AMD Ryzen AI Max PRO 390 vs Intel Arc G3 Comparison

Where Each One Wins

The AMD Ryzen AI Max PRO 390 and the Intel Arc G3 occupy different positions in the mobile processor landscape. The AMD part is a high-performance, high-core-count processor aimed at demanding workloads, while the Intel Arc G3 is a lower-power, efficiency-focused chip. The data shows a clear split in their intended use cases.

The AMD Ryzen AI Max PRO 390 has 12 cores and 24 threads, which gives it a substantial advantage in heavily threaded applications. Its benchmark scores are extensive and consistently strong across multi-core tests. The recorded data shows a Cinebench R23 multi-core score of 24,828 and a Passmark multi-thread score of 42,912. This processor is clearly positioned for content creation, software compilation, and other parallel workloads that can utilize many threads simultaneously.

The Intel Arc G3, by contrast, does not have any benchmark scores recorded in the database. Its configuration is notable for its efficiency: a TDP of only 25 watts compared to the AMD part's 55 watts. The Intel chip uses 14 cores and 14 threads, meaning it has no hyper-threading, which limits its multi-threaded capacity. This processor appears designed for sustained battery life and lighter workloads where energy consumption is a priority.

The percentile data reinforces this split. The AMD Ryzen AI Max PRO 390 sits at the 93rd percentile among all CPUs, indicating it outperforms the vast majority of processors in the database. The Intel Arc G3 sits at the 50th percentile, a median position that reflects its mid-range performance expectations. One is a top-tier workhorse, the other is a balanced mainstream part.

Architecture Differences

The two processors are built on fundamentally different designs. The AMD Ryzen AI Max PRO 390 uses the Zen 5 architecture on a 4 nm process node from TSMC. The Intel Arc G3 uses the Panther Lake codename on a 3 nm process node from Intel's own foundry. Both are mobile parts, but their internal designs diverge sharply.

Core and thread counts differ significantly. The AMD chip has 12 cores and 24 threads, enabling simultaneous multi-threading on every core. The Intel chip has 14 cores but only 14 threads, meaning each core handles a single thread. This makes the Intel part's higher core count less effective in heavily threaded scenarios, as the AMD chip can process nearly twice as many threads simultaneously.

Cache hierarchies are also distinct. The AMD processor provides 80 KB of L1 cache per core, 1 MB of L2 cache per core, and 64 MB of shared L3 cache. The Intel processor offers 192 KB of L1 per core, 2.5 MB of L2 per core, but only 18 MB of shared L3 cache. The AMD part's 64 MB L3 is more than three times larger, which benefits workloads with large working sets and repeated data access.

Clock speeds tell a similar story. The AMD chip has a base clock of 3.20 GHz and a boost clock of 5.00 GHz. The Intel chip has a base clock of 1.90 GHz and a boost clock of 4.60 GHz. The AMD part runs faster at both ends of the frequency range, though the Intel chip's lower base clock contributes to its reduced power draw.

Memory architecture favors AMD as well. The Ryzen AI Max PRO 390 supports quad-channel LPDDR5X memory with a bandwidth of 256.0 GB/s. The Intel Arc G3 uses dual-channel LPDDR5X with a bandwidth of 136.5 GB/s. The AMD processor has nearly double the memory bandwidth, which matters for integrated graphics performance and memory-intensive tasks. The AMD part also supports ECC memory, while the Intel part does not.

PCIe connectivity is another divergence. The AMD processor provides Gen 4 with 16 lanes for the CPU, while the Intel processor provides Gen 5 with 4 lanes. Intel's newer PCIe standard offers higher per-lane bandwidth, but the AMD part has far more lanes available for expansion and peripheral connectivity.

The integrated graphics are branded differently: the AMD chip includes a Radeon 8050S, while the Intel chip includes an Arc B370. Neither GPU has benchmark scores recorded in the database, so direct comparison is not possible from the available data. The AMD part uses AMD Socket FP11, while the Intel part uses Intel BGA 2540. Neither processor has an unlocked multiplier.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark results between the AMD Ryzen AI Max PRO 390 and the Intel Arc G3. The headToHeadBenchmarks field is empty, and the wins counters for both processors are zero. The Intel Arc G3 has no benchmark scores recorded at all, which prevents any direct numerical comparison.

The AMD processor's benchmark scores can still be interpreted against its nearest rivals in the database. The Ryzen AI Max PRO 390 has an average benchmark score of 63,765. Its closest competitor is the Intel Core i9-13900KS with an average score of 64,051, a delta of -0.4 percent relative to the AMD chip. This means the AMD processor trails the i9-13900KS by a narrow margin. The AMD EPYC 7343 scores 64,202, putting it 0.7 percent ahead of the Ryzen AI Max PRO 390. The AMD Ryzen AI 7 450G scores 63,331, which is 0.7 percent behind the subject processor. The Intel Core Ultra 7 265HX scores 63,173, sitting 0.9 percent behind.

Individual benchmark scores for the AMD processor show its strengths. The Passmark multi-thread score of 42,912 and Cinebench R23 multi-core score of 24,828 indicate strong parallel performance. The single-thread scores are also respectable: Cinebench R23 single-core at 1,976 and Passmark single-thread at 3,967. Data encryption scores 26,027, while data compression reaches 506,170. Floating point math scores 94,666, and integer math scores 148,508.

The nearest rival data shows that the Ryzen AI Max PRO 390 competes directly with some of the strongest desktop and server processors ever released. A 0.4 percent gap to the Intel Core i9-13900KS is effectively a statistical tie. The 0.7 percent deficit to the AMD EPYC 7343, a server part, is similarly marginal. The data indicates the AMD mobile processor delivers performance comparable to high-end desktop and server silicon from recent generations.

Without any recorded scores for the Intel Arc G3, its performance relative to the AMD chip cannot be quantified. The database shows its specifications, but no measurement data exists to establish how it performs in practice. Any comparison between the two would rely on architectural differences rather than direct benchmark results.

The Verdict

The data supports a clear conclusion for the AMD Ryzen AI Max PRO 390. It delivers strong multi-threaded performance with 24 threads, a large 64 MB L3 cache, high memory bandwidth of 256.0 GB/s, and ECC support. Its average benchmark score of 63,765 places it within one percent of processors like the Intel Core i9-13900KS and the AMD EPYC 7343. The 93rd percentile ranking confirms its position among the highest-performing CPUs in the database. Users who need maximum throughput for parallel workloads should select this processor.

The Intel Arc G3 cannot be evaluated on performance grounds because no benchmark data exists in the database. Its specifications indicate a different design philosophy: 14 cores without hyper-threading, a 25-watt TDP, and a 3 nm process node. The lower power envelope suggests a focus on efficiency and battery life rather than raw performance. The 50th percentile ranking reflects its expected mainstream position, though this figure is based on its specifications rather than measured scores.

The choice between these two processors comes down to workload requirements and power constraints. The AMD chip is the performance leader by every measurable specification in the database, from clock speed to cache size to memory bandwidth. The Intel chip offers a lower power draw and a more recent 3 nm process node, but its lack of recorded scores means its actual performance cannot be verified. For any workload where multi-threaded performance matters, the AMD Ryzen AI Max PRO 390 is the data-backed choice. For scenarios prioritizing minimal power consumption, the Intel Arc G3 has the lower TDP but its performance remains an unknown quantity in the recorded data.
