AMD Ryzen 5 3501U vs Intel Core 7 251E Comparison

Head-to-Head Benchmarks

The recorded benchmark data for this comparison is one-sided. The AMD Ryzen 5 3501U has a complete set of PassMark measurements, while the Intel Core 7 251E has no benchmark scores recorded in the database at all. The database shows zero head-to-head benchmark entries, zero wins for either processor, and an average benchmark score of 0 for the Intel part. This means the analysis must rely on the AMD processor's absolute scores and the architectural specifications of both chips, rather than direct comparative measurements.

The AMD Ryzen 5 3501U delivers a single-thread score of 2136 and a multithread score of 7071 in the PassMark suite. Its avgBenchmarkScore sits at 14320, placing it in the 69th percentile among all CPUs tracked in the database. The nearest rivals in the database include the AMD Ryzen Embedded V2546 with an average score of 14336 and a delta of -0.1%, the AMD Ryzen 3 7320C at 14277 with a delta of 0.3%, the Intel Core 7 160UL at 14232 with a delta of 0.6%, and the Intel Core i5-10400F at 14185 with a delta of 1%. These deltas are all within a single percentage point, indicating that the Ryzen 5 3501U sits in a tightly clustered performance band where no rival separates itself by more than 1%.

In the individual PassMark workloads, the Ryzen 5 3501U shows its strongest absolute performance in data compression with a score of 87380. Integer math scores 26321, floating point math scores 12707, random string sorting scores 10414, and data encryption scores 5580. Extended instructions deliver 3274, while physics scores 483 and finding prime numbers scores 21. The multithread score of 7071 versus the single-thread score of 2136 indicates a scaling factor of roughly 3.3x across the four physical cores, which is consistent with a quad-core, four-thread design without simultaneous multithreading.

Architecture Differences

The two processors come from different architectural lineages. The AMD Ryzen 5 3501U belongs to the 3000 series and uses the Picasso codename, built on the Zen+ (Picasso) generation. It is fabricated by GlobalFoundries on a 12 nm process with 4,940 million transistors and a die size of 210 mm². The Intel Core 7 251E belongs to the Bartlett Lake codename and generation, fabricated by Intel on a 10 nm process with a die size of 257 mm². The transistor count for the Intel part is not recorded in the database.

Cache layout differs substantially. The AMD processor has 96 KB of L1 cache per core, 512 KB of L2 cache per core, and 4 MB of shared L3 cache. The Intel processor has 80 KB of L1 cache per core, 2 MB of L2 cache per core, and 36 MB of shared L3 cache. The Intel L3 cache is 9 times larger in total capacity, which reflects the much higher core count.

Memory support also diverges. The AMD Ryzen 5 3501U supports DDR4 memory over a dual-channel bus with a memory bandwidth of 38.4 GB/s. The Intel Core 7 251E supports both DDR4 and DDR5 memory over a dual-channel bus with a memory bandwidth of 89.6 GB/s, more than double the AMD figure. ECC memory is supported on the Intel part only. PCIe connectivity differs as well: the AMD chip uses Gen 3, while the Intel chip uses Gen 5 with 16 lanes (CPU only).

The power envelopes are far apart. The AMD Ryzen 5 3501U has a TDP of 15 watts and is classified as a mobile part on AMD Socket FP5. The Intel Core 7 251E has a TDP of 65 watts and is classified as a desktop part on Intel Socket 1700. This places the two chips in different market segments entirely, one aimed at low-power mobile systems and the other at desktop systems with more thermal headroom.

The Intel part carries a launch MSRP of $384. The AMD part has no recorded launch MSRP in the database.

The Verdict

The data does not permit a direct performance verdict because the Intel Core 7 251E has no recorded benchmark scores. What the data does show is a clear separation in design intent and measured capability for the AMD side. The Ryzen 5 3501U delivers a complete set of PassMark scores and an average benchmark score of 14320, placing it in the 69th percentile of all CPUs. Its nearest rivals are all within 1% of its average score, confirming that it performs in line with other mid-range processors in the database.

The Intel Core 7 251E, by contrast, presents only specifications. It offers 24 cores and 32 threads versus 4 cores and 4 threads for the AMD part, a 5.60 GHz boost clock versus 3.70 GHz, 36 MB of shared L3 cache versus 4 MB, DDR5 support with 89.6 GB/s bandwidth versus 38.4 GB/s on DDR4, PCIe Gen 5 versus Gen 3, and ECC memory support. These are substantial architectural advantages on paper. The TDP difference of 65 watts versus 15 watts indicates the Intel part requires far more power delivery and cooling, which is consistent with its desktop classification.

The verdict from the recorded data is conditional. For anyone relying on measured benchmark results, only the AMD Ryzen 5 3501U has verified scores. For anyone evaluating on specifications alone, the Intel Core 7 251E holds the advantage in core count, cache, memory bandwidth, PCIe generation, and boost clock. The absence of Intel benchmark data in the database means no quantitative confirmation of that advantage exists yet.

Where Each One Wins

The AMD Ryzen 5 3501U wins in the only category with measured data: verified benchmark performance. Its PassMark scores across data compression, encryption, extended instructions, prime number finding, floating point math, integer math, multithread, physics, random string sorting, and single-thread tests are all recorded and place it in the 69th percentile of all CPUs. The tight clustering of its nearest rivals, all within 1% of its average score, shows it competes directly with processors like the AMD Ryzen Embedded V2546, the AMD Ryzen 3 7320C, the Intel Core 7 160UL, and the Intel Core i5-10400F. Its 15-watt TDP and mobile classification also make it the appropriate choice for low-power systems where the 65-watt Intel part would not fit.

The Intel Core 7 251E wins on every recorded specification category. Its 24 cores and 32 threads provide a 6x core count and 8x thread count advantage over the AMD part. The 5.60 GHz boost clock is 1.9 GHz higher. The 36 MB shared L3 cache is 9 times larger. The 89.6 GB/s memory bandwidth is more than double the AMD figure, and the support for DDR5 and ECC memory adds capabilities the AMD chip lacks. PCIe Gen 5 with 16 lanes exceeds the AMD Gen 3 implementation. The desktop market segment and 65-watt TDP indicate it is designed for sustained high-throughput workloads where power draw is not the primary constraint.

The use-case split follows the data. The AMD Ryzen 5 3501U suits mobile platforms that need verified, mid-tier performance within a 15-watt envelope. The Intel Core 7 251E suits desktop platforms that require high core counts, large cache, fast memory, and modern PCIe connectivity, with the caveat that its benchmark scores remain unmeasured in the database.
