AMD Ryzen 3 PRO 5450U vs Intel Core i5-11320H Comparison

The Intel Core i5-11320H and AMD Ryzen 3 PRO 5450U are both 4-core, 8-thread mobile processors, but they represent different architectural approaches. The database records eight head-to-head benchmarks, and the results are split: the AMD part wins all six Cinebench tests, while the Intel part wins both Geekbench tests. This analysis examines the benchmark data, the use-case implications, and the architectural and specification differences between the two.

Head-to-Head Benchmarks

Across the eight recorded benchmarks, the AMD Ryzen 3 PRO 5450U takes six wins, all in the Cinebench suite. The margins are consistent: 2.5% in Cinebench R15 multi-core (947 vs 923), 2.3% in R15 single-core (133 vs 130), 2.6% in R20 multi-core (3949 vs 3846), 2.5% in R20 single-core (557 vs 543), 2.6% in R23 multi-core (9403 vs 9158), and 2.6% in R23 single-core (1327 vs 1293). These are narrow but uniform leads, indicating a small but reliable advantage in rendering workloads.

The Intel Core i5-11320H counters with two wins in Geekbench. The multi-core result is a decisive 17.4% lead (5620 vs 4788), while the single-core result is a more modest 4.3% lead (1592 vs 1527). The multi-core Geekbench margin is the largest of any test in this comparison, making it the standout win for Intel. The data shows that the AMD part is consistently ahead in Cinebench, but the Intel part has a much larger advantage in Geekbench multi-core, which suggests that the two architectures respond very differently to the workload characteristics.

Where Each One Wins

Based on the benchmark distribution, the AMD Ryzen 3 PRO 5450U is the better choice for workloads that resemble Cinebench, such as 3D rendering, ray tracing, and other CPU-intensive creative tasks. The consistent 2.3% to 2.6% advantage across all Cinebench versions suggests that the Zen 3 architecture handles these sustained multi-threaded and single-threaded rendering tasks slightly better than Tiger Lake-H. For users who prioritize rendering performance, the AMD part is the clear winner in this comparison.

Conversely, the Intel Core i5-11320H dominates Geekbench, which simulates a broader range of everyday tasks including encryption, image processing, and machine learning. The 17.4% multi-core lead is substantial, and the 4.3% single-core lead also favors Intel. For general productivity, web browsing, and office applications, the Intel part is likely to deliver better performance. The Geekbench multi-core result is particularly striking, as it shows a large gap that is not present in any Cinebench test.

It is notably both processors have the same core and thread count, so the differences are purely architectural. The AMD part has a higher base clock (2.60 vs 2.50) but a lower boost clock (4.00 vs 4.50). The recorded data shows that the AMD part wins in Cinebench despite the lower boost, while the Intel part wins in Geekbench despite the lower base clock. This suggests that the two architectures have different strengths: AMD excels in sustained rendering workloads, while Intel excels in general-purpose multi-threaded tasks.

Architecture Differences

Under the hood, the two processors are built on different process nodes and foundries. The Intel Core i5-11320H uses Intel's 10 nm process and is fabricated by Intel itself, while the AMD Ryzen 3 PRO 5450U uses TSMC's 7 nm process. The AMD part integrates 10,700 million transistors on a 180 mm² die, whereas the Intel die size is 146.1 mm² (transistor count is not specified in the database). The smaller process node on the AMD side may contribute to its lower TDP, but the benchmark results do not show a direct correlation.

The cache hierarchy differs as well. Intel provides 80 KB of L1 and 1.25 MB of L2 per core, while AMD provides 64 KB of L1 and 512 KB of L2 per core. Both share 8 MB of L3. The larger per-core caches on the Intel side may help in certain latency-sensitive workloads, but the benchmark results do not show a consistent advantage. The L3 cache is identical, so the difference lies in the lower levels.

PCIe support is another differentiator: Intel offers Gen 4 with 20 lanes (CPU only), while AMD offers Gen 3 with 8 lanes. This gives the Intel part more bandwidth for external devices such as GPUs and NVMe drives. Integrated graphics also differ: Intel uses Iris XE with 96 execution units, while AMD uses Radeon Vega 6. The TDP is also different: Intel is rated at 28 W, AMD at 15 W, which affects thermal and power characteristics in mobile designs. The sockets are incompatible: Intel uses BGA 1449, AMD uses FP6. The release dates are also different, with AMD launching on 2021-03-15 and Intel on 2021-06-20.
