AMD Ryzen Embedded 9900X3D vs Intel Core Ultra 5 225 Comparison

Head-to-Head Benchmarks

The Intel Core Ultra 5 225 is the only processor in this comparison with recorded benchmark data. The AMD Ryzen Embedded 9900X3D has no benchmark entries in the database, so direct numerical comparisons cannot be made from the available measurements. What the data does show is where the Intel part stands in absolute terms.

The Core Ultra 5 225 delivers a Cinebench R23 multi-core score of 25,891 and a single-core score of 3,655. In Cinebench R20, it scores 6,317 multi-core and 891 single-core. The older Cinebench R15 run produces 2,609 multi-core and 368 single-core. PassMark results show 30,459 in multithread, 4,412 in single-thread, 92,038 in floating point math, and 65,345 in integer math. Data compression reaches 302,811, while data encryption scores 22,285. Extended instructions hit 27,162, and random string sorting finishes at 36,590. Physics processing scores 2,342, and the find prime numbers test yields 358.

The Core Ultra 5 225 holds an average benchmark score of 36,938, placing it at the 85th percentile among all CPUs in the database. Its nearest rivals cluster tightly around that average. The AMD Ryzen 5 5600F scores 36,945, essentially identical with a 0 percent delta. The AMD Ryzen 5 5500X3D trails by 0.2 percent at 37,018. The AMD Ryzen AI 7 PRO 450 sits 0.4 percent behind at 37,093, and the Intel Core i9-12900T is 0.5 percent lower at 37,112. These sub-one-percent gaps indicate the Core Ultra 5 225 performs within a narrow band of well-known desktop and mobile parts.

Because the AMD Ryzen Embedded 9900X3D has no benchmark scores recorded, there is no head-to-head win count for either side. The database shows zero wins for each processor in their direct comparison. All quantitative analysis must therefore focus on the Intel part's standalone performance and its position relative to other CPUs in the database.

Where Each One Wins

Without recorded benchmarks for the AMD Ryzen Embedded 9900X3D, a benchmark-based use-case split cannot be established from measurements. The available data only defines the Intel Core Ultra 5 225's strengths.

The Core Ultra 5 225 shows strong multi-threaded capability through its Cinebench R23 multi-core score of 25,891, which is roughly seven times its single-core result of 3,655. This ratio suggests the processor scales well across all 10 cores. PassMark multithread at 30,459 versus single-thread at 4,412 reinforces that pattern. Workloads that use all cores, such as rendering, compilation, or batch processing, benefit from this scaling.

Single-thread performance is also solid. The Cinebench R15 single-core score of 368 and R20 single-core of 891 indicate responsive per-core execution. Applications that rely on one or two threads, like many games or legacy software, will see consistent results. The PassMark single-thread score of 4,412 confirms this.

The specialized PassMark tests reveal additional strengths. Floating point math at 92,038 is notably higher than integer math at 65,345, which points to strong vector and scientific computing throughput. Data compression at 302,811 is the highest single sub-test score, indicating efficient memory and cache handling for compression workloads. Data encryption at 22,285 and extended instructions at 27,162 show capable but not exceptional cryptographic and SIMD performance. Random string sorting at 36,590 suggests solid memory subsystem behavior for data organization tasks.

The architecture differences between the two processors mean each has distinct theoretical advantages. The AMD part's larger L3 cache and higher core count could favor cache-sensitive workloads, while the Intel part's higher memory bandwidth could favor streaming tasks. But without AMD benchmark data, these remain structural observations rather than measured outcomes.

Architecture Differences

The AMD Ryzen Embedded 9900X3D uses the Granite Ridge codename, part of the Ryzen Embedded generation built on Zen 5 architecture. It is manufactured on a 4 nm process at TSMC, containing 16,630 million transistors across a dual-die design with each die measuring 70.6 mm². The Intel Core Ultra 5 225 uses the Arrow Lake-S codename, part of the Core Ultra Series 2 generation built on Arrow Lake architecture. It is manufactured on a 3 nm process at TSMC, containing 17,800 million transistors on a single 243 mm² die.

Core and thread counts differ significantly. The AMD processor has 12 cores and 24 threads, leveraging simultaneous multithreading. The Intel processor has 10 cores and 10 threads, with no hyper-threading support. The AMD part's base clock is 4.40 GHz with a boost clock of 5.50 GHz. The Intel part runs at a 3.30 GHz base and 4.90 GHz boost. The AMD part has an unlocked multiplier, while the Intel part is locked.

Cache hierarchies diverge sharply. The AMD processor provides 80 KB of L1 cache per core, 1 MB of L2 per core, and a massive 128 MB of L3 cache. The Intel processor provides 192 KB of L1 per core, 3 MB of L2 per core, and 20 MB of shared L3. The AMD part's 128 MB L3 is six times larger than Intel's 20 MB, which typically benefits workloads with large working sets that fit in cache.

Memory support shows both use DDR5 with dual-channel memory buses. The AMD part has 89.6 GB/s memory bandwidth, while the Intel part reaches 102.4 GB/s, a 14 percent advantage. The AMD processor supports ECC memory, while the Intel processor does not. PCIe connectivity also differs: AMD provides Gen 5 with 24 lanes from the CPU, while Intel provides Gen 5 with 20 lanes.

Integrated graphics differ as well. The AMD processor includes Radeon Graphics, while the Intel processor includes Arc Xe-LPG Graphics with 16 execution units. Thermal design power favors Intel: the Core Ultra 5 225 is rated at 65 watts, while the Ryzen Embedded 9900X3D is rated at 120 watts. The AMD part targets the desktop market segment with an Active production status and a release date of October 6, 2025. The Intel part also targets desktop, released January 6, 2025, with an Active status.

The Verdict

The recorded data offers only one side of this comparison. The Intel Core Ultra 5 225 has a full set of benchmark results and a clear performance profile. It sits at the 85th percentile with an average score of 36,938, effectively matching the AMD Ryzen 5 5600F and edging out the Ryzen 5 5500X3D by 0.2 percent. Its Cinebench R23 multi-core score of 25,891 and single-core score of 3,655 show balanced capability. The 10-core, 10-thread configuration with a 65 watt TDP makes it a power-efficient desktop option. Its 3 nm process and 102.4 GB/s memory bandwidth support strong throughput.

The AMD Ryzen Embedded 9900X3D has no benchmark scores in the database, so its measured performance cannot be stated. What the data does show is a structural advantage: 12 cores, 24 threads, a 128 MB L3 cache, and a 5.50 GHz boost clock. These specifications suggest high multi-threaded potential and cache-sensitive workload benefits. The 120 watt TDP and dual-die 4 nm design indicate a more power-hungry part. ECC memory support and 24 PCIe Gen 5 lanes position it for embedded and workstation use cases.

Users who need verified performance data today should look to the Core Ultra 5 225, as its benchmark results are recorded and its percentile ranking is established. Users who require ECC memory, more PCIe lanes, or a much larger L3 cache may prefer the Ryzen Embedded part based on its specifications. The data does not allow a measured performance verdict between the two, only a specification-based one.
