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

AMD Ryzen Embedded 9900X3D is a 12-core, 24-thread processor built on the Zen 5 Granite Ridge architecture, using a 4 nm process from TSMC. It operates with a 4.40 GHz base clock and a 5.50 GHz boost clock, carries a 120 W TDP, and fits the AMD Socket AM5. Intel Core i5-14400T is a 10-core, 16-thread part from the Raptor Lake Refresh generation, built on a 10 nm process at Intel, with a 1.50 GHz base clock and a 4.50 GHz boost clock, a 35 W TDP, and the Intel Socket 1700. The database currently holds benchmark records for the Intel part only, so direct measured comparisons rely on that recorded data, while the AMD part is characterized by its listed specifications and architecture details.

Architecture Differences

The two processors come from different architectural lineages. The AMD Ryzen Embedded 9900X3D belongs to the 9000 series and uses the Granite Ridge codename, reflecting the Zen 5 generation. The Intel Core i5-14400T belongs to the Core 14th Gen series, uses the Raptor Lake codename, and is part of the Raptor Lake Refresh generation. The manufacturing processes differ as well: AMD uses a 4 nm process at TSMC, while Intel uses a 10 nm process at its own foundry.

The physical design shows a notable difference in die configuration. The AMD processor uses a chiplet layout described as 2x 70.6 mm², with a total transistor count of 16,630 million. The Intel processor uses a monolithic die of 215 mm², and the database lists no transistor count for it. The cache hierarchy also differs. Both parts have 80 KB of L1 cache per core, but the AMD part has 1 MB of L2 cache per core, while the Intel part has 1.25 MB of L2 cache per core. The largest difference is in L3 cache: the AMD part has 128 MB, while the Intel part has 20 MB shared.

Memory support separates the two further. The AMD Ryzen Embedded 9900X3D supports DDR5 memory only, with dual-channel operation and a listed memory bandwidth of 89.6 GB/s. The Intel Core i5-14400T supports both DDR4 and DDR5, also with dual-channel operation, but the database does not list a memory bandwidth figure for it. PCIe connectivity also differs: the AMD part provides Gen 5 with 24 lanes (CPU only), while the Intel part provides Gen 5 with 16 lanes (CPU only).

Integrated graphics are present on both. The AMD processor uses Radeon Graphics, while the Intel processor uses UHD Graphics 730. The AMD part has an unlocked multiplier, while the Intel part does not. The AMD processor is marked as part of the Ryzen Embedded product line, despite being listed in the desktop market segment, and it was released on 2025-10-06. The Intel processor was released on 2024-01-07, and its launch MSRP is $221.

Head-to-Head Benchmarks

The database contains benchmark records for the Intel Core i5-14400T across Cinebench and PassMark tests, but no recorded scores for the AMD Ryzen Embedded 9900X3D. The head-to-head comparison therefore uses the Intel part's measured results and the AMD part's listed specifications for context.

The Cinebench R15 multicore test records a score of 1732 for the Intel part, with a single-core score of 244. In Cinebench R20, the Intel part scores 7219 multicore and 1018 single-core. In Cinebench R23, the Intel part scores 17189 multicore and 2426 single-core. These results indicate that the Intel part's single-core performance scales consistently across the Cinebench versions, while the multicore scores show the expected increase with newer test versions.

PassMark results for the Intel part show a multithread score of 20223 and a single-thread score of 3512. The integer math test records 65667, floating point math records 49139, and extended instructions records 14562. Data compression scores 235636, while data encryption scores 13244. Random string sorting records 25181, physics records 1244, and finding prime numbers records 73.

The Intel part's average benchmark score is 27166, which places it at the 79th percentile among all CPUs in the database. Its nearest rivals in the database are close in average score: Intel Core i9-9900K has an average score of 27097, which is 0.3% lower; AMD Ryzen 7 5700G has an average score of 27051, which is 0.4% lower; Intel Core i7-13700H has an average score of 27355, which is 0.7% higher; and AMD Ryzen 3 PRO 5355G has an average score of 27382, which is 0.8% higher. These small percentage differences place the Intel part in a tight cluster with those four processors.

