Fivem

The AMD Ryzen 5 8400F paired with the Intel Arc B580 delivers a playable but demanding experience in Fivem, with performance scaling that clearly favors lower resolutions. The data shows a system capable of high refresh rates at 1080p with tuned settings, but one that requires significant compromises to maintain smooth gameplay at 4K.

Resolution Scaling

The measured FPS numbers reveal how heavily Fivem's workload shifts between resolutions. At 1080p with Low settings, the combo achieves 151.6 FPS, which drops to 98.8 FPS at 1440p and further to 52.4 FPS at 4K. This represents a 34.8% performance loss from 1080p to 1440p, and a 65.4% loss from 1080p to 4K. The scaling pattern indicates that at lower resolutions, the CPU and GPU are both heavily utilized, but as resolution increases, the GPU becomes the primary bottleneck.

The gap between Low and Ultra settings widens dramatically at higher resolutions. At 1080p, the difference between Low (151.6 FPS) and Ultra (73.7 FPS) is 77.9 FPS. At 1440p, that gap shrinks to 51 FPS, and at 4K, it narrows to 27 FPS. This compression of the settings range at 4K is a classic sign of GPU limitation, when the GPU is saturated, changing settings has less impact on overall performance.

The most telling data point is the 4K Ultra result of 25.4 FPS, which is below playable thresholds. The 4K High result of 37.6 FPS is only marginally better, while 4K Medium (44.4 FPS) and 4K Low (52.4 FPS) remain the only viable options for 4K gaming. The scaling from 1440p to 4K at High settings shows a 37.3 FPS drop (60.3 to 37.6), indicating that 1440p is the practical ceiling for this combo with quality settings.

GPU Role

The Intel Arc B580 brings 12 GB of GDDR6 memory across a 192-bit bus, delivering 456.0 GB/s of bandwidth. This memory configuration is sufficient for Fivem's asset streaming at 1440p, but the 4K Ultra result of 25.4 FPS suggests that both memory bandwidth and raw compute are stressed at that resolution. The GPU's boost clock is fixed at 2670 MHz, which matches the base clock, indicating a steady-state operational profile.

The GPU's compute throughput is rated at 13.67 TFLOPS FP32, with 2560 shading units and 80 ROPs. These specifications translate into the measured results, where the GPU shows strong 1080p performance but struggles to maintain 60 FPS at 4K. The pixel rate of 213.6 GPixel/s and texture rate of 427.2 GTexel/s are respectable for the segment, yet the 4K data shows the GPU hitting its limits when combined with Ultra settings.

The B580's 20 ray tracing cores are present, but Fivem's workload does not appear to leverage them heavily based on the performance patterns. The GPU's 66th percentile ranking among all GPUs, with an average benchmark score of 23021, places it near the NVIDIA GeForce RTX 4060 (23181, deltaPct -0.7%) and slightly ahead of the AMD Radeon 760M (22999, deltaPct 0.1%). This competitive positioning explains why the combo performs admirably at 1080p but falls short at 4K.

Settings Recommendations

The measured data provides clear guidance for optimizing the experience. At 1080p, Medium settings deliver 119.5 FPS, which is a 21.2% improvement over High (97.9 FPS) while maintaining visual quality. Low settings at 1080p push the frame rate to 151.6 FPS, which is ideal for competitive play, but the jump from Medium to Low is 32.1 FPS, a significant gain for those prioritizing frame rate.

For 1440p, the recommendation shifts to Medium settings at 79.7 FPS. This represents a 32.1% improvement over High (60.3 FPS) and keeps the experience smooth. Ultra at 1440p (47.8 FPS) is borderline, while Low (98.8 FPS) is the choice for maximum fluidity. The 1440p Medium result is the sweet spot, offering a balance between visual fidelity and performance.

At 4K, the data suggests Low settings are the only practical choice, yielding 52.4 FPS. Medium (44.4 FPS) and High (37.6 FPS) are playable but below the 60 FPS threshold, while Ultra (25.4 FPS) is not recommended. The 27 FPS gap between Low and Ultra at 4K demonstrates the diminishing returns of quality settings at this resolution.

Measured FPS Breakdown

At 1920x1080, the combo delivers a full range of results. Low settings produce 151.6 FPS, Medium 119.5 FPS, High 97.9 FPS, and Ultra 73.7 FPS. The progression from Low to Ultra shows a consistent 20-25 FPS drop per settings tier, indicating balanced scaling. The 1080p data confirms this is the native resolution for this pairing.

Moving to 2560x1440, performance scales predictably. Low yields 98.8 FPS, Medium 79.7 FPS, High 60.3 FPS, and Ultra 47.8 FPS. The drop from Low to Medium is 19.1 FPS, Medium to High is 19.4 FPS, and High to Ultra is 12.5 FPS. The smaller drop at the High-to-Ultra transition suggests the GPU is becoming more constrained.

At 3840x2160, the results compress significantly. Low produces 52.4 FPS, Medium 44.4 FPS, High 37.6 FPS, and Ultra 25.4 FPS. The differences between tiers are 8 FPS (Low to Medium), 6.8 FPS (Medium to High), and 12.2 FPS (High to Ultra). The Ultra tier's disproportionate drop indicates a hard performance cliff, likely due to memory bandwidth saturation.

How This Combo Ranks

The AMD Ryzen 5 8400F + Intel Arc B580 combination ranks 1409 out of 1792 tested combos in Fivem, placing it in the 78th percentile. This ranking reflects the CPU's 82nd percentile standing among all CPUs, with an average benchmark score of 25064. The CPU's nearest rivals include the AMD Ryzen 7 2700X (25057, deltaPct 0%) and the AMD Ryzen 5 7500F (24993, deltaPct 0.3%), showing the 8400F is essentially tied with these alternatives.

The GPU's 66th percentile ranking (average score 23021) is the weaker component in this pairing. The B580 sits just below the GeForce RTX 4060 (23181, deltaPct -0.7%) and slightly above the NVIDIA P106-100 (22950, deltaPct 0.3%). This GPU performance tier explains why the combo ranks in the lower-middle of the overall distribution despite the CPU's solid showing.

In practical terms, the combo's 1080p results are competitive with mid-range systems, but the 4K data shows this is not a 4K-capable configuration. The rank of 1409 out of 1792 indicates that most tested combos outperform this pairing in Fivem, with the CPU's strength partially compensating for the GPU's limitations.
