AMD Ryzen 7 7735HS vs AMD Ryzen 9 5900HX Comparison

The data is decisive: the AMD Ryzen 7 7735HS wins 20 of 23 head-to-head benchmarks against the AMD Ryzen 9 5900HX. The 5900HX claims only three victories, two of which are substantial, but the overall benchmark pattern favors the newer 7000-series part. Despite the 5900HX carrying the higher-tier "Ryzen 9" badge, benchmark results indicate the 7735HS is the faster processor in the majority of workloads tested.

Head-to-Head Benchmarks

The 7735HS establishes its dominance early in the 3DMark suite. Across all six 3DMark thread-count tests, the 7735HS wins every round. The smallest margin is a 2.9% lead in the 4-thread test (3382 vs 3285), while the largest advantage is a 5.6% delta in the max-threads test (6872 vs 6487). The 16-thread and 8-thread tests also show clear 5.5% and 5.1% leads for the 7735HS, respectively. This pattern suggests the 7735HS scales better with thread utilization in synthetic graphics and physics workloads.

Cinebench results reinforce the 7735HS advantage, though with narrower margins. In Cinebench R23 multi-core, the 7735HS scores 13106 against the 5900HX’s 12845, a 2% delta. The single-core R23 test shows a 3.8% lead for the 7735HS (1546 vs 1488). Cinebench R15 tells a similar story: a 2.2% multi-core win (2153.4 vs 2106) and a 3.2% single-core win (248 vs 240) for the 7735HS. These are consistent, if modest, victories.

The 5900HX fights back in Geekbench, where it posts its most significant wins. In Geekbench multi-core, the 5900HX scores 8720 against the 7735HS’s 8114, a commanding 7.5% lead. The single-core Geekbench test also favors the 5900HX, with a 5.5% margin (1792 vs 1699). These results stand in contrast to the Cinebench and 3DMark outcomes, indicating that the benchmark methodology heavily influences which processor appears superior.

PassMark results are mostly 7735HS wins, but the margins vary widely. The 7735HS takes the physics test by a massive 15.3% (1073 vs 909) and the prime-number finding test by 10.2% (59 vs 53). Other PassMark wins for the 7735HS include multi-thread (3.6% lead, 23166 vs 22326), extended instructions (2.8% lead), and data compression (1.9% lead). The 5900HX counters with a 1.7% win in integer math (86735 vs 85309), while floating-point math is nearly a tie, with the 7735HS ahead by just 0.6% (47865 vs 47556).

Where Each One Wins

The 7735HS is the clear winner for sustained multi-threaded workloads and raw computational throughput. Its victories in 3DMark, Cinebench, and most PassMark tests point to superior performance in rendering, physics simulation, and general productivity tasks. The 15.3% lead in PassMark physics and 10.2% lead in prime-number finding are particularly notable, suggesting the 7735HS has a meaningful edge in mathematical and simulation-heavy applications. The 2% advantage in Cinebench R23 multi-core indicates that video rendering and 3D modeling will be faster on the 7735HS, albeit not by a dramatic margin.

The 5900HX wins are concentrated in Geekbench, where it leads by 7.5% multi-core and 5.5% single-core. This suggests the 5900HX has an advantage in workloads that resemble Geekbench’s test patterns, which often involve real-world application scenarios like image processing and file compression. The 5900HX also edges out the 7735HS in PassMark integer math by 1.7%, indicating a slight preference for integer-based calculations. For users whose primary applications align with Geekbench-style tasks, the 5900HX may still be the better choice.

Single-threaded performance is broadly split. The 7735HS wins 3DMark single-thread (912 vs 881, 3.4% lead), Cinebench R23 single-core (1546 vs 1488, 3.8% lead), and PassMark single-thread (3296 vs 3178, 3.6% lead). However, the 5900HX takes Geekbench single-core with a 5.5% margin. This split means that for most single-threaded applications, the 7735HS holds an edge, but the 5900HX is not without its own strengths in this category.

Architecture Differences

The two processors are built on different architectures and process nodes. The 5900HX uses the Zen 3 architecture on TSMC’s 7 nm process, with a codename of Cezanne. The 7735HS uses Zen 3+ on a 6 nm TSMC node, with the codename Rembrandt-R. The die sizes differ notably: the 5900HX measures 180 mm², while the 7735HS is larger at 210 mm². The transistor count is listed for the 5900HX at 10,700 million, but no transistor count is provided for the 7735HS.

Both processors feature 8 cores and 16 threads. Cache configurations are identical: 64 KB of L1 per core, 512 KB of L2 per core, and 16 MB of shared L3. The base clocks are close, with the 5900HX at 3.30 GHz and the 7735HS slightly lower at 3.20 GHz. However, the boost clock favors the 7735HS, which reaches 4.75 GHz versus the 5900HX’s 4.60 GHz. The TDP also differs, with the 5900HX rated at 45W and the 7735HS at a lower 35W.

Memory support is a major divergence. The 5900HX supports DDR4 memory with dual-channel configuration, offering 68.3 GB/s of bandwidth. The 7735HS supports DDR5 with dual-channel configuration, providing 76.8 GB/s of bandwidth. The 7735HS also supports ECC memory, while the 5900HX does not. PCIe connectivity differs as well: the 5900HX uses Gen 3, while the 7735HS uses Gen 4 with 20 lanes (CPU only).

Integrated graphics are another key difference. The 5900HX features Radeon Vega 8 graphics, while the 7735HS comes with Radeon 680M graphics. The sockets are different too: the 5900HX uses AMD Socket FP6, and the 7735HS uses AMD Socket FP7. The 5900HX has an unlocked multiplier, whereas the 7735HS does not. Both processors are currently marked as Active in production status.

The Verdict

The data supports selecting the AMD Ryzen 7 7735HS for most users. It wins 20 of 23 head-to-head benchmarks, including decisive victories in physics (15.3% lead) and prime-number finding (10.2% lead). Its higher boost clock of 4.75 GHz, DDR5 memory support with 76.8 GB/s bandwidth, and larger 210 mm² die all contribute to its benchmark dominance. The 7735HS also offers ECC memory support and PCIe Gen 4 connectivity, making it the more modern and feature-complete option. Its lower 35W TDP is a bonus for laptop battery life without sacrificing performance in most tests.

The AMD Ryzen 9 5900HX is the pick only for specific use cases where Geekbench-style performance matters most. Its 7.5% lead in Geekbench multi-core and 5.5% lead in single-core are significant, and its 1.7% win in integer math suggests a slight edge in integer-heavy tasks. The unlocked multiplier is also a differentiator for enthusiasts who want overclocking capability, though this is less relevant in a mobile context. For users whose software stack closely mirrors Geekbench’s workload patterns, the 5900HX may still be the better choice despite losing the overall benchmark war.

The 7735HS also holds a notable advantage in single-threaded performance across the majority of tests, winning 3DMark, Cinebench R23, and PassMark single-thread benchmarks by margins ranging from 3.4% to 3.8%. This consistency, combined with its multi-threaded wins, makes it the more balanced performer. The 5900HX’s single Geekbench single-core win cannot offset the 7735HS’s broader success. Benchmark results indicate that the 7735HS is the faster processor for the vast majority of workloads.
