Intel Arc G3 EXTREME vs Intel Core 3 100UL Comparison

The Verdict

The database comparison shows a decisive performance gap between these two Intel processors. The Intel Arc G3 EXTREME, a Panther Lake part, records an average benchmark score of 36699 and sits in the 85th percentile of all CPUs. The Intel Core 3 100UL, a Raptor Lake-PS part, has no recorded benchmark scores and sits in the 50th percentile. The Arc G3 EXTREME is the clear choice for any workload where raw compute throughput matters. Its 14 cores and 14 threads, paired with a 4.70 GHz boost clock, deliver a level of performance that the Core 3 100UL cannot match on any metric present in the database. For systems requiring the highest multi-threaded and single-threaded performance in the mobile segment, the Arc G3 EXTREME is the only option supported by data. The Core 3 100UL, with no measured scores, offers no verifiable performance advantage in any category.

Architecture Differences

The two processors come from entirely different design generations. The Arc G3 EXTREME uses the Panther Lake codename and is fabricated on Intel's 3 nm process node. The Core 3 100UL uses the Raptor Lake-PS codename and is built on a 10 nm process node. This process gap alone explains a significant portion of the performance difference, as the newer node allows for higher transistor density and lower power consumption per unit of work.

Core configurations differ substantially. The Arc G3 EXTREME has 14 cores and 14 threads, meaning every core is a single thread. The Core 3 100UL has 6 cores and 8 threads, indicating a hybrid layout with some cores supporting two threads. The Arc G3 EXTREME operates at a base clock of 1.90 GHz and boosts to 4.70 GHz. The Core 3 100UL has a base clock of 1.20 GHz and a boost clock of 4.50 GHz. The Arc G3 EXTREME holds a 0.20 GHz advantage in boost frequency and a 0.70 GHz advantage in base frequency.

Cache hierarchies reflect the architectural chasm. The Arc G3 EXTREME offers 192 KB of L1 cache per core, 2.5 MB of L2 cache per core, and 18 MB of shared L3 cache. The Core 3 100UL offers 80 KB of L1 per core, 1.25 MB of L2 per core, and 10 MB of shared L3. This gives the Arc G3 EXTREME 2.4 times the L1 per core, twice the L2 per core, and 1.8 times the total L3 cache. For workloads that repeatedly access working sets, the larger caches reduce memory stalls.

Memory support diverges as well. The Arc G3 EXTREME supports LPDDR5X memory over a dual-channel bus with a recorded bandwidth of 136.5 GB/s. The Core 3 100UL supports both DDR4 and DDR5 memory over a dual-channel bus, but the database records no bandwidth figure. The Arc G3 EXTREME uses the Intel BGA 2540 socket, while the Core 3 100UL uses the Intel Socket 1700. PCIe connectivity differs: the Arc G3 EXTREME provides Gen 5 with 4 lanes for the CPU, while the Core 3 100UL provides Gen 4 with 8 lanes. Integrated graphics also change, with the Arc G3 EXTREME featuring an Arc B390 GPU and the Core 3 100UL featuring UHD Graphics 64EU. The Arc G3 EXTREME is classified as a mobile part, while the Core 3 100UL is classified as a desktop part. Neither processor supports ECC memory, and both are actively in production. The Arc G3 EXTREME was released on 2026-05-27, while the Core 3 100UL was released on 2024-04-07.

Where Each One Wins

The Arc G3 EXTREME wins in every measured category. The benchmark data records 17 distinct test scores for the Arc G3 EXTREME, and the Core 3 100UL has zero recorded scores. Consequently, the Arc G3 EXTREME records 17 wins and the Core 3 100UL records 0 wins in the head-to-head comparison.

The Arc G3 EXTREME demonstrates particular strength in multi-threaded rendering workloads. In Cinebench R23 multi-core, it scores 14655, and in Cinebench R20 multi-core, it scores 10945. These figures indicate heavy parallel throughput that the 6-core, 8-thread Core 3 100UL cannot approach given its lower core count and smaller cache. The Arc G3 EXTREME also excels in PassMark integer math, scoring 71164, and floating-point math, scoring 86929. These scores point to general-purpose compute capability suitable for scientific calculations, financial modeling, and physics simulations.

Single-threaded performance favors the Arc G3 EXTREME as well. It scores 4293 in PassMark single-thread and 1862 in Cinebench R23 single-core. The higher boost clock of 4.70 GHz supports these results. The Core 3 100UL has no recorded single-thread scores, so any claim of competitiveness in this area lacks data support.

For the Core 3 100UL, the only recorded advantage is its lower TDP of 15 watts versus the Arc G3 EXTREME's 25 watts. This makes the Core 3 100UL a candidate for power-constrained desktop environments where the 10-watt difference matters and performance requirements are minimal. The Core 3 100UL also supports DDR4 memory, which may be relevant for systems reusing older memory modules, but the database records no bandwidth figures to quantify any impact. The Core 3 100UL's Gen 4 PCIe with 8 lanes provides more direct CPU-attached lanes than the Arc G3 EXTREME's Gen 5 with 4 lanes, which could matter for setups with multiple Gen 4 devices.

Head-to-Head Benchmarks

The head-to-head benchmark table is empty, because the Core 3 100UL has no recorded scores. The Arc G3 EXTREME, however, has 17 measured scores that define its performance envelope. The most informative comparisons come from placing these scores against the nearest rivals in the database.

The Arc G3 EXTREME's average benchmark score of 36699 places it within 0.6% of the Intel Core Ultra 5 225, which averages 36938. It trails the AMD Ryzen 5 5600F by 0.7%, that chip averaging 36945. The AMD Ryzen 5 5500X3D leads the Arc G3 EXTREME by 0.9%, with an average of 37018. The AMD Ryzen AI 7 PRO 450 is 1.1% ahead, averaging 37093. These deltas are all below 1.5%, indicating that the Arc G3 EXTREME sits in a tightly contested performance band around the 37000 average score mark.

In Cinebench R23 multi-core, the Arc G3 EXTREME scores 14655. This workload stresses all 14 cores simultaneously and benefits from the 18 MB L3 cache. The Cinebench R20 multi-core score of 10945 reinforces the multi-threaded strength. The Cinebench R15 multi-core score of 2192 shows a similar pattern at the older test's lighter load.

Single-threaded performance is equally solid. The Cinebench R23 single-core score of 1862 and the Cinebench R20 single-core score of 1545 both reflect the 4.70 GHz boost clock. The PassMark single-thread score of 4293 confirms this. The Cinebench R15 single-core score of 267 is the lowest recorded single-thread figure, likely due to the test's age and shorter duration.

PassMark tests reveal workload-specific behavior. The data compression score of 307094 is the highest single test result for the Arc G3 EXTREME, showing strong throughput in compression algorithms. Data encryption scores 23881, and extended instructions score 24017. The find prime numbers test scores only 248, which is a low figure that indicates weak performance in this specific integer-heavy, single-threaded workload. Floating-point math scores 86929, while integer math scores 71164, showing a 22% advantage for floating-point operations. The multithread score of 30659 and the physics score of 2515 round out the PassMark suite. Random string sorting scores 37331, which reflects memory access patterns and cache behavior.

The percentile placement of 85 means the Arc G3 EXTREME outperforms 85% of all CPUs in the database. The Core 3 100UL sits at the 50th percentile, but with no scores, this figure represents its default classification rather than measured performance. The database shows no wins for the Core 3 100UL in any head-to-head test. Every recorded benchmark belongs to the Arc G3 EXTREME, and the data consistently indicates that the Arc G3 EXTREME is the superior processor for all measured workloads.
