AMD Ryzen 7 7735HS vs Intel Core i7-13620H Comparison

The AMD Ryzen 7 7735HS and Intel Core i7-13620H are both mobile processors aimed at high-performance laptops, but benchmark results show they are not interchangeable. The Intel chip wins the majority of head-to-head tests, taking 15 of 21 comparisons, while the AMD chip secures 6 wins. However, the data reveals a clear performance split: Intel dominates in raw speed and physics, while AMD takes the lead in several specialized computing tasks.

Head-to-Head Benchmarks

The Intel Core i7-13620H’s most decisive victories come in single-thread and physics workloads. In passmark_physics, Intel scores 1671 against AMD’s 1073, a 35.8% advantage. The gap is even larger in passmark_find_prime_numbers, where Intel scores 99 versus AMD’s 59, a 40.4% delta that suggests a major difference in integer-heavy algorithmic work. These results indicate that Intel’s architecture handles latency-sensitive and branch-heavy instructions far more efficiently.

The multi-core picture is more nuanced. In Cinebench R23 multi-core, Intel scores 15176 versus AMD’s 13106, a 13.6% lead. The 3DMark 16-thread test shows a smaller but still Intel-favorable gap: 7056 versus 6870, a 2.6% delta. Yet AMD wins the 3DMark 8-thread test outright, scoring 5697 against Intel’s 5443, a 4.7% margin. This suggests AMD’s eight full cores are better optimized for moderate thread counts, while Intel’s hybrid layout scales better when all 16 threads are saturated.

AMD’s biggest single win is in passmark_data_encryption, where it scores 18237 versus Intel’s 15568, a 17.1% advantage. The Ryzen chip also leads in passmark_extended_instructions by 14.5% (20050 versus 17513), and in passmark_integer_math by 5.4% (85309 versus 80948). These results point to AMD’s strengths in security-related and integer-heavy workloads. In data compression, AMD leads by 4.2% (293278 versus 281335), and in random string sorting by 3.4% (30388 versus 29395).

Intel sweeps the remaining single-thread metrics. In 3DMark single-thread, Intel scores 1008 versus 912, a 9.5% lead. Cinebench R23 single-core shows Intel ahead by 15.7% (1833 versus 1546), and passmark_single_thread gives Intel 3589 versus 3296, an 8.2% delta. Intel also wins floating-point math by 19.9% (59762 versus 47865), and the 2-thread and 4-thread 3DMark tests by 9.7% and 6.6% respectively.

Architecture Differences

The two chips use fundamentally different internal designs. AMD’s Ryzen 7 7735HS is built on the Zen 3+ architecture, codenamed Rembrandt-R, manufactured on a 6 nm process at TSMC. Intel’s Core i7-13620H uses Raptor Lake architecture, codenamed Raptor Lake-H, on Intel’s 10 nm process. This process difference is significant: the smaller node typically allows for better power efficiency, though the benchmark data shows Intel’s larger node still delivers higher peak performance in most tests.

Core configurations differ considerably. The AMD chip has 8 cores and 16 threads, all using the same architecture. Intel has 10 cores and 16 threads, implying a hybrid design with performance and efficiency cores, though the exact mix is not specified in the data. Intel’s L2 cache is larger per core at 2 MB versus AMD’s 512 KB, and Intel’s shared L3 cache is 24 MB versus AMD’s 16 MB. Intel’s L1 cache is also larger at 80 KB per core versus 64 KB.

Memory support diverges sharply. AMD supports only DDR5, while Intel supports both DDR4 and DDR5. AMD’s memory bandwidth is listed at 76.8 GB/s; Intel’s is not provided. AMD includes ECC memory support, while Intel does not. PCIe connectivity also differs: AMD offers Gen 4 with 20 CPU lanes, while Intel offers Gen 5 with 8 CPU lanes.

Both chips have integrated graphics, but they are different models: AMD’s Radeon 680M versus Intel’s UHD Graphics 770. Both are unlocked-multiplier-free mobile parts, and both are currently in active production. The AMD chip was released on 2023-03-31, while Intel’s release date was 2023-01-03. Intel has a launch MSRP of $502.

Where Each One Wins

The AMD Ryzen 7 7735HS wins in six benchmark categories, all of which point toward specific use cases. Its 17.1% lead in data encryption makes it the better choice for workloads involving security, VPNs, or encrypted storage. The 14.5% advantage in extended instructions suggests better performance with vector or specialized instruction sets. Integer math (5.4% lead), data compression (4.2% lead), and random string sorting (3.4% lead) all indicate strengths in database, file-handling, and general productivity tasks. The 4.7% win in 3DMark 8-thread performance also shows it handles moderately threaded applications well.

The Intel Core i7-13620H wins in 15 categories, making it the default choice for most users. Its massive 35.8% lead in physics benchmarks and 40.4% lead in prime-number finding shows clear dominance in simulation and mathematical workloads. The 19.9% advantage in floating-point math is critical for scientific computing, 3D rendering, and financial modeling. Single-thread wins of 8.2% to 15.7% across multiple tests mean better responsiveness in everyday tasks like web browsing, office applications, and light productivity. The 13.6% lead in Cinebench R23 multi-core indicates stronger performance in video encoding and 3D rendering.

The Verdict

The data points to a clear overall winner: the Intel Core i7-13620H. It wins 15 of 21 benchmarks, including all single-thread tests and the most demanding multi-core workloads. Its lead in Cinebench R23 multi-core (13.6%) and passmark_physics (35.8%) makes it the preferred choice for content creation, engineering simulation, and any task that relies on raw computational throughput. With a higher boost clock (4.90 GHz) and larger caches (24 MB L3, 2 MB L2 per core), Intel’s architecture consistently translates into faster execution across a broad range of tests.

However, the AMD Ryzen 7 7735HS is not without merit. Its 17.1% lead in data encryption and 14.5% lead in extended instructions make it the better pick for security-focused workloads or applications that use specialized instruction sets. Its lower TDP of 35 W versus Intel’s 45 W also suggests better power efficiency, which may matter for battery life in thin-and-light laptops. The 4.7% win in 3DMark 8-thread performance shows it can hold its own in gaming scenarios that favor moderate thread counts.

Buyers should choose Intel for maximum performance in most scenarios, especially if the workload involves physics, floating-point math, or heavy multi-threaded rendering. Buyers should choose AMD if the primary workload involves encryption, compression, or integer-heavy data processing, or if power efficiency is a higher priority than peak performance. The Intel chip’s $502 launch MSRP is a data point, but the decision should be driven by the benchmark results: Intel for speed, AMD for specialized tasks and efficiency.
