Greedfall

The Intel Core i5-9400 and AMD Radeon RX 580 combination ranks 1568th out of 1705 tested combos in Greedfall, placing it in the lower tier of systems capable of running the game. This position, in the 8th percentile of all combinations, suggests a pairing that can handle the game at playable framerates only under specific conditions, with a significant performance gap separating it from mid-range and high-end setups. The data indicates a system that is fundamentally constrained by its GPU, though the CPU also presents limitations that become apparent at lower resolutions.

How This Combo Ranks

The 1568th rank out of 1705 combos places this pairing firmly in the lower quartile of tested systems, indicating that a large majority of other hardware combinations deliver superior performance in Greedfall. This is not a surprising result given the component selection, as the RX 580 is an older GPU architecture, and the i5-9400 is a mid-range processor from the Coffee Lake generation. The rank suggests that while the game is playable, it will not deliver a high-refresh-rate experience, nor will it handle high graphical presets at demanding resolutions. Benchmark results indicate the combo's performance is heavily influenced by the GPU's raw compute capabilities, which are modest by current standards. The practical implication is that users of this system should expect to tune settings carefully, prioritizing framerate over visual fidelity, especially at 1440p and above. The data shows a clear ceiling on performance that cannot be overcome by software tweaks alone, given the hardware's inherent limits.

GPU Role

The AMD Radeon RX 580 is the primary bottleneck in this pairing for Greedfall, and its specifications confirm this. The GPU operates with a base clock of 1257 MHz and a boost clock of 1340 MHz, which are modest figures that limit its peak throughput. Its 8 GB of GDDR5 memory on a 256-bit bus provides a bandwidth of 256.0 GB/s, which is sufficient for the game's textures but not excessive. The card's 2304 shading units and 144 texture mapping units deliver a theoretical FP32 performance of 6.175 TFLOPS, which is the raw compute power that dictates how quickly the GPU can process the game's geometry and effects. The GPU sits at the 53rd percentile versus all GPUs, with an average benchmark score of 13559. Its nearest rivals include the NVIDIA GeForce GTX 570 with a score of 13564 and a delta of 0%, and the NVIDIA GeForce GTX 950 with a score of 13549 and a delta of 0.1%. This close grouping indicates that the RX 580's performance is essentially on par with those older cards, which explains its struggle to maintain high framerates in a demanding title like Greedfall. The 8 GB VRAM capacity is adequate for the game's assets, but the GPU's core architecture is not fast enough to push high pixel counts effectively.

Resolution Scaling

The measured FPS data shows a clear and predictable scaling pattern as resolution increases, which strongly suggests that the GPU is the limiting factor in this configuration. At 1080p with Low settings, the combo achieves an average of 82 FPS, which is a playable framerate. Dropping to 1440p Low reduces the average to 56.7 FPS, a 30.9% decrease, and at 4K Low, the average falls to 34.7 FPS, a 57.7% decrease from the 1080p baseline. This steep decline in performance with each resolution step is characteristic of a GPU-bound scenario, where the pixel fill rate and memory bandwidth of the RX 580 become overwhelmed. The pattern holds across all settings; for example, at High settings, the framerate drops from 58.2 FPS at 1080p to 40.7 FPS at 1440p and then to 22.1 FPS at 4K. The data indicates that while the CPU plays a role, the GPU's inability to handle the increased pixel workload at higher resolutions is the dominant factor in the performance degradation. Users targeting 4K will find the experience largely unplayable, while 1440p requires significant settings compromises, and 1080p remains the only resolution where the combo can deliver consistently smooth gameplay.

Measured FPS Breakdown

At 1920x1080, the combo delivers its best results, with a Low settings average of 82 FPS. Medium settings yield 62.9 FPS, and High settings produce 58.2 FPS. Ultra settings, however, cause a significant drop to 38.5 FPS, which is below the ideal threshold for smooth gameplay in an action RPG. The data shows a clear trend: the framerate is highly sensitive to the graphical preset, with a 53.1% difference between Low and Ultra settings. Moving to 2560x1440, the performance degrades substantially. Low settings average 56.7 FPS, which is playable, but Medium drops to 45.5 FPS, and High falls to 40.7 FPS. Ultra at 1440p is the weakest point, with an average of just 27.7 FPS, making it unsuitable for a fluid experience. At 3840x2160, the combo is largely out of its depth. Low settings manage 34.7 FPS, Medium drops to 24.4 FPS, High to 22.1 FPS, and Ultra plummets to 16.4 FPS. These numbers clearly indicate that 4K gaming is not viable with this hardware, and even the lowest settings fail to reach a consistent 30 FPS. The measured data underscores that the RX 580 is capable of handling the game at 1080p with reduced settings, but struggles at 1440p and is overwhelmed at 4K.

CPU Role

The Intel Core i5-9400 provides the processing foundation for this combo, and its specifications suggest it is less of a bottleneck than the GPU, but still a limiting factor at lower resolutions. The CPU features 6 cores and 6 threads, with a base clock of 2.90 GHz and a boost clock of 4.10 GHz. This configuration is adequate for Greedfall, which is not a heavily threaded title, but the lack of hyper-threading could become a constraint in demanding scenes. The CPU's benchmark scores place it at the 50th percentile versus all CPUs, with an average benchmark score of 2305. Its nearest rivals include the Intel Core i3-10305 with a score of 2300 and a delta of 0.2%, and the Intel Core i3-1125G4 with a score of 2299 and a delta of 0.2%. This close grouping indicates that the i5-9400's performance is nearly identical to those lower-tier chips, highlighting its mid-range positioning. In Greedfall, the CPU's role is most evident at 1080p with Low settings, where the GPU is not fully saturated, and the processor must work harder to feed frames. The data shows that at 1080p Low, the system achieves 82 FPS, which is a good result, but the CPU's 6-thread limit may prevent higher framerates if the GPU were faster. The 9 MB of shared L3 cache and dual-channel DDR4 memory support with 42.7 GB/s bandwidth provide adequate data flow for the game, but the CPU's overall compute capability, as reflected in its Cinebench R23 multicore score of 7969, is a modest figure that underscores its limitations in more CPU-intensive scenarios. The benchmark results indicate that while the CPU is not the primary constraint at higher resolutions, it can be a secondary bottleneck that prevents the system from achieving maximum performance in less GPU-demanding settings.
