Resolution Scaling

The measured FPS data for Rust with the Intel Core Ultra 5 135H and NVIDIA GeForce RTX 5090 shows a clear progression as resolution increases, but the scaling pattern reveals an interesting dynamic between the CPU and GPU. At 1920x1080 with Low settings, the combo produces 204 FPS average, while the same settings at 2560x1440 drop to 163 FPS, and at 3840x2160 they fall further to 96 FPS. That represents a 20% drop from 1080p to 1440p, and another 41% drop from 1440p to 4K. The scaling from Low to High settings at each resolution tells a similar story: at 1080p, High settings deliver 134 FPS versus 204 FPS on Low, a 34% reduction; at 1440p, High produces 92 FPS versus 163 FPS on Low, a 44% reduction; and at 4K, High yields 54 FPS versus 96 FPS on Low, a 44% reduction as well.

The fact that the percentage drop from Low to High settings remains nearly identical when moving from 1440p to 4K suggests that the GPU is becoming the limiting factor at higher resolutions, whereas at 1080p the gap is smaller because the CPU has more headroom to keep frame rates elevated. The RTX 5090's massive 32 GB of GDDR7 memory and 1.79 TB/s bandwidth are clearly not the constraint here — even at 4K Ultra, the combo maintains 41 FPS average, which is playable for a survival title. The Ultra preset at 1080p delivers 102 FPS, which is 24% lower than High at the same resolution, indicating that the Ultra preset adds significant graphical load that scales with resolution.

Looking at the Medium preset, which is the only setting with min/max FPS data recorded, the pattern holds: at 1080p Medium, the range is 135-183 FPS with a 159 FPS average; at 1440p Medium, it drops to 93-126 FPS with a 109 FPS average; and at 4K Medium, it falls to 55-74 FPS with a 65 FPS average. The min FPS at 4K Medium (55 FPS) is still above the average FPS for 4K Ultra (41 FPS), which underscores how much headroom the Medium preset provides. The data indicates that this combo is heavily GPU-bound at 4K, given that the RTX 5090's 104.8 TFLOPS FP32 throughput and 423.6 GPixel/s pixel rate are being taxed by Rust's geometry and shading demands at that resolution.

How This Combo Ranks

The Intel Core Ultra 5 135H paired with the NVIDIA GeForce RTX 5090 ranks 536 out of 2953 tested combos in Rust specifically. That places this configuration in the top 18% of all combinations tested for this game, which is a strong showing given that the CPU is a mobile part with a 28 W TDP. The CPU itself sits at the 81st percentile among all processors, with an average benchmark score of 29093. Its nearest rivals include the AMD Ryzen 7 5800X (avg score 29123, delta -0.1%), the Intel Xeon Phi 7210 (avg score 29245, delta -0.5%), the AMD Ryzen 5 5600XT (avg score 28940, delta 0.5%), and the Intel Core i5-13500HX (avg score 29270, delta -0.6%). The Ultra 5 135H is essentially within 0.6% of all four rivals, meaning its compute performance is statistically indistinguishable from those desktop and mobile parts.

For the GPU, the RTX 5090 sits at the 92nd percentile among all GPUs with an average benchmark score of 79842. Its nearest rivals are the NVIDIA Tesla P100 PCIe 16 GB (avg score 79605, delta 0.3%), the NVIDIA Tesla P100 PCIe 12 GB (avg score 79396, delta 0.6%), the AMD Radeon RX 6850M XT (avg score 78940, delta 1.1%), and the AMD Radeon Pro Vega 64X (avg score 80959, delta -1.4%). The RTX 5090 leads three of its four nearest rivals, with only the Pro Vega 64X edging it out by 1.4%. This GPU is clearly a top-tier part, and the combo rank of 536 reflects that the bottleneck in Rust is more likely the CPU than the GPU, especially at lower resolutions where the CPU must feed frames faster.

The combo rank being 536 out of 2953 means there are 535 combinations that perform better in Rust, but given the mobile CPU's modest compute scores — its Cinebench R23 multicore score is 11875.5 and single-core is 1700 — the ranking is respectable. The data suggests that in CPU-bound scenarios like low-resolution Rust gameplay, the Ultra 5 135H's 14 cores and 18 threads are sufficient to keep the RTX 5090 fed, but the GPU's potential is not fully unleashed at 1080p, as evidenced by the 204 FPS ceiling on Low settings.

FAQ

A: Out of 2953 tested combinations, this pairing ranks 536th. The RTX 5090 sits at the 92nd percentile among GPUs, while the Ultra 5 135H sits at the 81st percentile among CPUs. The gap between the GPU's high percentile and the CPU's lower percentile explains why the combo rank is not higher — the CPU is the weaker link in this pairing.

Q: Is the RTX 5090's performance in Rust consistent with its overall benchmark standing?

A: The GPU's average benchmark score of 79842 places it at the 92nd percentile, and its nearest rivals are all within 1.4% of its score. In Rust specifically, the combo's 536th rank out of 2953 suggests the GPU is performing as expected, but the CPU's 14-core Meteor Lake architecture with an 18 MB shared L3 cache may not be delivering frames fast enough to fully utilize the GPU at 1080p.

