AMD Ryzen 7 8745HX vs AMD Ryzen Embedded 9700X Comparison

Head-to-Head Benchmarks

The database does not contain direct head-to-head benchmark comparisons between the AMD Ryzen 7 8745HX and the AMD Ryzen Embedded 9700X. The recorded data for the Ryzen Embedded 9700X includes no benchmark scores, which means the two processors cannot be directly compared through measured test results in this dataset. The Ryzen 7 8745HX, however, has a complete set of PassMark scores across eleven tests, and those scores provide a concrete reference point for what the mobile part delivers.

The Ryzen 7 8745HX produces an average benchmark score of 60,104. That figure places it at the 92nd percentile among all CPUs in the database. Its nearest rivals are all high-end desktop or mobile parts: the AMD Ryzen 9 7945HX sits at 60,099 with a 0% delta, the Intel Core i9-14900F scores 60,008 with a 0.2% delta, the AMD Ryzen 9 7945HX3D scores 59,641 with a 0.8% delta, and the Intel Xeon Gold 6338T scores 60,572 with a -0.8% delta. In practical terms, the 8745HX is statistically tied with the Ryzen 9 7945HX, marginally ahead of the Core i9-14900F and the 7945HX3D, and only 0.8% behind the Xeon Gold 6338T. That is a strong showing for an 8-core mobile processor.

Within its own benchmark suite, the 8745HX shows a clear split between single-thread and multi-thread performance. Its single-thread score is 3,879 in both PassMark listings. Multi-thread score is 31,517. Integer math reaches 100,328, while floating-point math sits at 61,972. Data compression scores 363,759, which is by far the highest single value in the set. Data encryption hits 21,840, extended instructions score 27,638, random string sorting scores 44,494, physics scores 1,681, and find prime numbers scores 159. These are the only benchmark numbers available for either processor in this comparison.

Where Each One Wins

Because the Ryzen Embedded 9700X has no recorded benchmark scores in the database, the only measurable wins belong to the Ryzen 7 8745HX. The 8745HX demonstrates capability across every workload category that has data: integer math, floating-point math, encryption, compression, sorting, physics, and single-thread operations. Its single-thread score of 3,879 indicates solid per-core performance for an 8-core mobile part, and its multi-thread score of 31,517 shows that the processor scales well across its 16 threads.

The Ryzen Embedded 9700X, on the other hand, cannot be assigned any benchmark-based wins from the recorded data. Its average benchmark score is listed as 0, and its percentile rank is 50, which reflects the absence of measured results rather than actual performance. The processor does carry a higher base clock of 3.80 GHz versus 3.60 GHz, a higher boost clock of 5.50 GHz versus 5.10 GHz, and a larger L1 cache of 80 KB per core versus 64 KB per core. Those specification advantages suggest the 9700X should perform well in single-threaded workloads, but the database does not confirm this with scores.

For use-case planning, the 8745HX is the only part with proven benchmark results. The data supports it for tasks that benefit from high multi-thread throughput, such as compression, integer math, and floating-point calculations. The 9700X remains an unknown quantity in this dataset, so any claims about its workload strengths cannot be backed by measured numbers.

Architecture Differences

The two processors come from different architectural generations. The Ryzen 7 8745HX uses Zen 4 with the Dragon Range codename, part of the 8000 series. The Ryzen Embedded 9700X uses Zen 5 with the Granite Ridge codename, part of the 9000 series. The 8745HX is built on a 5 nm process at TSMC, while the 9700X uses a 4 nm process at TSMC. The 9700X integrates more transistors: 8,315 million versus 6,570 million for the 8745HX. Die size is nearly identical at 70.6 mm² for the 9700X and 71 mm² for the 8745HX.

Cache configurations differ as well. The 8745HX has 64 KB of L1 per core, 1 MB of L2 per core, and 32 MB of shared L3. The 9700X has 80 KB of L1 per core, 1 MB of L2 per core, and 32 MB of shared L3. The larger L1 cache on the 9700X is consistent with the Zen 5 design, which typically expands per-core cache resources. Neither processor features 3D V-Cache, so L3 capacity is identical at 32 MB.

The 8745HX uses the AMD Socket FL1, while the 9700X uses the AMD Socket AM5. Both processors support DDR5 memory in a dual-channel configuration, but memory bandwidth differs slightly: the 8745HX lists 83.2 GB/s, the 9700X lists 89.6 GB/s. The 9700X supports ECC memory, the 8745HX does not. PCIe support also differs: the 8745HX provides Gen 5 with 28 lanes (CPU only), while the 9700X provides Gen 5 with 24 lanes (CPU only). Both processors have integrated graphics, but the 8745HX uses Radeon 610M while the 9700X lists simply Radeon Graphics. Both have unlocked multipliers, and both are listed as Active in production status.

The Verdict

The data in this comparison is one-sided because the Ryzen Embedded 9700X has no recorded benchmark scores. The Ryzen 7 8745HX, by contrast, has a full set of PassMark results and an average score of 60,104, which places it at the 92nd percentile among all CPUs. Its nearest rivals, all within a 0.8% delta, confirm that the 8745HX performs at a level comparable to high-end desktop and mobile parts like the Ryzen 9 7945HX and the Core i9-14900F.

For anyone selecting between these two processors strictly from the recorded data, the 8745HX is the only part with proven performance. It delivers strong multi-thread results, a single-thread score of 3,879, and a multithread score of 31,517. It operates at a lower TDP of 55 W, which suits mobile or power-constrained systems. Its socket is AMD Socket FL1, its integrated graphics are Radeon 610M, and it does not support ECC memory.

The Ryzen Embedded 9700X offers a higher base clock of 3.80 GHz, a higher boost clock of 5.50 GHz, a newer Zen 5 architecture on a 4 nm process, more transistors at 8,315 million, a larger L1 cache at 80 KB per core, higher memory bandwidth at 89.6 GB/s, and ECC memory support. It targets desktop systems with an AM5 socket and a 65 W TDP. But without benchmark scores, the database cannot confirm how those specifications translate into actual performance.

The choice depends on what the recorded data can support. The 8745HX is the verified performer with measurable results across multiple workload categories. The 9700X is a specification-rich part with architectural advantages on paper, but its performance remains unmeasured in this dataset. For a builder who needs confirmed benchmark data, the 8745HX is the defensible pick. For a builder who values the newer Zen 5 architecture, higher clocks, and ECC support, the 9700X offers those features, but the database provides no evidence of its real-world speed.
