Architecture Differences

The AMD Ryzen 5 8400F and Intel Arc G3 EXTREME represent fundamentally different design approaches. The AMD part belongs to the 8000 series and uses the Zen 4 architecture with the Phoenix codename. It is built on a 4 nm process at TSMC and packs 25,000 million transistors into a 178 mm² die. The Intel part uses the Panther Lake codename under the Arc G3 generation, fabricated on a 3 nm process at Intel's own foundry. The database does not record transistor count or die size for the Intel chip.

Core configuration differs sharply. The AMD chip offers 6 cores and 12 threads, relying on simultaneous multithreading to reach its thread count. The Intel chip provides 14 physical cores and 14 threads with no multithreading, meaning every thread maps to a dedicated core. Cache hierarchies also diverge: the AMD part has 64 KB of L1 per core and 1 MB of L2 per core, with 16 MB of shared L3. The Intel part has 192 KB of L1 per core and 2.5 MB of L2 per core, with 18 MB of shared L3.

Clock behavior shows a shared boost ceiling but different base points. Both processors reach 4.70 GHz boost clock. The AMD Ryzen 5 8400F starts at 4.20 GHz base, while the Intel Arc G3 EXTREME sits at 1.90 GHz base, a much lower idle point that aligns with its 25 W TDP. The AMD chip draws 65 W TDP and uses AMD Socket AM5, a desktop platform. The Intel part uses Intel BGA 2540, a mobile socket, and carries a 25 W TDP. The Intel part also supports PCIe Gen 5 with 4 CPU lanes, while the AMD chip uses PCIe Gen 4 with 20 lanes.

Memory architecture separates the two further. The AMD processor supports DDR5 with 83.2 GB/s bandwidth. The Intel processor supports LPDDR5X with 136.5 GB/s bandwidth. Neither supports ECC memory. The AMD chip has an unlocked multiplier, while the Intel chip is locked. The AMD part launched on 2024-03-31 with a launch MSRP of $170. The Intel part has a later release date of 2026-05-27 and no recorded launch MSRP. The AMD part is a desktop segment product, while the Intel part targets the mobile segment.

Head-to-Head Benchmarks

The head-to-head results paint a split picture: the Intel Arc G3 EXTREME dominates multi-threaded and math-heavy workloads, while the AMD Ryzen 5 8400F excels in single-core rendering and integer operations.

Starting with Cinebench, the AMD chip claims the two most decisive wins. In Cinebench R23 single-core, the AMD Ryzen 5 8400F scores 2943 against 1862 for the Intel part, a 58.1 percent advantage. That is the largest margin in the entire head-to-head set. In Cinebench R23 multi-core, the AMD chip scores 20851 versus 14655, a 42.3 percent lead. Cinebench R15 single-core also goes to AMD by 10.9 percent, with scores of 296 and 267.

The Intel part fights back in the older Cinebench versions. In Cinebench R15 multi-core, it scores 2192 versus 2101 for AMD, a 4.2 percent margin. Cinebench R20 shows a 20 percent swing in both directions: Intel wins multi-core with 10945 against 8757, and Intel also wins single-core with 1545 against 1236.

PassMark results heavily favor the Intel processor. The floating-point math test delivers the second-biggest margin of the entire comparison: Intel scores 86929 versus 46217 for AMD, a 46.8 percent advantage. PassMark physics shows a 47 percent gap, with Intel at 2515 and AMD at 1332. Find prime numbers gives Intel a 64.1 percent lead, scoring 248 versus 89. Data encryption goes to Intel by 30.3 percent, with 23881 against 16646. PassMark multi-thread shows Intel ahead by 20.5 percent, scoring 30659 versus 24389. Single-thread results favor Intel by 14.2 percent in both PassMark single-thread and single-thread tests, with scores of 4293 versus 3685.

The AMD processor wins PassMark integer math by a narrow 4 percent margin, scoring 74021 against 71164. That is the only PassMark victory for the AMD chip. Data compression goes to Intel by 6.2 percent, extended instructions by 7.7 percent, and random string sorting by 7.3 percent.

The final tally shows 13 wins for the Intel Arc G3 EXTREME and 4 wins for the AMD Ryzen 5 8400F. However, the two AMD wins in Cinebench R23 are the largest margins in the entire comparison, suggesting that the AMD chip has a specific strength in modern rendering workloads.

Both processors use dual-channel memory buses. Both lack ECC support. The AMD part has more PCIe lanes (20 versus 4), but the Intel part has a newer PCIe generation (Gen 5 versus Gen 4). The Intel chip integrates a GPU while the AMD chip does not. The AMD chip allows multiplier adjustment, the Intel chip does not.

The Verdict

The benchmark data supports a clear functional split between these two processors. The Intel Arc G3 EXTREME delivers superior aggregate performance, sitting at the 85th percentile with an average score of 36699, and it wins 13 of 17 head-to-head comparisons. Its strengths cluster in floating-point math, physics simulation, encryption, and multi-threaded throughput. The 46.8 percent lead in floating-point math and the 47 percent lead in physics indicate a processor suited to scientific computation, data processing, and heavily parallel workloads. The 14-core, 14-thread configuration with no multithreading provides raw core count that the PassMark multi-thread score of 30659 reflects.

The AMD Ryzen 5 8400F, in contrast, shows a narrower but highly specialized profile. Its 58.1 percent lead in Cinebench R23 single-core and 42.3 percent lead in Cinebench R23 multi-core demonstrate that in modern rendering workloads, the Zen 4 architecture with 6 cores and 12 threads outperforms the Intel part substantially. The 4 percent win in integer math adds a small but relevant edge for integer-heavy code. The AMD chip holds the 77th percentile overall with an average score of 25005, and its nearest rivals include the AMD Ryzen 5 7500F at a 0.2 percent delta and the Intel Core i7-11850H at a 0.3 percent delta. The Intel part's nearest rivals include the Intel Core Ultra 5 225 at a -0.6 percent delta and the AMD Ryzen 5 5600F at a -0.7 percent delta.

For desktop builders who prioritize Cinebench-style rendering, the AMD Ryzen 5 8400F is the data-backed choice. Its unlocked multiplier and desktop socket also make it a more flexible platform part. For users who need maximum throughput across a broader range of computational tasks, especially floating-point and physics workloads, the Intel Arc G3 EXTREME delivers higher scores in the majority of recorded tests. The Intel part also includes integrated graphics and a much lower 25 W TDP, which suits compact mobile systems. The AMD chip requires a discrete GPU but offers a higher base clock and more PCIe lanes for expansion. Neither processor supports ECC memory, and both share the same 4.70 GHz boost ceiling. The selection depends on whether the workload skews toward the modern rendering benchmarks where AMD wins decisively or toward the broader computational suite where Intel dominates.
