AMD Ryzen 7 8745HX vs Intel Arc G3 Comparison

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark records for the AMD Ryzen 7 8745HX and the Intel Arc G3. The recorded data for the Intel Arc G3 shows no benchmark scores, with an average benchmark score of 0 and a percentile of 50 among all CPUs. This means direct numerical comparisons between the two processors cannot be established from measured results alone.

The AMD Ryzen 7 8745HX, however, has a full set of recorded benchmark scores. Its average benchmark score across all tests is 60,104, placing it in the 92nd percentile of all CPUs. The data shows strong performance in several specific workloads. In the PassMark multithread test, the Ryzen 7 8745HX scores 31,517. Its single-thread score is 3,879, which is a relatively strong result for a mobile processor. The data compression score reaches 363,759, while integer math scores 100,328 and floating point math scores 61,972. Extended instructions produce a score of 27,638, random string sorting yields 44,494, and data encryption scores 21,840. The physics score is 1,681, and the find prime numbers test records a score of 159.

The nearest rivals in the database for the AMD Ryzen 7 8745HX provide context for its average score. The AMD Ryzen 9 7945HX has an average score of 60,099, which is effectively identical with a delta percentage of 0. The Intel Core i9-14900F scores 60,008, putting it 0.2% behind the Ryzen 7 8745HX. The AMD Ryzen 9 7945HX3D records 59,641, a 0.8% deficit. The Intel Xeon Gold 6338T scores 60,572, which is 0.8% ahead of the Ryzen 7 8745HX. These close margins indicate that the Ryzen 7 8745HX sits at the upper edge of mainstream high-performance computing, trading leads with top-tier desktop and server parts within a narrow band.

Since the Intel Arc G3 has no recorded scores, the head-to-head comparison is asymmetric. The data implies that the Arc G3's performance profile is unverified in the database, while the Ryzen 7 8745HX is fully characterized. Any assessment of relative performance must rely on the architectural and specification differences rather than measured outcomes.

The Verdict

The data presents a clear verdict for those who prioritize verified performance: the AMD Ryzen 7 8745HX is the only processor in this comparison with recorded benchmark results. Its 92nd percentile ranking and average score of 60,104 place it among the top mobile and desktop processors in the database, with rivals like the Intel Core i9-14900F and AMD Ryzen 9 7945HX3D within 0.8% or less. Users who require proven multi-threaded and single-threaded capability from measured data should look to the Ryzen 7 8745HX, as its scores for multithread (31,517), single-thread (3,879), and data compression (363,759) are all recorded and substantial.

The Intel Arc G3, with no benchmark scores in the database, cannot be selected on the basis of measured performance. Its percentile of 50 and average score of 0 indicate a lack of recorded results rather than a specific performance level. For users who need a processor with a lower thermal envelope, the Arc G3's TDP of 25 watts compared to the Ryzen 7 8745HX's 55 watts is a notable specification difference, but the absence of benchmark data means no performance validation exists. The verdict from the data is straightforward: choose the Ryzen 7 8745HX for verified compute capability, or wait for the Arc G3's benchmark results to appear before making an informed decision based on measurements.

Specification Differences

The two processors differ across nearly every core specification in the database. The AMD Ryzen 7 8745HX uses 8 cores and 16 threads, while the Intel Arc G3 uses 14 cores and 14 threads. The Ryzen 7 8745HX has a base clock of 3.60 GHz and a boost clock of 5.10 GHz; the Arc G3 has a base clock of 1.90 GHz and a boost clock of 4.60 GHz. Thermal design power differs significantly: the Ryzen 7 8745HX is rated at 55 watts, the Arc G3 at 25 watts.

The socket types are entirely different. The Ryzen 7 8745HX uses AMD Socket FL1, while the Arc G3 uses Intel BGA 2540. The Ryzen 7 8745HX has an unlocked multiplier, while the Arc G3 does not. Memory support also diverges: the Ryzen 7 8745HX supports DDR5, the Arc G3 supports LPDDR5X. Both use dual-channel memory buses, but the memory bandwidth differs: the Ryzen 7 8745HX records 83.2 GB/s, the Arc G3 records 136.5 GB/s.

