AMD Ryzen 5 8400F vs Intel Arc G3 Comparison

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark results between the AMD Ryzen 5 8400F and the Intel Arc G3. The head-to-head section is empty, with zero wins recorded for either part. The Ryzen 5 8400F has a full suite of 23 recorded benchmark scores, while the Intel Arc G3 has no recorded benchmark entries at all. This absence of comparative data means any performance assessment must rely on the architectural specifications and the Ryzen 5 8400F's absolute scores, interpreted against its own nearest rivals rather than against the Intel part.

The Ryzen 5 8400F's average benchmark score of 25005 places it at the 77th percentile among all CPUs in the database. Its nearest rivals, based on average score, are the AMD Ryzen 5 7500F at 24964 (0.2% behind), the Intel Core i7-11850H at 24935 (0.3% behind), the Intel Core i7-13620H at 24911 (0.4% behind), and the AMD EPYC 9474F at 25103 (0.4% ahead). These deltas are narrow, indicating the 8400F sits in a tightly contested performance band.

Looking at the Ryzen 5 8400F's specific workloads, the Cinebench R23 multicore score of 20851 and single-core score of 2943 provide the clearest picture of its compute capability. The multicore result is roughly seven times the single-core figure, reflecting the benefit of its 6-core, 12-thread configuration. In 3DMark threaded tests, the max-threads score of 6165 is only slightly above the 16-thread score of 6091, suggesting the processor's scaling saturates near its full thread count. The 2-thread score of 1874 and 4-thread score of 3563 show a near-linear scaling at low thread counts, with 4-thread performance at roughly 1.9 times the 2-thread result.

PassMark results reinforce the pattern. The multithread score of 24389, integer math score of 74021, and floating-point math score of 46217 all indicate strong throughput for a 6-core desktop part. Data compression (288158) and random string sorting (34604) are notably high, while find prime numbers (89) and physics (1332) are comparatively modest. The single-thread PassMark score of 3685 is consistent with the Cinebench R23 single-core result, confirming solid per-core performance.

Because the Intel Arc G3 has no benchmark scores, no direct comparison of compute performance, efficiency, or workload-specific behavior can be made from the recorded data. The database does not allow statements such as "the 8400F is X% faster than the Arc G3" because no such measurements exist. The only comparisons available are those between the 8400F and its nearest rivals, all of which fall within a 0.8 percentage-point band in average score.

Architecture Differences

The two processors represent fundamentally different design philosophies and market targets. The AMD Ryzen 5 8400F is a desktop part built on the Zen 4 architecture with the codename Phoenix, manufactured by TSMC on a 4 nm process node. It uses the AMD Socket AM5 and belongs to the 8000 series Ryzen 5 generation. The Intel Arc G3 is a mobile part with the codename Panther Lake, manufactured by Intel on a 3 nm process node, using the Intel BGA 2540 socket. It belongs to the Arc G3 generation.

Core and thread counts differ substantially. The Ryzen 5 8400F has 6 cores and 12 threads, while the Intel Arc G3 has 14 cores and 14 threads. The Arc G3's thread count equals its core count, indicating no simultaneous multithreading, whereas the 8400F doubles its threads over cores. The Arc G3's 14 cores are a larger physical count, but the 8400F's 12 threads provide more logical execution contexts than its 6 cores would suggest.

Clock speeds favor the AMD part. The 8400F has a base clock of 4.20 GHz and a boost clock of 4.70 GHz. The Arc G3 has a base clock of 1.90 GHz and a boost clock of 4.60 GHz. The base clock difference is large (4.20 versus 1.90 GHz), while the boost clocks are close (4.70 versus 4.60 GHz). This suggests the AMD processor maintains higher sustained frequencies, while the Intel part relies on boost behavior to approach similar peak speeds.

