AMD Ryzen 5 6600H vs AMD Ryzen 7 7730U Comparison

The AMD Ryzen 7 7730U and AMD Ryzen 5 6600H are two mobile processors that, despite different core counts and power targets, land within 0.3% of each other in average benchmark score. The Ryzen 7 7730U averages 25625 points against the Ryzen 5 6600H’s 25550 points, placing both at the 78th percentile of all CPUs. This near-parity is remarkable given the specification sheet differences, but the benchmark breakdown reveals distinct strengths that diverge sharply by workload type.

Head-to-Head Benchmarks

The Ryzen 7 7730U wins four of the seventeen head-to-head comparisons, and its victories are concentrated in multi-core rendering and math-heavy integer work. In Cinebench R15 multi-core, the 7730U scores 1830 against the 6600H’s 1681.5, an 8.8% advantage. Cinebench R23 multi-core shows a similar but narrower lead: 10801.5 versus 10322, a 4.6% edge. The 7730U also takes PassMark floating point math with 38460 to 36796 (4.5% higher) and PassMark integer math with 72352 to 64927, its largest win at 11.4%. These results align with the 7730U’s eight cores and sixteen threads versus the 6600H’s six cores and twelve threads.

The Ryzen 5 6600H dominates the remaining thirteen benchmarks, and its wins are often substantial. The most striking is Geekbench multi-core, where the 6600H scores 7444 versus the 7730U’s 6565, an 11.8% margin that reverses the Cinebench trend. PassMark physics shows a 15.7% lead (891 versus 751), and PassMark find prime numbers favors the 6600H by 13.5% (52 versus 45). Single-threaded performance also belongs to the 6600H: Cinebench R15 single-core is 234 versus 231 (1.3% higher), Cinebench R23 single-core is 1458 versus 1454.5 (0.2% higher), Geekbench single-core is 1566 versus 1541 (1.6% higher), and PassMark single-thread is 3178 versus 3004 (5.5% higher).

The 6600H also wins in memory-sensitive and encryption workloads. PassMark data compression goes to the 6600H at 229879 versus 225023 (2.1% higher), and PassMark data encryption is nearly tied at 14277 versus 14258 (0.1% higher).

PassMark multithread also goes to the 6600H: 18669 versus 18037, a 3.4% advantage despite the 7730U’s extra two cores. The overall win count is lopsided at 13 to 4 in favor of the 6600H, but the average scores remain within 0.3%, indicating that the 7730U’s wins come in higher-impact workloads.

FAQ

Q: Which processor has a higher average benchmark score?

A: The AMD Ryzen 7 7730U averages 25625 points, which is 0.3% higher than the AMD Ryzen 5 6600H’s 25550 points. Both sit at the 78th percentile of all CPUs.

Q: Why does the Ryzen 7 7730U win multi-core Cinebench but lose Geekbench multi-core?

A: The 7730U leads in Cinebench R23 multi-core with 10801.5 versus 10322 (4.6% higher), but the 6600H wins Geekbench multi-core with 7444 versus 6565 (11.8% higher). The data shows workload-specific scaling: the 7730U’s eight cores help in Cinebench’s rendering pipeline, while the 6600H’s higher base clock of 3.30 GHz versus 2.00 GHz appears to benefit Geekbench’s workload mix.

Q: Is the Ryzen 5 6600H always faster in single-threaded tests?

A: Yes, the 6600H wins every single-threaded comparison. It leads in Cinebench R15 single-core (234 versus 231), Cinebench R23 single-core (1458 versus 1454.5), Geekbench single-core (1566 versus 1541), and PassMark single-thread (3178 versus 3004). The margins range from 0.2% to 5.5%.

Q: Which processor has better integrated graphics?

A: The Ryzen 7 7730U features Radeon Graphics (Vega 8), while the Ryzen 5 6600H has Radeon 660M. The benchmark data does not include graphics-specific tests, so no performance comparison can be made from the provided scores.

Architecture Differences

The two processors come from different architectural generations. The Ryzen 7 7730U uses Zen 3 with the codename Barcelo-R, while the Ryzen 5 6600H uses Zen 3+ with the codename Rembrandt. This architectural shift is accompanied by a process node change: the 7730U is built on TSMC’s 7 nm process, while the 6600H uses TSMC’s 6 nm process. The die sizes differ as well, with the 7730U measuring 180 mm² versus the 6600H’s 208 mm².

