A: Yes, both the Intel Core i5-11400H and the AMD Ryzen 3 7440U have an active production status. The Intel chip was released on 2021-05-10, while the AMD chip launched later on 2023-05-02.

Architecture Differences

The Intel Core i5-11400H is built on the Tiger Lake-H architecture, which uses Intel's 10 nm process node and is fabricated by Intel itself. The die size measures 190 mm². This is a 6-core, 12-thread design with a base clock of 2.20 GHz and a boost clock of 4.50 GHz. The chip operates at a 35 W TDP and uses the Intel BGA 1787 socket.

The AMD Ryzen 3 7440U uses the Zen 4 architecture under the codename Phoenix2, fabricated by TSMC on a 4 nm process node. The die is smaller at 137 mm², and the chip integrates 20,900 million transistors. This is a 4-core, 8-thread processor with a base clock of 3.00 GHz and a boost clock of 4.70 GHz. It runs at a lower 28 W TDP and uses the AMD Socket FP7.

Cache configurations differ substantially. Intel provides 80 KB of L1 cache per core and 1.25 MB of L2 per core, with a shared 12 MB L3 cache. AMD provides 64 KB of L1 per core and 1 MB of L2 per core, with a shared 8 MB L3 cache. The Intel chip has more total cache at every level, which helps in workloads that repeatedly access working sets.

Memory support diverges sharply. The Intel chip uses DDR4 with 51.2 GB/s of bandwidth, while the AMD chip supports DDR5 and reaches 89.6 GB/s. That is a 75% bandwidth advantage for AMD, yet it does not translate into benchmark wins in most tests. The AMD processor also supports ECC memory, which the Intel chip does not.

PCIe connectivity differs as well. Intel provides Gen 4 with 20 lanes from the CPU, while AMD provides Gen 4 with 14 lanes. Integrated graphics also differ: Intel uses UHD Graphics, while AMD uses Radeon 740M. Both chips are mobile parts with locked multipliers, and neither offers an unlocked overclocking path.

The Verdict

The data points to a clear winner for overall compute performance. The Intel Core i5-11400H wins 17 of the 19 head-to-head benchmark comparisons, including every Cinebench test, every multi-core test, and most single-thread tests. Its average benchmark score of 15749 edges out the AMD Ryzen 3 7440U's 15682 by 0.4%, and both sit at the 69th percentile of all CPUs.

However, the AMD chip is not without merit. It wins decisively in Geekbench single-core by 21.7%, suggesting better per-thread performance in that specific workload. It also wins PassMark physics by 27.8%, indicating superior performance in physics simulation tasks. The AMD chip also supports DDR5 memory with 89.6 GB/s bandwidth and ECC memory, which may matter for certain professional or reliability-focused use cases.

For users who prioritize multi-threaded compute, rendering, or general productivity, the Intel Core i5-11400H is the stronger choice based on the benchmark data. It leads by 16.5% across all Cinebench multi-core tests and by 45% in PassMark integer math. For users who need single-core Geekbench performance or physics simulation, the AMD Ryzen 3 7440U offers a specific advantage, though it trails in most other categories.

Head-to-Head Benchmarks

The Intel Core i5-11400H dominates the Cinebench suite. In Cinebench R15 multi-core, Intel scores 1296 against AMD's 1112, a 16.5% lead. The single-core R15 test shows a 16.7% advantage (182 vs 156). Cinebench R20 multi-core continues the trend: Intel at 5400, AMD at 4637, again 16.5% ahead. R20 single-core follows the same pattern with Intel at 762 and AMD at 654, a 16.5% difference. Cinebench R23 multi-core has Intel at 12859 and AMD at 11042, while R23 single-core has Intel at 1815 and AMD at 1558 — both showing the same 16.5% gap.

Geekbench results split the two processors. In Geekbench multi-core, Intel wins 6396 to 5806, a 10.2% margin. But in Geekbench single-core, AMD turns the tables with a 2003 score versus Intel's 1569, giving AMD a 21.7% advantage. This is AMD's largest single-core win anywhere in the benchmark set.

PassMark tests reveal where Intel's extra cores pay off most heavily. The largest margin comes in floating-point math, where Intel scores 32060 against AMD's 20291 — a 58% advantage. Integer math shows Intel at 53286 and AMD at 36758, a 45% lead. Extended instructions favor Intel by 25.3% (12971 vs 10356). Data compression shows Intel at 190855 and AMD at 153689, a 24.2% edge. Finding prime numbers goes Intel's way by 17.5% (47 vs 40). PassMark multi-thread has Intel at 15346 and AMD at 12991, an 18.1% lead. Single-thread PassMark gives Intel 2975 versus AMD's 2614, a 13.8% margin. Random string sorting is closer, with Intel at 22512 and AMD at 21479, just 4.8% apart. Data encryption is the tightest race: Intel at 9309, AMD at 9215, only 1% separating them.

AMD's second win comes in PassMark physics, where it scores 939 against Intel's 678, a 27.8% advantage. This is the only other test AMD wins, and it is a substantial margin that suggests a specific strength in physics workloads.

Where Each One Wins

The Intel Core i5-11400H is the clear choice for multi-threaded and compute-heavy tasks. Every Cinebench multi-core test goes to Intel by 16.5%, and the gap grows to 45% in integer math and 58% in floating-point math. Data compression and extended instruction workloads also favor Intel by roughly 25%. Users running rendering, code compilation, data processing, or any workload that scales across cores will see tangible benefits from Intel's 6-core, 12-thread configuration.

The Intel chip also wins most single-thread tests. PassMark single-thread shows Intel ahead by 13.8%, and Cinebench single-core tests all favor Intel by about 16.5%. Only Geekbench single-core breaks this pattern, where AMD leads by 21.7%. For users who rely on Geekbench as their primary single-thread metric, the AMD chip offers a compelling advantage, but the broader set of single-thread tests favors Intel.

The AMD Ryzen 3 7440U wins in two specific areas. First, PassMark physics shows a 27.8% advantage, which could matter for physics simulation in certain applications or game engines. Second, Geekbench single-core shows a 21.7% lead, which may translate to snappier responsiveness in lightly threaded applications that are well-represented by that benchmark. Additionally, the AMD chip supports DDR5 memory with 89.6 GB/s bandwidth and ECC memory, offering architectural benefits that do not show up in raw compute scores but may matter for memory-intensive workloads or environments requiring error correction.

In terms of overall average benchmark score, the Intel chip leads by just 0.4% (15749 vs 15682), and both processors sit at the 69th percentile of all CPUs. This means that while Intel wins the vast majority of individual tests, the aggregate performance is remarkably close, and the choice between them depends heavily on the specific workload and whether the user values Intel's multi-threaded dominance or AMD's single-thread Geekbench and physics advantages.
