Intel Arc G3 vs Intel Core Ultra 7 265K Comparison

Where Each One Wins

The Intel Arc G3 and the Intel Core Ultra 7 265K occupy different corners of the performance spectrum. The Arc G3 is a mobile processor with a modest 14 cores and 14 threads, a 1.90 GHz base clock, and a 4.60 GHz boost clock. The Core Ultra 7 265K is a desktop part with 20 cores and 20 threads, a 3.90 GHz base clock, and a 5.50 GHz boost clock. The benchmark database contains no recorded benchmark scores for the Arc G3, while the Core Ultra 7 265K holds a substantial set of results across Cinebench, Geekbench, and Passmark tests.

The Core Ultra 7 265K delivers the only measurable wins in every workload category present in the database. It records a Cinebench R23 multicore score of 35850, a Geekbench multicore score of 23085, and a Passmark multithread score of 58594. The Arc G3 has no entries in these tests, so the desktop chip takes every available comparison by default. The data indicates that the Core Ultra 7 265K also wins on single-thread performance, posting a Cinebench R23 single-core score of 2020 and a Passmark single-thread score of 4928. In the absence of any Arc G3 benchmark records, the use-case split is straightforward: the Core Ultra 7 265K covers all measured computing tasks, while the Arc G3 has no recorded performance data to evaluate.

For workloads involving data compression, encryption, extended instructions, prime number search, floating point math, integer math, physics, and random string sorting, the Core Ultra 7 265K again stands alone with recorded scores. Its Passmark data compression result of 665554 and floating point math result of 189629 indicate strong throughput in these areas. The Arc G3, by contrast, offers no comparable figures. The database shows the Core Ultra 7 265K at the 94th percentile among all CPUs, whereas the Arc G3 sits at the 50th percentile with an average benchmark score of zero.

Architecture Differences

The two processors share a 3 nm process node, but they diverge sharply in nearly every other architectural detail. The Arc G3 is built by Intel, uses the Panther Lake codename, and is fabricated at Intel foundries. The Core Ultra 7 265K uses the Arrow Lake architecture, specifically Arrow Lake-S, and is fabricated at TSMC. The Arc G3 belongs to the Arc G3 (Panther Lake) generation, while the Core Ultra 7 265K belongs to the Ultra 7 (Arrow Lake) generation within the Core Ultra Series 2 product line.

Core and thread counts differ significantly. The Arc G3 has 14 cores and 14 threads, indicating no hyperthreading support. The Core Ultra 7 265K has 20 cores and 20 threads, also without hyperthreading, but with six additional physical cores. Clock speeds follow a similar pattern: the Arc G3 runs at 1.90 GHz base and 4.60 GHz boost, while the Core Ultra 7 265K runs at 3.90 GHz base and 5.50 GHz boost. The desktop chip has a 2.00 GHz advantage at base and a 0.90 GHz advantage at boost.

Cache configurations differ in the L2 and L3 levels. Both parts list 192 KB of L1 cache per core. The Arc G3 has 2.5 MB of L2 per core and 18 MB of shared L3. The Core Ultra 7 265K has 3 MB of L2 per core and 30 MB of shared L3. The desktop chip therefore carries more L2 per core and 12 MB more L3 capacity. The Core Ultra 7 265K also lists 17,800 million transistors on a 243 mm² die, while the Arc G3 has no transistor or die size figures recorded.

Memory support and platform features separate the two clearly. The Arc G3 uses LPDDR5X memory with dual-channel support and a memory bandwidth of 136.5 GB/s. The Core Ultra 7 265K uses DDR5 memory with dual-channel support and a memory bandwidth of 102.4 GB/s. The mobile part has higher bandwidth despite the lower platform power class. The Core Ultra 7 265K supports ECC memory; the Arc G3 does not. PCIe connectivity also differs: the Arc G3 provides Gen 5 with 4 lanes (CPU only), while the Core Ultra 7 265K provides Gen 5 with 20 lanes (CPU only). The desktop chip has five times the PCIe lane count.

