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

The AMD Ryzen Embedded 9900X and Intel Core Ultra 5 225H serve different market segments, one a desktop-class embedded processor and the other a mobile-focused chip. The database contains benchmark results only for the Intel Core Ultra 5 225H, while the AMD Ryzen Embedded 9900X has no recorded benchmark scores, so the comparison relies on architectural specifications, cache configurations, and platform capabilities rather than direct performance measurements.

Where Each One Wins

The Intel Core Ultra 5 225H wins on measured performance, as the database records 19 benchmark scores for this processor. Its average benchmark score of 31,508 places it in the 82nd percentile of all CPUs, with nearest rivals including the Intel Core i5-13500 at 31,510, the AMD Ryzen 9 5980HX at 31,495, the Intel Core 7 240H at 31,483, and the Intel Core Ultra 3 205 at 31,473. These rivals are essentially tied, with delta percentages of 0 or 0.1, indicating the Ultra 5 225H sits in a competitive performance band.

The AMD Ryzen Embedded 9900X, by contrast, has no benchmark entries and an average score of zero, placing it in the 50th percentile. This does not indicate poor performance; rather, the database lacks recorded measurements for this processor. The Ryzen Embedded 9900X wins on specifications that favor high-throughput desktop workloads: 12 cores with 24 threads versus 14 cores with 14 threads on the Intel chip. The AMD part also delivers a base clock of 4.40 GHz and a boost clock of 5.60 GHz, compared to the Intel's 1.70 GHz base and 4.90 GHz boost. For single-threaded responsiveness and lightly threaded tasks, the AMD processor's higher clock speeds suggest an advantage, though no direct benchmark data confirms this.

The Intel Core Ultra 5 225H wins on power efficiency, with a TDP of 28 watts versus the AMD's 120 watts. This makes the Intel chip suitable for mobile and compact designs, as it is a mobile market segment processor on Intel BGA 2049 socket. The AMD Ryzen Embedded 9900X targets desktop systems with AMD Socket AM5 and a 120-watt TDP, which requires more substantial cooling but allows for sustained high-frequency operation.

Head-to-Head Benchmarks

Since the AMD Ryzen Embedded 9900X has no benchmark data, the head-to-head comparison is limited to the Intel Core Ultra 5 225H's recorded scores. The Intel chip's Cinebench R23 multicore score reaches 14,629.5, while its single-core score is 1,969. In Cinebench R20, the multicore score is 10,041 and single-core is 1,417. The Cinebench R15 scores are 2,397.5 for multicore and 288.5 for single-core. These results demonstrate strong multithreaded throughput for a 28-watt mobile processor, though the AMD Ryzen Embedded 9900X with 24 threads would likely score higher in heavily threaded workloads, assuming the higher TDP translates into sustained performance.

Geekbench scores for the Intel chip are 11,526 for multicore and 2,151 for single-core. The PassMark suite shows a multithread score of 28,119 and a single-thread score of 4,258. In specific PassMark tests, the Intel chip achieves 68,520 in integer math, 86,540 in floating-point math, 28,3451 in data compression, 21,428 in data encryption, 21,915 in extended instructions, 220 in find prime numbers, 1,877 in physics, and 33,654 in random string sorting. These figures provide a baseline for the Intel part's capabilities, but without AMD scores, no direct delta can be calculated.

The database records zero wins for either processor in head-to-head benchmarks, reflecting the absence of paired test data. The Intel chip's percentile rank of 82 places it above the 50th percentile of the AMD chip, but this percentile is based on the AMD's empty benchmark record, not actual performance. The nearest rival data for the Intel chip shows it is essentially tied with the Intel Core i5-13500 and AMD Ryzen 9 5980HX, which suggests the Ultra 5 225H delivers performance comparable to those established desktop and mobile processors.

Specification Differences

The two processors differ in nearly every core specification. The AMD Ryzen Embedded 9900X uses 12 cores and 24 threads, while the Intel Core Ultra 5 225H uses 14 cores and 14 threads. Base clocks are 4.40 GHz versus 1.70 GHz, and boost clocks are 5.60 GHz versus 4.90 GHz. The TDP differs substantially: 120 watts for the AMD chip versus 28 watts for the Intel chip. The AMD processor has an unlocked multiplier, allowing overclocking, while the Intel processor is locked.

