AMD Ryzen Embedded 9900X vs Intel Core i5-14450HX Comparison

Head-to-Head Benchmarks

The recorded data for this comparison is asymmetric. The AMD Ryzen Embedded 9900X has no individual benchmark entries in the database, showing an average benchmark score of 0 and a percentile rank of 50 among all CPUs. The Intel Core i5-14450HX, by contrast, carries a full suite of Cinebench and PassMark results, with an average benchmark score of 32040 and a percentile rank of 82. This means the direct head-to-head comparison is limited to what the database has measured for the Intel part, while the AMD part must be assessed through its architectural specifications and standing in the overall distribution.

The Intel Core i5-14450HX delivers a Cinebench R23 multi-core score of 20108 and a single-core score of 2838. In Cinebench R20, it posts 8445 multi-core and 1191 single-core. The R15 results show 2026 multi-core and 285 single-core. These numbers place the chip firmly in the upper tier of the database. Its percentile rank of 82 means it outperforms roughly eight out of every ten CPUs in the recorded population. The nearest rivals confirm this position. The Intel Core i7-13705H sits just 0.1% behind with an average score of 32076, the Intel Core i5-14400 is 0.2% behind at 32115, the Intel Core i7-12800H is 0.3% behind at 32121, and the Intel Core i9-11900 trails by 0.6% with 32226. The data indicates that the i5-14450HX is effectively at parity with these four chips, with deltas under one percent in every case.

In PassMark tests, the Intel part shows a multi-thread score of 23680 and a single-thread score of 3643. Integer math reaches 78330, floating point math reaches 58037, and extended instructions hit 17207. Data compression scores 278538, data encryption 15574, and random string sorting 29565. The find prime numbers test returns 98, and the physics test returns 1475. These figures provide a broad picture of the chip's compute characteristics across different workload types.

The AMD Ryzen Embedded 9900X, lacking recorded benchmark scores, cannot be placed against the Intel chip in any individual test within this database. Its percentile rank of 50 suggests it sits at the median of all CPUs in the database, which is far below the Intel part's 82nd percentile. However, the AMD processor carries 12 cores and 24 threads, compared to the Intel chip's 10 cores and 16 threads. The AMD part also boosts to 5.60 GHz versus 4.80 GHz for the Intel part, and its base clock of 4.40 GHz is substantially higher than the Intel chip's 2.40 GHz. These specifications indicate a strong theoretical advantage for the AMD part in multi-threaded and frequency-sensitive workloads, even though the database does not currently contain direct measurements to confirm it.

Where Each One Wins

Based strictly on available data, the Intel Core i5-14450HX wins every measured benchmark category because it is the only chip with recorded results. Its Cinebench R23 multi-core score of 20108 and single-core score of 2838 demonstrate balanced performance across both heavily threaded and lightly threaded applications. The PassMark integer math score of 78330 and floating point math score of 58037 indicate strength in general-purpose compute. Data compression at 278538 suggests solid performance in archiving and storage-related tasks. The encryption score of 15574 and extended instructions score of 17207 point to capable handling of cryptographic and SIMD workloads.

The AMD Ryzen Embedded 9900X cannot claim any measured win in this database, but its specification sheet suggests where it would likely excel. Twelve cores and 24 threads give it a 20% core advantage and a 50% thread advantage over the Intel part. The 5.60 GHz boost clock outpaces the Intel chip's 4.80 GHz by a significant margin. The 64 MB L3 cache dwarfs the Intel chip's 20 MB shared L3, which would benefit workloads with large working sets. The AMD part also supports DDR5 memory with 89.6 GB/s of bandwidth, while the Intel chip supports both DDR4 and DDR5 but has no recorded bandwidth figure in the database. The AMD chip's 120 W TDP, however, is more than double the Intel chip's 55 W TDP, indicating a much higher power envelope for that performance potential.

The Intel chip's 10 nm process node and 257 mm² die size contrast with the AMD chip's 4 nm node built at TSMC with a 2x 70.6 mm² die configuration. The AMD part's smaller and more advanced process suggests better transistor density and potentially better efficiency per clock, though the higher TDP tells a different story at the package level. The Intel chip's 16 PCIe Gen 5 lanes are fewer than the AMD chip's 24 PCIe Gen 5 lanes, giving the AMD part more headroom for expansion devices.

The Verdict

The data supports two distinct use cases. For users who require verified performance measurements today, the Intel Core i5-14450HX is the only option with recorded scores in the database. Its 82nd percentile ranking and average benchmark score of 32040 place it among capable performers, with nearest rivals all within 0.6% of its score. The chip's 10 cores, 16 threads, and 4.80 GHz boost clock deliver a complete, measured performance profile across Cinebench R15, R20, R23, and PassMark suites.

For users who prioritize theoretical specifications and are willing to wait for benchmark data, the AMD Ryzen Embedded 9900X offers a more compelling specification sheet. Twelve cores, 24 threads, a 5.60 GHz boost clock, 64 MB of L3 cache, and DDR5 memory support with 89.6 GB/s bandwidth position it as a potentially stronger processor for multi-threaded and memory-sensitive workloads. The 120 W TDP indicates this performance comes at a cost in power consumption, and the data does not yet show how that translates into actual benchmark scores.

The Intel part's 82nd percentile versus the AMD part's 50th percentile in the database is a striking gap, but it reflects data availability rather than necessarily raw capability. The AMD chip's 50th percentile with no benchmark entries is a placeholder ranking, not a measured result. The Intel chip's ranking is derived from its actual scores. The honest conclusion from the recorded data is that the Intel chip has proven performance, while the AMD chip has unproven but specification-strong potential. The 55 W TDP of the Intel part also makes it suitable for mobile platforms, as its BGA 1964 socket and mobile market segment indicate, while the AMD part targets desktop systems with its AM5 socket and 120 W TDP.
