AMD Ryzen 3 5425U vs Intel Core i7-11375H Comparison

Head-to-Head Benchmarks

The recorded data presents a decisive picture in the direct comparisons between the Intel Core i7-11375H and the AMD Ryzen 3 5425U. Across all four shared benchmark tests, the Intel processor secures the win, with a head-to-head record of 4 wins to 0.

The most significant difference emerges in multi-threaded workloads. In Cinebench R23 multi-core, the Intel Core i7-11375H scores 9775, while the AMD Ryzen 3 5425U records 5954.5. This translates to a 64.2% advantage for the Intel part. This is a substantial gap, suggesting that the Intel chip sustains higher throughput under heavy parallel loads. The Geekbench multi-core test reinforces this trend, with Intel scoring 5383 against AMD's 3880, a 38.7% lead.

While the multi-core wins are commanding, the single-core results show a different dynamic. In Cinebench R23 single-core, the Intel i7-11375H scores 1380, only 3.6% ahead of the Ryzen 3's 1332. This is a much closer margin, indicating that the Zen 3 architecture in the AMD chip is highly competitive in lightly-threaded tasks. However, the Geekbench single-core test tells a different story, with Intel scoring 1800 versus AMD's 1328, a 35.5% lead for Intel. The discrepancy between these two single-core tests is notable; the Cinebench result suggests near-parity, while Geekbench indicates a strong Intel advantage. The data implies that the Intel chip has a significant peak-frequency advantage that certain workloads can exploit, whereas others may be more sensitive to architectural efficiency.

Looking at the broader context, the average benchmark score for the AMD Ryzen 3 5425U is 3124, which is actually higher than the Intel Core i7-11375H's average of 3018. This is because the AMD dataset includes fewer high-end tests, skewing its average. However, this does not change the fact that in every direct head-to-head test, the Intel part is faster. The Intel chip's nearest rivals include the AMD Ryzen 5 5600U, which has an average score of 3053, placing the i7-11375H just 1.1% behind that part. The Ryzen 3 5425U sits alongside the Intel Core i3-13100TE, with its average of 3111 putting it 0.4% ahead of the AMD chip.

Architecture Differences

The two processors come from fundamentally different design philosophies. The Intel Core i7-11375H is built on the Tiger Lake-H architecture, using a 10 nm process node fabricated by Intel. The AMD Ryzen 3 5425U, codenamed Barcelo, uses the Zen 3 architecture on a 7 nm node from TSMC. This process advantage for AMD allows for a smaller transistor size, but the Intel chip has a smaller die size at 146.1 mm² compared to the AMD's 180 mm². The AMD processor integrates a significantly higher transistor count, with 10,700 million, though no figure is recorded for the Intel chip.

Both processors feature 4 cores and 8 threads, making them comparable in logical core count. However, the cache hierarchies differ. The Intel chip has a larger L3 cache at 12 MB shared, while the AMD chip has 8 MB shared. Per-core, Intel's L1 cache is 80 KB and its L2 is 1.25 MB per core, whereas AMD's L1 is 64 KB per core and L2 is 512 KB per core. This larger cache allocation on the Intel side may contribute to its higher single-core Geekbench score.

Clock speeds are another differentiator. The Intel i7-11375H has a base clock of 3.00 GHz and a boost clock of 5.00 GHz. The AMD Ryzen 3 5425U starts at 2.70 GHz and boosts to 4.10 GHz. The higher boost clock on the Intel chip likely explains its peak performance in burst workloads. The thermal design power (TDP) also differs, with Intel rated at 28 watts and AMD at 15 watts, indicating that the Intel processor is designed for a more performance-oriented power envelope.

The platform specifications also diverge. The Intel chip uses the Intel BGA 1449 socket, while AMD uses the AMD Socket FP6. Intel supports PCIe Gen 4 with 20 lanes from the CPU, while AMD is limited to PCIe Gen 3 with 16 lanes. Both support dual-channel DDR4 memory with a bandwidth of 51.2 GB/s. Interestingly, the AMD chip supports ECC memory, while the Intel chip does not. The integrated graphics differ as well, with Intel featuring Iris XE 96EU and AMD featuring Radeon Vega 6.

The release dates are also distinct, with Intel launching on 2021-01-10 and AMD on 2022-01-05. The Intel part has a recorded launch MSRP of $482, while no launch price is listed for the AMD chip.

The Verdict

The data clearly points to the Intel Core i7-11375H as the superior performer in every measured benchmark. With a 64.2% lead in Cinebench R23 multi-core and a 35.5% lead in Geekbench single-core, the Intel chip dominates the comparison. The only close contest is Cinebench R23 single-core, where Intel's 3.6% lead indicates that the AMD architecture is not far behind in that specific workload. However, the broader pattern of results suggests that the Intel chip's higher boost clock and larger cache provide a tangible performance advantage across the board.

The AMD Ryzen 3 5425U does have its merits. Its 15-watt TDP is significantly lower than Intel's 28 watts, implying better power efficiency for thin-and-light laptops. It also supports ECC memory and has a newer release date. But for pure compute performance, the Intel Core i7-11375H is the clear winner. The AMD chip's average benchmark score is higher only because its dataset lacks the heavy multi-core tests that drag down Intel's average; in direct comparisons, it loses every round.

Where Each One Wins

The Intel Core i7-11375H wins decisively in raw computational performance. It is the clear choice for applications that demand high multi-threaded throughput, as evidenced by its 64.2% lead in Cinebench R23 multi-core. It also excels in bursty, single-threaded tasks where its 5.00 GHz boost clock can be leveraged, as shown by its 35.5% lead in Geekbench single-core. Users running heavy productivity workloads, content creation, or compilation tasks would benefit from the Intel chip's performance headroom.

The AMD Ryzen 3 5425U, while losing all benchmark comparisons, still has a distinct advantage in power efficiency. With a 15-watt TDP, it draws significantly less power than Intel's 28-watt design. This makes it a better fit for fanless or ultra-portable laptops where battery life and thermal management are a priority. Its support for ECC memory is also a unique feature that could be relevant in specific professional use cases. The AMD chip's closer margin in Cinebench R23 single-core, at just 3.6% behind Intel, shows that Zen 3 is architecturally efficient in certain light workloads. The data suggests that the AMD chip is a sensible pick for users who prioritize efficiency and quiet operation over maximum performance.
