Fortnite

The AMD Ryzen 5 5500X3D and Intel Arc B570 pairing delivers a highly playable Fortnite experience at 1080p and 1440p, but the data shows a sharp performance cliff at 4K. Benchmark results indicate that the system’s frame rates scale predictably with resolution, yet the Ultra preset is uniformly demanding across all tested resolutions. This combination ranks 2178th out of 2740 tested combos for Fortnite, placing it in the lower-middle tier of the database, a position driven more by the GPU’s limits than the CPU’s capabilities.

Resolution Scaling

The measured FPS data reveals a clear and consistent pattern of performance degradation as resolution increases, with the most dramatic drops occurring between 1080p and 4K. At 1080p with Low settings, the system achieves 176 FPS, which drops to 112 FPS at 1440p (a 36% reduction) and then plummets to 59 FPS at 4K (a 47% drop from 1440p). This scaling pattern strongly indicates that the Intel Arc B570 becomes the limiting component at higher resolutions, as the frame rate loss is disproportionate to the pixel count increase.

The gap between 1080p and 1440p is substantial across all presets, suggesting that the GPU’s rendering throughput is the primary constraint. For instance, High settings produce 96 FPS at 1080p but only 61 FPS at 1440p, a 36% decline. Medium settings follow a similar trajectory, falling from 124 FPS to 79 FPS (36% lower). The transition from 1440p to 4K is even more punishing: High drops from 61 FPS to 32 FPS (48% lower), and Medium falls from 79 FPS to 42 FPS (47% lower).

The Ultra preset shows the worst absolute scaling. At 1080p, it manages 64 FPS, but this falls to 40 FPS at 1440p (37.5% drop) and then to 21 FPS at 4K (47.5% drop from 1440p). This suggests that Ultra settings introduce effects that heavily tax the GPU’s 10 GB memory buffer and 160-bit bus, particularly at 4K where the memory bandwidth of 380.0 GB/s is insufficient to maintain smooth frame pacing. The data implies that at 1080p, the Ryzen 5 5500X3D can keep the Arc B570 well-fed, but at 4K, the GPU’s raw compute (11.52 TFLOPS FP32) becomes the bottleneck.

Interestingly, the scaling from Low to Medium to High is relatively linear at each resolution, with roughly 20-30 FPS differences between presets. However, the jump from High to Ultra is disproportionately large: at 1080p, High runs at 96 FPS while Ultra runs at 64 FPS (33% slower), and at 4K, High runs at 32 FPS while Ultra runs at 21 FPS (34% slower). This indicates that Ultra enables features like higher draw distances and advanced shadow quality that are particularly expensive on the Xe2-HPG architecture.

FAQ

Q: What is the best resolution for this system to achieve 60 FPS or higher?

A: The data shows that 1440p with Medium settings averages 79 FPS, and 1080p with High settings averages 96 FPS. At 4K, no preset reaches 60 FPS; Low averages 59 FPS, which just misses the threshold.

Q: How does the Ultra preset compare to High in terms of frame rate cost?

A: Across all resolutions, Ultra is significantly more demanding. At 1080p, Ultra averages 64 FPS versus High’s 96 FPS, a 33% reduction. At 1440p, Ultra averages 40 FPS versus 61 FPS, and at 4K, Ultra averages 21 FPS versus 32 FPS.

Q: Is the CPU or GPU the limiting factor at 1080p?

A: At 1080p, the data suggests the GPU is still the primary limiter, as even High settings (96 FPS) leave headroom for the CPU. The Ryzen 5 5500X3D’s single-thread score of 2941 and multithread score of 20363 are sufficient to drive frame rates above 100 FPS in less demanding scenes, but the Arc B570’s performance caps the average.

Q: Can the system handle 4K gaming at all?

A: Yes, but only at Low settings, which averages 59 FPS. Medium drops to 42 FPS, High to 32 FPS, and Ultra to 21 FPS. The 4K results are consistently the weakest, with the GPU’s 10 GB VRAM and 380.0 GB/s bandwidth proving inadequate for higher presets.

Q: How does the Arc B570’s performance compare to its nearest rivals?

A: The Arc B570 has an average benchmark score of 20556, which is within 0.1% of the NVIDIA GeForce RTX 3070 Mobile (20534) and 0.1% below the Intel Arc A750 (20582). The data shows it also outperforms the NVIDIA Quadro M4000M by 0.4% and trails the AMD Radeon R9 M390X by 0.5%.

Q: What is the lowest FPS recorded in the measured data?

A: The lowest average FPS is 21, recorded at 4K with Ultra settings. The only minimum FPS values provided are for Medium settings: 35 FPS at 4K, 67 FPS at 1440p, and 106 FPS at 1080p.

Settings Recommendations

Based on the measured FPS rows, the optimal balance of visual quality and playability is achieved with High settings at 1440p. This configuration delivers an average of 61 FPS, which is acceptable for a battle royale where reaction time matters. The data shows that High at 1080p is smoother at 96 FPS, but 1440p offers a significant resolution upgrade with only a 35 FPS penalty, making it the sweet spot for this hardware.

For players prioritizing frame rate over visual fidelity, Low settings at 1080p provide the best experience with 176 FPS average. This is nearly three times the 4K Ultra performance and gives the system ample headroom for competitive play. The Medium preset at 1080p (124 FPS) is a reasonable middle ground, offering better textures and effects while maintaining a high refresh rate, though the minimum FPS of 106 suggests occasional dips.

