Where Each One Wins

The AMD Ryzen AI 9 HX PRO 375 dominates in rendering and compute-heavy workloads. The Cinebench suite, which stresses sustained multicore and single-core execution, goes entirely to AMD. The R23 multicore result, with a 94.7% lead, indicates a strong advantage for long-duration rendering tasks. Integer math, data compression, extended instructions, and random string sorting also favor AMD, suggesting a general-purpose compute advantage in productivity and code compilation scenarios.

The Intel Arc G3 EXTREME shows strength in specialized numerical workloads. The find prime numbers result, a 49.6% win, points to an advantage in algorithms that rely on tight loops and integer iteration. Floating point math, with a 14.2% lead, suggests a capability edge in scientific or simulation workloads that depend on FP32 or FP64 throughput. The physics test, a 26.7% win, reinforces this pattern. Data encryption, an 11.3% win, indicates a hardware assist or more efficient instruction path for cryptographic operations. The PassMark single-thread score of 4,293 versus 3,914 gives Intel an 8.8% edge in lightweight, single-threaded tasks.

The split is not merely about core count. The AMD part uses 12 cores and 24 threads, while Intel uses 14 cores and 14 threads, yet AMD still wins most multithreaded tests. The PassMark multithread result (33,689 versus 30,659) shows AMD ahead despite fewer physical cores, which points to the efficiency of simultaneous multithreading. The single-thread PassMark result, however, goes to Intel, showing that raw per-thread throughput in certain workloads is not the same as the Cinebench single-core result, where AMD leads by a wide margin.

Specification Differences

The two processors differ in nearly every fundamental specification. The AMD Ryzen AI 9 HX PRO 375 has 12 cores and 24 threads, while the Intel Arc G3 EXTREME has 14 cores and 14 threads. Base clocks are close: 2.00 GHz for AMD versus 1.90 GHz for Intel. Boost clocks differ more, with AMD reaching 5.10 GHz and Intel 4.70 GHz. Thermal design power is similar, 28 W for AMD and 25 W for Intel, but the socket and platform differ entirely. AMD uses Socket FP8, Intel uses BGA 2540.

Cache structures are distinct. AMD provides 80 KB of L1 per core, 1 MB of L2 per core, and 16 MB of L3. Intel provides 192 KB of L1 per core, 2.5 MB of L2 per core, and 18 MB of shared L3. Memory support overlaps on LPDDR5X, but AMD also supports DDR5. Both use dual-channel memory buses, yet measured bandwidth differs: 89.6 GB/s for AMD versus 136.5 GB/s for Intel. ECC memory is supported by AMD but not by Intel. PCIe generations differ as well: AMD offers Gen 4 with 16 lanes, Intel offers Gen 5 with 4 lanes. The integrated graphics units are named differently, Radeon 890M for AMD and Arc B390 for Intel. Neither processor has an unlocked multiplier.

Architecture Differences

The underlying architectures are generationally and structurally different. AMD uses the Zen 5 architecture on a 4 nm TSMC process, with the codename Strix Point. The generation field indicates a Zen 5 / Zen 5c hybrid arrangement within the Ryzen AI PRO 300 family. Intel uses the Panther Lake codename under the Arc G3 generation, fabricated on Intel's 3 nm process. The die size is recorded for AMD at 233 mm², while Intel's die size is not recorded.

The cache hierarchy suggests different design philosophies. Intel allocates more L1 per core (192 KB versus 80 KB) and more L2 per core (2.5 MB versus 1 MB), while AMD's L3 is 16 MB versus Intel's 18 MB shared. The larger per-core caches on the Intel side may explain its wins in prime number finding and physics, where data locality matters. The AMD side, with a hybrid Zen 5 and Zen 5c core arrangement, appears to prioritize throughput per watt, which shows in the Cinebench results.

The memory bandwidth gap is notable. Intel's 136.5 GB/s versus AMD's 89.6 GB/s gives Intel a 52.3% bandwidth advantage on paper, yet AMD still wins most memory-sensitive tests like data compression and random string sorting. This suggests that the AMD memory controller and cache usage patterns compensate for lower peak bandwidth. The PCIe difference is also significant: AMD provides 16 Gen 4 lanes, Intel only 4 Gen 5 lanes. For external GPU or NVMe expansion, the AMD part offers more physical lanes, while Intel's fewer lanes run at a newer standard.

ECC support is another architectural differentiator. AMD enables ECC memory, Intel does not. This positions the AMD part for reliability-sensitive workloads, while the Intel part targets a different segment. The production status for both is listed as active, with AMD's release date in early 2025 and Intel's in mid-2026.

The Verdict

The data points to a straightforward conclusion for rendering and general compute. The AMD Ryzen AI 9 HX PRO 375 outperforms the Intel Arc G3 EXTREME in 11 of 17 benchmarks, including every Cinebench test. The R23 multicore margin of 94.7% and single-core margin of 116.3% are decisive. For users running CPU-bound rendering, code compilation, or data compression, the AMD part is the stronger choice based on the recorded scores.

The Intel Arc G3 EXTREME is the better option for specific numerical workloads. Its 49.6% win in prime number finding, 26.7% win in physics, and 14.2% win in floating point math indicate a specialization in simulation and scientific computing. The 11.3% encryption win and 8.8% single-thread PassMark win add to its profile. For workloads that match these patterns, the Intel part delivers measurable advantages.

The average benchmark scores summarize the overall standing. AMD averages 47,022, which places it in the 89th percentile and within 0.6% of several high-end desktop rivals like the Intel Core i7-13700K and Core i9-12900F. Intel averages 36,699, in the 85th percentile and within 1.1% of the AMD Ryzen AI 7 PRO 450. The nearest rival data shows that the AMD part competes at a higher performance tier, while the Intel part sits closer to mid-range mobile processors.

The specification and architecture differences explain the benchmark outcomes. AMD's 12 cores with 24 threads provide a throughput advantage in multithreaded tests, while Intel's 14 cores without SMT limit its parallel performance. The higher boost clock on AMD, 5.10 GHz versus 4.70 GHz, contributes to the single-core Cinebench wins. Intel's larger per-core caches and higher memory bandwidth support its wins in cache-sensitive and bandwidth-heavy numerical tasks. The choice depends entirely on the workload profile: AMD for broad compute and rendering dominance, Intel for specialized math, physics, and encryption tasks.
