Head-to-Head Benchmarks

The largest margin in the entire comparison belongs to the Ryzen 7 9850X3D in the PassMark find prime numbers test. It scores 435 against the Ryzen 9 PRO 8945HS's 91, a delta of 378 percent. This result indicates a decisive advantage in a workload that stresses integer iteration and memory latency management, likely benefiting from the larger cache architecture of the desktop part.

The PassMark physics test shows a similarly lopsided result. The Ryzen 7 9850X3D records 4171, while the Ryzen 9 PRO 8945HS manages 1430, a 191.7 percent gap. Physics simulations often depend on sustained multi-threaded throughput, and the data here shows the desktop chip delivering more than double the score.

The Cinebench R15 multicore test reinforces the pattern. The Ryzen 7 9850X3D scores 3551 versus 2536 for the Ryzen 9 PRO 8945HS, a 40 percent advantage. In the PassMark extended instructions test, the lead is 41.7 percent, with scores of 39272 and 27714 respectively. The PassMark multithread test shows a 36 percent gap, 41318 against 30378.

The Ryzen 7 9850X3D also wins the PassMark data compression test by 28.6 percent, scoring 474501 versus 368884. Floating point math shows a 29.2 percent lead, 81998 versus 63490. Integer math follows with a 19.1 percent margin, 123140 against 103390. The single-thread PassMark test shows a 20 percent advantage for the Ryzen 7 9850X3D, 4704 versus 3920, which appears twice in the recorded data under two test names. Data encryption shows a narrower 4.7 percent edge, 22856 versus 21820. Random string sorting rounds out the desktop chip's wins with an 11.4 percent margin, 49764 versus 44668.

The Ryzen 9 PRO 8945HS claims its victories in the Cinebench suite. The single-core R23 test shows its strongest result: 3552 versus 2228, a 37.3 percent lead. The single-core R15 test shows a smaller but still positive margin of 3.9 percent, 357 versus 343. The multi-core R23 test also goes to the mobile chip, with 25165 against 22807, a 9.4 percent advantage. These results indicate that the Ryzen 9 PRO 8945HS, despite its lower power envelope, can outpace the Ryzen 7 9850X3D in certain Cinebench workloads, particularly those that favor higher boost clocks under lighter loads.

Where Each One Wins

The Ryzen 7 9850X3D establishes dominance across the PassMark suite, which covers a broad range of computational tasks. Data compression, encryption, extended instructions, prime number finding, floating point math, integer math, multithreading, physics, random string sorting, and single-thread performance all favor the desktop chip. The margins range from 4.7 percent to 378 percent, with most falling between 19 and 42 percent. This spread suggests that the Ryzen 7 9850X3D does not rely on a single strength but rather delivers consistent advantages across varied instruction types and threading models.

The Ryzen 9 PRO 8945HS wins specifically in Cinebench workloads. The R23 single-core result is particularly notable, with a 37.3 percent margin that exceeds any single-core win for the Ryzen 7 9850X3D. The R23 multi-core result also favors the mobile chip, which is unexpected given its 45 W TDP against the desktop chip's 120 W TDP. The R15 single-core win, while modest at 3.9 percent, still indicates that the Ryzen 9 PRO 8945HS can hold its own in short, bursty single-threaded tasks.

The pattern suggests that the Ryzen 9 PRO 8945HS excels in workloads measured by Cinebench's rendering engine, possibly benefiting from its higher boost clock behavior in certain scenarios. The Ryzen 7 9850X3D, by contrast, shows its strength in the PassMark suite, which includes memory-intensive and arithmetic-heavy tests that may exploit its larger cache and higher sustained multi-threaded performance.

The Verdict

The data presents a clear split. The AMD Ryzen 7 9850X3D is the stronger processor in the majority of recorded benchmarks, winning 12 of 15 comparisons. Its advantages are broad, covering integer math, floating point math, compression, encryption, physics, and single-thread PassMark tests. The largest margins, 378 percent in prime number finding and 191.7 percent in physics, indicate workloads where the desktop chip delivers more than double or nearly five times the output of the mobile chip.

The AMD Ryzen 9 PRO 8945HS wins in Cinebench R23 multi-core and both single-core Cinebench tests. The R23 single-core margin of 37.3 percent is the largest single victory for either chip in any test, and the R23 multi-core win of 9.4 percent shows that the mobile part can outperform the desktop part in at least one multi-threaded rendering workload. This suggests that users running Cinebench-specific tasks may prefer the Ryzen 9 PRO 8945HS, while those running PassMark-based workloads should favor the Ryzen 7 9850X3D.

The average benchmark scores reinforce the overall picture. The Ryzen 7 9850X3D averages 58386 against the Ryzen 9 PRO 8945HS's 41963, a difference of roughly 39 percent. The percentile rankings, 92 versus 88, confirm that both chips sit in the upper tier of all CPUs, but the desktop part holds a measurable edge in aggregate performance.

Architecture Differences

The two processors use different Zen architectures. The AMD Ryzen 7 9850X3D is built on Zen 5 with the codename Granite Ridge, while the AMD Ryzen 9 PRO 8945HS uses Zen 4 with the codename Hawk Point. Both are manufactured by TSMC on a 4 nm process, but the transistor counts and die sizes differ significantly. The Ryzen 7 9850X3D contains 8,315 million transistors on a 70.6 mm² die, while the Ryzen 9 PRO 8945HS contains 25,000 million transistors on a 178 mm² die. The mobile chip packs more transistors into a larger die, likely due to its integrated Radeon 780M graphics and other mobile-specific components.

Cache configurations diverge sharply. The Ryzen 7 9850X3D has 80 KB of L1 cache per core, 1 MB of L2 per core, and 96 MB of shared L3 cache. The Ryzen 9 PRO 8945HS has 64 KB of L1 per core, 1 MB of L2 per core, and only 16 MB of shared L3 cache. The desktop chip's 96 MB L3 is six times larger, which likely contributes to its strong PassMark results in memory-sensitive tests like prime number finding and physics.

The integrated graphics differ as well. The Ryzen 7 9850X3D lists Radeon Graphics without a specific model name, while the Ryzen 9 PRO 8945HS specifies Radeon 780M. The mobile chip's integrated GPU is explicitly named, suggesting a more prominent role for graphics in its design.

Specification Differences

The AMD Ryzen 7 9850X3D uses AMD Socket AM5, while the AMD Ryzen 9 PRO 8945HS uses AMD Socket FP7. This reflects their market segments: desktop versus mobile.
