Rust

The Intel Core Ultra X9 388H paired with the NVIDIA GeForce RTX 5070 Ti Mobile produces a benchmark profile in Rust that is heavily dictated by resolution and preset selection. The data shows a system capable of high refresh rates at 1080p, but one that surrenders playability at 4K Ultra settings. The measured results indicate a clear performance tier structure, where the GPU becomes the dominant bottleneck at higher resolutions, while the CPU’s strong single-threaded capabilities keep frame rates high at lower graphical loads.

Resolution Scaling

The FPS drop from 1080p to 4K is substantial, revealing a classic GPU-bound scaling pattern. At Low settings, the average frame rate falls from 189 FPS at 1920x1080 to 130 FPS at 2560x1440, a decline of 59 FPS, and then further to 77 FPS at 3840x2160. This represents a 59% reduction from 1080p to 1440p, and a 41% reduction from 1440p to 4K. Such steep declines indicate that the RTX 5070 Ti Mobile’s rendering throughput is the primary constraint as pixel count rises, with the CPU having ample headroom to feed frames at lower resolutions.

The scaling at High settings follows a similar trajectory. The average FPS drops from 107 at 1080p to 74 at 1440p, a 31% decrease, and then to 44 at 4K, a 41% decrease from 1440p. The gap between the 1080p and 4K results at High (63 FPS difference) suggests that the game’s higher graphical presets amplify the GPU workload, making the resolution scaling more punishing. Notably, the 4K High result of 44 FPS is below the 4K Low result of 77 FPS, showing that preset choice at 4K has a more significant impact than resolution scaling alone.

At Medium settings, the data provides min and max FPS values, offering insight into frame pacing. At 1080p Medium, the average is 127 FPS with a min of 108 and max of 146, showing a 38 FPS spread. At 1440p Medium, the average drops to 87 FPS with a min of 74 and max of 101, a 27 FPS spread. At 4K Medium, the average is 52 FPS with a min of 44 and max of 59, a 15 FPS spread. This tightening of the min-max range as resolution increases indicates that the GPU is becoming consistently saturated, reducing the variance in frame times as it operates closer to its full capacity.

The Ultra preset results are the most demanding, with averages of 82 FPS at 1080p, 56 FPS at 1440p, and 33 FPS at 4K. The 4K Ultra result is the lowest in the entire dataset, showing that this combination struggles to maintain smooth gameplay under maximum graphical load at the highest resolution. The scaling from 1440p to 4K at Ultra (a 23 FPS drop) is proportionally similar to other presets, but the absolute values are too low for competitive play.

GPU Role

The NVIDIA GeForce RTX 5070 Ti Mobile, with its 12 GB of GDDR7 memory on a 192-bit bus, provides a memory bandwidth of 672.0 GB/s. This bandwidth figure is crucial for Rust, which often loads large textures and world data. The data suggests that at 1080p and 1440p, the GPU’s memory subsystem is sufficient, as frame rates scale predictably with preset changes. However, at 4K, the combination of higher pixel count and higher preset detail appears to overwhelm the GPU’s compute capabilities, as evidenced by the 33 FPS average at Ultra.

The GPU’s clock speeds—a base of 847 MHz and a boost of 1447 MHz—are relatively modest for a 50-series part, but the architecture’s efficiency compensates. The shading units (5888) and texture mapping units (184) drive the pixel rate of 115.8 GPixel/s and texture rate of 266.2 GTexel/s. These numbers explain why the GPU performs admirably at lower resolutions: it has enough raw throughput to handle 1080p and 1440p workloads with ease, as seen in the 189 FPS Low result at 1080p.

The GPU’s 80 ROPs are a limiting factor at 4K, where the fill rate demands are higher. The data shows that at 4K, even the Low preset (77 FPS) cannot reach the 1440p Low result (130 FPS), indicating that the ROP throughput is a bottleneck. The FP32 performance of 17.04 TFLOPS is respectable, but Rust’s rendering engine does not appear to be purely compute-bound; rather, it is the memory bandwidth and pixel processing that determine the scaling.

