Intel Arc G3 vs Intel Core 3 N355 Comparison

Where Each One Wins

The recorded data splits these two mobile processors cleanly by workload type. The Intel Arc G3, based on the Panther Lake architecture, has no individual benchmark entries in the database, which means the comparison relies on the available measurements for the Intel Core 3 N355 and the architectural specifications of both parts. The Core 3 N355 shows a strong profile across a wide range of tests, with its highest relative performance in integer math, floating point math, and multithreaded workloads.

The Core 3 N355 delivers a Passmark multithread score of 10174, a floating point math score of 22695, and an integer math score of 33894. These numbers place it in the upper portion of the database, with a percentile rank of 68 against all CPUs. The single-thread score of 2153 and the Cinebench R23 single-core score of 1039 indicate that the N355 holds its own in lightly threaded tasks as well, though the gap between its multi-core and single-core results suggests the processor scales well when all eight cores are engaged.

The Arc G3, by contrast, comes with 14 cores and 14 threads, a boost clock of 4.60 GHz, and 18 MB of shared L3 cache. The database shows no benchmark scores for the Arc G3, so its wins cannot be quantified directly. The architectural data indicates that it should take the lead in heavily threaded scenarios, given the 14-core configuration versus the 8-core N355, and in memory bandwidth, where the Arc G3 supports dual-channel LPDDR5X at 136.5 GB/s versus the N355's single-channel 38.4 GB/s. The Arc G3 also uses a 3 nm process node, which suggests higher efficiency potential at comparable power levels.

Architecture Differences

The two processors come from different Intel design families. The Arc G3 uses the Panther Lake codename with a 3 nm process node, while the Core 3 N355 uses the Twin Lake architecture with a 10 nm node. The generation field for the Arc G3 is listed as "Arc G3 (Panther Lake)", while the N355 is listed as "Core 3 (Alder Lake-N)", though the architecture field for the N355 is Twin Lake.

Core and thread counts differ substantially. The Arc G3 has 14 cores and 14 threads, meaning no hyperthreading. The N355 has 8 cores and 8 threads, also without hyperthreading. The base clocks are the same at 1.90 GHz, but the boost clocks differ: 4.60 GHz for the Arc G3 and 3.90 GHz for the N355.

Cache hierarchies are distinct. The Arc G3 allocates 192 KB of L1 per core and 2.5 MB of L2 per core, with 18 MB of shared L3. The N355 uses 96 KB of L1 per core, 2 MB of shared L2, and 6 MB of shared L3. The L2 design is particularly notable: per-core L2 on the Arc G3 versus a shared L2 pool on the N355.

Memory support also diverges. The Arc G3 supports LPDDR5X memory over a dual-channel bus with 136.5 GB/s of bandwidth. The N355 supports DDR4, DDR5, and LPDDR5 over a single-channel bus with 38.4 GB/s. Neither supports ECC memory. The PCIe interface differs as well: the Arc G3 provides Gen 5 with 4 lanes, while the N355 provides Gen 3 with 9 lanes.

Integrated graphics differ. The Arc G3 includes Arc B370 graphics, while the N355 includes UHD Graphics 770. The sockets are different: Intel BGA 2540 for the Arc G3 and Intel BGA 1264 for the N355. Both are mobile parts with active production status. The Arc G3 has a TDP of 25 watts, and the N355 has a TDP of 15 watts. The release dates are recorded as 2026-05-27 for the Arc G3 and 2025-01-06 for the N355.

The Verdict

The data supports a clear split. For workloads that stress memory bandwidth, cache capacity, and core count, the Arc G3 is the stronger part on paper. The 14-core configuration, 18 MB of L3, dual-channel LPDDR5X at 136.5 GB/s, and 4.60 GHz boost clock give it advantages that the N355 cannot match in parallel or memory-heavy tasks.

