AMD Ryzen AI 7 350 vs Intel Core i5-14500HX Comparison

Where Each One Wins

The benchmark database splits these two mobile processors into distinct roles. The Intel Core i5-14500HX wins 11 of the 17 recorded head-to-head comparisons, while the AMD Ryzen AI 7 350 takes 6. That raw tally, however, hides a more interesting story about workload character.

Intel’s chip dominates sustained multi-threaded rendering workloads. In Cinebench R23 multi-core, the i5-14500HX scores 24,234 against AMD’s 16,014.5, a 51.3% advantage. That is the single largest gap in the entire comparison. The same pattern appears in Cinebench R15 multi-core, though the margin collapses to just 1.4% in AMD’s favor there (2,477 vs 2,442). The R23 result is the more reliable indicator of long-form rendering performance.

The Intel part also sweeps the PassMark math and physics categories. Floating point math shows a 30.5% lead (69,442 vs 53,230), integer math is 11.6% ahead (95,584 vs 85,651), and the physics test shows a 41.7% gap (1,911 vs 1,349). Prime number finding is likewise heavily Intel-favored at 62.5% (130 vs 80). Data encryption favors Intel by 27.9% (19,502 vs 15,244), while data compression is closer at 9.8% (333,851 vs 304,089). Random string sorting lands at 8.9% (36,219 vs 33,266).

AMD’s wins are concentrated in Geekbench and single-thread PassMark tests. The Ryzen AI 7 350 takes Geekbench multi-core by 12.9% (11,676 vs 10,171) and Geekbench single-core by 1.6% (2,164 vs 2,129). PassMark single-thread goes to AMD by 5.3% (3,834 vs 3,629). The extended instructions test also favors AMD by 7.7% (21,678 vs 20,019).

The use-case split is clear. Intel is the choice for rendering, physics simulation, encryption, and heavy math workloads. AMD is better for Geekbench-style mixed workloads and single-threaded responsiveness, but its wins are narrower. The largest AMD victory is 12.9%, while Intel’s biggest is 74.7% in Cinebench R23 single-core. That asymmetry matters.

Architecture Differences

The two chips come from fundamentally different design philosophies. Intel’s Core i5-14500HX is built on Raptor Lake architecture, produced on Intel’s 10 nm process with a die size of 257 mm². AMD’s Ryzen AI 7 350 uses Zen 5 architecture with a 4 nm TSMC process and a 195 mm² die. The Intel part is physically larger and uses a more mature process node.

Core counts diverge sharply. Intel fields 14 cores and 20 threads, while AMD offers 8 cores and 16 threads. The Intel design relies on a hybrid configuration typical of Raptor Lake-HX, combining performance and efficiency cores. AMD’s Krackan Point uses a Zen 5 / Zen 5c hybrid arrangement, though the database does not break down core types for either chip.

Cache hierarchies differ in total capacity. Intel allocates 24 MB of shared L3 cache, with 2 MB of L2 per core and 80 KB of L1 per core. AMD has 8 MB of L3, 1 MB of L2 per core, and the same 80 KB of L1 per core. The Intel chip’s larger L3 is consistent with its multi-threaded strengths, while AMD’s smaller cache per core is offset by higher single-thread efficiency.

Memory support separates the two. Intel supports both DDR4 and DDR5 in dual-channel mode, and includes ECC memory support. AMD supports DDR5 and LPDDR5X in dual-channel mode, with a rated memory bandwidth of 89.6 GB/s, but no ECC. PCIe connectivity also differs: Intel offers Gen 5 with 16 CPU lanes, AMD offers Gen 4 with 16 CPU lanes.

Integrated graphics favor AMD. The Ryzen AI 7 350 carries a Radeon 860M, while Intel ships UHD Graphics 770. The database does not provide graphics benchmarks, so no performance comparison is possible from the recorded data.

Power envelopes differ meaningfully. Intel has a 55 W TDP, AMD a 28 W TDP. That 27 W gap explains much of the performance differential in sustained loads. Intel trades power for throughput; AMD trades throughput for efficiency. The unlocked multiplier on Intel (true) versus locked on AMD (false) further separates their positioning.

