Architecture Differences

The AMD Ryzen AI 9 HX 375 is built on the Zen 5 architecture with the Strix Point codename, belonging to the Ryzen AI 300 generation. It uses a hybrid configuration of Zen 5 and Zen 5c cores. The chip is fabricated on a 4 nm process at TSMC, with a die size of 233 mm². The processor uses AMD Socket FP8 and supports DDR5 and LPDDR5X memory. Its cache hierarchy includes 80 KB of L1 per core, 1 MB of L2 per core, and 16 MB of L3 cache. The integrated graphics are Radeon 890M. PCIe support is Gen 4 with 16 lanes from the CPU.

The Intel Core 7 251E uses the Bartlett Lake codename from the Core 7 generation. It is built on a 10 nm process at Intel's foundry, with a die size of 257 mm². The processor uses Intel Socket 1700 and supports both DDR4 and DDR5 memory. Cache amounts include 80 KB of L1 per core, 2 MB of L2 per core, and 36 MB of shared L3 cache. Integrated graphics are UHD Graphics 770. PCIe support is Gen 5 with 16 lanes from the CPU. The Intel part also supports ECC memory, a feature absent from the AMD chip.

The manufacturing process difference is substantial: the AMD part uses half the node size of the Intel part, which typically allows for better power efficiency per transistor. The Intel chip compensates with a larger L3 cache (36 MB vs 16 MB) and double the L2 cache per core (2 MB vs 1 MB). The AMD chip has a smaller die despite having fewer cores, reflecting the denser 4 nm process.

Memory bandwidth is identical at 89.6 GB/s for both, as both use dual-channel memory buses. The Intel part supports a wider range of memory types including older DDR4, while the AMD part is limited to newer DDR5 and LPDDR5X.

The PCIe generation differs significantly: Intel provides Gen 5 lanes while AMD provides Gen 4 lanes. This gives the Intel platform potentially double the interconnect bandwidth for compatible devices.

Head-to-Head Benchmarks

The database does not contain direct head-to-head benchmark comparisons between these two specific processors. The AMD Ryzen AI 9 HX 375 has an extensive benchmark record, while the Intel Core 7 251E has no recorded benchmark scores in the database.

For the AMD part, Cinebench R23 results show a multicore score of 21812 and a singlecore score of 1988. In Cinebench R15, the multicore score is 3334 and singlecore is 301. Geekbench results indicate a multicore score of 13957 and a singlecore score of 2084.

Passmark results for the AMD chip include multithread at 32916, single thread at 3867, integer math at 121754, floating point math at 75153, data encryption at 20802, data compression at 404918, extended instructions at 29269, find prime numbers at 122, physics at 1819, and random string sorting at 44552.

The Intel Core 7 251E has an average benchmark score of 0 in the database, meaning no performance data has been recorded. The AMD chip has an average benchmark score of 46030 and sits at the 89th percentile among all CPUs.

Without recorded scores for the Intel part, the database cannot establish a performance delta between the two. The head-to-head comparison remains incomplete until benchmark data for the Intel Core 7 251E is collected and processed.

The Verdict

The recorded data shows a clear asymmetry: the AMD Ryzen AI 9 HX 375 has an average benchmark score of 46030 with a 89th percentile ranking, while the Intel Core 7 251E has an average benchmark score of 0 with a 50th percentile ranking. These figures reflect the absence of benchmark data for the Intel part rather than its actual performance capability.

The AMD processor is an established mobile part with verified performance across multiple test suites. Its scores in Cinebench R23 multicore (21812) and Geekbench multicore (13957) place it firmly among high-performing mobile processors, ranking at the 89th percentile of all CPUs.

The Intel Core 7 251E is a desktop processor with a higher core count (24 vs 12), higher boost clock (5.60 GHz vs 5.10 GHz), larger L3 cache (36 MB vs 16 MB), and PCIe Gen 5 support. These architectural advantages suggest potential for strong performance, but the database contains no measured results to confirm this.

Users seeking a processor with verified performance data should consider the AMD Ryzen AI 9 HX 375. Users requiring ECC memory support, PCIe Gen 5 connectivity, or a desktop form factor should evaluate the Intel Core 7 251E based on its architectural specifications. The Intel part also supports both DDR4 and DDR5 memory, offering more flexible upgrade paths.

The production status for both processors is Active, indicating ongoing availability. The Intel part has a launch MSRP of $384.

Where Each One Wins

The AMD Ryzen AI 9 HX 375 wins in power efficiency, as indicated by its 28 W TDP compared to the Intel part's 65 W TDP. This makes it suitable for mobile devices where thermal and power constraints are critical. The AMD chip also benefits from a smaller process node (4 nm vs 10 nm), which typically enables better performance per watt. Its Radeon 890M integrated graphics may provide stronger GPU performance compared to the UHD Graphics 770, though the database contains no direct graphics benchmarks for either part.

The Intel Core 7 251E wins on raw core count with 24 cores versus 12, offering more parallel processing capacity. Its higher boost clock of 5.60 GHz provides an advantage for single-threaded bursts. The larger L3 cache (36 MB vs 16 MB) and double L2 cache per core (2 MB vs 1 MB) may improve cache-sensitive workloads. ECC memory support makes it appropriate for data integrity applications. PCIe Gen 5 connectivity offers higher bandwidth for storage and expansion devices. The desktop form factor allows for more robust cooling solutions, which can sustain higher performance levels over extended periods.

For mobile productivity workloads, the AMD processor has verified benchmark scores that place it at the 89th percentile among all CPUs. The recorded data shows particularly strong results in multithreaded tests (Cinebench R23 multicore score of 21812) and memory-intensive operations (Passmark data compression score of 404918).

For desktop compute tasks, the Intel processor offers architectural features conducive to heavy workloads: 32 threads, 36 MB of shared L3 cache, and Gen 5 PCIe lanes. The lack of benchmark data means its measured performance remains unverified in the database, but its specifications indicate capability for multi-threaded processing, server-like error correction, and high-bandwidth peripheral connectivity.
