Intel Arc G3 vs Intel Core Ultra 7 265H Comparison

Head-to-Head Benchmarks

The benchmark database currently contains no recorded head-to-head benchmark results for the Intel Arc G3, as its benchmark suite is empty. The Intel Core Ultra 7 265H, by contrast, has a full set of recorded measurements across Cinebench and Passmark tests. This means the only quantitative comparisons possible are between the Ultra 7 265H's scores and the nearest rival CPUs listed in the database, not against the Arc G3 directly.

The Core Ultra 7 265H delivers a Cinebench R23 multicore score of 19940 and a single-core score of 2080. In Cinebench R20, it records 12131 multicore and 1712 single-core. The R15 results show 2989 multicore and 307 single-core. These figures place the processor at the 88th percentile among all CPUs in the database, with an average benchmark score of 41621.

Against its nearest rivals, the Ultra 7 265H is essentially tied with the Intel Core 7 251TE, which scores 41650 on average, a delta of -0.1%. The Intel Core i7-14650HX sits at 41576, putting the Ultra 7 265H ahead by 0.1%. The Intel Core i7-12850HX scores 41779, meaning the Ultra 7 265H trails by 0.4%. The AMD Ryzen 9 5900X records 41376, with the Ultra 7 265H ahead by 0.6%. The data shows a tightly clustered group of competitors, with the Ultra 7 265H holding a marginal edge over two of the four rivals and a negligible deficit to the other two.

In Passmark testing, the Ultra 7 265H achieves 34027 in multithread, 4334 in single-thread, 109123 in floating point math, and 85479 in integer math. Data compression scores 334711, while encryption reaches 26005. Extended instructions hit 26805, physics scores 2497, and random string sorting records 40742. Prime number finding is the weakest result at 335. The average benchmark score of 41621 confirms that the Ultra 7 265H is a high-performing mobile part, but without any Arc G3 benchmark entries, the database cannot support a direct performance comparison between the two processors.

Architecture Differences

The Intel Arc G3 uses the Panther Lake codename and belongs to the Arc G3 generation. It is built on a 3 nm process node at Intel's foundry. The Intel Core Ultra 7 265H uses the Arrow Lake-H codename and belongs to the Core Ultra Series 2 generation. It also uses a 3 nm process node, but the foundry is TSMC. Both processors are actively produced for the mobile market segment.

The Arc G3 has 14 cores and 14 threads, while the Ultra 7 265H has 16 cores and 16 threads. Neither processor supports hyperthreading, as thread counts match core counts exactly. The Arc G3 has a base clock of 1.90 GHz and a boost clock of 4.60 GHz. The Ultra 7 265H runs higher, with a base clock of 2.20 GHz and a boost clock of 5.30 GHz. The Ultra 7 265H also has a higher thermal design power at 28, compared to the Arc G3's 25.

Cache configurations differ notably. The Arc G3 has 192 KB of L1 cache per core, 2.5 MB of L2 per core, and 18 MB of shared L3 cache. The Ultra 7 265H matches the L1 at 192 KB per core but has 3 MB of L2 per core and 24 MB of shared L3. The larger L2 and L3 caches on the Ultra 7 265H give it a structural advantage for workloads that benefit from larger working sets.

Memory support also separates the two. The Arc G3 supports only LPDDR5X in a dual-channel configuration, with a memory bandwidth of 136.5 GB/s. The Ultra 7 265H supports both DDR5 and LPDDR5X, also dual-channel, but its memory bandwidth is lower at 102.4 GB/s. The Arc G3 does not support ECC memory, while the Ultra 7 265H does. PCIe connectivity differs as well: the Arc G3 provides Gen 5 with 4 lanes (CPU only), while the Ultra 7 265H provides Gen 5 with 8 lanes (CPU only).

The integrated graphics are distinct. The Arc G3 pairs with Arc B370 graphics, while the Ultra 7 265H includes Arc Graphics 140T. The sockets also differ: the Arc G3 uses Intel BGA 2540, and the Ultra 7 265H uses Intel BGA 2049. The part numbers are SA4QZ for the Arc G3 and SRQAQ for the Ultra 7 265H. Neither processor has an unlocked multiplier.

Where Each One Wins

The data does not support a direct win breakdown between the two processors, since the Arc G3 has zero recorded benchmarks and the head-to-head table is empty. The wins counter shows 0 for both sides. The only basis for use-case analysis comes from the Ultra 7 265H's own benchmark results and the architectural specifications of the Arc G3.

For the Ultra 7 265H, the recorded scores indicate strength in multi-threaded productivity. The Cinebench R23 multicore score of 19940 and Passmark multithread score of 34027 show that 16 cores and 16 threads handle parallel workloads effectively. The single-core score of 2080 in Cinebench R23 and 4334 in Passmark single-thread indicate solid responsiveness for lightly threaded tasks. The floating point math score of 109123 suggests good capability for scientific or simulation workloads. Data compression at 334711 and encryption at 26005 point to competent performance in file archiving and security-related operations.

The Arc G3, based on its specifications, has fewer cores (14 vs 16) and lower clocks (1.90 GHz base, 4.60 GHz boost vs 2.20 GHz base, 5.30 GHz boost). Its memory bandwidth is higher at 136.5 GB/s, which could benefit memory-intensive tasks, but its smaller L3 cache (18 MB vs 24 MB) may limit some workloads. The Arc G3's integrated graphics are the Arc B370, which by name suggests a distinct graphics solution, but the database provides no benchmark scores to evaluate its capability. The Ultra 7 265H's Arc Graphics 140T similarly lacks benchmark data in the pack.

The practical interpretation: the Ultra 7 265H is the only one of the two with any recorded performance evidence, and that evidence shows a high-percentile mobile CPU. The Arc G3 is a newer release (2026-05-27 vs 2025-01-12) with a different architecture, but without measurements, the database cannot confirm any workload-specific advantage for it.

The Verdict

The database contains no benchmark scores for the Intel Arc G3, which means any claim of performance superiority for it would lack evidentiary support. The Intel Core Ultra 7 265H, however, has a comprehensive set of recorded measurements that place it at the 88th percentile of all CPUs, with an average benchmark score of 41621. This is a strong showing, particularly given that its nearest rivals (the Intel Core 7 251TE, Intel Core i7-14650HX, Intel Core i7-12850HX, and AMD Ryzen 9 5900X) all fall within a 1% band around its average score.

For a builder choosing between these two mobile processors, the Ultra 7 265H is the only option with measurable performance data. Its 16 cores, higher clocks, larger caches, and support for both DDR5 and LPDDR5X memory give it a clear specification advantage on paper. The Arc G3 counters with higher memory bandwidth (136.5 GB/s vs 102.4 GB/s) and a newer release date, but these factors do not translate into recorded benchmark wins.

The Ultra 7 265H is the safer selection based on available evidence. Its Cinebench R23 multicore score of 19940 and Passmark multithread score of 34027 indicate strong parallel processing capability. The single-core score of 2080 in R23 confirms responsive single-thread performance. The Arc G3 remains a speculative choice: it is a Panther Lake part on Intel's 3 nm process, but without database measurements, its real-world behavior is unverified.

The verdict from the data: choose the Core Ultra 7 265H if measured performance matters. Choose the Arc G3 only if the specific architectural features (higher memory bandwidth, newer process generation, distinct integrated graphics) align with a workload that those specifications would plausibly benefit, and accept that no benchmark evidence currently supports that choice.
