Rust

Rust presents a uniquely demanding workload that stresses both the CPU and GPU in ways few other titles can match. The benchmark data for the Intel Core Ultra 9 290K Plus and NVIDIA GeForce RTX 5090 D combination reveals a system that is overwhelmingly powerful, yet the frame pacing and scaling characteristics show that even this flagship pairing has to contend with the game's heavy simulation and rendering demands. The measured results across three resolutions and four quality presets provide a clear picture of where the bottleneck lies and how the hardware responds to different settings.

Resolution Scaling

The frame rate scaling from 1080p to 4K is the most telling indicator of system balance in Rust. At 1920x1080 with Low settings, the combo achieves 283 FPS average. Moving to 2560x1440 Low drops that to 239 FPS, a reduction of approximately 15.5%. At 3840x2160 Low, the average falls to 141 FPS, which represents a further 41% drop from the 1440p result. This scaling pattern is steep, but it is also expected for a game like Rust where the CPU is heavily involved in the simulation of the world, entities, and physics.

The picture changes when looking at the High preset. At 1080p High, the average is 197 FPS. At 1440p High, it drops to 136 FPS, a 31% reduction. At 4K High, the average is 80 FPS, a 41% drop from 1440p. The scaling from 1440p to 4K is consistent across Low and High, suggesting that at 4K, the GPU is becoming the primary limiting factor. The RTX 5090 D is a massive GPU with 32 GB of GDDR7 memory and a 512-bit bus, but 4K rendering in Rust with its draw distances and object counts still presents a significant pixel throughput challenge.

The most interesting data point is the Medium preset, which includes min and max FPS values that the other presets lack. At 1080p Medium, the average is 233 FPS with a min of 198 and a max of 268. At 1440p Medium, the average drops to 161 FPS with a min of 136 and a max of 185. At 4K Medium, the average is 95 FPS with a min of 81 and a max of 109. The spread between min and max FPS is tight, roughly 30 FPS in each case, which indicates a stable frame pacing situation. This consistency suggests that the combination of the 24-core CPU and the RTX 5090 D is well-matched for maintaining a steady frame delivery when the settings are not maxed out.

The Ultra preset shows the heaviest load. At 1080p Ultra, the average is 150 FPS. At 1440p Ultra, it drops to 103 FPS. At 4K Ultra, the average is just 61 FPS. The drop from 1440p to 4K at Ultra is 40.8%, which is the steepest percentage drop of any preset. This indicates that at Ultra settings, the GPU is being pushed to its absolute limit, and the 4K resolution combined with maximum quality settings overwhelms even the 104.8 TFLOPS of FP32 compute power available in the RTX 5090 D. The data suggests that the limiting component shifts depending on the resolution and preset; at lower resolutions and presets, the CPU is the constraint, while at 4K Ultra, the GPU is clearly the bottleneck.

How This Combo Ranks

The combination of the Intel Core Ultra 9 290K Plus and the NVIDIA GeForce RTX 5090 D ranks 3rd out of 2953 tested combinations for Rust. This places the combo in the 99.9th percentile of all systems tested, meaning it outperforms the vast majority of configurations. The two systems ranked above it are not named in the data, but achieving a top-3 position out of nearly three thousand combinations confirms the raw power of this pairing.

The CPU itself holds a 96th percentile ranking against all CPUs, and the GPU holds a 92nd percentile ranking against all GPUs. However, the combo rank of 3rd is significantly higher than either individual component percentile, which suggests that the pairing is particularly synergistic for Rust. The game appears to benefit from the specific combination of the CPU's cache layout and the GPU's massive memory bandwidth, resulting in a system that punches above its already elite individual component scores.

