AMD Ryzen AI 7 445 vs Intel Core i5-14450HX Comparison

The AMD Ryzen AI 7 445 and Intel Core i5-14450HX represent two distinct philosophies in mobile computing. The recorded data shows a decisive performance gap, with the Intel part winning all 15 head-to-head benchmark comparisons. The analysis below details the measured deltas, architectural reasons for the divergence, and the practical implications for system designers and users.

Head-to-Head Benchmarks

The most pronounced difference appears in multi-threaded workloads. In Cinebench R23 multi-core, the Intel Core i5-14450HX scores 20,108 compared to the AMD Ryzen AI 7 445’s 10,590, a delta of -47.3% for AMD. This near-doubling of performance is the single largest gap in the dataset. Cinebench R15 multi-core shows a smaller but still significant gap: Intel leads 2,026 to 1,723, a -15% delta.

Single-core performance also favors Intel, though by a narrower margin. Cinebench R23 single-core gives Intel a 2,838 score against AMD’s 1,806, a -36.4% delta. Cinebench R15 single-core shows Intel at 285 versus AMD’s 254, a -10.9% delta. The PassMark single-thread test narrows the gap further to -1.4%, with Intel scoring 3,643 and AMD scoring 3,591. This indicates that while Intel has a clear architectural efficiency edge in lightly-threaded tasks, the per-core clock advantage is not overwhelming.

In PassMark’s synthetic workloads, Intel maintains a consistent lead across the board. Integer math shows Intel at 78,330 against AMD’s 58,332, a -25.5% delta. Floating-point math follows suit: 58,037 for Intel versus 39,362 for AMD, a -32.2% delta. Data encryption delivers a -32.5% delta (15,574 vs. 10,519), while data compression shows a -22.5% delta (278,538 vs. 215,812). The extended instructions test is the closest of the PassMark suite, with Intel leading 17,207 to 15,826, a -8% delta.

Memory-sensitive and physics-based tests reinforce the trend. PassMark physics scores 1,475 for Intel and 976 for AMD, a -33.8% delta. Random string sorting shows Intel at 29,565 and AMD at 23,488, a -20.6% delta. Prime number finding yields the second-largest percentage gap: Intel scores 98 versus AMD’s 56, a -42.9% delta. PassMark multi-thread performance lands at 23,680 for Intel and 18,115 for AMD, a -23.5% delta.

The overall average benchmark score confirms the hierarchy: Intel’s 32,040 average versus AMD’s 26,936. Intel’s percentile rank among all CPUs is 82, while AMD sits at 79. In the nearest rivals comparison, AMD’s average score places it within 0.6% of the Intel Core i9-9900K and AMD Ryzen 7 5700G, while Intel’s score is nearly identical to the Intel Core i7-13705H and Intel Core i5-14400. The data shows no workload category where the AMD Ryzen AI 7 445 closes the gap.

Architecture Differences

The two processors diverge fundamentally in core configuration and fabrication. The AMD Ryzen AI 7 445 uses a Zen 5 architecture on a 4 nm TSMC process, codenamed Gorgon Point, part of the Ryzen AI 400 generation which mixes Zen 5 and Zen 5c cores. It provides 6 cores and 12 threads. The Intel Core i5-14450HX is built on Raptor Lake architecture, using a 10 nm Intel process with a die size of 257 mm². It provides 10 cores and 16 threads. This core count difference, 10 versus 6, is the primary driver of the multi-threaded benchmark deltas.

Cache hierarchy also differs. Both parts share 80 KB of L1 per core. AMD provides 1 MB of L2 per core and 4 MB of L3 total. Intel provides 2 MB of L2 per core and 20 MB of shared L3. The larger L2 and L3 capacities on Intel likely contribute to its advantages in data compression and random string sorting, where cache residency matters.