The AMD Ryzen Embedded 9900X3D has no recorded benchmark scores in the database, and its percentile versus all CPUs is listed at 50, with an average benchmark score of 0. The head-to-head benchmark array is empty for both parts, and the win counts are zero for both. The recorded data therefore cannot show direct measured wins for the AMD part, but its higher core count, higher boost clock, and larger L3 cache suggest a different performance envelope than the Intel part, which is constrained to a 35 W TDP and a 4.50 GHz boost.

Specification Differences

The two processors differ across nearly every major specification field. Core count: AMD has 12 cores, Intel has 10. Thread count: AMD has 24 threads, Intel has 16. Base clock: AMD runs at 4.40 GHz, Intel at 1.50 GHz. Boost clock: AMD reaches 5.50 GHz, Intel reaches 4.50 GHz. TDP: AMD is rated at 120 W, Intel at 35 W.

Socket types are not interchangeable: AMD uses AMD Socket AM5, Intel uses Intel Socket 1700. The process node differs, with AMD at 4 nm from TSMC and Intel at 10 nm from Intel. The die size differs, with AMD using 2x 70.6 mm² and Intel using 215 mm². Transistor count is listed for AMD at 16,630 million, while Intel has no listed count.

Cache configuration differs in L2 and L3. AMD has 1 MB of L2 per core, Intel has 1.25 MB per core. AMD has 128 MB of L3, Intel has 20 MB shared. Memory support: AMD supports DDR5 only, Intel supports DDR4 and DDR5. Memory bandwidth: AMD lists 89.6 GB/s, Intel lists none. PCIe: AMD provides Gen 5 with 24 lanes, Intel provides Gen 5 with 16 lanes.

Integrated graphics differ: AMD uses Radeon Graphics, Intel uses UHD Graphics 730. The multiplier is unlocked on AMD, locked on Intel. Release dates differ, with AMD on 2025-10-06 and Intel on 2024-01-07. Launch MSRP is listed only for Intel at $221, while AMD has no listed launch MSRP. Part numbers differ: AMD is 100-000001368E, Intel is SRN3N.

Where Each One Wins

The Intel Core i5-14400T has recorded benchmark results that place it at the 79th percentile among all CPUs, with an average score of 27166. Its nearest rivals are all within 0.8% of its average score, meaning the recorded data shows a tightly competitive field around this processor. The Intel part's strength in the database is its measured performance across Cinebench and PassMark tests, with a strong multithread score of 20223 and a single-thread score of 3512.

The AMD Ryzen Embedded 9900X3D does not have recorded benchmark scores, so its wins in the database are based on specification advantages rather than measured results. It holds a higher core count at 12 versus 10, a higher thread count at 24 versus 16, a higher boost clock at 5.50 GHz versus 4.50 GHz, and a substantially larger L3 cache at 128 MB versus 20 MB. Its 89.6 GB/s memory bandwidth is listed, while the Intel part has no listed bandwidth figure.

For workloads that depend on core count, thread count, and cache capacity, the AMD part's specifications indicate a potential advantage in heavily parallel tasks. For workloads that depend on measured single-thread and multithread scores, the Intel part has the recorded data showing its performance level. The Intel part also operates at a much lower TDP of 35 W compared to the AMD part's 120 W, which indicates a different thermal and power profile.

The Intel part supports both DDR4 and DDR5 memory, giving it broader memory compatibility, while the AMD part supports DDR5 only. The AMD part provides more PCIe lanes at 24 versus 16, both at Gen 5. The AMD part has an unlocked multiplier, which the Intel part lacks. Both support ECC memory, so that is not a differentiator.

The recorded data shows the Intel part's benchmark scores are competitive with its nearest rivals, all within 0.8% in average score. The AMD part's specification sheet shows a processor with higher core count, higher clocks, and a much larger cache, but without recorded benchmark data in the database, its performance position cannot be quantified relative to the Intel part. The win counts in the database are zero for both processors, reflecting the absence of head-to-head benchmark records.
