AMD Ryzen 7 7735U vs AMD Ryzen 7 PRO 6850HS Comparison

The AMD Ryzen 7 PRO 6850HS and the AMD Ryzen 7 7735U are two 8-core mobile processors sharing the same Zen 3+ architecture, yet the benchmark data reveals a decisive performance gap between them. Despite the 7735U’s newer 7000-series branding, the 6850HS consistently outperforms it across every single benchmark recorded, winning all 17 head-to-head comparisons. The margin is not uniform, however, ranging from a modest 1.8% in prime number finding to a staggering 88.2% in multi-core rendering, indicating that the performance delta is heavily workload-dependent.

Head-to-Head Benchmarks

The most dramatic divergence occurs in Cinebench R23 multi-core, where the 6850HS scores 18,980 against the 7735U’s 10,085. That is an 88.2% advantage, a near-doubling of multi-threaded rendering throughput. The single-core R23 result tells a similar story, with the 6850HS at 2,679 versus 1,490, a 79.8% lead. These are not minor gains; they position the 6850HS in a completely different performance class for heavily threaded workloads like video encoding or 3D rendering.

The older Cinebench R15 benchmark shows a narrower but still substantial gap. In R15 multi-core, the 6850HS posts 1,913 against the 7735U’s 1,698, a 12.7% win. The R15 single-core test sees the 6850HS at 270 versus 234, a 15.4% advantage. This pattern suggests that newer Cinebench versions amplify the architectural or power differences between the two chips, while older tests compress the gap.

Geekbench results reinforce the 6850HS’s dominance. In multi-core, the 6850HS scores 8,429 versus 7,216, a 16.8% lead. The single-core Geekbench result shows 1,869 for the 6850HS against 1,442 for the 7735U, a 29.6% advantage. These synthetic workloads confirm that the 6850HS offers superior both single-threaded and multi-threaded performance, not just in rendering-specific tests.

PassMark’s suite of micro-benchmarks tells a more nuanced story. The largest wins for the 6850HS come in extended instructions (18,091 vs 16,349, +10.7%) and data encryption (17,350 vs 15,825, +9.6%). Data compression shows an 8.9% edge (272,838 vs 250,457), while floating point math is 8.7% ahead (46,706 vs 42,966). Random string sorting yields an 8.8% lead (28,693 vs 26,365). Integer math is closer at 7.4% (85,459 vs 79,580), and the multithread score shows a 7.8% gap (22,330 vs 20,723). Physics testing shows a 6.9% difference (1,065 vs 996).

The narrowest margins appear in prime number finding, where the 6850HS scores 58 versus 57, a mere 1.8% edge, and in PassMark single-thread, where the 6850HS scores 3,301 against 3,236, a 2% lead. These small deltas suggest that for simple, latency-bound integer operations, the two processors are nearly identical, likely due to the same core architecture and similar boost clocks.

Architecture Differences

Both processors are built on TSMC’s 6 nm process node and feature the same 208 mm² die size. They share the Zen 3+ architecture with the Rembrandt codename family, though the 7735U is specifically designated as Rembrandt-R, suggesting a refined or refreshed variant. Both have 8 cores and 16 threads, with identical cache hierarchies: 64 KB of L1 per core, 512 KB of L2 per core, and 16 MB of shared L3.

The core clock speeds differ notably. The 6850HS has a base clock of 3.20 GHz and a boost clock of 4.70 GHz. The 7735U runs lower at a 2.70 GHz base but slightly higher at 4.75 GHz boost. This means the 7735U can briefly reach a higher single-thread peak, yet the 6850HS maintains a significantly higher sustained base frequency, which explains its large multi-core advantages.

The thermal design point differs, with the 6850HS rated at 35 W and the 7735U at 28 W. This 7 W gap in power envelope is a primary driver of the performance difference, as the 6850HS can sustain higher clocks under load. Both processors use AMD Socket FP7 and support DDR5 memory in dual-channel configuration with a memory bandwidth of 76.8 GB/s. They both offer PCIe Gen 4 with 20 lanes (CPU only) and integrate the same Radeon 680M graphics.

