Analysis: Intel Arc G3 vs Intel Core Ultra 7 256V
The Verdict
The database comparison for the Intel Arc G3 and the Intel Core Ultra 7 256V is severely limited by the available information. The Intel Arc G3 (Panther Lake) has no recorded benchmark scores, no average performance score, and no nearest rival data. Its percentile ranking among all CPUs is 50, while the Intel Core Ultra 7 256V (Lunar Lake) holds a 75th percentile ranking. The data shows a clear distinction: the Core Ultra 7 256V is a measured, active mobile processor with a substantial benchmark profile, while the Arc G3 is listed as active but has no performance measurements in the database.
For any workload where performance data exists, the Intel Core Ultra 7 256V is the only option that can be evaluated. The Arc G3, with its 14 cores, 14 threads, and higher 25 W TDP, presents a theoretical configuration that suggests higher multi-threaded capacity, but the database contains no scores to confirm this. The Core Ultra 7 256V, with 8 cores and 8 threads at 17 W, delivers confirmed results across Cinebench, Geekbench, and Passmark suites. Buyers seeking verified performance should select the Core Ultra 7 256V. The Arc G3 remains an unverified entry, and no data supports any performance advantage for it at this time.
Where Each One Wins
The Intel Core Ultra 7 256V wins in every category where data exists. Its benchmark suite includes 19 recorded scores across multiple test families. In Cinebench R23 multi-core, it records 10399 points. In Geekbench multi-core, it records 8643 points. The Passmark multi-thread test shows 19530 points, and Passmark single-thread shows 4029 points. The Core Ultra 7 256V also delivers strong specialized results: Passmark data compression at 184985, Passmark floating point math at 58576, and Passmark integer math at 43358.
The Intel Arc G3 has no recorded wins because it has no recorded benchmarks. The database lists zero benchmark entries for the Arc G3, and the head-to-head comparison shows zero wins for both parts. The Arc G3 does have architectural advantages in the specification sheet: 14 cores versus 8 cores, and 18 MB of shared L3 cache versus 12 MB. It also lists a higher 4.60 GHz boost clock versus the Core Ultra 7's 4.80 GHz, which is actually lower. The Arc G3's higher core count suggests it could win in heavily threaded workloads, but the data cannot confirm this.
The Core Ultra 7 256V also holds the advantage in process node transparency. Both processors use a 3 nm process, but the Core Ultra 7 256V identifies TSMC as its foundry, while the Arc G3 lists Intel as its foundry. The Core Ultra 7 256V has a release date of September 2024, while the Arc G3 has a release date of May 2026, giving the older part a maturity advantage in measured results.
Architecture Differences
The two processors come from different Intel lineups, and the architecture differences are substantial. The Intel Arc G3 is part of the Arc G3 generation under the Panther Lake codename. The Intel Core Ultra 7 256V is part of the Core Ultra Series 2, using the Lunar Lake architecture. Both use a 3 nm process node, but the foundry differs: the Arc G3 uses Intel as its foundry, while the Core Ultra 7 256V uses TSMC.
Core and thread counts differ significantly. The Arc G3 has 14 cores and 14 threads, meaning no simultaneous multithreading. The Core Ultra 7 256V has 8 cores and 8 threads, also without multithreading. The Arc G3 has a base clock of 1.90 GHz and a boost clock of 4.60 GHz. The Core Ultra 7 256V has a base clock of 2.20 GHz and a boost clock of 4.80 GHz, giving it a higher frequency range in both metrics.
Cache hierarchies show a mixed picture. Both processors have 192 KB of L1 cache per core and 2.5 MB of L2 cache per core. The L3 cache differs: the Arc G3 has 18 MB shared, while the Core Ultra 7 256V has 12 MB shared. The Arc G3's larger L3 cache, combined with its higher core count, suggests better performance in cache-sensitive workloads.
Memory support also differs. The Arc G3 supports LPDDR5X memory with dual-channel configuration and a memory bandwidth of 136.5 GB/s. The Core Ultra 7 256V lists memory support as dependent on the motherboard, with dual-channel configuration but no bandwidth figure recorded. Both parts support PCIe Gen 5 with 4 lanes for CPU only, and neither supports ECC memory. Both processors have integrated graphics: the Arc G3 uses Arc B370, while the Core Ultra 7 256V uses Arc 140V. Both use mobile sockets, but they differ: the Arc G3 uses Intel BGA 2540, while the Core Ultra 7 256V uses Intel BGA 2833. Neither processor has an unlocked multiplier, and neither has a launch MSRP recorded in the database.

Head-to-Head Benchmarks
The head-to-head benchmark table in the database is empty, and the wins counter shows zero for both processors. This means no direct comparison can be made between the Intel Arc G3 and the Intel Core Ultra 7 256V based on benchmark results. The Arc G3 simply has no measured performance data.
The Core Ultra 7 256V does have a full benchmark profile that establishes its performance level. In Cinebench R23 multi-core, it scores 10399 points, and in single-core, it scores 1877.5 points. Geekbench results show 8643 points multi-core and 1990 points single-core. The Passmark suite provides extensive data: multi-thread at 19530, single-thread at 4029, floating point math at 58576, integer math at 43358, and prime numbers at 192. Data compression scores 184985, data encryption scores 13998, extended instructions score 15643, and random string sorting scores 22481. Physics scores 1595.
The Core Ultra 7 256V's average benchmark score is 21112, with a 75th percentile ranking among all CPUs. Its nearest rivals show a tight grouping: the AMD Ryzen 5 7530U has an average score of 21133, a delta of -0.1 percent relative to the Core Ultra 7 256V. The AMD Ryzen 5 5600G scores 21088, a delta of 0.1 percent. The Intel Core i3-1220P scores 21066, a delta of 0.2 percent. The Intel Core Ultra 7 155U scores 21174, a delta of -0.3 percent. These results indicate the Core Ultra 7 256V sits in a competitive cluster where the four nearest rivals are all within 0.3 percent of its average score.
The absence of Arc G3 data means the largest win in this comparison belongs to the Core Ultra 7 256V by default: it is the only processor with any recorded performance. The Arc G3's 50th percentile ranking, based on no benchmark scores, places it below the Core Ultra 7 256V's 75th percentile. The Core Ultra 7 256V also delivers these results at a lower TDP of 17 W versus the Arc G3's 25 W, and it was released earlier in September 2024 versus May 2026 for the Arc G3. The data confirms the Core Ultra 7 256V as the measured performer, while the Arc G3 remains a specification-only entry with no verified results.
