Don't Starve Together

The Intel Core i5-10400F paired with the NVIDIA GeForce RTX 5090 presents an extreme generational and performance-class mismatch in Don't Starve Together. The benchmark data shows a system where the GPU is overwhelmingly dominant, yet the final frame rates are heavily mediated by the CPU's capabilities and the game's engine limitations. This analysis breaks down the measured performance, component roles, and what the numbers mean for a builder considering this combination.

FAQ

GPU Role

The NVIDIA GeForce RTX 5090 is an absolute powerhouse, built on the Blackwell 2.0 architecture with 21,760 shading units and 176 ROPs. Its boost clock reaches 2407 MHz, and it delivers 104.8 TFLOPS of FP32 compute performance. The 32 GB of GDDR7 memory with a 1.79 TB/s bandwidth is overkill for Don't Starve Together, a game with a stylized, low-poly art style that does not stress memory capacity or bandwidth.

The measured FPS data confirms the GPU is not the limiting factor in this pairing. At 1080p Low settings, the system achieves 208 FPS, but at 1080p Ultra, it drops to 156.1 FPS. This 25% performance penalty for higher settings is relatively modest, suggesting the GPU has ample headroom. At 4K Ultra, the average is 86.4 FPS, which is a 58% drop from the 1080p Low figure. Even at 4K Ultra, the RTX 5090 is not being pushed to its limits; the game's rendering load is simply not heavy enough.

The GPU's benchmark percentile of 94% of all GPUs, with an average benchmark score of 84306, places it near the very top of the performance hierarchy. However, in this specific game, the delta between the RTX 5090 and its nearest rivals (all within 1.6% in average score) does not translate into meaningful FPS differences because the game is not GPU-bound at most settings and resolutions tested. The data indicates the GPU's role here is to provide a high ceiling that the CPU and game engine cannot fully utilize.

CPU Role

The Intel Core i5-10400F is a 6-core, 12-thread processor from the Comet Lake generation, running at a base clock of 2.90 GHz and boosting to 4.30 GHz. It uses 14 nm process technology and supports DDR4 memory with a dual-channel interface. Its 12 MB of shared L3 cache and 42.7 GB/s memory bandwidth are modest figures that reflect its 2020-era design.

In Don't Starve Together, a game that relies heavily on simulation and logic updates for its world, CPU performance is often the primary constraint. The i5-10400F's single-threaded score of 1453 in Cinebench R23 and 688 in 3DMark single-thread test indicates it has decent per-core performance, but it is not exceptional by modern standards. Its multi-threaded score of 10297 in Cinebench R23 shows it can handle parallel workloads, but the game's engine may not fully utilize all 12 threads.

The CPU's percentile of 73% against all CPUs, with an average benchmark score of 14168, places it in the upper-mid range. Its nearest rivals, including the AMD EPYC 7552 (0.4% ahead) and the Intel Core i5-8500 (1.1% behind), show that it sits in a competitive but not dominant position. The data suggests that in this pairing, the i5-10400F is the bottleneck, particularly at lower resolutions and settings where the GPU can easily render frames faster than the CPU can process game logic.

How This Combo Ranks

With a combo rank of 351 out of 1667 tested configurations, this pairing sits in the 79th percentile of all combinations tested for Don't Starve Together. This is a strong showing, but it is not commensurate with the RTX 5090's individual GPU percentile of 94%. The gap between the GPU's ranking and the combo's ranking highlights the CPU's limiting effect.

The combo rank of 351 means that 1,316 other combinations performed better in this game. Given that the RTX 5090 is among the fastest GPUs available, the ranking suggests that many of those better-performing combos likely feature more capable CPUs. The i5-10400F's 73rd percentile CPU ranking is significantly lower than the GPU's 94th percentile, indicating a clear imbalance in this pairing.

The data shows that while the combo is firmly in the top quarter of all tested systems, it leaves substantial performance on the table. A more balanced pairing, where the CPU's performance class more closely matches the GPU's, would likely achieve a much higher rank. The 351st rank is respectable, but it underperforms what the GPU alone suggests is possible.

Resolution Scaling

The measured FPS data reveals clear resolution scaling patterns. Moving from 1080p to 1440p to 4K at the same settings shows consistent FPS drops, but the magnitude varies by settings preset.

At Low settings, the average FPS drops from 208 at 1080p to 182.1 at 1440p (a 12.5% decrease) and then to 155.1 at 4K (a 14.8% further decrease). At Ultra settings, the drop is steeper: from 156.1 at 1080p to 138.8 at 1440p (an 11.1% decrease) and then to 86.4 at 4K (a 37.8% further decrease).

The pattern indicates that at Low settings, the system is heavily CPU-bound at all resolutions. The FPS difference between 1080p and 4K is only 52.9 FPS (from 208 to 155.1), which is a relatively small drop for a 4x increase in pixel count. This suggests the CPU is the primary constraint, and the GPU has spare capacity even at 4K.

At Ultra settings, the 4K performance drop is much more pronounced, indicating that the GPU becomes more of a factor at the highest quality preset and resolution. The 86.4 FPS at 4K Ultra is still very playable, but the 37.8% drop from 1440p Ultra suggests the GPU is now doing meaningful work. Overall, the resolution scaling data supports the conclusion that the CPU is the limiting component at lower settings, while the GPU becomes co-limiting at 4K Ultra.

Measured FPS Breakdown

The full set of measured FPS data provides a comprehensive picture of performance across resolutions and settings.

At 1920x1080, the system delivers its highest frame rates. Low settings produce an average of 208 FPS, Medium settings 182.3 FPS, High settings 172.7 FPS, and Ultra settings 156.1 FPS. The spread from Low to Ultra is 51.9 FPS, showing that settings have a meaningful but not dominant impact at this resolution.

At 2560x1440, performance remains strong. Low settings average 182.1 FPS, Medium 161 FPS, High 154.1 FPS, and Ultra 138.8 FPS. The drop from 1080p to 1440p is relatively small, ranging from 12.5% at Low to 11.1% at Ultra, indicating the system remains CPU-bound.

At 3840x2160, the impact of resolution becomes more apparent. Low settings average 155.1 FPS, Medium 130.5 FPS, High 109.3 FPS, and Ultra 86.4 FPS. The drop from 1440p to 4K is significant, especially at Ultra settings where the FPS falls by 37.8%. Even at 4K Ultra, the 86.4 FPS average is playable, but it is a far cry from the 208 FPS ceiling at 1080p Low.

The data shows that this combo can comfortably handle Don't Starve Together at any resolution and settings combination tested, with the minimum average FPS being 86.4 at 4K Ultra. However, the performance scaling reveals that the CPU's limitations prevent the RTX 5090 from delivering its full potential, particularly at lower resolutions and settings. For builders seeking maximum frame rates in this game, a more powerful CPU would be necessary to fully utilize the RTX 5090's capabilities.
