Intel Arc G3 EXTREME vs Intel Core Ultra 5 235 Comparison

The Verdict

The benchmark data separates these two Intel parts into distinct roles. The Intel Arc G3 EXTREME is a mobile processor aimed at constrained power envelopes, while the Intel Core Ultra 5 235 is a desktop chip built for sustained throughput. The Arc G3 EXTREME wins 4 of the 17 head-to-head tests, all of them in the Cinebench R15 and R20 suites, with decisive margins. The Core Ultra 5 235 wins the remaining 13 tests, including the more modern Cinebench R23 workload and every PassMark test. The average benchmark score tells the same story: the Core Ultra 5 235 sits at 46062 with an 89th percentile ranking among all CPUs, while the Arc G3 EXTREME averages 36699 and ranks in the 85th percentile.

For users running legacy Cinebench R15 or R20 workloads, the Arc G3 EXTREME delivers a striking advantage. Its R15 multi-core score of 2192 beats the Core Ultra 5 235's 1488 by 47.3%, and its R20 multi-core score of 10945 beats 6202 by 76.5%. The single-core R20 result is similarly lopsided, with the Arc part scoring 1545 against 875, a 76.6% margin. Those results indicate the mobile chip's architecture executes those specific instruction patterns far more efficiently per clock.

The Core Ultra 5 235 dominates everywhere else. In Cinebench R23 multi-core, it scores 14769 against 14655, a modest 0.8% edge, but in single-core R23 it opens a 10.7% gap with 2085 versus 1862. PassMark results favor the desktop part by 18.9% to 33.2% across math, encryption, compression, and sorting workloads. The Core Ultra 5 235 also carries a higher launch MSRP of $257. The Arc G3 EXTREME has no recorded launch MSRP. Desktop builders with access to a Socket 1851 platform should choose the Core Ultra 5 235 for general productivity. Mobile users or those building around the BGA 2540 socket get the Arc G3 EXTREME, which trades overall throughput for exceptional legacy Cinebench performance and a 25 W TDP against the desktop part's 65 W TDP.

Architecture Differences

Both processors use a 3 nm process, but the similarities end there. The Arc G3 EXTREME uses the Panther Lake codename with the Arc G3 (Panther Lake) generation label, while the Core Ultra 5 235 uses the Arrow Lake architecture with the Arrow Lake-S codename and belongs to the Core Ultra Series 2 family. The Arc part is fabricated by Intel, and the Core Ultra 5 235 is fabricated by TSMC. The desktop chip has a stated transistor count of 17,800 million on a 243 mm² die; the mobile chip has no recorded transistor or die size data.

Both parts have 14 cores and 14 threads, so neither uses hyper-threading or simultaneous multi-threading. L1 cache is identical at 192 KB per core. L2 differs: the Arc G3 EXTREME has 2.5 MB per core, while the Core Ultra 5 235 has 3 MB per core. Shared L3 also differs, with 18 MB on the mobile part versus 24 MB on the desktop part. The larger caches on the Core Ultra 5 235 help explain its PassMark advantages, particularly in data compression and sorting tasks that benefit from larger working sets.

The memory subsystems diverge completely. The Arc G3 EXTREME supports LPDDR5X with a measured memory bandwidth of 136.5 GB/s over a dual-channel bus. The Core Ultra 5 235 supports DDR5 with 102.4 GB/s over dual-channel memory. Despite the lower peak bandwidth, the desktop part's PassMark results show no penalty in memory-sensitive tests. The mobile part's PCIe configuration is Gen 5 with 4 lanes (CPU only), while the desktop part has Gen 5 with 20 lanes (CPU only), giving the Socket 1851 chip far more expansion headroom. Integrated graphics also differ: the Arc G3 EXTREME carries an Arc B390 iGPU, and the Core Ultra 5 235 has Arc Xe-LPG Graphics 24EU. Neither supports ECC memory.

Head-to-Head Benchmarks

The Cinebench R15 and R20 results are the Arc G3 EXTREME's strongest territory. In R15 multi-core, the mobile part scores 2192 against 1488, a 47.3% win. R15 single-core shows 267 versus 210, a 27.1% margin. R20 multi-core widens to 10945 versus 6202, a 76.5% advantage, and R20 single-core reaches 1545 versus 875, a 76.6% margin. These are the only four tests the Arc part wins, and they are substantial wins, not narrow edges. The data indicates the Panther Lake architecture on the mobile part handles those older Cinebench instruction streams with exceptional efficiency, likely due to its higher per-core L2 bandwidth relative to its clock strategy.

