Rust

The Intel Core Ultra 5 235 brings a 14-core, 14-thread Arrow Lake design to Rust, while the GeForce GTX 1660 Ti is a Turing-based card with 6 GB of VRAM. When paired, this combination delivers playable frame rates at 1080p in most settings, but struggles to maintain smooth performance at higher resolutions. The benchmark data reveals a system where the GPU becomes the clear bottleneck as resolution climbs, yet the CPU’s architecture and clock speeds still play a decisive role in the game’s demanding simulation and physics workloads. This analysis breaks down the measured FPS across resolutions and settings, contextualizes the combo’s rank among 2,953 tested configurations, and provides actionable settings guidance based strictly on the data.

CPU Role — cores, clocks, and how they relate to this game's results

The Intel Core Ultra 5 235 operates with a base clock of 3.40 GHz and a boost clock of 5.00 GHz, with 14 cores and 14 threads. This configuration is noteworthy because it lacks hyper-threading, meaning each core handles a single thread. For a game like Rust, which is known for heavy server-side and client-side simulation workloads, the absence of multi-threading could theoretically limit parallel task efficiency. However, the benchmark data shows the CPU performs strongly in synthetic tests: it scores 14,769 in Cinebench R23 multi-core and 2,085 in single-core, placing it in the 89th percentile of all CPUs.

The CPU’s performance relative to its nearest rivals is tight. The AMD Ryzen AI 9 HX 375 averages a score of 46,030, which is only 0.1% lower than the Ultra 5 235’s average benchmark score of 46,062. The Intel Core i9-13900HX is essentially a dead heat, with an average score of 46,098, representing a -0.1% delta. This tells us that in raw processing power, the Ultra 5 235 is competitive with high-end mobile and desktop parts, but the real question is how that translates to Rust’s frame rates. The measured FPS data indicates that at 1080p Low, the combo reaches 106 FPS, suggesting the CPU is not the primary limiter at lower graphical loads. At 4K Ultra, the frame rate drops to 19 FPS, a massive reduction that points to the GPU as the constraining factor, not the CPU.

The L3 cache is 24 MB shared, which is ample for gaming workloads that benefit from large data sets being quickly accessible. The CPU’s memory bandwidth is rated at 102.4 GB/s over dual-channel DDR5, which is another factor that can influence Rust’s performance, particularly when many entities are loaded into memory. While the data does not directly isolate CPU vs. GPU bottleneck percentages, the pattern of FPS scaling — from 106 FPS at 1080p Low to 43 FPS at 4K Low — strongly implies that the CPU can handle the game’s logic at high frame rates, but the GPU fails to keep pace when pixel count increases. This is consistent with the CPU’s high percentile rank (89%) and its strong single-core score of 2,085 in Cinebench R23, which is often more critical for game simulation that is not perfectly multi-threaded.

GPU Role — VRAM, clocks, and how they relate to this game's results

The NVIDIA GeForce GTX 1660 Ti is built on the Turing architecture with a 12 nm process node, featuring 1,536 shading units and 48 ROPs. Its memory configuration is 6 GB of GDDR6 on a 192-bit bus, providing 288.0 GB/s of bandwidth. The base clock is 1500 MHz with a boost of 1770 MHz, while the memory runs at an effective speed of 12 Gbps. These specifications place the GPU in the 41st percentile of all GPUs, with an average benchmark score of 7,723. The data shows that this is a mid-range part from a performance standpoint, and its nearest rivals are all within a narrow margin: the AMD Radeon 540 scores 7,673 (0.7% higher), the AMD Radeon Pro WX 3100 scores 7,580 (1.9% lower), and the Intel Arc A310 scores 7,550 (2.3% lower).

In Rust, the GPU’s role becomes evident when examining the measured FPS. At 1080p High, the combo averages 60 FPS, which is on the edge of smooth gameplay. Moving to 1440p High, the average drops to 41 FPS, and at 4K High, it plunges to 24 FPS. This scaling pattern is a classic sign of GPU memory bandwidth and compute limitations. The 6 GB VRAM is a potential concern for Rust, which can be texture-heavy, but the data does not explicitly show VRAM capacity issues since even at 4K Ultra, the card manages to render at 19 FPS rather than failing to load textures. The GPU’s FP32 performance is 5.437 TFLOPS, which is modest for modern workloads, and this is reflected in the low frame rates at high resolutions. The pixel rate of 84.96 GPixel/s and texture rate of 169.9 GTexel/s are also limiting factors when the resolution increases, as the GPU must process more fragments and texels per frame.

The GTX 1660 Ti’s performance is further contextualized by its synthetic benchmarks: it scores 12,871 in Passmark G3D and 5,226 in GPU Compute. These numbers are not directly tied to Rust, but they establish the GPU’s overall capability. The 41st percentile ranking means that over half of all GPUs tested are faster, which explains why the combo’s overall rank in Rust is 2,520 out of 2,953. The GPU is clearly the weaker link in this pairing, as evidenced by the fact that reducing settings from Ultra to Low at any resolution yields a significant FPS increase — for example, at 1080p, Low (106 FPS) is more than double Ultra (46 FPS). This indicates that the GPU’s fill rate and shading power are the primary constraints, not the CPU’s ability to feed it data.

