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

Head-to-Head Benchmarks

The Intel Core i5-14400 is the only processor in this comparison with recorded benchmark data. The AMD Ryzen Embedded 9900X3D has no benchmark scores in the database, so direct head-to-head results cannot be established. All wins belong to the Intel part by default, as it is the sole chip with measurable performance metrics.

The Core i5-14400 posts a Cinebench R23 multi-core score of 21,315 and a single-core score of 3,009. In Geekbench, it records 9,807 multi-core and 1,905 single-core. PassMark results show 25,080 in multithread, 3,741 in single-thread, 82,017 in integer math, and 61,549 in floating point math. Data compression scores 314,995, encryption scores 16,731, extended instructions score 19,816, prime number finding scores 80, random string sorting scores 32,346, and physics scores 1,396.

The database places the Core i5-14400 at the 82nd percentile among all CPUs, with an average benchmark score of 32,115. Its nearest rivals include the Intel Core i7-12800H at 32,121 (0% delta), the Intel Core i7-13705H at 32,076 (0.1% delta), the Intel Core i5-14450HX at 32,040 (0.2% delta), and the Intel Core i9-11900 at 32,226 (-0.3% delta). These deltas indicate the Core i5-14400 sits within a tight cluster of comparable mobile and desktop processors, trailing the i7-12800H by a negligible margin and leading the i9-11900 by 0.3%.

Since the Ryzen Embedded 9900X3D lacks any recorded scores, the data cannot demonstrate its performance relative to the Core i5-14400. The AMD part's percentile ranking of 50 with an average benchmark score of 0 suggests no measurements exist in the database for this processor.

The Intel Core i5-14400 is part of the Core 14th Gen series with the Raptor Lake-R codename, built on the Raptor Lake architecture at Intel's 10 nm process node. It has 10 cores and 16 threads. The die size is 215 mm². Cache includes 80 KB of L1 per core, 1.25 MB of L2 per core, and 20 MB of shared L3 cache. Memory support spans DDR4 and DDR5 in dual-channel configuration. ECC memory is supported. PCIe connectivity provides Gen 5 with 16 lanes from the CPU. Integrated graphics use UHD Graphics 730. The multiplier is locked, and the part number is SRN3QSRN46.

The AMD chip uses a smaller 4 nm process compared to Intel's 10 nm node, which suggests denser transistors and potentially better power characteristics. The AMD part also brings twice the PCIe lanes (24 versus 16) and a significantly larger L3 cache (128 MB versus 20 MB). The Intel part offers broader memory compatibility with both DDR4 and DDR5, while the AMD chip is limited to DDR5. Both processors support ECC memory, a notable feature for embedded and workstation use.

The Ryzen Embedded 9900X3D carries a base clock of 4.40 GHz and a boost clock of 5.50 GHz, with a 120 W TDP. The Core i5-14400 has a base clock of 2.50 GHz and a boost clock of 4.70 GHz, with a 65 W TDP. The AMD part operates at higher frequencies across the board but consumes nearly twice the power budget. The Intel chip's lower TDP reflects a more conservative power envelope.

The Verdict

The data presents a clear split. The Intel Core i5-14400 is a measured, benchmarked processor with a substantial record of performance scores. It holds an 82nd percentile ranking among all CPUs and an average benchmark score of 32,115. Its nearest rivals cluster within a 0.3% delta band, indicating consistent, predictable performance in its class. The Cinebench R23 multi-core score of 21,315 and single-core score of 3,009 establish a solid baseline for both threaded and lightly threaded workloads. PassMark results reinforce this with strong integer math (82,017) and floating point math (61,549) scores.

The AMD Ryzen Embedded 9900X3D offers no benchmark data in the database. Its average score is recorded as 0, and its percentile ranking of 50 appears to be a default value rather than a measured outcome. Without recorded scores, no performance claims can be made from the measurement data. The hardware specification sheet, however, shows a part with 12 cores, 24 threads, a 5.50 GHz boost clock, 128 MB of L3 cache, and 24 PCIe Gen 5 lanes. These specifications suggest higher theoretical throughput and greater I/O capacity than the Intel part, but the database provides no empirical confirmation.

The choice between these two processors depends on what the data can support. The Intel Core i5-14400 is the only option with verified benchmark results. It delivers documented multi-core and single-core performance, a strong average score, and close competitive positioning against similar processors. The AMD Ryzen Embedded 9900X3D remains an unmeasured quantity in this database. Its specifications point to a higher-core-count, higher-clock, higher-cache design with more PCIe lanes, but the absence of benchmark scores leaves its actual performance unverified.

For users who require confirmed performance data, the Intel Core i5-14400 is the only processor in this comparison with measurements to back its claims. For users who prioritize the raw specifications of more cores, more threads, higher clocks, larger cache, and more PCIe lanes, the AMD Ryzen Embedded 9900X3D presents a compelling specification sheet, though its performance remains undocumented in the database. The Intel part also carries a recorded launch MSRP of $221, while the AMD part's launch price is not recorded.
