Intel Arc G3 vs Intel Core Ultra 5 235HX Comparison

The Verdict

The database currently contains comprehensive benchmark results for the Intel Core Ultra 5 235HX, while the Intel Arc G3 has no recorded benchmark scores, an average benchmark score of 0, and a percentile rank of 50. The Core Ultra 5 235HX, by contrast, holds a percentile rank of 91 and an average benchmark score of 52073. Any direct comparison must therefore rely entirely on the architectural specifications recorded for both processors, with performance conclusions drawn only from the measured data of the Ultra 5.

The Intel Core Ultra 5 235HX is the only one of the two with measured performance data, and that data positions it as a high-performing mobile processor. Its nearest rivals in the database include the AMD EPYC 8124P with an average score of 52121 and a delta of -0.1 percent, the AMD Ryzen 9 5950X with 51947 and a delta of 0.2 percent, the Intel Core i7-14700 with 52301 and a delta of -0.4 percent, and the Intel Core i9-13900F with 51730 and a delta of 0.7 percent. These deltas indicate that the Ultra 5 235HX sits within a narrow band of roughly one percent of these desktop-class processors, which is a notable result for a 55 watt mobile part.

For the Intel Arc G3, the absence of benchmark scores means that no performance verdict can be derived from measured data. The processor is listed as active in production with a 25 watt TDP, a 14-core, 14-thread configuration, and a Panther Lake codename on a 3 nm node. Its specifications suggest a lower-power mobile part, but without recorded scores, the database cannot confirm any performance relationship to the Ultra 5 235HX.

Architecture Differences

The two processors share the same core and thread count at 14 cores and 14 threads, but they diverge substantially in nearly every other architectural dimension. The Intel Arc G3 uses the Panther Lake codename and is fabricated on a 3 nm process at Intel, while the Intel Core Ultra 5 235HX uses the Arrow Lake-HX codename, part of the Core Ultra Series 2 generation, and is fabricated on a 3 nm process at TSMC. Both parts are mobile segments, but their sockets differ: the Arc G3 uses Intel BGA 2540, whereas the Ultra 5 235HX uses Intel BGA 2114.

Clock speeds favor the Ultra 5 235HX. The Arc G3 has a base clock of 1.90 GHz and a boost clock of 4.60 GHz. The Ultra 5 235HX has a base clock of 2.90 GHz and a boost clock of 5.10 GHz. That is a 1.00 GHz higher base clock and a 0.50 GHz higher boost clock for the Ultra 5. The power envelopes also differ significantly: the Arc G3 is rated at 25 watts, while the Ultra 5 235HX is rated at 55 watts. The Ultra 5 also has an unlocked multiplier, while the Arc G3 does not.

Cache hierarchies show clear differences. Both list 192 KB of L1 cache per core. The L2 cache is 2.5 MB per core on the Arc G3 versus 3 MB per core on the Ultra 5 235HX. Shared L3 cache is 18 MB on the Arc G3 and 24 MB on the Ultra 5. The Ultra 5 therefore has more L2 per core, more total L3, and a larger aggregate cache footprint.

Memory support differs in type and bandwidth. The Arc G3 supports LPDDR5X memory on a dual-channel bus with a recorded bandwidth of 136.5 GB/s. The Ultra 5 235HX supports DDR5 memory on a dual-channel bus with a recorded bandwidth of 102.4 GB/s. The Arc G3 has the higher memory bandwidth figure, while the Ultra 5 uses a more conventional DDR5 configuration. Neither supports ECC memory.

PCIe connectivity also diverges. The Arc G3 lists Gen 5 with 4 lanes, CPU only. The Ultra 5 235HX lists Gen 5 with 20 lanes, CPU only. The Ultra 5 has five times the CPU PCIe lane count, which matters for systems that need to attach multiple high-bandwidth devices directly to the processor.

Integrated graphics differ as well. The Arc G3 carries an Arc B370 iGPU, while the Ultra 5 235HX carries an Arc Xe-LPG Graphics 48EU solution. The transistor count and die size are recorded only for the Ultra 5: 17,800 million transistors on a 243 mm² die. No transistor count or die size is listed for the Arc G3. The Ultra 5 was released on 2025-01-12, while the Arc G3 has a later release date of 2026-05-27.

