AMD Ryzen 7 9850X3D vs AMD Ryzen 7 PRO 8845HS Comparison

AMD Ryzen 7 9850X3D and AMD Ryzen 7 PRO 8845HS are both 8-core, 16-thread AMD processors, but they are built for entirely different environments. The 9850X3D is a desktop part from the 9000 series, while the PRO 8845HS is a mobile processor from the 8000 series. Benchmark data shows the desktop chip wins 12 of 15 direct comparisons, while the mobile chip takes the remaining 3, with each CPU dominating in different workload categories.

Where Each One Wins

The AMD Ryzen 7 9850X3D establishes a clear lead in the majority of recorded tests, particularly in compute-heavy and parallel workloads. Its wins span PassMark integer math, floating point math, extended instructions, data compression, data encryption, prime number finding, physics, multithread, random string sorting, and single-thread tests. The largest margins appear in prime number finding and physics, where the desktop processor outperforms the mobile chip by 400% and 200.3% respectively. These results point to a processor that handles sustained multi-threaded computation with far greater headroom.

The AMD Ryzen 7 PRO 8845HS wins in three specific areas: Cinebench R15 single-core, Cinebench R23 multi-core, and Cinebench R23 single-core. The Cinebench R23 multi-core result is notable because it is the only multi-thread benchmark where the mobile part beats the desktop part, and it does so by a significant 7.2% margin. The Cinebench R23 single-core win is even larger, with the PRO 8845HS scoring 3468 versus 2228, a 35.8% advantage. These wins suggest the mobile chip has a more efficient boost behavior in certain rendering scenarios, even if it loses in the broader PassMark suite.

Architecture Differences

The two processors come from different generations and architectures. The 9850X3D is built on Zen 5 architecture with the Granite Ridge codename, while the PRO 8845HS uses Zen 4 with the Hawk Point codename. Both are manufactured by TSMC on a 4 nm process node, but the similarities end there. The desktop chip uses AMD Socket AM5, whereas the mobile chip uses AMD Socket FP7.

Die size and transistor counts differ substantially. The 9850X3D has a die size of 70.6 mm² with 8,315 million transistors, while the PRO 8845HS has a much larger 178 mm² die with 25,000 million transistors. The larger mobile die reflects the integrated Radeon 780M graphics, which is a more capable integrated GPU than the standard Radeon Graphics found in the desktop part.

Cache configuration is another major differentiator. The 9850X3D carries 80 KB of L1 cache per core, 1 MB of L2 cache per core, and a massive 96 MB of shared L3 cache. The PRO 8845HS has 64 KB of L1 cache per core, 1 MB of L2 cache per core, but only 16 MB of shared L3 cache. That 80 MB difference in L3 cache is the primary reason the 9850X3D excels in cache-sensitive workloads like prime number finding and data compression.

Head-to-Head Benchmarks

The most striking result in the head-to-head data is the Cinebench R23 single-core test. The PRO 8845HS scores 3468 against the 9850X3D's 2228, a 35.8% lead. This is the largest single-core margin in either direction across all tests. Cinebench R15 single-core also goes to the mobile chip, but by a much smaller 1.7% margin (349 versus 343).

Multi-core rendering tells a mixed story. In Cinebench R15 multi-core, the 9850X3D wins decisively with 3551 against 2476, a 43.4% advantage. However, in Cinebench R23 multi-core, the PRO 8845HS reverses the outcome with 24565 versus 22807, a 7.2% lead. This inconsistency between two Cinebench versions is unusual and suggests the mobile chip's boost behavior favors the R23 workload specifically.

The PassMark suite shows consistent dominance for the desktop chip. The 9850X3D leads in extended instructions by 54.4% (39272 versus 25434), in floating point math by 39.1% (81998 versus 58965), in data compression by 38% (474501 versus 343952), and in integer math by 26.1% (123140 versus 97625). The passmark multithread test shows a 44.6% lead (41318 versus 28572), while the passmark single-thread test shows a 25% lead (4704 versus 3762).

The most extreme margin is in prime number finding, where the 9850X3D scores 435 against 87, a 400% difference. Physics follows at 200.3% (4171 versus 1389). Data encryption is closer but still favors the desktop part at 11.6% (22856 versus 20487). Random string sorting shows an 18.9% lead (49764 versus 41867).

Specification Differences

The two processors differ in nearly every specification field except core count, thread count, memory support, memory bus, memory bandwidth, ECC support, and production status. Both have 8 cores, 16 threads, DDR5 memory support, dual-channel memory buses, 89.6 GB/s memory bandwidth, ECC memory support, and are marked as Active in production.

Clock speeds differ significantly. The 9850X3D has a base clock of 4.70 GHz and a boost clock of 5.60 GHz, while the PRO 8845HS runs at 3.80 GHz base and 5.10 GHz boost. Thermal design power reflects the form factor difference: the desktop chip draws 120 W, the mobile chip only 45 W.

The desktop part features PCIe Gen 5 with 24 CPU lanes, while the mobile part uses PCIe Gen 4 with 20 lanes. The 9850X3D has an unlocked multiplier, the PRO 8845HS does not. The desktop chip's launch MSRP is $499, while the mobile chip has no recorded launch MSRP. Release dates also differ: the 9850X3D launched on 2026-01-28, and the PRO 8845HS launched on 2024-04-15.

The cache hierarchy shows 80 KB L1 per core on the desktop part versus 64 KB per core on the mobile part. L2 is identical at 1 MB per core. L3 is 96 MB shared versus 16 MB shared. The integrated graphics differ as well, with Radeon Graphics on the desktop part and the more capable Radeon 780M on the mobile part.

The Verdict

The benchmark data presents a clear split. The AMD Ryzen 7 9850X3D is the stronger processor for the vast majority of compute workloads, with 12 wins out of 15 head-to-head tests. Its 96 MB of L3 cache and higher clock speeds translate into dominant results in prime number finding, physics, extended instructions, and multithreaded PassMark tests. The desktop part also holds a 92nd percentile ranking against all CPUs, compared to the PRO 8845HS's 86th percentile.

The AMD Ryzen 7 PRO 8845HS is the better choice in rendering-specific scenarios. Its Cinebench R23 results are particularly strong, beating the desktop chip in both single-core and multi-core versions of that benchmark. The mobile chip also has a lower 45 W TDP, which makes it suitable for systems where power consumption is a priority. However, its 86th percentile ranking and lower scores across the PassMark suite indicate it cannot match the raw throughput of the 9850X3D in most tasks.

The 9850X3D carries a launch MSRP of $499, fits into AMD Socket AM5, and offers PCIe Gen 5 connectivity. The PRO 8845HS uses AMD Socket FP7, PCIe Gen 4, and includes the Radeon 780M integrated graphics. The data shows that users needing maximum multi-threaded performance and cache-sensitive workload acceleration should choose the 9850X3D, while those prioritizing Cinebench rendering performance and lower power draw should consider the PRO 8845HS.