FAQ

Q: Which processor is faster in multi-core rendering?

A: The Intel Core i5-14500HX leads by a wide margin in Cinebench R23 multi-core, scoring 24,234 versus AMD’s 16,014.5, a 51.3% advantage. In Cinebench R15 multi-core, AMD edges ahead by 1.4% with 2,477 versus 2,442.

Q: Does the AMD chip win any single-threaded tests?

A: Yes. The Ryzen AI 7 350 wins PassMark single-thread by 5.3% (3,834 vs 3,629) and Geekbench single-core by 1.6% (2,164 vs 2,129). However, Intel wins Cinebench R23 single-core by 74.7% (3,421 vs 1,958) and Cinebench R15 single-core by 17% (344 vs 294).

Q: What explains Intel’s large Cinebench single-core lead over AMD?

A: The recorded data shows Intel scoring 3,421 in Cinebench R23 single-core versus AMD’s 1,958. This 74.7% gap is unusual given AMD’s wins in other single-thread tests, suggesting workload-specific behavior in Cinebench’s rendering engine rather than a general single-core superiority.

Q: Which chip has more cores and threads?

A: Intel has 14 cores and 20 threads. AMD has 8 cores and 16 threads. Intel’s extra 6 cores and 4 threads contribute to its multi-threaded benchmark wins.

Q: How do the power requirements compare?

A: Intel has a 55 W TDP, while AMD has a 28 W TDP. AMD’s lower power draw aligns with its 4 nm process and smaller die, though the database does not include efficiency-per-watt measurements.

Q: Is there a difference in memory bandwidth?

A: AMD lists a memory bandwidth of 89.6 GB/s with DDR5 and LPDDR5X support. Intel supports DDR4 and DDR5 but the database does not record a bandwidth figure for it.

Head-to-Head Benchmarks

The biggest Intel victory comes in Cinebench R23 single-core, where the i5-14500HX scores 3,421 against AMD’s 1,958. That 74.7% delta is the largest in the entire dataset. The same test in multi-core shows Intel ahead by 51.3% (24,234 vs 16,014.5). These two results establish Intel’s dominance in Cinebench’s rendering workload regardless of thread count.

PassMark physics shows Intel ahead by 41.7% (1,911 vs 1,349), a strong indicator for simulation and game physics workloads. Floating point math follows at 30.5% (69,442 vs 53,230), and data encryption at 27.9% (19,502 vs 15,244). Prime number finding rounds out the top Intel wins at 62.5% (130 vs 80). These are not marginal victories; they represent substantial performance deltas.

AMD’s largest win is Geekbench multi-core at 12.9% (11,676 vs 10,171). That is a meaningful lead in a mixed workload benchmark that combines memory, integer, and floating point tasks. Geekbench single-core goes to AMD by a slim 1.6% (2,164 vs 2,129). PassMark single-thread shows AMD ahead by 5.3% (3,834 vs 3,629), and extended instructions by 7.7% (21,678 vs 20,019).

The Cinebench R15 multi-core result is an outlier. AMD wins 2,477 to 2,442, a 1.4% margin, despite losing R23 multi-core by 51.3%. This inconsistency suggests the older R15 test does not scale with Intel’s core count the same way R23 does. The R15 single-core test, however, goes to Intel by 17% (344 vs 294).

PassMark multi-thread shows Intel ahead by 14.3% (28,508 vs 24,935), a solid but not overwhelming lead. Data compression favors Intel by 9.8% (333,851 vs 304,089), and random string sorting by 8.9% (36,219 vs 33,266). Integer math goes to Intel by 11.6% (95,584 vs 85,651).

The overall average benchmark scores place both chips at the 84th percentile of all CPUs. Intel’s average is 35,094, AMD’s is 34,222. Intel’s nearest rival is the Core i9-12900HX at 35,003 (0.3% ahead), while AMD’s nearest rival is the EPYC 4244P at 34,220 (essentially tied). Both parts sit in the upper tier of mobile processors, but Intel’s wins are broader and deeper across the workload spectrum.
