AMD Ryzen AI 9 HX 375 vs Intel Core i5-14600T Comparison

Head-to-Head Benchmarks

The recorded data shows a clear split: the AMD Ryzen AI 9 HX 375 wins 12 of 17 head-to-head comparisons, while the Intel Core i5-14600T takes 5. But the margins tell a more nuanced story than the win count alone.

The AMD processor's largest victory comes in PassMark extended instructions, where it scores 29,269 against Intel's 16,985, a 72.3% advantage. That gap indicates a substantial difference in SIMD and AVX-512 style workloads, which typically benefit from wider execution resources. Data compression also favors AMD heavily: 404,918 versus 301,827, a 34.2% lead. Integer math follows at 121,754 versus 95,112, a 28% edge, and random string sorting shows a 29.9% advantage (44,552 versus 34,310). Multithreaded PassMark lands at 32,916 versus 26,409, a 24.6% win for AMD.

Cinebench R15 multicore is another decisive AMD win: 3,334 versus 2,262, a 47.4% margin. Geekbench multicore also goes to AMD at 13,957 versus 12,840, an 8.7% lead. Floating point math (75,153 versus 64,726, 16.1%), data encryption (20,802 versus 18,226, 14.1%), and PassMark single-thread (3,867 versus 3,744, 3.3%) all favor AMD as well. The find-prime-numbers test is nearly a tie at 122 versus 121, a 0.8% edge for AMD.

The Intel processor's wins are concentrated in single-core and lightly threaded tests, but they are not uniform. Cinebench R23 single-core shows Intel at 3,169 versus 1,988, a massive 37.3% advantage. Geekbench single-core gives Intel 2,559 versus 2,084, an 18.6% lead. Cinebench R15 single-core is closer: 319 versus 301, a 5.6% edge for Intel. Cinebench R23 multicore surprisingly goes to Intel at 22,447 versus 21,812, a 2.8% margin, despite AMD winning R15 multicore. PassMark physics also favors Intel slightly at 1,873 versus 1,819, a 2.9% gap.

The pattern suggests AMD's Zen 5 design excels in sustained throughput and vector-heavy tasks, while Intel's Raptor Lake cores deliver stronger per-thread performance in Cinebench and Geekbench single-core workloads. The R23 multicore result for Intel is an outlier relative to other multicore scores, possibly reflecting thermal or power behavior specific to that benchmark.

Where Each One Wins

The AMD Ryzen AI 9 HX 375 dominates in workloads that stress sustained multicore execution and vector math. Data compression, encryption, extended instructions, integer math, floating point math, multithreaded PassMark, random string sorting, and Geekbench multicore all favor AMD. The 47.4% lead in Cinebench R15 multicore and the 72.3% lead in extended instructions point to a processor that handles heavy parallel compute with ease. Its 24 threads give it an edge in thread-saturated tasks, and the 4 nm process at 28 W TDP suggests strong efficiency for mobile use. The Radeon 890M integrated graphics also position it for systems that need capable on-die graphics without a discrete GPU.

The Intel Core i5-14600T wins in single-core and lightly threaded applications. Geekbench single-core at 2,559 versus 2,084 and Cinebench R23 single-core at 3,169 versus 1,988 are clear Intel advantages. PassMark physics also goes to Intel, and Cinebench R23 multicore shows Intel ahead by a small margin. The 14 physical cores and 24 MB of shared L3 likely help in mixed workloads that do not fully saturate all threads. Desktop orientation with DDR4 support and ECC memory gives Intel a flexibility edge in systems where memory compatibility or error-correcting memory matters. The Gen 5 PCIe support also provides higher bandwidth for expansion cards, though no benchmark data quantifies that advantage here.

The Verdict

The data indicates that the AMD Ryzen AI 9 HX 375 is the stronger choice for compute-heavy multitasking, vector workloads, and scenarios where power efficiency matters. Its 12 wins out of 17 comparisons, including dominant margins in extended instructions and data compression, make it the superior throughput processor. The 89th percentile ranking against all CPUs, compared to Intel's 83rd, reinforces this position. The average benchmark score of 46,030 for AMD versus 32,707 for Intel shows a 40.7% overall gap in the recorded measurements.

The Intel Core i5-14600T is the better option for single-threaded responsiveness and desktop-specific features. Its Cinebench R23 single-core score of 3,169 is 37.3% higher than AMD's, and Geekbench single-core shows an 18.6% advantage. The support for DDR4 and ECC memory, along with Gen 5 PCIe, makes it a more flexible desktop platform. The 14-core count and 24 MB of shared L3 give it an edge in Cinebench R23 multicore, though this does not translate to wins in other multicore tests. Users prioritizing peak single-core performance or needing ECC memory should select the Intel part. Those who need maximum multicore throughput, vector math, or a mobile-friendly 28 W TDP should choose the AMD Ryzen AI 9 HX 375.
