Intel Arc G3 vs Intel Processor 300 Comparison

The Verdict

The Intel Arc G3 and Intel Processor 300 occupy entirely different segments of the processor market, and the recorded data shows no overlap in their intended use cases. The Arc G3 is a 14-core, 14-thread mobile part built on Intel's 3 nm process, designed for thin-and-light laptops with a 25 W TDP. The Intel Processor 300 is a 2-core, 4-thread desktop chip on the older 10 nm node with a 46 W TDP, aimed at basic desktop workloads. The data indicates that the Arc G3 delivers 12 more cores and 10 more threads than the Processor 300, which translates into substantially higher multi-threaded throughput for parallel workloads. The Processor 300 counters with a higher base clock of 3.90 GHz versus 1.90 GHz, but it lacks a boost clock entirely, meaning it cannot dynamically increase frequency under load. The Arc G3 reaches 4.60 GHz at boost, so in single-threaded bursts, the mobile part can actually surpass the desktop chip's fixed clock speed. Benchmarks for both parts are absent from the database, so direct score comparisons cannot be made, but the architectural specifications alone separate these processors into distinct buying categories: the Arc G3 for portable, power-efficient computing, and the Processor 300 for stationary, low-cost desktop builds.

Where Each One Wins

The Arc G3 wins in any scenario that benefits from core count and thread parallelism. With 14 cores and 14 threads, it has a 7x core advantage and a 3.5x thread advantage over the Processor 300. This makes the Arc G3 the clear choice for multi-threaded productivity tasks, content creation, and modern workloads that scale across cores. Its 18 MB of shared L3 cache dwarfs the Processor 300's 6 MB, providing a larger working set for data-heavy applications. The Arc G3 also integrates the Arc B370 graphics, which represents a significantly more capable integrated GPU solution compared to the UHD Graphics 710 found in the Processor 300. For mobile users, the 25 W TDP versus 46 W means the Arc G3 consumes less power, making it suitable for battery-powered devices. The Processor 300 wins in raw single-threaded baseline performance, as its 3.90 GHz base clock is more than double the Arc G3's 1.90 GHz base, and it does not require a boost state to reach that speed. It also offers 16 PCIe Gen 5 lanes versus only 4 on the Arc G3, providing far more expansion bandwidth for desktop peripherals, GPUs, and NVMe storage. The Processor 300 uses DDR4 and DDR5 memory, giving builders flexibility in platform choice, while the Arc G3 is limited to LPDDR5X. For users who need a simple, always-on desktop processor with fast base clock responsiveness, the Processor 300 holds the advantage.

Architecture Differences

The two processors come from different Intel design generations and process nodes. The Arc G3 uses the Panther Lake architecture on a 3 nm process, while the Processor 300 uses Raptor Lake-S architecture on a 10 nm process. This node difference is substantial, as the 3 nm process allows for significantly denser transistor packing and lower power consumption per unit of performance. The Arc G3's die is not recorded in the database, but the Processor 300's die size is 163 mm². The core configurations diverge sharply: the Arc G3 features 14 cores and 14 threads with no hyper-threading, while the Processor 300 features 2 cores and 4 threads, indicating hyper-threading support. Cache hierarchies differ in both capacity and allocation. The Arc G3 has 192 KB of L1 cache per core, 2.5 MB of L2 per core, and 18 MB of shared L3. The Processor 300 has 80 KB of L1 per core, 1.25 MB of L2 per core, and 6 MB of shared L3. The Arc G3's per-core L2 is exactly double that of the Processor 300, and its L3 is three times larger. Memory support diverges as well: the Arc G3 uses LPDDR5X in a dual-channel configuration with a measured memory bandwidth of 136.5 GB/s, while the Processor 300 supports DDR4 and DDR5 but has no recorded bandwidth figure. The Arc G3 uses the Intel BGA 2540 socket, indicating a soldered mobile design, whereas the Processor 300 uses Intel Socket 1700, a standard desktop socket that allows user replacement and upgrades. PCIe connectivity differs dramatically: the Arc G3 provides Gen 5 with only 4 lanes, while the Processor 300 provides Gen 5 with 16 lanes. Neither processor supports ECC memory, and neither has an unlocked multiplier. The integrated graphics also represent different tiers: the Arc G3 pairs with Arc B370 graphics, while the Processor 300 uses UHD Graphics 710. The release dates are recorded as January 7, 2024 for the Processor 300 and May 27, 2026 for the Arc G3, placing the mobile part over two years newer.

FAQ

Head-to-Head Benchmarks

The database contains no recorded benchmark scores for either the Intel Arc G3 or the Intel Processor 300, and neither part has nearest rival entries or head-to-head benchmark results. This means direct performance deltas cannot be quantified from measured test data. However, the architectural specifications provide a basis for comparative analysis. The most significant advantage for the Arc G3 lies in core count: 14 cores versus 2 cores, a 7-fold increase. Even accounting for the fact that the Processor 300 supports hyper-threading with 4 threads versus the Arc G3's 14 threads, the Arc G3 still offers a 3.5x thread advantage. In multi-threaded workloads that scale linearly, the Arc G3 should deliver substantially higher throughput, though the exact percentage cannot be stated without benchmark data. The Arc G3's L3 cache of 18 MB versus 6 MB represents a 200% larger shared cache, which benefits workloads with large working sets. Its memory bandwidth of 136.5 GB/s, while only recorded for the Arc G3, indicates a high-bandwidth LPDDR5X implementation suited for integrated graphics performance. The Arc G3's integrated Arc B370 GPU is a discrete-class graphics solution, while the Processor 300's UHD Graphics 710 is an entry-level configuration. In gaming and GPU-accelerated tasks, the Arc G3's graphics solution should be decisively faster, though no frame rate data exists in the database. The Processor 300's advantages are in base clock and PCIe expandability. Its 3.90 GHz base clock is 2.00 GHz higher than the Arc G3's 1.90 GHz base, which gives it an edge in latency-sensitive, single-threaded tasks that do not boost. However, the Arc G3's 4.60 GHz boost clock exceeds the Processor 300's fixed 3.90 GHz by 0.70 GHz, so in burst workloads, the mobile chip can pull ahead. The Processor 300's 16 PCIe Gen 5 lanes versus 4 on the Arc G3 make it the only option for discrete GPU setups requiring full-bandwidth connectivity. Both processors share the same percentile rank of 50 against all CPUs in the database, but this percentile is based on an average benchmark score of 0 for both, which reflects missing benchmark data rather than equal performance. The Intel Processor 300 has a recorded launch MSRP of $82, while the Arc G3 has no launch MSRP recorded, confirming their different market positions: one as an entry-level desktop part, the other as a mobile processor with no standalone retail pricing structure. The power envelope further distinguishes them, with the Arc G3 rated at 25 W TDP and the Processor 300 at 46 W, a 21 W difference that makes the Arc G3 far more suitable for fanless or low-power mobile designs. Socket compatibility is another divider: the Arc G3 uses Intel BGA 2540, a soldered connection, while the Processor 300 uses Intel Socket 1700, allowing installation in desktop motherboards. The die size of the Processor 300 is recorded as 163 mm², but no die size exists for the Arc G3, so silicon area comparison cannot be made. The release date gap of over two years, from January 2024 to May 2026, places the Arc G3 in a newer generation with the 3 nm process, while the Processor 300 remains on 10 nm. Given the absence of benchmark scores, the data indicates that the Arc G3 is the superior multi-threaded and mobile solution, while the Processor 300 is the superior desktop expansion platform with a higher fixed base clock.
