# Greedfall on AMD Ryzen 5 8400F + Intel Arc B390: A Severely GPU-Limited Combination

The AMD Ryzen 5 8400F paired with the Intel Arc B390 delivers playable frame rates at 1080p in Greedfall, but the combination ranks in the bottom 12th percentile of all tested configurations, and the integrated-class GPU becomes the overwhelming bottleneck as resolution climbs. Benchmark data shows this combo achieves 60 FPS at 1080p High, but drops to just 25 FPS at 4K High — a clear indication that the Intel Arc B390, with its 7.680 TFLOPS of FP32 performance and 24 ROPs, cannot sustain the graphical load of this 2019 Action RPG at higher resolutions. The Ryzen 5 8400F, by contrast, demonstrates ample headroom, with a Cinebench R23 multi-core score of 20,851 that places it within 0.4% of the AMD EPYC 9474F in average benchmark scores.

GPU Role

The Intel Arc B390 is the decisive component in this pairing, and its specifications explain the measured performance ceiling. This integrated graphics processor, built on Intel's Xe3-LPG architecture with a 3 nm process, operates at a base clock of 300 MHz and boosts to 2500 MHz. It features 1,536 shading units, 48 texture mapping units, and just 24 render output units, with a pixel rate of 60.00 GPixel/s and a texture rate of 120.0 GTexel/s. These figures place it firmly in the entry-level segment — its 9th percentile ranking among all GPUs and its nearest rivals (all NVIDIA GT-series and 800M-class parts) confirm this.

Critically, the B390 uses system shared memory with a system-dependent bandwidth, meaning there is no dedicated VRAM pool. This architecture relies entirely on the host system's DDR5 memory, which the Ryzen 5 8400F supports in dual-channel configuration with 83.2 GB/s of bandwidth. In Greedfall, a game that demands substantial texture memory, this shared-memory arrangement likely contributes to the dramatic frame rate collapses at higher resolutions. The GPU's FP32 throughput of 7.680 TFLOPS and 12 ray tracing cores provide nominal capability, but the 24 ROPs severely limit fill-rate-bound scenarios.

The Ryzen 5 8400F, by contrast, is not the bottleneck. Its 6 cores and 12 threads based on Zen 4 (Phoenix) architecture, with a boost clock of 4.70 GHz, deliver a Cinebench R23 multi-core score of 20,851 and a single-core score of 2,943. Even in 3DMark's 16-thread test, the CPU scores 6,091, indicating substantial headroom. The data shows that Greedfall's frame rates scale almost entirely with GPU load: at 1080p Low, where the GPU has less work, the combo reaches 84 FPS; at 1080p Ultra, it falls to 38 FPS. This pattern — a 55% drop from Low to Ultra at the same resolution — is characteristic of a GPU-bound scenario. The CPU's 77th percentile ranking and its near-parity with the Ryzen 5 7500F (0.2% delta) suggest that swapping in a different GPU would yield far more performance improvement than upgrading the processor.

Resolution Scaling

The measured FPS data reveals a steep and consistent resolution penalty that confirms the GPU as the limiting component. At High settings, the combo delivers 60 FPS at 1080p, 42 FPS at 1440p, and 25 FPS at 4K. The transition from 1080p to 1440p represents a 30% performance loss, while the jump to 4K costs another 40% relative to 1440p — a cumulative 58% drop from 1080p. This scaling pattern is far steeper than what a CPU-bound system would exhibit, where resolution increases typically have minimal impact on frame rates.

At Low settings, the pattern persists: 84 FPS at 1080p, 58 FPS at 1440p, and 35 FPS at 4K. The 1080p-to-1440p drop is 31%, nearly identical to the High settings drop of 30%, which indicates that even at Low settings, the GPU is still the primary constraint. Notably, the Medium preset provides the only complete FPS range data: at 1080p Medium, the combo produces a minimum of 56 FPS, an average of 66 FPS, and a maximum of 76 FPS. At 1440p Medium, those figures fall to 39, 46, and 53 respectively, and at 4K Medium, they collapse to 23, 27, and 32.

The 4K results are uniformly unplayable across all settings — even Low yields only 35 FPS average, and Ultra produces a slideshow-like 16 FPS. The gap between Low and Ultra at 4K is just 19 FPS (35 vs. 16), whereas at 1080p the gap is 46 FPS (84 vs. 38). This compression of performance differences at 4K suggests that the GPU is hitting fundamental architectural limits, likely related to its 24 ROPs and shared memory subsystem, rather than simply running out of shader throughput. The data clearly shows that 1080p is the only viable resolution for this combination, and even there, users must make compromises between visual quality and frame rate stability.

How This Combo Ranks

In Greedfall, this combination of the AMD Ryzen 5 8400F and Intel Arc B390 ranks 2,595 out of 2,938 tested combos, placing it in the 12th percentile of all configurations. This ranking reflects the GPU's severe limitations more than the CPU's capabilities. To contextualize: the Ryzen 5 8400F alone sits in the 77th percentile of all CPUs, while the Arc B390 sits in the 9th percentile of all GPUs. The combo's final ranking of 2,595 is much closer to the GPU's percentile position, reinforcing that the B390 drags the overall system performance down dramatically.

