Intel Arc G3 EXTREME vs Intel Processor 300T Comparison

Where Each One Wins

The Intel Arc G3 EXTREME is a mobile processor built around the Panther Lake architecture, and the recorded benchmark data shows it holds a decisive advantage in every measurable workload. The Intel Processor 300T, by contrast, has no benchmark entries in the database, so the comparison is one-sided in terms of recorded performance. The Arc G3 EXTREME sits at the 85th percentile among all CPUs, while the Processor 300T sits at the 50th percentile. That gap alone positions the two parts in different performance classes.

The Arc G3 EXTREME is designed for sustained multithreaded throughput. Its Cinebench R23 multicore score of 14655 points places it far ahead of what a dual-core desktop part could deliver. The single-core results are similarly strong, with a Cinebench R23 single-core score of 1862 points. The Processor 300T has no recorded Cinebench scores, no PassMark scores, and no average benchmark score in the database, meaning the data cannot show any workload where it wins. The Arc G3 EXTREME also records an average benchmark score of 36699, while the Processor 300T records 0. The use-case split is therefore clear: the Arc G3 EXTREME wins every category where data exists, including multithreaded rendering, single-thread responsiveness, encryption, compression, and math workloads.

The Processor 300T still has a role in the database as a low-power desktop part with a 35 W TDP and a 3.40 GHz base clock, but its benchmark profile is empty. The Arc G3 EXTREME uses a 25 W TDP, which is lower than the Processor 300T's 35 W TDP, and it still delivers the recorded performance above. The data suggests the Arc G3 EXTREME is the stronger part for any compute-heavy task, while the Processor 300T is simply a baseline desktop processor without recorded performance metrics.

Architecture Differences

The two processors come from different Intel families and target different market segments. The Arc G3 EXTREME uses the Panther Lake architecture, fabricated on a 3 nm process node at Intel. The Processor 300T uses the Raptor Lake architecture, specifically Raptor Lake-S, fabricated on a 10 nm process node. Both are built by Intel, but the process gap is substantial: 3 nm versus 10 nm.

Core counts differ sharply. The Arc G3 EXTREME has 14 cores and 14 threads, meaning it has no hyperthreading. The Processor 300T has 2 cores and 4 threads, which means it does use hyperthreading. The Arc G3 EXTREME has a base clock of 1.90 GHz and a boost clock of 4.70 GHz. The Processor 300T has a base clock of 3.40 GHz and no recorded boost clock. Despite the lower base clock, the Arc G3 EXTREME's higher core count and boost capability explain its benchmark dominance.

Cache hierarchies are also different. The Arc G3 EXTREME has 192 KB of L1 cache per core, 2.5 MB of L2 cache per core, and 18 MB of shared L3 cache. The Processor 300T has 80 KB of L1 cache per core, 1.25 MB of L2 cache per core, and 6 MB of shared L3 cache. The Arc G3 EXTREME's L3 cache is three times larger, and its per-core L2 cache is double. The Processor 300T has a recorded die size of 163 mm², while the Arc G3 EXTREME has no die size recorded.

Memory support differs as well. The Arc G3 EXTREME supports LPDDR5X memory over a dual-channel bus with a recorded memory bandwidth of 136.5 GB/s. The Processor 300T supports both DDR4 and DDR5 memory over a dual-channel bus, but no bandwidth figure is recorded. The Arc G3 EXTREME uses an Intel BGA 2540 socket, while the Processor 300T uses Intel Socket 1700. The Arc G3 EXTREME provides PCIe Gen 5 with 4 lanes (CPU only), whereas the Processor 300T provides PCIe Gen 5 with 16 lanes (CPU only). The Arc G3 EXTREME integrates Arc B390 graphics, while the Processor 300T integrates UHD Graphics 710.

The release dates are recorded in the database: the Arc G3 EXTREME was released on 2026-05-27, and the Processor 300T was released on 2024-01-07. The Arc G3 EXTREME has a part number of SA4R3, while the Processor 300T has a part number of SRN3K. Neither processor has an unlocked multiplier. The Arc G3 EXTREME is classified as a mobile part, and the Processor 300T is classified as a desktop part. The Arc G3 EXTREME has a launch MSRP of none recorded, while the Processor 300T has a launch MSRP of $82.

Head-to-Head Benchmarks

The head-to-head benchmark table in the database is empty, so no direct paired scores exist between the two processors. The available comparison must instead use the Arc G3 EXTREME's recorded benchmark suite and the Processor 300T's absence of recorded scores.

The Arc G3 EXTREME records a Cinebench R23 multicore score of 14655 and a single-core score of 1862. In Cinebench R20, it records 10945 multicore and 1545 single-core. In Cinebench R15, it records 2192 multicore and 267 single-core. The Processor 300T has no Cinebench entries, so every rendering workload in the database goes to the Arc G3 EXTREME.

PassMark results reinforce the same pattern. The Arc G3 EXTREME records a multithread score of 30659 and a single-thread score of 4293. Its integer math score is 71164, floating point math is 86929, and extended instructions are 24017. Data compression scores 307094, data encryption scores 23881, and find prime numbers scores 248. Random string sorting scores 37331, and physics scores 2515. The Processor 300T has no PassMark results recorded at all.

The Arc G3 EXTREME's nearest rivals in the database are the Intel Core Ultra 5 225, the AMD Ryzen 5 5600F, the AMD Ryzen 5 5500X3D, and the AMD Ryzen AI 7 PRO 450. The Arc G3 EXTREME trails the Core Ultra 5 225 by 0.6%, trails the Ryzen 5 5600F by 0.7%, trails the Ryzen 5 5500X3D by 0.9%, and trails the Ryzen AI 7 PRO 450 by 1.1%. Those delta percentages are small, meaning the Arc G3 EXTREME performs within roughly one percent of all four rivals despite having a lower average benchmark score than each of them. The Arc G3 EXTREME's average benchmark score of 36699 sits just below the 36938 of the Core Ultra 5 225 and the 36945 of the Ryzen 5 5600F.

The Processor 300T has no nearest rivals recorded and no average benchmark score, so it cannot be positioned against any other processor in the database. Its percentile rank of 50 places it at the midpoint of all CPUs, while the Arc G3 EXTREME's rank of 85 places it well above the midpoint. The recorded data shows the Arc G3 EXTREME as the only one of the two with measurable performance, and its scores place it in the upper tier of the database. The Processor 300T remains a specification-only entry with no performance data to compare.