The most surprising architectural difference is ECC memory support. The 7735U supports ECC memory, while the 6850HS does not. This is an unusual feature for a mobile processor and could make the 7735U more appealing for specific reliability-focused workloads, despite its lower performance. Both are active in production, with the 6850HS released in April 2022 and the 7735U in January 2023.

FAQ

Q: Which processor is faster in multi-core rendering?

A: The AMD Ryzen 7 PRO 6850HS is significantly faster, scoring 18,980 in Cinebench R23 multi-core versus the 7735U’s 10,085, an 88.2% advantage.

Q: Is the Ryzen 7 7735U better at anything?

A: The data shows no benchmark wins for the 7735U. The 6850HS wins all 17 recorded head-to-head tests. The 7735U does support ECC memory, a feature the 6850HS lacks, but this does not translate into a performance advantage.

Q: How do their single-core performances compare?

A: The 6850HS leads in every single-core test. In Cinebench R23 single-core, it scores 2,679 versus 1,490, a 79.8% margin. In PassMark single-thread, the lead narrows to 2% (3,301 vs 3,236), showing less differentiation in simple tasks.

Q: Why does the 7735U have a higher boost clock but lower performance?

A: The 7735U boosts to 4.75 GHz versus the 6850HS’s 4.70 GHz, but it has a much lower base clock of 2.70 GHz versus 3.20 GHz. The 6850HS also has a higher 35 W TDP versus 28 W, allowing it to sustain higher clocks for longer periods under multi-threaded loads.

Q: Do both processors have the same integrated graphics?

A: Yes, both integrate the Radeon 680M GPU. They also share identical memory bandwidth of 76.8 GB/s and support dual-channel DDR5.

Q: Are these processors from the same generation?

A: They share the same Zen 3+ architecture and Rembrandt codename, though the 7735U is labeled as Rembrandt-R and belongs to the 7000 series, while the 6850HS is from the 6000 series. Both use the same 6 nm TSMC process and 208 mm² die.

Specification Differences

The two processors differ in several key specification fields. The base clock varies, with the 6850HS at 3.20 GHz and the 7735U at 2.70 GHz. The boost clock also differs, at 4.70 GHz for the 6850HS and 4.75 GHz for the 7735U. The TDP is another point of divergence, with the 6850HS rated at 35 W and the 7735U at 28 W.

ECC memory support is a differentiator, as the 7735U supports ECC while the 6850HS does not. The release dates differ, with the 6850HS launching in April 2022 and the 7735U in January 2023. The part numbers also vary, with the 6850HS using 100-000000542100-000000564 and the 7735U using 100-000000987(FP7)100-000000991(FP7r2). The series naming differs (6000 series vs 7000 series) and the codename is slightly different (Rembrandt vs Rembrandt-R). The production status and all other specifications, including cache, memory support, PCIe lanes, and integrated graphics, are identical.

The Verdict

The benchmark data is unambiguous: the AMD Ryzen 7 PRO 6850HS is the superior performer in nearly every measurable way. It holds an 80th percentile ranking among all CPUs, the same as the 7735U, but its average benchmark score of 28,549 is higher than the 7735U’s 28,350. The 6850HS’s nearest rival is the Intel Xeon E-2436 at 0.1% delta, while the 7735U sits close to the Intel Xeon 6337P. For users prioritizing raw CPU performance in multi-threaded applications, the 6850HS is the clear choice, offering an 88.2% lead in Cinebench R23 multi-core and a 16.8% lead in Geekbench multi-core.

The 7735U’s only advantages are its ECC memory support and slightly higher boost clock, which does not translate into a single benchmark win. Its lower 28 W TDP may appeal to ultra-portable designs seeking better battery life, but the performance sacrifice is substantial. The 6850HS, with its higher TDP and base clock, is better suited for performance-oriented laptops where sustained workloads matter more than power efficiency. The data shows that the 7000-series naming on the 7735U does not denote a generational improvement over the 6850HS; it is simply a lower-power variant of the same architecture with reduced performance. For any user choosing between these two, the 6850HS is the data-backed recommendation unless ECC memory support is an absolute requirement.
