AMD Ryzen 5 PRO 8645HS vs AMD Ryzen Embedded 9700X Comparison

Where Each One Wins

The AMD Ryzen 5 PRO 8645HS and the AMD Ryzen Embedded 9700X occupy different corners of the processor landscape, and the recorded data reflects that split clearly. The Ryzen 5 PRO 8645HS is a mobile part with a full suite of benchmark results, while the Ryzen Embedded 9700X has no recorded benchmark scores in the database. This means all measurable wins, on paper, belong to the Ryzen 5 PRO 8645HS, but the comparison is more nuanced than a simple score tally.

The Ryzen 5 PRO 8645HS wins every benchmark category where data exists, because the Ryzen Embedded 9700X has an empty benchmark array. The mobile chip posts a Cinebench R23 multi-core score of 19742 and a single-core score of 2787. It also records a Passmark multi-thread score of 23569 and a single-thread score of 3858. These are the only concrete performance figures available for either processor.

The Ryzen Embedded 9700X, on the other hand, has no verified results. Its average benchmark score sits at 0, and its percentile rank among all CPUs is 50, a placeholder value that carries no performance meaning without actual tests. The database cannot confirm any workload advantage for the embedded part, even though its specifications suggest it should be competitive in multi-threaded scenarios.

The wins distribution is therefore lopsided: the Ryzen 5 PRO 8645HS records 8 wins across the measured categories, while the Ryzen Embedded 9700X records 0. This is not a statement about theoretical capability. It is a statement about available evidence. The mobile processor has been tested across Cinebench R15, R20, R23, and the full Passmark suite, covering compression, encryption, extended instructions, prime number finding, floating point math, integer math, physics, random string sorting, and single-thread workloads. The embedded processor has no such coverage.

Architecture Differences

The two chips share a common foundry and process node but diverge in nearly every other architectural detail. Both use TSMC's 4 nm process, and both support DDR5 memory with dual-channel buses and 89.6 GB/s of memory bandwidth. Both also support ECC memory, which matters for embedded and workstation deployments.

The core counts differ substantially. The Ryzen 5 PRO 8645HS uses 6 cores and 12 threads, based on the Zen 4 architecture with the Hawk Point codename. The Ryzen Embedded 9700X uses 8 cores and 16 threads, based on Zen 5 with the Granite Ridge codename. The embedded part belongs to the 9000 series and the Ryzen Embedded product line, while the mobile part belongs to the 8000 series and the Ryzen 5 PRO family.

Clock speeds tell a mixed story. The Ryzen 5 PRO 8645HS has a base clock of 4.30 GHz and a boost clock of 5.00 GHz. The Ryzen Embedded 9700X has a lower base clock of 3.80 GHz but a higher boost clock of 5.50 GHz. The mobile chip runs at a 45 W TDP, while the embedded chip runs at 65 W. Neither processor has a recorded launch MSRP in the database.

Cache hierarchies differ in size and organization. The Ryzen 5 PRO 8645HS provides 64 KB of L1 per core, 1 MB of L2 per core, and 16 MB of shared L3 cache. The Ryzen Embedded 9700X provides 80 KB of L1 per core, 1 MB of L2 per core, and 32 MB of shared L3 cache. The embedded part doubles the L3 capacity, which can benefit workloads with large working sets.

Transistor counts and die sizes are dramatically different. The Ryzen 5 PRO 8645HS integrates 25,000 million transistors on a 178 mm² die. The Ryzen Embedded 9700X integrates 8,315 million transistors on a 70.6 mm² die. This is a notable inversion: the mobile chip has roughly three times the transistor count and more than twice the die area, despite using the same process node. The chiplet design of the Zen 5 Granite Ridge part likely explains the smaller monolithic die measurement.

Connectivity also differs. The Ryzen 5 PRO 8645HS uses AMD Socket FP7 and provides PCIe Gen 4 with 20 lanes from the CPU. The Ryzen Embedded 9700X uses AMD Socket AM5 and provides PCIe Gen 5 with 24 lanes from the CPU. The embedded part offers a newer PCIe generation and more lanes, which suits expansion-heavy embedded boards.

Integrated graphics differ as well. The Ryzen 5 PRO 8645HS carries a Radeon 760M, while the Ryzen Embedded 9700X carries a generic Radeon Graphics solution. The mobile part also has a locked multiplier, whereas the embedded part has an unlocked multiplier, allowing overclocking on AM5 platforms.

The release timeline is separated by roughly a year and a half. The Ryzen 5 PRO 8645HS launched on 2024-04-15, and the Ryzen Embedded 9700X launched on 2025-10-06. Both are listed as active production parts. The mobile chip has two part numbers, 100-000001315 for FP7r2 and 100-000001388 for FP7, while the embedded chip has a single part number, 100-000001404E.

The market segments are equally distinct: the Ryzen 5 PRO 8645HS is a mobile processor, and the Ryzen Embedded 9700X is a desktop-class embedded processor. The socket difference alone prevents any direct platform interchange.

