Intel Arc G3 vs Intel Core Ultra 5 338H Comparison

Head-to-Head Benchmarks

The Intel Core Ultra 5 338H enters the database with a complete benchmark suite, while the Intel Arc G3 currently has no recorded benchmark scores. This makes a direct numerical comparison impossible for most tests, but the available data for the Core Ultra 5 338H allows for a clear characterization of its performance profile.

The Core Ultra 5 338H posts an average benchmark score of 33989, placing it at the 84th percentile among all CPUs in the database. Its nearest rivals show how tightly grouped this performance tier is: the Intel Core Ultra 7 165H scores 34083, which is 0.3% higher, and the Intel Core i7-12800HX scores 33875, which is 0.3% lower. The AMD EPYC 4244P sits 0.7% higher at 34220, and the Intel Xeon 6353P sits 0.4% lower at 33844. These deltas are small enough that the Core Ultra 5 338H effectively trades blows with all four rivals within a one-percent band.

In Cinebench R23 multicore, the Core Ultra 5 338H records 16331 points. Its single-core score in the same test is 2044 points. Cinebench R20 results are 10213 multicore and 1441 single-core. Cinebench R15 shows 2504 multicore and 305 single-core. These results indicate a processor that scales well across rendering workloads, with the multicore scores representing a substantial multiple of the single-core figures.

PassMark results for the Core Ultra 5 338H cover a range of workloads. The multithread score is 28717, and the single-thread score is 4180. Floating point math reaches 84067, while integer math reaches 64934. Data compression scores 276539, and data encryption scores 21367. Extended instructions produce 23906, and random string sorting produces 34082. Physics simulation scores 2697, and prime number finding scores 304.

Because the Arc G3 has no benchmark entries, the head-to-head comparison is one-sided. The data shows the Core Ultra 5 338H as the only measured part in this pairing. The Arc G3 lacks recorded scores for every test in the database, meaning its performance class cannot be established from measurements.

Where Each One Wins

The Core Ultra 5 338H wins every benchmark category by default, since it is the only one of the two with recorded data. Its strengths are visible across both synthetic rendering and real-world workload simulations.

In rendering workloads, the Cinebench R23 multicore score of 16331 indicates strong sustained throughput for CPU-bound tasks. The single-core score of 2044 shows capable per-thread performance. The R20 and R15 results follow the same pattern, with multicore scores of 10213 and 2504 respectively, and single-core scores of 1441 and 305.

In PassMark tests, the Core Ultra 5 338H shows particular strength in data compression at 276539, which is the highest single score in its suite. Floating point math at 84067 and integer math at 64934 both indicate robust arithmetic throughput. The multithread score of 28717 confirms that the processor uses its 12 threads effectively across parallel workloads.

The Arc G3 has no wins in any category because no benchmark data exists for it. Its 14 cores and 14 threads suggest potential for multithreaded workloads, but the database contains no measurements to confirm or refute that potential.

Architecture Differences

Both processors share the Panther Lake codename and the 3 nm process node from Intel. They also share the same foundry, with Intel listed for both. The Arc G3 is labeled as generation "Arc G3 (Panther Lake)", while the Core Ultra 5 338H is labeled as "Ultra 5 (Panther Lake-H)". This indicates the Core Ultra 5 338H belongs to the H-series variant of Panther Lake, while the Arc G3 appears as a distinct product line within the same architecture family.

The integrated graphics are identical on paper: both use the Arc B370. The memory support is also identical, with both supporting LPDDR5X over a dual-channel bus at 136.5 GB/s. Neither supports ECC memory, and both use the same PCIe configuration of Gen 5 with 4 lanes for the CPU only.

The release dates differ. The Core Ultra 5 338H was released on 2026-01-04, while the Arc G3 was released later on 2026-05-27. Both are listed as active production parts with a mobile market segment.

Specification Differences

The core and thread counts are the primary differentiator. The Arc G3 has 14 cores and 14 threads, while the Core Ultra 5 338H has 12 cores and 12 threads. Neither uses simultaneous multithreading, as each core corresponds to exactly one thread in both parts.

The boost clock differs slightly. The Arc G3 boosts to 4.60 GHz, while the Core Ultra 5 338H boosts to 4.70 GHz. Both have the same base clock of 1.90 GHz and the same TDP of 25 watts.

The cache hierarchy is identical between the two. Both have 192 KB of L1 cache per core, 2.5 MB of L2 cache per core, and 18 MB of shared L3 cache.

The socket is the same for both: Intel BGA 2540. Neither has an unlocked multiplier, so overclocking is not supported according to the data.

The part numbers differ, with the Arc G3 listed as SA4QZ and the Core Ultra 5 338H listed as SA4REQ9EW. No launch MSRP is recorded for either part.

The Verdict

The data presents an unusual comparison. The Core Ultra 5 338H has a full benchmark suite with an average score of 33989 and an 84th percentile ranking. The Arc G3 has no recorded benchmarks at all, leaving its performance entirely unmeasured.

For users selecting between these two, the Core Ultra 5 338H offers measured performance across rendering, encryption, compression, and arithmetic workloads. Its Cinebench R23 multicore score of 16331 and single-core score of 2044 provide concrete reference points. Its PassMark multithread score of 28717 and single-thread score of 4180 further define its capabilities.

The Arc G3 offers two additional cores and two additional threads over the Core Ultra 5 338H, which could benefit heavily parallel workloads. However, the database contains no scores to verify this. Its boost clock is 0.10 GHz lower, and its release date is later. All other specifications, including cache, memory support, integrated graphics, TDP, and process node, are identical.

The verdict from the recorded data is straightforward: the Core Ultra 5 338H is the only part in this pairing with measurable performance. The Arc G3 may hold potential in multithreaded scenarios given its 14 cores, but the absence of benchmark results means no performance claim can be made for it. The Core Ultra 5 338H, with its 84th percentile ranking and tight grouping against its nearest rivals, is the processor with demonstrated capabilities. The Arc G3 remains an unmeasured quantity in the database.
