How This Combo Ranks

The comboRankInGame of 1283 out of 1667 combos places this system firmly in the lower half of tested configurations for Don't Starve Together. This is a notable underperformance relative to what the individual component benchmarks would suggest, as the Arc B580's average benchmark score of 23021 places it competitively against the NVIDIA GeForce RTX 4060, which sits just 0.7% higher in average score. Similarly, the Core i5-9400's average benchmark score of 2305 puts it within 0.6% of the Intel Core i7-8809G in the nearestRivals list. However, the game's measured FPS data reveals that this combination struggles to translate raw component strength into top-tier frame rates, particularly at higher resolutions and settings where the GPU becomes the limiting factor.

The ranking gap becomes more understandable when examining the measured FPS across the board. At 1080p Low, the system delivers 187.5 FPS, which is strong, but at 4K Ultra, it drops to 34.1 FPS—a figure that falls below the 45.1 FPS achieved at 4K High. This indicates that the combo's performance ceiling is constrained by the GPU's ability to handle the game's graphical load at higher presets, while the CPU's modest 6-core, 6-thread configuration may not provide enough headroom to push frame rates higher in less demanding scenarios. The data shows a system that is competent but not exceptional, with the ranking reflecting a balance where neither component fully dominates the other's limitations.

A: The FPS drops from 187.5 at 1080p Low to 77.4 at 4K Low, and from 45.1 at 4K High to 88.4 at 1080p High. This scaling pattern shows that the GPU's 12 GB of GDDR6 memory and 456.0 GB/s bandwidth are sufficient for 4K, but the performance hit is substantial, particularly at higher presets.

Q: How does the CPU's single-core performance affect the game?

A: The i5-9400 has a boost clock of 4.10 GHz and a Cinebench R23 single-core score of 1125. Given that Don't Starve Together relies on single-threaded performance, this clock speed is adequate for maintaining playable frame rates, but the 6-thread limit may cap performance in scenarios with many entities on screen.

GPU Role

The Intel Arc B580 brings 12 GB of GDDR6 memory on a 192-bit bus, delivering 456.0 GB/s of bandwidth—a configuration that proves sufficient for this game's needs across all tested resolutions. The GPU's base and boost clocks are both 2670 MHz, which is a modest clock speed for a modern card, yet the 2560 shading units and 80 ROPs provide the raw throughput necessary to handle the game's 2D-art-driven rendering. The memory clock runs at 2375 MHz, translating to 19 Gbps effective, which helps maintain consistent frame delivery even at 4K where the game's asset streaming demands more bandwidth.

The benchmark results show that the GPU's performance in this title is largely determined by the preset rather than the resolution, with the gap between Low and Ultra settings being more pronounced at higher resolutions. At 1080p, the difference between Low (187.5 FPS) and Ultra (88.4 FPS) is 99.1 FPS, while at 4K, the same gap is 43.3 FPS (77.4 vs 34.1). This indicates that the GPU's compute resources are the primary driver of performance at lower resolutions, but at 4K, memory bandwidth and pixel throughput become more critical, as evidenced by the 213.6 GPixel/s pixel rate and 427.2 GTexel/s texture rate. The card's 13.67 TFLOPS FP32 performance is adequate for this game, but the data shows that the Ultra preset at 4K pushes the GPU to its limits, resulting in sub-60 FPS performance.

Measured FPS Breakdown

The measured FPS data provides a comprehensive view of the combo's performance across three resolutions and four settings levels. At 1920x1080, the system delivers 187.5 FPS on Low, 128.1 FPS on Medium, 108.6 FPS on High, and 88.4 FPS on Ultra. These numbers show a clear scaling pattern where each step up in settings costs roughly 20-30% performance, with the largest drop occurring from Low to Medium (59.4 FPS decrease). The 1080p results are all above 60 FPS, making this resolution viable for high-refresh-rate monitors even at the highest preset.

