Architecture Differences

The Intel Arc G3 and the Intel Core Ultra 5 225 represent two distinct design philosophies from Intel, differentiated by their target platforms and architectural implementations. The Arc G3 is a mobile processor built on the Panther Lake architecture, featuring 14 cores and 14 threads. The Core Ultra 5 225 is a desktop part based on the Arrow Lake architecture, with 10 cores and 10 threads. Both use a 3 nm manufacturing process, but the foundries differ: Intel fabricates the Arc G3, while TSMC produces the Core Ultra 5 225.

Cache hierarchies show notable divergence. The Intel Arc G3 has 192 KB of L1 cache per core and 2.5 MB of L2 cache per core, with a shared 18 MB L3 cache. The Intel Core Ultra 5 225 also uses 192 KB of L1 cache per core but increases L2 to 3 MB per core and L3 to a shared 20 MB. This gives the desktop chip a larger total cache footprint, which can favor workloads that benefit from higher-capacity on-die storage.

Memory support differs significantly. The Arc G3 uses LPDDR5X memory with a bandwidth of 136.5 GB/s, designed for power-efficient mobile operation. The Core Ultra 5 225 uses DDR5 memory with a bandwidth of 102.4 GB/s. Despite the lower bandwidth figure, the desktop platform typically allows for higher-capacity memory configurations, though the raw bandwidth advantage belongs to the mobile chip.

PCIe connectivity also separates the two. The Arc G3 provides Gen 5 with 4 lanes (CPU only), while the Core Ultra 5 225 provides Gen 5 with 20 lanes (CPU only). This is a substantial difference for desktop users who need to connect multiple high-speed peripherals, GPUs, or NVMe storage devices. The mobile chip's lane count is necessarily limited by its form factor and power envelope.

Integrated graphics differ as well. The Arc G3 includes an Arc B370 iGPU, while the Core Ultra 5 225 includes an Arc Xe-LPG Graphics 16EU solution. The B370 in the mobile part is a higher-tier integrated graphics solution compared to the 16EU configuration in the desktop chip, which is relevant for mobile users who rely on iGPU performance for media and light gaming.

Thermal design power and market positioning further separate the two. The Arc G3 is rated at 25 W TDP, and the Core Ultra 5 225 is rated at 65 W TDP. The mobile chip's lower power draw aligns with its portable segment, while the desktop chip's higher TDP allows for sustained performance in desktop chassis. The Core Ultra 5 225 has a launch MSRP of $246, while the Arc G3 has no recorded launch MSRP.

The Verdict

The recorded data positions the Intel Core Ultra 5 225 as the stronger processor for desktop workloads. It holds the 85th percentile among all CPUs, with an average benchmark score of 36,938. The Intel Arc G3 sits at the 50th percentile with no benchmark scores recorded, making direct performance comparison impossible from the database. The Core Ultra 5 225 delivers a single-thread score of 4,412 in PassMark, a multi-thread score of 30,459, and a Cinebench R23 multi-core score of 25,891. These figures indicate a capable desktop processor that competes closely with AMD Ryzen 5 5600F, AMD Ryzen 5 5500X3D, AMD Ryzen AI 7 PRO 450, and Intel Core i9-12900T, all within 0.5% of its average score.

For mobile users, the Intel Arc G3 offers 14 cores, a higher memory bandwidth of 136.5 GB/s, and a lower 25 W TDP, making it suited for portable devices where power efficiency and integrated graphics matter. Its Arc B370 iGPU is a stronger integrated solution than the Core Ultra 5 225's Arc Xe-LPG Graphics 16EU, which could benefit light gaming or media workloads on the go. However, without benchmark scores in the database, the Arc G3's actual performance level remains unquantified relative to the Core Ultra 5 225.