The Verdict

The data supports a straightforward conclusion for buyers who need measured performance today: the Ryzen 5 PRO 8645HS is the only one of the two with verified benchmark results. Its average benchmark score is 30879, placing it in the 82nd percentile of all CPUs in the database. That is a meaningful position. It sits within 0.4% of the AMD Ryzen 7 8700F, 0.5% ahead of the Intel Core i7-13700TE, 0.6% ahead of the AMD Ryzen 9 8945HS, and 0.6% ahead of the Intel Core i7-12700F. The mobile chip is effectively trading blows with a wide range of desktop and high-end mobile parts, despite its 45 W TDP.

The Ryzen Embedded 9700X cannot be evaluated on the same basis. Its average benchmark score is 0, its percentile is 50, and it has no nearest rivals in the database. This is not a condemnation of the hardware. It is an absence of evidence. The specifications suggest a capable processor: 8 Zen 5 cores, 16 threads, a 5.50 GHz boost clock, 32 MB of L3 cache, PCIe Gen 5, and an unlocked multiplier. But none of those specifications have been validated by recorded tests.

For a system builder choosing between the two, the decision rests on workload and platform requirements. The Ryzen 5 PRO 8645HS is the tested option with a known performance envelope, and it arrives in a mobile form factor with integrated Radeon 760M graphics. The Ryzen Embedded 9700X is the untested option with a more modern architecture, more cores, more cache, and a desktop socket, but no recorded scores to confirm its real-world behavior.

The database cannot confirm that the Ryzen Embedded 9700X outperforms the Ryzen 5 PRO 8645HS in any workload. The Zen 5 architecture and higher core count imply an advantage in multi-threaded tasks, and the higher boost clock implies an advantage in lightly threaded tasks, but these remain implications rather than measurements. Buyers who require verified performance data should treat the Ryzen 5 PRO 8645HS as the safer choice. Buyers who value the embedded part's architectural features and are willing to accept unverified performance should consider the Ryzen Embedded 9700X on its platform merits.

Head-to-Head Benchmarks

There are no head-to-head benchmark records in the database for this pair, so the comparison must rely on the Ryzen 5 PRO 8645HS's standalone results and the architectural specifications of the Ryzen Embedded 9700X.

The biggest measured wins for the Ryzen 5 PRO 8645HS are its CPU stress and compute scores. In Cinebench R23, it records a multi-core score of 19742 and a single-core score of 2787. In Cinebench R20, the multi-core score is 8291 and the single-core score is 1170. In Cinebench R15, the multi-core score is 1989 and the single-core score is 280. These numbers establish a consistent performance baseline across three generations of the Cinebench test.

The Passmark suite adds workload-specific detail. The Ryzen 5 PRO 8645HS scores 265826 in data compression, 17387 in data encryption, 21212 in extended instructions, 73 in find prime numbers, 45481 in floating point math, 72740 in integer math, 23569 in multithread, 1208 in physics, 35472 in random string sorting, and 3858 in single-thread. The multithread and single-thread scores align with the Cinebench results, showing a processor that is balanced between single-thread responsiveness and multi-thread throughput.

Relative to its nearest rivals, the Ryzen 5 PRO 8645HS is tightly clustered. The AMD Ryzen 7 8700F averages 30746, which is 0.4% below the mobile chip. The Intel Core i7-13700TE averages 31028, which is 0.5% above. The AMD Ryzen 9 8945HS averages 31074, which is 0.6% above. The Intel Core i7-12700F averages 31081, which is 0.6% above. The differences are small enough to be within normal run-to-run variation, which means the Ryzen 5 PRO 8645HS is competitive with a much higher tier of processors than its 6-core, 45 W mobile designation would suggest.

The Ryzen Embedded 9700X has no corresponding numbers. Its 8 Zen 5 cores, 16 threads, 3.80 GHz base clock, 5.50 GHz boost clock, and 32 MB of L3 cache are the only performance-relevant facts in the database. The 65 W TDP and unlocked multiplier indicate a part designed for sustained operation and tuning, but the absence of benchmark data prevents any quantitative comparison.

The closest the database comes to a head-to-head is the percentile ranking. The Ryzen 5 PRO 8645HS sits in the 82nd percentile of all CPUs, while the Ryzen Embedded 9700X sits in the 50th percentile. That gap is entirely an artifact of missing data for the embedded part, not evidence of inferior performance. A processor without test results cannot earn a meaningful percentile.

For users who rely on the database for purchasing decisions, the takeaway is that the Ryzen 5 PRO 8645HS delivers verified performance in the upper tier of all CPUs, while the Ryzen Embedded 9700X remains an unmeasured quantity with promising specifications. The mobile chip's 19742 Cinebench R23 multi-core score and 2787 single-core score are the concrete numbers to cite. The embedded chip's boost clock of 5.50 GHz and 32 MB of L3 cache are the concrete specifications to weigh. Everything else is inference.
