AMD Ryzen AI 7 450 vs Intel Core i5-14500HX Comparison

Where Each One Wins

The recorded benchmark data splits these two mobile processors into distinct usage profiles. The AMD Ryzen AI 7 450 takes 4 wins out of 15 head-to-head comparisons, while the Intel Core i5-14500HX takes 11. That raw tally, however, hides which workloads each part actually favors.

The AMD Ryzen AI 7 450 wins in single-threaded PassMark testing, extended instruction workloads, and the Cinebench R15 multi-core test. Its PassMark single-thread score of 3901 beats Intel's 3629 by 7.5%, which indicates stronger per-core execution in certain legacy x86 workloads. The extended instructions result, 22400 versus 20019, gives AMD an 11.9% edge in SIMD-heavy code that leverages newer instruction sets.

The Intel Core i5-14500HX dominates nearly everything else. Its largest victories come in Cinebench R23 multi-core (24234 versus 18316, a 24.4% gap) and Cinebench R23 single-core (3421 versus 2038, a 40.4% gap). The Intel part also leads in floating-point math by 21.6%, prime number finding by 31.5%, physics by 17.4%, and data encryption by 16.7%. Those results point toward a processor that handles sustained compute tasks, particularly rendering and numerical workloads, with more headroom.

The data compression test shows a closer contest: Intel wins by only 5.4% (333851 versus 315906). Random string sorting is nearly tied at 1.6% in Intel's favor. Integer math also lands close, with Intel ahead by 7.4%. These narrow margins suggest that for memory-latency-sensitive or branch-heavy tasks, the two processors are functionally similar, with neither delivering a decisive advantage.

The Cinebench R15 multi-core result is the outlier. AMD wins that test at 2713 versus 2442, an 11.1% margin, even though Intel wins the R23 multi-core test by a wide margin. This reversal indicates that the two Cinebench versions stress different aspects of the CPU, and the AMD part's architecture responds better to the older workload.

Architecture Differences

The two processors come from fundamentally different design philosophies. The AMD Ryzen AI 7 450 uses the Zen 5 architecture under the Gorgon Point codename, belonging to the Ryzen AI 400 generation that mixes Zen 5 and Zen 5c cores. It is built on a 4 nm process at TSMC with a die size of 195 mm². The Intel Core i5-14500HX uses the Raptor Lake architecture under the Raptor Lake-HX codename, part of the Core 14th Gen lineup, fabricated on Intel's 10 nm process with a larger 257 mm² die.

Core counts differ substantially. The AMD part has 8 cores and 16 threads, while the Intel part has 14 cores and 20 threads. This core advantage explains many of Intel's multi-threaded wins, though it does not fully explain the single-core Cinebench gap. Clock speeds also differ: AMD's base clock is 2.00 GHz with a 5.10 GHz boost, while Intel runs at 2.60 GHz base and 4.90 GHz boost. The Intel part starts higher but boosts lower.

Cache layouts diverge. Both use 80 KB of L1 per core. The AMD part has 1 MB of L2 per core and 8 MB of L3, while the Intel part has 2 MB of L2 per core and 24 MB of shared L3. The larger L3 on Intel provides a meaningful advantage for workloads that reuse data across cores.

Thermal design power differs by a wide margin: AMD lists 28 W, Intel lists 55 W. The Intel processor consumes more power budget, which contributes to its higher sustained performance in multi-threaded tests. Memory support also differs: AMD supports DDR5 and LPDDR5X with dual-channel access and 89.6 GB/s of bandwidth, while Intel supports DDR4 and DDR5 with dual-channel access and no recorded bandwidth figure. Both support ECC memory.

PCIe capabilities differ by generation. AMD provides Gen 4 with 16 lanes (CPU only), while Intel provides Gen 5 with 16 lanes (CPU only). Integrated graphics also differ: AMD uses the Radeon 860M, Intel uses UHD Graphics 770. The Intel part has an unlocked multiplier, while the AMD part does not. The AMD socket is FP8, the Intel socket is BGA 1964.