The data suggests that the Core Ultra 5 225 is the choice for desktop builders who need verified multi-threaded and single-threaded performance, higher PCIe lane availability (20 lanes vs. 4 lanes), and a larger L3 cache (20 MB vs. 18 MB). The Arc G3 is the option for mobile platforms where the 25 W TDP, LPDDR5X support, and integrated Arc B370 graphics align with portable use cases. The higher base clock (3.30 GHz vs. 1.90 GHz) and boost clock (4.90 GHz vs. 4.60 GHz) on the Core Ultra 5 225 further reinforce its desktop performance advantage, though the Arc G3's 14-core configuration suggests potential for multi-threaded mobile workloads if software scales accordingly.

Specification Differences

The two processors differ across nearly every core specification. The Intel Arc G3 has 14 cores and 14 threads, while the Intel Core Ultra 5 225 has 10 cores and 10 threads. Base clocks are 1.90 GHz for the Arc G3 and 3.30 GHz for the Core Ultra 5 225. Boost clocks are 4.60 GHz and 4.90 GHz, respectively.

Cache configurations differ in L2 and L3 capacity. The Arc G3 provides 2.5 MB of L2 per core and 18 MB of shared L3. The Core Ultra 5 225 provides 3 MB of L2 per core and 20 MB of shared L3. L1 cache is identical at 192 KB per core.

Memory support diverges: the Arc G3 uses LPDDR5X with 136.5 GB/s bandwidth, and the Core Ultra 5 225 uses DDR5 with 102.4 GB/s bandwidth. Both use dual-channel memory buses, and neither supports ECC memory.

PCIe capabilities differ sharply. The Arc G3 offers Gen 5 with 4 lanes (CPU only), while the Core Ultra 5 225 offers Gen 5 with 20 lanes (CPU only). This is the largest interface gap between the two.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark comparisons between the Intel Arc G3 and the Intel Core Ultra 5 225. The head-to-head benchmark table is empty, and the win counts are zero for both processors. This means the only quantitative performance data comes from the Core Ultra 5 225's recorded benchmarks and its nearest rival comparisons.

The Intel Core Ultra 5 225 delivers a Cinebench R23 multi-core score of 25,891 and a single-core score of 3,655. In Cinebench R20, it scores 6,317 multi-core and 891 single-core. Cinebench R15 results show 2,609 multi-core and 368 single-core. These scores indicate strong scaling across different Cinebench versions, with multi-core performance consistently dominating single-core results.

In PassMark tests, the Core Ultra 5 225 shows varied strengths. It scores 302,811 in data compression, 22,285 in data encryption, and 27,162 in extended instructions. Floating point math reaches 92,038, and integer math hits 65,345. The multi-thread score is 30,459, and the single-thread score is 4,412. Physics testing yields 2,342, and random string sorting produces 36,590. Prime number finding scores 358.

The nearest rivals for the Core Ultra 5 225 are tightly clustered. AMD Ryzen 5 5600F has an average score of 36,945 with a 0% delta. AMD Ryzen 5 5500X3D scores 37,018, which is 0.2% lower. AMD Ryzen AI 7 PRO 450 scores 37,093, 0.4% lower. Intel Core i9-12900T scores 37,112, 0.5% lower. This places the Core Ultra 5 225 at the bottom of this small group, but the differences are negligible, within half a percentage point across all rivals.

The Arc G3 has no benchmark scores, no average benchmark score, and no nearest rivals in the database. Its percentile rank of 50 indicates it sits at the median of all CPUs, but this is not backed by any measured performance data. The lack of recorded benchmarks means the Arc G3's relative performance cannot be quantified against the Core Ultra 5 225 or any other processor in the database.

Given the data, the Core Ultra 5 225's performance profile is well established. Its average benchmark score of 36,938 is nearly identical to its closest rival, the AMD Ryzen 5 5600F, which scores 36,945. The Core Ultra 5 225 trails the Intel Core i9-12900T by only 0.5%, a margin that would be imperceptible in most real-world workloads. The Arc G3, by contrast, offers no measured data to compare, leaving its performance as an open question for mobile users until benchmark results are added to the database.
