AMD Ryzen 9 8940HX vs AMD Ryzen Embedded 9950X Comparison

Head-to-Head Benchmarks

The database contains a full benchmark profile for the AMD Ryzen 9 8940HX, while the AMD Ryzen Embedded 9950X has no recorded benchmark scores. This creates an asymmetric comparison where the 8940HX can be positioned against its nearest rivals, but the Embedded 9950X cannot be measured directly. Still, the architectural data in the database allows for a meaningful evaluation of what each processor is designed to do.

Starting with the 8940HX’s recorded results, it posts a Cinebench R23 multi-core score of 32521 and a single-core score of 1917. In Cinebench R15, it reaches 5355 multi-core and 292 single-core. PassMark results show a multi-thread score of 49731, a single-thread score of 3874, and an average benchmark score of 81103. That average places it at the 95th percentile of all CPUs in the database, meaning it outranks 95% of recorded processors.

The nearest rivals in the database are telling. The Intel Xeon w5-3535X averages 81115, which is essentially identical to the 8940HX’s 81103, a delta of 0%. The Intel Core i9-14900KS averages 81127, also a 0% delta. The AMD Ryzen AI Max+ PRO 395 comes in at 80762, putting the 8940HX ahead by 0.4%. The Intel Xeon 638 averages 80723, and the 8940HX leads by 0.5%. These are extremely tight margins, indicating that the 8940HX performs at the same level as some of the strongest desktop and workstation chips in the database, despite its mobile designation.

The Embedded 9950X has no benchmark scores recorded, so its average benchmark score is 0 and its percentile is 50, which is the database default for unmeasured parts. This is not a performance verdict, it simply means no measured data exists. Without scores, the head-to-head comparison must rely on specifications and architectural characteristics.

Where Each One Wins

For the Ryzen 9 8940HX, the wins are concrete and measurable. In multi-threaded workloads, its Cinebench R23 score of 32521 is substantial, and its PassMark multi-thread score of 49731 confirms strong parallel throughput. The 8940HX also shows high single-thread capability with a Cinebench R23 single-core score of 1917 and a PassMark single-thread score of 3874. Data compression in PassMark reaches 650984, floating point math hits 113921, and integer math reaches 189221. Extended instructions score 47802, random string sorting scores 75381, and data encryption scores 39318. Prime number finding is lower at 251, but that is a narrowly focused test. Physics processing scores 2104.

The 8940HX’s 16 cores and 32 threads, combined with a boost clock of 5.30 GHz, place it in the upper tier of mobile processors. Its 64 MB of L3 cache is identical to the Embedded 9950X, but the 8940HX uses Zen 4 architecture on a 5 nm TSMC process. That process node is one generation behind the Embedded 9950X’s 4 nm node.

The Ryzen Embedded 9950X wins on paper in several areas. Its base clock of 4.30 GHz is significantly higher than the 8940HX’s 2.40 GHz base, and its boost clock of 5.70 GHz exceeds the 8940HX’s 5.30 GHz. It uses Zen 5 architecture on a 4 nm TSMC process, which is newer than the 8940HX’s Zen 4 on 5 nm. The Embedded 9950X has 80 KB of L1 cache per core versus 64 KB per core on the 8940HX, and it supports ECC memory, which the 8940HX does not. Memory bandwidth is also higher at 89.6 GB/s versus 83.2 GB/s.

The Embedded 9950X has a TDP of 170, which is more than three times the 8940HX’s 55. That higher power envelope allows for sustained high clock speeds, but it also means the Embedded 9950X is designed for desktop or embedded systems with adequate cooling, not mobile chassis. The 8940HX’s lower TDP makes it suitable for laptops where thermal limits are tighter.

The Verdict

Based strictly on the data, the Ryzen 9 8940HX is the only one of the two with measured performance. Its 95th percentile ranking and near-identical average scores to the Intel Xeon w5-3535X and Intel Core i9-14900KS confirm that it delivers top-tier performance in a mobile form factor. Users who need a high-core-count processor in a laptop will find the 8940HX’s 16 cores, 32 threads, and 5.30 GHz boost clock sufficient for demanding multi-threaded workloads.

The Ryzen Embedded 9950X cannot be evaluated on performance because the database contains no benchmark results for it. Its architectural advantages are clear: newer Zen 5 cores, a higher boost clock of 5.70 GHz, a higher base clock of 4.30 GHz, 80 KB L1 per core, ECC memory support, and higher memory bandwidth. These specifications point to a processor designed for embedded systems that require long-term reliability and error-correcting memory. The 170 TDP suggests it is meant for systems with robust cooling, not portable devices.

For a mobile user, the 8940HX is the obvious choice because it has measured data showing it competes with desktop-class CPUs. For an embedded system designer who prioritizes ECC support, newer architecture, and higher clock speeds, the Embedded 9950X offers those features, but the lack of recorded benchmarks means performance claims cannot be verified from the database.

Architecture Differences

The two processors diverge significantly in architecture despite sharing the same core and thread count. The Ryzen 9 8940HX is built on Zen 4 architecture with the codename Dragon Range, part of the 8000 series. It uses a 5 nm process from TSMC and contains 13,140 million transistors on a die size of 2x 71 mm². The Ryzen Embedded 9950X uses Zen 5 architecture with the codename Granite Ridge, part of the 9000 series. It is fabricated on a 4 nm process from TSMC and packs 16,630 million transistors on a die size of 2x 70.6 mm².

The cache configurations are similar in L3, with both offering 64 MB, and both have 1 MB of L2 per core. The difference appears in L1 cache: the 8940HX has 64 KB per core, while the Embedded 9950X has 80 KB per core. That larger L1 cache can reduce latency for frequently accessed data.

Memory support is DDR5 for both, and both use dual-channel memory buses. The Embedded 9950X has a memory bandwidth of 89.6 GB/s, which is higher than the 8940HX’s 83.2 GB/s. ECC memory is supported only on the Embedded 9950X, a critical feature for embedded and server workloads where data integrity is paramount.

PCIe support is identical: Gen 5 with 28 lanes from the CPU. Both processors have integrated graphics, though the 8940HX uses Radeon 610M while the Embedded 9950X uses a generic Radeon Graphics solution.

The sockets differ. The 8940HX uses AMD Socket FL1, which is a mobile socket, while the Embedded 9950X uses AMD Socket AM5, a desktop and embedded socket. This reinforces their intended market segments: mobile versus desktop or embedded systems.

Both processors have unlocked multipliers, allowing overclocking. The 8940HX has a base clock of 2.40 GHz, which is low for a 16-core part, but its boost clock of 5.30 GHz compensates under load. The Embedded 9950X has a much higher base clock of 4.30 GHz, which means it maintains higher performance at idle and in lightly threaded tasks without needing to boost as aggressively.

The release dates differ by several months. The 8940HX was released on April 22, 2025, while the Embedded 9950X was released on October 6, 2025. Both are listed as active in production.

The Embedded 9950X is part of the Ryzen Embedded line, which targets industrial, edge, and server applications. Its 170 TDP and ECC support align with that purpose. The 8940HX is part of the 8000 series mobile lineup, with a 55 TDP that suits thin-and-light gaming or workstation laptops. The transistor count difference is notable: the Embedded 9950X has 16,630 million transistors versus 13,140 million on the 8940HX, reflecting the newer Zen 5 design and its additional architectural features.

In summary, the 8940HX is a mobile processor with proven benchmark results, while the Embedded 9950X is a newer, more power-hungry embedded part with architectural upgrades but no recorded performance data in the database.
