AMD Ryzen 5 5600X3D vs Intel Core i7-13620H Comparison

Head-to-Head Benchmarks

The head-to-head data shows a split result: the Intel Core i7-13620H wins 12 of the 17 recorded comparisons, while the AMD Ryzen 5 5600X3D takes 5. The largest Intel victory comes in PassMark floating point math, where the i7-13620H scores 59,762 against 37,464, a 37.3% advantage. That is the widest gap in either direction across the entire benchmark set. The Intel part also leads in PassMark integer math by 19% (80,948 versus 65,587) and in Cinebench R15 multi-core by 17.8% (2,281 versus 1,875). In PassMark single-thread, the i7-13620H posts 3,589 versus 3,187, an 11.2% edge.

The AMD Ryzen 5 5600X3D counters with its own decisive wins. In Cinebench R23 single-core, it scores 2,626 against 1,833, a 43.3% advantage, the largest single-core margin in the comparison. The R23 multi-core result also favors AMD: 18,603 versus 15,176, a 22.6% lead. PassMark find prime numbers shows an 82.8% gap (181 versus 99), and PassMark physics gives AMD a 46.8% edge (2,453 versus 1,671). Cinebench R15 single-core is nearly tied, with AMD ahead by just 0.4% (264 versus 263).

The pattern is clear: Intel dominates in floating point, integer math, compression, sorting, and overall multi-threaded throughput, while AMD wins in the two most recent Cinebench versions, prime number finding, and physics calculations. Notably, the Cinebench results contradict each other across versions. In R15 and R20 multi-core, Intel leads by 17.8% and 5.9% respectively, but in R23 multi-core, AMD leads by 22.6%. This suggests workload-specific scaling behavior rather than a general multi-core advantage for either part.

Architecture Differences

The AMD Ryzen 5 5600X3D is a desktop processor built on TSMC's 7 nm process, using the Zen 3 architecture with the Vermeer codename. It features 6 cores and 12 threads, a base clock of 3.30 GHz, and a boost clock of 4.40 GHz. Its defining characteristic is a large 96 MB shared L3 cache, which is the source of the "X3D" designation. The cache hierarchy includes 64 KB L1 per core and 512 KB L2 per core. It supports DDR4 memory in dual-channel configuration with a recorded bandwidth of 51.2 GB/s, and it supports ECC memory. The processor uses AMD Socket AM4 and provides PCIe Gen 4 with 20 lanes from the CPU. It has no integrated graphics.

The Intel Core i7-13620H is a mobile processor built on Intel's 10 nm process, using the Raptor Lake architecture with the Raptor Lake-H codename. It offers 10 cores and 16 threads, a base clock of 2.40 GHz, and a boost clock of 4.90 GHz. Its L3 cache is 24 MB shared, considerably smaller than AMD's 96 MB. The L1 cache is 80 KB per core and L2 is 2 MB per core. It supports both DDR4 and DDR5 memory in dual-channel configuration, but the database does not record a memory bandwidth figure for this part. ECC memory is not supported. The socket is Intel BGA 1744, and PCIe support is Gen 5 with 8 lanes from the CPU. This processor includes integrated graphics: UHD Graphics 770.

The core count difference (10 versus 6) and thread count difference (16 versus 12) explain much of Intel's multi-threaded wins in certain tests. However, the AMD part's much larger L3 cache likely explains its wins in Cinebench R23 and physics, where cache-sensitive workloads benefit from the 96 MB shared pool. The Intel part compensates with a higher boost clock (4.90 GHz versus 4.40 GHz) and a 2 MB per-core L2, which aids single-threaded and math-heavy tasks.

The Verdict

The data does not crown a single winner; it separates them by use case. The Intel Core i7-13620H is the stronger choice for broadly multi-threaded workloads that resemble PassMark's integer math, floating point, compression, and sorting tests. It wins those by margins ranging from 2.3% to 37.3%. The AMD Ryzen 5 5600X3D is the better option for workloads that mirror Cinebench R23, prime number finding, and physics simulations, where its large L3 cache provides advantages up to 82.8%.

The average benchmark scores place the AMD part at 25,365 and the Intel part at 24,911. Both sit at the 77th percentile against all CPUs. The nearest rivals for the AMD part include the Intel Core 5 120 (delta 0%), the Intel Core i7-11700KF (delta -0.2%), and the AMD Ryzen 7 7840U (delta -0.3%). For the Intel part, the nearest rivals are the Intel Core i7-11850H (delta -0.1%), the Intel Core 5 210H (delta 0.2%), and the AMD Ryzen 5 7500F (delta -0.2%). These figures indicate that both processors sit in a tightly contested performance band, with the AMD part holding a slight overall average edge of 454 points (about 1.8%).

For a desktop system where Cinebench R23 performance and physics calculations matter, the AMD part is the data-backed pick. For mobile systems where PassMark's math, compression, and sorting workloads dominate, the Intel part leads. The Intel part also offers integrated graphics, which the AMD part lacks, making it suitable for systems without a discrete GPU.

It also dominates PassMark floating point math (59,762 versus 37,464, 37.3%), integer math (80,948 versus 65,587, 19%), data compression (281,335 versus 247,365, 12.1%), random string sorting (29,395 versus 24,597, 16.3%), and single-thread (3,589 versus 3,187, 11.2%). Smaller wins appear in data encryption (15,568 versus 15,170, 2.6%) and extended instructions (17,513 versus 17,102, 2.3%). The PassMark multithread test also favors Intel (24,192 versus 21,888, 9.5%).

For a desktop build focused on the latest Cinebench version, physics, or prime number heavy computation, the AMD Ryzen 5 5600X3D is the data-backed selection. For a mobile platform handling general math, compression, sorting, and encryption, the Intel Core i7-13620H delivers more consistent wins. The Intel part also provides integrated graphics, making it viable in systems without a discrete GPU. The AMD part's end-of-life status and higher TDP (105 W versus 45 W) further position it as a desktop-only option, while the Intel part targets portable systems with active production status.
