AMD Ryzen Embedded 9900X vs Intel Core Ultra 5 245KF Comparison

AMD Ryzen Embedded 9900X vs Intel Core Ultra 5 245KF

The Intel Core Ultra 5 245KF is the only processor in this comparison with recorded benchmark data, while the AMD Ryzen Embedded 9900X has no benchmark scores in the database. The Intel chip holds a 91st percentile rank among all CPUs, with an average benchmark score of 55,093. This places it ahead of the AMD Ryzen 9 9900X3D, which scores 54,762, a 0.6% difference in favor of the Intel part. The nearest rival data also shows the Intel Core Ultra 5 245KF trailing the Intel Core 7 253PQE by 1.5% and the Intel Core i9-14900HX by 1.6%, while leading the Intel Core Ultra 5 245K by 1.9%. The AMD Ryzen Embedded 9900X, by contrast, sits at the 50th percentile with an average benchmark score of 0, meaning no performance measurements exist for it in the database.

Head-to-Head Benchmarks

The database contains no head-to-head benchmark entries between the AMD Ryzen Embedded 9900X and the Intel Core Ultra 5 245KF. The Intel Core Ultra 5 245KF has a full set of Cinebench and PassMark results, while the AMD part has none. For the Intel chip, Cinebench R23 multicore performance reaches 36,647 points, and single-core performance reaches 5,173 points. In Cinebench R20, the multicore score is 15,391 and single-core is 2,172. The older Cinebench R15 test shows 3,693 multicore and 521 single-core. PassMark results for the Intel processor include a multithread score of 43,110, a single-thread score of 4,715, integer math at 98,854, floating point math at 131,546, and extended instructions at 37,912. Data compression scores 460,123, data encryption scores 33,381, find prime numbers scores 416, random string sorting scores 55,206, and physics scores 2,998. Without any AMD benchmark entries, a direct comparison of measured performance between the two chips is not possible from the recorded data. The Intel part's nearest rivals all have measured scores, and the 0.6% margin over the AMD Ryzen 9 9900X3D indicates the Intel Core Ultra 5 245KF performs essentially at parity with that AMD competitor. The 1.9% lead over the Intel Core Ultra 5 245K shows a small but consistent advantage within the same product family. Against the Intel Core 7 253PQE and Intel Core i9-14900HX, the 245KF trails by 1.5% and 1.6% respectively, placing it in a tight cluster of high-performance desktop and mobile parts.

Where Each One Wins

The Intel Core Ultra 5 245KF wins every benchmark category where data exists, simply because the AMD Ryzen Embedded 9900X has no recorded scores. The Intel chip's Cinebench R23 multicore score of 36,647 and single-core score of 5,173 establish it as a strong performer in both heavily threaded and lightly threaded workloads. PassMark results reinforce this: the multithread score of 43,110 and single-thread score of 4,715 show balanced capability across both workload types. The floating point math score of 131,546 significantly exceeds the integer math score of 98,854, indicating the Intel part handles floating point operations with particular strength. Data compression at 460,123 is the highest PassMark subtest score for this processor, suggesting strong performance in archiving and compression tasks. Data encryption at 33,381 and extended instructions at 37,912 are moderate scores, while find prime numbers at 416 and physics at 2,998 are lower relative to other subtests. The AMD Ryzen Embedded 9900X cannot be assigned wins in any category due to the absence of benchmark data. The Intel Core Ultra 5 245KF's 91st percentile rank versus the AMD chip's 50th percentile rank would suggest a wide performance gap, but this comparison is based on incomplete data for the AMD side. The AMD part does have architectural advantages that could matter in specific scenarios, but the database does not quantify them with benchmark scores.

The Verdict

The Intel Core Ultra 5 245KF is the only processor in this comparison with measured performance data. Its 91st percentile ranking, average benchmark score of 55,093, and narrow margins over its nearest rivals (0.6% ahead of the AMD Ryzen 9 9900X3D, 1.9% ahead of the Intel Core Ultra 5 245K, 1.5% behind the Intel Core 7 253PQE, and 1.6% behind the Intel Core i9-14900HX) establish it as a solid mid-to-high-range desktop processor. The AMD Ryzen Embedded 9900X has no benchmark scores, leaving its performance unquantified in the database. The AMD chip does offer architectural features that the Intel chip lacks: ECC memory support, a larger 64 MB L3 cache, 24 threads versus 14, integrated Radeon Graphics, and higher clock speeds of 4.40 GHz base and 5.60 GHz boost. The Intel chip counters with a smaller 3 nm process node, higher memory bandwidth of 102.4 GB/s, more physical cores at 14, and a 1.9% measured advantage over its direct sibling, the Intel Core Ultra 5 245K. The Intel part also has a recorded launch MSRP of $294, while the AMD part has no launch MSRP listed. For workloads where the database has measurements, the Intel Core Ultra 5 245KF is the verified performer. For users who require ECC memory, integrated graphics, or higher thread counts, the AMD Ryzen Embedded 9900X presents those capabilities on paper, but the database lacks the benchmark evidence to confirm how it performs in practice. The data supports choosing the Intel Core Ultra 5 245KF when measured performance is the deciding factor, and the AMD Ryzen Embedded 9900X only when its specific feature set, such as ECC support or integrated graphics, is a requirement that outweighs the lack of recorded benchmark results.