Clock speeds favor Intel as well. Intel’s base clock is 2.40 GHz with a boost of 4.80 GHz. AMD’s base is 2.00 GHz with a boost of 4.60 GHz. The higher boost clock on Intel aligns with its single-core Cinebench wins, though the PassMark single-thread delta of only -1.4% suggests the Zen 5 core has strong instructions-per-clock efficiency that partially compensates for the lower frequency.

Power and platform characteristics differ substantially. AMD’s TDP is 28 W, while Intel’s is 55 W. This is a major thermal design divergence, suggesting Intel’s performance comes with a much higher power budget. AMD uses socket FP8, Intel uses BGA 1964. Memory support differs: AMD supports DDR5 and LPDDR5X with a dual-channel bus and 89.6 GB/s bandwidth, while Intel supports DDR4 and DDR5 with a dual-channel bus but no recorded bandwidth figure in the database. Both support ECC memory.

PCIe connectivity also differentiates them. AMD provides Gen 4 with 14 CPU lanes, while Intel provides Gen 5 with 16 CPU lanes. Integrated graphics differ: AMD uses Radeon 840M, Intel uses UHD Graphics 710. Intel’s multiplier is unlocked, AMD’s is not. Intel’s release date is January 2024, AMD’s is January 2026, making the AMD part the newer design despite its lower performance in these tests. Intel’s process node is 10 nm versus AMD’s 4 nm, but the database shows that the larger, older Intel process still delivers higher benchmark scores.

The Verdict

The benchmark data is unambiguous. The Intel Core i5-14450HX wins every recorded comparison, with deltas ranging from -1.4% in single-threaded PassMark to -47.3% in Cinebench R23 multi-core. The average benchmark score of 32,040 for Intel versus 26,936 for AMD represents a 19% advantage for Intel in aggregate performance. Intel’s higher core count, larger cache, and higher clock speeds provide a comprehensive lead across integer math, floating-point math, encryption, compression, physics, and rendering workloads.

The AMD Ryzen AI 7 445, however, operates at a 28 W TDP compared to Intel’s 55 W. The database does not record thermal or power efficiency metrics, so any claim about performance per watt cannot be substantiated from the available data. What the data does show is that AMD’s 4 nm process and newer architecture do not translate into benchmark superiority in these tests. The AMD part’s nearest rivals include the Intel Core i7-1370P and AMD Ryzen 5 7545U, indicating it competes in a lower performance tier.

For users prioritizing raw compute throughput, the Intel Core i5-14450HX is the clear choice based on recorded data. For users constrained by power budgets or thermal limits, the AMD part may be viable, but the database provides no measurements to confirm that advantage. The verdict from the numbers alone: Intel delivers more performance in every measured category, often by substantial margins, while AMD offers a newer process node and lower TDP without a corresponding benchmark gain.

Where Each One Wins

The Intel Core i5-14450HX wins every recorded workload, but the margin of victory varies by category. Its largest wins are in multi-core rendering and prime number calculations, where the extra cores and threads provide a massive advantage. Cinebench R23 multi-core shows a 47.3% lead, and PassMark find prime numbers shows a 42.9% lead. These are workloads that scale with core count and cache size.

The Intel part also dominates in encryption and physics. Data encryption shows a 32.5% lead, and physics shows a 33.8% lead. Floating-point math follows with a 32.2% lead. These results indicate that Intel’s architecture handles both integer and floating-point heavy tasks effectively.

In contrast, the AMD Ryzen AI 7 445’s closest results are in single-threaded PassMark and extended instructions. The -1.4% delta in single-thread and -8% delta in extended instructions suggest that Zen 5 has competitive per-core efficiency. For workloads that are not multi-core reliant, the AMD part is much closer to Intel, but it still loses.

The Intel Core i5-14450HX is the stronger choice for any compute-intensive application where power consumption is not the primary constraint. The AMD Ryzen AI 7 445 may be suitable for power-sensitive designs, but the database does not record efficiency metrics to validate that trade-off. The measured performance hierarchy is consistent: Intel wins all 15 comparisons, with the largest gaps in multi-core and math-intensive tasks, and the smallest gaps in single-threaded efficiency tests.
