Architecture Differences

The Intel Arc G3 and the Intel Core Ultra 5 245KF represent two distinct design philosophies within Intel's lineup. The Arc G3 is a mobile-oriented processor built on the Panther Lake codename, while the Core Ultra 5 245KF is a desktop part based on the Arrow Lake architecture. Both share the same 3 nm process node, but the foundry differs: Intel fabricates the Arc G3, while TSMC produces the Core Ultra 5 245KF.

The cache hierarchy shows a notable difference in shared L3 capacity. The Arc G3 carries 18 MB of shared L3 cache, while the Core Ultra 5 245KF offers 24 MB. Per-core L1 cache is identical at 192 KB, but L2 cache differs: the Arc G3 has 2.5 MB per core, whereas the Core Ultra 5 245KF has 3 MB per core.

Memory support separates 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 5 245KF uses DDR5 memory, also dual-channel, but with a lower recorded memory bandwidth of 102.4 GB/s. Neither processor supports ECC memory.

PCIe connectivity also differs. The Arc G3 provides Gen 5 with 4 lanes (CPU only), which suits its mobile, power-constrained role. The Core Ultra 5 245KF provides Gen 5 with 20 lanes (CPU only), a far wider interface appropriate for a desktop platform with discrete GPUs and expansion devices.

The integrated graphics situation is a major architectural divergence. The Arc G3 includes an Arc B370 integrated GPU, while the Core Ultra 5 245KF has no integrated graphics at all, indicated as N/A. The Core Ultra 5 245KF compensates with an unlocked multiplier, allowing overclocking, whereas the Arc G3 has a locked multiplier.

The transistor count and die size are only recorded for the Core Ultra 5 245KF: 17,800 million transistors on a 243 mm² die. The Arc G3 lacks recorded values for these fields. The Core Ultra 5 245KF was released on 2024-10-23, while the Arc G3's release date is later, 2026-05-27. Both processors are currently marked as Active in production status.

The Verdict

The recorded data shows two processors aimed at entirely different market segments. The Intel Arc G3 is a Mobile segment processor with a 25 watt TDP, integrated Arc B370 graphics, and a BGA 2540 socket. The Intel Core Ultra 5 245KF is a Desktop segment processor with a 125 watt TDP, no integrated graphics, and an LGA 1851 socket.

The Core Ultra 5 245KF holds a significant performance advantage according to the database. Its average benchmark score is 55,093, placing it in the 91st percentile of all CPUs. The Arc G3 has an average benchmark score of 0 in the database, with no recorded benchmark results, and sits at the 50th percentile. The Core Ultra 5 245KF also has a recorded launch MSRP of $294.

For workloads requiring high multi-core throughput, the Core Ultra 5 245KF is the clear choice based on its extensive benchmark suite. The Arc G3, with no recorded benchmarks, cannot be evaluated for performance in the same manner. The Arc G3 may be suited for systems where integrated graphics are necessary and power draw is limited to 25 watts. The Core Ultra 5 245KF, with its unlocked multiplier and 20 PCIe Gen 5 lanes, targets desktop users who plan to pair it with discrete graphics and overclock. The data indicates that the Core Ultra 5 245KF is the stronger performer, while the Arc G3 serves a niche mobile role with lower power and integrated graphics.

These narrow deltas indicate the Core Ultra 5 245KF sits in a tightly contested performance band.

The Arc G3's lack of recorded benchmarks means no direct performance comparison is possible from the database. Its 50th percentile ranking and zero average score reflect an absence of measurement data rather than a measured performance level. The Core Ultra 5 245KF's 91st percentile ranking places it well above the median across all CPUs in the database.

The wins count in the head-to-head section is 0 for both processors, confirming the absence of direct comparative tests. The Core Ultra 5 245KF's individual benchmark scores, however, provide a detailed performance profile. The Cinebench R23 multi-core score of 36,647 demonstrates strong sustained multi-threaded capability. The PassMark data compression score of 460,123 is particularly high, indicating efficient handling of compression workloads.

The Core Ultra 5 245KF's single-thread performance, as measured by Cinebench R23 at 5,173 and PassMark at 4,715, supports its position in the 91st percentile. Its floating point math score of 131,546 exceeds its integer math score of 98,854, suggesting a stronger vector processing capability. The physics score of 2,998 and prime number finding score of 416 round out the profile.

Without Arc G3 benchmarks, the only definitive comparisons come from specification differences. The Core Ultra 5 245KF holds higher clock speeds, more cache, wider PCIe connectivity, and an unlocked multiplier. The Arc G3 counters with lower power consumption, integrated graphics, and higher memory bandwidth. The database records no direct performance contest between the two, leaving the Core Ultra 5 245KF as the only one of the pair with measurable benchmark data.
