Fortnite

The AMD Ryzen 5 5600G paired with the Intel Arc B570 produces a spread of results in Fortnite that clearly maps the shifting balance between CPU and GPU workload as resolution changes. The data shows a system that is capable of high refresh rates at 1080p but becomes heavily GPU-bound at 4K, with the component roles becoming more distinct as settings and pixel counts rise.

Resolution Scaling

The measured FPS data shows a steep, predictable decline as resolution increases, but the shape of that decline reveals which component is doing the heavy lifting. At 1080p with Low settings, the combo averages 176 FPS. Moving to 1440p Low drops that to 112 FPS, a 36% reduction, and then to 4K Low it falls further to 59 FPS, a 47% drop from the 1440p figure. This pattern—large percentage losses at every step—indicates that the GPU is already the primary limiter even at lower settings, since the CPU has enough headroom to feed frames but the Arc B570 cannot maintain output as pixel count quadruples.

The scaling behavior under High settings tells a slightly different story. At 1080p High, the average is 96 FPS. At 1440p High, it falls to 61 FPS, a 36% reduction. At 4K High, it drops to 32 FPS, a 48% reduction from the 1440p result. The percentage losses are nearly identical to the Low settings curve, which suggests that the GPU is consistently the bottleneck across these presets; the CPU is not becoming more limiting at higher resolutions, because the workload shifts almost entirely to the graphics card once the pixel count increases.

The Medium settings row, which includes min and max FPS values, provides additional insight into frame pacing. At 1080p Medium, the average is 124 FPS with a min of 106 and max of 143. At 1440p Medium, the average drops to 79 FPS with min 67 and max 91. At 4K Medium, the average falls to 42 FPS with min 35 and max 48. The spread between min and max grows proportionally with resolution: roughly 37 FPS at 1080p, 24 FPS at 1440p, and 13 FPS at 4K. This narrowing range at higher resolutions indicates that the GPU is running at its sustained limit, reducing the variance that comes from CPU-driven frame spikes.

Ultra settings produce the most severe scaling. From 1080p Ultra at 64 FPS, the average drops to 40 FPS at 1440p (a 38% reduction) and then to 21 FPS at 4K (a 48% reduction). The 4K Ultra result of 21 FPS is barely playable, and the data makes clear that this resolution/preset combination is beyond the comfortable range of the Arc B570. The consistent 36-38% drop from 1080p to 1440p and 47-48% drop from 1440p to 4K across all presets strongly implies the GPU is the sole limiting factor at 1440p and above, with the CPU contributing little to the performance ceiling.

CPU Role

The Ryzen 5 5600G is a 6-core, 12-thread processor based on the Zen 3 architecture, running at a base clock of 3.90 GHz and a boost clock of 4.40 GHz. Its 16 MB of L3 cache and dual-channel DDR4 memory support with 51.2 GB/s bandwidth are sufficient for Fortnite's engine, which does not heavily stress more than a few cores. The CPU's benchmark scores indicate it is a mid-range part: its Cinebench R23 multi-core score is 10551 and single-core is 1409, while its Geekbench single-core is 1801. In the database of all CPUs, it sits at the 74th percentile, with an average benchmark score of 21088. Its nearest rivals are the Intel Core i3-1220P (0.1% higher score), Intel Core Ultra 7 256V (0.1% lower), AMD Ryzen 5 7530U (0.2% lower), and Intel Core Ultra 7 155U (0.4% lower). This places it in a competitive band where minor score differences separate it from other mainstream parts.

The measured FPS data suggests the CPU is not the primary constraint in this pairing. At 1080p Low, the combo reaches 176 FPS, which is well above the refresh rate of most monitors, and even at 1080p High it maintains 96 FPS. The 3DMark single-thread score of 872 and multi-thread score of 5455 indicate that the CPU can handle the draw call and physics workloads Fortnite generates. However, the CPU's integrated Radeon Vega 7 graphics is irrelevant when paired with a discrete GPU, and its role is limited to feeding the Arc B570 with frame data. The fact that FPS drops by nearly half when moving from 1080p to 4K at the same settings proves that the CPU has headroom left, since a CPU-bound scenario would show more stable FPS across resolutions.

The data also shows that the CPU's multi-threading capability is underutilized. The 6-core/12-thread configuration can handle background tasks while gaming, but Fortnite's performance scaling with this GPU is purely resolution-driven. The passmark multi-thread score of 19717 and passmark single-thread score of 3177 suggest a balanced processor, but the game's results do not show any sudden FPS cliffs that would indicate a core-count or thread-count limitation. In practical terms, the Ryzen 5 5600G is adequate for this GPU at 1080p and 1440p, but at 4K, it is clearly the GPU that determines the final frame rate.

GPU Role

The Intel Arc B570 is the dominant factor in this combo's Fortnite performance. It features 10 GB of GDDR6 memory on a 160-bit bus with 380.0 GB/s bandwidth, which is ample for the game at 1080p and 1440p, though 4K Ultra may approach the memory capacity limit. The GPU's clocks are set at a base and boost of 2500 MHz, with memory running at 2375 MHz (19 Gbps effective). Its compute configuration includes 2304 shading units, 144 TMUs, and 80 ROPs, with 18 ray tracing cores. The FP32 throughput is 11.52 TFLOPS, which is moderate for a modern discrete GPU. The GPU's benchmark scores show a passmark G3D score of 14195 and a 3DMark Steel Nomad DX12 score of 2649, placing it at the 65th percentile among all GPUs with an average benchmark score of 20556. Its nearest rivals are the NVIDIA GeForce RTX 3070 Mobile (0.1% higher), Intel Arc A750 (0.1% lower), NVIDIA Quadro M4000M (0.4% higher), and AMD Radeon R9 M390X (0.5% lower).

