AMD Ryzen 3 8300G vs Intel Arc G3 Comparison

Head-to-Head Benchmarks

The benchmark database currently contains no shared head-to-head benchmark entries for the AMD Ryzen 3 8300G and the Intel Arc G3. The recorded data shows the Ryzen 3 8300G has 17 completed benchmark scores across Cinebench R15, R20, R23, and Passmark workloads, while the Arc G3 has no recorded benchmark scores in the database at this time. This absence of overlapping measurements means a direct score-for-score comparison cannot be constructed from the available data.

The Ryzen 3 8300G's strongest recorded results come from Cinebench R23, where it posts a multicore score of 12217 and a singlecore score of 1724. In Cinebench R20, the multicore result is 5131 with a singlecore score of 724. The Cinebench R15 run shows a multicore score of 1231 and a singlecore score of 173. Passmark workloads show a multithread score of 14018, a single thread score of 3778, integer math at 40534, floating point math at 25336, extended instructions at 12354, data compression at 158952, data encryption at 9115, find prime numbers at 47, random string sorting at 19013, and physics at 755.

The Arc G3 has zero recorded benchmarks, so its performance profile is entirely unmeasured in the current database. The only quantitative performance indicator available for the Arc G3 is its percentile rank of 50 among all CPUs, which places it at the median of the distribution. The Ryzen 3 8300G, by contrast, holds a percentile rank of 72, meaning it sits above roughly 72 percent of all CPUs in the database. The average benchmark score for the Ryzen 3 8300G is 18169, while the Arc G3's average is 0 due to the lack of measurements.

Comparing the Ryzen 3 8300G to its nearest recorded rivals provides additional context. The AMD Ryzen 7 5700U posts an average score of 18176, a delta of 0 percent versus the Ryzen 3 8300G. The Intel Core i7-1365U averages 18177, also a 0 percent delta. The Intel Core i7-9700 averages 18180, a delta of -0.1 percent, meaning the Ryzen 3 8300G is essentially tied with all three. The Intel Core i5-1334U averages 18154, a delta of 0.1 percent, again a near-identical result. These figures indicate the Ryzen 3 8300G sits in a tightly packed performance band with these four rivals, none of which differ by more than 0.1 percent in average score.

Since the Arc G3 lacks both benchmark scores and nearest rival data, no delta comparisons can be made for it. The database therefore supports only a one-sided quantitative analysis for this pairing.

Architecture Differences

The two processors come from different manufacturing and design lineages. The AMD Ryzen 3 8300G uses the Zen 4 architecture with the Phoenix2 codename, built on a 4 nm process at TSMC. The Intel Arc G3 uses the Panther Lake codename with a 3 nm process at Intel's own foundry. The Ryzen 3 8300G is a desktop part on AMD Socket AM5, while the Arc G3 is a mobile part on Intel BGA 2540.

Core counts differ substantially. The Ryzen 3 8300G has 4 cores and 8 threads, indicating simultaneous multithreading. The Arc G3 has 14 cores and 14 threads, meaning it does not support hyperthreading and each core maps to a single thread. The Arc G3 therefore has more physical cores but the same number of threads per core ratio.

Clock speeds show the Ryzen 3 8300G with a base clock of 3.40 GHz and a boost clock of 4.90 GHz. The Arc G3 runs at a base clock of 1.90 GHz and a boost clock of 4.60 GHz. The Ryzen 3 8300G has a higher ceiling in both measurements.

Cache hierarchies differ significantly. The Ryzen 3 8300G has 64 KB of L1 cache per core, 1 MB of L2 cache per core, and 8 MB of shared L3 cache. The Arc G3 has 192 KB of L1 cache per core, 2.5 MB of L2 cache per core, and 18 MB of shared L3 cache. In per-core L1 and L2 terms, the Arc G3 has larger allocations, and its total L3 is more than double the Ryzen 3 8300G's.

