The Verdict

The recorded data shows an unambiguous performance split between these two processors. The Ryzen 7 9850X3D wins all 15 head-to-head benchmarks in the database. The Ryzen AI 7 445 does not win a single recorded test.

The Ryzen 7 9850X3D sits at the 92nd percentile of all CPUs with an average benchmark score of 58386. Its nearest rivals include the Intel Xeon Platinum 8260M at 58323 (0.1% behind), the Intel Xeon w5-2545 at 58504 (0.2% ahead), the Intel Core i9-14900 at 58115 (0.5% behind), and the AMD Ryzen AI 9 HX 470 at 58826 (0.7% ahead). This places the desktop chip in the upper tier of processors by overall score.

The Ryzen AI 7 445 sits at the 79th percentile with an average benchmark score of 26936. Its nearest rivals are the Intel Core i7-1370P at 26900 (0.1% behind), the AMD Ryzen 5 7545U at 26849 (0.3% behind), the AMD Ryzen 7 5700G at 27051 (0.4% ahead), and the Intel Core i9-9900K at 27097 (0.6% ahead). The mobile chip competes in a lower performance band.

The data indicates the desktop part is the choice for workloads that demand maximum throughput, particularly multi-threaded rendering, physics simulation, and prime number computations where its margins are extreme. The mobile part suits power-constrained environments, with its 28 W TDP versus 120 W, but the performance gap is substantial across every recorded metric.

Head-to-Head Benchmarks

The Ryzen 7 9850X3D secures every recorded benchmark win. The largest margin appears in PassMark find prime numbers, where the desktop chip scores 435 versus 56, a 676.8% advantage. This test measures integer-heavy algorithmic work and the result indicates a massive throughput difference.

PassMark physics shows the second-largest gap: 4171 versus 976, a 327.4% lead. This test benefits heavily from the combination of more cores, higher clocks, and the large 96 MB L3 cache.

Cinebench R23 multi-core shows a 115.4% lead, with 22807 versus 10590. Cinebench R15 multi-core shows a 106.1% lead, with 3551 versus 1723. These render workloads scale with core count and clock speed, and the desktop chip has advantages in both.

PassMark extended instructions shows a 148.1% lead, with 39272 versus 15826. PassMark multithread shows a 128.1% lead, with 41318 versus 18115. PassMark data compression shows a 119.9% lead, with 474501 versus 215812. PassMark data encryption shows a 117.3% lead, with 22856 versus 10519.

PassMark integer math shows a 111.1% lead, with 123140 versus 58332. PassMark random string sorting shows a 111.9% lead, with 49764 versus 23488. PassMark floating point math shows a 108.3% lead, with 81998 versus 39362.

Single-thread margins are narrower but still decisive. Cinebench R15 single-core shows a 35% lead, with 343 versus 254. Cinebench R23 single-core shows a 23.4% lead, with 2228 versus 1806. PassMark single-thread shows a 31% lead, with 4704 versus 3591 in both recorded single-thread tests.

Where Each One Wins

The Ryzen 7 9850X3D wins every benchmark category where wins are recorded. The most extreme margins appear in prime number finding and physics, where the desktop chip's combination of 8 cores, 16 threads, 5.60 GHz boost, and 96 MB L3 cache produces results 676.8% and 327.4% higher respectively.

Multi-threaded rendering workloads show a consistent pattern. Cinebench R23 multi-core and R15 multi-core both record leads above 100%. Data compression and encryption also exceed 100% margins. Integer math, floating point math, and random string sorting all land between 108% and 112% leads. The desktop chip is the clear choice for compute-heavy tasks such as rendering, simulation, compression, and encryption.

Single-core performance favors the desktop chip but by a smaller margin. The 23.4% to 35% range across Cinebench and PassMark single-thread tests reflects the higher boost clock of 5.60 GHz versus 4.60 GHz. This matters for lightly threaded applications where the mobile chip's lower clock becomes a limiting factor.

The Ryzen AI 7 445 has no recorded benchmark wins. Its 28 W TDP and 4 MB L3 cache place it in a different performance class. The mobile chip's advantage lies in its power envelope and its support for LPDDR5X memory, which suits compact systems. But in raw performance, the data shows no category where the mobile part takes the lead.

The average benchmark scores confirm the separation: 58386 for the desktop chip versus 26936 for the mobile chip. The desktop chip ranks at the 92nd percentile of all CPUs, while the mobile chip ranks at the 79th percentile. For users whose priority is maximum performance across the recorded tests, the Ryzen 7 9850X3D is the only option supported by the data. The Ryzen AI 7 445 serves a different purpose: a low-power mobile processor where performance per watt matters more than peak throughput.
