads. Its 128 MB of L3 cache dwarfs the Intel part's 33 MB, which historically benefits cache-sensitive applications such as certain scientific computing and data-heavy workloads. The AMD part also has a significantly higher base clock of 4.40 GHz versus 2.10 GHz, plus a higher TDP of 120 watts versus 55 watts, indicating it is designed for sustained performance in systems that can supply more power and cooling. The AMD processor's 89.6 GB/s memory bandwidth exceeds the Intel part's unrecorded figure, and its 24 PCIe Gen 5 lanes provide more expansion bandwidth than the Intel part's 16 lanes. The AMD part also uses a newer 4 nm process versus Intel's 10 nm, and it launched later.

The Verdict

The data supports different selections depending on the use case. The Intel Core i7-14700HX is the only one of the two with measured performance in the database, and those measurements place it at the 89th percentile among all CPUs with an average score of 45953. Its nearest rival cluster, all within 0.2%, includes the AMD EPYC 7303, AMD EPYC 4364P, AMD Ryzen AI 9 HX 375, and Intel Core Ultra 5 235. For anyone needing verified performance numbers, the Intel part is the only option with evidence backing it.

The AMD Ryzen Embedded 9900X3D offers a different specification profile: more L3 cache, higher base clock, higher TDP, newer process node, more PCIe lanes, and a desktop socket. Its 50th percentile ranking and zero average benchmark score reflect missing data, not measured inferiority. The 12-core, 24-thread configuration with 128 MB of L3 cache and 89.6 GB/s memory bandwidth suggests the AMD part targets workloads where cache capacity and memory throughput matter more than raw core count. The 120-watt TDP indicates a power envelope suited for embedded systems with adequate cooling, while the 55-watt Intel part fits mobile platforms with tighter thermal constraints.

The choice between them depends on whether the user prioritizes verified multi-threaded and single-threaded performance from the database, which favors the Intel Core i7-14700HX, or architectural features such as cache size, process efficiency, and PCIe lane count, which favor the AMD Ryzen Embedded 9900X3D. The Intel part's 20 cores and 28 threads give it a clear parallel workload advantage on paper. The AMD part's 5.50 GHz boost clock matches Intel's, and its 4.40 GHz base clock is more than double Intel's 2.10 GHz, which could translate to better sustained single-thread performance in the absence of measured data. Both processors support ECC memory, both have unlocked multipliers, and both are active in production. The database currently provides only one set of numbers, so the verdict rests on that evidence: the Intel Core i7-14700HX delivers recorded performance at the 89th percentile, while the AMD Ryzen Embedded 9900X3D remains an unmeasured specification sheet with strong theoretical attributes.
