Fortnite

Fortnite on the AMD Ryzen 9 5950X with the Intel Arc B570 presents a fascinating study in balance and bottlenecking. The data shows a combination that can deliver high refresh rates at 1080p with the right settings, but struggles to maintain playable frames at 4K Ultra. This analysis breaks down the measured performance across resolutions and settings, offering clear guidance on how to configure this specific hardware pairing for the best experience based strictly on the benchmark results.

Settings Recommendations

The benchmark data clearly indicates that the "Low" preset is the only setting tier that allows this CPU/GPU combination to fully stretch its legs at every resolution. At 1920x1080, Low produces an average of 176 FPS, which is a massive jump over the next best option. The "Medium" preset at 1080p yields 124 FPS, a solid 52 FPS lower than Low, while "High" drops further to 96 FPS, and "Ultra" falls to just 64 FPS. For competitive play, the Low preset at 1080p is the only choice, as the 176 FPS average provides a substantial advantage over the 124 FPS of Medium.

At 2560x1440, the story remains consistent. Low delivers 112 FPS, which is still comfortably above the 60 FPS threshold for smooth gameplay. Medium at 1440p drops to 79 FPS, which is playable, but the 33 FPS difference between Low and Medium is significant. High at 1440p is at 61 FPS, just scraping by, while Ultra falls to 40 FPS, which is not a smooth experience for a fast-paced Battle Royale. For 1440p users, the data suggests that Low is the recommended preset for maintaining high refresh rates, while Medium is the highest setting that keeps the average FPS above the 60 FPS mark.

The situation changes dramatically at 3840x2160. Here, even Low only manages 59 FPS, which is borderline playable. Medium drops to 42 FPS, High to 32 FPS, and Ultra to a nearly unplayable 21 FPS. The data indicates that 4K is not a viable resolution for this combo if you want a fluid experience, as even the lowest settings cannot consistently hit 60 FPS. The recommendation for 4K is to either stick with Low and accept the sub-60 FPS average, or more practically, to consider a lower resolution like 1440p for a better experience.

The overall recommendation is clear: prioritize the Low preset with this hardware. The performance scaling suggests that the GPU is the limiting factor at higher settings, and the massive FPS gains from Low make it the most practical choice for both competitive and casual play at 1080p and 1440p.

GPU Role

The Intel Arc B570 is the primary driver of the performance differences seen across settings. It features 10 GB of GDDR6 memory on a 160-bit bus, delivering a bandwidth of 380.0 GB/s. The GPU is based on the Xe2-HPG architecture (Battlemage) and is built on a 5 nm process by TSMC. Its 2304 shading units are clocked at a consistent 2500 MHz for both base and boost, which is a unique characteristic that suggests consistent power delivery.

The GPU's performance percentile is 65, placing it in the mid-range tier. Its nearest rivals, based on average benchmark scores, include the NVIDIA GeForce RTX 3070 Mobile with a 0.1% delta, and the Intel Arc A750 with a -0.1% delta. This context is crucial; the B570 is performing at a level comparable to a last-generation mobile high-end GPU and its direct predecessor. In Fortnite, this translates to the GPU struggling as settings increase. The data shows a steep drop-off from Low to Ultra at every resolution, which points to the GPU's shading units and memory bandwidth being overwhelmed by the increased visual complexity. For example, at 1080p, the drop from Low (176 FPS) to Ultra (64 FPS) is a 112 FPS loss, attributing almost all of this to the GPU's inability to handle the higher-quality textures, effects, and draw distances.

The 10 GB VRAM is not the primary bottleneck here, as even at 4K, the issue is more about raw processing power than memory capacity. The consistent clock speed of 2500 MHz suggests the GPU is running at its limit across all tests, and the performance degradation is a direct result of the workload increasing beyond what the compute units can handle. In this pairing, the Arc B570 is the definitive limiting factor when moving from Low to Medium and above, making it the component that dictates the settings ceiling for this system.

Resolution Scaling

The FPS drops from 1080p to 4K are steep and reveal the nature of the bottleneck. At Low settings, scaling from 1920x1080 to 2560x1440 results in a drop from 176 FPS to 112 FPS, a 64 FPS decrease. Moving from 1440p to 3840x2160 at Low drops the average from 112 FPS to 59 FPS, a further 53 FPS decrease. This shows a clear, predictable decline as pixel count increases.

The scaling pattern changes at higher settings. At Medium, the FPS goes from 124 (1080p) to 79 (1440p) to 42 (4K). At High, it goes from 96 to 61 to 32. At Ultra, it falls from 64 to 40 to 21. The relative drops are consistent, but the absolute FPS values at 4K are all below 60, indicating that the GPU is completely saturated at that resolution regardless of the settings. The data suggests that the resolution scaling is almost purely GPU-bound. The CPU, with its 16 cores and 32 threads, is not showing signs of being a bottleneck in these measurements, as the FPS scales down as the pixel workload increases, which is the classic sign of a GPU-limited scenario.

