The Verdict

The data points to a clear segmentation. The AMD Ryzen 5 7500X3D is a desktop part, released on 2025-11-11, with a launch MSRP of $269. It delivers substantially higher multi-threaded throughput and dominates computational workloads. The AMD Ryzen 5 PRO 8640HS, released on 2024-04-15, is a mobile processor designed for a different envelope. It carries a 28 W TDP versus the 7500X3D's 65 W TDP, and it wins only in single-thread tasks.

For users building a desktop system on AMD Socket AM5, the 7500X3D is the stronger performer across nearly the entire benchmark suite. Its average score of 44,573 places it in the 89th percentile, and it leads the 8640HS by 56.5% in average score. The mobile chip, in the 80th percentile, is competitive in single-thread work but falls behind in every other measured category.

For laptop or compact mobile systems using AMD Socket FP7, the 8640HS is the only relevant choice from this pair. Its 4.90 GHz boost clock and integrated Radeon 760M graphics suit a portable machine. The 7500X3D, with a 4.50 GHz boost clock and Radeon Graphics, is not designed for that socket or power class.

The verdict from the recorded data: the 7500X3D is the compute leader, but the 8640HS is the only viable option for mobile deployments. Neither chip is unlocked for overclocking, and both use 6 cores and 12 threads.

Head-to-Head Benchmarks

The 7500X3D wins 9 of the 11 shared benchmark tests, and the margins are often large. The largest single gap appears in passmark_find_prime_numbers: 221 versus 71, a 211.3% advantage. This test measures prime number generation, and the desktop chip's 96 MB shared L3 cache likely explains the dramatic difference.

Passmark_physics shows a similarly lopsided result. The 7500X3D scores 2,779, while the 8640HS scores 1,043, a 166.4% lead. Physics simulations often rely on cache hierarchy and memory latency, areas where the desktop part's larger L3 cache and higher TDP allow more sustained throughput.

Passmark_multithread gives the 7500X3D a 16.7% edge, with scores of 25,047 versus 21,465. This is a more moderate gap, reflecting that both chips have identical core and thread counts. The desktop chip's advantage here comes from its higher base clock of 4.00 GHz versus 3.50 GHz, plus the larger cache.

In passmark_extended_instructions, the 7500X3D leads by 10.5% (20,455 versus 18,507). Passmark_data_compression shows a 10.2% gap (271,649 versus 246,446). Passmark_random_string_sorting is 9.1% in favor of the desktop part (32,999 versus 30,235). Passmark_data_encryption shows a 5.6% edge (15,797 versus 14,962).

The narrowest desktop wins are in passmark_floating_point_math and passmark_integer_math, both at 1.3% (43,594 versus 43,019, and 70,774 versus 69,839, respectively). These are near-parity results, suggesting that raw arithmetic throughput is similar across the two chips.

The 8640HS takes both single-thread tests with identical margins. Passmark_single_thread and passmark_singlethread both show 3,561 versus 3,494, a 1.9% advantage. This aligns with the mobile chip's higher boost clock of 4.90 GHz versus 4.50 GHz.

Specification Differences

The two processors differ in several key specifications. The 7500X3D has a base clock of 4.00 GHz and a boost clock of 4.50 GHz. The 8640HS has a lower base clock of 3.50 GHz but a higher boost clock of 4.90 GHz.

TDP is a major divergence: the 7500X3D runs at 65 W, while the 8640HS runs at 28 W. The desktop chip uses AMD Socket AM5, and the mobile chip uses AMD Socket FP7.

Memory bandwidth differs slightly. The 7500X3D records 83.2 GB/s, while the 8640HS records 89.6 GB/s, both with dual-channel DDR5 support. Both support ECC memory.

PCIe connectivity differs significantly. The 7500X3D offers Gen 5 with 24 lanes (CPU only). The 8640HS offers Gen 4 with 20 lanes (CPU only).

Integrated graphics differ in name: the 7500X3D lists Radeon Graphics, while the 8640HS lists Radeon 760M. Both are active production parts. The 7500X3D has a launch MSRP of $269; the 8640HS has no recorded launch MSRP.

Architecture Differences

Both chips are built on Zen 4 architecture, but they are not identical designs. The 7500X3D uses the Raphael codename, from the 7000 series, and is manufactured on a 5 nm process by TSMC. It contains 11,270 million transistors on a 71 mm² die.

The 8640HS uses the Hawk Point codename, from the 8000 series, and is manufactured on a 4 nm process, also by TSMC. It contains 25,000 million transistors on a 178 mm² die. The transistor count is more than double, and the die is more than twice as large, reflecting the integrated Radeon 760M graphics and other mobile-specific components.

Cache configurations diverge sharply. Both have 64 KB of L1 per core and 1 MB of L2 per core. The L3 cache is the differentiator: the 7500X3D has 96 MB shared, while the 8640HS has 16 MB shared. This 80 MB difference is the most significant architectural gap and explains the desktop chip's dominance in cache-sensitive workloads like prime number generation and physics.

The 7500X3D is a desktop market segment part with a release date of 2025-11-11. The 8640HS is a mobile market segment part with a release date of 2024-04-15. The desktop part's generation is listed as "Ryzen 5 (Zen 4 (Raphael))", and the mobile part's generation is "Ryzen 5 (Zen 4 (Hawk Point))". Neither chip has an unlocked multiplier.

Where Each One Wins

The 7500X3D wins in every multi-threaded and compute-heavy workload recorded. The data shows a 211.3% advantage in passmark_find_prime_numbers, a 166.4% advantage in passmark_physics, and a 16.7% advantage in passmark_multithread. It also leads in data compression by 10.2%, extended instructions by 10.5%, random string sorting by 9.1%, and data encryption by 5.6%. Its wins in floating-point and integer math are narrow at 1.3% each, but they are still wins.

The 8640HS wins only in single-thread tests, with a 1.9% margin in both passmark_single_thread and passmark_singlethread. This is consistent with its higher boost clock of 4.90 GHz, which gives it a slight edge in lightly threaded, latency-sensitive tasks. It also records a higher memory bandwidth of 89.6 GB/s versus 83.2 GB/s, which may help in memory-bound single-thread scenarios.

For use-case segmentation, the 7500X3D is the stronger choice for desktop workloads involving physics simulation, prime number computation, data compression, encryption, and general multi-threaded processing. Its 96 MB L3 cache and 65 W TDP make it suitable for sustained compute tasks.

The 8640HS is the appropriate choice for mobile systems where power consumption matters. Its 28 W TDP and integrated Radeon 760M graphics make it suitable for laptops. Its single-thread advantage means it handles lightly threaded applications with slightly better responsiveness, but its 16 MB L3 cache limits performance in cache-heavy workloads.

The benchmark results leave little ambiguity: the desktop chip wins 9 of 11 tests, and the mobile chip wins 2, both by small margins. The architectural differences, particularly the L3 cache and TDP, explain the distribution of wins.
