Architecture Differences

The AMD Ryzen AI 7 450 and Intel Arc G3 represent fundamentally different design approaches. The AMD part is built on the Zen 5 architecture under the Gorgon Point codename, part of the Ryzen AI 400 generation. The Intel part uses the Panther Lake codename under the Arc G3 generation. These are not just different brands; they are different silicon designs targeting the same mobile market segment.

The process node difference is significant. AMD uses a 4 nm process from TSMC, while Intel uses a 3 nm process from its own foundry. The Intel part's 3 nm process is a smaller node, which typically allows for higher transistor density. However, the database shows the AMD part has a die size of 195 mm², while the Intel part's die size is not recorded.

Cache hierarchies differ substantially. The AMD Ryzen AI 7 450 has 80 KB of L1 cache per core, 1 MB of L2 cache per core, and 8 MB of L3 cache. The Intel 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. The Intel part has larger per-core caches at every level and more than double the L3 cache, which can benefit workloads with large working sets.

The core topology is also different. The AMD part has 8 cores and 16 threads, implying simultaneous multithreading. The Intel part has 14 cores and 14 threads, meaning no multithreading per core. Despite having more physical cores, the Intel part has fewer threads because it does not implement SMT.

Memory support differs in scope. The AMD part supports both DDR5 and LPDDR5X memory, while the Intel part supports only LPDDR5X. Both use a dual-channel memory bus. The memory bandwidth figures show the Intel part at 136.5 GB/s versus the AMD part at 89.6 GB/s, a substantial difference in theoretical memory throughput.

PCIe support also differs. The AMD part uses Gen 4 with 16 lanes (CPU only). The Intel part uses Gen 5 with 4 lanes (CPU only). The Intel part has a newer PCIe generation but far fewer lanes.

Where Each One Wins

The AMD Ryzen AI 7 450 has a clear advantage in the areas measured by the database. Its 87th percentile standing versus the Intel part's 50th percentile standing indicates the AMD part outperforms the majority of CPUs in the database, while the Intel part sits at the median. The AMD part has 15 recorded benchmark scores across Cinebench and Passmark tests, while the Intel part has no recorded scores, meaning all direct comparisons favor the AMD part by default in the current data.

The AMD part's 16 threads versus the Intel part's 14 threads gives it an advantage in multithreaded workloads, assuming similar per-thread performance. The AMD part's higher boost clock of 5.10 GHz versus 4.60 GHz suggests an advantage in single-threaded performance, though the Intel part's larger cache hierarchy could partially offset this in certain workloads.

The Intel Arc G3 wins on specifications that favor memory bandwidth and cache capacity. Its 136.5 GB/s memory bandwidth is 52% higher than the AMD part's 89.6 GB/s. Its 18 MB of shared L3 cache is more than double the AMD part's 8 MB. These characteristics could benefit workloads that are memory-bandwidth-bound or have large data sets that fit in cache.

The Intel part also has more physical cores at 14 versus 8. In workloads that scale with core count and do not benefit from SMT, the Intel part could have an advantage. However, without recorded benchmark scores for the Intel part, the database cannot confirm this.

The TDP difference is small, with the AMD part at 28 W and the Intel part at 25 W. Both are mobile processors with similar power envelopes.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark results between the AMD Ryzen AI 7 450 and the Intel Arc G3. The headToHeadBenchmarks field is empty, and the winsA and winsB counters are both at zero. This means the comparison must rely on the individual benchmark scores recorded for the AMD part and the specification differences between the two.

The AMD Ryzen AI 7 450 has 15 recorded benchmark scores. Its strongest results include a Cinebench R23 multi-core score of 18,316 and a single-core score of 2,038. In Cinebench R15, it scores 2,713 multi-core and 215 single-core. Passmark results show 88,531 in integer math, 54,447 in floating point math, 26,350 in multithread, and 3,901 in single-thread tests. Data compression scores 315,906, data encryption scores 16,247, and extended instructions score 22,400. Physics scores 1,578, find prime numbers scores 89, and random string sorting scores 35,648.

The Intel Arc G3 has no recorded benchmark scores in the database. Its average benchmark score is 0, and it has no nearest rivals listed. This means the database currently cannot provide any measured performance comparison between the two processors.

The AMD part's nearest rivals provide context for its performance level. The AMD Ryzen 7 PRO 8840HS has an average score of 39,603, which is 0.3% higher than the Ryzen AI 7 450's 39,485. The AMD Ryzen 7 PRO 8845HS scores 39,325, which is 0.4% lower. The AMD EPYC 4245P scores 39,215, which is 0.7% lower. The AMD Ryzen 7 9800X3D scores 39,768, which is 0.7% higher. These rivals are all within 1% of the Ryzen AI 7 450's average score, indicating the AMD part performs at a consistent level with these established processors.

The specification advantages of the Intel Arc G3 in memory bandwidth and cache size cannot be translated into benchmark predictions without recorded scores. The database shows the Intel part at the 50th percentile of all CPUs, which is a lower standing than the AMD part's 87th percentile. However, the percentile field for the Intel part may reflect its specification-based classification rather than measured performance, given the absence of benchmark data.
