AMD Ryzen AI 7 PRO 450 vs Intel Core i7-14650HX Comparison

Where Each One Wins

The benchmark data splits these two mobile processors along clear lines. The AMD Ryzen AI 7 PRO 450 takes 3 wins out of 15 head-to-head comparisons, while the Intel Core i7-14650HX claims 12. That raw tally, however, hides the nature of those victories.

The AMD part wins exclusively in single-threaded workloads. It tops the Cinebench R23 single-core test with 2010 against Intel's 1969, a 2.1% edge. It also leads PassMark's single-thread test with 3955 against 3841, a 3% advantage. These are modest margins, but they indicate that Zen 5's per-core efficiency translates into real single-thread performance gains.

The Intel part dominates everywhere else. Its largest wins come in PassMark physics (2202 versus 1337, a 39.3% gap), floating-point math (84999 versus 52971, 37.7% ahead), and data encryption (22917 versus 14925, 34.9% ahead). The Cinebench R15 multicore test shows Intel at 3470.5 versus AMD's 2457, a 29.2% lead. The pattern is consistent: when the workload scales across cores, Intel's 16-core, 24-thread configuration pulls away.

For productivity workloads that use many threads, the Intel processor is the clear choice. For lightly threaded tasks that depend on a single core's efficiency, the AMD processor holds a small but measurable advantage. The database also shows Intel's average benchmark score at 41576 with an 88th percentile ranking among all CPUs, while AMD sits at 37093 with an 85th percentile. Both are strong performers, but Intel occupies a higher overall position.

Architecture Differences

The two processors come from fundamentally different design philosophies. AMD uses a 4 nm TSMC process with Zen 5 architecture under the Gorgon Point codename, part of the Ryzen AI PRO 400 generation that mixes Zen 5 and Zen 5c cores. Intel uses a 10 nm process from its own fabs with Raptor Lake architecture, specifically the Raptor Lake-HX refresh in the Core 14th Gen series.

Core counts diverge sharply. AMD provides 8 cores and 16 threads; Intel provides 16 cores and 24 threads. That 8-core difference explains most of the multicore performance gap. Both share 80 KB of L1 cache per core. L2 differs: AMD allocates 1 MB per core, Intel doubles that to 2 MB per core. L3 is the largest discrepancy, with AMD offering 8 MB total versus Intel's 30 MB shared.

Clock speeds are close. AMD starts at 2.00 GHz base and boosts to 5.10 GHz; Intel starts at 2.20 GHz and boosts to 5.20 GHz. The thermal envelopes differ substantially, with AMD rated at 28 W TDP and Intel at 55 W. That 27 W difference reflects Intel's higher core count and the power needed to feed it.

Memory support shows different strategies. AMD supports DDR5 and LPDDR5X across a dual-channel bus with 89.6 GB/s bandwidth. Intel supports DDR4 and DDR5 on a dual-channel bus, with no bandwidth figure recorded. Both support ECC memory. PCIe generations differ: AMD uses Gen 4 with 16 CPU lanes, Intel uses Gen 5 with 16 CPU lanes.

Integrated graphics also differ. AMD pairs the CPU with a Radeon 860M; Intel uses UHD Graphics 710. The AMD die measures 195 mm² versus Intel's 257 mm². Intel's multiplier is unlocked; AMD's is not. Intel launched in January 2024, while AMD's release date is recorded as January 2026. Both are listed as Active in production status and target the mobile market segment.

Head-to-Head Benchmarks

The Cinebench R15 multicore test shows Intel's largest single benchmark win. Intel scores 3470.5 against AMD's 2457, a 29.2% advantage. The R15 single-core test follows the same direction but with a smaller margin: Intel at 285.5 versus AMD at 220, a 22.9% lead. Cinebench R23 multicore shows Intel at 20454 against 16054, a 21.5% gap.

The single-core results flip in R23. AMD edges Intel 2010 to 1969, a 2.1% win. PassMark's single-thread test repeats that outcome with AMD at 3955 and Intel at 3841, a 3% margin. These are the only two tests where AMD wins, and both are single-threaded.

PassMark's math workloads show Intel's strongest areas. Floating-point math: Intel 84999, AMD 52971, a 37.7% gap. Integer math: Intel 116661, AMD 86227, 26.1% ahead. Prime number finding: Intel 152, AMD 84, a 44.7% gap, the largest delta in the entire dataset. Physics: Intel 2202, AMD 1337, 39.3% ahead. Extended instructions: Intel 24150, AMD 20778, 14% ahead.

Data workloads follow the same pattern. Data compression: Intel 398418, AMD 294298, 26.1% ahead. Data encryption: Intel 22917, AMD 14925, 34.9% ahead. Random string sorting: Intel 43035, AMD 32344, 24.8% ahead. PassMark multithread: Intel 33495, AMD 24779, 26% ahead.

The deltas range from Intel's 44.7% edge in prime number finding to AMD's 3% edge in single-threaded PassMark. The data indicates that Intel's multicore advantage is broad and consistent, while AMD's single-thread advantage is narrow but repeatable across two independent test suites.

The Verdict

The data supports a straightforward split. The Intel Core i7-14650HX is the stronger processor for multithreaded workloads. Its 16 cores and 24 threads produce leads between 14% and 44.7% across every multicore test in the database. The 88th percentile ranking and 41576 average score confirm its position above the AMD part in overall performance.

The AMD Ryzen AI 7 PRO 450 wins only where single-thread efficiency matters most. Its 2.1% Cinebench R23 single-core win and 3% PassMark single-thread win show a real but narrow advantage. The 85th percentile ranking and 37093 average score place it slightly behind, though the 28 W TDP against Intel's 55 W suggests the AMD part achieves its results with a much lower power envelope.

For workloads that use many cores, such as rendering, physics simulation, encryption, or compression, the Intel processor is the recorded leader. For single-threaded tasks where per-core efficiency is the priority, the AMD processor holds the edge. The choice between them depends on which workload profile matters more: Intel for throughput, AMD for single-core responsiveness at lower power.
