# Rust Performance Analysis: Intel Core Ultra 7 155H + NVIDIA GeForce RTX 5070 Mobile

This combination of the Intel Core Ultra 7 155H and NVIDIA GeForce RTX 5070 Mobile ranks 2,061 out of 3,723 tested combos in Rust, placing it in the lower-middle portion of the performance distribution. The CPU sits at the 83rd percentile among all processors, while the GPU ranks at the 75th percentile among all graphics cards, yet the overall combo ranking suggests that Rust's specific demands prevent this pairing from reaching the upper echelons. The measured frame rates across resolutions and settings reveal a system that is capable but constrained, with particularly notable limitations at 4K Ultra where average FPS drops to 28.

How This Combo Ranks

The combo rank of 2,061 out of 3,723 represents the 55.4th percentile of tested combinations, meaning roughly 55% of systems outperform this pairing in Rust. This is surprising given the individual component percentiles — the CPU at 83rd and GPU at 75th — but it indicates that Rust's engine presents challenges that neither component fully overcomes. The Intel Core Ultra 7 155H's nearest rivals include the Intel Core i5-14600T with an average benchmark score of 32,707 (0% delta), the AMD Ryzen AI 7 PRO 360 at 32,662 (0.1% faster), the AMD Ryzen 5 7400F at 32,750 (0.2% slower), and the AMD Ryzen 7 PRO 6850H at 32,812 (0.4% slower). These near-identical scores suggest the CPU's compute performance is well-matched to its peers.

For the GPU, the NVIDIA GeForce RTX 5070 Mobile's nearest rivals are the NVIDIA GeForce RTX 3070 Ti with an average score of 29,945 (0.1% faster), the NVIDIA GeForce RTX 2080 Ti at 29,783 (0.5% slower), the AMD Radeon RX 6800 at 30,095 (0.6% faster), and the AMD Radeon RX 6700 at 30,433 (1.7% faster). The RTX 5070 Mobile's average benchmark score of 29,928 places it within a tight cluster of previous-generation high-end cards, indicating that its Blackwell architecture provides comparable raw compute to established desktop-class GPUs.

The discrepancy between component-level and combo-level rankings points to Rust's unique performance profile. At 1080p Low, the system achieves 161 FPS average, which is solidly playable, but at 4K Ultra, the average drops to 28 FPS, which is below the threshold for smooth gameplay. The data suggests that neither the CPU's 16 cores and 22 threads nor the GPU's 8 GB of GDDR7 memory is sufficient to fully saturate Rust's demanding rendering pipeline at higher settings.

Settings Recommendations

The measured FPS data provides clear guidance for optimal settings at each resolution. At 1920x1080, the Low preset delivers 161 FPS average, which is ideal for high-refresh-rate displays. The Medium preset at 108 FPS average remains competitive, while High drops to 91 FPS and Ultra falls to 69 FPS. For competitive play where frame rate matters most, 1080p Low is the clear choice, but for visually richer experiences, Medium offers a strong balance.

At 2560x1440, the Low preset yields 111 FPS average, which remains smooth for most displays. Medium drops to 74 FPS, High to 63 FPS, and Ultra to 48 FPS. The 1440p Medium setting appears to be the sweet spot, providing acceptable frame rates while maintaining visual quality. The 4K resolution tells a different story: Low achieves 65 FPS, Medium 44 FPS, High 37 FPS, and Ultra just 28 FPS. At 3840x2160, only the Low preset provides a consistently playable experience, and even that requires some tolerance for reduced visual fidelity.

The data indicates that this combo is best utilized at 1080p with Medium or High settings, or at 1440p with Low or Medium. Pushing to 4K with anything above Low will result in frame rates that fall below the 60 FPS threshold many players consider minimum for smooth gameplay. The 4K Ultra figure of 28 FPS average is particularly telling — this is a scenario where the combination struggles significantly, likely due to both GPU memory bandwidth limitations and the CPU's inability to feed the GPU effectively at higher resolutions.

Measured FPS Breakdown

At 1920x1080, the system demonstrates its strongest performance. The Low preset achieves an average of 161 FPS, representing the highest measured frame rate across all configurations. Medium follows at 108 FPS with a minimum of 92 and maximum of 124 FPS, showing consistent frame delivery. High drops to 91 FPS average, and Ultra falls to 69 FPS. The scaling from Low to Ultra at 1080p shows a 57% reduction in frame rate, indicating that the GPU becomes increasingly stressed as settings rise.

The 2560x1440 resolution shows a similar pattern with reduced absolute values. Low delivers 111 FPS average, Medium provides 74 FPS (minimum 63, maximum 85), High reaches 63 FPS, and Ultra drops to 48 FPS. The delta between Low and Ultra at 1440p is also 57%, matching the 1080p scaling pattern. This consistency suggests that the performance penalty from settings changes is resolution-independent for this combo.

At 3840x2160, the system's limitations become evident. Low achieves 65 FPS, Medium 44 FPS (minimum 37, maximum 50), High 37 FPS, and Ultra just 28 FPS. The 4K Low to Ultra scaling shows a 57% drop, consistent with other resolutions, but the absolute values are significantly lower. The minimum FPS of 37 at 4K Medium highlights the potential for stuttering during intense gameplay moments.