The GPU's nearest rivals in the benchmark database include the AMD Radeon RX 6650M XT and the RX 6850M XT, which are mobile GPUs, as well as NVIDIA Tesla P100 parts. The RTX 5090 D has a 1.1% higher average benchmark score than the RX 6650M XT and is 1.6% lower than the RX 6850M XT. This is a peculiar data point, as those are laptop-class GPUs, but it reflects the specific metrics used in the aggregate benchmark score rather than gaming performance. In actual Rust gameplay, the 5090 D's 32 GB of VRAM and 1.79 TB/s of bandwidth provide a substantial advantage that these aggregate scores do not fully capture.

Measured FPS Breakdown

The measured FPS data provides a comprehensive view of the system's capabilities across the entire settings spectrum.

At 1920x1080, the Low preset delivers an average of 283 FPS. This is the highest measured frame rate in the entire dataset. The Medium preset at 1080p delivers 233 FPS average, with a minimum of 198 and a maximum of 268. The High preset at 1080p drops to 197 FPS average. The Ultra preset at 1080p delivers 150 FPS average. The progression from Low to Ultra at 1080p shows a 47% reduction in average frame rate, from 283 down to 150 FPS.

Moving to 2560x1440, the Low preset delivers 239 FPS average. The Medium preset at 1440p delivers 161 FPS average, with a minimum of 136 and a maximum of 185. The High preset at 1440p delivers 136 FPS average. The Ultra preset at 1440p delivers 103 FPS average. The drop from Low to Ultra at 1440p is 56.9%, showing that the higher resolution amplifies the performance cost of higher settings.

At 3840x2160, the Low preset delivers 141 FPS average. The Medium preset at 4K delivers 95 FPS average, with a minimum of 81 and a maximum of 109. The High preset at 4K delivers 80 FPS average. The Ultra preset at 4K delivers 61 FPS average. The drop from Low to Ultra at 4K is 56.7%, consistent with the percentage drop seen at 1440p.

The data shows a clear pattern: the gap between Low and Ultra settings widens as resolution increases. At 1080p, there is a 133 FPS difference between Low and Ultra. At 1440p, that gap is 136 FPS. At 4K, the gap is 80 FPS. While the absolute gap remains similar between 1080p and 1440p, the 4K gap is smaller in absolute terms because the whole performance envelope shifts downward.

CPU Role

The Intel Core Ultra 9 290K Plus is a 24-core, 24-thread processor based on the Arrow Lake Refresh architecture. It has a base clock of 3.70 GHz and a boost clock of 5.80 GHz. The processor is built on a 3 nm process node from TSMC and contains 17,800 million transistors on a 243 mm² die. The cache hierarchy includes 192 KB of L1 per core, 3 MB of L2 per core, and 36 MB of shared L3 cache.

In Rust, the CPU's role is critical because the game runs a complex simulation that includes player positions, building integrity, resource gathering, and environmental events. The 24 cores provide substantial parallel processing capability, but Rust historically has a single-threaded simulation core that can become a bottleneck. The high boost clock of 5.80 GHz helps mitigate this, and the benchmark results support this interpretation.

The CPU's benchmark scores are impressive. In Cinebench R23, it scores 51,731 in multi-core and 7,303 in single-core. The Passmark single-thread score is 4,823, and the multi-thread score is 60,860. The CPU holds a 96th percentile ranking against all CPUs, with an average benchmark score of 84,003. Its nearest rival is the Intel Core Ultra 9 285K, which has an average score of 83,807, a delta of 0.2%. The AMD EPYC 4584PX is 1.1% slower, and the EPYC 9135 is 1.2% slower. The AMD EPYC 7F72 is 1.3% faster.

The data suggests that the CPU is capable of driving very high frame rates in Rust when the resolution is low enough to remove the GPU as a constraint. The 283 FPS at 1080p Low is likely near the ceiling of what the game's engine can produce with this processor. The fact that the 1080p Low result is 283 FPS and the 1080p Medium result is 233 FPS indicates that the CPU can sustain high frame delivery even with additional rendering work, but the gap between Low and Medium (50 FPS) shows that even at 1080p, the GPU is starting to contribute to the frame time.