The Core Ultra 5 235 reverses the trend in Cinebench R23. Multi-core scores are nearly identical, 14769 versus 14655, a 0.8% edge for the desktop part. Single-core R23 is a clearer victory, 2085 versus 1862, a 10.7% margin. The shift from R20 to R23 changes the instruction mix enough that the desktop part's higher boost clock of 5.00 GHz against 4.70 GHz becomes decisive.

PassMark results all favor the Core Ultra 5 235. Data compression shows 390711 versus 307094, a 21.4% win. Data encryption delivers 29293 versus 23881, an 18.5% edge. Extended instructions favor the desktop part by 26.7%, 32752 versus 24017. Prime number finding shows the largest relative gap at 33.2%, 371 versus 248. Floating point math scores 117951 versus 86929, a 26.3% margin. Integer math delivers 87948 versus 71164, a 19.1% edge. Multithread performance sits at 37816 versus 30659, an 18.9% win. Physics shows a narrow 2.1% margin, 2570 versus 2515. Random string sorting gives 48980 versus 37331, a 23.8% advantage. Single-thread performance is the closest PassMark result, 4516 versus 4293, a 4.9% edge for the desktop part.

Specification Differences

The two processors differ in every major specification except core count, thread count, L1 cache, memory bus width, ECC support, and multiplier lock. Both have 14 cores, 14 threads, 192 KB of L1 per core, dual-channel memory, no ECC, and are multiplier-unlocked. Base clock differs substantially: the Arc G3 EXTREME runs at 1.90 GHz, while the Core Ultra 5 235 runs at 3.40 GHz. Boost clock also differs, 4.70 GHz versus 5.00 GHz. TDP is a major differentiator, 25 W on the mobile part versus 65 W on the desktop part. The Arc part uses Intel BGA 2540, and the Core Ultra 5 235 uses Intel Socket 1851.

Cache sizes diverge at L2 and L3. The Arc G3 EXTREME has 2.5 MB per core L2 and 18 MB shared L3. The Core Ultra 5 235 has 3 MB per core L2 and 24 MB shared L3. Memory support differs by type and bandwidth: LPDDR5X at 136.5 GB/s on the mobile part, DDR5 at 102.4 GB/s on the desktop part. PCIe lanes differ by a factor of five, 4 lanes versus 20 lanes, both Gen 5. Integrated graphics differ as noted. The Core Ultra 5 235 has recorded transistor and die size figures, and the Arc G3 EXTREME does not. The desktop part has a recorded launch MSRP of $257, and the mobile part has none. Release dates also differ, with the Core Ultra 5 235 released earlier.

Where Each One Wins

The Arc G3 EXTREME wins exclusively in Cinebench R15 and R20 workloads. Its margins there are large enough to matter for anyone running those specific benchmark versions or similar legacy render workloads. The 76.6% single-core R20 advantage and 76.5% multi-core R20 advantage suggest the Panther Lake architecture extracts unusual performance from those instruction sequences, likely due to its LPDDR5X memory bandwidth and aggressive per-core L2 design. The 25 W TDP also makes it the only reasonable choice for compact mobile systems where power delivery and cooling are constrained.

The Core Ultra 5 235 wins everywhere else, and its wins cover the workloads that dominate everyday desktop use. PassMark integer math at 87948, floating point at 117951, and data compression at 390711 indicate strong general-purpose compute. The 20-lane Gen 5 PCIe connection suits desktop builds with discrete GPUs or NVMe storage. The 5.00 GHz boost clock and 24 MB shared L3 support single-thread responsiveness and larger cache-heavy tasks. Its Cinebench R23 results show it can hold its own in modern render workloads despite losing the R15 and R20 comparisons. The physics test is nearly a tie at 2570 versus 2515, a 2.1% margin, so neither part has a meaningful edge in that specific workload.

For a desktop builder, the Core Ultra 5 235 is the data-backed choice for general productivity, math-heavy tasks, and memory-intensive applications. For a mobile platform or a low-power build, the Arc G3 EXTREME offers a unique combination of a 25 W TDP and dominant legacy Cinebench scores, but it trails in the broader PassMark suite. The 4 versus 13 win split in head-to-head tests summarizes the trade-off: the Arc part excels in a narrow legacy niche, and the Core Ultra 5 235 delivers consistently higher throughput across the modern benchmark set.