For measured performance in the database, the Core 3 N355 has the only available numbers. Its average benchmark score of 13492 places it at the 68th percentile of all CPUs. The nearest rivals show it trading blows with desktop chips: the Intel Core i3-12100F scores 13494 (a 0% delta), the Intel Core i5-9500 scores 13452 (0.3% behind), the Intel Core 5 120UL scores 13594 (0.8% ahead), and the Intel Core i7-1250U scores 13351 (1.1% behind). These deltas are small, indicating that the N355 sits in a tightly contested performance band.

The Arc G3 has no benchmark scores in the database, so its measured standing cannot be confirmed. Its specifications suggest it targets a higher tier, but without recorded results, the verdict must rely on the architectural data alone. The N355 is the only one of the two with verified scores, and those scores show it performing at a level comparable to a range of mainstream desktop and mobile processors.

Head-to-Head Benchmarks

The head-to-head benchmark array in the database is empty, so there are no direct paired test results between the Arc G3 and the Core 3 N355. The available measured scores belong entirely to the N355, and they provide the only quantitative basis for performance assessment.

The N355's Cinebench R23 multi-core score of 5262 and single-core score of 1039 show a ratio of roughly five to one, which is typical for a processor with a modest core count and a moderate boost clock. The R20 scores follow a similar pattern: 3612 multi-core and 509 single-core. The R15 scores are 822 multi-core and 168 single-core. These results indicate that the N355 scales reasonably well across all cores, but its per-thread performance is limited by the 3.90 GHz boost ceiling.

In Passmark tests, the N355 shows its strongest absolute numbers in integer math (33894) and floating point math (22695). Data compression scores 117435, random string sorting scores 14706, and extended instructions score 5968. The physics test scores 625, and the find prime numbers test scores 27. Data encryption scores 8121. The multithread score of 10174 and single-thread score of 2153 round out the profile.

The nearest rivals for the N355 provide context for these numbers. The Intel Core i3-12100F averages 13494, essentially identical to the N355's 13492. The Intel Core i5-9500 averages 13452, just 0.3% behind. The Intel Core 5 120UL averages 13594, 0.8% ahead. The Intel Core i7-1250U averages 13351, 1.1% behind. These tight margins mean the N355's measured performance falls within a narrow band around the 13400 to 13600 average score range.

The Arc G3 lacks any recorded benchmark results, so the largest wins in the database belong to the N355 by default. The Arc G3's potential advantages, based on its specifications, would appear in multi-core rendering and memory-intensive workloads, but no scores exist to confirm or quantify those gains.

Specification Differences

The two processors differ in nearly every major specification category. The Arc G3 uses a 3 nm process node, while the N355 uses a 10 nm node. The Arc G3 has 14 cores and 14 threads; the N355 has 8 cores and 8 threads. Base clocks match at 1.90 GHz, but boost clocks differ at 4.60 GHz versus 3.90 GHz.

Cache configurations are not comparable. The Arc G3 has 192 KB of L1 per core, 2.5 MB of L2 per core, and 18 MB of shared L3. The N355 has 96 KB of L1 per core, 2 MB of shared L2, and 6 MB of shared L3. The L2 design philosophy differs entirely: per-core on the Arc G3, shared on the N355.

Memory support shows a wide gap. The Arc G3 supports only LPDDR5X over a dual-channel bus at 136.5 GB/s. The N355 supports DDR4, DDR5, and LPDDR5 over a single-channel bus at 38.4 GB/s. The bandwidth difference is roughly 3.5 times in favor of the Arc G3.

PCIe connectivity differs. The Arc G3 uses Gen 5 with 4 CPU lanes. The N355 uses Gen 3 with 9 CPU lanes. The integrated graphics are different as well: Arc B370 on the Arc G3, UHD Graphics 770 on the N355.

Power and platform details also vary. The Arc G3 has a TDP of 25 watts and uses socket Intel BGA 2540. The N355 has a TDP of 15 watts and uses socket Intel BGA 1264. Both are mobile segments with active production status. The Arc G3 has a 2026-05-27 release date, while the N355 has a 2025-01-06 release date. Neither processor has an unlocked multiplier. Neither supports ECC memory. The part numbers are SA4QZ for the Arc G3 and SRPNT for the N355.
