AMD Ryzen 7 7730U vs AMD Ryzen 9 6900HS Comparison

The AMD Ryzen 7 7730U and AMD Ryzen 9 6900HS are both 8-core, 16-thread mobile processors from AMD, but they target different performance envelopes within the laptop market. The benchmark database records a clear separation between them, with the Ryzen 9 6900HS winning all 17 head-to-head comparisons. The Ryzen 7 7730U, however, holds its own in efficiency-oriented workloads, and its average benchmark score of 25625 actually slightly edges out the Ryzen 9 6900HS’s 25284, despite losing every direct test. This apparent contradiction stems from the different benchmark suites recorded for each chip, making the head-to-head results the more reliable comparison.

Head-to-Head Benchmarks

The most significant gap between the two processors appears in Geekbench multicore performance. The Ryzen 9 6900HS scores 9451, which is 30.5% higher than the Ryzen 7 7730U’s 6565. This is the largest percentage difference in any recorded test, and it indicates that the 6900HS is substantially better at handling heavily threaded workloads that scale well across all cores. The Cinebench R23 multicore test tells a similar story, with the 6900HS scoring 13445 versus 10801.5 for the 7730U, a 19.7% advantage.

Physics-based workloads also favor the Ryzen 9 significantly. The Passmark physics test shows the 6900HS at 1041, which is 27.9% ahead of the 7730U’s 751. This suggests better sustained performance under computational stress, likely related to the higher power envelope and clock speeds of the 6900HS. Extended instruction workloads, which often involve AVX or similar vectorized operations, show a 27% gap, with the 6900HS scoring 20015 against 14619.

The Ryzen 9 6900HS also leads in memory-sensitive tasks. Passmark data compression shows the 6900HS at 292842 versus 225023 for the 7730U, a 23.2% difference. Data encryption follows a similar pattern, with the 6900HS achieving 18303 versus 14258, a 22.1% gap. These results are consistent with the 6900HS’s faster memory bandwidth, which is recorded at 76.8 GB/s compared to the 7730U’s 51.2 GB/s.

Single-thread performance is closer, but the 6900HS still wins every test. In Cinebench R23 single-core, the 6900HS scores 1554 against 1454.5, a 6.4% advantage. Geekbench single-core shows 1733 versus 1541, an 11.1% gap. Passmark single-thread records 3237 versus 3004, a 7.2% difference. Cinebench R15 single-core shows the smallest margin at 5.7%, with scores of 245 and 231. These results indicate that the 6900HS has a modest but consistent IPC and clock advantage in lightly threaded tasks.

Floating-point math also favors the Ryzen 9, with a score of 48239 versus 38460, a 20.3% lead. Integer math shows a smaller gap at 16.3%, with scores of 86449 and 72352. Multithreaded Passmark scores put the 6900HS at 23152 versus 18037, a 22.1% difference. Random string sorting shows a 22.5% gap, with scores of 30528 and 23651. Even the find prime numbers test, which often favors older architectures, shows the 6900HS ahead by 22.4%, scoring 58 versus 45.

The Ryzen 7 7730U does not win a single recorded head-to-head comparison. Its closest results are in single-core tests, where it trails by roughly 6 to 11 percent, and in Cinebench R15 multicore, where the 6900HS leads by 15.3%. The data shows a consistent, if variable, performance advantage for the 6900HS across all workload types.

Architecture Differences

The two processors come from different architectural families. The Ryzen 7 7730U is based on Zen 3, with the codename Barcelo-R, and belongs to the 7000 series. The Ryzen 9 6900HS is based on Zen 3+, with the codename Rembrandt, and belongs to the 6000 series. Zen 3+ is an optimized version of Zen 3, with improvements in power management and memory support, although the core microarchitecture remains largely similar.

The manufacturing process differs, with the 7730U using a 7 nm node and the 6900HS using a 6 nm node, both from TSMC. The die size also varies: the 7730U has a die size of 180 mm², while the 6900HS is larger at 208 mm². The transistor count is recorded for the 7730U at 10,700 million, but no transistor count is listed for the 6900HS.

Cache hierarchies are identical in structure. Both processors feature 64 KB of L1 cache per core, 512 KB of L2 cache per core, and 16 MB of shared L3 cache. Neither chip has any 3D V-Cache. This means that differences in cache-sensitive workloads are likely due to memory bandwidth and clock speeds rather than cache capacity.

Memory support is a major architectural difference. The 7730U uses DDR4 memory, while the 6900HS uses DDR5. Both are dual-channel, but the 6900HS achieves a significantly higher memory bandwidth of 76.8 GB/s versus 51.2 GB/s for the 7730U. This is a direct consequence of the newer memory standard and the Zen 3+ architecture’s integrated memory controller.

PCIe support also differs. The 7730U has PCIe Gen 3 with 16 lanes from the CPU, while the 6900HS has PCIe Gen 4 with 20 lanes from the CPU. This gives the 6900HS both higher bandwidth per lane and more total lanes for connecting discrete GPUs or NVMe storage.

Error correction code (ECC) memory support is present on the 7730U but absent on the 6900HS. This is notable for workstation or server-adjacent use cases, though both chips are classified as mobile processors.

The integrated graphics differ as well. The 7730U uses Radeon Graphics (Vega 8), while the 6900HS uses Radeon 680M. The 680M is based on a newer graphics architecture and is designed to deliver higher performance in integrated graphics scenarios, though the database does not include specific iGPU benchmarks.

The Verdict

The benchmark data is unambiguous in direct comparisons. The AMD Ryzen 9 6900HS outperforms the AMD Ryzen 7 7730U in every recorded test, from single-core workloads to heavily threaded tasks. The largest advantages are in multicore performance, where the 6900HS leads by 30.5% in Geekbench multicore and 19.7% in Cinebench R23 multicore. Even in the closest tests, such as Cinebench R15 single-core, the 6900HS maintains a 5.7% lead.

The Ryzen 9 6900HS is the clear choice for anyone prioritizing raw performance, particularly in multi-threaded applications like video rendering, data compression, or scientific computing. Its higher TDP of 35 watts and faster memory support (DDR5 with 76.8 GB/s bandwidth) provide the foundation for these results. The 6900HS also offers PCIe Gen 4 with 20 lanes, which is better suited for modern discrete GPUs and high-speed storage.

The Ryzen 7 7730U, however, is not without merit. Its 15-watt TDP is less than half that of the 6900HS, making it more suitable for thin-and-light laptops where battery life and thermals are priorities. It still delivers respectable performance, with an average benchmark score of 25625 that is actually slightly higher than the 6900HS’s 25284, though this is due to different benchmark suites rather than direct parity. The 7730U also supports ECC memory, which is a rare feature in mobile processors and could matter for specific professional applications.

For users who need maximum compute throughput, the Ryzen 9 6900HS is the superior part. The data shows no scenario where the 7730U wins. For users who prioritize efficiency, the 7730U’s lower power draw and adequate performance make it a sensible option, especially in laptops without robust cooling solutions. The choice ultimately depends on whether the workload demands the 6900HS’s higher sustained performance or the 7730U’s lower power consumption. Given the performance gaps recorded, the 6900HS is the more capable processor for demanding tasks, while the 7730U serves as a more power-conscious alternative.
