The closest competitor, the Ryzen 7 PRO 8840HS, trails by only 0.7%, while the Intel Core i7-13700F sits 0.8% behind. The EPYC 4245P is effectively tied at 0.3% below, and the Ryzen AI 7 450 leads by a razor-thin 0.4%.

For the Ryzen Embedded 9900X, the database records a 50th percentile rank and an average benchmark score of zero, with no nearest rivals listed. That percentile figure likely reflects the absence of measured scores rather than a true performance tier. Without benchmarks, any comparison of wins or losses between the two chips is impossible from the data.

The Verdict

The data supports a clear distinction: the AMD Ryzen 7 PRO 8845HS is a measured, mid-range mobile processor with a verified performance footprint, while the AMD Ryzen Embedded 9900X is a higher-core-count desktop part with no recorded benchmarks. A user selecting between these two should base the decision on the available specifications and the intended form factor, since performance numbers exist for only one side.

The 8845HS shows an 86th percentile ranking, which places it above the median CPU in the database. Its 39,325 average benchmark score puts it in line with the EPYC 4245P, Ryzen AI 7 450, Ryzen 7 PRO 8840HS, and Core i7-13700F, all within a 1.1% spread. This indicates that the 8845HS delivers competitive multi-threaded and single-threaded results for its class, with the Cinebench R23 multi-core score of 24,565 and single-core score of 3,468 serving as strong reference points.

The 9900X, by contrast, offers 12 cores and 24 threads with a higher 4.40 GHz base clock and 5.60 GHz boost clock, but the database has no measurements to confirm how that translates into real-world performance. Its 50th percentile rank is not a performance verdict; it reflects missing data. The 9900X targets the embedded desktop segment, uses Socket AM5, and supports PCIe Gen 5 with 24 lanes, making it a different class of hardware for different deployment scenarios.

From the data alone, the 8845HS is the only one with a demonstrated benchmark record. The 9900X presents a specification advantage on paper, but no recorded scores exist to validate it. A builder who needs verified performance from the database should favor the 8845HS. A builder evaluating the 9900X must rely solely on its listed specifications, since no measurements are available.

Architecture Differences

The two processors come from different AMD generations and codenames. The Ryzen 7 PRO 8845HS belongs to the 8000 series, uses the Zen 4 architecture, and carries the Hawk Point codename. Its generation is listed as Ryzen 7 (Zen 4 (Hawk Point)). The Ryzen Embedded 9900X belongs to the 9000 series, uses the Granite Ridge codename, and its generation is listed as Ryzen Embedded (Zen 5 (Granite Ridge)). The architecture field for the 9900X is recorded as null, but the generation field clearly specifies Zen 5.

Both processors are built on a 4 nm process node at TSMC. However, the transistor counts and die sizes differ significantly. The 8845HS has 25,000 million transistors on a single 178 mm² die. The 9900X has 16,630 million transistors across 2x 70.6 mm² dies, indicating a chiplet design rather than a monolithic one. That difference in physical structure aligns with their different market segments: the 8845HS is a mobile part, while the 9900X is an embedded desktop processor.

Cache hierarchies also diverge. The 8845HS provides 64 KB of L1 per core, 1 MB of L2 per core, and 16 MB of shared L3 cache. The 9900X doubles the L1 to 80 KB per core, keeps 1 MB of L2 per core, and expands the shared L3 cache to 64 MB. That larger L3 pool on the 9900X is a substantial architectural advantage for workloads that benefit from a large shared cache, though no benchmark data confirms its impact.

Neither processor uses 3D V-Cache, as the vCache3d field is null for both. Both support DDR5 memory and dual-channel buses with an identical memory bandwidth of 89.6 GB/s. ECC memory support is present on both. The integrated graphics differ: the 8845HS uses Radeon 780M, while the 9900X uses a generic Radeon Graphics solution. The PCIe interface also differs, with the 8845HS offering Gen 4 with 20 CPU lanes and the 9900X offering Gen 5 with 24 CPU lanes.

Specification Differences

The core and thread counts are the most obvious split. The 8845HS has 8 cores and 16 threads, while the 9900X has 12 cores and 24 threads. Clock speeds favor the 9900X with a 4.40 GHz base and 5.60 GHz boost, compared to the 8845HS at 3.80 GHz base and 5.10 GHz boost. The TDP reflects their form factors: the mobile 8845HS runs at 45 watts, while the embedded desktop 9900X draws 120 watts.

Sockets differ as well. The 8845HS uses AMD Socket FP7, while the 9900X uses AMD Socket AM5. The multiplier is locked on the 8845HS and unlocked on the 9900X, meaning the embedded part allows overclocking while the mobile part does not. The market segments are listed as Mobile for the 8845HS and Desktop for the 9900X.

Release dates are separated by about 18 months. The 8845HS launched on April 15, 2024, while the 9900X launched on October 6, 2025. Both are currently marked as Active in production status. Part numbers differ: the 8845HS lists 100-000001316 (FP7r2) and 100-000001387 (FP7), while the 9900X lists 100-000000662E. Neither processor has a recorded launch MSRP in the database.

The cache difference is significant: the 8845HS has 16 MB of shared L3, while the 9900X has 64 MB. Per-core L1 also differs, with 64 KB versus 80 KB. L2 cache is identical at 1 MB per core. The 9900X uses two dies totaling 141.2 mm², while the 8845HS is a single 178 mm² die.
