Intel Arc G3 vs Intel Core 3 100UL Comparison

The Verdict

The database places both processors at the 50th percentile among all CPUs, with no recorded benchmark scores or head-to-head wins for either part. The Intel Arc G3 and Intel Core 3 100UL are therefore statistically indistinguishable in measured performance so far, but their design targets diverge sharply.

The Arc G3 is a mobile-first part built on Panther Lake with 14 cores, a 25 W TDP, and an integrated Arc B370 graphics engine. It suits thin-and-light notebooks where CPU throughput and GPU capability share one package. The Core 3 100UL is a desktop-oriented Raptor Lake-PS chip with 6 cores, 8 threads, and a 15 W TDP. It fits low-power desktop boards, particularly those using the Intel Socket 1700 platform with DDR4 or DDR5 memory.

Pick the Arc G3 if the workload favors many cores and a newer 3 nm process, or if integrated graphics matter for light gaming or media tasks. Pick the Core 3 100UL if the platform requires Socket 1700 compatibility, lower power draw, or legacy DDR4 support. Neither part has a confirmed performance advantage in the current data, so the choice rests on socket, memory, and graphics requirements rather than measured speed.

Architecture Differences

The two chips come from different Intel design generations. The Arc G3 uses the Panther Lake architecture and is fabricated on a 3 nm process at Intel's own foundry. The Core 3 100UL uses Raptor Lake architecture on a 10 nm process, also Intel-built. The Arc G3's process node is three generations ahead in lithography, which typically enables higher transistor density and better power efficiency per clock.

Core counts differ substantially. The Arc G3 has 14 cores and 14 threads, meaning every core is a single-threaded unit with no hyperthreading. The Core 3 100UL has 6 cores and 8 threads, indicating two of its cores support hyperthreading. The Arc G3 offers more than double the physical cores, while the Core 3 100UL offers fewer cores but some multithreading capability.

Cache hierarchies also diverge. The Arc G3 carries 192 KB of L1 per core, 2.5 MB of L2 per core, and 18 MB of shared L3. The Core 3 100UL has 80 KB of L1 per core, 1.25 MB of L2 per core, and 10 MB of shared L3. The Arc G3's per-core caches are larger at every level, and its shared L3 is 8 MB larger.

Memory support marks a clear split. The Arc G3 exclusively supports LPDDR5X over a dual-channel bus with a recorded 136.5 GB/s of bandwidth. The Core 3 100UL supports both DDR4 and DDR5 over a dual-channel bus, but the database lists no bandwidth figure for it. The Arc G3's memory bandwidth is explicit, while the Core 3 100UL's is unmeasured.

PCIe connectivity differs as well. The Arc G3 provides Gen 5 with 4 lanes for the CPU. The Core 3 100UL provides Gen 4 with 8 lanes. The Arc G3 uses a newer PCIe generation but fewer lanes, while the Core 3 100UL offers double the lane count on the previous generation.

Integrated graphics separate the two clearly. The Arc G3 includes an Arc B370 iGPU, a dedicated graphics architecture that scales well beyond basic display output. The Core 3 100UL includes UHD Graphics 64EU, a more modest integrated solution aimed at standard desktop tasks.

The socket and market segment reinforce their different roles. The Arc G3 uses Intel BGA 2540 and is classified as Mobile. The Core 3 100UL uses Intel Socket 1700 and is classified as Desktop. The Arc G3 is soldered to the board, while the Core 3 100UL can be socketed. Release dates also differ: the Arc G3 is dated May 2026, while the Core 3 100UL is dated April 2024, making the Arc G3 the newer part by over two years.

Head-to-Head Benchmarks

The database contains no head-to-head benchmark results for these two processors. The winsA and winsB fields both read zero, and the headToHeadBenchmarks array is empty. Similarly, each processor has an empty benchmarks list and zero average benchmark score. Their percentileVsAllCpus values are identical at 50, placing both at the median of all recorded CPUs.

This absence of measured data does not mean the chips perform equally in practice, only that the database has not yet recorded comparative results. The architectural differences suggest where each part would likely lead if benchmarks were run.

The Arc G3's 14 cores versus 6 cores gives it a theoretical advantage in heavily threaded workloads such as video encoding, 3D rendering, or software compilation. The Core 3 100UL's 8 threads against 14 threads means the Arc G3 would likely dominate multi-threaded tests, although the Core 3 100UL's hyperthreading on two cores narrows the gap slightly. The Arc G3 also boosts 0.10 GHz higher, reaching 4.60 GHz versus 4.50 GHz, which would help single-threaded performance as well.

The Core 3 100UL's lower 15 W TDP versus 25 W gives it a power efficiency edge in sustained loads, potentially allowing fanless or passively cooled desktop designs. The Arc G3's larger cache hierarchy, with 18 MB L3 versus 10 MB, would benefit workloads that repeatedly access a working set larger than 10 MB. The Arc G3's 136.5 GB/s memory bandwidth, enabled by LPDDR5X, would show a clear lead in memory-bound tests, though the Core 3 100UL's unspecified bandwidth could prove competitive with DDR5 modules.

The integrated GPU comparison favors the Arc G3 in any graphics benchmark. Arc B370 is a discrete-class GPU architecture, whereas UHD Graphics 64EU is a basic integrated engine. The Arc G3 would likely win in gaming, video playback, and GPU-accelerated compute tests. The Core 3 100UL's UHD Graphics 64EU would still handle standard desktop output and video decode, but with far lower compute headroom.

PCIe bandwidth also splits the two. The Arc G3 uses Gen 5 with 4 lanes, which provides high per-lane bandwidth but limited total throughput. The Core 3 100UL uses Gen 4 with 8 lanes, doubling the lane count. For storage or discrete GPUs, the Core 3 100UL's extra lanes could matter, while the Arc G3's newer generation offers faster signaling per lane.

Without recorded benchmark scores, the database cannot certify a winner. The specification sheet points to the Arc G3 as the stronger compute part on paper, with more cores, larger caches, newer process, faster memory, and superior integrated graphics. The Core 3 100UL counters with lower power, socket compatibility, and broader memory support. The 50th percentile ranking for both suggests they occupy similar positions in the overall CPU landscape, but the data does not yet capture their relative performance directly. Future benchmark entries will be required to settle the comparison numerically.
