AMD Ryzen 5 7540U vs Intel Core i7-13620H Comparison

Head-to-Head Benchmarks

The benchmark data paints a decisively one-sided picture. The Intel Core i7-13620H wins 14 of the 15 recorded head-to-head comparisons, with the AMD Ryzen 5 7540U taking a single, narrow victory. The margin of that AMD win is razor-thin: in Cinebench R15 single-core, the Ryzen scores 264 against Intel's 263, a 0.4% edge that is effectively a tie in real-world terms.

The multi-core results show the largest gaps. In Cinebench R23 multi-core, Intel posts 15176 points versus AMD's 10383, a 31.6% deficit for the Ryzen. The Cinebench R15 multi-core test tells a similar story: Intel scores 2281 against 1676, a 26.5% advantage. These are substantial differences that reflect the Intel part's greater core and thread count.

PassMark's physics workload delivers the single biggest swing. Intel scores 1671 against AMD's 964, a 42.3% lead. Floating-point math also heavily favors Intel, with 59762 versus 36077, a 39.6% gap. Prime number finding shows a 33.3% Intel advantage (99 versus 66), while integer math lands at 25.7% (80948 versus 60152).

The Intel chip also wins the efficiency-adjacent workloads, though by smaller margins. Data compression favors Intel by 24.8% (281335 versus 211581), data encryption by 19.3% (15568 versus 12563), and random string sorting by 15.8% (29395 versus 24760). Extended instructions are 12.6% better on Intel (17513 versus 15307). The multithread PassMark aggregate shows Intel ahead by 23.2% (24192 versus 18576).

Single-thread performance is far closer. In Cinebench R23 single-core, Intel leads by 7.3% (1833 versus 1699). PassMark single-thread shows Intel at 3589 versus AMD's 3544, a 1.3% margin that falls within normal run-to-run variance. The overall database averages reflect this proximity: Intel's average benchmark score is 24911 against AMD's 24188, a difference of roughly 3%. The percentile rankings are similarly close, with Intel at the 77th percentile and AMD at the 76th percentile of all CPUs.

Architecture Differences

The two processors come from fundamentally different design philosophies. AMD's Ryzen 5 7540U uses the Zen 4 architecture under the Phoenix codename, built on a 4 nm process at TSMC. Intel's Core i7-13620H uses Raptor Lake, specifically the Raptor Lake-H refresh, fabricated on a 10 nm process at Intel's own foundries. The process node difference is significant: the AMD part's 4 nm TSMC process is denser and more power-efficient on paper, while Intel's 10 nm process node designation reflects a different naming convention and manufacturing approach.

Core configuration differs sharply. The Ryzen 7540U has 6 cores and 12 threads, with a base clock of 3.20 GHz and boost up to 4.90 GHz. The Core i7-13620Hhas 10 cores and 16 threads, carrying a base clock of 4.90 GHz on its boost clock. The Intel chip has a 45 W TDP rating versus the AMD part's 28 W TDP. Cache layouts also diverge: per-core L1 is 64 KB on AMD versus 80 KB on Intel, and per-core L2 is 64 KB on AMD versus 2 MB on Intel. The L3 cache totals 16 MB shared for the Ryzen 5 7540U versus 24 MB shared for the Core i7-13620H.

Memory support differs as well. The Ryzen has 7540U supports DDR5 memory, with a memory bus rated at 89.0 GHz. The Core i7-13620H supports DDR4 and DDR5 memory. The Core i7-13620H has a 45 W TDP rating, while both parts are listed as mobile processors. The Ryzen 5 7540U has a 28 W TDP rating. The Core i7-13620H is a Core i7-13620H with an Intel BGA 1744 socket, whereas the 7540U uses AMD Socket FP7.0 GHz for DDR5 memory. The Ryzen 5 7540U has a 28 W TDP rating, while the Core i7-13620H is a 45 W part. The Core i7-13620H has a 2.5 GHz base clock. The Ryzen 5 7540U has a 3.2 GHz base clock. The Core i7-13620H supports dual-channel memory, as does the 7540U.

Where Each One Wins

The Intel Core i7-13620H is the clear choice for multi-threaded workloads. Its 10 cores and 16 threads give it a decisive edge in rendering, physics simulation, and heavy compute tasks. The Cinebench R23 multi-core result of 15176 versus 10383 is a 31.6% advantage, and the PassMark physics score shows a 42.3% gap. Users who regularly run video encoding, 3D rendering, or scientific calculations will see the largest real-world gains from the Intel part. The data compression (24.8%), encryption (19.3%), and integer math (25.7%) wins also point to productivity and server-like workloads favoring Intel.

The AMD Ryzen 5 7540U wins exactly one benchmark, Cinebench R15 single-core, by 0.4%. That is not a meaningful basis for a purchase decision. However, the AMD chip does have structural advantages worth noting. Its 28 W TDP versus Intel's 45 W TDP suggests lower power draw, and its 4 nm TSMC process node is significantly more advanced than Intel's 10 nm node. The AMD part also supports ECC memory, which Intel does not, and its PCIe Gen 4 implementation with 20 lanes differs from Intel's Gen 5 with 8 lanes. For systems where ECC memory support or lower power consumption is critical, the Ryzen 5 7540U has a role despite its benchmark deficit.

For single-thread responsiveness, the two are nearly indistinguishable. The Cinebench R23 single-core gap is 7.3% in Intel's favor, and PassMark single-thread is 1.3%. Everyday tasks like web browsing, office work, and light application use will not expose a meaningful difference. The Intel part's 45 W TDP and 10-core design make it the stronger performer in sustained multi-core workloads, while the AMD part's 28 W TDP and smaller process node position it as the more thermally efficient option for thin-and-light mobile designs. The benchmark data is unambiguous: if raw performance is the priority, the Core i7-13620H wins nearly every measurable workload.