PCIe lane counts vary substantially. The Ryzen 7 8745HX supports Gen 5 with 28 lanes (CPU only), while the Arc G3 supports Gen 5 with 4 lanes (CPU only). Neither processor supports ECC memory. The integrated graphics differ: the Ryzen 7 8745HX includes Radeon 610M, while the Arc G3 includes Arc B370. The release dates are different, with the Ryzen 7 8745HX released on 2025-04-22 and the Arc G3 on 2026-05-27. Both are active production parts, and neither has a launch MSRP recorded in the database.

Architecture Differences

The architectural split is fundamental. The AMD Ryzen 7 8745HX is built on Zen 4 architecture with the codename Dragon Range, part of the 8000 series and the Ryzen 7 generation. The Intel Arc G3 uses the Panther Lake codename and belongs to the Arc G3 generation. The process nodes differ: the Ryzen 7 8745HX uses a 5 nm process from TSMC, while the Arc G3 uses a 3 nm process from Intel. The Ryzen 7 8745HX has a recorded transistor count of 6,570 million and a die size of 71 mm²; the Arc G3 has no transistor or die size data in the database.

Cache hierarchies are markedly different. The Ryzen 7 8745HX has 64 KB of L1 cache per core, 1 MB of L2 cache per core, and 32 MB of shared L3 cache. The Arc G3 has 192 KB of L1 cache per core, 2.5 MB of L2 cache per core, and 18 MB of shared L3 cache. Neither processor has a 3D V-Cache variant recorded. The core count difference of 14 versus 8, combined with the thread count of 14 versus 16, indicates a different threading model: the Ryzen 7 8745HX uses simultaneous multithreading to reach 16 threads from 8 cores, while the Arc G3 has a one-to-one core-to-thread mapping.

The memory bandwidth advantage belongs to the Arc G3 at 136.5 GB/s versus 83.2 GB/s, which may reflect the LPDDR5X memory type. The PCIe lane count is a major architectural divergence: 28 lanes for the Ryzen 7 8745HX versus 4 lanes for the Arc G3, which affects expansion capabilities for external devices. The integrated graphics solutions are also architecturally distinct, with Radeon 610M on the AMD side and Arc B370 on the Intel side, though no graphics benchmarks are recorded in the database.

Where Each One Wins

From the recorded data, the AMD Ryzen 7 8745HX wins in every measurable category because it is the only processor with benchmark scores. Its strongest recorded performances are in data compression (363,759), integer math (100,328), and floating point math (61,972), which indicate a processor well-suited to compute-heavy workloads such as scientific calculations, data processing, and encoding tasks. The multithread score of 31,517 and single-thread score of 3,879 suggest balanced capability across both parallel and single-core-dependent applications. The 16 threads from 8 cores, combined with the 5.10 GHz boost clock, position the Ryzen 7 8745HX as a strong choice for mobile workstations running multi-threaded software, while its 28 PCIe Gen 5 lanes allow for extensive peripheral connectivity, which is a clear advantage for systems requiring high-bandwidth expansion.

The Intel Arc G3 has no recorded wins in the database. Its specification profile suggests certain potential advantages: the 136.5 GB/s memory bandwidth is substantially higher than the Ryzen 7 8745HX's 83.2 GB/s, which could favor memory-intensive workloads if benchmark data existed to confirm it. The lower TDP of 25 watts, versus 55 watts for the Ryzen 7 8745HX, implies a more power-efficient design for thin-and-light mobile devices. The 14 cores and 14 threads, while lacking multithreading, provide a higher raw core count that could benefit certain parallel tasks. The 3 nm Intel process node is a more advanced manufacturing technology than the 5 nm TSMC node used by the Ryzen 7 8745HX. However, without benchmark scores, these remain theoretical advantages rather than demonstrated wins. The database currently supports only one conclusion: the AMD Ryzen 7 8745HX is the verified performer, while the Intel Arc G3 awaits measurement.
