AMD Ryzen Embedded 9900X3D vs Intel Core 5 120U Comparison

Head-to-Head Benchmarks

The Intel Core 5 120U is the only processor in this comparison with recorded benchmark data. The AMD Ryzen Embedded 9900X3D has no benchmark scores in the database, so all quantitative comparisons must rely on the Intel part's measured performance and its position among rival processors.

The Intel Core 5 120U delivers a multi-threaded Cinebench R23 score of 6659 and a single-core score of 1756.5. In Geekbench, it records 5888 for multi-core and 1727 for single-core. The Passmark suite shows a multithread score of 15042 and a single-thread score of 3479. These numbers place the processor at the 72nd percentile among all CPUs in the database, with an average benchmark score of 17898.

The nearest rivals for the Intel Core 5 120U provide context. The AMD Ryzen 5 3600XT scores 17891, a delta of 0 percent. The Intel Core 5 221TE scores 17860, a delta of 0.2 percent. The AMD Ryzen 5 1600 scores 17994, a delta of -0.5 percent. The Intel Core 7 350 scores 17779, a delta of 0.7 percent. The data confirms the Core 5 120U sits within a tight cluster of mid-range processors, neither dominating nor trailing its direct competitors by a meaningful margin.

With no head-to-head benchmark entries and no wins recorded for either processor, the database contains no direct comparison points between the AMD Ryzen Embedded 9900X3D and the Intel Core 5 120U. The AMD part's percentile stands at 50, and its average benchmark score is 0, indicating an absence of measured results. The analysis must therefore treat the AMD processor's performance characteristics as unquantified in the current dataset.

Architecture Differences

The AMD Ryzen Embedded 9900X3D belongs to the 9000 series and uses the Granite Ridge codename, built on a Zen 5 (Granite Ridge) generation. It is fabricated on a 4 nm process at TSMC, with 16,630 million transistors and a die size of 2x 70.6 mm². The processor uses the AMD Socket AM5 and targets the desktop market segment. Its integrated graphics are Radeon Graphics. The multiplier is unlocked, and the part number is 100-000001368E.

The Intel Core 5 120U uses the Raptor Lake architecture with the Raptor Lake-U codename, belonging to the Core 5 generation. It is fabricated on a 10 nm process at Intel, with no transistor count or die size recorded. The processor uses the Intel BGA 1744 socket and targets the mobile market segment. Its integrated graphics are Iris Xe Graphics 80EU. The multiplier is locked, and the part number is SRM7P.

Memory support differs substantially. The AMD processor supports DDR5 with dual-channel memory bus and a memory bandwidth of 89.6 GB/s. The Intel processor supports both DDR4 and DDR5 with dual-channel memory bus, but no memory bandwidth figure is recorded. ECC memory is available on the AMD part but not on the Intel part.

The cache hierarchy also diverges. The AMD processor has 1 MB of L2 per core and 128 MB of L3. The Intel processor has 1.25 MB of L2 per core and 12 MB of shared L3. Both share the same 80 KB L1 per core figure. The AMD part's L3 cache is more than ten times larger than the Intel part's L3 cache.

Process node and foundry represent another clear separation: TSMC's 4 nm process for AMD versus Intel's 10 nm process for the 120U. The AMD part uses a chiplet design with two 70.6 mm² dies, while the Intel part has no die size recorded.

The Verdict

The data shows two processors aimed at different market segments with very different design priorities. The AMD Ryzen Embedded 9900X3D targets desktop systems with a 120 TDP, 12 cores, 24 threads, DDR5 memory support, ECC capability, PCIe Gen 5 with 24 lanes, and an unlocked multiplier. The Intel Core 5 120U targets mobile systems with a 15 TDP, 10 cores, 12 threads, DDR4 and DDR5 support, no ECC, PCIe Gen 4 with 8 lanes, and a locked multiplier.

The Intel Core 5 120U has recorded benchmark data, placing it at the 72nd percentile with an average score of 17898. Its nearest rivals show it performs within 0.7 percent of the Intel Core 7 350, within 0.2 percent of the Intel Core 5 221TE, and within 0.5 percent of the AMD Ryzen 5 1600. The AMD Ryzen Embedded 9900X3D has no benchmark scores, so its relative performance cannot be assessed from the database.

For users requiring ECC memory, PCIe Gen 5 connectivity, a large L3 cache, and high core counts with simultaneous multi-threading, the AMD part offers those features in a desktop form factor. For users prioritizing low power consumption and a mobile platform, the Intel part provides measured performance at a fraction of the TDP. The absence of AMD benchmark data prevents any direct performance verdict between the two.

Where Each One Wins

The Intel Core 5 120U wins in measured benchmark presence. It has 19 recorded benchmark scores across Cinebench R15, R20, R23, Geekbench, and Passmark tests. The data shows its strongest multi-threaded result in Cinebench R23 at 6659 and its strongest single-thread result in Passmark at 3479. Its percentile rank of 72 confirms it performs above the median CPU in the database.

The AMD Ryzen Embedded 9900X3D wins in raw specification features. It offers more cores, more threads, higher clocks, a larger L3 cache, ECC support, PCIe Gen 5, and an unlocked multiplier. Its 128 MB L3 cache is a substantial advantage for workloads that benefit from large cache capacity. Its 89.6 GB/s memory bandwidth is recorded, whereas the Intel part has no bandwidth figure. The AMD part's desktop orientation with an active production status indicates availability for socketed systems.

For mobile deployments where power efficiency matters, the Intel part's 15 TDP versus the AMD part's 120 TDP represents a decisive difference. The Intel processor also supports both DDR4 and DDR5, offering memory flexibility that the AMD part lacks.

For desktop systems requiring server-class features like ECC, high lane-count PCIe Gen 5, and large caches, the AMD part holds the advantage. The data cannot assign a performance win to either processor because the AMD part has no benchmark scores. The only measurable performance data belongs to the Intel Core 5 120U, which demonstrates competitive standing among its nearest rivals.
