AMD Ryzen 5 7400 vs Intel Core 7 251E Comparison

The Verdict

The data presents a clear split. The AMD Ryzen 5 7400 is a finished product with a full set of recorded benchmark results, placing it in the 88th percentile of all tested CPUs. It is a proven performer for desktop workloads. The Intel Core 7 251E, with no recorded benchmarks in the database and a 50th percentile placement, is a specification sheet without performance evidence. For any builder who wants verified numbers, the Ryzen 5 7400 is the only option with actual data to support a purchasing decision. The Intel part offers more cores and threads on paper, but its lack of benchmark data means its real-world behavior is unquantified. The Ryzen 5 7400 is the logical pick for anyone who needs a processor with known, measured performance. The Core 7 251E is a choice based on specifications and potential, not on demonstrated results.

Architecture Differences

The two processors come from different design philosophies. The AMD Ryzen 5 7400 uses the Zen 4 architecture, codenamed Raphael, built on a 5 nm process at TSMC. It features 6 cores and 12 threads. The Intel Core 7 251E, codenamed Bartlett Lake, is built on a 10 nm process at Intel and uses a larger, more complex layout with 24 cores and 32 threads. The transistor counts differ sharply: AMD reports 6,570 million transistors on a 71 mm² die, while Intel lists no transistor count but shows a 257 mm² die size.

Memory support is another dividing line. The Ryzen 5 7400 supports only DDR5 in a dual-channel configuration with 83.2 GB/s of bandwidth. The Core 7 251E supports both DDR4 and DDR5, also dual-channel, with a slightly higher memory bandwidth of 89.6 GB/s. Both support ECC memory. PCIe connectivity differs as well: the AMD part provides Gen 5 with 24 lanes from the CPU, while the Intel part provides Gen 5 with 16 lanes.

Cache structures are distinct. The Ryzen 5 7400 uses 64 KB of L1 per core, 1 MB of L2 per core, and a shared 16 MB L3. The Core 7 251E has 80 KB of L1 per core, 2 MB of L2 per core, and a shared 36 MB L3. The Intel part has a larger L3 cache, which could help in some multi-threaded workloads, but again, this is unverified by any benchmark data. The integrated graphics also differ: AMD includes Radeon Graphics, while Intel includes UHD Graphics 770.

The socket and platform are incompatible. AMD uses Socket AM5, while Intel uses Socket 1700. The AMD part has an unlocked multiplier for overclocking; the Intel part is locked. The Ryzen 5 7400 was released later, with a release date of 2025-09-15, while the Core 7 251E was released earlier, on 2025-01-12.

Where Each One Wins

Based on the recorded data, the Ryzen 5 7400 wins in every measurable category. Its benchmark suite covers a wide range of tests, and the results are strong. The PassMark single-thread score of 3248 is a solid figure for desktop use. The multi-thread score of 21712 indicates capable parallel performance. The data compression score of 261749 and integer math score of 64733 show strong general computing throughput. The floating point math score of 40784 and extended instructions score of 19924 further confirm its capability in compute-heavy tasks.

The Intel Core 7 251E has no recorded wins because it has no recorded benchmark scores. On paper, its 24 cores and 32 threads suggest it could outperform the Ryzen 5 7400 in heavily threaded scenarios, and its higher boost clock of 5.60 GHz versus 4.30 GHz could give it an edge in single-threaded work. But none of that is verified. The database shows no wins for either processor in a head-to-head comparison, as the head-to-head benchmark list is empty. In practice, the Ryzen 5 7400 is the only one with a track record, so it is the default winner in any workload category until the Intel part produces measurable results.

The Ryzen 5 7400 also carries a higher percentile ranking: 88th versus 50th for the Intel part. That percentile reflects all CPUs in the database, and it is based on actual testing. The Intel part sits at the median, which for a processor with no benchmarks likely indicates a placeholder position rather than a measured performance level.

FAQ

Q: Which processor has a higher single-thread score?

A: The AMD Ryzen 5 7400 has a recorded PassMark single-thread score of 3248. The Intel Core 7 251E has no recorded benchmark scores, so no comparison is possible from the data.

Q: Does the Intel Core 7 251E support DDR4 memory?

A: Yes, the Intel Core 7 251E supports both DDR4 and DDR5 memory. The AMD Ryzen 5 7400 supports only DDR5.

Q: What is the process node for each processor?

A: The AMD Ryzen 5 7400 is built on a 5 nm process at TSMC. The Intel Core 7 251E is built on a 10 nm process at Intel.

Q: Are both processors unlocked for overclocking?

A: No. The AMD Ryzen 5 7400 has an unlocked multiplier. The Intel Core 7 251E is locked.

Q: Which processor has more cores and threads?

A: The Intel Core 7 251E has 24 cores and 32 threads. The AMD Ryzen 5 7400 has 6 cores and 12 threads.

Q: Does the database show any benchmark results for the Intel Core 7 251E?

A: No. The Intel Core 7 251E has an empty benchmark list and an average benchmark score of 0. The AMD Ryzen 5 7400 has a full set of recorded scores.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark entries between the AMD Ryzen 5 7400 and the Intel Core 7 251E. The head-to-head list is empty, and the win counts for both processors are zero. This means a direct comparison of measured performance is impossible.

What can be compared is the Ryzen 5 7400's recorded scores against the broader database. Its average benchmark score is 42055. Its nearest rivals show how close the competition is: the AMD Ryzen 9 PRO 8945HS scores 41963, which is 0.2% behind. The Intel Core i7-14700T scores 41914, 0.3% behind. The Intel Core i7-12850HX scores 41779, 0.7% behind. The Intel Core i9-12900K scores 42335, which is 0.7% ahead of the Ryzen 5 7400. These deltas are tiny, indicating that the Ryzen 5 7400 sits in a very tight performance band around the 42000 mark.

The Ryzen 5 7400's individual scores reinforce that position. The multi-thread score of 21712 and the single-thread score of 3248 are both respectable. The data encryption score of 14865 and the find prime numbers score of 79 are part of a balanced profile. The random string sorting score of 31110 and the physics score of 1150 round out the suite. These numbers are all recorded and verifiable.

For the Intel Core 7 251E, there is nothing to walk through. Its average benchmark score is 0, and its percentile is 50. The specifications suggest potential: a 5.60 GHz boost clock, 36 MB of shared L3, and 32 threads. But the data stops there. Any claim about its performance would be speculation. The database records no wins, no scores, and no rivals for this part. The Ryzen 5 7400, by contrast, has a complete profile with measurable results.
