AMD Ryzen AI 9 HX 375 vs Intel Core i7-14650HX Comparison

Head-to-Head Benchmarks

The benchmark database pits the AMD Ryzen AI 9 HX 375 against the Intel Core i7-14650HX across 17 recorded tests. The final tally is extremely close: AMD takes 9 wins, Intel takes 8. However, the margin of victory matters more than the count, and the data reveals a clear split between workload types.

AMD’s largest win comes in PassMark extended instructions, where the Ryzen AI 9 HX 375 scores 29,269 versus Intel’s 24,150, a 21.2% advantage. This is the single biggest performance gap in either direction. AMD also leads in Cinebench R23 multicore, scoring 21,812 against Intel’s 20,454, a 6.6% edge. The R23 single-core result favors AMD as well, 1,988 to 1,969, though by a slim 1% margin. In PassMark integer math, AMD posts 121,754 versus 116,661, a 4.4% lead. Data compression also goes AMD’s way: 404,918 against 398,418, a 1.6% difference. Random string sorting favors AMD by 3.5%, with scores of 44,552 and 43,035. The single-thread PassMark result is nearly a tie, with AMD at 3,867 and Intel at 3,841, a 0.7% edge for AMD.

Intel’s strongest responses come in different areas. The largest Intel win is PassMark find prime numbers, where it scores 152 versus AMD’s 122, a 19.7% margin. PassMark physics also goes decisively to Intel, 2,202 to 1,819, a 17.4% lead. Floating-point math favors Intel by 11.6%, at 84,999 versus 75,153. Data encryption shows Intel ahead by 9.2%, scoring 22,917 against 20,802. In Cinebench R15 multicore, Intel wins 3,470.5 to 3,334, a 3.9% margin. Geekbench multicore goes Intel’s way by 2%, 14,249 to 13,957, and Geekbench single-core by 4.1%, 2,173 to 2,084. PassMark multithread is a narrow Intel win, 33,495 to 32,916, a 1.7% gap. The R15 single-core test goes to AMD by 5.4%, with 301 versus 285.5.

The pattern is consistent: AMD dominates instruction-heavy, integer, and compression workloads, while Intel excels in physics simulation, prime-number finding, floating-point math, and encryption. The overall average benchmark score reflects this split, with AMD at 46,030 and Intel at 41,576, though the percentile rankings are close: AMD sits at the 89th percentile of all CPUs, Intel at the 88th.

Architecture Differences

The two processors come from fundamentally different design philosophies. AMD’s Ryzen AI 9 HX 375 uses the Zen 5 architecture on the Strix Point codename, built on a 4 nm TSMC process. It integrates both Zen 5 and Zen 5c cores, a hybrid arrangement that combines full-performance cores with compact efficiency cores in the same die. The die measures 233 mm². Intel’s Core i7-14650HX is based on Raptor Lake, specifically the Raptor Lake-HX refresh, fabricated on Intel’s 10 nm process. Its die is larger at 257 mm².

Core counts differ significantly. AMD provides 12 cores and 24 threads. Intel provides 16 cores and 24 threads. Both match on thread count, but Intel does so with more physical cores. The core configuration hints at different scheduling strategies: AMD’s mixed Zen 5 and Zen 5c arrangement versus Intel’s homogeneous Raptor Lake design.

Cache hierarchies diverge as well. Both CPUs have 80 KB of L1 cache per core. AMD’s L2 is 1 MB per core, while Intel’s is 2 MB per core. L3 cache is where Intel takes a clear advantage: 30 MB shared versus AMD’s 16 MB. The larger shared L3 on Intel likely contributes to its floating-point and physics results.

Clock speeds are close. AMD runs a 2.00 GHz base and 5.10 GHz boost. Intel runs a 2.20 GHz base and 5.20 GHz boost. Intel has a slightly higher base and boost, but AMD’s smaller process node allows higher efficiency per clock.

Memory support differs. AMD supports DDR5 and LPDDR5X, with a dual-channel bus and a recorded memory bandwidth of 89.6 GB/s. Intel supports DDR4 and DDR5, also dual-channel, but the database does not record a bandwidth figure for Intel. Intel supports ECC memory; AMD does not. PCIe connectivity also differs: AMD uses Gen 4 with 16 CPU lanes, Intel uses Gen 5 with 16 CPU lanes.

Integrated graphics are not equivalent. AMD ships the Radeon 890M, a substantial integrated GPU. Intel ships UHD Graphics 710, a more basic solution. For systems relying on the iGPU, this is a significant divergence.

The thermal design power (TDP) values are far apart: AMD is rated at 28 watts, Intel at 55 watts. This affects sustained performance in thin laptops versus larger gaming or workstation machines.

FAQ

Q: Which processor wins more benchmark tests?

A: AMD Ryzen AI 9 HX 375 wins 9 of the 17 head-to-head tests. Intel Core i7-14650HX wins 8.

Q: What is the largest single-test performance gap?

A: AMD’s PassMark extended instructions score of 29,269 beats Intel’s 24,150 by 21.2%. Intel’s largest win is PassMark find prime numbers, 152 versus 122, a 19.7% margin.

Q: How do the two compare in multi-threaded rendering workloads?

A: Results are mixed. AMD wins Cinebench R23 multicore by 6.6% (21,812 versus 20,454), but Intel wins Cinebench R15 multicore by 3.9% (3,470.5 versus 3,334). PassMark multithread goes Intel’s way by 1.7%.

The Verdict

The data describes two processors with opposite strengths. The AMD Ryzen AI 9 HX 375 is the choice for instruction-heavy, integer, and compression workloads. Its 21.2% lead in extended instructions and 6.6% lead in Cinebench R23 multicore make it the stronger option for software compilation, data compression, and general productivity that relies on integer math. Its 28-watt TDP also positions it for thinner, more power-conscious mobile designs.

The Intel Core i7-14650HX is the pick for physics simulation, floating-point math, and encryption-heavy tasks. Its 19.7% lead in prime-number finding and 17.4% lead in physics indicate strong raw compute in those specific areas. The 55-watt TDP and 16-core configuration suggest it belongs in larger chassis with more aggressive cooling, where sustained heavy loads are expected.

For single-core responsiveness, the two are essentially tied: AMD leads Cinebench R23 single-core by 1% and PassMark single-thread by 0.7%, while Intel leads Geekbench single-core by 4.1%. Neither dominates all single-threaded tests.

The overall average benchmark score favors AMD at 46,030 versus 41,576, and AMD holds the higher CPU percentile at 89 versus 88. However, the narrow percentile gap indicates both are competitive in the broader CPU landscape. Users should select based on workload: AMD for integer and compression, Intel for floating-point, physics, and encryption.
