AMD Ryzen 9 9850HX vs Intel Core 7 251E Comparison

Where Each One Wins

The benchmark data splits these two processors into very different competitive positions. The AMD Ryzen 9 9850HX has a full set of recorded PassMark results across eleven workloads, while the Intel Core 7 251E has no benchmark entries in the database. This means the Ryzen 9 9850HX carries all measured performance data, and the Core 7 251E must be evaluated on architectural specifications alone.

The Ryzen 9 9850HX records its strongest showing in multi-threaded throughput with a PassMark multi-thread score of 51,722. The single-thread result reaches 4,461, placing it in the 97th percentile of all CPUs tracked by the database. The average benchmark score for the AMD part is 106,413, which places it 0.2% ahead of the Intel Xeon w7-3555 and 0.5% ahead of the Intel Xeon 6521P. Against the Intel Xeon w7-2595X, the Ryzen 9 9850HX trails by 2.1%, and it leads the AMD EPYC 8324P by 3%.

The Intel Core 7 251E, by contrast, has an average benchmark score of zero and sits in the 50th percentile. With no recorded workload results, the database cannot assign it any wins in the individual PassMark tests. The Core 7 251E does bring a higher boost clock of 5.60 GHz versus 5.20 GHz on the Ryzen, and it has more physical cores, but those specifications do not translate into measured benchmark victories in the available data.

Architecture Differences

The two chips come from different manufacturing and design lineages. The AMD Ryzen 9 9850HX uses the Zen 5 architecture under the Fire Range codename, built on a 4 nm process at TSMC. The Intel Core 7 251E uses the Bartlett Lake codename on a 10 nm process at Intel's own foundry. The transistor count for the AMD chip is 16,630 million across a die size of 2x 70.6 mm², while the Intel chip lists no transistor count but has a die size of 257 mm².

Core and thread counts differ substantially. The Ryzen 9 9850HX has 12 cores and 24 threads, while the Core 7 251E has 24 cores and 32 threads. The Intel part has twice the physical core count but only eight additional threads, indicating a mix of performance and efficiency cores in the Bartlett Lake design. Both processors dedicate 80 KB of L1 cache per core. The L2 cache per core is 1 MB on the AMD side and 2 MB on the Intel side. The L3 cache is 64 MB on the Ryzen 9 9850HX versus 36 MB shared on the Core 7 251E.

Memory support differs as well. The Ryzen 9 9850HX supports DDR5 only, while the Core 7 251E supports both DDR4 and DDR5. Both run dual-channel memory buses with identical peak memory bandwidth of 89.6 GB/s. Both support ECC memory. PCIe connectivity favors the AMD part with Gen 5 across 28 CPU lanes, while the Intel part offers Gen 5 across 16 CPU lanes. The Ryzen 9 9850HX integrates a Radeon 610M graphics unit, and the Core 7 251E integrates UHD Graphics 770.

The market segments also differ. The Ryzen 9 9850HX is a mobile processor on AMD Socket FL1, while the Core 7 251E is a desktop processor on Intel Socket 1700. The Ryzen 9 9850HX has an unlocked multiplier, whereas the Core 7 251E is locked. The AMD part lists a TDP of 55 watts, and the Intel part lists 65 watts. Both chips remain in active production, with release dates in January 2025: the Ryzen 9 9850HX on January 5, 2025, and the Core 7 251E on January 12, 2025.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark entries between the AMD Ryzen 9 9850HX and the Intel Core 7 251E. The Ryzen 9 9850HX, however, has eleven recorded PassMark results that establish its performance profile. The Intel Core 7 251E has zero recorded results, so no direct score comparisons are possible from the measured data.

The Ryzen 9 9850HX delivers a multi-thread score of 51,722, a floating point math score of 115,062, and an integer math score of 172,943. In extended instructions it scores 53,817, in data compression 662,381, and in data encryption 32,139. The prime number search workload returns 323, physics 3,054, and random string sorting 70,175. The single-thread score appears twice in the data at 4,461.

Without any recorded numbers for the Core 7 251E, the database can only state that the Ryzen 9 9850HX holds all measurable wins by default. The Intel part's 5.60 GHz boost clock and larger core count do suggest a different performance envelope, but the absence of benchmark data prevents any quantitative head-to-head conclusion. The nearest rivals for the Ryzen 9 9850HX are all server-class processors, which places its measured performance in a high-end context. The Core 7 251E's 50th percentile ranking with no average score indicates that the database has not yet recorded enough data to place it competitively.

The Verdict

The recorded data places the AMD Ryzen 9 9850HX as the only one of the two with measurable benchmark performance. Its 97th percentile ranking, average score of 106,413, and leadership over the Intel Xeon w7-3555 by 0.2%, the Intel Xeon 6521P by 0.5%, and the AMD EPYC 8324P by 3% establish a strong measured baseline. The only rival in its nearest group that beats it is the Intel Xeon w7-2595X by 2.1%.

The Intel Core 7 251E cannot be placed by benchmark data. Its 50th percentile and zero average score mean the database has no recorded performance for it. Its specifications, including 24 cores, 32 threads, 5.60 GHz boost, and 36 MB of shared L3 cache, provide a structural profile but no measured results. The Ryzen 9 9850HX counters with 64 MB of L3 cache, a 4 nm TSMC process, 28 PCIe Gen 5 lanes, and an unlocked multiplier.

For users selecting strictly by recorded database performance, the AMD Ryzen 9 9850HX is the only option with data supporting a verdict. For users evaluating specifications alone, the Intel Core 7 251E offers double the core count and a higher boost clock, but those figures carry no benchmark confirmation in the database. The Ryzen 9 9850HX also holds advantages in cache capacity, process node, PCIe lane count, and overclocking flexibility. The Core 7 251E holds advantages in core count, thread count, boost clock, and memory type flexibility with DDR4 and DDR5 support.