The GPU's nearest rivals in benchmark scores — the GT 520MX, GeForce 800M, GT 625 OEM, and GT 710 — are all legacy or entry-level parts from previous generations, and the B390 only leads them by between 1.3% and 2.7%. These are not gaming-class GPUs by any modern standard, and their performance tier explains why the combo ranks so poorly in Greedfall, a game that was released in 2019 and has moderate system requirements. The CPU's nearest rivals, meanwhile, are far more capable parts: the Ryzen 5 7500F, Core i7-11850H, Core i7-13620H, and EPYC 9474F all score within 0.4% of the 8400F. This contrast between the two components' competitive positions is stark.

The rank of 2,595 out of 2,938 means that 343 tested combos performed worse than this one. While that places the combo just above the bottom 12% of systems, it is still a poor result for a 2024 CPU paired with a 2026 GPU. The data suggests that any mid-range discrete GPU from the past several years would substantially improve this ranking, as the CPU has demonstrated it can feed much higher frame rates — the 84 FPS at 1080p Low is likely still CPU-limited in minimum frame rate scenarios, but the GPU's texture rate of 120.0 GTexel/s and pixel rate of 60.00 GPixel/s cap what the system can deliver at higher settings.

Measured FPS Breakdown

The complete measured FPS dataset for Greedfall with this combo is as follows:

1920x1080:

• Low: 84 FPS average
• Medium: 66 FPS average (minimum 56, maximum 76)
• High: 60 FPS average
• Ultra: 38 FPS average

2560x1440:

• Low: 58 FPS average
• Medium: 46 FPS average (minimum 39, maximum 53)
• High: 42 FPS average
• Ultra: 27 FPS average

3840x2160:

• Low: 35 FPS average
• Medium: 27 FPS average (minimum 23, maximum 32)
• High: 25 FPS average
• Ultra: 16 FPS average

At 1080p, the combo provides a usable range of options. Low settings deliver 84 FPS, which is smooth and responsive, while Medium at 66 FPS and High at 60 FPS both clear the standard 60 FPS threshold. The Medium preset's minimum of 56 FPS indicates some frame time variance, but it remains playable. Ultra at 38 FPS is a significant drop and would likely feel stuttery in combat-heavy scenes.

Moving to 1440p, only Low (58 FPS) approaches the 60 FPS target, and it falls just short. Medium at 46 FPS and High at 42 FPS are playable but not ideal for a fast-paced Action RPG, while Ultra at 27 FPS is marginal. The Medium preset's range of 39-53 FPS shows that even the average figures can dip into uncomfortable territory.

At 4K, all results are below playable thresholds. Low at 35 FPS, Medium at 27 FPS (with a 23 FPS minimum), High at 25 FPS, and Ultra at 16 FPS all fail to provide a smooth experience. The 4K Medium data is the only resolution/settings combination with full min/max reporting, and the 23 FPS minimum confirms that the system struggles during demanding scenes. The 4K Ultra result of 16 FPS is essentially a static presentation.

Settings Recommendations

Based on the measured data, the optimal experience for this combo is 1080p with High settings. This preset delivers exactly 60 FPS average, which is the standard target for smooth gameplay, while providing significantly better visual fidelity than Low. The jump from Low (84 FPS) to High (60 FPS) sacrifices 24 FPS for improved textures, lighting, and effects, but remains at the playable threshold. Medium at 66 FPS offers a small frame rate cushion over High, but the visual difference between Medium and High in a 2019 RPG is worth the 6 FPS trade-off.

For users who prioritize frame rate stability over visual quality, 1080p Low at 84 FPS is the safest choice, providing ample headroom above 60 FPS and ensuring consistent performance. The Medium preset's minimum of 56 FPS suggests occasional dips below 60, whereas Low's higher average likely keeps minimums more comfortable. However, for the majority of players, 1080p High at exactly 60 FPS represents the best balance: it hits the performance target precisely while offering the game's intended visual presentation short of Ultra.

Ultra settings are not recommended at any resolution. At 1080p Ultra, the 38 FPS average is a 37% drop from High and would introduce noticeable stutter in a game that requires precise timing during combat. At 1440p Ultra (27 FPS) and 4K Ultra (16 FPS), the results are simply unplayable. The performance gap between High and Ultra (60 vs. 38 FPS at 1080p) is too large to justify the incremental visual improvements, which typically include higher shadow quality and post-processing effects.

For 1440p users, Low at 58 FPS is the only setting that approaches playability, but the 2 FPS deficit from 60 suggests occasional dips. Medium at 46 FPS is acceptable for slower exploration but will struggle in combat. Given the data, 1080p High is the clear recommendation: it is the highest settings preset that maintains a 60 FPS average, and it does so while avoiding the frame rate instability seen in the Medium preset's minimum readings. The combo's 2,595 rank out of 2,938 reflects that this is not a high-performance system, but the measured results show that a smooth Greedfall experience is achievable with the right settings choices.
