Architecture Differences

The AMD Ryzen Embedded 9900X3D belongs to the 9000 series and uses the Granite Ridge codename, with a generation listed as Ryzen Embedded (Zen 5 (Granite Ridge)). It is fabricated on a 4 nm process at TSMC, with 16,630 million transistors across a die size of 2x 70.6 mm². The Intel Core i9-14900 belongs to the Core 14th Gen series and uses the Raptor Lake architecture with the Raptor Lake-R codename. Its generation is listed as Core i9 (Raptor Lake Refresh). Intel builds this chip on a 10 nm process at its own foundry, with a die size of 257 mm². No transistor count is recorded for the Intel part.

Cache hierarchies differ notably. Both processors have 80 KB of L1 cache per core and 1 MB of L2 cache per core on the AMD side, while the Intel part has 2 MB of L2 cache per core. The L3 cache is the largest distinction: 128 MB on the AMD processor versus 36 MB shared on the Intel processor. The AMD chip also uses an embedded processor positioning with the Zen 5 architecture, while the Intel chip uses the older Raptor Lake design.

Memory support diverges as well. The AMD part supports only DDR5, with a dual-channel bus and a recorded memory bandwidth of 89.6 GB/s. The Intel part supports both DDR4 and DDR5 over a dual-channel bus, with no bandwidth figure in the database. Both processors support ECC memory. PCI Express connectivity differs: the AMD processor provides Gen 5 with 24 lanes (CPU only), while the Intel processor provides Gen 5 with 16 lanes (CPU only). The AMD multiplier is unlocked, and the Intel multiplier is locked. The Intel part has a launch MSRP of $549.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark results between the AMD Ryzen Embedded 9900X3D and the Intel Core i9-14900. The AMD processor has no recorded benchmark scores, no average benchmark score, and no nearest rivals listed. The Intel processor has a full set of benchmark results across Cinebench, Geekbench, and Passmark tests.

The Intel Core i9-14900 records an average benchmark score of 58,115 and sits at the 92nd percentile among all CPUs. Its nearest rivals in the database are the Intel Xeon Platinum 8260M with an average score of 58,323 and a delta of -0.4%, the AMD Ryzen 7 9850X3D with 58,386 and a delta of -0.5%, the Intel Xeon w5-2545 with 58,504 and a delta of -0.7%, and the AMD EPYC 9015 with 57,555 and a delta of 1%. These deltas show the i9-14900 performing within roughly 1% of these four processors, indicating a tight cluster around its score.

Cinebench results for the Intel processor show strong multi-core performance. In Cinebench R15, it scores 4,793 multi-core and 315 single-core. In Cinebench R20, it scores 15,910 multi-core and 2,245 single-core. In Cinebench R23, it scores 31,070 multi-core and 2,212 single-core. The multi-core scores scale consistently with the core count of 24 cores and 32 threads.

Geekbench results for the Intel processor show 18,495 multi-core and 2,488 single-core. Passmark tests cover a broader range of workloads. The Intel processor scores 550,271 in data compression, 33,540 in data encryption, 30,624 in extended instructions, 188 in find prime numbers, 120,262 in floating point math, 175,010 in integer math, 44,578 in multithread, 2,486 in physics, 61,060 in random string sorting, and 4,323 in single thread.

The AMD Ryzen Embedded 9900X3D has no recorded scores in any of these tests, so no direct comparison is possible from the measured data. The database does not provide a basis for quantifying the AMD processor's performance relative to the Intel processor. The Intel chip's percentile rank of 92 and its average score of 58,115 are the only benchmark-derived figures available for this comparison.

The Verdict

The recorded data supports only a limited verdict. The Intel Core i9-14900 has a substantial set of benchmark measurements, placing it at the 92nd percentile with an average benchmark score of 58,115. Its nearest rivals all sit within 1% of its score, which indicates stable, competitive performance in the database's measurements.

The AMD Ryzen Embedded 9900X3D has no benchmark scores in the database, no average score, and no nearest rivals. Its percentile rank is 50, but this figure is recorded alongside an average benchmark score of 0, meaning it carries no measured performance weight. Any claim about the AMD processor's benchmark performance cannot be grounded in the available data.

The Intel processor also differs in architecture features: 24 cores versus 12, a 5.80 GHz boost clock versus 5.50 GHz, support for both DDR4 and DDR5, and a locked multiplier. The AMD processor offers 128 MB of L3 cache, a 4 nm process, an unlocked multiplier, and 24 PCIe Gen 5 lanes.

For users selecting strictly on measured benchmark data, the Intel Core i9-14900 is the only processor with recorded performance. For users prioritizing architectural features, the AMD processor's larger L3 cache, smaller process node, and unlocked multiplier are advantages, but none of these are quantified by benchmark scores in the database. The data does not permit a performance ranking between the two.

Where Each One Wins

The Intel Core i9-14900 wins in every measured benchmark category, because it is the only processor with recorded benchmark data. Its 24 cores and 32 threads support heavy multi-threaded workloads, and its Cinebench R23 multi-core score of 31,070 and Passmark multithread score of 44,578 reflect that capability. Its 5.80 GHz boost clock supports single-thread performance, with a Geekbench single-core score of 2,488 and a Passmark single thread score of 4,323. Its 92nd percentile rank places it above the large majority of all CPUs in the database.

The AMD Ryzen Embedded 9900X3D wins on architectural specifications without benchmark confirmation. Its 128 MB L3 cache is more than three times larger than the Intel chip's 36 MB, which can benefit cache-sensitive workloads. Its 4 nm process node indicates a denser, more modern manufacturing technology. Its unlocked multiplier allows overclocking, and its 24 PCIe Gen 5 lanes provide more CPU-attached PCIe connectivity than the Intel chip's 16 lanes. Its base clock of 4.40 GHz is much higher than the Intel chip's 2.00 GHz, though its boost clock of 5.50 GHz is lower.

In practical terms, the Intel part is the data-backed choice for known benchmark performance. The AMD part is the specification-backed choice for cache capacity, process technology, and overclocking flexibility, but its benchmark scores remain unrecorded. The database cannot confirm where the AMD processor wins in measured performance, so its advantages are limited to the architectural and feature differences listed above.
