AMD Ryzen Embedded 9900X3D vs Intel Core Ultra 3 105UL Comparison

Head-to-Head Benchmarks

The recorded data for this comparison is one-sided, as the AMD Ryzen Embedded 9900X3D has no benchmark entries in the database, while the Intel Core Ultra 3 105UL has a full suite of 17 recorded tests. This makes a direct head-to-head numerical comparison impossible for most workloads, but the Intel part's scores can be interpreted against its own nearest rivals to establish a performance baseline.

The Intel Core Ultra 3 105UL posts an average benchmark score of 13061, placing it in the 68th percentile among all CPUs in the database. Its closest rival, the Intel Core i5-9400F, scores 13041, a delta of 0.2%, meaning the Ultra 3 105UL is essentially tied with that older six-core desktop part. Against the Intel Core i7-10750H, the Ultra 3 105UL leads by 0.3%, with the rival scoring 13024. The Intel Core i5-8500 scores 13142, putting the Ultra 3 105UL 0.6% behind, and the Intel Core i7-7700K scores 13291, a 1.7% gap in the rival's favor.

Looking at specific workloads, the Intel Core Ultra 3 105UL delivers its strongest multi-threaded result in Cinebench R23, with a multicore score of 8742. Its single-core score in the same test is 1234. In Cinebench R20, the multicore score is 3671 and the single-core score is 518. The older Cinebench R15 test shows a multicore score of 881 and a single-core score of 124.

In PassMark suite tests, the Ultra 3 105UL scores 10285 in multithread and 3382 in single-thread. The data compression test records 93961, while data encryption scores 6354. Extended instructions score 5634, and floating point math scores 30750. Integer math posts 41171, and find prime numbers scores 44. Random string sorting scores 11179, and physics scores 718.

The AMD Ryzen Embedded 9900X3D, by contrast, has no recorded benchmark scores in the database. Its percentile versus all CPUs is listed at 50, and its average benchmark score is 0, which reflects the absence of test data rather than actual performance. Without any measured results, the database cannot establish where this processor sits relative to the Intel part or any other competitor.

The absence of data for the AMD chip is notable given its specifications. It carries 12 cores and 24 threads, a base clock of 4.40 GHz, and a boost clock of 5.50 GHz. The Intel part has 8 cores and 10 threads, with a base clock of 1.50 GHz and a boost clock of 4.20 GHz. The AMD chip also features 128 MB of L3 cache, versus 10 MB shared L3 cache on the Intel part. These specification differences suggest the AMD processor should be substantially faster in multi-threaded workloads, but the database contains no measurements to confirm or quantify that expectation.

For the Intel part, the nearest rival comparisons show a tightly clustered performance band. The four nearest rivals all fall within a narrow range of 13024 to 13291, and the Ultra 3 105UL's 13061 sits almost exactly in the middle. The largest delta among these rivals is the 1.7% gap to the Core i7-7700K, meaning the Ultra 3 105UL trails that older flagship by less than two percent. Conversely, its 0.3% lead over the Core i7-10750H shows that the newer Intel architecture provides only a marginal improvement over that mobile processor in the aggregate.

The Cinebench results reveal the character of the Intel part's performance. A multicore score of 8742 in Cinebench R23, against a single-core score of 1234, produces a ratio of roughly 7.1 to 1. That ratio indicates a processor with eight physical cores and two additional threads, where multi-threaded scaling is strong but not perfectly linear. The PassMark multithread score of 10285 versus a single-thread score of 3382 gives a ratio of about 3.0 to 1, reflecting the mixed workload nature of that suite.

The AMD Ryzen Embedded 9900X3D's specifications point to a much higher ceiling. Twelve cores with simultaneous multithreading produce 24 threads, and the 5.50 GHz boost clock is over a gigahertz higher than the Intel part's maximum. The 128 MB L3 cache is more than twelve times larger than the Intel chip's 10 MB. These figures suggest the AMD part would dominate in cache-sensitive and heavily parallel workloads, but no benchmark data exists to verify this.

The Verdict

The data supports a clear distinction between these two processors, but the verdict must be framed by what the database actually records. For the Intel Core Ultra 3 105UL, there is a complete benchmark profile showing a mid-pack desktop processor. Its average score of 13061 and 68th percentile ranking place it among established desktop and mobile parts from previous generations. The nearest rivals demonstrate that it trades blows with the Intel Core i5-9400F (0.2% ahead), the Intel Core i7-10750H (0.3% ahead), the Intel Core i5-8500 (0.6% behind), and the Intel Core i7-7700K (1.7% behind). This is a processor that delivers performance comparable to a six-core desktop CPU from a few generations ago, despite its 15 W TDP and 8-core, 10-thread configuration.

For the AMD Ryzen Embedded 9900X3D, the database contains no benchmark results. Its 50th percentile ranking and zero average score are artifacts of missing data, not indicators of performance. The specifications alone suggest a far more capable processor: 12 cores and 24 threads at up to 5.50 GHz, with 128 MB of L3 cache and DDR5 memory support. The Intel part cannot match those specifications on paper, but without measured results, the database cannot confirm how that translates into real-world scores.

The practical reading of the data is that the Intel Core Ultra 3 105UL is a verified quantity with a known performance envelope. It suits workloads that align with its modest core count and low power draw. The AMD Ryzen Embedded 9900X3D is an unmeasured quantity in the database, and any claim about its performance relative to the Intel part would be speculation, not analysis. Users seeking a processor with confirmed benchmark results can rely on the Intel data. Users considering the AMD part must wait for the database to record its performance before making a data-driven comparison.
