AMD Ryzen 5 6600H vs AMD Ryzen 7 7735HS Comparison

Head-to-Head Benchmarks

The recorded data leaves no ambiguity about the outcome of this matchup: the AMD Ryzen 7 7735HS wins every single benchmark in the head-to-head comparison, taking all 17 tests. The AMD Ryzen 5 6600H does not claim a single victory, but the margin of defeat varies significantly depending on the workload.

The largest gap appears in PassMark integer math, where the Ryzen 7 scores 85309 against the Ryzen 5's 64927, a difference of 23.9 percent. Floating point math tells a similar story: 47865 versus 36796, a 23.1 percent advantage for the Ryzen 7. These are the two biggest deltas in the entire benchmark set, and both point to the Ryzen 7's superior throughput in arithmetic-heavy tasks. The extra two cores and four threads appear to translate directly into raw compute headroom.

PassMark data encryption shows the Ryzen 7 ahead by 21.7 percent, with scores of 18237 versus 14277. Data compression follows closely at 21.6 percent (293278 versus 229879), and random string sorting trails at 21.4 percent (30388 versus 23888). Extended instructions, a workload that stresses SIMD and specialized instruction paths, gives the Ryzen 7 a 20.7 percent edge (20050 versus 15903). These results cluster tightly, suggesting that the Ryzen 7's advantage scales almost uniformly across memory-bound and instruction-heavy PassMark tests.

Cinebench results reinforce the same pattern. In Cinebench R23 multi-core, the Ryzen 7 scores 13106 against the Ryzen 5's 10322, a 21.2 percent lead. Cinebench R15 multi-core shows a nearly identical gap at 21.9 percent, with the Ryzen 7 posting 2153.4 versus 1681.5. These rendering workloads are highly parallel, so the Ryzen 7's 8 cores and 16 threads versus the Ryzen 5's 6 cores and 12 threads explain the consistent margin.

PassMark multithread gives the Ryzen 7 a 19.4 percent win (23166 versus 18669), while PassMark physics shows a 17 percent gap (1073 versus 891). The physics test is often sensitive to both core count and clock behavior, and here the Ryzen 7's higher boost clock of 4.75 GHz against 4.50 GHz helps push it further ahead.

Single-threaded performance is where the Ryzen 7's advantage narrows considerably. PassMark single-thread shows the Ryzen 7 at 3296 versus 3178, a modest 3.6 percent lead. Cinebench R23 single-core gives the Ryzen 7 a 5.7 percent edge (1546 versus 1458), and Cinebench R15 single-core shows a 5.6 percent gap (248 versus 234). Geekbench single-core lands at 7.8 percent (1699 versus 1566). These are the smallest margins in the dataset. The Ryzen 7's boost advantage of 250 MHz is enough to win, but not by a wide margin, which indicates that the underlying Zen 3+ cores are very close in per-thread capability.

Geekbench multi-core shows an 8.3 percent lead for the Ryzen 7 (8114 versus 7444). That is a smaller multi-core gap than Cinebench or PassMark, which suggests that Geekbench's mixed workload does not scale as aggressively with core count. PassMark find prime numbers, a test that combines integer logic with memory access patterns, gives the Ryzen 7 an 11.9 percent win (59 versus 52).

Where Each One Wins

The data shows a clean sweep for the AMD Ryzen 7 7735HS across every benchmark category. There is no workload in the recorded results where the Ryzen 5 6600H comes out ahead. However, the magnitude of the Ryzen 7's advantage depends heavily on the type of task.

For multi-threaded rendering, video encoding, and parallel compute, the Ryzen 7 is the clear choice. Cinebench R23 multi-core, Cinebench R15 multi-core, and PassMark multithread all show leads between 19.4 and 21.9 percent. Users running CPU-based rendering, 3D scene compilation, or batch processing will see the largest real-world gains from the Ryzen 7. The PassMark integer and floating point math results, with deltas of 23.9 and 23.1 percent, also favor the Ryzen 7 strongly for scientific computing, financial modeling, and any workload that saturates all cores.

