Don't Starve Together

The Intel Core i5-9400 paired with the NVIDIA GeForce RTX 3070 delivers a highly capable Don't Starve Together experience, with the data showing a clear progression from playable 4K Ultra to exceptionally high refresh-rate 1080p performance. The benchmark results indicate that the RTX 3070 is the dominant component at higher resolutions, while the i5-9400 becomes a more significant factor as resolution drops. This combination ranks in the 53rd percentile of tested combos, placing it in the upper half of all configurations measured for this game.

Resolution Scaling

The FPS data reveals a predictable and steep decline as resolution increases, but the magnitude of that drop tells a clear story about system balance. Moving from 1920x1080 to 2560x1440 at High settings, the average framerate falls from 150.1 FPS to 108 FPS, a reduction of 28%. The jump from 1440p to 4K at High settings is even more severe, with the average dropping from 108 FPS to 62.1 FPS, a further 42.5% decline. This pattern strongly indicates that the GPU is the limiting factor at higher resolutions, as the pixel-pushing workload scales almost linearly with the resolution increase.

At Low settings, the scaling is even more revealing of the CPU's role. The 1080p Low result of 198.5 FPS drops to 175.1 FPS at 1440p Low, a modest 11.8% decline. However, the jump to 4K Low shows a much larger drop to 110 FPS, a 37.2% reduction from the 1440p figure. This non-linear scaling at Low settings suggests that the CPU is capable of feeding the GPU at 1080p and 1440p, but the sheer pixel count at 4K finally overwhelms the GPU's fill rate, even with minimal graphical load.

The gap between Low and Ultra settings widens dramatically at higher resolutions. At 1080p, the difference between Low (198.5 FPS) and Ultra (119.3 FPS) is 79.2 FPS. At 4K, that same Low-to-Ultra gap is 58.8 FPS (110 vs 51.2). This compression of the settings range at 4K indicates that the GPU is being saturated regardless of quality preset, whereas at 1080p, the higher settings introduce enough shading and texture work to engage the GPU more fully, creating a larger performance spread.

At 1080p Low, the 198.5 FPS result indicates the CPU can sustain very high framerates, but the diminishing returns from 1080p to 1440p at Low settings (198.5 to 175.1 FPS) hint that CPU limitations begin to appear at very high framerates.

Q: What is the expected performance difference between High and Ultra settings?

A: At 1080p, High settings deliver 150.1 FPS while Ultra delivers 119.3 FPS, a 20.5% reduction. At 1440p, the drop is from 108 FPS to 82.4 FPS, a 23.7% reduction. At 4K, the gap narrows, with High at 62.1 FPS and Ultra at 51.2 FPS, a 17.6% reduction. The smaller relative gap at 4K suggests that the GPU is already near its limits.

Q: How does this combo rank among all tested configurations?

A: This specific combination of the Intel Core i5-9400 and NVIDIA GeForce RTX 3070 ranks 777th out of 1667 tested combos. This places it in the upper half of all configurations, indicating a solid, mid-to-high-tier pairing for this game.

Q: Can this system handle 4K gaming?

A: Yes, but with caveats. At 4K High settings, the average framerate is 62.1 FPS, which is playable. At 4K Medium, it improves to 74.9 FPS. However, 4K Ultra drops to 51.2 FPS, which may be below the preference of some players seeking a locked 60 FPS experience.

GPU Role

The NVIDIA GeForce RTX 3070 is the clear performance driver in this pairing, particularly at higher resolutions. Its 8 GB of GDDR6 memory on a 256-bit bus provides 448.0 GB/s of bandwidth, which is sufficient for the texture-heavy environments of Don't Starve Together at 4K. The GPU's 5888 shading units and 96 ROPs deliver a pixel rate of 165.6 GPixel/s, a figure that explains the steep drop from 1080p to 4K — the ROP throughput becomes a limiting factor when pixel count quadruples.

The clock behavior of the RTX 3070 is also relevant. With a base clock of 1500 MHz and a boost clock of 1725 MHz, the card operates within a narrow frequency range. The 14 Gbps effective memory clock, combined with the 256-bit bus, ensures that texture streaming keeps pace with the shading units. In the benchmark data, this manifests as a smooth scaling from Low to Ultra at 1440p, where the GPU has enough headroom to handle increased settings without catastrophic framerate drops.

The GPU's 8 GB VRAM capacity is a key asset at 4K. The data shows that 4K Medium delivers 74.9 FPS, which is only slightly below the 108 FPS achieved at 1440p High. This suggests that the GPU is not running out of memory at 4K Medium, allowing the core processor to remain the primary bottleneck. However, the Ultra preset at 4K drops to 51.2 FPS, indicating that the increased shading and post-processing loads are taxing the GPU's compute resources rather than its memory subsystem.

How This Combo Ranks

The combination of the Intel Core i5-9400 and NVIDIA GeForce RTX 3070 achieves a rank of 777 out of 1667 tested combos in Don't Starve Together. This places it in the 53.4th percentile, meaning it outperforms slightly more than half of all tested configurations. This is a respectable position, but it does not place it in the elite tier.