The data across all resolutions shows a consistent pattern: the gap between Low and Medium averages roughly 33%, while the gap between Medium and High averages roughly 15-16%, and the gap between High and Ultra averages roughly 24%. This non-linear scaling suggests that the Medium preset hits a performance sweet spot where the GPU's resources are efficiently utilized without hitting bottlenecks.

GPU Role

The NVIDIA GeForce RTX 5070 Mobile features 8 GB of GDDR7 memory on a 128-bit bus, providing 384.0 GB/s of bandwidth. The GPU has 4,608 shading units, 144 texture mapping units, and 48 raster output pipelines. Its base clock runs at 907 MHz with a boost clock of 1,425 MHz, and memory operates at 1,500 MHz with 24 Gbps effective speed. The chip, designated GB206, is built on TSMC's 5 nm process with 21,900 million transistors on a 181 mm² die.

The GPU's pixel rate of 68.40 GPixel/s and texture rate of 205.2 GTexel/s provide the raw throughput needed for Rust's rendering demands. The FP32 performance of 13.13 TFLOPS places this GPU in a competitive position for rasterized workloads. The 36 RT cores and 144 tensor cores support hardware-accelerated ray tracing and AI features, though Rust's primary rendering path is traditional rasterization.

The measured FPS data shows that the GPU becomes the limiting factor at higher resolutions and settings. At 4K Ultra, the 28 FPS average suggests the GPU is overwhelmed by the combination of high pixel count and maximum visual effects. The 8 GB VRAM capacity may also constrain performance at 4K Ultra, where texture memory requirements can exceed this amount. The memory bandwidth of 384.0 GB/s, while substantial, may not be sufficient for the most demanding scenarios.

The GPU's benchmark scores provide context: it achieves 122,238 in Geekbench OpenCL and 116,960 in Geekbench Vulkan, with a Passmark G3D score of 20,355. These figures place it at the 75th percentile among all GPUs. The nearest rival comparisons show performance parity with the RTX 3070 Ti (0.1% faster) and RTX 2080 Ti (0.5% slower), indicating that the RTX 5070 Mobile offers performance comparable to previous-generation high-end cards.

CPU Role

The Intel Core Ultra 7 155H features 16 cores and 22 threads, with a base clock of 3.80 GHz and boost clock of 4.80 GHz. The CPU operates within a 28 W TDP envelope and uses the Intel BGA 2049 socket. Its Meteor Lake architecture is built on Intel's 7 nm process. The cache hierarchy includes 112 KB L1 per core, 2 MB L2 per core, and 24 MB shared L3 cache. Memory support includes DDR5 with dual-channel configuration providing 89.6 GB/s bandwidth.

The CPU's benchmark performance shows strong multi-threaded capability with a Cinebench R23 multi-core score of 15,028 and single-core score of 1,743. The Passmark multi-thread score of 24,873 and single-thread score of 3,468 further demonstrate balanced performance. The average benchmark score of 32,697 places it at the 83rd percentile among all CPUs, with rival comparisons showing near-identical performance to several other mid-range processors.

In Rust, the CPU's role is critical for game logic, physics calculations, and entity management. The 16 cores and 22 threads provide ample parallel processing capability, while the 4.80 GHz boost clock ensures responsive single-threaded performance for the primary game thread. The 24 MB L3 cache helps reduce memory latency for frequently accessed data. The CPU's 89.6 GB/s memory bandwidth, while not exceptional, is sufficient for feeding the GPU at most settings.

The measured FPS data suggests the CPU maintains adequate performance across all tested configurations. At 1080p Low, the 161 FPS average indicates the CPU can drive high frame rates when GPU load is moderate. However, the scaling from 1080p to 4K at the same settings reveals where the CPU's influence wanes. The fact that 4K Low (65 FPS) is only 60% of 1080p Low (161 FPS) suggests the GPU becomes the primary bottleneck at higher resolutions.

Resolution Scaling

The transition from 1080p to 4K at each settings preset reveals important insights about the system's bottleneck characteristics. At Low settings, the frame rate drops from 161 FPS at 1080p to 111 FPS at 1440p (31% decrease) and then to 65 FPS at 4K (41% decrease from 1440p). This represents a total 60% reduction from 1080p to 4K. At Medium settings, the progression is 108 FPS to 74 FPS (31% decrease) to 44 FPS (41% decrease), totaling 59% reduction. High settings show 91 FPS to 63 FPS (31% decrease) to 37 FPS (41% decrease), for a 59% total reduction. Ultra settings follow the same pattern: 69 FPS to 48 FPS (30% decrease) to 28 FPS (42% decrease), totaling 59% reduction.

The consistent ~60% reduction from 1080p to 4K across all settings indicates that resolution scaling has a uniform impact regardless of preset. This pattern suggests the GPU is the primary limiting factor, as the pixel count increases by 4x from 1080p to 4K, but frame rates only decrease by roughly 2.5x. This less-than-linear scaling implies that other bottlenecks, possibly CPU-bound game logic or memory bandwidth limitations, prevent the GPU from being fully utilized at lower resolutions.

The data reveals that the system is reasonably well-balanced at 1080p and 1440p, where both CPU and GPU contribute to performance. At 4K, the GPU becomes the dominant constraint, as evidenced by the dramatic frame rate drops. The 37 FPS minimum at 4K Medium highlights the potential for noticeable stuttering during complex scenes. For players seeking consistent performance, the 1080p and 1440p resolutions offer the best experience, with the 1440p Medium preset providing a good balance of visual quality and frame rate stability.