Where Each One Wins

The Intel Core Ultra 5 235HX wins in every measured performance category because it is the only processor in this comparison with benchmark scores in the database. Its single-thread performance is recorded at 4683 in PassMark single-thread tests, with a Cinebench R23 single-core score of 4903. Its multi-thread performance reaches 40849 in PassMark multithread, 34731 in Cinebench R23 multicore, and 14587 in Cinebench R20 multicore. These scores indicate a processor that handles both lightly threaded and heavily threaded workloads with substantial headroom.

The Ultra 5 also records strong results in specialized PassMark subtests. Data compression scores 426417, data encryption scores 32697, extended instructions score 34808, find prime numbers scores 361, floating point math scores 129819, integer math scores 97177, physics scores 2550, and random string sorting scores 50929. The floating point and integer math results suggest a processor well suited to compute-heavy tasks, while the data compression and encryption numbers indicate solid throughput in data-centric operations.

The Intel Arc G3, with no benchmark scores, cannot be said to win in any measured category. Its architectural advantages are limited to memory bandwidth, where its LPDDR5X support and 136.5 GB/s figure exceed the Ultra 5's 102.4 GB/s, and its lower 25 watt TDP, which indicates a more power-efficient design target. The Arc G3 also has a smaller L3 cache at 18 MB versus 24 MB, which may influence latency-sensitive workloads, but no measured data confirms this.

The Ultra 5's unlocked multiplier is a distinguishing feature for systems where overclocking is permitted, while the Arc G3's locked multiplier restricts such adjustments. The Ultra 5's 20 PCIe Gen 5 lanes provide a clear expansion advantage over the Arc G3's 4 lanes. For workloads that depend on PCIe-attached accelerators or storage, the Ultra 5 has the structural advantage.

Head-to-Head Benchmarks

No head-to-head benchmark entries exist in the database for these two processors, and the Intel Arc G3 has no individual benchmark scores recorded at all. The comparison therefore rests on the Ultra 5's measured results and the architectural specifications of both parts.

The Intel Core Ultra 5 235HX produces a Cinebench R23 multicore score of 34731 and a single-core score of 4903. The ratio between these scores, roughly seven to one, indicates strong scaling across its 14 cores. In Cinebench R20, the multicore score is 14587 and the single-core score is 2059. In Cinebench R15, the multicore score is 3500 and the single-core score is 494. The progression across R15, R20, and R23 shows consistent single-thread gains as the workload scales, with the multicore results growing substantially in each newer test version.

PassMark results for the Ultra 5 show a single-thread score of 4683 and a multithread score of 40849. The multithread score is roughly 8.7 times the single-thread score, which reflects the processor's ability to utilize all 14 threads effectively. The integer math score of 97177 and floating point math score of 129819 indicate that floating point operations complete at a higher throughput than integer operations, a characteristic that aligns with the processor's architecture.

The nearest rival comparisons for the Ultra 5 place it within a tight performance cluster. The AMD EPYC 8124P scores 52121, which is only 0.1 percent above the Ultra 5's 52073. The AMD Ryzen 9 5950X scores 51947, which is 0.2 percent below. The Intel Core i7-14700 scores 52301, which is 0.4 percent above. The Intel Core i9-13900F scores 51730, which is 0.7 percent below. These deltas, all under one percent, show that the Ultra 5 235HX delivers performance comparable to established desktop processors from both AMD and Intel, despite being a mobile part with a 55 watt TDP.

The Arc G3's specifications suggest a different design point. Its 25 watt TDP is less than half that of the Ultra 5, and its 4.60 GHz boost clock is lower. Its memory bandwidth of 136.5 GB/s is higher than the Ultra 5's 102.4 GB/s, which may benefit memory-bound workloads if the processor's other characteristics allow them to scale. Its 14-core, 14-thread layout matches the Ultra 5, but its smaller 18 MB L3 cache and reduced PCIe lane count limit its expansion and caching capabilities relative to the Ultra 5.

The recorded data shows that the Ultra 5 235HX is a high-percentile mobile processor with measured results that rival desktop parts. The Arc G3, as a newer and lower-power design, has no measured data in the database, so any performance assessment of it must await benchmark results. The architectural records indicate that the two processors target different power and performance envelopes, with the Ultra 5 favoring higher clocks, more cache, more PCIe lanes, and an unlocked multiplier, while the Arc G3 favors lower power consumption and higher memory bandwidth.
