AMD Ryzen 7 7745HX vs AMD Ryzen 9 PRO 6950H Comparison

The AMD Ryzen 7 7745HX decisively outperforms the AMD Ryzen 9 PRO 6950H across every single benchmark in the comparison data. In 17 head-to-head tests, the 7745HX wins all 17, with no wins recorded for the 6950H. The data shows a generational leap, not a marginal one, with the 7745HX delivering double-digit percentage advantages in nearly every workload category.

Head-to-Head Benchmarks

The most significant victories for the AMD Ryzen 7 7745HX come in multi-threaded and compute-heavy tasks. In Geekbench multicore, the 7745HX scores 13613 versus 9571 for the 6950H, a 29.7% advantage. Cinebench R23 multicore shows a similar story: 18452.5 against 13501, a 26.8% lead. These results indicate that the 7745HX is substantially faster for rendering, compilation, and any workload that scales across all 8 cores and 16 threads.

The gap narrows somewhat in single-threaded performance, but the 7745HX still holds a clear lead. In Cinebench R23 single-core, the 7745HX scores 1850 versus 1615 for the 6950H, a 12.7% difference. Geekbench single-core shows 2366 against 1996, a 15.6% margin. This consistency is notable: the 7745HX is faster not just in parallel tasks but also in latency-sensitive, single-threaded applications.

Certain workloads amplify the 7745HX’s advantage even further. The PassMark find prime numbers test is a stark example, with the 7745HX scoring 156 against just 62 for the 6950H, a massive 60.3% delta. This suggests a major improvement in integer and cryptographic-style computation. Similarly, PassMark physics shows a 34.3% lead (1697 vs 1115), and random string sorting shows a 30.6% lead (44474 vs 30859). These results point to architectural efficiency gains beyond just clock speed.

The 7745HX also dominates in more common productivity metrics. PassMark multithread scores 32581 versus 23770, a 27% lead. Data compression is 383322 against 297936, a 22.3% advantage. Even in data encryption, a task often bound by memory and instruction throughput, the 7745HX leads by 18.7% (22967 vs 18673). The smallest deltas are still significant: Cinebench R15 single-core shows an 11.7% lead for the 7745HX, and PassMark single-thread shows a 15.7% lead. There is no test in the data where the Ryzen 9 PRO 6950H comes out ahead.

Q: Which processor has a higher boost clock?

A: The Ryzen 7 7745HX has a boost clock of 5.10 GHz, while the Ryzen 9 PRO 6950H boosts to 4.90 GHz.

Architecture Differences

The two processors are built on different architectures and process nodes. The AMD Ryzen 9 PRO 6950H uses the Zen 3+ architecture, codenamed Rembrandt, fabricated on a 6 nm process at TSMC. In contrast, the AMD Ryzen 7 7745HX uses the newer Zen 4 architecture, codenamed Dragon Range, fabricated on a 5 nm process at the same foundry. This process shrink is a key factor in the 7745HX’s efficiency and higher clock speeds.

Cache configuration differs significantly. Both have 64 KB of L1 cache per core, but the L2 cache is larger on the 7745HX at 1 MB per core, versus 512 KB per core on the 6950H. The L3 cache is also doubled: the 7745HX has 32 MB shared, while the 6950H has 16 MB shared. This larger cache hierarchy explains the significant performance lead in data-heavy workloads like compression and encryption.

The transistor count and die size reflect the architectural shift. The 7745HX packs 6,570 million transistors on a 71 mm² die. The 6950H has a larger die at 208 mm², though its transistor count is not listed. The smaller die and newer process of the 7745HX enable higher clock speeds and better performance per watt, despite a higher TDP.

Memory bandwidth also favors the 7745HX. Both support dual-channel DDR5, but the 7745HX has a memory bandwidth of 83.2 GB/s versus 76.8 GB/s for the 6950H. PCIe support is another differentiator: the 7745HX offers Gen 5 with 28 lanes, while the 6950H is limited to Gen 4 with 20 lanes.

Specification Differences

The core and thread counts are identical (8 cores, 16 threads), but nearly every other specification differs. Base clock is higher on the 7745HX at 3.60 GHz versus 3.30 GHz. Boost clock is also higher on the 7745HX at 5.10 GHz versus 4.90 GHz. The 7745HX has a higher TDP at 55 watts, compared to 45 watts for the 6950H.

The sockets are different: the 6950H uses AMD Socket FP7, while the 7745HX uses AMD Socket FL1. The integrated graphics differ, with the 6950H featuring a Radeon 680M and the 7745HX featuring a Radeon 610M. ECC memory support is only present on the 7745HX. The 7745HX also has an unlocked multiplier, while the 6950H is locked. Release dates differ by about nine months, with the 6950H released in April 2022 and the 7745HX in January 2023.

Where Each One Wins

The AMD Ryzen 7 7745HX wins every benchmark category in the data. Its strongest showings are in pure compute throughput, particularly in the PassMark tests for prime numbers, physics, and random string sorting, where it leads by 30% to 60%. This makes it the clear choice for users who run heavily threaded workloads such as video rendering, 3D simulation, or scientific computation. The larger cache and newer Zen 4 architecture also give it a decisive edge in data compression and encryption tasks, suggesting faster performance in database operations and file archiving.

The AMD Ryzen 9 PRO 6950H does not win a single head-to-head benchmark. However, its lower TDP of 45 watts versus 55 watts for the 7745HX suggests it may be more power-efficient in sustained workloads, though the data does not include efficiency benchmarks. Its integrated Radeon 680M graphics are a more capable iGPU than the Radeon 610M in the 7745HX, which could matter for light gaming or media tasks without a discrete GPU. The 6950H also has a higher average benchmark score of 33201 versus 33091, but this is within a 0.3% margin and does not reflect any individual test victory.

The Verdict

The data is unambiguous: the AMD Ryzen 7 7745HX is the superior processor for performance. It wins 17 out of 17 head-to-head benchmarks, with deltas ranging from 11.7% in Cinebench R15 single-core to 60.3% in PassMark find prime numbers. Buyers seeking maximum compute performance in a mobile platform should choose the 7745HX. Its higher boost clock, doubled L2 and L3 cache, newer Zen 4 architecture, and wider PCIe Gen 5 support all contribute to its dominance.

The AMD Ryzen 9 PRO 6950H is not a competitive choice on raw benchmarks, but it is not without purpose. Its lower TDP and more powerful integrated graphics make it a better fit for thin-and-light laptops where battery life and GPU performance matter more than CPU throughput. For users who prioritize the iGPU over CPU compute, or who need a 45-watt part for thermal constraints, the 6950H remains a viable option. However, for any workload where processing power is the priority, the Ryzen 7 7745HX is the definitive winner. The 0.3% average score difference in the 6950H’s favor is statistically negligible and does not translate to a single benchmark win.
