Intel's nearest rivals include the Intel Core Ultra 7 265H at 41621 (0.1% ahead), the Intel Core i7-14650HX at 41576 (0.2% ahead), and the Intel Core i7-14700T at 41914 (0.6% behind that rival). The average scores place both processors in the same competitive tier despite their very different architectural approaches.

Architecture Differences

The two processors come from different manufacturers, process nodes, and design philosophies. The AMD Ryzen AI 9 HX 375 uses the Zen 5 architecture with the Strix Point codename, belonging to the Ryzen AI 300 generation that combines Zen 5 and Zen 5c cores. It is built on a 4 nm process by TSMC with a die size of 233 mm². The Intel Core 7 251TE uses the Bartlett Lake codename in the Core 7 generation and is built on a 10 nm process by Intel with a die size of 215 mm².

Core counts differ substantially. AMD provides 12 cores and 24 threads, while Intel provides 24 cores and 32 threads. AMD's base clock is 2.00 GHz with a boost clock of 5.10 GHz. Intel's base clock is 1.40 GHz with a boost clock of 5.40 GHz. The higher Intel boost clock helps explain the single-core benchmark dominance, while the higher AMD base clock contributes to its consistent multicore performance in several tests.

Cache structures also differ. Both use 80 KB of L1 cache per core. AMD uses 1 MB of L2 cache per core and a 16 MB L3 cache. Intel uses 1.25 MB of L2 cache per core and a 36 MB shared L3 cache. The larger Intel L3 cache is a notable difference for workloads that benefit from larger shared pools.

Memory support diverges. AMD supports DDR5 and LPDDR5X memory, while Intel supports DDR4 and DDR5. Both use a dual-channel memory bus and the recorded memory bandwidth is identical at 89.6 GB/s. Intel supports ECC memory, while AMD does not. PCIe support also differs: AMD uses Gen 4 with 16 lanes (CPU only), while Intel uses Gen 5 with 16 lanes (CPU only). The integrated graphics are different as well. AMD uses the Radeon 890M, while Intel uses UHD Graphics 770.

The thermal design power values differ significantly. AMD is rated at 28 W, while Intel is rated at 45 W. The socket types are incompatible: AMD uses AMD Socket FP8, and Intel uses Intel Socket 1700. AMD's market segment is mobile, while Intel's is desktop. AMD's release date is 2024-06-30, and Intel's is 2025-01-12. Intel's launch MSRP is $384. Neither processor has an unlocked multiplier. AMD's part number is 100-000001682, and Intel's part number is SRQAXQ5ZG.

Where Each One Wins

The benchmark results indicate distinct strengths that map to different workload categories. AMD's 72.4% lead in PassMark extended instructions makes it the clear choice for applications that use advanced instruction sets, such as encryption accelerators, media codecs, or scientific libraries that dispatch specialized CPU instructions. The 21.1% lead in data compression and the 12.4% lead in random string sorting point to strong performance in archiving, database operations, and text processing. The 29.6% lead in Cinebench R15 multicore and the 9.6% lead in PassMark multithread show that AMD handles heavily threaded rendering and general parallel workloads well.

Intel's 44.8% lead in Cinebench R23 single-core is the standout result. For lightly threaded applications like legacy productivity software, spreadsheet calculations, or older games that depend on a single fast core, Intel delivers substantially more performance. The 16.9% lead in Cinebench R15 single-core reinforces this. Intel's 14.5% lead in Cinebench R23 multicore is interesting because it contradicts the Cinebench R15 multicore result. The newer Cinebench version scales differently with Intel's architecture, suggesting that modern render workloads may favor the Intel chip. The 12.2% lead in floating point math and the 3.2% lead in integer math show that Intel handles raw arithmetic workloads well, including simulation and number-crunching tasks. Intel also leads in data encryption by 6.2%, in physics by 6.1%, and in find prime numbers by 12.9%.

The two processors also differ in platform context. AMD is a mobile part with a 28 W TDP, suitable for thin laptops or compact mobile workstations. Intel is a desktop part with a 45 W TDP, targeting conventional desktop builds with the Intel Socket 1700 platform. The Intel chip's support for ECC memory and its Gen 5 PCIe lanes make it more appropriate for workstation-class desktop systems where memory reliability and high-bandwidth peripherals matter. AMD's LPDDR5X memory support and smaller process node align with power-sensitive mobile designs.

The Verdict

The data shows two processors optimized for different priorities. The AMD Ryzen AI 9 HX 375 delivers superior performance in extended instructions, data compression, random string sorting, and PassMark multithread, with a 72.4% margin in the extended instructions test being the largest single difference in the entire comparison. It also holds a slight edge in PassMark single-thread performance at 8.4%. The 28 W TDP and mobile socket position it as the choice for portable systems that still need high multicore throughput.

The Intel Core 7 251TE dominates single-core Cinebench results by a wide margin, with a 44.8% lead in R23 single-core, and also wins the Cinebench R23 multicore test by 14.5%. Its advantages in floating point math, integer math, physics, data encryption, and prime number finding make it the stronger option for desktop workloads that mix single-thread responsiveness with heavy arithmetic. The 45 W TDP, Intel Socket 1700, DDR4 support, ECC memory capability, and Gen 5 PCIe lanes make it a desktop workstation part.

The recorded average benchmark scores place AMD slightly ahead overall at 46030 versus 41650, but the percentile rankings are close at 89 versus 88. The choice depends on the use case. For mobile systems where power efficiency and specialized instruction throughput matter, AMD is the data-supported pick. For desktop builds where single-core speed, modern Cinebench scaling, and ECC memory support are priorities, Intel is the data-supported pick. Both processors sit in a comparable performance tier, but their architectural differences create clearly separated strengths.
