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

Head-to-Head Benchmarks

The database records no head-to-head benchmark results for the AMD Ryzen Embedded 9900X and the Intel Core Ultra 5 225. The AMD part has an empty benchmarks array, meaning no measured scores exist for it in the database. The Intel part, by contrast, has a full suite of 17 recorded benchmark scores. This asymmetry shapes the entire comparison: the only quantitative performance data available belongs to the Intel Core Ultra 5 225.

The Intel 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 yields 2,609 multi-core and 368 single-core. These numbers establish a clear baseline for Intel's 10-core, 10-thread part.

PassMark results for the Intel chip show a multi-thread score of 30,459 and a single-thread score of 4,412. The database also records specific workload scores: data compression at 302,811, data encryption at 22,285, extended instructions at 27,162, prime number finding at 358, floating point math at 92,038, integer math at 65,345, physics at 2,342, and random string sorting at 36,590.

Because the AMD Ryzen Embedded 9900X has no recorded benchmarks, the database cannot produce a win count for either processor. The winsA and winsB fields are both zero. Any comparison of raw performance between the two parts is impossible from the recorded data alone. The AMD processor's percentile ranking sits at 50, while the Intel chip ranks at 85. The Intel part's average benchmark score is 36,938, placing it near the AMD Ryzen 5 5600F (36,945, 0% delta), AMD Ryzen 5 5500X3D (37,018, -0.2% delta), AMD Ryzen AI 7 PRO 450 (37,093, -0.4% delta), and Intel Core i9-12900T (37,112, -0.5% delta). These nearest rivals all cluster within half a percent of the Intel Core Ultra 5 225, indicating the Intel chip sits at the center of a tight performance group.

The absence of AMD benchmark data means no statements about relative performance can be made. The database records specifications for both processors, but performance measurements exist for only one. This is a fundamental limitation of the current dataset.

Architecture Differences

The two processors come from different architectural lineages. The AMD Ryzen Embedded 9900X uses the Granite Ridge codename, built on the Zen 5 architecture within the 9000 series. The Intel Core Ultra 5 225 uses the Arrow Lake-S codename, built on the Arrow Lake architecture within the Core Ultra Series 2.

Manufacturing processes differ. AMD uses a 4 nm process from TSMC, while Intel uses a 3 nm process, also from TSMC. Transistor counts are close: AMD integrates 16,630 million transistors across a dual-die design measuring 2x 70.6 mm², while Intel integrates 17,800 million transistors on a single die measuring 243 mm². The Intel die is substantially larger in area but houses more transistors.

Cache hierarchies diverge significantly. AMD allocates 80 KB of L1 cache per core and 1 MB of L2 cache per core, with a 64 MB L3 cache. Intel allocates 192 KB of L1 cache per core and 3 MB of L2 cache per core, with a 20 MB shared L3 cache. Intel's per-core L1 and L2 allocations are larger, but AMD's total L3 cache is 44 MB larger.

Memory support is DDR5 for both processors, with dual-channel memory buses. The Intel part achieves higher memory bandwidth at 102.4 GB/s versus AMD's 89.6 GB/s. ECC memory support exists only on the AMD side, which aligns with the "Embedded" designation in its name.

PCIe connectivity differs. AMD provides Gen 5 with 24 lanes (CPU only), while Intel provides Gen 5 with 20 lanes (CPU only). AMD has four additional PCIe lanes.

Integrated graphics differ. AMD includes Radeon Graphics, while Intel includes Arc Xe-LPG Graphics with 16 execution units. No performance data for either integrated GPU is recorded in the database.

The AMD processor has an unlocked multiplier, a trait associated with overclocking flexibility. The Intel processor has a locked multiplier. The AMD part is part of the Ryzen Embedded product line, which typically targets industrial or always-on applications. The Intel part targets the desktop market segment.

Both processors support DDR5 memory with dual-channel buses. Both are active production parts for the desktop market segment. Both use TSMC as the foundry. These shared traits do not offset the differences in core counts, clocks, cache, TDP, and feature support.

The release dates differ by nine months. Intel launched on 2025-01-06, while AMD launched on 2025-10-06. The Intel part has a recorded launch MSRP of $246, while the AMD part has no recorded launch MSRP.

The Verdict

The database currently provides no benchmark scores for the AMD Ryzen Embedded 9900X. Every performance number in this analysis belongs to the Intel Core Ultra 5 225. The AMD processor's percentile rank of 50 versus Intel's 85 suggests the Intel part sits higher in the overall distribution of all CPUs, but this percentile is computed from an empty benchmark set for AMD, making the comparison unreliable.

The Intel Core Ultra 5 225 has an average benchmark score of 36,938 and sits within 0.5% of four nearest rivals: the AMD Ryzen 5 5600F, AMD Ryzen 5 5500X3D, AMD Ryzen AI 7 PRO 450, and Intel Core i9-12900T. This position indicates the Intel chip performs consistently with a known group of mid-range processors. No analogous data exists for the AMD Ryzen Embedded 9900X.

Specifications favor AMD in several areas: more cores, more threads, higher clocks, more L3 cache, ECC support, more PCIe lanes, and an unlocked multiplier. Specifications favor Intel in others: a smaller process node, more transistors, larger per-core L1 and L2 caches, higher memory bandwidth, and a lower TDP of 65 W versus AMD's 120 W.

Without recorded performance data for the AMD part, any verdict on relative speed is unsupported. The data allows a verdict only on features. Users requiring ECC memory or 24 threads should consider the AMD part based on its specification sheet. Users requiring a locked, lower-TDP processor with higher memory bandwidth should consider the Intel part. The Intel part's recorded benchmarks confirm it performs within a tight cluster of established processors, while the AMD part's performance remains unmeasured.

Where Each One Wins

The Intel Core Ultra 5 225 wins in every measured benchmark category, solely because it is the only processor with recorded scores. Its Cinebench R23 multi-core score of 25,891 and single-core score of 3,655 represent the only quantitative performance data in the comparison. PassMark scores for compression, encryption, extended instructions, prime finding, floating point math, integer math, multi-thread, physics, random string sorting, and single-thread all belong to Intel.

The AMD Ryzen Embedded 9900X wins in specification-based categories. It offers 12 cores versus 10, 24 threads versus 10, a base clock 1.10 GHz higher, and a boost clock 0.70 GHz higher. Its 64 MB L3 cache dwarfs Intel's 20 MB. ECC memory support and a 24-lane Gen 5 PCIe implementation exceed Intel's 20-lane implementation. The unlocked multiplier offers overclocking flexibility that Intel's locked multiplier does not.

The TDP split favors Intel. Intel's 65 W TDP is nearly half of AMD's 120 W, suggesting lower power draw under sustained loads. Memory bandwidth favors Intel by 12.8 GB/s. The smaller 3 nm process node and higher transistor count suggest Intel's design is more densely integrated, though this does not translate to a measured performance advantage without AMD benchmark data.

The release timeline favors Intel, which launched on 2025-01-06, nine months before AMD's 2025-10-06 launch. The Intel part carries a launch MSRP of $246, while the AMD part has no recorded price. The AMD part's market segment is Desktop despite the "Embedded" branding, and its production status is Active, matching Intel's Active status.

The database cannot award a performance win to either processor because only one has data. The specification sheet awards AMD wins in core count, thread count, clocks, L3 cache, ECC, PCIe lanes, and overclocking. The specification sheet awards Intel wins in process node, transistor count, per-core L1/L2 cache, memory bandwidth, TDP, and integrated graphics execution units (16 EU versus unspecified Radeon Graphics). The measured data awards Intel wins in all 17 recorded benchmarks, but these are uncontested.