The ranking reflects a balance between the CPU and GPU. The i5-9400, with a 50th percentile ranking among all CPUs, is a mid-range processor. The RTX 3070, with a 72nd percentile ranking among all GPUs, is a high-end graphics card. The combination of these two components produces a system that is stronger than the sum of its parts in this game, as the CPU's six cores and six threads provide adequate feeding for the GPU without becoming a severe bottleneck.

Within the context of the 1667 combos, this rank suggests that many configurations with newer CPUs or higher-end GPUs will outperform it. However, the measured FPS data shows that this combo still delivers excellent playable framerates at all tested resolutions and settings, with the only sub-60 FPS result being 4K Ultra at 51.2 FPS. The rank of 777 is thus a signal of the balanced nature of this pairing rather than an indication of poor performance.

CPU Role

The Intel Core i5-9400 serves as a capable foundation for the RTX 3070, but its role becomes more apparent at lower resolutions. With 6 cores and 6 threads, a base clock of 2.90 GHz, and a boost clock of 4.10 GHz, this Coffee Lake processor provides solid single-threaded performance, as evidenced by its Cinebench R23 single-core score of 1125. This is critical for Don't Starve Together, which relies heavily on game logic and entity updates that are often single-threaded.

The CPU's 9 MB of shared L3 cache and 64 KB L1 cache per core help maintain low latency for game data. In the measured FPS, the CPU's influence is most visible at 1080p Low, where the average hits 198.5 FPS. This high framerate suggests the CPU can keep up with the GPU's output at lower graphical loads. However, the gap between 1080p Low (198.5 FPS) and 1440p Low (175.1 FPS) is only 13.4%, which is smaller than the pixel count increase (from 2.07 million to 3.69 million pixels), indicating that CPU limitations begin to cap performance at very high framerates.

The i5-9400's multi-core performance is modest, with a Cinebench R20 multi-core score of 3346 and an R23 score of 7969. In a game like Don't Starve Together, which may not scale perfectly across all six threads, this means the CPU can occasionally become a limiting factor in busy scenes with many entities. The benchmark data at 1080p Ultra (119.3 FPS) versus 1080p High (150.1 FPS) shows a 20.5% drop, which could be attributed to increased draw calls that stress the CPU's six threads.

Measured FPS Breakdown

At 1920x1080, the lowest resolution tested, the system delivers exceptional performance across all settings. The Low preset averages 198.5 FPS, Medium averages 176 FPS, High averages 150.1 FPS, and Ultra averages 119.3 FPS. All four presets are well above the 60 FPS threshold, making 1080p a resolution where this combo excels regardless of quality preference. The gap between Low and Ultra is 79.2 FPS, showing that the GPU has ample headroom even at the highest settings.

Moving to 2560x1440, the performance remains very strong but begins to show the GPU's workload. The Low preset averages 175.1 FPS, which is only 11.8% less than the 1080p Low result. Medium averages 123.5 FPS, High averages 108 FPS, and Ultra averages 82.4 FPS. The gap between Low and Ultra at 1440p is 92.7 FPS, indicating that the higher settings are engaging the GPU more heavily. The 82.4 FPS at Ultra is still comfortably above 60 FPS, making 1440p Ultra a viable option.

At 3840x2160, the GPU is clearly the primary bottleneck. The Low preset averages 110 FPS, which is a significant 37.2% drop from 1440p Low. Medium averages 74.9 FPS, High averages 62.1 FPS, and Ultra drops to 51.2 FPS. The jump from Low to Medium at 4K is a 31.9% reduction, while the jump from High to Ultra is a 17.6% reduction. The 4K Ultra result is the only measured configuration that falls below 60 FPS, suggesting that players targeting 4K should stick to High settings for a locked 60 FPS experience.

Settings Recommendations

For players prioritizing high refresh rates at 1080p, the Ultra preset at 119.3 FPS is the optimal choice. This provides the best visual fidelity while still maintaining framerates well above 100 FPS. The Medium preset at 176 FPS is unnecessary for most displays, as it sacrifices visual quality for framerates that exceed the refresh rate of most monitors.

At 1440p, the High preset offers the best balance, delivering 108 FPS average. This is ideal for 144Hz displays, providing enough headroom to avoid dips below the refresh rate in demanding scenes. The Ultra preset at 82.4 FPS is also a strong option for players with 60Hz or 75Hz displays, as it maintains a comfortable margin above 60 FPS.

For 4K gaming, the High preset at 62.1 FPS is the recommended choice. This delivers smooth gameplay on standard 60Hz displays while retaining most of the visual enhancements. The Medium preset at 74.9 FPS is a viable alternative for players who prefer higher framerate headroom, but the visual downgrade from High is noticeable. The Ultra preset at 51.2 FPS should be avoided, as it falls below the 60 FPS threshold and may result in a less fluid experience. Overall, the data suggests that this combo is best suited for 1440p High settings, where it achieves a perfect balance of visual quality and performance.