Head-to-Head Benchmarks

The largest single benchmark gap appears in Cinebench R23 single-core, where Intel scores 3421 against AMD's 2038, a 40.4% advantage. This result is striking because the AMD part has a higher boost clock at 5.10 GHz versus 4.90 GHz, yet still trails by a wide margin. The Raptor Lake architecture clearly delivers stronger single-threaded performance in this rendering workload.

Cinebench R23 multi-core also goes to Intel by a large margin: 24234 versus 18316, a 24.4% gap. The combination of more cores, more threads, and larger L3 cache drives this result. The same pattern appears in Cinebench R15 single-core, where Intel wins 344 versus 215, a 37.5% edge.

Floating-point math shows Intel ahead by 21.6% (69442 versus 54447). Prime number finding gives Intel a 31.5% win (130 versus 89). Physics simulation goes to Intel by 17.4% (1911 versus 1578). Data encryption goes to Intel by 16.7% (19502 versus 16247). These results consistently favor the Intel part in numerically intensive or latency-sensitive workloads.

AMD's wins are concentrated in a few specific areas. The PassMark single-thread result gives AMD 3901 versus 3629, a 7.5% margin. Extended instructions give AMD 22400 versus 20019, an 11.9% margin. The Cinebench R15 multi-core win gives AMD 2713 versus 2442, an 11.1% margin. These three wins show that the Zen 5 architecture can outperform Raptor Lake in certain instruction-level and older workload scenarios.

The multi-thread PassMark test gives Intel a 7.6% win (28508 versus 26350). Integer math gives Intel 7.4% (95584 versus 88531). Data compression gives Intel 5.4% (333851 versus 315906). Random string sorting gives Intel just 1.6% (36219 versus 35648). The narrow margins in these tests suggest that for general-purpose integer and memory-bound work, the two processors are closer than the core count difference implies.

Average benchmark scores place the AMD part at 39485 and the Intel part at 35094, giving AMD a higher overall average despite losing most head-to-head tests. The AMD part sits at the 87th percentile versus all CPUs, while the Intel part sits at the 84th percentile. AMD's nearest rivals include the AMD Ryzen 7 PRO 8840HS at a 0.3% lower average score, the AMD Ryzen 7 PRO 8845HS at 0.4% higher, the AMD EPYC 4245P at 0.7% higher, and the AMD Ryzen 7 9800X3D at 0.7% lower. Intel's nearest rivals include the Intel Core i9-12900HX at 0.3% higher, the Intel Core i7-13800H at 0.3% higher, the Intel Core 7 253PTE at 0.4% higher, and the Intel Core i7-12700K at 0.5% lower.

The Verdict

The recorded data indicates that the Intel Core i5-14500HX is the stronger processor for rendering, floating-point math, physics simulation, and encryption. Its wins in Cinebench R23 multi-core and single-core by 24.4% and 40.4% respectively make it the clear choice for content creation workloads that rely on Cinebench-style rendering. The 14-core, 20-thread configuration, combined with 24 MB of shared L3 and a 55 W TDP, delivers consistent multi-threaded performance.

The AMD Ryzen AI 7 450 wins in PassMark single-thread performance, extended instruction workloads, and Cinebench R15 multi-core. Its 7.5% single-thread PassMark lead and 11.9% extended instructions lead suggest that code optimized for newer x86 instruction sets can run faster on this part. The 28 W TDP also indicates a lower power envelope, which matters for thin-and-light laptop designs, though the database does not record battery life or thermal behavior.

For users choosing between these two, the decision rests on workload type. The Intel part delivers higher peak performance in most recorded benchmarks, particularly those that scale with core count and cache size. The AMD part offers competitive single-threaded PassMark performance and a higher average benchmark score, with a substantially lower TDP and a smaller die.

The average benchmark score favors AMD at 39485 versus 35094, a difference of about 12.5%. This metric includes all recorded tests and gives AMD a higher standing despite losing most individual comparisons. The Intel part, however, wins the benchmarks that matter most for heavy compute: Cinebench R23 multi-core, floating-point math, and physics.