The measured FPS data clearly shows the GPU's limits. At 1080p Low, the 176 FPS average demonstrates that the Arc B570 can push high frame rates when the workload is light. But at 4K Ultra, the 21 FPS average shows that the GPU is overwhelmed by the combination of high resolution and heavy settings. The memory bandwidth of 380 GB/s is a likely constraint at 4K, as the increased pixel count demands more data throughput for textures and shading. The GPU's 10 GB VRAM is sufficient for 1080p and 1440p, but at 4K Ultra, the texture data may exceed the capacity, causing the GPU to be the clear bottleneck.

The scaling from Low to Ultra at each resolution further highlights the GPU's role. At 1080p, going from Low (176 FPS) to Ultra (64 FPS) results in a 64% reduction. At 1440p, the drop from Low (112 FPS) to Ultra (40 FPS) is also 64%. At 4K, the drop from Low (59 FPS) to Ultra (21 FPS) is 64% as well. This consistent percentage reduction across resolutions indicates that the GPU's shading and texture units are the limiting factor, regardless of the pixel count. The CPU does not interfere with this scaling, as the same reduction pattern holds even when the CPU has more headroom at lower resolutions. The GPU is the sole determinant of performance in this pairing, and its capabilities define what is playable.

At 1080p, the combo delivers 176 FPS on Low, 124 FPS on Medium, 96 FPS on High, and 64 FPS on Ultra. The Medium preset includes additional frame data, with a minimum of 106 FPS and a maximum of 143 FPS, indicating a 37 FPS range. This is the highest performance tier for this pairing, and every preset except Ultra maintains an average above 90 FPS.

At 1440p, the results show a clear step down. Low averages 112 FPS, Medium averages 79 FPS with a min of 67 and max of 91, High averages 61 FPS, and Ultra averages 40 FPS. Only Low and Medium exceed the 60 FPS threshold, while High is just barely at it and Ultra falls below. The frame range at Medium narrows to 24 FPS, showing less variance than at 1080p.

At 4K, the performance drops significantly. Low averages 59 FPS, which is just under the 60 FPS target. Medium averages 42 FPS with a min of 35 and max of 48, a 13 FPS range. High averages 32 FPS, and Ultra averages 21 FPS. None of these presets provide a smooth experience, and even Low is borderline. The data shows a consistent pattern: each resolution step reduces FPS by roughly one-third to one-half, and each settings step reduces FPS by roughly 25-35% from the previous preset. The 4K Ultra result of 21 FPS is the lowest measured, and the 1080p Low result of 176 FPS is the highest.

Settings Recommendations

The measured data suggests that the choice of settings depends heavily on the target resolution and refresh rate. At 1080p, the Low preset at 176 FPS is ideal for competitive play on a high-refresh monitor, but the Medium preset at 124 FPS offers a better balance between visual quality and performance. The High preset at 96 FPS is still smooth for most displays, while Ultra at 64 FPS is playable but does not provide the headroom needed for a 144Hz panel. For the best experience at 1080p, the Medium preset is recommended, as it delivers 124 FPS with a min of 106 FPS, ensuring no drops below the 60 FPS threshold.

At 1440p, the situation is more constrained. The Low preset at 112 FPS is the only option that provides a comfortable margin above 60 FPS, while the Medium preset at 79 FPS is also viable. The High preset at 61 FPS is marginal, and the Ultra preset at 40 FPS is not recommended for smooth gameplay. The data indicates that 1440p Medium is the optimal choice, offering 79 FPS with a min of 67 FPS, which keeps the experience above 60 FPS even during heavy scenes. This preset provides a good balance of visual fidelity and performance.

At 4K, the recommendations are more limited. The Low preset at 59 FPS is the only option that approaches playable frame rates, and even that is below the 60 FPS target. The Medium preset at 42 FPS is playable but not smooth, and the High and Ultra presets at 32 FPS and 21 FPS respectively are not recommended for any serious gameplay. For users insisting on 4K, the Low preset is the only viable choice, but the data suggests that dropping to 1440p Medium or 1080p Medium would provide a significantly better experience. The measured rows clearly show that the best experience per the data is at 1080p Medium or 1440p Low, depending on whether visual quality or frame rate is prioritized.

How This Combo Ranks

In the database of tested combos for Fortnite, this pairing of the AMD Ryzen 5 5600G and Intel Arc B570 ranks 2178 out of 2740 total combinations. This places it in the lower half of all tested systems, which is consistent with the measured FPS data showing that it struggles at higher resolutions and settings. The rank of 2178 out of 2740 means that roughly 20% of tested combos perform worse, while 80% perform better. This is a mid-to-low tier ranking, reflecting the fact that the Arc B570 is a mid-range GPU and the Ryzen 5 5600G is a budget-to-mainstream CPU.

The combo's rank is driven primarily by the GPU's limitations at 4K and its moderate performance at 1440p. The CPU's 74th percentile standing among all CPUs is respectable, but it does not boost the overall ranking because the GPU is the bottleneck. The data shows that this system is best suited for 1080p gaming, where it can deliver high frame rates, but it falls behind in the database rankings because many other combos can sustain higher FPS at 1440p or 4K. The 2178th rank out of 2740 places it just above the bottom quartile, meaning there are many stronger pairings available. However, the measured FPS at 1080p Low (176 FPS) and 1080p Medium (124 FPS) show that this combo is perfectly capable for competitive Fortnite at the most common resolution, even if it does not rank highly against more powerful systems.