Resolution Scaling — how FPS drops from 1080p to 4K and what it says about the limiting component

Examining the measured FPS across resolutions reveals a consistent and steep decline, which is diagnostic of a GPU-bound system. At Low settings, the average FPS drops from 106 at 1080p to 73 at 1440p, and then to 43 at 4K. This represents a 31% drop from 1080p to 1440p, and a further 41% drop from 1440p to 4K. For High settings, the progression is 60 FPS at 1080p, 41 FPS at 1440p, and 24 FPS at 4K — a 32% drop to 1440p and a 41% drop to 4K. The relative consistency of these percentage drops across settings is telling: it suggests that the limiting factor scales with pixel count, not with graphical complexity, which is a textbook characteristic of a GPU bottleneck.

The CPU’s performance does not degrade with resolution in the same way. Since the CPU’s workload is primarily about game logic, physics, and entity management, it remains relatively constant regardless of whether the output is 1080p or 4K. The fact that the FPS drops so sharply as resolution increases means the GPU is running out of compute and memory bandwidth. For instance, the GTX 1660 Ti’s memory bandwidth of 288.0 GB/s is sufficient for 1080p but becomes strained at 4K where the framebuffer and texture fetches require more data per second. The 6 GB VRAM also becomes a factor, as higher resolutions often require more memory for buffers, but the data does not show a sudden collapse that would indicate VRAM overflow — instead, the FPS declines gradually, which is more consistent with raw compute limitations.

This resolution scaling behavior has a practical implication for users: the system is well-suited for 1080p gaming, where it can achieve playable frame rates across all settings, but it is not designed for 4K gaming without significant compromises. The data shows that even at 4K Low, the average FPS of 43 is below the typical 60 FPS target for smooth gameplay, and at 4K Medium it drops to 29 FPS. The 1440p results are borderline, with Low settings hitting 73 FPS, but High and Ultra falling to 41 and 31 FPS, respectively. This indicates that the GPU is the limiting component at resolutions above 1080p, and users should prioritize resolution reductions over setting reductions to maintain a consistent frame rate.

FAQ

Q: What is the best resolution for this CPU-GPU combo to achieve 60 FPS or higher?

A: Based on the data, 1080p is the only resolution where the combo consistently exceeds 60 FPS. At 1080p Low, the average is 106 FPS, and at 1080p High, it is 60 FPS. At 1440p, only Low settings reach 73 FPS, which is above 60 but not by a large margin, while High drops to 41 FPS. At 4K, no settings achieve 60 FPS, with the highest being 43 FPS on Low.

Q: How does the CPU’s performance compare to its nearest competitors?

A: The Intel Core Ultra 5 235 has an average benchmark score of 46,062. The AMD Ryzen AI 9 HX 375 scores 46,030, which is 0.1% lower, and the AMD EPYC 4364P scores 45,970, which is 0.2% lower. The Intel Core i9-13900HX scores 46,098, which is 0.1% higher. This indicates the Ultra 5 235 is statistically tied with these rivals in overall CPU performance.

Q: Is the GPU the main bottleneck in this system for Rust?

A: Yes, the data strongly suggests this. The FPS drops dramatically as resolution increases — from 106 FPS at 1080p Low to 43 FPS at 4K Low — while the CPU’s workload remains relatively constant. Additionally, the GPU’s 41st percentile ranking is much lower than the CPU’s 89th percentile, and the combo’s overall rank in Rust is 2,520 out of 2,953, indicating the GPU holds back the system.

Q: What is the impact of turning settings from Low to Ultra on frame rate?

A: The impact is significant. At 1080p, the average FPS goes from 106 on Low to 71 on Medium, 60 on High, and 46 on Ultra. At 1440p, it goes from 73 on Low to 49 on Medium, 41 on High, and 31 on Ultra. At 4K, it goes from 43 on Low to 29 on Medium, 24 on High, and 19 on Ultra. The largest proportional drop is from Low to Medium, which reduces FPS by roughly 33% at each resolution.

Q: How does the combo rank among all tested configurations in Rust?

A: The combo ranks 2,520 out of 2,953 tested combinations. This places it in the lower 15% of all tested systems, which is consistent with the GPU’s mid-range performance and the CPU’s high performance. The rank suggests that most other combinations tested are faster in Rust, likely due to having more powerful GPUs.

Q: Is there any setting where the system achieves a stable 60 FPS at 1440p?

A: According to the data, only Low settings at 1440p achieve an average of 73 FPS, which is above 60. However, Medium settings drop to 49 FPS, so Low is the only viable option for a 60+ FPS experience at 1440p. All other settings at 1440p fall below 60 FPS.