Cache hierarchies differ in both size and organization. The 8400F has 64 KB of L1 cache per core, 1 MB of L2 cache per core, and 16 MB of shared L3 cache. The Arc G3 has 192 KB of L1 per core, 2.5 MB of L2 per core, and 18 MB of shared L3 cache. The Intel part has larger per-core L1 and L2 caches, and a slightly larger L3 pool. Total cache per core is substantially higher on the Arc G3, though the 8400F's smaller core count means its aggregate cache is lower.

Memory support diverges as well. The 8400F supports DDR5 memory with a dual-channel bus and a recorded memory bandwidth of 83.2 GB/s. The Arc G3 supports LPDDR5X memory, also dual-channel, with a recorded memory bandwidth of 136.5 GB/s. The Intel part's memory bandwidth is roughly 64% higher than the AMD part's, a significant advantage for memory-bound workloads. Neither processor supports ECC memory.

PCIe connectivity differs. The 8400F provides PCIe Gen 4 with 20 lanes (CPU only), while the Arc G3 provides PCIe Gen 5 with 4 lanes (CPU only). The AMD part has far more lanes, but the Intel part uses a newer Gen 5 interface. The Arc G3 includes integrated graphics (Arc B370), while the 8400F has no integrated graphics (N/A). The Intel part is a mobile processor with a 25 W TDP, while the AMD part is a desktop processor with a 65 W TDP. The 8400F has an unlocked multiplier; the Arc G3 does not. The 8400F has a launch MSRP of $170; the Arc G3 has no recorded launch MSRP.

The architecture field is listed as Zen 4 for the 8400F and null for the Arc G3, meaning the database does not assign a specific architecture name to the Intel part. Transistor count (25,000 million for the 8400F) and die size (178 mm² for the 8400F) are not recorded for the Arc G3.

The Verdict

The data supports distinct selection criteria for each processor based on market segment and workload profile. The AMD Ryzen 5 8400F is a desktop processor with an unlocked multiplier, a 65 W TDP, and PCIe Gen 4 with 20 lanes. It has a launch MSRP of $170 and is in active production. Its benchmark scores, including a Cinebench R23 multicore score of 20851 and a PassMark multithread score of 24389, place it at the 77th percentile among all CPUs. The 8400F is suitable for desktop builds where overclocking, PCIe lane count, and a lower launch price are priorities.

The Intel Arc G3 is a mobile processor with a 25 W TDP, integrated Arc B370 graphics, and PCIe Gen 5 with 4 lanes. It has 14 cores and a higher memory bandwidth of 136.5 GB/s. It does not have an unlocked multiplier and has no recorded launch MSRP. The database records no benchmark scores for the Arc G3, so its performance position cannot be quantified against the 8400F or any other processor. The Arc G3's percentile ranking is 50, and its average benchmark score is 0.

For a desktop user who needs a 6-core, 12-thread processor with strong recorded single-thread and multicore performance, the Ryzen 5 8400F is the only option with measured data. For a mobile user who needs integrated graphics, a larger core count, and higher memory bandwidth, the Intel Arc G3 offers those specifications, but no benchmark evidence exists to validate its performance. The 8400F's nearest rivals are all within 0.4% of its average score, indicating a tightly competitive desktop segment. The Arc G3 has no nearest rivals recorded, so its competitive position is undefined.

The release dates differ by more than two years, with the 8400F released on 2024-03-31 and the Arc G3 on 2026-05-27. The 8400F's 4 nm TSMC process versus the Arc G3's 3 nm Intel process reflects a newer manufacturing technology for the Intel part. The 8400F's 178 mm² die size and 25,000 million transistors are not available for comparison because the Arc G3 has no recorded values for either metric.

The verdict from the recorded data is straightforward: the Ryzen 5 8400F is a fully characterized desktop processor with extensive benchmark coverage, while the Intel Arc G3 is a specification-only mobile part with no measured performance data. Any purchasing decision between the two would depend on form factor, platform, and feature requirements, but only the 8400F has empirical evidence to support performance claims.
