Architecture Differences

The AMD Ryzen AI 9 HX 470 uses the Zen 5 architecture under the Gorgon Point codename, belonging to the Ryzen AI 400 generation that combines Zen 5 and Zen 5c cores. It is fabricated by TSMC on a 4 nm process with a die size of 233 mm². The Intel Core 7 251E belongs to the Bartlett Lake generation and is fabricated by Intel on a 10 nm process with a die size of 257 mm².

Cache configurations differ substantially. Both processors allocate 80 KB of L1 cache per core, but the AMD part has 1 MB of L2 cache per core, while the Intel part has 2 MB per core. The L3 cache differs even more: the AMD chip has 16 MB, while the Intel chip has 36 MB shared. This gives the Intel processor a larger total cache footprint for data-heavy workloads.

Memory support diverges in both type and ECC capability. The AMD processor handles DDR5 and LPDDR5X, while the Intel processor handles DDR4 and DDR5. ECC memory support appears only on the Intel side, which matters for workstation and server-adjacent use cases. Both parts run dual-channel memory with identical 89.6 GB/s bandwidth.

PCIe capabilities differ by generation. The AMD Ryzen AI 9 HX 470 provides Gen 4 with 16 CPU lanes, while the Intel Core 7 251E provides Gen 5 with 16 CPU lanes. The Intel part doubles the PCIe bandwidth potential for high-speed storage and expansion cards.

Integrated graphics also differ. The AMD chip uses Radeon 890M graphics, while the Intel chip uses UHD Graphics 770. The AMD solution is typically aimed at more demanding integrated graphics tasks, though the database does not include direct graphics benchmark comparisons.

Power envelopes differ significantly. The AMD Ryzen AI 9 HX 470 has a 28 W TDP, while the Intel Core 7 251E has a 65 W TDP. The Intel part draws more power but offers more cores, a higher boost clock, and a faster PCIe generation. The AMD part achieves its results within a much tighter power budget.

The Verdict

The recorded data shows two processors with very different design goals. The AMD Ryzen AI 9 HX 470 sits at the 92nd percentile among all CPUs, with an average benchmark score of 58,826. The Intel Core 7 251E sits at the 50th percentile with an average benchmark score of 0, meaning the database contains no recorded average score for it. This makes direct percentile comparison impossible.

For mobile users who need strong single-threaded and multi-threaded performance within a 28 W power envelope, the AMD Ryzen AI 9 HX 470 is the clear choice. It delivers a full benchmark profile with strong Cinebench and PassMark results. The Intel Core 7 251E targets desktop users who need 24 physical cores, ECC memory support, DDR4 compatibility, and Gen 5 PCIe. Its higher 65 W TDP suits desktop cooling solutions.

The Intel part offers more raw cores and threads, a higher boost clock, more L3 cache, and a newer PCIe generation. The AMD part offers a smaller process node, lower TDP, and a complete set of recorded benchmark scores. Users who prioritize power efficiency and validated performance data should choose the AMD chip. Users who need maximum core counts, ECC memory, and desktop platform features should choose the Intel chip.

Where Each One Wins

The AMD Ryzen AI 9 HX 470 wins in power efficiency and validated performance. Its 28 W TDP allows thin-and-light mobile designs, while its 4 nm process node reduces power draw compared to the Intel 10 nm part. The complete benchmark profile confirms strong multi-threaded and single-threaded scores, with the 92nd percentile ranking among all CPUs.

The Intel Core 7 251E wins in raw core count, offering 24 cores and 32 threads versus 12 cores and 24 threads. It also wins in L3 cache capacity with 36 MB versus 16 MB, in boost clock with 5.60 GHz versus 5.20 GHz, and in PCIe generation with Gen 5 versus Gen 4. ECC memory support and DDR4 compatibility give it flexibility for workstation builds.

For mobile productivity, content creation, and general computing with low power draw, the AMD Ryzen AI 9 HX 470 delivers the strongest recorded results. For desktop workloads that scale across many cores, require ECC reliability, or need DDR4 memory support, the Intel Core 7 251E provides the architectural advantages. The Intel part's higher TDP of 65 W suits desktop cooling, while the AMD part's 28 W TDP suits laptops and compact systems.

The database shows no benchmark scores for the Intel Core 7 251E, so its actual performance remains unmeasured. Users who require verified benchmark data should rely on the AMD chip's extensive results. Users who prioritize specifications over measured performance may find the Intel chip's core count and cache capacity compelling.