The data indicates that Ultra settings should be avoided entirely. Even at 1080p, Ultra averages 64 FPS, which is below the High preset’s 96 FPS at the same resolution. The performance cost of Ultra is not justified by its visual improvements, especially given that the GPU’s 80 ROPs and 144 TMUs are not sufficient to handle the increased geometry and shading workload. For the best experience, players should stick to High at 1440p or Low at 1080p, depending on their display’s refresh rate and personal preference for smoothness versus sharpness.

Measured FPS Breakdown

At 1920x1080, the system delivers its strongest performance. Low settings average 176 FPS, which is the highest score in the entire dataset. Medium settings average 124 FPS, with a minimum of 106 FPS and a maximum of 143 FPS, indicating stable frame delivery. High settings average 96 FPS, while Ultra drops to 64 FPS. The 1080p results show a clear hierarchy, with each preset tier costing roughly 20-30 FPS compared to the previous one, except for the jump from High to Ultra, which costs 32 FPS.

At 2560x1440, performance remains playable but with noticeable reductions. Low settings average 112 FPS, which is still above the 60 FPS threshold for smooth gameplay. Medium settings average 79 FPS, with a minimum of 67 FPS and a maximum of 91 FPS, showing some variability but no severe stutters. High settings average 61 FPS, just above the playable threshold, while Ultra averages 40 FPS, which feels sluggish for a fast-paced game. The 1440p results show that the GPU’s pixel throughput (200.0 GPixel/s) is starting to become a limiting factor.

At 3840x2160, performance drops significantly across all presets. Low settings average 59 FPS, which is technically playable but below the 60 FPS standard. Medium settings average 42 FPS, with a minimum of 35 FPS and a maximum of 48 FPS, indicating noticeable frame drops during intense scenes. High settings average 32 FPS, and Ultra averages 21 FPS, both of which are too low for a competitive shooter. The 4K results demonstrate that the Arc B570’s 10 GB VRAM and 160-bit bus are insufficient for high-resolution textures and effects, as the bandwidth of 380.0 GB/s cannot keep up with the demand.

GPU Role

The Intel Arc B570’s specifications directly explain the measured FPS results, particularly at higher resolutions. The GPU has 2304 shading units, 144 TMUs, and 80 ROPs, with a base and boost clock of 2500 MHz. This configuration yields a texture rate of 360.0 GTexel/s and a pixel rate of 200.0 GPixel/s, which are respectable for a mid-range card but insufficient for 4K Ultra settings. The 11.52 TFLOPS FP32 compute is comparable to the NVIDIA GeForce RTX 3070 Mobile, as indicated by the 0.1% delta in benchmark scores.

The memory subsystem is a critical factor. With 10 GB of GDDR6 on a 160-bit bus, the bandwidth of 380.0 GB/s is modest by modern standards. The data shows that 4K performance suffers disproportionately, suggesting that the memory bandwidth is the primary bottleneck. At 1080p, the GPU has enough bandwidth to feed its cores efficiently, but at 4K, the larger frame buffer and higher-resolution textures exceed the memory’s ability to deliver data quickly.

The GPU’s benchmark scores provide context for its gaming performance. The Passmark G3D score of 14195 and the 3DMark Steel Nomad DX12 score of 2649 indicate that the card is capable of handling modern APIs, but the Passmark DirectX 11 score of 118 and DirectX 12 score of 72 show that it performs better in certain workloads than others. The Vulkan score of 96844 from Geekbench suggests strong driver support for Vulkan, which is relevant for Fortnite’s performance mode. The GPU’s 65th percentile ranking among all GPUs means it sits above average, but the measured FPS data shows that its real-world gaming performance is heavily dependent on resolution and settings.

CPU Role

The AMD Ryzen 5 5500X3D provides a solid foundation for gaming, with 6 cores and 12 threads based on the Zen 3 architecture. Its base clock of 3.00 GHz and boost clock of 4.00 GHz are modest, but the large 96 MB shared L3 cache is a significant advantage for gaming workloads. The CPU’s Passmark single-thread score of 2941 and multithread score of 20363 show that it performs well in both lightly-threaded and heavily-threaded tasks. The data indicates that the CPU is not the bottleneck in Fortnite, as even at 1080p with Low settings (176 FPS), the frame rate is limited by the GPU.

The CPU’s benchmark performance places it in the 85th percentile among all CPUs, with an average benchmark score of 37018. Its nearest rival, the AMD Ryzen 5 5600F, scores 36945, a difference of just 0.2%. This close grouping suggests that the 5500X3D offers similar computational performance to its peers, but the 96 MB L3 cache likely provides an edge in cache-sensitive games like Fortnite. The CPU’s memory support for DDR4 with dual-channel and 51.2 GB/s bandwidth is sufficient for this game, as the GPU’s memory subsystem is the more limiting factor.

The CPU’s architecture and cache are particularly well-suited for the game’s physics and rendering workloads. The Passmark physics score of 2282 and floating-point math score of 34511 indicate strong computational abilities, while the integer math score of 60033 shows efficient processing of game logic. The data suggests that the CPU can maintain high frame rates without becoming a constraint, as evidenced by the fact that 1080p Low achieves 176 FPS, which is nearly three times the 4K Ultra result. This performance disparity is entirely attributable to the GPU’s inability to keep pace at higher resolutions, confirming that the Ryzen 5 5500X3D is a capable partner for the Arc B570 in this title.
