Architecture Differences

The Intel Arc G3 EXTREME and Intel Core 3 N355 represent two distinct points in Intel's mobile processor lineup. The Arc G3 EXTREME is part of the Panther Lake generation, built on a 3 nm process. The Core 3 N355 is from the Twin Lake generation with the Core 3 (Alder Lake-N) family, using a 10 nm process. This process gap directly influences power characteristics and performance ceilings.

The core configurations differ substantially. The Arc G3 EXTREME has 14 cores and 14 threads, while the Core 3 N355 has 8 cores and 8 threads. Neither part uses hyper-threading, so thread counts equal core counts. The Arc G3 EXTREME's boost clock reaches 4.70 GHz, compared to 3.90 GHz for the Core 3 N355. Both share a 1.90 GHz base clock.

Cache hierarchies are structured differently. The Arc G3 EXTREME provides 192 KB of L1 cache per core, 2.5 MB of L2 cache per core, and 18 MB of shared L3 cache. The Core 3 N355 offers 96 KB of L1 per core, 2 MB of shared L2, and 6 MB of shared L3. The Arc G3 EXTREME thus has both more total cache and a per-core L2 design, which typically benefits workloads with high data locality.

Memory support diverges sharply. The Arc G3 EXTREME supports LPDDR5X memory over a dual-channel bus with 136.5 GB/s of bandwidth. The Core 3 N355 supports DDR4, DDR5, and LPDDR5 over a single-channel bus with 38.4 GB/s of bandwidth. The 3.5x bandwidth advantage for the Arc G3 EXTREME is among the largest structural differences between the two.

PCIe connectivity also differs. The Arc G3 EXTREME uses Gen 5 with 4 CPU lanes, whereas the Core 3 N355 uses Gen 3 with 9 CPU lanes. The newer PCIe generation provides higher per-lane bandwidth for attached devices, though the Core 3 N355 offers more total lanes.

Thermal design power scales accordingly: the Arc G3 EXTREME has a 25 W TDP, the Core 3 N355 has a 15 W TDP. Both use BGA sockets, but they are not interchangeable: the Arc G3 EXTREME uses Intel BGA 2540, the Core 3 N355 uses Intel BGA 1264. Neither processor has an unlocked multiplier, and both target the mobile market segment.

Head-to-Head Benchmarks

The benchmark data shows a complete sweep: the Arc G3 EXTREME wins all 17 recorded head-to-head tests, with the Core 3 N355 recording zero wins. The margins vary widely by workload type.

Multi-core rendering tests show the largest absolute gaps. In Cinebench R20 multi-core, the Arc G3 EXTREME scores 10945 versus 3612, a 203% delta. Cinebench R15 multi-core shows a 166.7% lead (2192 versus 822). Cinebench R23 multi-core follows with 14655 versus 5262, a 178.5% advantage. These results indicate the Arc G3 EXTREME's additional cores and higher boost clock translate directly into sustained rendering throughput.

Single-core tests show a smaller but still decisive gap. The R20 single-core test shows a 203.5% lead (1545 versus 509), the largest single-thread margin in the Cinebench suite. R15 single-core shows 58.9% (267 versus 168), and R23 single-core shows 79.2% (1862 versus 1039). PassMark single-thread shows 4293 versus 2153, a 99.4% lead. The Arc G3 EXTREME's higher boost clock and newer architecture clearly drive these wins.

Specialized instruction workloads reveal the most extreme deltas. PassMark extended instructions shows a 302.4% advantage for the Arc G3 EXTREME (24017 versus 5968). PassMark physics shows the same 302.4% delta (2515 versus 625). PassMark find prime numbers delivers the largest relative margin: 248 versus 27, an 818.5% lead. This last result suggests a massive advantage in integer-heavy, iterative computation.

Cryptography and data compression favor the Arc G3 EXTREME heavily. PassMark data encryption shows 23881 versus 8121, a 194.1% delta. Data compression shows 307094 versus 117435, a 161.5% lead. Random string sorting shows 37331 versus 14706, a 153.8% margin.

Floating-point and integer math also favor the Arc G3 EXTREME. Floating-point math scores 86929 versus 22695, a 283% delta. Integer math scores 71164 versus 33894, a 110% lead. The floating-point margin is more than double the integer margin, indicating the Arc G3 EXTREME's architecture provides disproportionate strength in FP-heavy calculations.

The Verdict

The recorded data points to a single conclusion: the Intel Arc G3 EXTREME outperforms the Intel Core 3 N355 in every measured benchmark category. The average score difference is 36699 versus 13492, placing the Arc G3 EXTREME at the 85th percentile of all CPUs and the Core 3 N355 at the 68th percentile. The nearest rivals for the Arc G3 EXTREME include the Intel Core Ultra 5 225 (avg score 36938, delta -0.6%) and the AMD Ryzen 5 5600F (avg score 36945, delta -0.7%), which place it in the upper mid-range of desktop-class performance. The Core 3 N355's nearest rivals are the Intel Core i3-12100F (avg score 13494, delta 0%) and the Intel Core i5-9500 (avg score 13452, delta 0.3%), positioning it as a lower-tier part.

The Arc G3 EXTREME's 14 cores, 4.70 GHz boost clock, 18 MB L3 cache, and dual-channel LPDDR5X memory with 136.5 GB/s bandwidth produce consistent wins across rendering, encryption, compression, and math workloads. The Core 3 N355's 8 cores, 3.90 GHz boost clock, 6 MB L3 cache, and single-channel memory with 38.4 GB/s bandwidth cannot match these figures. The 3 nm process versus 10 nm process further explains the performance differential.

For users selecting a processor from these two options, the data supports the Arc G3 EXTREME for any workload that benefits from higher core counts, faster memory, or newer architecture. The Core 3 N355 offers a lower 15 W TDP, which may suit power-constrained designs, but the benchmark suite shows no performance scenario where it wins.

Where Each One Wins

The Arc G3 EXTREME wins in all 17 recorded benchmark tests. The largest margins appear in specialized computation: find prime numbers (818.5% delta), extended instructions (302.4%), physics (302.4%), and floating-point math (283%). These results point to use cases involving scientific computing, numerical simulation, and instruction-set-heavy workloads.

The Arc G3 EXTREME also dominates multi-core rendering, with Cinebench R20 showing a 203% lead and R23 showing 178.5%. This suggests strong suitability for 3D rendering, video encoding, and compilation tasks that scale with core count and cache size. The data encryption (194.1%) and data compression (161.5%) wins indicate advantages in file archiving, database workloads, and security-related processing.

The Core 3 N355 has no benchmark wins in the database. Its 15 W TDP and single-channel memory configuration may appeal to low-power designs, but the measured data shows it trailing by at least 58.9% in the closest test (Cinebench R15 single-core) and by 818.5% in the most extreme test (find prime numbers). The Core 3 N355's nearest rival, the Intel Core i3-12100F, has a nearly identical average score (13494 versus 13492, delta 0%), indicating the Core 3 N355 performs at a comparable level to older desktop quad-core parts.

The use-case split is therefore unambiguous. Workloads requiring maximum throughput, memory bandwidth, or single-thread responsiveness belong to the Arc G3 EXTREME. The Core 3 N355's only distinguishing characteristics are its lower TDP and support for multiple memory types (DDR4, DDR5, LPDDR5), which may matter for specific system designs but do not translate into any measured performance advantage.