For this specific combination, the sweet spot is clearly 1080p. The jump from 1080p to 1440p costs a significant amount of FPS (64 FPS at Low), but the visual improvement may be worth it for some. However, 4K is not feasible for a smooth experience, as even the lowest settings cannot maintain a 60 FPS average. The data indicates that users should target 1080p for maximum performance or 1440p for a balanced experience, but they should avoid 4K unless they are willing to accept sub-60 FPS averages on Low settings.

Measured FPS Breakdown

The measured FPS data provides a complete picture of this hardware's capabilities in Fortnite. Here is the exact breakdown for all tested configurations.

1920x1080 (1080p)

• Low: 176 FPS average
• Medium: 124 FPS average, with a minimum of 106 FPS and a maximum of 143 FPS
• High: 96 FPS average
• Ultra: 64 FPS average

2560x1440 (1440p)

• Low: 112 FPS average
• Medium: 79 FPS average, with a minimum of 67 FPS and a maximum of 91 FPS
• High: 61 FPS average
• Ultra: 40 FPS average

3840x2160 (4K)

• Low: 59 FPS average
• Medium: 42 FPS average, with a minimum of 35 FPS and a maximum of 48 FPS
• High: 32 FPS average
• Ultra: 21 FPS average

The 1080p results show that the Low preset is the only one that pushes the average above 150 FPS, which is ideal for high-refresh-rate monitors. The Medium preset's minimum of 106 FPS is still above the 100 FPS mark, but the average is significantly lower. At 1440p, the Medium preset's minimum is 67 FPS, which is close to the 60 FPS threshold, while the Low preset maintains a comfortable 112 FPS average. The 4K results are uniformly poor, with even the best case (Low) hitting a 59 FPS average, and the Ultra preset falling to a 21 FPS average, which is a slideshow for a game like this. These numbers confirm that this CPU/GPU combo is best suited for 1080p and 1440p gaming, with a strong preference for the Low preset to unlock the full potential of the hardware.

Q: Is the CPU or GPU the bottleneck in this system?

A: The benchmark results indicate the GPU is the primary bottleneck. The FPS scales down significantly as the resolution increases (e.g., from 176 FPS at 1080p Low to 59 FPS at 4K Low), which is a classic sign of a GPU-limited workload. The Ryzen 9 5950X, with its high multi-threaded performance, is not the limiting factor.

Q: How does the Intel Arc B570 compare to its direct rivals?

A: The B570 has an average benchmark score of 20556 and is in the 65th percentile. Its nearest rival is the NVIDIA GeForce RTX 3070 Mobile, which has a 0.1% higher average score, and the Intel Arc A750, which has a -0.1% lower score. This puts it in a performance class very close to those two cards.

Q: Is the 1080p Medium preset viable for this build?

A: Yes, it is viable. The Medium preset at 1080p produces an average of 124 FPS, with a minimum of 106 FPS. This is still a very high frame rate and will be smooth on most high-refresh-rate monitors, though it is 52 FPS lower than the Low preset.

Q: What is the most stable setting for a consistent frame rate?

A: The data shows that the Medium preset provides the most information on stability with minimum and maximum FPS values. At 1080p, the minimum is 106 FPS and the maximum is 143 FPS, a range of 37 FPS. This is a wider range, but the minimum is still high. The Low preset averages are high, but without min/max data, the Medium preset's measured range suggests it maintains a relatively stable experience.

CPU Role

The AMD Ryzen 9 5950X is a high-end desktop processor with 16 cores and 32 threads, based on the Zen 3 architecture (Vermeer). It has a base clock of 3.40 GHz and a boost clock of 4.90 GHz, and it supports DDR4 memory with a dual-channel bus. Its benchmark scores are impressive, with a Cinebench R23 multi-core score of 26017 and a single-core score of 1614. It sits in the 91st percentile of all CPUs, with an average benchmark score of 51947.

In this Fortnite test, the CPU's role is to feed the GPU with enough data. The benchmark data shows that the CPU is not the limiting factor. The FPS is clearly dictated by the GPU's performance, as evidenced by the significant FPS drops when increasing resolution or settings. For example, the 5950X's nearest rival, the Intel Core i9-13900F, has a 0.4% higher average score, and the Intel Core Ultra 5 235HX is only 0.2% higher. This level of CPU performance is more than sufficient for Fortnite, which is a game that typically relies more on GPU performance at these settings.

The 5950X's high core count and strong single-threaded performance (Passmark single-thread score of 3470) ensure that it can handle the game's logic and physics without causing frame drops. The data suggests that the CPU has plenty of headroom, as the FPS scales down in a pattern that is entirely consistent with a GPU bottleneck. While a weaker CPU might cause stutters or FPS dips in CPU-intensive scenarios, this chip's robust specifications, including 64 MB of L3 cache, make it a stable foundation for this GPU. In this pairing, the Ryzen 9 5950X is a capable partner that ensures the Arc B570 is the component that defines the system's gaming performance.
