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

Where Each One Wins

The recorded benchmark data for this comparison is one-sided. The Intel Core Ultra 5 225T is the only processor in this pair with benchmark entries in the database. It holds scores across Cinebench R15, R20, R23, and Passmark tests, covering both single-thread and multi-thread workloads. The AMD Ryzen Embedded 9900X has no benchmark results listed, so every measurable performance indicator in this comparison comes from the Intel part.

Because the AMD processor lacks recorded scores, the use-case split is defined entirely by what the Intel Core Ultra 5 225T can demonstrate. In Cinebench R23, it delivers a multi-core score of 21971 and a single-core score of 3101. Those two numbers indicate that the chip is capable in both heavily threaded rendering tasks and lightly threaded responsiveness. The R20 results follow the same pattern: 9227 multi-core and 1302 single-core. The R15 results show 2214 multi-core and 312 single-core.

The Passmark suite adds more granularity. The highest absolute score for the Intel part is in data compression at 233998. Data encryption reaches 18289, extended instructions hit 20083, floating point math reaches 82751, and integer math lands at 59543. Random string sorting produces 28774. The multi-thread Passmark score is 25358, while the single-thread score is 4348. Physics tests return 2053, and the find prime numbers test returns 284.

The AMD Ryzen Embedded 9900X, by contrast, has no wins because it has no entries. The wins count in the database is 0 for AMD and 0 for Intel in head-to-head benchmarks, but the available data places all measurable performance on the Intel side. Any workload classification for the AMD chip would require inference from its specifications, which the database does not support with recorded scores.

Architecture Differences

The two processors diverge at the fundamental design level. The AMD Ryzen Embedded 9900X belongs to the 9000 series and the Ryzen Embedded generation built on Zen 5 (Granite Ridge). Its process node is 4 nm, fabricated by TSMC. The Intel Core Ultra 5 225T belongs to the Core Ultra Series 2, uses Arrow Lake architecture on the Arrow Lake-S codename, and is built on a 3 nm process, also from TSMC.

Transistor counts differ. The AMD part contains 16,630 million transistors across a die size of 2x 70.6 mm². The Intel part contains 17,800 million transistors on a single 243 mm² die. The Intel chip has more transistors overall, but the AMD chip uses a chiplet-style dual-die layout.

Core and thread counts create a clear separation. The AMD processor provides 12 cores and 24 threads. The Intel processor provides 10 cores and 10 threads, meaning it has no hyper-threading equivalent. That is a 12-core, 24-thread design versus a 10-core, 10-thread design. The AMD part also has a higher base clock of 4.40 GHz and a higher boost clock of 5.60 GHz, compared to the Intel base of 2.50 GHz and boost of 4.90 GHz.

Cache hierarchies differ substantially. The AMD chip uses 80 KB of L1 per core, 1 MB of L2 per core, and 64 MB of L3. The Intel chip uses 192 KB of L1 per core, 3 MB of L2 per core, and 20 MB of shared L3. The AMD processor offers far more total L3 cache, while the Intel processor provides more L1 and L2 per core.

Power envelopes also separate the two. The AMD Ryzen Embedded 9900X has a TDP of 120 watts. The Intel Core Ultra 5 225T has a TDP of 65 watts. Socket compatibility differs as well: AMD uses Socket AM5, Intel uses Socket 1851. The AMD chip has an unlocked multiplier; the Intel chip does not.

Memory support shows both similarities and differences. Both support DDR5 and dual-channel memory. The AMD processor offers ECC memory support, while the Intel processor does not. Memory bandwidth is higher on the Intel side at 102.4 GB/s, compared to 89.6 GB/s for the AMD chip. PCIe connectivity also differs: AMD provides Gen 5 with 24 lanes (CPU only), while Intel provides Gen 5 with 20 lanes (CPU only).

Integrated graphics differ. The AMD processor uses Radeon Graphics. The Intel processor uses Arc Xe-LPG Graphics 16EU. The AMD part was released on 2025-10-06, while the Intel part was released on 2024-12-31. Both are listed as active production parts.

The Verdict

The database presents an asymmetric picture. The Intel Core Ultra 5 225T has a percentile rank of 82 against all CPUs and an average benchmark score of 30468. Its nearest rivals reinforce its standing: the Intel Core i9-11980HK scores 30422 with a delta of 0.2%, the AMD Ryzen 5 7640HS scores 30390 with a delta of 0.3%, the Intel Core i5-13600H scores 30548 with a delta of -0.3%, and the AMD Ryzen 7 7736U scores 30364 with a delta of 0.3%. This places the Intel chip in a cluster of capable mobile and desktop processors, performing within a fraction of a percent of each rival.

The AMD Ryzen Embedded 9900X has a percentile rank of 50 and an average benchmark score of 0, with no rivals listed and no benchmarks recorded. The data cannot support a performance verdict for the AMD part. What the data does show is that the Intel part has measurable, competitive scores across rendering and math workloads, while the AMD part exists in the database without any performance measurements.

From the recorded data alone, the Intel Core Ultra 5 225T is the only processor in this comparison with demonstrated benchmark performance. Its 82nd percentile ranking indicates it sits above the median CPU in the database. The AMD Ryzen Embedded 9900X, with a 50th percentile and no scores, cannot be positioned relative to the Intel chip or to any other processor. Selection between the two would depend entirely on the unmeasured characteristics of the AMD chip, which the database does not cover.

Head-to-Head Benchmarks

The head-to-head benchmark list between these two processors is empty. No direct comparison entries exist in the database. The only benchmark data available belongs to the Intel Core Ultra 5 225T.

In Cinebench R23, the Intel chip scores 21971 multi-core and 3101 single-core. The multi-core figure indicates strong parallel performance for rendering workloads. The single-core figure indicates solid responsiveness for tasks that depend on one thread. In Cinebench R20, the scores are 9227 multi-core and 1302 single-core, following the same relative pattern. In Cinebench R15, the scores are 2214 multi-core and 312 single-core.

The Passmark results expand the picture. Data compression at 233998 is the highest recorded score for the Intel part, showing particular strength in compression workloads. Floating point math at 82751 and integer math at 59543 both indicate robust arithmetic throughput. Data encryption at 18289 and extended instructions at 20083 cover security and specialized instruction workloads. Random string sorting at 28774 shows sorting efficiency. The multi-thread Passmark score of 25358 aligns with the multi-core Cinebench results, while the single-thread score of 4348 aligns with the single-core Cinebench results. Physics at 2053 and find prime numbers at 284 round out the measured workloads.

The AMD Ryzen Embedded 9900X has no recorded scores in any of these tests. Its wins count in the database is 0, and the Intel part also shows 0 wins in the head-to-head field, but that field is empty. The practical result is that every benchmark number in this comparison belongs to the Intel Core Ultra 5 225T, and that processor's scores place it within 0.3% of several established competitors in its nearest rivals list.
