AMD Ryzen AI 9 HX PRO 475 vs Intel Arc G3 EXTREME Comparison

Where Each One Wins

The recorded benchmark data splits these two mobile processors into clearly distinct roles. The AMD Ryzen AI 9 HX PRO 475 wins 7 of the 11 head-to-head comparisons, while the Intel Arc G3 EXTREME takes 4. The AMD part dominates in workloads that scale with thread count and data throughput, while the Intel part shows strength in specialized math and physics simulations.

The AMD processor wins decisively in integer math, data compression, extended instruction sets, random string sorting, multithreaded operations, and single-thread performance. Its integer math score of 126,829 against Intel's 71,164 represents a 78.2% advantage, the largest margin in either direction across all recorded tests. Data compression also favors AMD heavily, with 461,650 points versus 307,094, a 50.3% lead. These results indicate a processor built for productivity applications, database work, and content creation pipelines that rely on parallel integer operations.

The Intel Arc G3 EXTREME counters with wins in prime number finding, physics calculations, floating point math, and data encryption. Its prime number score of 248 versus AMD's 130 is a 47.6% advantage, and its physics score of 2,515 versus 1,877 is 25.4% higher. Floating point math shows Intel ahead by 8.1% (86,929 versus 79,887), and data encryption edges out AMD by 3.1% (23,881 versus 23,132). These wins suggest the Intel chip handles scientific computing, simulation workloads, and cryptographic operations with greater efficiency per clock.

The single-thread contest is nearly a tie. AMD scores 4,301 and Intel scores 4,293, a difference of only 0.2%. Both processors deliver comparable responsiveness in lightly threaded tasks like web browsing and office applications. The multithreaded result favors AMD by 19% (36,487 versus 30,659), confirming that the extra threads matter when all cores are active.

Architecture Differences

The two processors take fundamentally different design approaches. The AMD Ryzen AI 9 HX PRO 475 uses the Zen 5 architecture under the Gorgon Point codename, built on a 4 nm process at TSMC. It packs 12 cores and 24 threads, relying on simultaneous multithreading to double its logical core count. The Intel Arc G3 EXTREME uses the Panther Lake codename with a 3 nm Intel process, offering 14 physical cores and 14 threads with no multithreading.

Cache hierarchies differ substantially. AMD allocates 80 KB of L1 cache per core and 1 MB of L2 per core, with 16 MB of shared L3. Intel provides 192 KB of L1 per core and 2.5 MB of L2 per core, with 18 MB of shared L3. The larger per-core caches on the Intel side help its single-thread efficiency, while AMD's larger total thread count compensates in parallel workloads.

Memory architecture also separates them. AMD supports both DDR5 and LPDDR5X memory across a dual-channel bus, delivering 89.6 GB/s of bandwidth with ECC support. Intel supports only LPDDR5X on a dual-channel bus but achieves 136.5 GB/s, a significant bandwidth advantage of roughly 52%. Intel also uses PCIe Gen 5 with 4 CPU lanes, while AMD uses PCIe Gen 4 with 16 CPU lanes.

The integrated graphics differ as well. AMD pairs its CPU with the Radeon 890M, while Intel uses the Arc B390. Both processors target the mobile segment and share a similar thermal envelope, with AMD rated at 28 W and Intel at 25 W. AMD's die measures 233 mm², while Intel's die size is not recorded in the database. Neither processor has an unlocked multiplier.

Head-to-Head Benchmarks

The largest single benchmark gap belongs to AMD in integer math. The 126,829 score against 71,164 gives AMD a 78.2% advantage, reflecting its 24 threads processing integer operations far more efficiently than Intel's 14 threads. Data compression shows AMD ahead by 50.3% (461,650 versus 307,094), reinforcing the thread-count advantage in throughput-bound tasks.

AMD also wins extended instructions by 33.1% (31,969 versus 24,017) and random string sorting by 31% (48,894 versus 37,331). The multithread score of 36,487 versus 30,659 gives AMD a 19% lead, consistent with its 24-thread design. Single-thread performance is effectively identical, with AMD ahead by just 0.2% (4,301 versus 4,293).

Intel's largest win comes in prime number finding, where its 248 score beats AMD's 130 by 47.6%. This test typically rewards raw per-core speed and integer division efficiency, areas where Intel's newer 3 nm process and larger per-core caches appear to help. Physics simulation shows Intel ahead by 25.4% (2,515 versus 1,877), a notable margin for a workload that mixes floating point and branch prediction.

Floating point math goes to Intel by 8.1% (86,929 versus 79,887), while data encryption is a narrow Intel win at 3.1% (23,881 versus 23,132). These results indicate that Intel's architecture handles certain specialized instruction patterns more efficiently, even while losing the broader multithreaded contest.

The overall average benchmark scores reflect a different picture. AMD's average score is 74,496, placing it in the 94th percentile of all CPUs. Intel's average score is 36,699, placing it in the 85th percentile. This large gap in average score stems from AMD's inclusion of more PassMark tests with higher absolute values, while Intel's recorded benchmarks include Cinebench results that are not part of the PassMark average.

The Verdict

The data points to the AMD Ryzen AI 9 HX PRO 475 for users who prioritize multithreaded productivity and data-heavy workloads. Its 24 threads deliver a 19% lead in multithread performance, a 50.3% lead in data compression, and a 78.2% lead in integer math. The chip also edges out Intel in single-thread performance by 0.2%, making it the stronger all-rounder for mixed use. The 94th percentile ranking places it among the top processors in the database, while Intel sits at the 85th percentile.

The Intel Arc G3 EXTREME suits workloads that stress floating point arithmetic, prime number computation, and physics simulation. Its 47.6% win in prime number finding and 25.4% win in physics are substantial margins. The higher memory bandwidth of 136.5 GB/s and the 3 nm process node suggest efficiency advantages in memory-bound scenarios, even though the overall benchmark average is lower. Intel also wins data encryption by 3.1%, a factor for security-focused applications.

For a laptop buyer, the choice depends on the primary workload. The AMD chip handles compression, sorting, and integer-heavy tasks with clear superiority. The Intel chip handles scientific and cryptographic workloads with measurable advantages. The near-tie in single-thread performance means everyday responsiveness will feel similar. The AMD processor's ECC support and larger PCIe lane count (16 versus 4) further tilt the balance toward AMD for professional and server-adjacent use cases. The Intel processor's higher memory bandwidth and newer process node give it a narrower but real edge in specific compute patterns. Neither chip has an unlocked multiplier, so overclocking is not a differentiator.
