GPU Role

The NVIDIA GeForce RTX 5090 Mobile brings substantial resources to Rust. It features 24 GB of GDDR7 memory on a 256-bit bus, yielding a bandwidth of 896.0 GB/s. This is a massive amount of memory bandwidth for a mobile GPU, and Rust’s open-world environments with many entities and structures can benefit from fast memory access. The GPU runs at a base clock of 990 MHz and boosts to 1,515 MHz, with memory clocked at 1,750 MHz (28 Gbps effective).

The GPU’s 10,496 shading units, 328 texture mapping units, and 112 raster operation units provide a strong foundation for rasterization-heavy workloads. Rust is not particularly demanding on ray tracing, but the 82 RT cores present could help in future updates. The GPU’s FP32 performance of 31.80 TFLOPS indicates a high compute capability, which translates to smooth frame rendering at high resolutions.

The GPU’s benchmark results reinforce its capability. Its PassMark G3D score of 30,034 and 3DMark Steel Nomad DX12 score of 5,871 show strong synthetic performance. The Geekbench Vulkan score of 198,405 and OpenCL score of 201,834 are also impressive, suggesting the GPU can handle diverse workloads. In Rust, the measured FPS data shows the GPU can push high frame rates at 1080p, but at 4K Ultra, the average FPS drops to 41, indicating the GPU is the limiting factor at the highest settings and resolution.

CPU Role

The Intel Core Ultra 7 155H is a Meteor Lake architecture processor with 16 cores and 22 threads. It runs at a base clock of 3.80 GHz and boosts to 4.80 GHz, with a TDP of 28 W. The CPU’s cache hierarchy includes 112 KB of L1 per core, 2 MB of L2 per core, and 24 MB of shared L3 cache. This cache configuration is important for Rust, which has complex simulation logic and many entities that can stress the CPU.

The CPU’s benchmark scores indicate strong multi-threaded performance. Its Cinebench R23 multi-core score of 15,028 and single-core score of 1,743 show a balanced profile. The PassMark multithread score of 24,873 and single-thread score of 3,468 further confirm this. The CPU’s 83rd percentile ranking among all CPUs means it outperforms the majority of processors, though it is not a flagship part.

In Rust, the CPU’s role becomes more pronounced at lower resolutions where the GPU is less stressed. The data shows that at 1080p Low, the average FPS is 201, which is likely CPU-bound. The CPU’s 16 cores and 22 threads can handle Rust’s simulation threads, but the game’s single-threaded aspects may limit performance. The CPU’s nearest rivals, including the Intel Core i5-14600T with a delta of 0% and the AMD Ryzen 7 PRO 6850H with a delta of -0.4%, show that the 155H is competitive but not exceptional in its class.

Measured FPS Breakdown

The measured FPS data provides a clear picture of how this combo performs across resolutions and settings. At 1920x1080, the average FPS ranges from 102 at Ultra to 201 at Low. The Medium setting yields an average of 159 FPS with a minimum of 135 and maximum of 183. High settings deliver 134 FPS average. These numbers indicate that at 1080p, the combo is well-suited for high-refresh-rate gaming, with even Ultra settings maintaining above 100 FPS.

Moving to 2560x1440, the performance drops as expected. Low settings deliver an average of 163 FPS, while High yields 92 FPS. Medium settings show an average of 109 FPS with a minimum of 93 and maximum of 126. Ultra settings fall to 70 FPS average. The data shows a consistent scaling pattern, with each settings tier reducing FPS by roughly 20-30% at this resolution.

At 3840x2160, the GPU is clearly the bottleneck. Low settings produce an average of 96 FPS, which is still playable. Medium settings drop to 65 FPS with a minimum of 55 and maximum of 74. High settings yield 54 FPS, and Ultra falls to 41 FPS. These numbers indicate that 4K gaming is possible but requires lowering settings to maintain smooth gameplay. The gap between Low and Ultra at 4K is significant, with Ultra delivering less than half the FPS of Low.

The Medium settings rows provide the only min/max data in the pack. At 1080p Medium, the minimum of 135 FPS and maximum of 183 FPS show a range of 48 FPS, indicating some frame-time variance. At 1440p Medium, the range is 33 FPS (93 to 126), and at 4K Medium, the range is 19 FPS (55 to 74). This tightening range at higher resolutions suggests that the GPU becomes more consistently loaded, reducing frame-time spikes.

Q: Is the CPU or GPU more important for Rust performance?

A: The data indicates that the GPU becomes the limiting factor at higher resolutions and settings. At 4K Ultra, the average FPS is 41, while at 1080p Low, it is 201. The CPU’s strong multi-core performance (Cinebench R23 multi-core score of 15,028) helps at lower resolutions, but the GPU’s workload scales with resolution. At 1080p, the CPU is likely the bottleneck, while at 4K, the GPU is clearly the constraint.

Settings Recommendations

The measured FPS data suggests that the Medium preset offers the best balance between visual quality and performance. At 1080p Medium, the average FPS is 159, which is high enough for smooth gameplay on most displays. The min/max range of 135 to 183 FPS indicates that the experience is mostly consistent, with only occasional dips. At 1440p Medium, the average drops to 109 FPS with a range of 93 to 126, which is still playable for most users.

For users with high-refresh-rate monitors (144Hz or higher), Low settings at 1080p deliver an average of 201 FPS, which is ideal for competitive play. However, the visual quality reduction may be noticeable. High settings at 1080p provide 134 FPS, which is a good middle ground for those who want better visuals without sacrificing too much frame rate.

At 4K, the Medium preset yields an average of 65 FPS with a range of 55 to 74. This is borderline for smooth gameplay, and users may want to consider Low settings, which produce 96 FPS average. Ultra settings at 4K are not recommended, as the 41 FPS average is below the 60 FPS threshold for most players. The data clearly shows that Medium is the sweet spot for this combo across all resolutions.

Resolution Scaling

The FPS scaling from 1080p to 4K reveals important insights about the limiting component. At Low settings, the average FPS drops from 201 at 1080p to 163 at 1440p and 96 at 4K. This represents a 19% drop from 1080p to 1440p and a 52% drop from 1080p to 4K. At High settings, the drops are from 134 to 92 to 54, which is a 31% drop from 1080p to 1440p and a 60% drop from 1080p to 4K.

The scaling pattern indicates that the GPU becomes increasingly dominant as resolution increases. At 1080p, the CPU can keep up with the GPU’s output, allowing for high frame rates. As resolution rises, the GPU’s rendering workload increases, and the FPS drops accordingly. The fact that the FPS does not scale linearly with pixel count (4K has 4x the pixels of 1080p, but FPS drops by only about half) suggests that the GPU has enough bandwidth and compute headroom to partially offset the resolution increase.

The data also shows that the gap between Low and Ultra settings widens at higher resolutions. At 1080p, the difference between Low and Ultra is 99 FPS (201 vs 102). At 1440p, the difference is 93 FPS (163 vs 70). At 4K, the difference is 55 FPS (96 vs 41). This indicates that the GPU’s performance headroom is more limited at 4K, where even lowering settings from Ultra to Low does not fully compensate for the resolution penalty. The 24 GB of VRAM is not a limiting factor in Rust, but the GPU’s raw compute power is the primary constraint at 4K.
