AMD Ryzen 5 5600X3D vs AMD Ryzen 7 7735HS Comparison

The AMD Ryzen 7 7735HS and AMD Ryzen 5 5600X3D represent two fundamentally different approaches to CPU design: one is a power-efficient mobile chip with high core counts, the other a desktop part with a massive cache. Benchmark results show the 7735HS wins 10 of 17 head-to-head tests, while the 5600X3D takes 7, but the nature of those wins reveals a stark split between raw throughput and latency-sensitive workloads. In the data, the 5600X3D dominates in Cinebench R23 multi-core by 29.5% (18603 vs 13106) and single-core by 41.1% (2626 vs 1546), yet the 7735HS counters with a 30.1% lead in PassMark integer math (85309 vs 65587) and a 27.8% advantage in floating-point math (47865 vs 37464). This is not a simple "one is faster" story; it is a tale of two architectures optimized for different arenas.

Head-to-Head Benchmarks

The most lopsided victory for the Ryzen 5 5600X3D comes in Cinebench R23 single-core, where it scores 2626 against the 7735HS’s 1546—a massive 41.1% delta. This is mirrored in Geekbench single-core, where the 5600X3D leads by 18.6% (2086 vs 1699). The 5600X3D also wins Cinebench R23 multi-core by 29.5% (18603 vs 13106), a surprising result given the 7735HS has 8 cores and 16 threads versus the 5600X3D’s 6 cores and 12 threads. The desktop chip’s advantage extends to Geekbench multi-core (9386 vs 8114, a 13.6% lead) and Cinebench R15 single-core, where it wins by 6.1% (264 vs 248).

The 7735HS, however, strikes back hard in synthetic math workloads. Its PassMark integer math score of 85309 beats the 5600X3D’s 65587 by 30.1%. Floating-point math shows a similar story: 47865 vs 37464, a 27.8% win for the mobile chip. In PassMark data compression, the 7735HS posts 293278 versus 247365, a 18.6% advantage. The 7735HS also wins PassMark data encryption by 20.2% (18237 vs 15170) and extended instructions by 17.2% (20050 vs 17102). Random string sorting goes to the 7735HS by 23.5% (30388 vs 24597).

The single-thread PassMark test is close, with the 7735HS edging out the 5600X3D by 3.4% (3296 vs 3187). The 5600X3D’s wins are concentrated in Cinebench and physics. Its PassMark physics score of 2453 crushes the 7735HS’s 1073, a 56.3% delta. The 5600X3D also wins PassMark find prime numbers by 67.4% (181 vs 59), the largest percentage margin in the entire comparison. PassMark multi-thread goes to the 7735HS by a modest 5.8% (23166 vs 21888), showing that the 8-core mobile part holds its own in general multi-threaded throughput.

Where Each One Wins

The Ryzen 5 5600X3D is the clear winner for single-core performance and applications that rely on it. Its Cinebench R23 single-core score is 41.1% higher, and Geekbench single-core is 18.6% higher. This translates to wins in physics simulations (56.3% lead) and prime number finding (67.4% lead), suggesting a strong fit for scientific computing and legacy single-threaded workloads. The 5600X3D also takes Cinebench R23 multi-core by 29.5%, indicating that even in multi-threaded rendering, the desktop part’s higher clock speeds and cache efficiency can overcome the 7735HS’s two extra cores.

The Ryzen 7 7735HS wins in almost every PassMark sub-test, particularly in integer math (30.1% lead), floating-point math (27.8%), data compression (18.6%), and data encryption (20.2%). These results point to strengths in general-purpose computing, database operations, and cryptographic workloads. The 7735HS also wins PassMark multi-thread by 5.8%, showing that its 8-core/16-thread configuration provides a real throughput advantage in mixed workloads. Its single-thread PassMark score is slightly higher (3.4% lead), meaning it is not universally slower in single-core tasks, only in the Cinebench and Geekbench specific tests.

The data suggests the 5600X3D is optimized for latency-sensitive tasks and short bursts of heavy compute, while the 7735HS excels at sustained throughput across diverse instruction sets.

Architecture Differences

The two CPUs are built on different process nodes and microarchitectures. The 7735HS uses a 6 nm process from TSMC, while the 5600X3D uses a 7 nm process, also from TSMC. The 7735HS is based on Zen 3+ architecture (codenamed Rembrandt-R), while the 5600X3D uses the older Zen 3 architecture (codenamed Vermeer). The 7735HS packs 8 cores and 16 threads, whereas the 5600X3D has 6 cores and 12 threads.

The most significant architectural difference is cache. The 5600X3D has a massive 96 MB of shared L3 cache, compared to the 7735HS’s 16 MB. This 6x difference in L3 cache is the primary driver of the 5600X3D’s wins in Cinebench and physics tests, as larger caches reduce memory latency for frequently accessed data. Both CPUs have the same per-core L1 (64 KB) and L2 (512 KB) cache sizes.

Memory support differs fundamentally: the 7735HS uses DDR5 with a memory bandwidth of 76.8 GB/s, while the 5600X3D uses DDR4 with 51.2 GB/s. Both support ECC memory. The 7735HS includes integrated Radeon 680M graphics, while the 5600X3D has no integrated graphics. The 7735HS is a mobile part with a 35W TDP and an AMD Socket FP7, while the 5600X3D is a desktop part with a 105W TDP and AMD Socket AM4. Both use PCIe Gen 4 with 20 lanes (CPU only). The 7735HS is currently Active in production, while the 5600X3D is End-of-life.

The Verdict

The data indicates that the AMD Ryzen 5 5600X3D is the better choice for applications that are heavily dependent on single-core speed and large cache residency. Its 41.1% lead in Cinebench R23 single-core and 29.5% lead in Cinebench R23 multi-core make it the superior part for 3D rendering, physics simulation, and legacy single-threaded software. The 56.3% advantage in PassMark physics and 67.4% lead in find prime numbers further cement its position for scientific and engineering workloads. However, the 5600X3D is End-of-life, so availability may be limited.

The AMD Ryzen 7 7735HS is the more versatile processor for general-purpose computing, particularly in mobile environments. Its 30.1% lead in integer math, 27.8% in floating-point math, and 20.2% in data encryption make it superior for database operations, cryptographic tasks, and mixed workstation workloads. The 5.8% win in PassMark multi-thread shows it can handle concurrent tasks effectively. Its lower TDP (35W vs 105W) and integrated Radeon 680M graphics make it suitable for laptops and compact systems. The 7735HS is currently Active in production.

The verdict is straightforward: choose the 5600X3D for raw compute density in cache-sensitive desktop tasks, particularly if you are building a new AM4 system and can find the part. Choose the 7735HS if you need a power-efficient, multi-core-capable processor with integrated graphics for a mobile or space-constrained build. The 5600X3D’s overall average benchmark score (25365) is slightly higher than the 7735HS’s (25147), but the 7735HS’s wins in 10 of 17 head-to-head tests show it is the more balanced performer across a wider range of tasks.