Memory support also differs. The Ryzen 3 8300G uses DDR5 with dual-channel memory and a recorded memory bandwidth of 83.2 GB/s. The Arc G3 uses LPDDR5X, also dual-channel, with a memory bandwidth of 136.5 GB/s. The Arc G3's memory bandwidth is roughly 64 percent higher than the Ryzen 3 8300G's. The Ryzen 3 8300G supports ECC memory, while the Arc G3 does not.

PCIe connectivity differs as well. The Ryzen 3 8300G provides Gen 4 with 14 lanes from the CPU. The Arc G3 provides Gen 5 with 4 lanes from the CPU. The Ryzen 3 8300G offers more lanes but an older generation; the Arc G3 offers fewer lanes at a newer generation.

Integrated graphics also differ. The Ryzen 3 8300G includes Radeon 740M graphics. The Arc G3 includes Arc B370 graphics. The transistor count and die size are recorded only for the Ryzen 3 8300G at 20,900 million transistors and 137 mm². The Arc G3 has no transistor or die size data in the database.

Power consumption differs notably. The Ryzen 3 8300G has a TDP of 65 watts, while the Arc G3 has a TDP of 25 watts. The Arc G3 draws substantially less power on paper, which aligns with its mobile market segment.

The Verdict

The recorded data presents an incomplete picture for direct comparison. The AMD Ryzen 3 8300G has a full set of 17 benchmark scores, an average score of 18169, and a percentile rank of 72. The Intel Arc G3 has no benchmark scores, an average score of 0, and a percentile rank of 50. Any verdict must therefore rely on the specification differences and the limited performance data available.

The Ryzen 3 8300G demonstrates measurable performance in the database. Its nearest rivals, all within 0.1 percent average score, confirm it sits in a competitive mid-range band. The Arc G3 cannot be placed on the same performance scale because no measurements exist.

For users who require confirmed benchmark results, the Ryzen 3 8300G is the only option with recorded performance data. Its 4.90 GHz boost clock and 8 threads provide a known quantity for single-thread and multithread workloads. The Arc G3 offers a higher core count (14 versus 4), more L3 cache (18 MB versus 8 MB), and higher memory bandwidth (136.5 GB/s versus 83.2 GB/s), but these specifications are not backed by any benchmark scores in the database.

The Arc G3's lower TDP of 25 watts versus 65 watts suggests a different power envelope, but without performance data, the efficiency trade-off cannot be quantified. The Ryzen 3 8300G's launch MSRP of $176 is recorded, while the Arc G3 has no launch price.

Where Each One Wins

AMD Ryzen 3 8300G wins in every measured benchmark category because it has all the recorded scores. The data shows it completes Cinebench R23 multicore at 12217 and singlecore at 1724. Its Passmark single thread score of 3778 and multithread score of 14018 provide concrete reference points. Its percentile rank of 72 versus the Arc G3's 50 indicates it sits higher in the overall CPU distribution. It also supports ECC memory, uses the AM5 socket with 14 PCIe Gen 4 lanes, and has a recorded launch MSRP of $176.

Intel Arc G3 wins on specification grounds in several areas. It has more cores (14 versus 4), more L3 cache (18 MB versus 8 MB), higher per-core L1 and L2 cache allocations (192 KB and 2.5 MB versus 64 KB and 1 MB), higher memory bandwidth (136.5 GB/s versus 83.2 GB/s), a smaller process node (3 nm versus 4 nm), and a lower TDP (25 watts versus 65 watts). It also uses PCIe Gen 5 (4 lanes) versus the Ryzen 3 8300G's PCIe Gen 4 (14 lanes), and it has a newer release date of 2026-05-27 versus 2024-01-07.

For workloads where the database has measurements, the Ryzen 3 8300G is the only processor with demonstrated performance. For workloads that depend on raw core count, cache size, or memory bandwidth, the Arc G3's specifications suggest potential advantages, but the absence of benchmark scores leaves those advantages unverified in the current data.
