AMD Ryzen 3 8300G vs Intel Arc G3 EXTREME Comparison

Where Each One Wins

The benchmark data presents an unusually one-sided comparison. The Intel Arc G3 EXTREME wins every single recorded benchmark against the AMD Ryzen 3 8300G, taking all 17 head-to-head tests. The AMD processor does not secure a single victory in any measured workload, whether single-threaded, multi-threaded, or specialized instruction tasks.

The Intel part's advantages are largest in heavily parallel workloads. PassMark physics shows a 70% lead, floating point math sits 70.9% ahead, and multithread performance is 54.3% higher. These are workloads that scale with core count and memory bandwidth, and the Intel processor has clear structural advantages in both areas.

The AMD Ryzen 3 8300G still holds relevance in specific contexts. Its 72nd percentile ranking among all CPUs places it in the upper tier of desktop processors, and it delivers competitive single-thread scores for a 4-core part. The Radeon 740M integrated graphics and AM5 socket support give it a distinct desktop-oriented feature set that the Intel mobile chip cannot match, though those features do not appear in these specific CPU benchmark results.

Architecture Differences

The two processors come from fundamentally different design philosophies. The AMD Ryzen 3 8300G uses the Zen 4 architecture on TSMC's 4 nm process, built on the Phoenix2 die with 20,900 million transistors across a 137 mm² die. It is a desktop part on AMD Socket AM5 with 4 cores and 8 threads, reflecting a mainstream entry-point design.

The Intel Arc G3 EXTREME uses the Panther Lake codename on Intel's own 3 nm process node. It is a mobile processor on Intel BGA 2540 with 14 cores and 14 threads, meaning it has no hyperthreading or equivalent technology. The core count difference is substantial: 14 physical cores versus 4 physical cores with simultaneous multithreading.

Cache configurations differ sharply. The AMD chip provides 64 KB of L1 per core, 1 MB of L2 per core, and 8 MB of shared L3. The Intel part offers 192 KB of L1 per core, 2.5 MB of L2 per core, and 18 MB of shared L3. The larger per-core caches and more than double the L3 capacity give the Intel processor a meaningful advantage in cache-sensitive workloads.

Memory support also diverges. The AMD part uses DDR5 with dual-channel support and 83.2 GB/s of bandwidth, plus ECC memory support. The Intel chip uses LPDDR5X, also dual-channel, but with 136.5 GB/s of bandwidth and no ECC support. The 53.3 GB/s bandwidth advantage for Intel directly feeds its performance in memory-heavy tasks like data compression and encryption.

PCIe connectivity differs by generation and lane count. The AMD processor provides Gen 4 with 14 lanes from the CPU, while the Intel chip offers Gen 5 with 4 lanes. The AMD part has more physical lanes for desktop expansion, while the Intel part uses a newer generation with fewer lanes, consistent with its mobile positioning.

The integrated graphics also differ. AMD pairs the CPU with Radeon 740M graphics, while Intel includes Arc B390 graphics. The Intel Arc G3 EXTREME carries a 25 W TDP compared to the AMD part's 65 W, a notable efficiency gap given the Intel chip's far higher benchmark scores.

Release timing separates the two significantly. The AMD Ryzen 3 8300G launched in January 2024 with a launch MSRP of $176. The Intel Arc G3 EXTREME has a release date in May 2026 and no launch MSRP recorded in the database. The Intel chip also carries a newer generation label (Arc G3 Panther Lake) versus the Ryzen 3 Zen 4 Phoenix generation.

Head-to-Head Benchmarks

The Cinebench results show where the Intel processor builds its lead. In Cinebench R15 multicore, the Intel chip scores 2192 against 1231 for AMD, a 43.8% margin. The R15 single-core test shows 267 versus 173, a 35.2% lead. These early gaps grow in R20: multicore shows 10945 versus 5131, a 53.1% difference, and single-core shows 1545 versus 724, also 53.1%. The R23 results narrow somewhat, with multicore at 14655 versus 12217, a 16.6% gap, and single-core at 1862 versus 1724, a 7.4% difference. The R23 multicore margin is the smallest of any multi-threaded test, suggesting the AMD part scales relatively better as the workload duration increases, though it still loses.

PassMark results amplify the Intel advantage. Data compression shows 307094 versus 158952, a 48.2% lead. Data encryption shows 23881 versus 9115, a 61.8% margin, one of the largest gaps in the entire dataset. Extended instructions score 24017 versus 12354, a 48.6% difference. Find prime numbers shows 248 versus 47, an 81% gap, the single largest margin recorded.

Floating point math delivers 86929 versus 25336, a 70.9% lead. Integer math shows 71164 versus 40534, a 43% difference. The PassMark multithread score sits at 30659 versus 14018, a 54.3% margin. Physics simulation shows 2515 versus 755, a 70% gap. Random string sorting scores 37331 versus 19013, a 49.1% difference. Single-thread performance, where the AMD part is closest, shows 4293 versus 3778, a 12% margin.

The pattern across all tests is consistent: the Intel Arc G3 EXTREME leads by double digits in every category except the R23 multicore result, and even that remains a 16.6% deficit for AMD. The smallest gaps are in single-threaded workloads, where the AMD Zen 4 core design partially compensates for its lower core count. The largest gaps appear in parallel and specialized workloads, where the Intel chip's 14 cores and higher memory bandwidth dominate.

The Verdict

The recorded data supports a clear performance hierarchy. The Intel Arc G3 EXTREME outperforms the AMD Ryzen 3 8300G in every benchmark in the database, with an average benchmark score of 36699 versus 18169. The Intel chip also ranks higher overall, sitting at the 85th percentile of all CPUs compared to the AMD part's 72nd percentile.

The Intel processor's nearest rivals include the Intel Core Ultra 5 225 at a 0.6% higher average score, the AMD Ryzen 5 5600F at 0.7% higher, the AMD Ryzen 5 5500X3D at 0.9% higher, and the AMD Ryzen AI 7 PRO 450 at 1.1% higher. This places the Intel chip in a performance tier well above the AMD Ryzen 3 8300G, whose nearest rivals are the AMD Ryzen 7 5700U and Intel Core i7-1365U at essentially identical scores, with the Intel Core i7-9700 0.1% behind and the Intel Core i5-1334U 0.1% ahead.

For desktop builders, the AMD Ryzen 3 8300G offers AM5 socket compatibility, ECC memory support, and a 65 W TDP with Radeon 740M graphics. The Intel Arc G3 EXTREME targets mobile systems with a 25 W TDP, BGA 2540 socket, and Arc B390 graphics. The performance data does not favor the AMD part in any recorded workload, but the two chips serve different market segments, and the AMD part's desktop feature set remains relevant for that use case.