Moving to 2560x1440, the performance drops predictably but remains playable: 130.3 FPS on Low, 89.8 FPS on Medium, 76.9 FPS on High, and 61.9 FPS on Ultra. The 1440p Ultra result is notably close to the 60 FPS threshold, suggesting that this combo can handle 1440p gaming with minor tweaks. At 3840x2160, the results become more varied: 77.4 FPS on Low, 55.1 FPS on Medium, 45.1 FPS on High, and 34.1 FPS on Ultra. The 4K High and Ultra results fall below 60 FPS, indicating that this resolution is only suitable for lower presets with this hardware combination.

Resolution Scaling

The FPS scaling from 1080p to 4K reveals a consistent pattern of performance degradation that points to the GPU as the primary limiting component. At Low settings, the frame rate drops from 187.5 FPS at 1080p to 130.3 FPS at 1440p (a 30.5% decrease) and then to 77.4 FPS at 4K (a 40.6% decrease from 1440p). This scaling is steeper than the resolution's pixel count increase would suggest, indicating that the GPU's processing power, not just memory bandwidth, is the constraint. The 2670 MHz clock speed and 13.67 TFLOPS FP32 performance are the relevant metrics here, as they determine how quickly the GPU can process the increased pixel count.

At Ultra settings, the scaling is even more dramatic: 88.4 FPS at 1080p, 61.9 FPS at 1440p (a 30.0% decrease), and 34.1 FPS at 4K (a 44.9% decrease from 1440p). The steeper drop at Ultra settings suggests that the GPU's 80 ROPs and 213.6 GPixel/s pixel rate become saturated more quickly when rendering higher-quality effects, which is typical for a game with this art style. The data shows that the CPU's 6-core, 6-thread configuration is not the bottleneck at higher resolutions, as the FPS drops are consistent with GPU-bound scaling rather than CPU limitations.

Settings Recommendations

Based on the measured FPS data, the optimal settings for this combo depend on the target resolution and desired frame rate. At 1920x1080, all presets deliver above 60 FPS, with Ultra achieving 88.4 FPS, making the highest settings viable for smooth gameplay. For players prioritizing frame rate over visual fidelity, Low settings at 1080p provide 187.5 FPS, which is ideal for competitive play or high-refresh-rate displays.

At 2560x1440, the recommended setting is High, which delivers 76.9 FPS—a comfortable margin above 60 FPS while maintaining good visual quality. Dropping to Medium yields 89.8 FPS, which may be preferable for those seeking smoother motion, but High offers the best balance of visual fidelity and performance. Ultra at 1440p hits 61.9 FPS, which is borderline playable but may experience noticeable frame drops in busy scenes. At 3840x2160, Low settings at 77.4 FPS is the only preset that maintains a solid 60+ FPS experience, with Medium at 55.1 FPS being acceptable for less demanding players. High and Ultra at 4K are not recommended due to sub-45 FPS performance.

CPU Role

The Intel Core i5-9400 provides 6 cores and 6 threads, with a base clock of 2.90 GHz and a boost clock of 4.10 GHz, drawing 65 W TDP. This Coffee Lake architecture CPU has 9 MB of shared L3 cache and supports dual-channel DDR4 memory at 42.7 GB/s bandwidth. The Cinebench R23 scores of 7969 multicore and 1125 single-core place this CPU in the 50th percentile of all processors, with nearest rivals including the Intel Core i3-10305 (0.2% higher average score) and the Intel Core i7-8809G (0.6% lower average score).

In Don't Starve Together, the CPU's role is less prominent than the GPU's, as evidenced by the FPS scaling patterns. At 1080p Low, the 187.5 FPS result suggests the CPU can feed the GPU adequately at lower resolutions, but the drop to 88.4 FPS at Ultra indicates that the GPU becomes the limiting factor. The CPU's 6-thread limit may constrain performance in scenarios with many entities or complex simulations, but the data does not show a clear CPU bottleneck. The boost clock of 4.10 GHz provides sufficient single-threaded performance for this game's logic, while the 65 W TDP keeps power consumption low. The CPU's PCIe Gen 3, 16 Lanes connection to the Arc B580 is adequate for this workload, as the GPU's PCIe 4.0 x8 interface is backward compatible, and the game's data transfer requirements are modest.
