AMD Ryzen 7 5700 vs AMD Ryzen 9 6900HS Comparison

The AMD Ryzen 7 5700 and AMD Ryzen 9 6900HS are both 8-core, 16-thread processors, but they are built for entirely different environments. The Ryzen 7 5700 is a desktop part with a 65 W TDP, while the Ryzen 9 6900HS is a mobile chip with a 35 W TDP. Benchmark data shows a clear split: the desktop Ryzen 7 5700 wins 16 of the 23 head-to-head comparisons, while the mobile Ryzen 9 6900HS takes 7. The nature of those wins, however, reveals more than the raw count.

Where Each One Wins

The AMD Ryzen 7 5700 establishes its dominance in sustained, multi-threaded workloads and single-thread performance. Its most lopsided victories come in Cinebench R23, where it scores 20,655 in multi-core versus 13,445 for the Ryzen 9 6900HS, a margin of 53.6%. It also wins Geekbench multi-core (9,959 vs 9,451) and every PassMark CPU test except physics. The PassMark suite shows consistent leads across integer math (90,091 vs 86,449), floating-point math (51,427 vs 48,239), and data compression (316,699 vs 292,842). Single-thread performance also favors the 5700, with a 10% lead in Geekbench single-core (1,907 vs 1,733) and a 1.8% lead in PassMark single-thread (3,296 vs 3,237). This makes the Ryzen 7 5700 the clear choice for content creation, number crunching, and any workload that scales across cores.

The AMD Ryzen 9 6900HS wins in the 3DMark suite and in specific synthetic physics tests. It takes the 3DMark 16-thread test (6,963 vs 6,628), 4-thread (3,427 vs 3,382), 8-thread (5,830 vs 5,585), max-threads (6,955 vs 6,617), and single-thread (915 vs 901). It also wins Cinebench R15 multi-core (2,161 vs 2,082) and PassMark physics (1,041 vs 984). These wins suggest the 6900HS has a slight edge in bursty, short-duration workloads and in the specific physics simulation used by PassMark. The 3DMark results, in particular, point toward gaming and real-time rendering scenarios where the 6900HS’s higher boost clock of 4.90 GHz comes into play.

Head-to-Head Benchmarks

The largest single win for the AMD Ryzen 7 5700 is in Cinebench R23 single-core, where it scores 2,916 against 1,554 for the 6900HS, an 87.6% advantage. This is a massive gap that cannot be explained by clock speed alone; the 5700 has a lower boost clock (4.60 GHz) than the 6900HS (4.90 GHz), yet it delivers nearly double the performance in this test. This indicates a fundamental architectural efficiency difference. The 5700 also wins Cinebench R23 multi-core by 53.6% (20,655 vs 13,445), and Cinebench R15 single-core by 19.6% (293 vs 245).

The AMD Ryzen 9 6900HS’s biggest wins are smaller in magnitude. Its largest margin is 5.5% in PassMark physics (1,041 vs 984). In 3DMark, it wins by 4.9% in max-threads (6,955 vs 6,617), 4.8% in 16-threads (6,963 vs 6,628), and 4.2% in 8-threads (5,830 vs 5,585). The 6900HS also takes 3DMark single-thread by 1.5% (915 vs 901) and 3DMark 2-threads by a razor-thin 0.1% (1,761 vs 1,762, with the 5700 winning). In Cinebench R15 multi-core, the 6900HS wins by 3.7% (2,161 vs 2,082). These are all modest gains, suggesting the 6900HS is not dramatically faster in its preferred tests, whereas the 5700’s wins are often substantial.

The Verdict

The benchmark data directs each processor to a distinct audience. The AMD Ryzen 7 5700 is the superior performer for multi-threaded desktop workloads, with a commanding 53.6% lead in Cinebench R23 multi-core and consistent wins across the PassMark suite. Its 87.6% advantage in Cinebench R23 single-core also makes it the better choice for lightly-threaded tasks and general responsiveness. The 5700’s higher TDP of 65 W and AM4 socket indicate a desktop build where power draw is not a primary constraint.

The AMD Ryzen 9 6900HS is tailored for mobile systems, with its 35 W TDP and FP7 socket. Its wins in 3DMark and PassMark physics suggest a slight edge in short-burst performance and certain gaming-adjacent workloads. The higher boost clock of 4.90 GHz and faster DDR5 memory bandwidth of 76.8 GB/s contribute to these results. However, its margins of victory are narrow, ranging from 0.1% to 5.5%, compared to the 5700’s often double-digit leads.

Users building a desktop workstation or gaming PC should choose the Ryzen 7 5700, which delivers higher overall average benchmark scores (25,517 vs 25,284) and a higher percentile ranking (78th vs 77th). Users needing a mobile processor for a thin-and-light laptop should consider the Ryzen 9 6900HS, which offers better 3DMark performance and integrated graphics, albeit with lower raw CPU throughput in most tests. The data is unambiguous: the desktop part wins on raw compute, while the mobile part offers a balanced package for its power envelope.
