AMD Ryzen 7 7745HX vs AMD Ryzen 7 PRO 6850H Comparison

The AMD Ryzen 7 7745HX and AMD Ryzen 7 PRO 6850H are both 8-core, 16-thread mobile processors, but the benchmark data reveals a decisive performance gap. The 7745HX wins all 17 head-to-head comparisons, with the largest margins in CPU-intensive workloads. This analysis breaks down the scores, architectural differences, and use cases that separate these two AMD parts.

Head-to-Head Benchmarks

The 7745HX dominates every single benchmark in the comparison, but the margin of victory varies significantly by workload type. The largest win comes in the PassMark find prime numbers test, where the 7745HX scores 156 versus 59 for the 6850H — a 164.4% advantage. This extreme gap highlights how the newer architecture excels at integer-heavy, branch-dependent calculations.

Cinebench results tell a similar story. In Cinebench R23 multi-core, the 7745HX scores 18,452.5 against 12,393 for the 6850H, a 48.9% lead. The single-core R23 result is closer but still substantial: 1,850 versus 1,480, a 25% advantage. The R15 tests show even larger relative gaps, with the 7745HX ahead by 43.2% in multi-core (2,986 vs 2,085.5) and 43.6% in single-core (294.5 vs 205.1).

Geekbench results reinforce the pattern. The 7745HX posts 13,613 in multi-core versus 9,683 for the 6850H, a 40.6% lead. Single-core Geekbench shows 2,366 against 1,716, a 37.9% advantage. These consistent double-digit leads across different benchmark suites indicate a fundamental performance tier difference rather than workload-specific optimization.

PassMark tests reveal where the gap narrows. The smallest margins come in single-thread tests: 3,947 versus 3,305, a 19.4% lead. Data encryption and integer math both show 22.9% advantages (22,967 vs 18,681 and 105,773 vs 86,068 respectively). Data compression shows a 29.8% gap (383,322 vs 295,214). Floating-point math sits at 33.2% (64,297 vs 48,276), while extended instructions reach 47.4% (28,966 vs 19,654). The 7745HX also leads in random string sorting by 42.7% (44,474 vs 31,170), multithread by 39.1% (32,581 vs 23,417), and physics by 55.3% (1,697 vs 1,093).

The averaged benchmark scores reflect this overall dominance. The 7745HX has an average benchmark score of 33,091, while the 6850H sits at 32,812. Both CPUs occupy the 83rd percentile among all CPUs, but the 7745HX sits alongside rivals like the Intel Core i7-13650HX and AMD Ryzen 7 8700G with 0% delta, while the 6850H's nearest rivals include the AMD Ryzen 5 7400F and Intel Core i5-14600T.

Architecture Differences

The two processors come from different generations and design philosophies. The 7745HX uses the Zen 4 architecture on a 5 nm TSMC process node, codenamed Dragon Range. The 6850H uses Zen 3+ on a 6 nm TSMC node, codenamed Rembrandt. The process node difference directly contributes to the 7745HX's higher clock speeds: 3.60 GHz base and 5.10 GHz boost, compared to 3.20 GHz base and 4.70 GHz boost for the 6850H.

Cache configurations differ substantially. Both have 64 KB of L1 per core, but the 7745HX has 1 MB of L2 per core versus 512 KB per core on the 6850H. The L3 cache is also doubled: 32 MB shared on the 7745HX versus 16 MB shared on the 6850H. This doubled cache capacity likely contributes to the 7745HX's superior performance in cache-sensitive workloads like prime number finding.

The 7745HX uses AMD Socket FL1, while the 6850H uses AMD Socket FP7. The 7745HX has a 55 W TDP, 10 W higher than the 6850H's 45 W. The 7745HX has an unlocked multiplier, whereas the 6850H does not. The 7745HX also has a larger die size at 71 mm² compared to 208 mm² for the 6850H, though the 7745HX's transistor count is listed at 6,570 million while the 6850H's is not provided.

Platform features also differ. The 7745HX supports PCIe Gen 5 with 28 lanes (CPU only), while the 6850H supports PCIe Gen 4 with 20 lanes. Both support DDR5 dual-channel memory, but the 7745HX has a higher memory bandwidth rating at 83.2 GB/s versus 76.8 GB/s for the 6850H. The 7745HX supports ECC memory; the 6850H does not. Integrated graphics differ as well: the 7745HX carries a Radeon 610M, while the 6850H has a Radeon 680M.

Where Each One Wins

The 7745HX wins every benchmark in this comparison, but the size of the win varies meaningfully by workload. Its largest advantages come in compute-heavy tasks: prime number finding (164.4%), physics simulation (55.3%), and extended instruction workloads (47.4%). These results suggest the 7745HX is particularly well-suited for scientific computing, financial modeling, and any application that relies on complex mathematical operations.

Content creation and rendering workloads also favor the 7745HX strongly. The 48.9% lead in Cinebench R23 multi-core and 43.2% lead in R15 multi-core indicate that video rendering, 3D modeling, and batch processing will complete noticeably faster on the 7745HX. The 40.6% Geekbench multi-core advantage reinforces this conclusion for general productivity and multitasking scenarios.

The 6850H's closest performance to the 7745HX comes in single-threaded tasks, where the gap narrows to 19.4%. This means for lightweight, single-threaded applications like web browsing, document editing, and basic office work, the performance difference is less pronounced. The 6850H also comes closest in data encryption and integer math (both 22.9%), suggesting that for everyday computing and light server duties, the older chip remains competitive.

However, the 6850H shows no workload where it beats the 7745HX. Its lower TDP of 45 W versus 55 W may make it more suitable for thinner, cooler-running laptops, but this is a thermal characteristic rather than a performance advantage. The 6850H's Radeon 680M integrated graphics may offer better iGPU performance in gaming scenarios, but no benchmark data in this comparison covers that area.

The Verdict

The data is unambiguous: the AMD Ryzen 7 7745HX is the superior processor in every measured benchmark. With a 100% win rate across 17 tests and margins ranging from 19.4% to 164.4%, it offers substantially better performance for users who need maximum CPU throughput. The 7745HX should be the choice for users running demanding workloads like video rendering, 3D modeling, scientific simulations, or heavy multitasking, where its 48.9% Cinebench R23 multi-core lead and 55.3% physics test advantage will translate directly into faster completion times.

The 6850H, while clearly slower in every test, may still serve users who prioritize lower power consumption (45 W vs 55 W TDP) or who need the Radeon 680M integrated graphics. Its closest performance to the 7745HX comes in single-threaded tasks at 19.4% behind, meaning everyday computing differences will be less noticeable. The 6850H also supports the same DDR5 memory standard and has the same 8-core, 16-thread configuration, so it remains a capable mobile processor for general productivity. However, for anyone choosing between these two based purely on computed performance, the 7745HX is the clear winner in every category measured.
