Architecture Differences
Both parts use Intel's 3 nm process, so the node is shared. The architecture labels differ: the Arc G3 carries the Panther Lake codename, while the Core 3 305 carries the Wildcat Lake codename. The core configuration is a major difference: the Arc G3 has 14 cores and 14 threads, while the Core 3 305 has 6 cores and 6 threads.
The cache hierarchy also differs. The Arc G3 lists 192 KB of L1 per core and 2.5 MB of L2 per core. The Core 3 305 lists 192 KB of L1 and 2.5 MB of L2. The shared L3 is 18 MB on the Arc G3 and 6 MB on the Core 3 305.
The memory architecture is different in both channel configuration and supported types. The Arc G3 uses dual-channel LPDDR5X with 136.5 GB/s bandwidth. The Core 3 305 uses single-channel DDR5 or LPDDR5X with 59.7 GB/s bandwidth. The PCIe implementation differs as well: the Arc G3 uses Gen 5 with 4 CPU-attached lanes, while the Core 3 305 uses Gen 4 with 6 CPU-attached lanes.
Integrated graphics differ: the Arc G3 lists Arc B370, and the Core 3 305 lists Intel Xe3 Graphics (1 Xe). The physical package differs, with the Arc G3 on Intel BGA 2540 and the Core 3 305 on Intel BGA 1516. TDP is 25 on the Arc G3 and 15 on the Core 3 305. Release dates differ, with the Arc G3 at 2026-05-27 and the Core 3 305 at 2026-04-15. Part numbers are SA4QZ for the Arc G3 and SAE3L for the Core 3 305. Both are active mobile parts, both lack ECC memory support, and neither has an unlocked multiplier.
The Verdict
The data supports a split decision. The Core 3 305 is the only part with recorded benchmark scores, an average benchmark score of 18302, and a 72nd percentile standing. The Arc G3 has no recorded benchmark scores and sits at the 50th percentile. A direct performance winner cannot be declared because the head-to-head record is empty.
On listed specifications, the Arc G3 leads in cores, threads, clock speeds, L3 cache, memory bandwidth, PCIe generation, and integrated graphics tier. The Core 3 305 leads in memory type flexibility, PCIe lane count, TDP, and measured performance evidence. The selection criterion determines the pick: measured performance points to the Core 3 305, while listed specifications point to the Arc G3.