The transistor count is listed only for the 7730U at 10,700 million; no comparable figure is provided for the 6600H. Both processors share identical cache layouts: 64 KB of L1 per core, 512 KB of L2 per core, and 16 MB of shared L3. However, the core counts diverge — the 7730U has eight cores and sixteen threads, while the 6600H has six cores and twelve threads. This two-core difference is partially offset by the 6600H’s higher base clock of 3.30 GHz versus 2.00 GHz, though both boost to 4.50 GHz.

Memory support is a major architectural split. The 7730U supports DDR4 over a dual-channel bus with 51.2 GB/s bandwidth, while the 6600H supports DDR5 with 76.8 GB/s. The 7730U also supports ECC memory, which the 6600H does not. PCIe connectivity differs: the 7730U offers Gen 3 with 16 lanes, while the 6600H offers Gen 4 with 20 lanes. Sockets are incompatible, with the 7730U using AMD Socket FP6 and the 6600H using AMD Socket FP7.

Specification Differences

The core and thread counts are the most obvious difference: the 7730U provides eight cores and sixteen threads, while the 6600H provides six cores and twelve threads. Base clocks differ substantially, with the 7730U at 2000 MHz and the 6600H at 3300 MHz, though both reach a 4500 MHz boost. TDP is another clear divider: the 7730U is rated at 15 watts, the 6600H at 45 watts.

Memory support separates the two further. The 7730U uses DDR4 with 51.2 GB/s bandwidth, while the 6600H uses DDR5 with 76.8 GB/s. ECC memory is supported only on the 7730U. PCIe generation and lane counts differ: the 7730U has Gen 3 with 16 lanes, the 6600H has Gen 4 with 20 lanes. The integrated graphics units are different models, with the 7730U featuring Radeon Graphics (Vega 8) and the 6600H featuring Radeon 660M. The process node is 7 nm for the 7730U and 6 nm for the 6600H, with die sizes of 180 mm² and 208 mm² respectively. The 7730U has a listed transistor count of 10,700 million, while the 6600H has no listed value. Sockets are FP6 for the 7730U and FP7 for the 6600H.

Where Each One Wins

The Ryzen 7 7730U wins in multi-core rendering and integer math. Its Cinebench R15 multi-core score of 1830 is 8.8% higher than the 6600H’s 1681.5, and its Cinebench R23 multi-core score of 10801.5 is 4.6% higher. PassMark integer math favors the 7730U by 11.4% (72352 versus 64927), and PassMark floating point math goes to the 7730U by 4.5% (38460 versus 36796). These wins make the 7730U the better choice for workloads that scale with core count, such as video rendering and parallel integer calculations.

The Ryzen 5 6600H wins in a broader range of categories, including single-threaded performance, physics simulations, and memory-intensive tasks. Its Geekbench multi-core lead of 11.8% (7444 versus 6565) is notable, as is its 15.7% advantage in PassMark physics (891 versus 751). The 6600H also leads in PassMark multithread by 3.4% (18669 versus 18037) despite having fewer cores, suggesting that its higher base clock and DDR5 bandwidth compensate. Single-threaded workloads are uniformly better on the 6600H, with leads ranging from 0.2% in Cinebench R23 to 5.5% in PassMark. The 6600H also takes data compression, encryption, extended instructions, find prime numbers, and random string sorting.

The Verdict

The data presents a clear split: the Ryzen 7 7730U is the pick for workloads that leverage its eight cores and sixteen threads, particularly in Cinebench rendering and integer math, where it leads by up to 11.4%. Its 15-watt TDP also makes it suitable for thinner, lower-power laptops, and its ECC memory support adds a niche advantage for data integrity.

The Ryzen 5 6600H is the pick for single-threaded performance and memory-bandwidth-sensitive tasks. It wins thirteen of seventeen benchmarks, including all single-threaded tests and a decisive 11.8% lead in Geekbench multi-core. Its 45-watt TDP and DDR5 support with 76.8 GB/s bandwidth make it the stronger option for systems that can accommodate higher power draw and demand faster memory access.

Given the average scores are within 0.3% (25625 versus 25550), neither processor is a categorical winner. The choice depends entirely on workload priority: the 7730U for core-heavy rendering and math, the 6600H for general responsiveness, physics, and memory throughput. Both sit at the 78th percentile, confirming that the 6600H’s architectural advantages in clock speed and memory offset the 7730U’s core-count advantage in overall terms.