The integrated graphics are different. The Arc G3 includes Arc B370 graphics, while the Core Ultra 7 265K includes Arc Xe-LPG Graphics 64EU. The Arc G3 uses the Intel BGA 2540 socket and targets the mobile market segment. The Core Ultra 7 265K uses Intel Socket 1851 and targets the desktop market segment. The Arc G3 has a locked multiplier; the Core Ultra 7 265K has an unlocked multiplier. The Core Ultra 7 265K has a launch MSRP of $394, while the Arc G3 has no launch MSRP recorded.

Head-to-Head Benchmarks

The head-to-head benchmark set in the database is empty, so no direct per-test comparisons exist between the Arc G3 and the Core Ultra 7 265K. The available evidence comes entirely from the Core Ultra 7 265K's standalone benchmark records and the Arc G3's absence of records. The Core Ultra 7 265K shows its strongest results in Cinebench R23 multicore with a score of 35850, Cinebench R20 multicore with 20918, and Geekbench multicore with 23085. These figures place it in the 94th percentile overall, with an average benchmark score of 70879.

The nearest rivals in the database provide context for the Core Ultra 7 265K's standing. The Intel Xeon 6511P records an average score of 71051, which is 0.2% higher than the Core Ultra 7 265K. The Intel Xeon Platinum 8270 records 71370, which is 0.7% higher. The Intel Core i7-14700KF records 70163, which is 1% lower. The AMD Ryzen 7 9700F records 69996, which is 1.3% lower. The Core Ultra 7 265K therefore sits within a tight band around its closest server and desktop rivals, slightly below two Xeon parts and slightly above one Core i7 and one Ryzen part.

In single-thread workloads, the Core Ultra 7 265K posts a Cinebench R15 single-core score of 708, a Cinebench R20 single-core score of 2953, a Cinebench R23 single-core score of 2020, and a Geekbench single-core score of 2713. The Passmark single-thread score of 4928 repeats as Passmark singlethread, confirming consistency. In multithread workloads, the Cinebench R15 multicore score of 5020 and the Passmark multithread score of 58594 round out the picture. The Arc G3 has no such records, so the data cannot support any claim of parity or superiority for the mobile part.

The Verdict

The recorded data points to the Intel Core Ultra 7 265K as the only processor in this comparison with measurable performance. It holds the 94th percentile rank among all CPUs, while the Arc G3 sits at the 50th percentile with an average benchmark score of zero. The Core Ultra 7 265K offers 20 cores, a 5.50 GHz boost clock, 30 MB of shared L3 cache, ECC memory support, 20 PCIe Gen 5 lanes, and an unlocked multiplier. The Arc G3 offers 14 cores, a 4.60 GHz boost clock, 18 MB of shared L3 cache, no ECC support, 4 PCIe Gen 5 lanes, and a locked multiplier. On every measurable axis in the database, the desktop part leads.

The Arc G3 does carry advantages in specific platform features. It has higher memory bandwidth at 136.5 GB/s compared to 102.4 GB/s, and it uses LPDDR5X memory, which is typical for mobile designs. Its 25 TDP class indicates a low-power profile, while the Core Ultra 7 265K has a 125 TDP. The Arc G3's 3 nm process from Intel matches the Core Ultra 7 265K's 3 nm process from TSMC in node size. These factors make the Arc G3 suitable for mobile contexts, but the database contains no benchmark results to quantify its performance.

For users choosing between the two, the Core Ultra 7 265K is the only part with verified scores. The desktop chip delivers strong results across rendering, general computing, and specialized math workloads, with an average benchmark score of 70879. The Arc G3 has no recorded scores and no nearest rivals listed, so no performance context exists. The verdict follows the data: the Core Ultra 7 265K is the choice for measured performance, while the Arc G3 remains an unquantified mobile option with lower core count, lower clocks, and less cache.
