Head-to-Head Benchmarks

The database contains no head-to-head benchmark entries for these two processors, meaning there are no direct score comparisons available. The AMD Ryzen 9 8940HX’s nearest rivals provide context for its performance tier, though none of those rivals is the Intel Core 7 251E. The closest competitor by average score is the Intel Xeon w5-3535X at 81115, a 0% delta from the Ryzen 9 8940HX’s 81103. The Intel Core i9-14900KS follows at 81127, also a 0% delta, while the AMD Ryzen AI Max+ PRO 395 trails by 0.4% at 80762. The Intel Xeon 638 sits at 80723, a 0.5% gap. These figures place the Ryzen 9 8940HX in a performance band shared with high-end desktop and workstation parts, but they say nothing about the Core 7 251E. Since the Intel chip has a 50th percentile rank and no average score, the data cannot express how it would fare against the Ryzen 9 8940HX in any specific test. The Ryzen 9 8940HX’s own benchmarks, such as 5355 in Cinebench R15 multi-core and 2104 in PassMark physics, serve as reference points, but no equivalent Intel results exist in the database to set against them.

Specification Differences

The two processors diverge on nearly every core specification. The AMD Ryzen 9 8940HX uses 16 cores and 32 threads, while the Intel Core 7 251E uses 24 cores and 32 threads. Clock behavior differs: the AMD chip starts at 2.40 GHz base and reaches 5.30 GHz boost, whereas the Intel chip starts at 2.10 GHz base and reaches 5.60 GHz boost. Thermal design power also separates them, with the Ryzen 9 8940HX rated at 55 W and the Core 7 251E at 65 W. The AMD processor uses AMD Socket FL1, a mobile platform, while the Intel processor uses Intel Socket 1700, a desktop platform. Memory support is another split: the Ryzen 9 8940HX accepts only DDR5 with a dual-channel bus and 83.2 GB/s bandwidth, while the Core 7 251E accepts DDR4 and DDR5 on a dual-channel bus with 89.6 GB/s bandwidth. ECC memory support exists on the Intel chip but not on the AMD chip. PCIe lane counts differ as well, with the AMD part offering Gen 5 with 28 lanes (CPU only) versus the Intel part’s Gen 5 with 16 lanes (CPU only). Integrated graphics differ: the Ryzen 9 8940HX carries Radeon 610M, and the Core 7 251E carries UHD Graphics 770. The AMD chip has an unlocked multiplier, while the Intel chip does not. Release dates also differ, with the Ryzen 9 8940HX released on 2025-04-22 and the Core 7 251E on 2025-01-12. The Intel part has a launch MSRP of $384, which can be stated once as the launch price; the AMD part has no recorded launch price.

Architecture Differences

The architectural gap between these processors is substantial. The AMD Ryzen 9 8940HX uses Zen 4 architecture under the Dragon Range codename, part of the 8000 series. It is built on a 5 nm process at TSMC, with 13,140 million transistors and a die size of 2x 71 mm². Its cache layout includes 64 KB of L1 per core, 1 MB of L2 per core, and 64 MB of L3. The Intel Core 7 251E uses the Bartlett Lake codename, part of the Core 7 generation, built on a 10 nm process at Intel with a die size of 257 mm². Its cache arrangement provides 80 KB of L1 per core, 2 MB of L2 per core, and 36 MB of shared L3. No transistor count is recorded for the Intel chip. The AMD processor’s larger L3 cache at 64 MB versus 36 MB gives it an advantage in workloads that benefit from large shared caches, while the Intel chip’s smaller process node number, 10 nm versus 5 nm, reflects an older fabrication technology. The Intel part compensates with a larger physical die and more cores. The AMD chip’s mobile-oriented Dragon Range design targets high-end laptops, while the Intel Bartlett Lake chip targets desktop systems. The Ryzen 9 8940HX also has no ECC support, whereas the Core 7 251E does, a feature that aligns with its desktop positioning. The architecture difference also shows in memory flexibility: the Intel chip supports both DDR4 and DDR5, while the AMD chip is limited to DDR5. The Intel chip’s UHD Graphics 770 integrated GPU contrasts with the AMD chip’s Radeon 610M, though neither is a primary focus for a processor with this many cores.

The Verdict

The data supports a clear choice for users who require proven, measured performance: the AMD Ryzen 9 8940HX. Its 95th percentile ranking, average benchmark score of 81103, and comprehensive test results across Cinebench R15, Cinebench R23, and PassMark workloads establish it as a capable processor in the upper tier of all CPUs. Its 16 cores and 32 threads, combined with a 64 MB L3 cache and 5.30 GHz boost clock, suit multi-threaded workloads such as rendering, data processing, and scientific computing. The Intel Core 7 251E offers a different specification set, with 24 cores, 32 threads, a higher 5.60 GHz boost clock, a 65 W TDP, ECC memory support, and compatibility with both DDR4 and DDR5. However, the database records no benchmark scores for this chip, so its real-world performance cannot be verified from the available data. Its 50th percentile rank and average score of 0 are placeholders, not evidence of performance. For builders who prioritize ECC memory, a desktop socket, or a higher base core count, the Core 7 251E presents those features on paper, but the absence of test results means no performance claims can be made for it. The Ryzen 9 8940HX, by contrast, delivers a full set of recorded scores that place it alongside processors like the Intel Xeon w5-3535X and Intel Core i9-14900KS, both within 0% delta of its average score. The verdict from the database is straightforward: the AMD chip has proven performance and a top-tier ranking, while the Intel chip remains an untested specification sheet.
