Intel Arc G3 EXTREME vs Intel Processor U300L Comparison

Head-to-Head Benchmarks

The Intel Arc G3 EXTREME and Intel Processor U300L occupy very different positions in the database, and the benchmark data confirms a wide performance gap between them. The Arc G3 EXTREME delivers an average benchmark score of 36,699, placing it at the 85th percentile of all CPUs tracked. The U300L, by contrast, sits at the 50th percentile with an average benchmark score of 0, indicating that no benchmark results have been recorded for it in the current database.

The Arc G3 EXTREME shows its strength in multi-threaded workloads. In Cinebench R23 multi-core, it scores 14,655 points, while its single-core result in the same test reaches 1,862. The Cinebench R20 run shows 10,945 multi-core and 1,545 single-core, and the older Cinebench R15 test produces 2,192 multi-core and 267 single-core. These numbers establish a processor that scales well across both lightly threaded and heavily threaded tasks.

PassMark results for the Arc G3 EXTREME reinforce this picture. The multithread score of 30,659 and single-thread score of 4,293 show balanced performance. Integer math reaches 71,164, floating point math hits 86,929, and extended instructions score 24,017. Data compression scores 307,094, while data encryption manages 23,881. Random string sorting completes at 37,331, and the physics test records 2,515. The find prime numbers test returns 248.

The U300L has no recorded benchmark scores in the database. This absence means direct numerical comparisons between the two processors cannot be made from measured results. What the data does show is the U300L's lower hardware ceiling: 5 cores and 6 threads, a base clock of 1.20 GHz, and a boost clock of 4.40 GHz. The Arc G3 EXTREME uses 14 cores and 14 threads, with a base clock of 1.90 GHz and a boost clock of 4.70 GHz. Every clock and core advantage sits with the Arc G3 EXTREME.

The nearest rivals to the Arc G3 EXTREME provide context for its standing. The Intel Core Ultra 5 225 averages 36,938, which is 0.6% higher. The AMD Ryzen 5 5600F averages 36,945, 0.7% higher. The AMD Ryzen 5 5500X3D averages 37,018, 0.9% higher. The AMD Ryzen AI 7 PRO 450 averages 37,093, 1.1% higher. These are all marginal deltas, meaning the Arc G3 EXTREME sits in a competitive cluster where no rival exceeds it by more than 1.1%. The U300L has no nearest rivals listed, which further separates it from the comparison field.

The Verdict

The recorded data points to a clear split in purpose. The Intel Arc G3 EXTREME is the stronger processor by every measurable specification in the database. Its 14 cores and 14 threads, higher clocks, larger cache hierarchy, and 85th percentile ranking place it in a performance class that the U300L does not approach. The Arc G3 EXTREME also posts a full set of benchmark results, while the U300L has none recorded.

The U300L is a lower-power part with a 15 W TDP, fewer cores, and slower clocks. Its 50th percentile ranking and absence of benchmark scores indicate that it is not designed for the same workload profile. The Arc G3 EXTREME consumes 25 W, which is higher but still within a mobile envelope.

Buyers who need the measured performance from Cinebench and PassMark results should select the Arc G3 EXTREME. The data shows it delivers multi-core and single-core scores that place it among CPUs with average benchmark scores around 36,699. The U300L, with no recorded benchmarks, cannot be positioned against those numbers. The choice, strictly from the data, depends on whether the workload requires the Arc G3 EXTREME's core count, cache size, and clock speeds, or whether the U300L's lower TDP and different socket fit a more constrained design.

Architecture Differences

The two processors come from different Intel design families. The Arc G3 EXTREME uses the Panther Lake codename and is built on a 3 nm process node, fabricated by Intel. The U300L uses the Raptor Lake architecture with the Raptor Lake-PS codename and is built on a 10 nm process node, also fabricated by Intel. The process node difference is substantial: 3 nm versus 10 nm means the Arc G3 EXTREME uses a significantly more advanced manufacturing technology.

The cache hierarchies differ as well. The Arc G3 EXTREME provides 192 KB of L1 per core, 2.5 MB of L2 per core, and 18 MB of shared L3. The U300L provides 80 KB of L1 per core, 1.25 MB of L2 per core, and 8 MB of shared L3. The Arc G3 EXTREME has more than double the L3 cache and larger per-core L1 and L2 allocations.

Memory support also separates the two. The Arc G3 EXTREME supports LPDDR5X memory over a dual-channel bus with a recorded bandwidth of 136.5 GB/s. The U300L supports DDR4 and DDR5 memory over a dual-channel bus, but the database records no bandwidth figure for it. Neither processor supports ECC memory.

The integrated graphics differ. The Arc G3 EXTREME pairs with an Arc B390 iGPU, while the U300L uses UHD Graphics 48EU. The PCIe implementation also differs: the Arc G3 EXTREME uses Gen 5 with 4 lanes (CPU only), while the U300L uses Gen 4 with 8 lanes (CPU only).

The sockets are incompatible. The Arc G3 EXTREME uses Intel BGA 2540, while the U300L uses Intel Socket 1700. The release dates differ as well: the Arc G3 EXTREME launched on May 27, 2026, and the U300L launched on April 7, 2024.

Specification Differences

The core and thread counts mark the largest specification gap. The Arc G3 EXTREME has 14 cores and 14 threads, while the U300L has 5 cores and 6 threads. The Arc G3 EXTREME has no hyper-threading, matching its core count to its thread count. The U300L has 6 threads from 5 cores, indicating one core supports an extra thread.

Clock speeds favor the Arc G3 EXTREME. Its base clock is 1.90 GHz and boost clock is 4.70 GHz. The U300L's base clock is 1.20 GHz and boost clock is 4.40 GHz. The Arc G3 EXTREME leads by 0.70 GHz at base and 0.30 GHz at boost.

Power draw differs. The Arc G3 EXTREME has a 25 W TDP, while the U300L has a 15 W TDP. Both are mobile market segments and both are currently in active production. Neither processor has an unlocked multiplier.

The Arc G3 EXTREME has a part number of SA4R3, and the U300L has part numbers SRPEKSRPEM. The U300L carries a launch MSRP of $107, while the Arc G3 EXTREME has no launch MSRP recorded.