The GPU’s percentile ranking of 80th among all GPUs, with an average benchmark score of 35435, places it in a solid mid-to-high tier. Its nearest rival, the NVIDIA Quadro GV100, scores slightly higher at 35520, a delta of -0.2%, while the AMD Radeon Pro Duo scores 35860, a delta of -1.2%. These comparisons show that the RTX 5070 Ti Mobile is competitive with professional-grade cards, but its performance in Rust is more nuanced, with the 4K Ultra result of 33 FPS being a clear outlier compared to its synthetic benchmark strength.

CPU Role

The Intel Core Ultra X9 388H features 16 cores and 16 threads, a configuration that prioritizes single-thread performance over multi-threading. The base clock of 2.10 GHz and boost clock of 5.10 GHz are key to its gaming performance. Rust is known for being CPU-intensive, particularly in its simulation and physics calculations, and the data reflects this. At 1080p Low, the average FPS of 189 suggests that the CPU is able to feed the GPU efficiently, with the high boost clock ensuring quick response times.

The CPU’s cache hierarchy—192 KB of L1 per core, 3 MB of L2 per core, and 18 MB of shared L3—provides low-latency access to frequently used data. The benchmark results for this CPU show a PassMark single-thread score of 4280 and a Cinebench R23 single-core score of 2200.5. These scores are indicative of strong single-threaded capability, which is essential for Rust’s main game thread. The CPU’s percentile ranking of 88th among all CPUs, with an average benchmark score of 44466, places it in the top tier for overall processing power.

However, the CPU’s multi-threaded scores are less impressive relative to its single-thread performance. The Cinebench R23 multicore score of 18911 and PassMark multithread score of 36811 show that while it can handle parallel workloads, its 16 threads without hyper-threading limit its scaling. In Rust, this means that the CPU does not become a bottleneck at lower resolutions, as the single-thread performance is sufficient to drive high frame rates. At 4K Ultra, the CPU’s role diminishes further, as the GPU becomes the limiting factor, allowing the CPU to idle with headroom.

The nearest rival comparisons for the CPU show it is closely matched with the AMD Ryzen 5 7500X3D, which scores 44573, a delta of -0.2%, and the Intel Core i9-13950HX, which scores 44342, a delta of 0.3%. These results indicate that the Ultra X9 388H is competitive with other high-end processors, but its performance in Rust is more dependent on the GPU at higher resolutions. The data shows no evidence of CPU bottlenecking at 1080p, as the frame rates scale linearly with GPU load.

Measured FPS Breakdown

At 1920x1080, the data shows a clear progression across presets. The Low preset averages 189 FPS, which is the highest result in the entire dataset. The Medium preset averages 127 FPS, with a minimum of 108 FPS and a maximum of 146 FPS, showing a 38 FPS variance. The High preset averages 107 FPS, and the Ultra preset averages 82 FPS. This 107 FPS spread from Low to Ultra at 1080p indicates that the GPU is the limiting factor, as the CPU can maintain high frame rates even at Low settings.

At 2560x1440, the frame rates drop significantly. The Low preset averages 130 FPS, which is still high, but 59 FPS lower than the 1080p Low result. The Medium preset averages 87 FPS, with a minimum of 74 FPS and a maximum of 101 FPS. The High preset averages 74 FPS, which is exactly the same as the minimum for Medium, suggesting that the medium preset’s variance is driven by GPU load spikes. The Ultra preset averages 56 FPS, which is below the 60 FPS threshold for smooth gameplay.

At 3840x2160, the results are the most demanding. The Low preset averages 77 FPS, which is playable but not ideal. The Medium preset averages 52 FPS, with a minimum of 44 FPS and a maximum of 59 FPS, showing a tight 15 FPS range. The High preset averages 44 FPS, which matches the minimum for Medium, indicating that the GPU is consistently saturated. The Ultra preset averages 33 FPS, which is the lowest result in the dataset and not suitable for competitive play.