Measured FPS Breakdown

The measured FPS data covers three resolutions and four settings presets, with Medium being the only preset that includes min and max FPS values. At 1920x1080, the Low preset delivers 204 FPS average, which is the highest frame rate recorded for this combo. The Medium preset at 1080p produces 159 FPS average with a range of 135-183 FPS. High settings at 1080p yield 134 FPS average, while Ultra drops to 102 FPS average. This scaling shows that at 1080p, the combo can push well beyond 200 FPS on Low, and even Ultra remains above 100 FPS, indicating that the CPU is the primary limiter at this resolution.

Moving to 2560x1440, the Low preset delivers 163 FPS average, which is 41 FPS lower than at 1080p. Medium at 1440p produces 109 FPS average with a range of 93-126 FPS. High settings at 1440p yield 92 FPS average, and Ultra drops to 70 FPS average. The gap between Low and Ultra at 1440p is 93 FPS, compared to 102 FPS at 1080p, showing that the GPU is starting to take on more of the workload as resolution increases. The 1440p Medium range of 93-126 FPS indicates that even the minimum frame rate stays above 90 FPS, which is excellent for a survival game with frequent structure rendering.

At 3840x2160, the Low preset delivers 96 FPS average, which is still above 60 FPS and playable. Medium at 4K produces 65 FPS average with a range of 55-74 FPS, meaning the minimum frame rate dips below 60 FPS but only marginally. High settings at 4K drop to 54 FPS average, and Ultra falls to 41 FPS average. The progression from Low to Ultra at 4K shows a 55 FPS difference, and the fact that High and Ultra both fall below 60 FPS suggests that 4K gaming with this combo requires Medium settings or lower for a consistently smooth experience. The Medium preset at 4K offers the best compromise, with an average of 65 FPS and a minimum of 55 FPS, which is acceptable for Rust's slower-paced gameplay.

GPU Role

The NVIDIA GeForce RTX 5090 is a Blackwell 2.0 architecture GPU built on a 5 nm process at TSMC, with 92,200 million transistors and a die size of 750 mm². Its base clock is 2017 MHz with a boost clock of 2407 MHz, and it features 21760 shading units, 680 TMUs, and 176 ROPs. The memory configuration is 32 GB of GDDR7 on a 512-bit bus, delivering 1.79 TB/s of bandwidth. These specifications put the GPU at the 92nd percentile among all GPUs, with an average benchmark score of 79842.

In Rust, the GPU's role becomes increasingly important as resolution and settings increase. At 1080p Low, the combo achieves 204 FPS, which is likely CPU-limited given the Ultra 5 135H's 14 cores and 18 threads. But at 4K Ultra, the combo drops to 41 FPS, indicating that the GPU's compute resources are being fully taxed. The RTX 5090's 104.8 TFLOPS FP32 throughput and 423.6 GPixel/s pixel rate are substantial, but Rust's rendering engine at 4K Ultra with 176 ROPs still cannot maintain high frame rates. The GPU's 32 GB VRAM is never a constraint — even at 4K Ultra, memory capacity is not the limiting factor.

The GPU's benchmark results show strong performance across different APIs: a 3DMark Steel Nomad DX12 score of 18355, a Geekbench OpenCL score of 334370, and a Geekbench Vulkan score of 376728. These scores place the RTX 5090 above rivals like the AMD Radeon RX 6850M XT (delta 1.1%) and NVIDIA Tesla P100 PCIe 16 GB (delta 0.3%). The GPU's PassMark G3D score of 39650 further confirms its high-end positioning. In Rust, the GPU's performance is consistent with its overall standing, but the combo rank of 536 out of 2953 suggests that pairing this top-tier GPU with a mobile CPU limits its potential in CPU-bound scenarios.

Settings Recommendations

Based on the measured FPS data, the optimal settings depend heavily on the target resolution and desired frame rate. At 1920x1080, all four presets deliver playable frame rates, with Low at 204 FPS, Medium at 159 FPS, High at 134 FPS, and Ultra at 102 FPS. The data shows that High settings at 1080p provide a 134 FPS average, which is well above the 60 FPS threshold and offers good visual quality. Ultra at 1080p still delivers 102 FPS, so players with high-refresh monitors can comfortably use Ultra at this resolution. The Medium preset's range of 135-183 FPS at 1080p indicates that even the minimum frame rate stays well above 100 FPS, making it a safe choice for competitive play.

At 2560x1440, the Medium preset delivers 109 FPS average with a range of 93-126 FPS, making it the recommended choice for a smooth experience. High settings at 1440p drop to 92 FPS average, which is still acceptable, but the margin above 60 FPS is thinner. Ultra at 1440p produces 70 FPS average, which is playable but leaves less headroom for complex scenes. Low at 1440p delivers 163 FPS, but the visual quality trade-off is significant. For 1440p, Medium is the sweet spot — it maintains an average above 100 FPS with a minimum of 93 FPS, ensuring consistent performance during base building and PvP encounters.

At 3840x2160, the Medium preset is the only setting that maintains an average above 60 FPS, delivering 65 FPS with a range of 55-74 FPS. Low at 4K produces 96 FPS average, which is smooth, but the visual downgrade may be too severe for a game like Rust where visibility matters. High at 4K drops to 54 FPS average, and Ultra falls to 41 FPS, both of which are below the 60 FPS threshold. For 4K gaming, Medium is the recommended preset — it provides the best balance of visual quality and frame rate, with an average of 65 FPS that keeps gameplay fluid. Players who prioritize frame rate over visuals can use Low at 4K for 96 FPS, but the Medium preset's min FPS of 55 suggests it handles demanding scenes adequately.