Memory support differs as well. The AMD chip supports DDR5 only, while the Intel chip supports DDR5 and LPDDR5X. Both use dual-channel memory buses. Memory bandwidth is higher on the Intel chip at 102.4 GB/s, compared to 89.6 GB/s on the AMD chip. ECC memory is supported only on the AMD processor. PCIe lanes differ significantly: the AMD chip provides 24 Gen 5 lanes (CPU only), while the Intel chip provides 8 Gen 5 lanes (CPU only).

The integrated graphics differ, with the AMD chip featuring Radeon Graphics and the Intel chip featuring Arc Graphics 130T. The market segments also differ, with the AMD chip listed as desktop and the Intel chip as mobile. Release dates are distinct: the AMD processor launched on October 6, 2025, while the Intel processor launched on January 12, 2025.

Architecture Differences

The AMD Ryzen Embedded 9900X belongs to the 9000 series and uses the Granite Ridge codename with Zen 5 architecture, manufactured on a 4 nm process by TSMC. It contains 16,630 million transistors across a dual-die design with each die measuring 70.6 mm², totaling 2x 70.6 mm². The cache hierarchy includes 80 KB of L1 per core, 1 MB of L2 per core, and 64 MB of L3 cache. This large shared L3 cache benefits workloads with frequent data reuse across cores.

The Intel Core Ultra 5 225H belongs to the Core Ultra Series 2 and uses the Arrow Lake architecture with the Arrow Lake-H codename, manufactured on a 3 nm process by TSMC. The database lists no transistor count or die size for this chip. Its cache hierarchy includes 192 KB of L1 per core, 3 MB of L2 per core, and 18 MB of shared L3 cache. The larger per-core L1 and L2 caches on the Intel chip may improve per-thread performance, but the smaller L3 cache limits cross-core data sharing compared to the AMD chip's 64 MB.

The Intel chip supports two memory types (DDR5 and LPDDR5X) and has a higher memory bandwidth rating, which suits mobile platforms where power and memory flexibility matter. The AMD chip's higher TDP and desktop socket allow for higher sustained clocks, which is reflected in its 5.60 GHz boost versus the Intel's 4.90 GHz. The AMD chip also has more PCIe lanes, supporting more expansion devices, while the Intel chip's 8 lanes are typical for mobile designs with limited peripheral needs.

Both processors use TSMC as the foundry, though with different process nodes (4 nm for AMD, 3 nm for Intel). The smaller 3 nm node for the Intel chip likely contributes to its lower 28-watt TDP, while the AMD chip's 4 nm node with dual dies and higher clocks drives its 120-watt TDP. The AMD chip's generation is listed as Ryzen Embedded (Zen 5 (Granite Ridge)), and its part number is 100-000000662E. The Intel chip's generation is Ultra 5 (Arrow Lake-H), and its part number is SRQAM.

The Verdict

From the recorded data, the Intel Core Ultra 5 225H is the only processor with measurable performance, scoring 31,508 on average and ranking in the 82nd percentile. Its benchmark results show competitive multithreaded performance in Cinebench R23 (14,629.5) and Geekbench multicore (11,526), placing it alongside the Intel Core i5-13500 and AMD Ryzen 9 5980HX in the nearest rival group. Users who need a mobile processor with a 28-watt TDP, support for DDR5 and LPDDR5X, and Arc Graphics 130T should consider the Intel chip.

The AMD Ryzen Embedded 9900X, despite lacking benchmark scores, offers specifications that appeal to desktop embedded workloads. Its 12 cores and 24 threads, 5.60 GHz boost clock, 64 MB L3 cache, and ECC memory support indicate a processor designed for high-throughput computing with data integrity requirements. The 120-watt TDP and 24 PCIe Gen 5 lanes suggest it can power substantial expansion and sustained compute tasks. The unlocked multiplier allows tuning for specific performance targets.

Given the absence of AMD benchmark data, the database cannot confirm which processor is faster in practice. Based on specifications, the AMD chip should excel in heavily threaded applications due to its 24 threads and high boost clock, while the Intel chip should win on power efficiency and memory bandwidth. The choice depends on the platform: the AMD chip fits desktop AM5 systems with ECC needs, while the Intel chip fits mobile BGA 2049 designs with lower power constraints. The Intel chip's measured scores provide a reference point, but the AMD chip's potential remains unquantified in the database.