For single-threaded responsiveness, the gap narrows but the Ryzen 7 still wins. PassMark single-thread shows only a 3.6 percent difference, and Cinebench R23 single-core shows 5.7 percent. Everyday tasks like web browsing, office document editing, and light application launches depend on single-core performance, and here the two processors are much closer. The Ryzen 5 6600H is not far behind in these scenarios, which means users who prioritize snappy UI response over heavy compute might not notice a dramatic difference.

The Ryzen 5 does have one structural advantage that is not reflected in the benchmark scores: its thermal design power. The Ryzen 5 6600H carries a 45 W TDP, while the Ryzen 7 7735HS is rated at 35 W. In the database, the Ryzen 7 achieves significantly higher scores while drawing less power on paper, which makes it the more efficient performer per watt based on these specifications. However, the Ryzen 5's higher TDP could be a consideration for system integrators designing cooling solutions, as the two chips may behave differently under sustained load depending on chassis thermal limits.

For users who need maximum thread count and the fastest possible multi-core results, the Ryzen 7 7735HS is the obvious pick. For users who want a lighter system with lower power draw and are willing to accept a 20 percent multi-core deficit, the Ryzen 5 6600H remains a viable option, especially in single-threaded workloads where the gap is under 8 percent.

Architecture Differences

Both processors are built on the same Zen 3+ architecture and share the Rembrandt family lineage. The Ryzen 5 6600H uses the Rembrandt codename, while the Ryzen 7 7735HS uses Rembrandt-R, a refresh of the same design. Both are manufactured on TSMC's 6 nm process node, and both use the AMD Socket FP7. The die size differs slightly: the Ryzen 5 measures 208 mm², while the Ryzen 7 measures 210 mm².

The core configurations are the primary architectural differentiator. The Ryzen 5 6600H has 6 cores and 12 threads, while the Ryzen 7 7735HS has 8 cores and 16 threads. That is a 33 percent increase in core count and a 33 percent increase in thread count for the Ryzen 7. The base clocks are close: 3.30 GHz for the Ryzen 5 versus 3.20 GHz for the Ryzen 7. The boost clocks differ more meaningfully, with the Ryzen 7 reaching 4.75 GHz against the Ryzen 5's 4.50 GHz. The Ryzen 7 effectively combines more cores with a higher ceiling, which explains why it wins every benchmark.

Cache layouts are identical in structure. Both chips feature 64 KB of L1 cache per core, 512 KB of L2 cache per core, and 16 MB of shared L3 cache. Because the Ryzen 7 has more cores, it also has more total L1 and L2 cache, but the L3 pool is the same size. This means the Ryzen 7 has to share its 16 MB L3 across 8 cores, while the Ryzen 5 shares the same amount across 6 cores, giving the Ryzen 5 a slightly larger L3-to-core ratio.

Memory support is also identical: both support DDR5 with a dual-channel memory bus and a memory bandwidth of 76.8 GB/s. The PCIe implementation matches as well, with both offering Gen 4 and 20 lanes from the CPU. Neither chip has an unlocked multiplier.

The integrated graphics differ. The Ryzen 5 6600H carries a Radeon 660M, while the Ryzen 7 7735HS steps up to a Radeon 680M. The database does not include iGPU benchmark scores, so the graphics comparison is limited to the specification difference. ECC memory support also differs: the Ryzen 5 does not support ECC, while the Ryzen 7 does. This makes the Ryzen 7 more suitable for error-sensitive workloads that require validated memory integrity.

The Ryzen 7 7735HS has a recorded release date of 2023-03-31, while the Ryzen 5 6600H has no release date in the database. Both parts remain in active production. The Ryzen 7 is listed with two part numbers, 100-000000985(FP7) and 100-000000989(FP7r2), while the Ryzen 5 has a single part number of 100-000000546100-000000562.
