Intel Arc G3 vs Intel Core Ultra 5 250K Plus Comparison

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark results between the Intel Arc G3 and the Intel Core Ultra 5 250K Plus. The Arc G3 has no recorded benchmark scores, while the Ultra 5 250K Plus has a full suite of Cinebench and PassMark results. This means all performance comparisons must be inferred from the available data on the Ultra 5 250K Plus and the architectural differences between the two processors.

The Ultra 5 250K Plus delivers strong multi-core performance in Cinebench tests. Its Cinebench R23 multi-core score of 30867 places it in the 93rd percentile among all CPUs in the database. The single-core score of 2261 in the same test indicates solid per-thread performance. In Cinebench R20, the chip scores 18442 multi-core and 2603 single-core, while in Cinebench R15 it achieves 4640 multi-core and 328 single-core. These scores show a consistent scaling pattern across different Cinebench versions.

PassMark results for the Ultra 5 250K Plus reveal specific strengths. The data compression score of 568721 is particularly high, and the floating point math score of 162692 confirms strong arithmetic throughput. Integer math reaches 125091, while extended instructions hit 44565. The multithread score of 51596 and single-thread score of 4757 both contribute to the overall average benchmark score of 66855. The processor ranks in the 93rd percentile against all CPUs in the database.

The nearest rivals for the Ultra 5 250K Plus provide context for its standing. The AMD EPYC 4465P averages 66925, which is 0.1% higher. The Intel Xeon 6515P averages 67006, 0.2% higher.

Architecture Differences

The two processors come from different Intel lines and use different foundries. The Arc G3 uses the Panther Lake codename with a 3 nm process node fabricated by Intel. The Ultra 5 250K Plus uses the Arrow Lake Refresh codename, also on a 3 nm node, but fabricated by TSMC. This foundry difference is significant for manufacturing characteristics, though the database does not provide direct performance implications.

Core configurations differ substantially. The Arc G3 has 14 cores and 14 threads, meaning no hyperthreading or similar technology is in use. The Ultra 5 250K Plus has 18 cores and 18 threads, also without additional threading per core. Both processors have 192 KB of L1 cache per core. The L2 cache differs, with the Arc G3 offering 2.5 MB per core and the Ultra 5 250K Plus offering 3 MB per core. The L3 cache shows a larger gap: the Arc G3 has 18 MB shared, while the Ultra 5 250K Plus has 30 MB shared.

Integrated graphics differentiate the two. The Arc G3 includes an Arc B370 integrated GPU, while the Ultra 5 250K Plus uses Arc Xe-LPG Graphics with 64 execution units. The database does not provide benchmark scores for either integrated solution, so no performance comparison is possible.

The memory controllers differ in type and bandwidth. The Arc G3 uses LPDDR5X with 136.5 GB/s bandwidth, which is higher than the Ultra 5 250K Plus's DDR5 at 115.2 GB/s. Both use dual-channel configurations. ECC support is present only on the Ultra 5 250K Plus.

PCIe connectivity varies significantly. The Arc G3 provides Gen 5 with 4 lanes for CPU-only use. The Ultra 5 250K Plus provides Gen 5 with 20 lanes for CPU-only use. This is a major difference in expansion capability.

The Ultra 5 250K Plus has documented physical characteristics: 17,800 million transistors and a die size of 243 mm². The Arc G3 has no recorded transistor count or die size in the database.

Where Each One Wins

The Intel Core Ultra 5 250K Plus wins decisively in all recorded benchmark categories. It has a 93rd percentile ranking among all CPUs, with an average benchmark score of 66855. Its Cinebench R23 multi-core score of 30867 and single-core score of 2261 demonstrate strong performance in rendering workloads. PassMark results show particular strength in data compression at 568721 and floating point math at 162692. The processor also supports ECC memory, which matters for stability-sensitive workloads.

The Intel Arc G3 has no recorded wins in any benchmark category because no benchmark data exists. Its advantages are purely architectural and specification-based. The LPDDR5X memory support with 136.5 GB/s bandwidth exceeds the Ultra 5 250K Plus's DDR5 bandwidth of 115.2 GB/s. The 25-watt TDP makes it a low-power option suitable for mobile platforms. The Intel BGA 2540 socket confirms its mobile market segment. Its release date of May 27, 2026 is later than the Ultra 5 250K Plus's March 10, 2026 release.

The Ultra 5 250K Plus wins on core count, clock speeds, cache capacity, PCIe lane count, ECC support, and unlocked multiplier. It also has a documented transistor count and die size, which adds transparency to its design. The Arc G3 wins on memory bandwidth and power efficiency on paper, though no performance data confirms the practical impact of these specifications.

The Verdict

The data clearly favors the Intel Core Ultra 5 250K Plus for any measured performance scenario. It holds a 93rd percentile ranking with an average benchmark score of 66855, while the Arc G3 has no benchmark scores at all. The Ultra 5 250K Plus delivers 18 cores with a 5.30 GHz boost clock, 30 MB of L3 cache, and 20 PCIe Gen 5 lanes. Its Cinebench R23 multi-core score of 30867 and PassMark multithread score of 51596 establish it as a capable desktop processor. The nearest rivals, including the AMD EPYC 4465P and Intel Xeon 6515P, sit within one percentage point of its average score, confirming it competes at a high level.

The Arc G3 is a mobile processor with a 25-watt TDP and LPDDR5X memory support. Its 14 cores and 4.60 GHz boost clock are lower than the Ultra 5 250K Plus, but its memory bandwidth of 136.5 GB/s is higher. Without benchmark data, its real-world performance cannot be quantified. The database records no wins for the Arc G3 in any head-to-head comparison.

Users who need a desktop processor with strong multi-core and single-core performance should select the Intel Core Ultra 5 250K Plus. Its benchmark scores and 93rd percentile ranking speak directly to its capabilities. Users who require a mobile processor with low power consumption and high memory bandwidth may consider the Arc G3, but they must accept the absence of measured performance data. The two processors target different market segments, and the database supports the Ultra 5 250K Plus as the better-documented and higher-performing option.