The Medium preset across all resolutions provides the most complete dataset, with min and max values. At 1080p, the range is 108-146 FPS, at 1440p, it is 74-101 FPS, and at 4K, it is 44-59 FPS. This shows that as resolution increases, the frame time variance decreases, but the average frame rate also decreases. The data suggests that Medium is a balanced preset for this combo, providing playable frame rates at 1440p while maintaining consistency.

Settings Recommendations

Based on the measured data, the optimal preset for this combination depends on the target resolution. At 1920x1080, the High preset (107 FPS) offers a good balance between visual fidelity and performance, while the Ultra preset (82 FPS) is still playable for most users. The Low preset (189 FPS) is excessive for a 60Hz display but suitable for high-refresh-rate monitors. For competitive play at 1080p, the Medium preset (127 FPS) provides a high frame rate with a consistent minimum of 108 FPS.

At 2560x1440, the Medium preset (87 FPS) is the best choice, as it maintains an average above 60 FPS with a minimum of 74 FPS. The High preset (74 FPS) is also viable, but the lower minimum frame rate (as seen in the 1440p Medium min of 74 FPS) suggests that High may dip below 60 FPS in demanding scenes. The Ultra preset (56 FPS) is not recommended for 1440p, as it falls below the 60 FPS threshold.

At 3840x2160, only the Low preset (77 FPS) provides a playable average frame rate. The Medium preset (52 FPS) is borderline, and the High (44 FPS) and Ultra (33 FPS) presets are not suitable for smooth gameplay. For 4K, users should prioritize the Low preset to maintain a minimum frame rate above 60 FPS, sacrificing visual quality for performance. The data shows that the GPU is the limiting factor at 4K, so reducing preset is more effective than lowering resolution.

The overall recommendation is to use Medium settings for the best experience across all resolutions, as it provides the most consistent frame pacing (as evidenced by the min and max data) and acceptable average frame rates. At 1080p, Medium (127 FPS) is better than High (107 FPS) for high-refresh displays. At 1440p, Medium (87 FPS) is the only preset that guarantees a minimum above 60 FPS. At 4K, Medium (52 FPS) is not ideal, but it is the highest setting that remains partially playable, while Low (77 FPS) is the recommended choice.

How This Combo Ranks

The combination of the Intel Core Ultra X9 388H and NVIDIA GeForce RTX 5070 Ti Mobile ranks 1412 out of 3723 tested combos in Rust, placing it in the top 38% of all configurations. This ranking is lower than what the individual component benchmarks might suggest, given that the CPU ranks in the 88th percentile and the GPU in the 80th percentile. The discrepancy is due to Rust’s demanding nature at high resolutions and the GPU’s relatively modest performance at 4K.

The combo’s rank is influenced by the 4K Ultra result of 33 FPS, which is a significant outlier compared to the 1080p results. Many other combos with higher-end GPUs, such as those with more VRAM or higher clock speeds, can achieve better 4K performance. The RTX 5070 Ti Mobile’s 12 GB VRAM is sufficient for 1080p and 1440p, but at 4K, the memory bandwidth of 672.0 GB/s and the 192-bit bus become limiting factors.

Compared to the CPU’s nearest rivals, the combo’s performance is competitive at 1080p but lags at 4K. The CPU’s delta of -0.2% versus the AMD Ryzen 5 7500X3D indicates similar CPU performance, but the GPU is the deciding factor in Rust. The GPU’s delta of -0.2% versus the NVIDIA Quadro GV100 shows they are closely matched in synthetic benchmarks, but the GV100’s higher memory bandwidth (if applicable) may give it an edge in 4K gaming.

The rank of 1412 out of 3723 suggests that while this combo is above average, it is not top-tier for Rust specifically. The data shows that the system excels at 1080p and 1440p, where it can deliver high frame rates, but it struggles to maintain playable performance at 4K Ultra. Users targeting 4K should consider lower presets or a more powerful GPU, while those playing at 1080p or 1440p will find this combo well-suited for Rust. The benchmark results indicate that the combo is balanced for mainstream gaming but not optimized for extreme resolutions.
