Architecture Differences

The Intel Arc G3 and the Intel Core Ultra 5 336H share a common foundation in the Panther Lake architecture, with both built on Intel's 3 nm process node. The Arc G3 is listed under the generation name "Arc G3 (Panther Lake)", while the Ultra 5 336H falls under "Ultra 5 (Panther Lake-H)". This distinction suggests a different segment within the same architectural family, but the core design principles remain consistent.

Both processors use 192 KB of L1 cache per core and 2.5 MB of L2 cache per core, along with 18 MB of shared L3 cache. The L1 and L2 cache capacities per core are identical, indicating the same core structure at the individual core level. The shared L3 pool is also the same size, so the main architectural divergence lies in the number of cores and the supporting I/O.

The Intel Arc G3 integrates the Arc B370 graphics solution, whereas the Intel Core Ultra 5 336H integrates Intel Xe3 Graphics. This represents a difference in the integrated GPU subsystem, with the Arc branding on the G3 indicating a different graphics tier compared to the Xe3 solution in the Ultra 5.

PCIe connectivity differs noticeably between the two. The Arc G3 provides Gen 5 with 4 lanes (CPU only), while the Ultra 5 336H provides Gen 5 with 12 lanes (CPU only). The Ultra 5 336H therefore has three times the PCIe lane count available for CPU-attached devices, which can affect expandability for high-bandwidth peripherals such as discrete GPUs or fast NVMe storage.

Memory support also separates the two. The Arc G3 supports only LPDDR5X, while the Ultra 5 336H supports both DDR5 and LPDDR5X. The memory bus is dual-channel for both, but the bandwidth figures differ: the Arc G3 reaches 136.5 GB/s, whereas the Ultra 5 336H reaches 115.2 GB/s. This means the Arc G3 has higher peak memory bandwidth despite a narrower memory type selection.

Neither processor supports ECC memory, and both have a locked multiplier. The production status for both is Active, and both are intended for mobile platforms. The release dates differ, with the Ultra 5 336H launching earlier on 2026-01-04 and the Arc G3 launching later on 2026-05-27.

Head-to-Head Benchmarks

The benchmark database contains a full set of measurements for the Intel Core Ultra 5 336H, while the Intel Arc G3 has no recorded benchmark scores. As a result, every head-to-head comparison is based on the Ultra 5 336H's recorded performance and its position relative to the broader CPU landscape.

In Cinebench R15, the Ultra 5 336H scores 2418 in multi-core and 341 in single-core. In Cinebench R20, the scores are 10076 multi-core and 1422 single-core. The Cinebench R23 results show 23991 multi-core and 3387 single-core. These numbers establish a consistent multi-threaded advantage for the Ultra 5 336H, which aligns with its 16-core, 16-thread configuration.

PassMark results for the Ultra 5 336H cover a wide range of workloads. Data compression scores 280340, data encryption scores 21291, and extended instructions score 24542. Floating point math reaches 82415, while integer math scores 62070. The find prime numbers test yields 299, and random string sorting scores 34402. The multi-thread score is 28545, physics scores 2682, and single-thread scores 4013.

The average benchmark score for the Ultra 5 336H is 34485. Its nearest rivals in the database include the Intel Core i7-13700HX with an average score of 34554, representing a delta of -0.2 percent relative to the Ultra 5 336H. The Intel Core i5-13450HX scores 34333, a delta of 0.4 percent. The AMD Ryzen 7 3700X scores 34260, a delta of 0.7 percent, and the AMD Ryzen AI 7 350 scores 34222, a delta of 0.8 percent. These deltas show that the Ultra 5 336H sits within 1 percent of four established desktop and mobile processors, indicating a tightly competitive performance band.

Because the Arc G3 has no benchmark entries in the database, no direct score comparisons can be drawn from recorded measurements. The database shows zero wins for the Arc G3 in head-to-head benchmark categories, and zero wins for the Ultra 5 336H in the same structured comparison, though the Ultra 5 336H has a full score profile while the Arc G3 does not.

The Verdict

The recorded data presents a clear situation: the Intel Core Ultra 5 336H is a fully measured processor with an 84th percentile ranking, an average benchmark score of 34485, and a complete suite of Cinebench and PassMark results. The Intel Arc G3 has no benchmark scores in the database, a 50th percentile ranking, and an average benchmark score of zero. Any selection between the two based on measured performance must therefore favor the Ultra 5 336H, because it has demonstrated results and the Arc G3 has none.

