AMD Ryzen AI 9 HX 375 vs Intel Core i5-14400 Comparison

Where Each One Wins

The benchmark record splits sharply between these two processors. The AMD Ryzen AI 9 HX 375 takes 15 of the 17 head-to-head tests, while the Intel Core i5-14400 wins only 2. That margin alone tells the primary story, but the nature of each win matters more than the count.

AMD's mobile processor dominates every multicore-heavy workload in the database. The largest gap appears in Cinebench R15 multicore, where the Ryzen AI 9 HX 375 scores 3334 against Intel's 2148, a 55.2% advantage. Geekbench multicore shows a 42.3% lead (13957 versus 9807). PassMark integer math delivers 121754 versus 82017, a 48.4% difference. Prime number finding, extended instructions, and random string sorting all fall in AMD's favor by margins between 37.7% and 52.5%.

The Intel part wins in two specific areas: single-core Cinebench tests. In Cinebench R15 single-core, Intel scores 303 against AMD's 301, a razor-thin 0.7% edge. The R23 single-core result is more decisive: Intel posts 3009 versus AMD's 1988, a 33.9% advantage. That R23 gap is the largest single test differential in either direction, and it reveals a notable divergence in how each chip handles lightly threaded rendering workloads.

The remaining single-thread tests do not follow Intel's lead. Geekbench single-core goes to AMD at 2084 versus 1905 (9.4% ahead). PassMark single-thread also favors AMD at 3867 versus 3741 (3.4% ahead). So Intel's single-core wins are confined to the Cinebench rendering suite, while AMD claims the broader single-thread performance picture across other test families.

Architecture Differences

The two chips come from fundamentally different design philosophies and market segments. AMD's Ryzen AI 9 HX 375 is a mobile processor on AMD Socket FP8, built on TSMC's 4 nm process with a 28 W TDP. Intel's Core i5-14400 is a desktop part on Intel Socket 1700, fabricated on Intel's 10 nm node with a 65 W TDP. The process node gap alone explains part of the efficiency and thermal envelope difference.

AMD uses the Zen 5 architecture under the Strix Point codename, part of the Ryzen AI 300 generation that mixes Zen 5 and Zen 5c cores. The chip packs 12 cores and 24 threads. Intel counters with Raptor Lake, specifically Raptor Lake-R, from the Core 14th Gen family, offering 10 cores and 16 threads. That two-core and eight-thread deficit matters heavily in parallel workloads.

Cache layouts differ substantially. Both share 80 KB of L1 per core. AMD provides 1 MB of L2 per core and 16 MB of L3. Intel provides 1.25 MB of L2 per core and a larger 20 MB shared L3. Despite Intel's larger L3 pool, AMD's overall benchmark record suggests its cache hierarchy serves its core layout better in the tested scenarios.

Memory support also diverges. AMD supports DDR5 and LPDDR5X with dual-channel access and a measured 89.6 GB/s bandwidth. Intel supports DDR4 and DDR5, also dual-channel, but the database records no bandwidth figure for it. Intel does support ECC memory, while AMD does not. PCIe generations differ as well: AMD runs Gen 4 with 16 CPU lanes, Intel runs Gen 5 with 16 CPU lanes.

Integrated graphics tell another story. AMD ships the Radeon 890M, a substantial integrated GPU for a mobile part. Intel ships UHD Graphics 730, a more modest desktop iGPU. The database does not include graphics benchmarks, so the comparison rests on the spec sheet alone.

The die sizes are close: AMD measures 233 mm², Intel 215 mm². Both processors have locked multipliers, and both are currently marked as Active in production. AMD released on 2024-06-30, Intel on 2024-01-07, roughly six months apart.

The clock speed picture is mixed. Intel starts at a higher 2.50 GHz base but peaks lower at 4.70 GHz. AMD starts at 2.00 GHz base but boosts to 5.10 GHz. The TDP difference is stark: AMD draws 28 W versus Intel's 65 W, a 37 W gap that reflects the mobile versus desktop positioning.

Head-to-Head Benchmarks

The Cinebench R15 multicore result is the single most lopsided comparison in the dataset. AMD's 3334 score beats Intel's 2148 by 55.2%. That is not a marginal win; it is a category-level difference. The same test in single-core flips, with Intel at 303 versus AMD's 301, but the 2-point margin is nearly a tie.

Cinebench R23 presents a more nuanced picture. In multicore, AMD wins narrowly at 21812 versus 21315, only 2.3% ahead. In single-core, Intel wins decisively at 3009 versus 1988, a 33.9% blowout. This suggests Intel's Raptor Lake architecture handles lightly threaded rendering with exceptional efficiency, while AMD's higher core count carries the day only when all threads engage.

Geekbench results favor AMD in both modes. Multicore shows AMD at 13957 against Intel's 9807, a 42.3% lead. Single-core shows AMD at 2084 versus 1905, a 9.4% edge. These results diverge from the Cinebench single-core pattern, indicating that Intel's single-core advantage is workload-specific rather than universal.

The PassMark suite offers the broadest coverage. AMD wins every single PassMark category. The closest is single-thread at 3.4% (3867 versus 3741). The widest is integer math at 48.4% (121754 versus 82017). Extended instructions show a 47.7% gap (29269 versus 19816). Prime number finding shows 52.5% (122 versus 80). Data compression, encryption, floating point, multithread, physics, and random string sorting all land between 22.1% and 37.7% in AMD's favor.

The overall average benchmark score reinforces the pattern. AMD's average is 46030, placing it at the 89th percentile of all CPUs. Intel's average is 32115, at the 82nd percentile. AMD's nearest rivals in the database include the Intel Core i9-13900HX at 46098 (0.1% ahead), the Intel Core Ultra 5 235 at 46062 (0.1% behind), and the AMD EPYC 4364P at 45970 (0.1% behind). Intel's nearest rivals include the Intel Core i7-12800H at 32121, the Intel Core i7-13705H at 32076, and the Intel Core i5-14450HX at 32040.

The Verdict

The data draws a clear line between these two processors. The AMD Ryzen AI 9 HX 375 is the stronger performer in nearly every recorded test, particularly across multicore, integer math, encryption, compression, and extended instruction workloads. Its 12 cores and 24 threads provide a structural advantage that Intel's 10 cores and 16 threads cannot overcome in parallel tasks. The 55.2% Cinebench R15 multicore margin and the 48.4% integer math gap are not close calls.

The Intel Core i5-14400 holds two specific advantages. First, it wins Cinebench R23 single-core by a wide 33.9% margin, indicating a genuine strength in lightly threaded rendering workloads. Second, it supports ECC memory, which matters for certain professional and server-adjacent use cases. Its higher base clock of 2.50 GHz and larger 20 MB L3 cache contribute to its single-core showing, but the overall benchmark record tilts heavily toward AMD.

The market segment difference is fundamental. AMD's 28 W TDP and mobile socket position it for laptops and compact systems. Intel's 65 W TDP and desktop socket position it for traditional desktop builds. The recorded data shows AMD delivering superior performance across the majority of tests while consuming less than half the TDP budget. The 89th versus 82nd percentile ranking summarizes the overall performance tier gap.

For users prioritizing multicore throughput, encryption, data compression, or floating point math, the AMD Ryzen AI 9 HX 375 is the clear choice based on the recorded scores. For users whose primary workload is single-threaded Cinebench rendering or who require ECC memory support, the Intel Core i5-14400 offers the better fit. The database records no scenario where Intel wins a majority of tests, and its two wins are confined to the Cinebench single-core family.
