AMD Ryzen Embedded 9900X3D vs Intel Core i5-14400F Comparison

The Verdict

The Intel Core i5-14400F is the only one of these two processors with recorded benchmark data, and that data places it in the 83rd percentile of all CPUs in the database. The AMD Ryzen Embedded 9900X3D has no benchmark scores recorded, an average benchmark score of zero, and a percentile ranking of 50. For any workload where measured performance matters, the Intel part is the clear choice based on available evidence.

The Ryzen Embedded 9900X3D targets a different role. It is an unlocked 12-core, 24-thread processor on AMD Socket AM5 with 128 MB of L3 cache, designed for embedded systems. The Core i5-14400F is a locked 10-core, 16-thread desktop processor on Intel Socket 1700 with 20 MB of L3 cache. The data shows the Intel chip delivers strong multi-threaded results, scoring 21,645 in Cinebench R23 multi-core and 25,470 in PassMark multi-thread. The AMD part has no comparable scores, so the verdict for buyers is straightforward: if the database contains the only performance evidence, the i5-14400F is the proven performer, while the 9900X3D offers architectural features like a larger cache and PCIe Gen 5 with 24 lanes that the Intel chip does not match.

Users who need a desktop processor with verified multi-core throughput should choose the Intel Core i5-14400F. Users who require an embedded processor with 24 threads, a 128 MB L3 cache, ECC memory support, and PCIe Gen 5 with 24 lanes should consider the AMD part, but they must accept that no benchmark scores exist for it in the database.

Architecture Differences

The two processors come from different generations and manufacturing processes. The AMD Ryzen Embedded 9900X3D belongs to the 9000 series, uses the Granite Ridge codename, and is built on Zen 5 architecture. It is manufactured by TSMC on a 4 nm process node. The Intel Core i5-14400F belongs to the Core 14th Gen series, uses the Raptor Lake-R codename, and is built on Raptor Lake architecture. It is manufactured by Intel on a 10 nm process node. The process difference is substantial: AMD uses a 4 nm node, Intel uses a 10 nm node. The AMD chip integrates 16,630 million transistors across two 70.6 mm² dies, while the Intel chip has a single 215 mm² die with no transistor count recorded.

Core counts differ significantly. The AMD part has 12 cores and 24 threads, while the Intel part has 10 cores and 16 threads. The Intel chip uses a hybrid architecture common to Raptor Lake, with performance and efficiency cores, though the database does not specify the core mix. The AMD chip uses a unified Zen 5 core design. Cache configurations also diverge. Both have 80 KB of L1 cache per core. The AMD chip has 1 MB of L2 cache per core, while the Intel chip has 1.25 MB of L2 cache per core. The L3 cache is the largest difference: the AMD chip has 128 MB of L3 cache, while the Intel chip has 20 MB shared L3. The AMD part does not list a separate vCache3d figure, but the 128 MB L3 is already far larger than Intel's 20 MB.

Memory support differs as well. The AMD chip supports DDR5 only, with dual-channel memory and a recorded memory bandwidth of 89.6 GB/s. The Intel chip supports both DDR4 and DDR5, with dual-channel memory but no recorded memory bandwidth figure. Both support ECC memory. PCIe capabilities are different: the AMD chip provides PCIe Gen 5 with 24 lanes from the CPU, while the Intel chip provides PCIe Gen 5 with 16 lanes from the CPU. The AMD chip includes Radeon Graphics as integrated graphics, while the Intel chip has no integrated graphics at all, as indicated by the N/A entry.

Clock speeds also differ. The AMD chip has a base clock of 4.40 GHz and a boost clock of 5.50 GHz. The Intel chip has a base clock of 2.50 GHz and a boost clock of 4.70 GHz. The AMD chip has a TDP of 120 watts, while the Intel chip has a TDP of 65 watts. The AMD multiplier is unlocked, the Intel multiplier is locked. The AMD part was released on 2025-10-06, the Intel part on 2024-01-07. The Intel part has a recorded launch MSRP of $196, while the AMD part has no launch MSRP recorded. The Intel part number is SRN3RSRN47, the AMD part number is 100-000001368E.

