Intel Arc G3 vs Intel Core Ultra 7 155UL Comparison

Where Each One Wins

The recorded benchmark data for the Intel Arc G3 and the Intel Core Ultra 7 155UL shows no scored test results in the database. Both processors have an empty benchmark array, and the head-to-head comparison table contains no entries. Consequently, the win count stands at zero for each part. This means the database currently offers no direct performance measurements to separate these two processors on raw speed. The absence of scores does not indicate equality; it simply reflects missing data collection for both units.

The Intel Arc G3 carries a percentile rank of 50 against all CPUs, which places it exactly at the median of the database's tracked processors. The Intel Core Ultra 7 155UL also holds a percentile rank of 50. With identical percentile positions and no benchmark scores, neither unit demonstrates a measurable advantage in any workload category based on the available facts. The average benchmark score for both items is recorded as 0, reinforcing that no aggregate performance figure exists to compare.

Without benchmark wins, the differentiation must come from architectural and specification-based analysis. The Arc G3 targets the mobile segment with a 25 TDP, while the Core Ultra 7 155UL targets the desktop segment with a 15 TDP. These market placements hint at different usage contexts, even though performance data is absent.

Architecture Differences

The two processors come from different Intel design families. The Intel Arc G3 uses the Panther Lake codename and is built on a 3 nm process node. The Intel Core Ultra 7 155UL uses the Meteor Lake architecture with the Meteor Lake-PS codename and is built on a 7 nm process node. The process node difference is substantial: the Arc G3's 3 nm fabrication offers a denser transistor layout compared to the 7 nm node of the Core Ultra 7 155UL. Both are manufactured by Intel, so the foundry is identical.

Core counts differ. The Arc G3 has 14 cores and 14 threads, meaning it runs without hyper-threading. The Core Ultra 7 155UL has 12 cores and 14 threads, indicating that two of its cores support additional threads. The thread count is identical at 14 for both, but the core distribution differs. The Arc G3 relies on more physical cores, while the Core Ultra 7 155UL uses a smaller core count with some multithreading capability.

Clock speeds show a mixed picture. The Arc G3 has a base clock of 1.90 GHz and a boost clock of 4.60 GHz. The Core Ultra 7 155UL has a lower base clock of 1.70 GHz but a higher boost clock of 4.80 GHz. The boost advantage of the Core Ultra 7 155UL is 0.20 GHz, while the Arc G3 holds a 0.20 GHz advantage at base frequency.

Cache hierarchies differ in capacity. The Arc G3 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 Ultra 7 155UL provides 112 KB of L1 cache per core, 2 MB of L2 cache per core, and 12 MB of shared L3 cache. The Arc G3 leads in every cache tier, with 80 KB more L1 per core, 0.5 MB more L2 per core, and 6 MB more L3 overall.

Memory support diverges. The Arc G3 uses LPDDR5X memory with dual-channel configuration and a bandwidth of 136.5 GB/s. The Core Ultra 7 155UL uses DDR5 memory with capacity depending on the motherboard, also dual-channel, but with a bandwidth of 89.6 GB/s. The Arc G3 offers 46.9 GB/s more memory bandwidth. Neither processor supports ECC memory.

PCIe connectivity differs. The Arc G3 provides Gen 5 with 4 lanes for the CPU only. The Core Ultra 7 155UL provides Gen 4 with 8 lanes for the CPU only. The Arc G3 uses a newer PCIe generation but with fewer lanes, while the Core Ultra 7 155UL doubles the lane count on an older generation.

Integrated graphics differ. The Arc G3 includes Arc B370 graphics. The Core Ultra 7 155UL includes Arc Xe-LPG 64EU graphics. Both are Intel Arc family implementations, but they are distinct GPU configurations.

Sockets and packaging are different. The Arc G3 uses Intel BGA 2540, a ball-grid array socket typical for mobile soldered parts. The Core Ultra 7 155UL uses Intel Socket 1851, a desktop socket. The Arc G3's part number is SA4QZ, while the Core Ultra 7 155UL's part number is SRN97. Neither processor has an unlocked multiplier.

Release timing differs. The Arc G3 has a release date of 2026-05-27, while the Core Ultra 7 155UL has a release date of 2024-04-07. The Core Ultra 7 155UL launched earlier by roughly two years. The Arc G3 belongs to the Arc G3 generation (Panther Lake), while the Core Ultra 7 155UL belongs to the Ultra 7 generation (Meteor Lake-PS).

The Core Ultra 7 155UL has a recorded launch MSRP of $426. The Arc G3 has no launch MSRP recorded in the database.

The Verdict

The data indicates no benchmark results for either processor, so a performance verdict cannot be derived from measured scores. The specification sheet provides the only basis for selection.

The Intel Arc G3 suits users who prioritize a newer process node, larger cache capacities, higher memory bandwidth, and newer PCIe generation. Its 3 nm node, 18 MB L3 cache, and 136.5 GB/s memory bandwidth position it as the more advanced silicon in raw architectural terms. The mobile segment designation and BGA 2540 socket suggest it is intended for integrated systems where soldered installation is acceptable.

The Intel Core Ultra 7 155UL suits users who require a desktop socket, higher boost clocks, and lower power draw. Its 15 TDP is 10 units lower than the Arc G3's 25 TDP, which may matter in thermally constrained desktop builds. The Socket 1851 interface allows replaceable installation. The higher 4.80 GHz boost clock gives it a single-thread frequency advantage, though no benchmark confirms how that translates to real performance.

The identical thread count of 14 means multithreaded workloads see the same thread resource in both parts. The Arc G3's extra two physical cores could provide better parallel scaling in workloads that favor physical cores over logical threads, but this is an inference from the specification, not a measured result.

The Core Ultra 7 155UL has a recorded launch MSRP of $426. The Arc G3 has no recorded launch MSRP.