Settings Recommendations

The measured data allows for clear settings recommendations based on the target resolution and desired frame rate.

For 1080p gaming, the High preset at 197 FPS average is an excellent choice for high-refresh-rate monitors. The Ultra preset at 150 FPS also provides a smooth experience and is only 24% slower than High. The Low preset at 283 FPS is overkill for most displays and sacrifices visual quality unnecessarily. The Medium preset at 233 FPS is a balanced choice, but the High preset offers better visuals with only a 15% performance penalty.

For 1440p gaming, the High preset at 136 FPS is the sweet spot for 144Hz monitors. The Medium preset at 161 FPS provides a higher frame rate with a 15% reduction in quality. The Ultra preset at 103 FPS is still playable and offers the best visuals, but the 103 FPS average is below the refresh rate of many high-end 1440p monitors. The Low preset at 239 FPS is not recommended because it leaves too much visual quality on the table for a frame rate that exceeds most displays' capabilities.

For 4K gaming, the Medium preset at 95 FPS is the best experience for smooth gameplay. The High preset at 80 FPS is also playable and provides better visual fidelity. The Ultra preset at 61 FPS is borderline for a game like Rust where quick reactions matter in PvP situations. The Low preset at 141 FPS is the only 4K option that consistently stays above 100 FPS, but the visual downgrade is significant. The data indicates that 4K Medium or High is the optimal trade-off for this combo.

The Medium preset stands out in the data because it is the only one with min/max FPS measurements. The tight frame windows at all three resolutions (30 FPS spread at 1080p, 49 FPS at 1440p, and 28 FPS at 4K) suggest that Medium offers the most consistent frame pacing. This makes it the recommended preset for competitive play where frame time consistency is more important than average FPS.

GPU Role

The NVIDIA GeForce RTX 5090 D is a massive GPU based on the Blackwell 2.0 architecture. It uses the GB202 chip, which is manufactured on a 5 nm process from TSMC and contains 92,200 million transistors on a 750 mm² die. The GPU has a base clock of 2017 MHz and a boost clock of 2407 MHz. The memory subsystem is equally impressive: 32 GB of GDDR7 memory on a 512-bit bus, providing 1.79 TB/s of bandwidth. The memory clock is 1750 MHz, which translates to 28 Gbps effective.

The GPU's compute capabilities are substantial. It has 21,760 shading units, 680 texture mapping units, and 176 raster output units. The 170 ray tracing cores and 680 tensor cores provide hardware acceleration for advanced rendering features. The GPU delivers 104.8 TFLOPS of FP32 compute and 104.8 TFLOPS of FP16 compute. The pixel rate is 423.6 GPixel/s, and the texture rate is 1,636.8 GTexel/s.

In Rust, the GPU's role becomes more prominent as resolution increases. At 1080p, the CPU is the primary limiter, as evidenced by the relatively small performance delta between Medium (233 FPS) and High (197 FPS) compared to the larger delta between Low and Medium. At 4K, the GPU is the clear bottleneck, especially at Ultra settings where the average FPS drops to 61.

The GPU's benchmark scores reflect its position in the market. It scores 14,326 in 3DMark Steel Nomad DX12, 310,674 in Geekbench OpenCL, and 376,915 in Geekbench Vulkan. The Passmark G3D score is 44,065, and the Passmark GPU Compute score is 28,396. The GPU holds a 92nd percentile ranking against all GPUs, with an average benchmark score of 77,712.

The RTX 5090 D's 32 GB of VRAM is a significant asset for Rust. Even at 4K Ultra, the game's textures, draw distances, and entity counts are unlikely to exceed this capacity. The 1.79 TB/s of memory bandwidth ensures that the GPU can feed its 21,760 shading units without starving them, which is critical for maintaining the frame rates seen in the Medium and High presets at 4K. The GPU's launch MSRP is 2,299 USD.
