AMD Ryzen Embedded 9900X3D vs Intel Core 7 251TE Comparison

Head-to-Head Benchmarks

The recorded data includes a full benchmark suite only for the Intel Core 7 251TE, while the AMD Ryzen Embedded 9900X3D has no benchmark entries in the database. This asymmetry limits direct head-to-head comparisons to measured results for the Intel part alone. The Intel Core 7 251TE achieves an average benchmark score of 41650, placing it at the 88th percentile among all CPUs in the database. Its nearest rivals include the Intel Core Ultra 7 265H at 41621 (0.1% behind), the Intel Core i7-14650HX at 41576 (0.2% behind), the Intel Core i7-12850HX at 41779 (0.3% ahead), and the Intel Core i7-14700T at 41914 (0.6% ahead). These delta values indicate the Intel Core 7 251TE sits in a tightly clustered performance band, with less than 1% separating it from its closest competitors.

Focusing on the Intel Core 7 251TE's measured scores, the Cinebench results show a multi-core strength. In Cinebench R15, the multicore score is 2572 against a single-core score of 362. The R20 run produces a multicore score of 10717 with a single-core score of 1512. In R23, the multicore score reaches 25518 while the single-core score is 3602. These figures indicate a substantial multi-threaded advantage over single-threaded performance, consistent with a 24-core, 32-thread configuration. The PassMark suite reinforces this pattern. The multithread score is 30022, while the single-thread score is 3568 (with a duplicate entry of 3568 for the singlethread test). Integer math scores 125739, floating-point math scores 85607, and extended instructions score 16974. Data compression reaches 334399, data encryption scores 22176, and random string sorting hits 39643. The find prime numbers score is 140, and the physics score is 1938.

For the AMD Ryzen Embedded 9900X3D, the database records zero benchmarks, a zero average benchmark score, and a 50th percentile ranking. This percentile is a placeholder rather than a measured result, as the absence of benchmark data means no performance comparisons can be drawn from the database. The head-to-head benchmark list is empty, and the wins counter shows zero for both processors. Therefore, any statement about relative performance between these two CPUs must rely on architectural and specification differences rather than measured scores. The Intel part's scores, however, show it is competitive with its nearest rivals, all within a 0.6% band, indicating that the recorded data places it in a solid mid-to-high performance tier based on the 88th percentile ranking.

Architecture Differences

The AMD Ryzen Embedded 9900X3D uses the Granite Ridge codename from the Ryzen Embedded generation, built on Zen 5 architecture. It is fabricated on a 4 nm process at TSMC, with a transistor count of 16,630 million and a die size of 2x 70.6 mm². The Intel Core 7 251TE uses the Bartlett Lake codename from the Core 7 generation, built on a 10 nm process at Intel, with a die size of 215 mm² and no transistor count recorded. The process node difference is significant: the AMD part uses a smaller 4 nm node versus Intel's 10 nm node, which typically indicates higher transistor density and potentially better power efficiency per unit area, though the AMD part has a higher TDP.

Core and thread counts differ markedly. The AMD Ryzen Embedded 9900X3D has 12 cores and 24 threads, while the Intel Core 7 251TE has 24 cores and 32 threads. The Intel part offers double the core count and eight additional threads. Clock speeds show the AMD part with a base clock of 4.40 GHz and a boost clock of 5.50 GHz, versus the Intel part's base clock of 1.40 GHz and boost clock of 5.40 GHz. The AMD part has a much higher base clock, while boost clocks are nearly identical.

Cache configurations reveal distinct designs. Both processors share an L1 cache of 80 KB per core. The L2 cache differs: the AMD part has 1 MB per core, while the Intel part has 1.25 MB per core. The L3 cache shows a major divergence. The AMD Ryzen Embedded 9900X3D has 128 MB of L3 cache, which is characteristic of the 3D V-Cache line, though the vCache3d field is null in the database. The Intel Core 7 251TE has 36 MB of shared L3 cache. The AMD part's L3 cache is over three times larger, which can benefit workloads with large working sets.

Socket and platform support differ. The AMD part uses AMD Socket AM5, while the Intel part uses Intel Socket 1700. Memory support also differs: the AMD part supports DDR5 only, while the Intel part supports both DDR4 and DDR5. Both use dual-channel memory buses with identical memory bandwidth of 89.6 GB/s. Both support ECC memory. PCIe lanes differ: the AMD part has Gen 5 with 24 lanes (CPU only), while the Intel part has Gen 5 with 16 lanes (CPU only). Integrated graphics differ as well: the AMD part uses Radeon Graphics, while the Intel part uses UHD Graphics 770.

The AMD part has an unlocked multiplier, while the Intel part is locked. The AMD part was released on 2025-10-06, and the Intel part on 2025-01-12. The Intel part has a launch MSRP of $384, while the AMD part has no launch MSRP recorded. Production status is active for both.

The Verdict

The data presents two processors with fundamentally different design priorities. The AMD Ryzen Embedded 9900X3D emphasizes high clock speeds with a 4.40 GHz base and 5.50 GHz boost, combined with a large 128 MB L3 cache. Its 12 cores and 24 threads are arranged around Zen 5 architecture on a 4 nm TSMC process. The Intel Core 7 251TE counters with 24 cores and 32 threads, a 5.40 GHz boost clock, and a lower 1.40 GHz base clock. It uses a 10 nm Intel process with a 36 MB shared L3 cache and supports both DDR4 and DDR5 memory.

The database contains benchmark scores for the Intel Core 7 251TE, with an average score of 41650 and an 88th percentile ranking. Its nearest rival deltas are all within 0.6%, showing it performs consistently with similar Intel parts. The AMD Ryzen Embedded 9900X3D has no recorded benchmarks, so its performance cannot be compared directly from the data. The Intel part's measured results indicate strong multi-threaded performance: the Cinebench R23 multicore score of 25518 versus a single-core score of 3602 shows a 7.1:1 ratio, while the PassMark multithread score of 30022 versus a single-thread score of 3568 shows a similar emphasis.

From a specification standpoint, the Intel Core 7 251TE offers more cores and threads, a lower TDP of 45 versus 120, and support for DDR4 in addition to DDR5. The AMD Ryzen Embedded 9900X3D offers a higher base clock, a larger L3 cache, more PCIe lanes (24 versus 16), and an unlocked multiplier. The AMD part also has a smaller process node and a higher transistor count. The Intel part has a recorded launch MSRP of $384, while the AMD part has no price data in the database.

For users prioritizing multi-threaded workloads and lower power consumption, the recorded data favors the Intel Core 7 251TE, given its 24 cores, 32 threads, and 45 TDP, alongside measured benchmark scores that place it at the 88th percentile. For users prioritizing high base clocks, a massive L3 cache, and an unlocked multiplier, the AMD Ryzen Embedded 9900X3D is the choice based on its specifications, though no benchmark data exists to confirm its performance. The absence of AMD benchmark scores means any selection between these two must weigh the Intel part's measured results against the AMD part's unverified specifications. The Intel part's nearest rivals, all within 0.6% in average score, reinforce that it competes in a tight performance band, while the AMD part's 50th percentile placeholder suggests it has no recorded standing in the database.
