Intel Arc G3 vs Intel Core Ultra 5 245 Comparison

Where Each One Wins

The recorded data splits these two Intel processors cleanly by market intent. The Intel Arc G3, a mobile part on the Panther Lake platform, appears in the database with no benchmark entries, zero recorded scores, and a percentile rank of 50 among all CPUs. Its counterpart, the Intel Core Ultra 5 245, carries a full benchmark suite across Cinebench and PassMark tests, achieving a 90th percentile ranking and an average benchmark score of 48,995.

Because the Arc G3 has no recorded benchmarks, every measurable win belongs to the Core Ultra 5 245. The desktop chip delivers scores in every category where the mobile chip has no data: multi-core rendering, single-core rendering, integer math, floating-point math, encryption, compression, and physics simulation. The Arc G3 cannot claim a single benchmark victory in the database, as its wins counter sits at zero.

The functional split emerges from the specifications instead of raw scores. The Arc G3 targets mobile devices with a 25 W TDP, a dual-channel LPDDR5X memory bus delivering 136.5 GB/s bandwidth, and a PCIe Gen 5 interface limited to 4 CPU lanes. The Core Ultra 5 245 targets desktops with a 65 W TDP, dual-channel DDR5 memory at 102.4 GB/s, and a PCIe Gen 5 interface with 20 CPU lanes. The mobile part emphasizes power efficiency and memory bandwidth density for laptops, while the desktop part prioritizes expansion capacity and sustained compute throughput.

The Verdict

The data indicates that only one of these processors has measurable performance, and that processor is the Intel Core Ultra 5 245. Its benchmark suite shows consistent results across rendering and computational workloads, with a Cinebench R23 multi-core score of 32,924 and a single-core score of 4,648. The PassMark multi-thread score reaches 38,706, while the single-thread score sits at 4,394. These figures place the chip in the 90th percentile of all CPUs in the database, with an average score of 48,995.

The Intel Arc G3 remains an unquantified entity in the database. With no benchmarks recorded, no average score, and a 50th percentile ranking that reflects the absence of data rather than measured performance, any comparison must rely on architectural specifications alone. Users seeking a desktop processor with verified rendering and computation scores should select the Core Ultra 5 245. Users seeking a low-power mobile processor with integrated Arc B370 graphics and a 3 nm Panther Lake design should consider the Arc G3, but they will find no benchmark evidence in the database to validate its performance.

The Core Ultra 5 245 also carries a launch MSRP of $270, a figure stated once here for reference. The Arc G3 has no launch MSRP recorded. For desktop workloads with measurable outcomes, the Core Ultra 5 245 is the only choice supported by data.

Head-to-Head Benchmarks

The head-to-head benchmark array in the database is empty, confirming that no direct test pits these two processors against each other. However, the Core Ultra 5 245’s individual benchmark results provide a complete picture of its capabilities, and these can be interpreted against its nearest rivals.

In Cinebench R23 multi-core, the Core Ultra 5 245 scores 32,924. This is a strong result for a 14-core, 14-thread desktop chip with a 3.50 GHz base clock and 5.10 GHz boost clock. The single-core R23 score of 4,648 reflects the high boost frequency and the Arrow Lake architecture’s efficiency at moderate power levels. The R20 multi-core score of 13,828 and single-core score of 1,952 follow the same pattern, as does the R15 multi-core score of 3,318 and single-core score of 468.

PassMark results show the chip’s computational breadth. The multi-thread score of 38,706 pairs with a single-thread score of 4,394. Integer math reaches 91,187, while floating-point math hits 120,548. Extended instructions score 33,304, data encryption scores 30,236, and data compression scores 400,942. Random string sorting reaches 49,140, and prime number finding scores 365. Physics simulation completes at 2,569.

Against its nearest rivals, the Core Ultra 5 245 shows tight competition. The AMD Ryzen 7 PRO 5755G averages 49,196, which is 0.4% above the Core Ultra 5 245’s average of 48,995. The AMD Ryzen 9 7900 averages 49,228, a 0.5% lead. The Intel Xeon Gold 5318H averages 48,698, a 0.6% deficit. The Intel Core i5-14600K averages 48,618, a 0.8% deficit. These deltas indicate that the Core Ultra 5 245 sits within a single percentage point of four established CPUs, making its measured performance broadly competitive with a wide range of desktop and workstation parts.

The Arc G3 has no such comparisons available. Its nearest rivals list is empty, and its average benchmark score is zero. The only conclusion the data supports is that the Core Ultra 5 245 delivers measurable performance, while the Arc G3 does not yet have any recorded measurements.

The Core Ultra 5 245 has 3 MB of L2 cache per core and 24 MB of shared L3 cache. The desktop chip carries more cache at every level above L1.

Memory support diverges by platform. The Arc G3 uses LPDDR5X with a dual-channel bus and 136.5 GB/s bandwidth. The Core Ultra 5 245 uses DDR5 with a dual-channel bus and 102.4 GB/s bandwidth. The mobile chip offers higher memory bandwidth despite lower power, while the desktop chip offers ECC memory support, which the Arc G3 lacks.

PCIe connectivity also differs sharply. The Arc G3 provides Gen 5 with 4 CPU lanes, while the Core Ultra 5 245 provides Gen 5 with 20 CPU lanes. The desktop chip enables far more expansion for GPUs, storage, and peripherals. The integrated graphics differ as well: the Arc G3 pairs with Arc B370 graphics, while the Core Ultra 5 245 pairs with Arc Xe-LPG Graphics 64EU.

Physical and platform details reinforce the split. The Arc G3 uses an Intel BGA 2540 socket with a mobile market segment. The Core Ultra 5 245 uses an Intel Socket 1851 with a desktop market segment. The Core Ultra 5 245 lists 17,800 million transistors on a 243 mm² die, while the Arc G3 has no transistor or die size data. The Core Ultra 5 245 has a release date of January 2025, while the Arc G3 has a release date of May 2026. Neither processor has an unlocked multiplier.

The Core Ultra 5 245 has a part number of SRVFE, while the Arc G3 has a part number of SA4QZ. Both processors are listed as active in production. The Core Ultra 5 245 belongs to the Core Ultra Series 2 family, while the Arc G3 has no series designation. These architectural differences explain the performance gap: the desktop chip uses a faster clock, more cache, more PCIe lanes, and a desktop socket, while the mobile chip uses a lower clock, less cache, fewer PCIe lanes, and a BGA package optimized for portable systems.
