AMD Ryzen 3 5400U vs Intel Core i5-11300H Comparison

The Intel Core i5-11300H and AMD Ryzen 3 5400U are both 4-core, 8-thread mobile processors, but benchmark results show a clear split in their strengths. The AMD Ryzen 3 5400U dominates the Cinebench suite, while the Intel Core i5-11300H takes a decisive lead in Geekbench tests. Overall, the Intel part edges out a higher average benchmark score of 2792 against AMD’s 2765, but the delta between them is marginal in aggregate.

Head-to-Head Benchmarks

The most striking result is the Geekbench split. The Intel Core i5-11300H scores 4907 in Geekbench multicore, beating the AMD Ryzen 3 5400U’s 4473 by 9.7%. The single-core gap is even wider: Intel scores 1589 against AMD’s 1419, a 12% advantage. These are the two largest deltas in the entire comparison, making Geekbench the Intel chip’s strongest territory.

The Cinebench tests tell a different story. Across all six Cinebench runs, the AMD Ryzen 3 5400U wins consistently, but by narrow margins. In Cinebench R23 multicore, AMD scores 9350 versus Intel’s 9127, a 2.4% edge. The single-core R23 result is similar: AMD at 1320 against Intel’s 1288, also a 2.4% difference. This pattern repeats in R20 and R15 — AMD wins multicore by 2.4% in both (3927 vs 3833 in R20; 942 vs 919 in R15) and single-core by 2.3-2.5% (554 vs 540 in R20; 132 vs 129 in R15).

The benchmark data shows AMD winning 6 of the 8 head-to-head tests, but the margins are tight. The largest Cinebench win is just 2.5%, while Intel’s Geekbench wins are 9.7% and 12%. This means the average scores land close: Intel’s 2792 average is only 1% above AMD’s 2765. The Intel chip’s percentile rank of 51 versus AMD’s 50 reflects this near-parity in the broader CPU landscape.

Where Each One Wins

The Intel Core i5-11300H wins in Geekbench, which suggests an advantage in workloads that resemble that benchmark’s mix of integer, floating-point, and memory tasks. The 12% single-core lead and 9.7% multicore lead indicate that Intel’s architecture handles the specific instruction patterns in Geekbench more efficiently. For users running applications that scale similarly to Geekbench’s test suite, the Intel part offers a measurable performance cushion.

The AMD Ryzen 3 5400U wins every Cinebench test, which targets sustained multi-threaded rendering and heavily threaded workloads. The 2.4% multicore advantage in R23, R20, and R15 shows AMD’s Zen 3 cores sustain higher throughput under continuous load. The single-core Cinebench wins, though small at 2.3-2.5%, confirm that AMD’s per-thread performance holds up even in rendering-style tasks. For content creation or CPU-bound rendering, the Ryzen 3 5400U is the safer pick based on these six consistent wins.

The aggregate benchmark score slightly favors Intel, but the win distribution is lopsided. Intel’s two wins are large and decisive; AMD’s six wins are small but consistent. This suggests that the Ryzen 3 5400U delivers more uniform performance across different test types, while the Intel chip’s performance is more variable depending on the workload.

Architecture Differences

The two processors are built on fundamentally different platforms. The Intel Core i5-11300H uses the Tiger Lake-H architecture on a 10 nm process node, fabricated by Intel. The AMD Ryzen 3 5400U uses Zen 3 architecture on a 7 nm process node, fabricated by TSMC. The manufacturing difference is notable: AMD’s 7 nm process is denser, allowing 10,700 million transistors on a 180 mm² die, whereas Intel’s die is 146.1 mm² with no transistor count listed in the data.

Cache configurations differ significantly. The Intel chip has 80 KB of L1 cache per core and 1.25 MB of L2 per core, while the AMD part has 64 KB L1 per core and 512 KB L2 per core. Both share 8 MB of L3 cache, but the per-core L2 advantage for Intel is substantial — 1.25 MB versus 512 KB per core. The L1 cache is also larger on Intel, which can help with latency-sensitive workloads.

Clock speeds are similar at base: both run at 2.60 GHz. The boost clocks differ, with Intel reaching 4.40 GHz versus AMD’s 4.00 GHz. The TDP ratings diverge sharply: Intel is rated at 28 watts, while AMD is rated at 15 watts. This indicates the AMD chip is designed for lower power envelopes, but the benchmark scores show it still competes effectively.

Platform support differs in PCIe generation and lane counts. The Intel chip supports PCIe Gen 4 with 20 lanes (CPU only), while the AMD chip supports PCIe Gen 3 with 8 lanes (CPU only). Both support DDR4 memory in dual-channel configuration with identical 51.2 GB/s memory bandwidth. Neither supports ECC memory. The integrated graphics differ as well: Intel uses Iris XE 80EU, while AMD uses Radeon Vega 6. Both are mobile parts, with Intel on the Intel BGA 1449 socket and AMD on the AMD Socket FP6.

The Verdict

The data supports a clear verdict: choose the Intel Core i5-11300H if Geekbench-style workloads are your priority, and choose the AMD Ryzen 3 5400U for Cinebench-style rendering tasks. The Intel chip’s 12% single-core and 9.7% multicore Geekbench leads are the largest performance gaps in this comparison. If your applications are sensitive to the kind of performance measured by Geekbench, the Intel part provides a tangible advantage.

For sustained multi-threaded rendering, the AMD Ryzen 3 5400U is the winner based on six consecutive Cinebench victories. The 2.4% multicore edge in R23, R20, and R15 is consistent, and the single-core wins in the same suite show AMD’s cores are not just multi-thread specialists. The AMD chip achieves these results with a 15 watt TDP versus Intel’s 28 watts, making it the more power-efficient choice for sustained workloads.

The average benchmark score slightly favors Intel (2792 vs 2765), and Intel’s percentile rank is 51 versus AMD’s 50. However, these aggregate metrics mask the workload-dependent nature of the comparison. The Intel chip’s wins are concentrated in one benchmark family, while AMD’s wins span another. Neither processor is a universal winner. The Intel chip also has a launch MSRP of $309, though no MSRP is listed for the AMD part.
