AMD Ryzen 7 170 vs AMD Ryzen 7 PRO 7745 Comparison

The AMD Ryzen 7 PRO 7745 and AMD Ryzen 7 170 are both 8-core, 16-thread processors, but the benchmark data reveals a decisive performance gulf. Across every single head-to-head test, the Ryzen 7 PRO 7745 emerges victorious, with margins ranging from a substantial 23% to a staggering 238.8%. The data indicates that the PRO 7745 is in a completely different performance class, despite the Ryzen 7 170 being a capable processor in its own right.

Head-to-Head Benchmarks

The most dramatic difference appears in the `passmark_find_prime_numbers` test, where the Ryzen 7 PRO 7745 scores 166 against the Ryzen 7 170's 49, a delta of 238.8%. This test is heavily dependent on integer throughput and cache efficiency, and the PRO 7745's advantage is nothing short of overwhelming. The `passmark_physics` test shows a similarly lopsided result, with the PRO 7745 scoring 1699 versus 890, a 90.9% lead. This suggests a major advantage in real-time simulation workloads that rely on single-threaded responsiveness and complex instruction handling.

The PRO 7745 also dominates in multi-threaded workloads. In `passmark_multithread`, it scores 32733 compared to 20760, a 57.7% advantage. The `passmark_extended_instructions` test, which measures performance on specialized instruction sets like AES and AVX, shows a 61.4% lead for the PRO 7745 (29216 vs 18107). Data compression also favors the PRO 7745 heavily, with a score of 386829 versus 265920, a 45.5% margin. Encryption performance follows suit, with the PRO 7745 scoring 22821 against 16078, a 41.9% lead.

In `passmark_integer_math`, it scores 103330 versus 79738, a 29.6% lead. `passmark_floating_point_math` shows a 40.8% advantage (63332 vs 44979). The `passmark_random_string_sorting` test, which stresses memory latency and cache hierarchy, reveals a 68.2% lead for the PRO 7745 (46759 vs 27804). Finally, in `passmark_single_thread`, the PRO 7745 scores 3849 against 3128, a 23% lead that underscores its superior per-core performance. The data is unambiguous: the PRO 7745 wins all 11 head-to-head comparisons.

Where Each One Wins

The benchmark results paint a clear picture of which processor excels in which use case. The AMD Ryzen 7 PRO 7745 is the definitive winner in every measured category, making it the superior choice for any performance-critical application. Its 238.8% lead in prime number finding and 90.9% lead in physics simulations indicate exceptional strength in scientific computing and complex algorithmic tasks. The 61.4% advantage in extended instructions makes it a powerhouse for content creation, 3D rendering, and any workload that leverages modern CPU instruction sets.

The PRO 7745's 57.7% lead in multithreaded performance and 45.5% lead in data compression make it ideal for video encoding, file archiving, and server-side workloads that demand high parallel throughput. Its 41.9% advantage in encryption also positions it as the stronger option for security-sensitive tasks like VPN gateways or database encryption.

The AMD Ryzen 7 170, while not winning any head-to-head comparisons, still demonstrates respectable performance. Its scores of 20760 in multithreaded and 3128 in single-threaded tests indicate it can handle everyday productivity tasks and moderate multitasking. However, the data shows no scenario where the Ryzen 7 170 has an edge; it simply trails the PRO 7745 in every metric. For users running basic office applications, web browsing, or light coding, the Ryzen 7 170 would be adequate, but those seeking maximum performance must look to the PRO 7745.

Architecture Differences

The two processors diverge significantly at the architectural level, explaining the performance disparity. The Ryzen 7 PRO 7745 is built on the Zen 4 architecture using a 5 nm process node at TSMC, with a die size of 71 mm² and 6,570 million transistors. In contrast, the Ryzen 7 170 uses the Zen 3+ architecture on a 6 nm node, also from TSMC, but with a much larger die size of 210 mm² and no transistor count listed. The smaller, denser 5 nm node gives the PRO 7745 a fundamental efficiency and clock-speed advantage.

Cache configuration is a major differentiator. Both have 64 KB of L1 cache per core, but the PRO 7745 has 1 MB of L2 cache per core versus the Ryzen 7 170's 512 KB per core. More importantly, the PRO 7745 has 32 MB of shared L3 cache, double the Ryzen 7 170's 16 MB. This larger cache hierarchy is a primary driver of the PRO 7745's superior performance in data-heavy tests like random string sorting and prime number finding.

Clock speeds also favor the PRO 7745, with a base clock of 3.80 GHz and boost clock of 5.30 GHz, compared to the Ryzen 7 170's 3.20 GHz base and 4.75 GHz boost. The PRO 7745 carries a 65 W TDP, while the Ryzen 7 170 is more power-efficient at 35 W. The PRO 7745 uses the AMD Socket AM5 and supports PCIe Gen 5 with 24 lanes, whereas the Ryzen 7 170 uses the AMD Socket FP7 (a mobile socket) and supports PCIe Gen 4 with 20 lanes. Both support DDR5 dual-channel memory, but the PRO 7745 has a higher memory bandwidth of 83.2 GB/s versus 76.8 GB/s. The PRO 7745 also features Radeon Graphics, while the Ryzen 7 170 has the Radeon 680M iGPU.

The Verdict

The data unequivocally favors the AMD Ryzen 7 PRO 7745 for any user prioritizing raw performance. With an 88th percentile ranking among all CPUs and an average benchmark score of 43704, it edges out the Ryzen 7 170's average of 43689 by a hair, but the individual benchmark deltas tell the real story. The PRO 7745 is the only choice for demanding workloads like 3D rendering, scientific simulation, or heavy multitasking, given its massive leads in multithreaded (57.7%), physics (90.9%), and extended instruction (61.4%) tests.

The AMD Ryzen 7 170, however, is not without merit. Its 35 W TDP makes it the far more power-efficient option, suitable for thin-and-light laptops or fanless designs where thermal headroom is critical. Its 2025 release date also makes it a newer product, and its Radeon 680M integrated graphics may offer better iGPU performance for light gaming or media playback. For users who value battery life and portability over maximum compute throughput, the Ryzen 7 170 is a sensible pick. For everyone else, the benchmark results are conclusive: the Ryzen 7 PRO 7745 is the superior processor in every measurable way.
