AMD Ryzen 5 5500X3D vs Intel Core 7 251E Comparison

Head-to-Head Benchmarks

The benchmark database contains a complete PassMark suite for the AMD Ryzen 5 5500X3D, while the Intel Core 7 251E currently has no recorded benchmark scores. This asymmetry shapes the entire comparison. The Ryzen 5 5500X3D posts an average benchmark score of 37,018, placing it in the 85th percentile among all CPUs tracked. The Intel Core 7 251E, with an average score of zero and a 50th percentile ranking, cannot be directly compared on raw performance until its own measurements are entered into the database.

Looking at the Ryzen 5 5500X3D's individual PassMark results, the strongest showing comes in data compression with a score of 230,392. Integer math follows at 60,033, while random string sorting reaches 23,675. Floating point math scores 34,511, and extended instructions hit 15,925. Data encryption records 13,967, and the find prime numbers test produces 170. The multi-thread score of 20,363 and single-thread score of 2,941 round out the suite, with physics scoring 2,282.

The Ryzen 5 5500X3D's nearest rivals in the database provide context for its standing. The AMD Ryzen 5 5600F averages 36,945, putting the 5500X3D 0.2% ahead. The Intel Core Ultra 5 225 also averages 36,938, again 0.2% behind the 5500X3D. The AMD Ryzen AI 7 PRO 450 averages 37,093, meaning the 5500X3D trails by 0.2%. The Intel Core i9-12900T averages 37,112, putting the 5500X3D 0.3% behind. These deltas are narrow, indicating the 5500X3D sits in a tightly clustered performance band among its direct competitors.

The Intel Core 7 251E has no head-to-head benchmark entries in the database, and no wins are recorded for either processor in direct comparisons. The lack of scores for the Intel part means the database cannot yet confirm how its 24 cores and 32 threads translate into measurable performance. What can be stated from the recorded data is that the Ryzen 5 5500X3D holds a documented performance profile, while the Core 7 251E remains unmeasured.

The Verdict

From the available data, the AMD Ryzen 5 5500X3D is the only processor in this pairing with a verified performance record. Its 85th percentile ranking among all CPUs, combined with an average score of 37,018, shows it sits comfortably above the median processor. The nearest rival comparisons confirm this position: it trades blows within 0.3% of the Ryzen 5 5600F, Ryzen AI 7 PRO 450, Core Ultra 5 225, and Core i9-12900T. For workloads represented by the PassMark suite, the 5500X3D delivers consistent mid-to-high tier results.

The Intel Core 7 251E cannot be recommended on measured performance because the database contains no benchmark scores for it. Its 50th percentile ranking and zero average score indicate that it has not been subjected to the same testing, or the results have not been recorded. Users who require benchmark-verified performance should look to the 5500X3D, which has a full suite of recorded measurements. Those who need the Core 7 251E's specific feature set, such as its integrated graphics or higher boost clock, would have to wait for its benchmark data to appear before making a data-driven choice.

The choice between these two processors, based strictly on the database, favors the AMD part. It has measurable results across eleven distinct tests, a clear percentile standing, and comparable scores to four named rivals. The Intel part offers no recorded performance data, leaving its actual capability unknown. Until the database receives scores for the Core 7 251E, the Ryzen 5 5500X3D stands as the only processor here with verified performance credentials.

Architecture Differences

The AMD Ryzen 5 5500X3D uses the Zen 3 architecture under the Vermeer codename, built on a 7 nm process at TSMC. The die size measures 74 mm². It features 6 cores and 12 threads, with a base clock of 3.00 GHz and a boost clock of 4.00 GHz. The cache hierarchy includes 64 KB of L1 per core, 512 KB of L2 per core, and 96 MB of shared L3 cache. This large L3 allocation is a defining characteristic of the processor, providing a substantial cache pool for data reuse across cores.

The Intel Core 7 251E uses the Bartlett Lake codename, built on a 10 nm process at Intel. The die size spans 257 mm², significantly larger than the AMD part. It features 24 cores and 32 threads, with a base clock of 2.10 GHz and a boost clock of 5.60 GHz. The cache configuration includes 80 KB of L1 per core, 2 MB of L2 per core, and 36 MB of shared L3 cache. The higher per-core L2 allocation and the larger L3 in the AMD part represent different cache strategies: the Intel design emphasizes per-core resources, while the AMD design pools a large shared L3.

Both processors support ECC memory, and both are locked multipliers. The AMD part uses AMD Socket AM4, while the Intel part uses Intel Socket 1700. The process node difference, 7 nm versus 10 nm, places the AMD part on a denser manufacturing process, which often correlates with lower power draw per transistor, though the TDP figures differ significantly: the 5500X3D has a 105 W TDP, while the 251E has a 65 W TDP.

The memory support differs as well. The Ryzen 5 5500X3D supports DDR4 only, with dual-channel memory bus and a bandwidth of 51.2 GB/s. The Core 7 251E supports both DDR4 and DDR5, also dual-channel, with a higher bandwidth of 89.6 GB/s. This gives the Intel part a memory bandwidth advantage on paper, assuming DDR5 modules are used.

PCIe capabilities also diverge. The AMD processor provides Gen 4 with 20 lanes (CPU only), while the Intel processor provides Gen 5 with 16 lanes (CPU only). The Gen 5 interface offers higher per-lane bandwidth, though the AMD part has more total lanes. Integrated graphics are absent on the 5500X3D, while the 251E includes UHD Graphics 770.

Specification Differences

The two processors differ across several specification fields. Core count: the Ryzen 5 5500X3D has 6 cores versus the Core 7 251E's 24 cores. Thread count: 12 versus 32. Base clock: 3.00 GHz versus 2.10 GHz. Boost clock: 4.00 GHz versus 5.60 GHz. TDP: 105 W versus 65 W. Socket: AM4 versus Socket 1700. Process node: 7 nm versus 10 nm. Foundry: TSMC versus Intel. Die size: 74 mm² versus 257 mm².

Cache sizes differ across all levels. L1 per core: 64 KB versus 80 KB. L2 per core: 512 KB versus 2 MB. L3 shared: 96 MB versus 36 MB. Memory support: DDR4 only versus DDR4 and DDR5. Memory bandwidth: 51.2 GB/s versus 89.6 GB/s. PCIe generation: Gen 4 versus Gen 5. PCIe lanes: 20 versus 16. Integrated graphics: none versus UHD Graphics 770.

Release dates also differ. The Ryzen 5 5500X3D was released on June 4, 2025. The Core 7 251E was released on January 12, 2025. The Intel part has a launch MSRP of $384, while the AMD part has no recorded launch MSRP. Part numbers differ as well: 100-000001504 for the AMD, SRQDUQ657 for the Intel. Both are active in production, both are locked multipliers, and both support ECC memory.

The generation field shows the AMD part as "Ryzen 5 (Zen 3 (Vermeer))" and the Intel part as "Core 7 (Bartlett Lake)". The series field for the Intel part is null, while the AMD part lists "5000 series". The average benchmark score differs dramatically: 37,018 for the AMD, 0 for the Intel. Percentile rankings: 85 for the AMD, 50 for the Intel. The nearest rivals list is populated for the AMD part but empty for the Intel part.
