Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark comparisons between the AMD Ryzen 7 8840HX and the AMD Ryzen Embedded 9950X. The head-to-head benchmark array is empty. The 8840HX has its own recorded benchmark scores, while the Embedded 9950X has no benchmark results at all.

For the 8840HX, the recorded scores provide a performance profile. In Cinebench R23, it scores 25,265 in multi-core and 1,857 in single-core. PassMark tests show 496,427 for data compression, 29,919 for data encryption, 36,527 for extended instructions, 304 for find prime numbers, 86,747 for floating point math, 146,506 for integer math, 41,732 for multithread, 2,185 for physics, 57,971 for random string sorting, and 3,958 for single thread. Its average benchmark score is 71,797, placing it in the 94th percentile of all CPUs.

Comparing the 8840HX to its nearest rivals in the database, the Intel Core Ultra 7 265KF has an average score of 71,910, which is 0.2% higher. The Intel Xeon Platinum 8270 scores 71,370, which is 0.6% lower. The Intel Xeon 6517P scores 72,350, which is 0.8% higher, and the Intel Xeon 6724P scores 72,396, also 0.8% higher. These deltas show the 8840HX sits within a narrow band of performance around these Intel parts, slightly ahead of the Xeon Platinum 8270 and slightly behind the other three.

The Embedded 9950X has an average benchmark score of 0 and a 50th percentile ranking, indicating no measured performance data exists in the database. With no scores, no wins can be assigned to either processor in a head-to-head comparison.

Where Each One Wins

The AMD Ryzen 7 8840HX wins in any scenario where measured performance is required. The database shows its multi-core Cinebench R23 score of 25,265 and its single-core score of 1,857, along with a broad set of PassMark results covering compression, encryption, math operations, physics, and sorting. Its 94th percentile ranking and average score of 71,797 confirm it competes closely with Intel Xeon and Core Ultra parts. The 8840HX suits mobile workloads, as indicated by its market segment and its 55 W TDP. Users needing a processor for a laptop or other mobile form factor with proven benchmark data would select this part.

The AMD Ryzen Embedded 9950X wins in scenarios where platform features matter more than recorded scores. It offers 16 cores and 32 threads, a 4.30 GHz base clock, a 5.70 GHz boost clock, and a 170 W TDP. It uses the AM5 socket, which is a desktop platform, and supports ECC memory. Its memory bandwidth of 89.6 GB/s exceeds the 8840HX's 83.2 GB/s. The Embedded 9950X also uses a smaller 4 nm process node with more transistors at 16,630 million. For embedded desktop applications requiring ECC memory and the latest Zen 5 architecture, the Embedded 9950X is the only option with these attributes in the database. However, its performance remains unquantified, so any workload requiring specific benchmark validation has no data to support the Embedded 9950X.

In summary, the 8840HX wins on measured performance and mobility, while the Embedded 9950X wins on core count, clock speed, memory bandwidth, ECC support, and the desktop AM5 platform.