Where Each One Wins

The Intel Core i5-14400F wins in every recorded benchmark category because it is the only processor with benchmark scores. The AMD Ryzen Embedded 9900X3D has zero recorded benchmark results in the database. The Intel chip shows strong multi-core capability with a Cinebench R23 multi-core score of 21,645, a Cinebench R20 multi-core score of 9,090, and a Cinebench R15 multi-core score of 2,181. Single-core performance is also recorded: Cinebench R23 single-core at 3,055, Cinebench R20 single-core at 1,283, and Cinebench R15 single-core at 307.

The Intel chip also delivers strong results in Geekbench, with a multi-core score of 11,268 and a single-core score of 2,058. PassMark results cover multiple workload types. The multi-thread score is 25,470, the single-thread score is 3,701. Data compression scores 315,521, data encryption scores 16,949, extended instructions scores 19,937, find prime numbers scores 86, floating point math scores 61,319, integer math scores 81,524, physics scores 1,523, and random string sorting scores 32,680.

The AMD chip does not have any of these numbers. Its average benchmark score is zero, and its percentile versus all CPUs is 50, which is the midpoint of the database distribution. The Intel chip has an average benchmark score of 32,279 and sits in the 83rd percentile. The data indicates that for any measured workload, the Intel chip outperforms the AMD chip in the database, not because of a head-to-head comparison, but because no scores exist for the AMD part.

The AMD chip does have architectural wins that are not benchmark-driven. It offers 24 threads versus Intel's 16 threads, which is a 50% thread advantage. It offers 128 MB of L3 cache versus Intel's 20 MB, which is more than six times the cache. It offers PCIe Gen 5 with 24 lanes versus Intel's 16 lanes. It has a higher boost clock of 5.50 GHz versus Intel's 4.70 GHz. These are specification wins, not performance wins, and they matter for embedded workloads that require large cache residency, high thread counts, or extensive PCIe connectivity.

Head-to-Head Benchmarks

There are no head-to-head benchmark entries in the database for these two processors. The wins counter shows zero for both sides. The AMD Ryzen Embedded 9900X3D has an empty benchmarks array, meaning no test scores were recorded for it. The Intel Core i5-14400F has a full set of scores, but without AMD scores, no direct comparison can be made.

The largest recorded wins belong to the Intel chip in absolute terms, but they are wins against the database's general population, not against the AMD part. The Intel chip's Cinebench R23 multi-core score of 21,645 is the highest single multi-core number in its recorded set. Its PassMark multi-thread score of 25,470 is the highest PassMark multi-thread figure. Its PassMark data compression score of 315,521 is the largest single score in the entire Intel data set. Its PassMark integer math score of 81,524 is also substantial. These numbers place the Intel chip in the 83rd percentile of all CPUs, with an average benchmark score of 32,279.

The nearest rivals in the database for the Intel chip are all close in average score. The AMD Ryzen 7 PRO 8840U has an average score of 32,233, which is 0.1% lower than the Intel chip. The Intel Core i9-11900 has an average score of 32,226, which is 0.2% lower. The AMD Ryzen 7 6800HS has an average score of 32,354, which is 0.2% higher. The Intel Core i7-12800H has an average score of 32,121, which is 0.5% lower. These delta percentages show the Intel chip sits in a tight cluster of comparable processors, all within 0.5% of each other.

The AMD Ryzen Embedded 9900X3D has no nearest rivals listed, no average score, and no percentile above the midpoint. Its percentile of 50 is exactly the median of the database distribution, which is consistent with a processor that has no measured data. The Intel chip's percentile of 83 is well above the median. The data indicates that the Intel chip outperforms the AMD chip in every recorded dimension, but this is a function of data availability, not a direct head-to-head measurement.
