AMD Ryzen 9 PRO 8945HS vs AMD Ryzen Embedded 9900X Comparison

The Verdict

The database presents a clear performance hierarchy between these two AMD processors, but it is complicated by an incomplete benchmark record for one of them. The AMD Ryzen 9 PRO 8945HS is a fully measured mobile processor with a substantial dataset, while the AMD Ryzen Embedded 9900X currently has no recorded benchmark scores in the database. This means the comparison is asymmetric: we can analyze the Ryzen 9 PRO 8945HS in detail against its nearest rivals, but for the Ryzen Embedded 9900X, we can only examine its architectural specifications and compute expected outcomes from the available data.

For users strictly relying on measured performance, the Ryzen 9 PRO 8945HS is the only chip with verifiable results. It sits at the 88th percentile of all CPUs in the database, with an average benchmark score of 41,963. Its nearest rivals are tightly clustered: the Intel Core i7-14700T trails by 0.1%, the AMD Ryzen 5 7400 leads by 0.2%, and the Intel Core i7-12850HX trails by 0.4%. This means the Ryzen 9 PRO 8945HS is essentially in a statistical tie with these competitors, delivering comparable multi-core and single-core performance within a 1% band.

The Ryzen Embedded 9900X, by contrast, has no measured scores, a 50th percentile ranking, and zero average benchmark score. It is a desktop-class part with a 12-core, 24-thread configuration, a 4.40 GHz base clock, a 5.60 GHz boost clock, and a 120 W TDP. The specification sheet strongly suggests it should outperform the Ryzen 9 PRO 8945HS in multi-threaded workloads due to its 50% more cores and 50% more threads, but the database does not yet confirm this with numbers. The Ryzen Embedded 9900X also has a larger 64 MB L3 cache versus the Ryzen 9 PRO 8945HS's 16 MB, which further points to superior multi-core potential.

The verdict, based strictly on data availability, is that the Ryzen 9 PRO 8945HS is the validated performer for mobile workloads, while the Ryzen Embedded 9900X is an unmeasured but architecturally superior desktop part. Users needing immediate, confirmed benchmark results should choose the Ryzen 9 PRO 8945HS.