The Ultra 5 336H also offers more cores and threads, with 16 versus 14 for the Arc G3. The PCIe lane count favors the Ultra 5 336H as well, with 12 Gen 5 lanes versus 4 Gen 5 lanes. The Ultra 5 336H supports both DDR5 and LPDDR5X memory, while the Arc G3 supports only LPDDR5X, giving the Ultra 5 more flexibility in system configuration.

The Arc G3 does hold advantages in memory bandwidth, with 136.5 GB/s versus 115.2 GB/s for the Ultra 5 336H, and it integrates the Arc B370 graphics solution. The Arc G3 also has a later release date, which may indicate a newer product revision. For workloads that depend heavily on memory bandwidth, the Arc G3 could theoretically offer an edge, but without recorded benchmark data, that edge cannot be quantified.

Users seeking a processor with verified multi-core and single-core performance, a high percentile ranking, and broader memory and PCIe support should choose the Intel Core Ultra 5 336H. Users who prioritize the higher memory bandwidth and the Arc B370 integrated graphics of the Arc G3 may consider it, but the absence of benchmark data means its performance profile is unknown.

Specification Differences

The two processors differ in core count, with the Arc G3 offering 14 cores and the Ultra 5 336H offering 16 cores. Thread counts follow the same pattern, with 14 threads for the Arc G3 and 16 threads for the Ultra 5 336H. Both have identical base clocks of 1.90 GHz and boost clocks of 4.60 GHz.

Cache configurations are identical across both parts: 192 KB of L1 per core, 2.5 MB of L2 per core, and 18 MB of shared L3. The memory support differs, with the Arc G3 limited to LPDDR5X and the Ultra 5 336H supporting both DDR5 and LPDDR5X. Memory bandwidth is higher on the Arc G3 at 136.5 GB/s, while the Ultra 5 336H records 115.2 GB/s.

PCIe connectivity differs significantly. The Arc G3 provides Gen 5 with 4 lanes, while the Ultra 5 336H provides Gen 5 with 12 lanes. Integrated graphics differ as well, with the Arc G3 using Arc B370 and the Ultra 5 336H using Intel Xe3 Graphics.

The generation identifiers differ, with the Arc G3 listed as "Arc G3 (Panther Lake)" and the Ultra 5 336H listed as "Ultra 5 (Panther Lake-H)". The series field is null for the Arc G3, while the Ultra 5 336H belongs to the Core Ultra Series 3. Release dates differ, with the Ultra 5 336H released on 2026-01-04 and the Arc G3 released on 2026-05-27. Part numbers also differ, with the Arc G3 using SA4QZ and the Ultra 5 336H using SA4RD.

Where Each One Wins

The Intel Core Ultra 5 336H wins in every category with recorded benchmark data. Its Cinebench R23 multi-core score of 23991 and single-core score of 3387 demonstrate strong performance in both threaded and single-threaded workloads. The PassMark multi-thread score of 28545 and single-thread score of 4013 reinforce this pattern. The 84th percentile ranking places it above the vast majority of all CPUs in the database.

The Ultra 5 336H also wins on core count, offering 16 cores and 16 threads versus 14 for the Arc G3. This gives it a structural advantage in multi-threaded applications such as rendering, compilation, and data processing. The PCIe connectivity advantage of 12 Gen 5 lanes versus 4 Gen 5 lanes makes the Ultra 5 336H better suited for systems that need to attach multiple high-speed devices.

The Intel Arc G3 wins on memory bandwidth, with 136.5 GB/s versus 115.2 GB/s for the Ultra 5 336H. This could benefit memory-intensive workloads such as large data set manipulation or certain scientific computing tasks. The Arc G3 also integrates the Arc B370 graphics solution, which may offer different graphics capabilities compared to the Intel Xe3 Graphics in the Ultra 5 336H, though the database does not include graphics benchmark results for either part.

The Arc G3 has a later release date, suggesting a newer product introduction, but the database does not show any performance measurements for it. For users focused on measured performance, the Ultra 5 336H is the only option with data to support a decision. For users who value memory bandwidth and the specific Arc B370 integrated graphics, the Arc G3 presents a potential alternative, but its actual performance remains unverified in the database.
