AMD Ryzen Embedded 9950X3D vs Intel Core i5-14400 Comparison

Head-to-Head Benchmarks

The database contains a complete benchmark profile for the Intel Core i5-14400, while the AMD Ryzen Embedded 9950X3D currently has no recorded benchmark scores. This makes a direct score-to-score comparison impossible. The available data allows for an analysis of the Intel processor’s performance profile and its standing against its nearest rivals, but the AMD part’s actual workload performance remains unquantified in our measurements.

The Intel Core i5-14400 delivers a multi-core Cinebench R23 score of 21,315 and a single-core score of 3,009. In Cinebench R20, it scores 8,952 multi-core and 1,263 single-core. The older Cinebench R15 test shows 2,148 multi-core and 303 single-core. Geekbench results are 9,807 multi-core and 1,905 single-core. PassMark tests show a multi-thread score of 25,080 and a single-thread score of 3,741, with integer math at 82,017 and floating-point math at 61,549.

The nearest rivals for the Intel Core i5-14400, based on average benchmark score, are all within a narrow band. The Intel Core i7-12800H has an average score of 32,121, which is identical (0% delta). The Intel Core i7-13705H scores 32,076, placing it 0.1% behind the i5-14400. The Intel Core i5-14450HX scores 32,040, 0.2% behind. The Intel Core i9-11900 scores 32,226, which is 0.3% ahead. These deltas are negligible, indicating that the i5-14400 performs at parity with a range of mobile and desktop parts from previous generations in aggregate workload throughput.

The AMD Ryzen Embedded 9950X3D’s percentile rank is 50, which places it exactly at the median of all CPUs in the database. Its average benchmark score is recorded as zero, reflecting the absence of submitted benchmark runs. The Intel Core i5-14400, by contrast, holds an 82nd percentile rank, meaning it outperforms the majority of recorded CPUs. The Intel part’s average benchmark score is 32,115.

Architecture Differences

The architectural gap between these two processors is substantial. The AMD Ryzen Embedded 9950X3D is built on the Zen 5 (Granite Ridge) architecture, using a 4 nm process from TSMC. It integrates 16,630 million transistors across a dual-chiplet design with a die size of 2x 70.6 mm². The Intel Core i5-14400 uses the Raptor Lake Refresh architecture on Intel’s 10 nm process, with a monolithic die measuring 215 mm². The foundry and process node differences alone represent a generational manufacturing advantage for AMD.

Core and thread counts differ sharply. The AMD processor provides 16 cores and 32 threads, while the Intel processor provides 10 cores and 16 threads. Both have a base clock of 2.50 GHz for Intel versus 4.30 GHz for AMD, and boost clocks of 4.70 GHz for Intel versus 5.70 GHz for AMD. The AMD part has a 170 W TDP, while the Intel part has a 65 W TDP. This indicates that the AMD processor is designed for sustained high-performance workloads, whereas the Intel processor prioritizes lower power draw.

Cache hierarchies are also different. Both allocate 80 KB of L1 cache per core. The L2 cache is 1 MB per core on the AMD processor and 1.25 MB per core on the Intel processor. The L3 cache is a major differentiator: the AMD processor has 128 MB of L3 cache, while the Intel processor has 20 MB of shared L3. This sixfold difference in L3 capacity is a defining feature of the AMD part, likely benefiting workloads with large, reused data sets.

Memory support diverges as well. The AMD processor supports DDR5 memory only, with a dual-channel bus and a recorded memory bandwidth of 89.6 GB/s. The Intel processor supports both DDR4 and DDR5, also with a dual-channel bus, but its memory bandwidth is not recorded in the database. Both processors support ECC memory, which is notable for embedded and workstation use cases.

PCIe connectivity differs in lane count. The AMD processor provides Gen 5 with 24 lanes from the CPU, while the Intel processor provides Gen 5 with 16 lanes. Integrated graphics are present on both: the AMD part uses Radeon Graphics, while the Intel part uses UHD Graphics 730. The AMD processor has an unlocked multiplier, whereas the Intel processor is locked. The AMD part uses the AM5 socket, and the Intel part uses Socket 1700.

The AMD Ryzen Embedded 9950X3D was released on October 6, 2025, while the Intel Core i5-14400 was released on January 7, 2024. The Intel part has a launch MSRP of $221. No launch MSRP is recorded for the AMD part.

Where Each One Wins

The Intel Core i5-14400’s recorded benchmark data shows its strongest areas. The PassMark data compression score is 314,995, which is an exceptionally high output for a compression workload. The multi-thread PassMark score of 25,080 indicates strong parallel throughput for its core count. The Cinebench R23 multi-core score of 21,315 and Geekbench multi-core score of 9,807 both confirm that the Intel part handles multi-threaded productivity tasks well. Its single-thread performance, with a Geekbench score of 1,905 and a PassMark single-thread score of 3,741, is also solid.

The AMD Ryzen Embedded 9950X3D has no benchmark scores in the database, so its wins cannot be substantiated with measured numbers. However, the architectural data indicates where it would likely excel. The 16-core, 32-thread configuration with a 5.70 GHz boost clock and 128 MB of L3 cache is positioned for heavily threaded workloads that require large cache residency. The 170 W TDP and unlocked multiplier suggest that sustained all-core loads are a primary design target. The 89.6 GB/s memory bandwidth and 24 PCIe Gen 5 lanes further support data-intensive embedded applications.

The 82nd percentile rank for the Intel part, compared to the 50th percentile for the AMD part, reflects the fact that the Intel processor has an established benchmark history, while the AMD processor does not. The Intel part’s nearest rivals all score within 0.3% of it, indicating that it sits in a competitive performance tier. The AMD part’s percentile rank of 50 is a placeholder value, not a performance verdict.

The Verdict

The database presents a clear asymmetry. The Intel Core i5-14400 has a complete, verified benchmark record that places it at the 82nd percentile of all CPUs, with an average score of 32,115. Its nearest rivals, the Intel Core i7-12800H, Core i7-13705H, Core i5-14450HX, and Core i9-11900, all score within 0.3% of it. This indicates that the i5-14400 delivers performance that is fully competitive with a broad set of modern processors.

The AMD Ryzen Embedded 9950X3D has no benchmark scores. Its architectural specifications are markedly different: 16 cores, 32 threads, a 5.70 GHz boost clock, 128 MB of L3 cache, 170 W TDP, DDR5 support, and 24 PCIe Gen 5 lanes. These specifications describe a processor designed for a different performance envelope than the Intel part. The 65 W TDP and locked multiplier of the Intel part indicate a focus on efficiency and stability, while the AMD part’s 170 W TDP and unlocked multiplier indicate a focus on maximum throughput.

For workloads that are represented by the recorded benchmarks, the Intel Core i5-14400 is the only one of the two with measurable data. The choice between these two parts, based strictly on the database, depends on whether a user requires the unmeasured but architecturally substantial capabilities of the AMD part or the verified, established performance of the Intel part. The data shows that the Intel processor is a proven performer in its tier. The AMD processor’s specifications suggest high-end capability, but no benchmark evidence exists in the database to confirm it.
