AMD Ryzen 5 PRO 8645HS vs Intel Arc G3 Comparison

Head-to-Head Benchmarks

The recorded database contains no direct head-to-head benchmark entries for the AMD Ryzen 5 PRO 8645HS and the Intel Arc G3. The head-to-head comparison table is empty, and neither processor logs a win in shared tests. This absence of common benchmark data means a direct performance comparison cannot be derived from simultaneous testing.

What can be established from the database is the individual measurement profile of the AMD Ryzen 5 PRO 8645HS, which carries 17 recorded benchmark scores. The Intel Arc G3 has no benchmark entries at all, leaving its performance unquantified in the database.

The AMD part posts a Cinebench R23 multicore score of 19742 and a single-core score of 2787. In Cinebench R20, it records 8291 multicore and 1170 single-core. Cinebench R15 results stand at 1989 multicore and 280 single-core. PassMark results include a multithread score of 23569, a single-thread score of 3858, integer math at 72740, floating point math at 45481, extended instructions at 21212, data compression at 265826, data encryption at 17387, physics at 1208, random string sorting at 35472, and find prime numbers at 73.

The average benchmark score for the Ryzen 5 PRO 8645HS is 30879, placing it at the 82nd percentile among all CPUs in the database. Its nearest rivals are tightly clustered: the AMD Ryzen 7 8700F averages 30746 (0.4% lower), the Intel Core i7-13700TE averages 31028 (0.5% higher), the AMD Ryzen 9 8945HS averages 31074 (0.6% higher), and the Intel Core i7-12700F averages 31081 (0.6% higher). These margins are narrow, indicating the Ryzen 5 PRO 8645HS sits within a performance band of roughly one percent of these four processors.

The Intel Arc G3 shows a 50th percentile ranking and an average benchmark score of zero, reflecting the lack of recorded measurements. No nearest rivals are listed for it. Without benchmark data, no statistical comparison can be made between the two processors on performance grounds.

The Verdict

The data supports a clear division of roles. The AMD Ryzen 5 PRO 8645HS is the only one of the two with measured performance in the database. Its 82nd percentile ranking and average score of 30879 place it in the upper tier of CPUs, with its nearest rivals all within 0.6% of its average score. Anyone selecting between these two on the basis of recorded benchmark evidence will find that only the AMD part has any.

The Intel Arc G3 has no benchmark scores, no nearest rivals, and an average score of zero. Its 50th percentile ranking is derived from no measurements. This makes a performance-based selection impossible for the Intel part.

The Ryzen 5 PRO 8645HS should be chosen where measured compute performance matters. It delivers documented multi-threaded and single-threaded scores across Cinebench and PassMark tests. The Intel Arc G3 cannot be evaluated on the same terms, as the database holds no performance records for it.

Specification Differences

The two processors differ across nearly every specification field. The AMD Ryzen 5 PRO 8645HS belongs to the 8000 series, while the Intel Arc G3 has no series listed. The AMD part is built by AMD, the Intel part by Intel.

Part numbers differ. The AMD lists 100-000001315 (FP7r2) and 100-000001388 (FP7). The Intel lists SA4QZ.

The Intel part's memory bandwidth of 136.5 GB/s exceeds the AMD's 89.6 GB/s, and its PCIe generation is newer at Gen 5 versus Gen 4, though the AMD has more PCIe lanes (20 versus 4).

Where Each One Wins

The AMD Ryzen 5 PRO 8645HS wins in every category where the database contains measurements. It has documented benchmark scores across Cinebench R15, R20, and R23, plus PassMark tests covering compression, encryption, extended instructions, prime numbers, floating point math, integer math, multithread, physics, random string sorting, and single-thread performance. Its 82nd percentile ranking and average score of 30879 give it a measurable performance profile.

The AMD part also wins on ECC memory support, which the Intel lacks. It has a higher base clock of 4.30 versus 1.90 and a higher boost clock of 5.00 versus 4.60. It offers more PCIe lanes at 20 versus 4.

The Intel Arc G3 wins on specifications that the database records. It has more cores (14 versus 6) and more threads (14 versus 12). It has a higher memory bandwidth at 136.5 GB/s versus 89.6 GB/s. It uses a newer process node at 3 nm versus 4 nm. It has a newer PCIe generation at Gen 5 versus Gen 4. It has larger L1 cache per core at 192 KB versus 64 KB, larger L2 cache per core at 2.5 MB versus 1 MB, and larger L3 cache at 18 MB versus 16 MB. It has a lower TDP at 25 versus 45.

The Intel part also has a later release date of 2026-05-27 versus 2024-04-15.

For any performance-based use case, the AMD Ryzen 5 PRO 8645HS is the only processor with recorded evidence. For use cases prioritizing core count, memory bandwidth, cache capacity, or power efficiency as listed in the specifications, the Intel Arc G3 holds the advantage on those fields as recorded.