How This Combo Ranks

The combination of the Intel Core Ultra 5 235 and the NVIDIA GeForce GTX 1660 Ti is ranked 2,520 out of 2,953 tested combos in Rust. This places the system in the bottom 15% of all configurations, which is a surprising outcome given the CPU’s high performance. The CPU alone sits in the 89th percentile of all processors, but the GPU is in the 41st percentile, and this disparity is the primary reason for the low overall rank. The data indicates that while the CPU is capable of delivering high frame rates in isolation, the GPU cannot keep up with the demands of Rust at higher resolutions and settings.

To understand this rank, it is helpful to compare the GPU to its nearest rivals. The GTX 1660 Ti’s average benchmark score is 7,723, while the AMD Radeon 540 scores 7,673 (0.7% higher), the AMD Radeon Pro WX 3100 scores 7,580 (1.9% lower), and the Intel Arc A310 scores 7,550 (2.3% lower). These are all relatively low-end GPUs, and the fact that the GTX 1660 Ti is grouped with them underscores its positioning. When paired with a top-tier CPU like the Ultra 5 235, the system’s performance is capped by the GPU, resulting in a rank that reflects the GPU’s limitations rather than the CPU’s strengths. The measured FPS data supports this: at 1080p Low, the system hits 106 FPS, which is respectable, but at 4K Ultra, it falls to 19 FPS, which is unplayable. This rank is a clear indicator that for Rust, the GPU is the determining factor in overall system performance, and users with this combo should expect to play at 1080p for a satisfactory experience.

Settings Recommendations

Based on the measured FPS data, the optimal settings for this combo depend on the user’s performance target. For a smooth 60 FPS experience, the only viable option is 1080p with Low settings, which averages 106 FPS. This provides a significant margin above 60 FPS, allowing for occasional dips without dropping below the target. If the user is willing to accept slightly lower frame rates, 1080p High averages 60 FPS exactly, which is the minimum for smooth gameplay, but this leaves no headroom for demanding scenes. The Medium setting at 1080p averages 71 FPS, which is a good balance between visual quality and performance, offering a 12% improvement over High while still staying above 60 FPS.

For users with 1440p monitors, the data shows that only Low settings achieve an average above 60 FPS (73 FPS). Medium settings drop to 49 FPS, which is below the ideal target, and High and Ultra fall further to 41 and 31 FPS, respectively. Therefore, the recommendation for 1440p is to use Low settings if playability is the priority, or to consider lowering the resolution to 1080p for better frame rates. At 4K, no settings provide a playable experience, with the highest average being 43 FPS on Low. This resolution is not recommended for this combo, as even the lowest settings cannot maintain a smooth frame rate.

The best experience per the measured rows appears to be 1080p Medium, which offers 71 FPS average with a minimum of 60 FPS and a maximum of 82 FPS. This setting provides a solid balance, as it is 18% faster than High and only 33% slower than Low, while offering improved visual fidelity over Low. For users who prioritize frame rate above all else, 1080p Low is the safest choice, but for a balanced experience, 1080p Medium is the sweet spot. The data does not support using Ultra settings at any resolution, as the frame rates fall below 50 FPS even at 1080p, which is not ideal for a fast-paced survival game where responsiveness is key.

Measured FPS Breakdown

The measured FPS data provides a comprehensive view of how this combo performs across three resolutions and four settings. At 1920x1080, the average FPS for Low is 106, with no min or max recorded. Medium averages 71 FPS, with a minimum of 60 and a maximum of 82. High averages 60 FPS, and Ultra averages 46 FPS. This shows a clear progression where each step up in settings reduces performance by approximately 20-30%, with the largest single drop being from Low to Medium (33% reduction).

At 2560x1440, the average FPS for Low is 73, with no min or max recorded. Medium averages 49 FPS, with a minimum of 42 and a maximum of 56. High averages 41 FPS, and Ultra averages 31 FPS. The percentage drops are consistent with 1080p: from Low to Medium is a 33% reduction, from Medium to High is a 16% reduction, and from High to Ultra is a 24% reduction. The minimum FPS values for Medium (42) indicate that even this setting can dip below 60 FPS, which is a concern for smooth gameplay.

At 3840x2160, the average FPS for Low is 43, with no min or max recorded. Medium averages 29 FPS, with a minimum of 25 and a maximum of 33. High averages 24 FPS, and Ultra averages 19 FPS. The drop from Low to Medium is 33%, which is consistent with the other resolutions, but the absolute numbers are low enough to make the game unplayable at any setting. The minimum FPS of 25 at Medium further confirms that this resolution is not viable for this combo.

The data also shows that the FPS scaling from 1080p to 1440p is roughly 30-31% for Low and High settings, while the scaling from 1440p to 4K is roughly 41-42% for the same settings. This indicates that the GPU’s performance degrades more severely at higher resolutions, which is expected given its 6 GB VRAM and 288.0 GB/s bandwidth. The 1080p Medium setting is the only configuration that provides a minimum FPS above 60 (exactly 60), making it the most reliable choice for consistent performance.
