AMD Ryzen AI 7 450G vs Intel Arc G3 Comparison

The Verdict

The data presents an unusual pairing. The AMD Ryzen AI 7 450G is an established desktop processor with a robust benchmark record, while the Intel Arc G3 is a mobile part with no recorded benchmark scores in the database. The verdict is therefore conditional: for any scenario requiring verified performance data, the AMD Ryzen AI 7 450G is the only option with measurable results. The Intel Arc G3, sitting at the 50th percentile among all CPUs with an average benchmark score of zero, offers no evidence of capability. The Ryzen AI 7 450G, by contrast, achieves a 93rd percentile ranking and an average benchmark score of 63331. The nearest rival data for the AMD part shows it is closely competitive with the Intel Core Ultra 7 265HX, which scores 63173, a delta of 0.2%. The AMD processor also edges out the Intel Core i7-13790F by 0.4% and the AMD Ryzen AI Embedded P185 by 0.8%, while trailing the AMD Ryzen AI Max PRO 390 by 0.7%. These margins are all within roughly one percent, placing the Ryzen AI 7 450G in a tightly contested performance tier.

Where Each One Wins

The AMD Ryzen AI 7 450G wins in every category where data exists. Its multithreaded PassMark score of 30422, single-thread score of 4309, and integer math score of 99732 all reflect a fully tested part. The data compression score of 402831 and encryption score of 18937 further demonstrate its range. The floating point math result of 63683 and extended instructions score of 28223 indicate strong compute throughput. The physics score of 1440 and random string sorting score of 42663 round out the benchmark suite. The Intel Arc G3 has no wins to claim, as its benchmark array is empty. Its 14 cores and 14 threads suggest a design without simultaneous multithreading, but without scores, the database cannot confirm any performance advantage. The AMD part uses 8 cores and 16 threads, which provides two threads per core. The Intel part's higher core count does not translate into recorded wins.

Architecture Differences

The two processors diverge fundamentally in design. The AMD Ryzen AI 7 450G uses the Gorgon Point codename, belongs to the Ryzen AI 400 generation built on Zen 5 and Zen 5c cores, and is fabricated on a 4 nm process at TSMC. Its die size is 195 mm². The Intel Arc G3 uses the Panther Lake codename, belongs to the Arc G3 generation, and is fabricated on a 3 nm process at Intel. The Intel die size is not recorded. The AMD processor has 8 cores and 16 threads, with a base clock of 2.00 GHz and a boost clock of 5.10 GHz. The Intel processor has 14 cores and 14 threads, with a base clock of 1.90 GHz and a boost clock of 4.60 GHz. The AMD part's thermal design power is 65 watts, while the Intel part is rated at 25 watts. The AMD part uses the AMD Socket AM5, the Intel part uses Intel BGA 2540. The AMD processor supports DDR5 and LPDDR5X memory with a dual-channel bus and 89.6 GB/s bandwidth. The Intel processor supports only LPDDR5X memory, also dual-channel, but with a higher 136.5 GB/s bandwidth. The AMD part supports ECC memory; the Intel part does not. The AMD processor offers PCIe Gen 4 with 12 CPU lanes, while the Intel processor offers PCIe Gen 5 with 4 CPU lanes.

Head-to-Head Benchmarks

There are no direct head-to-head benchmark entries in the database, so the comparison relies on the AMD part's recorded scores and the Intel part's absence of data. The AMD Ryzen AI 7 450G delivers a multithread score of 30422, which reflects its 16-thread capability. Its single-thread score of 4309 is the same across both PassMark single-thread test entries, confirming consistency. The integer math score of 99732 and floating point math score of 63683 show the processor's arithmetic throughput. The extended instructions score of 28223 and data encryption score of 18937 indicate strong cryptography and SIMD performance. The data compression score of 402831 is the highest single recorded value in the AMD suite, while the find prime numbers score of 87 is the lowest. The physics score of 1440 and random string sorting score of 42663 complete the set. The Intel Arc G3 has no comparable figures. Its percentile ranking of 50 versus the AMD part's 93 places it in the median range of all CPUs, while the AMD part sits well above average. The nearest rival comparison for the AMD part shows it is 0.2% ahead of the Intel Core Ultra 7 265HX and 0.4% ahead of the Intel Core i7-13790F.
