AMD Ryzen 5 7400F vs Intel Core 7 251E Comparison

The AMD Ryzen 5 7400F and Intel Core 7 251E are both 65 W desktop processors, but they target completely different corners of the market. The Ryzen 5 7400F is a 6-core, 12-thread chip built on a modern 5 nm process, while the Core 7 251E is a 24-core, 32-thread part using Intel's older 10 nm node. The database contains a full set of benchmark results for the AMD part, while the Intel part has no recorded benchmark scores, so the analysis relies on architectural data and the AMD unit's measured performance relative to its nearest rivals.

Where Each One Wins

The AMD Ryzen 5 7400F wins in any workload that depends on high per-core clock speeds and efficient instruction execution. Its recorded boost clock is 4.70 GHz, and its single-thread benchmark results are strong: 309 points in Cinebench R15 single-core, 1290 in R20, and 3072 in R23. These scores place it in the 83rd percentile of all CPUs in the database, meaning it outperforms the majority of processors in single-thread tasks such as older games, lightly threaded applications, and everyday desktop use.

The Intel Core 7 251E wins on raw core count and multi-threaded capacity, at least on paper. It has 24 cores and 32 threads, which is four times the core count of the AMD chip. Its boost clock is higher at 5.60 GHz, but its base clock is much lower at 2.10 GHz versus 3.70 GHz for the AMD part. The Intel chip also carries 36 MB of shared L3 cache, 4 MB more than the AMD's 32 MB. The Intel part includes UHD Graphics 770 integrated graphics, which gives it a functional advantage for systems that do not use a discrete GPU. The AMD chip has no integrated graphics at all.

Architecture Differences

The two processors come from different foundries and use different process nodes. The AMD Ryzen 5 7400F is built on TSMC's 5 nm process, with 6,570 million transistors on a 71 mm² die. Its architecture is Zen 4, codenamed Raphael, and it uses AMD Socket AM5. The Intel Core 7 251E uses Intel's 10 nm process, with a much larger die size of 257 mm². Its codename is Bartlett Lake, and it fits in Intel Socket 1700.

Cache layouts differ significantly. The AMD chip has 64 KB of L1 cache per core, 1 MB of L2 per core, and 32 MB of shared L3. The Intel chip has 80 KB of L1 per core, 2 MB of L2 per core, and 36 MB of shared L3. The Intel part's larger per-core caches and higher total L3 could help in workloads that repeatedly access a working set that exceeds the AMD's cache capacity.

Memory support also differs. The AMD part supports DDR5 only, with dual-channel memory and a recorded bandwidth of 83.2 GB/s. The Intel part supports both DDR4 and DDR5, also dual-channel, with a higher recorded bandwidth of 89.6 GB/s. Both support ECC memory. PCIe connectivity differs: the AMD chip provides Gen 5 with 24 CPU lanes, while the Intel chip provides Gen 5 with 16 CPU lanes. The Intel part has a locked multiplier, while the AMD part is unlocked for overclocking.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark results between the Ryzen 5 7400F and the Core 7 251E. The Intel part's benchmark array is empty, and its average benchmark score is recorded as 0. The AMD part has a full set of measurements, including Cinebench R15, R20, and R23 scores, as well as PassMark tests.

What the data does show is where the AMD chip stands among its nearest rivals. The Ryzen 5 7400F's average benchmark score is 32,750. Its closest competitor in the database is the Intel Core i5-14600T, which averages 32,707, a delta of 0.1 percent. The AMD chip leads that rival by a hair. It also leads the Intel Core Ultra 7 155H (32,697, delta 0.2) and the AMD Ryzen AI 7 PRO 360 (32,662, delta 0.3). The only rival that beats it is the AMD Ryzen 7 PRO 6850H, which scores 32,812, a delta of -0.2 percent, meaning the Ryzen 5 7400F trails that part by two-tenths of a percent.

For the Intel Core 7 251E, there is no comparable data. Its percentile ranking is 50, which is the median of the database, but that figure comes with an average score of 0, so it likely reflects an incomplete record rather than a measured performance level. The practical reading is that the Intel chip's 24-core configuration provides a theoretical multi-threading advantage, but its performance cannot be quantified from the recorded data.

The Verdict

The data clearly favors the AMD Ryzen 5 7400F for users who need verified, measurable performance. Its benchmark suite is complete, and its scores place it in the 83rd percentile of all CPUs. It delivers strong single-core results, which matter for responsiveness and for applications that do not scale across many threads. Its 6 cores and 12 threads are sufficient for mainstream desktop workloads, and its 5 nm process suggests efficient operation within its 65 W TDP.

The Intel Core 7 251E is a different proposition. With 24 cores, 32 threads, and a 5.60 GHz boost clock, it is designed for heavily parallel workloads where core count dominates. Its support for both DDR4 and DDR5 gives system builders flexibility, and its integrated UHD Graphics 770 removes the need for a discrete GPU in basic systems. However, the lack of any recorded benchmark scores means the database cannot confirm its actual performance. Its 10 nm process and larger die size indicate it is a more power-hungry design at the same 65 W TDP, likely with lower sustained clocks under full load.

For a builder who wants a processor with proven results, the Ryzen 5 7400F is the only one in this comparison with measured data. For a builder who needs maximum core count and does not require integrated graphics, the Intel part offers more raw threads on paper, but its real-world standing remains unverified.
